UC Berkeley Scientist Links Tech Addiction to Societal Divide
The Diary Of A CEO
Digital platforms deliberately exploit survival wiring and intermittent variable rewards to trap users, threatening to divide society into a small thinking class and a distracted majority.
Task-switching imposes a severe biological tax known as switch cost, slashing output by up to 60% and causing the average knowledge worker to lose over two hours daily to screen and app friction. (0:00)
Switching smartphone displays to grayscale removes hyper-stimulating visual cues, reducing average device usage by one hour per day, or seven hours each week. (45:00)
Structured focus sprints that pair calendar time blocking with granular execution lists enable professionals to double output while reducing error rates. (55:13)
Cognitive capacity aligns with distinct chronotype profiles—roughly 25% AM-shifted, 16% PM-shifted, and 59% biphasic—dictating the biological windows when high-leverage work must be scheduled. (100:59)
Detailed notes
## Background
Published on YouTube by The Diary Of A CEO on October 15, 2026, this interview features cognitive neuroscientist and UC Berkeley professor Dr. Sahar Yousef. According to the show description, the episode explores how individuals can overcome digital addiction, cut through brain fog, and reclaim deep focus by understanding the brain's biological operating systems and resisting tech platforms engineered to exploit human survival instincts.
## TL;DR
Dr. Sahar Yousef explains how modern technology platforms exploit evolutionary human biology, driving chronic distraction, emotional avoidance, and task-switching penalties that reduce workplace productivity by up to 60%. To reclaim cognitive control, she outlines behavioral interventions such as switching smartphones to grayscale, filtering VIP notifications, and executing structured, timed Focus Sprints with granular task lists. She emphasizes the necessity of respecting biological laws—including prioritizing a minimum of seven hours of sleep, scheduling genuine information-free brain breaks, and aligning demanding work with genetic chronotypes. Finally, Yousef warns against an emerging two-tiered society where an algorithmic underclass surrenders independent thought, urging individuals to establish deliberate cognitive hygiene and prime their attention toward meaningful long-term goals.
## Atmosphere & style
The dialogue maintains an urgent, diagnostic, and empowering tone, bridging rigorous academic neuroscience with practical workplace strategies. Dr. Yousef speaks with sharp, energetic conviction and relatable warmth, while host Steven Bartlett acts as an honest surrogate for the chronically distracted professional, candidly sharing his own screen addiction and daily cognitive friction. Hands-on exercises, such as a live iPad task-switching experiment, create a dynamic and grounded dynamic that validates audience struggles rather than inducing guilt. Listening feels like an eye-opening diagnostic intervention that replaces modern shame around digital overwhelm with tangible biological mastery.

## Detailed walkthrough
### [00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=0s) The Myth of Multitasking and the Reverse Neuroscience Toolkit
The conversation opens with an immediate cognitive challenge demonstrating the hidden friction of attention switching. Dr. Sahar Yousef explains that every shift in attention carries an involuntary cognitive tax, confirming that “multitasking is a myth.” Steven Bartlett agrees to run through a real-time exercise to gauge the time and mental energy squandered by bouncing between tasks. After experiencing the chaotic trial firsthand, Steven summarizes the damage: daily task-switching can slash output by 60%, with the average worker losing over two hours each day simply jumping between screens, apps, and separate obligations. As Dr. Yousef warns, remaining this divided traps people in an unfulfilling existence: “If we stay this distracted, we will live a life that we don't like living.”
Dr. Yousef presents a curated set of interventions, explaining that modern tech defaults are deliberately engineered by behavioral neuroscientists to optimize engagement, flooding the brain with stimulation like an endless stream of digital junk food with no natural stopping cue. To counteract this manipulation, she applies "reverse neuroscience," outlining simple baseline changes:
- **Grayscale Display:** Setting a smartphone screen to grayscale strips away artificial visual dopamine triggers. Lab research shows it reduces neurological stimulation enough that subjects cut phone usage by an average of one hour per day—saving seven full hours every week.
- **Long-Form Consumption:** Choosing long-form material over short-form clips repairs fragmented focus; over-consuming short snippets leaves attention spans shredded, induces brain fog, and forces the brain to operate at a lower baseline.
- **The Productivity Toolkit:** Utilizing a physical visual clock to anchor attention, scheduling structured "focus sprints" to up to double work output, and aligning deep work periods with an individual’s biological chronotype.
Steven pauses briefly before diving into the core framework to note a channel metric: roughly 58% of viewers are not yet subscribed. He asks listeners who have found value in the show to hit subscribe, noting that audience support directly funds higher-tier guests and richer production quality.

[02:21](https://www.youtube.com/watch?v=yePLuwL3FbM&t=141s) Biology Over Physics: Aligning With the Brain's Operating Laws
When Steven asks Dr. Yousef to distill her core purpose and its relevance to everyday listeners, she defines her mission as bringing actionable science education to the world so people can operate in harmony with their neurobiology. She points out a bizarre contradiction in modern culture: society accepts the laws of physics without debate—nobody wakes up and attempts to negotiate with gravity—yet humanity blithely ignores the governing laws of biology. School curricula drill children on facts and deliverables while completely skipping fundamental cognitive maintenance: how memory functions, how to reach flow states, how to regulate physiological stress, and how sleep works.
In professional environments, this blindness is amplified. Organizations obsess incessantly over the "what"—quarterly targets, project deliverables, and annual milestones—while ignoring the "how." Dr. Yousef highlights the irony that tech hubs like Silicon Valley pour immense capital into optimizing external software, yet ignore the foundational biological mechanism driving all innovation: the human brain. She argues that technology, while arguably humanity's most brilliant invention, currently generates immense friction because our daily habits directly conflict with our neural wiring.
> “This is my philosophy, that there are fundamental laws of how the brain and the body actually work. And I always liken these things to the laws of physics. There are laws of physics. We don't question the laws. Gravity. I don't ever wake up one morning and go, you know what? I want to do away with it. And I know that there are fundamental laws of biology, but we blissfully ignore these laws of biology.” — Dr. Sahar Yousef

[05:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=300s) Brain Fog, Digital Numbing, and the Glass Box Dilemma
Steven challenges Dr. Yousef to work backward from the user's felt experience, asking how individuals describe this biological friction in their own words. Dr. Yousef reveals that the most common complaint is debilitating "brain fog," along with an unsettling alienation from one's internal dialogue. She recounts an executive who once remarked in relief, “I can hear my own thoughts again,” a realization that revealed a broader crisis: society suffers from a pervasive discomfort with solitude. Every interstitial pocket of life—between calls, meetings, or chores—is instantly filled by scrolling and passive digital consumption. Because the mind is never granted unstructured downtime, it loses the space to synthesize ideas or spark independent insights. While she cannot cure diseases like cancer, she sees her mission as removing the cognitive logjams that hold people back from their best work.
Dr. Yousef shares her credentials and research foundation:
- **Academic Tenure:** Conducted her entire academic training at UC Berkeley.
- **Field of Expertise:** Specializes in cognitive neuroplasticity—the brain’s biological capacity to restructure, strengthen, and adapt over time.
- **The Becoming Superhuman Lab:** Founder and managing director of the lab, which is dedicated to human performance and cognitive scaling. The lab develops methods to elevate fluid intelligence, working memory, and sustained attention, with the operational mandate of helping high performers achieve peak output with minimal physiological strain.
Steven jokes about wanting to become superhuman himself, prompting Dr. Yousef to recall an observational study she ran with a senior executive at a Fortune 10 tech company. To diagnose executive workflow bottlenecks, she shadowed leaders for days at a time, recording granular inputs including meal timing, break cadence, and task transitions.
In this case, an exceptionally brilliant executive responsible for billions of dollars had been placed in a high-status "glass box"—a transparent office placed in the center of an open, bustling corporate floor. Although he was tasked with assembling a high-stakes board presentation requiring deep synthesis of cross-departmental data, his physical and digital architecture made deep focus biologically impossible:
- **Spatial Exposure:** Enclosed in glass, leaving him vulnerable to constant visual interruption from passersby.
- **Screen Saturation:** Working across a laptop and an auxiliary display showing incoming emails.
- **Multi-Device Alert Load:** Two smartphones (one personal, one professional) sitting face-up beside his keyboard, alongside an Apple Watch strapped to his wrist, continuously pinging him with notifications.
[10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=600s) The 47-Second Problem and Digital Hygiene
Dr. Sahar Yousef paints a vivid picture of the modern workplace distraction cycle. Someone sits down to focus, only to be immediately bombarded with sensory chaos: *"bzzz, bong, bing, boop, bop."* Coworkers walk by, and then a chief of staff interrupts with, *"Excuse me, don't forget this."* In reality, that person gets maybe 30 seconds of real concentration. Dr. Yousef cites research showing that the average knowledge worker stays focused on a single screen for just 47 seconds before getting distracted by another one.
To illustrate how broken this setup is, Dr. Yousef poses a hypothetical scenario to Steven Bartlett: imagine being given a billion dollars to cure cancer and tasking the world's most brilliant minds with solving this existential global challenge. Would you equip those scientists with Apple Watches pinging notifications, continuous Slack streams, and a calendar littered with calls, expecting them to cure the disease? Obviously not. You would put them in an environment that protects their deepest thinking instead of forcing them to play ping-pong with endless alerts. Dr. Yousef finds it ironic that having studied complex neurobiology, she now spends her career teaching what amounts to basic digital hygiene. As Dr. Yousef puts it: “Forget becoming superhuman. We just need to become human.” To perform, people must clear away the obstacles and honor their fundamental biology.

[12:08](https://www.youtube.com/watch?v=yePLuwL3FbM&t=728s) The Foundational Domino: Putting Out the Sleep Fire
Steven Bartlett breaks in to announce a Diary of a CEO first: turning the episode's insights into a live, interactive online workshop with Dr. Yousef so viewers can convert the science into lasting practical habits. Returning to the conversation, Steven notes that whether one is an executive or not, everyone lives in an intensely noisy world. He points to a physical box on the table and asks where an individual must begin to clear away the clutter and do the best work of their life.
Dr. Yousef answers unequivocally: sleep is the foundational first domino. She shares that she frequently consults with exhausted, haggard startup founders who want advice on how to improve performance by 1% while averaging only five hours of sleep a night. Dr. Yousef uses a mechanic metaphor to describe this disconnect: it is like driving a car into a repair shop while the vehicle is actively engulfed in flames, and the driver asks, *"Can we soup up the engine?"* As Dr. Yousef remarks: “Dude, let's put the fire out first. I don't even know where to begin to assess your baseline performance.”
- Sleep is the biological foundation; without it, assessing baseline cognitive performance is impossible.
- Adults require a strict minimum of seven hours of sleep per night.
- Chronic sleep deprivation directly damages executive cognitive performance and emotional regulation, making individuals irritable and reactive in professional settings.

[14:11](https://www.youtube.com/watch?v=yePLuwL3FbM&t=851s) The Direct Connection Between Focus, Memory, and Learning
Beyond sleep, Dr. Yousef identifies an individual's relationship with technology as a global crisis affecting people of all ages, from young children to senior citizens. Steven introduces a phone lockbox onto the studio table, and Dr. Yousef encourages him to lock his phone inside to demonstrate creating physical boundaries. While a specialized lockbox is not strictly mandatory, the human brain operates as a monotasking focus engine, and physical barriers help protect that state.
Dr. Yousef argues that attention and memory are inextricably linked. Memory is effectively the neurological equivalent of learning. You cannot retain or learn anything that fails to enter your attentional aperture in the first place. Ever since the advent of smartphones and relentless digital notifications, human sustained attention spans have followed a steady, linear decline. If someone spends their entire workday monitoring an inbox, they have no viable strategy for producing deep, high-value thoughts.

[17:28](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1048s) The Default Settings Trap and Big Tech Engagement
Steven raises the universal rebuttal that prevents people from cutting off their communications: the anxiety over missing an emergency. People leave their email and WhatsApp open all day thinking, *"What if something happens?"* or *"What if my fiancé needs to be let into the house?"* Dr. Yousef acknowledges these concerns as real "fires," but notes that society long ago solved this issue in the physical world.
Using postal mail as an analogy, Dr. Yousef explains that when an urgent, critical package arrives, a carrier knocks on the door and demands a physical signature. That audible knock represents an actual emergency notification. Everything else—junk mail, routine catalogs, standard envelopes—gets left quietly in the mailbox to be sorted through later. Dr. Yousef emphasizes that we must stop letting ordinary correspondence masquerade as an emergency: “Smart enough. We should respect ourselves enough. Truly, I am. To demand better than the default settings that our apps, our email, our phones come with.”
These default settings are engineered intentionally. Dr. Yousef points out that behavioral and cognitive neuroscientists work directly for tech platforms to maximize platform stickiness. This manipulation is not confined to social media like TikTok; it underpins the enterprise software running corporate life, such as Microsoft Outlook and Slack. Enterprise software providers renew massive multi-million-dollar annual contracts by proving sky-high engagement metrics. Because product developers must prove that employees are using their tools 24/7, every app and operating system is pre-configured by default to generate maximum interruption.
- The physical mail analogy: Urgent matters demand a signature at the door (VIP interruptions), while ordinary matters wait inside the mailbox.
- Enterprise communication platforms (e.g., Slack, email) are designed around user engagement metrics to justify contract renewals, incentivizing platforms to keep workers constantly reacting.
[20:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1200s) The Default Settings Trap and the Illusion of "Productivity Software"
Dr. Sahar Yousef challenges the core premise of modern corporate communication tools, arguing that their default settings are engineered solely for engagement rather than genuine productivity. To illustrate this disconnect, she compares software creators to candy manufacturers. A chocolate company’s bottom line is simple profit incentive—to sell as much candy as humanly possible—and it is neither their concern nor their business if the consumer develops diabetes or suffers from chronic overconsumption. Messaging applications and email clients operate on the exact same commercial incentives, treating human attention and engagement as their primary currency. Everything from the satisfying "whoosh" sound played when sending an email to the precise frequency of a smartphone's haptic vibration has been scientifically tested and tailored by neuroscientists to keep users tethered to their screens.
Steven Bartlett highlights the paradox this creates in modern work: when these software platforms report to their board and investors, their primary success metric is daily active usage and engagement. Distraction and deep productivity are diametrically opposed, meaning tools like Slack distract knowledge workers under the guise of helping them do their jobs. Dr. Yousef clarifies that while she is not a Luddite—acknowledging that humanity has never collaborated at this scale across time zones—professionals must abandon blind trust in default software settings.
> “Everything from the vibrate functionality that you feel in your phone has been highly optimized by people like me to keep you obsessed with the thing and addicted to the thing.” — Dr. Sahar Yousef
> “I am better than the default settings. The default settings are not there to help you.” — Dr. Sahar Yousef

[22:45](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1365s) Cutting the Digital Umbilical Cord: The VIP Notification System
When Steven admits that his screen time sits at roughly ten hours a day due to an overwhelming fear of missing critical emergencies or urgent "fires," Dr. Yousef outlines an immediate tactical countermeasure: building a strict VIP notification protocol. Instead of leaving communication channels wide open to every ping, professionals should construct an explicit whitelist across their phones, messaging applications, and email inboxes. Only communications from designated VIPs—such as a partner, a direct boss, an executive superior, or a company's top fifteen clients—are granted permission to bypass device filters and interrupt the user.

end
For email management, Dr. Yousef uses targeted keyword filters rather than monitoring general inboxes. Because her first name is relatively uncommon, she configured rules to alert her only when someone writes "Sahar" directly in the body, ensuring she is not pulled away by passive CC threads. She laments the modern office reality where seven people are copied on an email thread simply chatting with one another to resolve their own localized issues. Leaders must preserve their cognitive bandwidth to lead rather than being hijacked by non-urgent conversational clutter.
> “My train of thought doesn't need to be interrupted when I'm finally sitting down to focus.” — Dr. Sahar Yousef
- **VIP notification targets:** A romantic partner, immediate manager, boss's boss, and the top 10–15 primary clients.
- **Email keyword filtering:** Setting inbox alerts for specific high-signal triggers, such as one's own first name, while keeping passive CC banter muted.

[24:35](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1475s) Default "No" vs. Default "Yes": Protecting Time as a Precious Resource
Steven reflects on the immense social pressure to respond instantly and appease colleagues, wondering whether intensely focused individuals are inevitably perceived as rude because they have learned to resist people-pleasing. When asked to name the most focused person she knows, Dr. Yousef immediately identifies her husband, who is sitting nearby in the studio. They run their company together, and she notes that their working relationship thrives on an opposing balance of defaults: she is a "default yes" person drawn toward exciting, shiny opportunities, whereas he is an unyielding "default no" person who ferociously protects his cognitive resources.
Every inbound project and invitation becomes an internal debate between her desire for impact and his strict commitment to core objectives. Her husband views his attention and his calendar as finite assets. Rather than feeling social guilt about skipping meetings, he operates on the pragmatic calculation that his presence at most routine discussions adds little value, whereas declining them protects the uninterrupted deep work required to generate high-leverage ideas that elevate the entire company.
> “Yeah, maybe it's disappointing to some that I did not make it to that meeting, but I think people will find over time that my unique contribution to that meeting would have not been relevant.” — Dr. Sahar Yousef (channeling her husband)

[26:10](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1570s) Signal vs. Noise: What Steve Jobs and Elon Musk Understood About Focus
Steven recalls an insight shared with him during an interview with Kevin O'Leary regarding how Steve Jobs and Elon Musk operated. O'Leary described their exceptional productivity as an uncompromising 80/20 division between "signal" (the vital, transformative objective) and "noise" (everything else). Jobs had a relentless intolerance for conversational drift, constantly interrupting meetings to demand why the team was wasting time discussing noise rather than the signal.
Steven reinforces this with an anecdote from former Apple design chief Jony Ive, who explained that true focus is widely misunderstood. Focus is not merely deciding to perform one scheduled task over another; it requires turning down brilliant, captivating initiatives that you are deeply passionate about because they do not serve the singular primary mission. Jobs regularly tested Ive by asking what great concepts he had sacrificed that day, refusing to accept easy answers about rejecting ideas Ive was never interested in anyway. Furthermore, O'Leary observed that Elon Musk possessed an even more extreme level of this hyper-focused filtering than Jobs. Dr. Yousef notes that in information theory and cognitive performance, it is far more effective to aggressively eliminate noise first than to try to amplify the signal.
> “Focus is waking up in the morning and thinking something is a brilliant idea and with every bone in your body you know that that thing is brilliant and you want to do it and you say no to it anyway.” — Steven Bartlett (recounting Jony Ive)

[28:35](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1715s) The Monotasking Brain and the Evolutionary Cost of the Modern Office
Dr. Yousef reframes human attention around evolutionary biology, emphasizing that the human brain is strictly a "monotasking machine" rather than a system built for context switching. In the animal kingdom, humans are physically unimpressive: humans lack razor-sharp teeth, long claws, and raw muscle mass to fight off apex predators. The sole mechanism that ensured human survival and eventual dominance was the brain's capacity to out-think, out-strategize, and focus on one critical problem at a time.
Because survival depended on vigilance, roughly one-third of the human cerebral cortex's real estate is dedicated exclusively to sensory intake—specifically looking and listening. Humans evolved to constantly eavesdrop, track peripheral visual shifts, and jolt at sudden sounds. When this threat-detection machinery is placed into a modern open-plan workplace or a transparent glass executive office, workers are subjected to relentless biological stimulation. Watching colleagues constantly stroll past and overhearing fragmented background chatter keeps the brain in a perpetual state of hypervigilance, making it biologically exhausting to extract signal from surrounding environmental noise.
> “We're designed to be hypervigilant to anything that might come in our environment, which I mean, think of an open office, think of a typical setup where people are working.” — Dr. Sahar Yousef
- **Cortical allocation:** Approximately one-third of the human cortex is dedicated solely to processing visual and auditory inputs.
- **Evolutionary vulnerability:** Human physical puniness required extreme cognitive monotasking and environmental vigilance to avoid predators, an architecture that is heavily exploited by modern, chaotic office layouts.
[30:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1800s) Emotional Avoidance and the Urge to Escape Discomfort
Steven Bartlett reflects on how brilliance is being siphoned away from human advancement, pointing out that distractions seem to manifest in two distinct ways. The first is external interruption: an Apple Watch vibrates, a phone pings, or a notification flashes on screen. The second is internal avoidance: while in the middle of a demanding, tricky task—such as writing an essay—the moment slight discomfort or friction arises, a person instinctively reaches for their phone to chat on WhatsApp about weekend plans. Dr. Sahar Yousef confirms that this reflects fundamental human biology. She explains that the human brain operates as a relentless problem-solving mechanism governed by an innate aversion to discomfort. When people experience negative emotional states—including overwhelm, stress, anxiety, confusion, depression, FOMO, loneliness, anger, or frustration—the brain treats that feeling as a problem to eliminate immediately.
Addressing the root cause head-on demands substantial cognitive effort, so the brain naturally opts for emotional avoidance. In the modern landscape, technology offers an unprecedented escape hatch. Platforms like TikTok, fast-food outlets like Shake Shack, and online pornography function as immediate numbing agents that provide a fast, cheap exit from internal reality. Dr. Yousef emphasizes that acknowledging this tendency is the first step toward reclaiming focus, because our devices were intentionally engineered to serve as friction-free portals out of uncomfortable moments.
Steven connects this compulsive avoidance to classic behavioral psychology research in which participants were placed alone in a room with only their thoughts and an electrocution button. Prior to the isolation period, participants had sampled the shock and stated they would pay money to avoid experiencing it again. Yet, when left alone with nothing to do, a significant number chose to repeatedly press the button and shock themselves rather than sit in silence—with men shocking themselves far more than women, and one individual shocking himself hundreds of times. Steven draws a direct parallel to our modern relationship with devices, admitting his own vulnerability: “When my phone dies, it's like a mild feeling of anxiety when my phone dies and I'm most certainly addicted to my phone.” He notes that he checks his phone around 200 times a day, recognizing that people routinely choose digital overstimulation over sitting quietly with themselves.
- Common discomforts driving digital avoidance: overwhelm, stress, anxiety, confusion, mild depression, FOMO, loneliness, anger, and frustration.
- The solitary confinement electric shock study demonstrates that humans often prefer physical pain and self-administered shocks over solitary idleness.
- Dr. Yousef states: “The human brain is a problem-solving machine.”
- Steven Bartlett emphasizes his frustration with lost potential: “I want our species to keep advancing and I want us to advance as fast as humanly possible.”

When Steven asks what steps beyond turning off notifications and removing the phone during deep work are needed, Dr. Yousef explains that Big Tech has systematically hijacked the human brain by running the exact same playbook perfected by the industrial food sector. Just as food manufacturers exploited the fundamental biological necessity to eat in order to engineer addiction to sugar and ultra-processed ingredients, technology companies exploit our basic human needs for communication and connection to engineer digital dependency.
Dr. Yousef breaks down this predatory engineering into a shared three-part framework:
```mermaid

accTitle: The Shared Three-Part Exploitation Framework

subgraph Food["Industrial Food Industry"]
F1["Inject Sugar, Fat, and Salt<br/>(Exploit evolutionary jackpot cues)"]
F2["Eliminate Preparation Friction<br/>(Fast food, snack bars, packaging)"]
F3["Remove Satiating Nutrients<br/>(Strip fiber and protein)"]
F1 --> F2 --> F3
end
First, both industries dramatically elevate sensory stimulation. Humans evolved in environments of caloric scarcity where sweet, fatty, and salty tastes signaled life-saving caloric jackpots. Modern food manufacturers exploit this evolutionary bias by injecting refined sugar into almost every product—including standard loaves of bread in the United States where sugar serves no culinary necessity. In technology, companies mimic this stimulation by super-saturating interface colors and tuning the light emitted from screens. Because the visual cortex in the occipital lobe occupies an immense portion of the brain's processing capacity, hyper-saturated icons trigger intense neurological arousal. Dr. Yousef compares device displays to the visual overstimulation of a casino floor, where bright flashing lights dominate and neutral palettes are strictly forbidden. Tech companies supplement this visual saturation with hyper-paced, short-form reels to ensure the user cannot look away.
Second, both industries aggressively reduce friction. Fast food removed the necessity of shopping, chopping, and cooking a meal, making high-calorie snacks readily accessible in portable, single-serve packages. Technology platforms followed suit by removing every barrier between the user and consumption, enabling instant device unlocks, one-tap app launches, and frictionless infinite feeds.
Third, both industries strip out natural satiation cues. In real food, satiety is triggered biologically by fiber and protein—elements that signal to the brain that the stomach is full. Ultra-processed candy and junk foods deliberately strip out protein and fiber so the consumer never experiences genuine fullness. Similarly, digital feeds strip away natural stopping mechanisms, keeping the brain continuously consuming without ever reaching a state of informational satiety.
- As Dr. Yousef argues: “I find that it is eerily similar to how the food industry got us addicted to sugar and processed food.”
- High color saturation on mobile operating systems and app icons is purposefully calibrated to overstimulate the visual cortex in the occipital lobe.
- Both junk food and short-form digital media are engineered to be hyper-stimulating, low-friction, and non-satiating.

[36:38](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2198s) Intermittent Variable Rewards and the Algorithm's Jackpot Trap
Dr. Yousef moves into the psychological mechanics that keep users endlessly scrolling: the principle of intermittent variable rewards. Steven recalls learning about B.F. Skinner's operant conditioning experiments with pigeons at age sixteen, where unpredictable reward schedules produced obsessive behavior. Dr. Yousef explains that human beings do not crave perfectly predictable rewards; instead, compulsion peaks when rewards are delivered on an unpredictable, variable schedule. When users know a payoff exists but cannot predict which swipe will deliver it, their dopamine systems remain on high alert.
Dr. Yousef reveals how recommendation algorithms exploit this dynamic during a user session. The algorithm maintains an extensive profile of the user's specific tastes, archiving high-performing content it knows with high probability they will enjoy. However, when a user first opens an app, the platform does not immediately deliver its best material. Because the user has just entered the platform with fresh energy and time to spare, the algorithm intentionally serves mediocre, lukewarm content. It measures how long an individual user will tolerate low-to-medium entertainment before becoming bored and preparing to exit.
Right at the exact threshold where the user is about to abandon the app, the algorithm deploys a jackpot—such as a compelling clip of Steven Bartlett's podcast. That sudden dopamine hit rewards the user's persistence, instantly resetting their attention clock and trapping them in another cycle of scrolling. Steven observes that viewers watching their conversation on a social media reel might be experiencing that precise algorithmic mechanism in real time.
Dr. Yousef draws an analogy between this algorithmic manipulation and the dynamics of toxic interpersonal relationships. In destructive partnerships, one partner may act dismissive, distant, or verbally hostile, only to abruptly deliver intense affection through love bombing. The unpredictability of the validation hooks the recipient's neurochemistry far more deeply than steady, healthy affection ever could. The digital feed operates on the identical psychological architecture: withholding satisfaction through stretches of mediocre content, only to deliver intermittent, irresistible rewards that reinforce compulsive scrolling.
- Dr. Yousef summarizes human reward psychology: “Human beings, believe it or not, do not love consistent reward.”
- Social algorithms intentionally meter out mediocre posts during early session minutes, calculating the user's drop-off point before delivering high-value content.
- Intermittent reinforcement schedules in algorithmic feeds mirror the psychological cycle of love bombing and withdrawal seen in toxic relationships.
[40:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2400s) The Slot Machine Mechanism: How Algorithms Hijack Biology
Dr. Sahar Yousef explains that social media addiction does not occur because platforms deliver uninterrupted satisfaction; rather, it thrives on unpredictability. If an algorithmic feed delivered exclusively desired clips—such as five straight hours of *The Diary Of A CEO* clips without interruption—the user would paradoxically be far less prone to addiction. The neurological trap relies on an unpredictable variable reward schedule: the user never knows when the high-value payout is coming.
Dr. Yousef points out that this is precisely how casinos program slot machines:
> “Dude, you know that slot machines are programmed. It's a computer program. It's all math. They want you to lose a bunch of money, be in the red, and then have you make up a dollar fifty and then be like, ‘Oh, I'm back in.’ And this is the human game.”
Social media algorithms apply that exact mathematical architecture to intensify psychological stimulation. Simultaneously, tech platforms systematically strip away friction. In the early days of platforms like YouTube and Instagram, interfaces featured built-in "backstops" such as pagination (e.g., clicking from Page 1 to Page 2) and feeds strictly limited to accounts the user followed. Steven Bartlett points out that on early Instagram, users would simply run out of updates: "That's it. That's all for today. Come back tomorrow for maybe your friend posted another picture of their sandwich." Modern platforms replaced those natural stopping points with the infinite scroll, which Dr. Yousef compares to standing at a buffet with one's mouth open while an endless assembly line of food and candy pours in.

[42:15](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2535s) Decreased Satiation: Digital Junk Calories and Loneliness
Beyond raising stimulation and eliminating friction, social media companies deploy a third, deeply damaging tactic: reducing satiation. Dr. Yousef notes that human beings possess an innate, survival-driven biological need for social connection and community. Rather than satisfying this hunger, social platforms substitute an illusion of intimacy. Clinical and behavioral data demonstrate that the longer individuals linger on social apps, the lonelier they become. When someone sits alone at home experiencing isolation and fear of missing out (FOMO), grabbing a smartphone represents the quickest and cheapest attempt to satisfy that urge.
Dr. Yousef analogizes this behavior to eating Skittles when hungry for a nourishing meal. While candy provides raw calories, consuming fast sugar triggers an immediate spike followed by a precipitous crash. Bartlett observes: "If I have these junk calories, then in six hours' time, I'm back looking for more junk calories." In the exact same way, the brain possesses a fundamental biological drive for novelty and learning to promote survival—seeking facts and patterns that unlock real-world success. Short-form video feeds simulate learning by serving thirty-second reels packed with surface-level trivia, yet after closing the app, users fail to retain any of it. While deep, multi-hour formats actually nourish and satiate that cognitive drive, short-form clips leave the user depleted, unfulfilled, and craving another temporary dopamine hit.
---
[45:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2700s) The Reverse Uno: Grayscale and Cognitive Reset
Dr. Yousef argues that society is beginning to recognize this psychological manipulation and can fight back using what she terms a "Reverse Uno" strategy—applying principles of cognitive neuroscience to neutralize the platforms' behavioral traps:
> “The default settings are not here to help you. The default settings are here to help them make money off of your attention and your time. So you are better than the default settings, Steven.”
To counter hyper-stimulation, Dr. Yousef advises users to open their phone settings and switch the display to grayscale. Stripping color removes the neurological triggers that draw the eye, making the device appear inert and unappealing. This visual change makes it far easier to resist reflexive, late-night binge scrolling when willpower runs thin.
Addressing Bartlett’s question about whether empirical data backs this intervention, Dr. Yousef shares findings from an experiment run within her own research lab:
- A large cohort of healthy working professionals switched their smartphones to grayscale for three continuous weeks.
- Participants reduced their daily smartphone usage by an average of **one full hour per day**.
- This reduction restored **seven hours per week** of focused time—time individuals could reallocate to exercising, reading books, or resting.

[47:35](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2855s) Deep Media Diets and the Collapse of Attention
Dr. Yousef emphasizes that the ultimate goal is not to demonize screen time entirely, but to adopt an intentional "content diet" centered on long-form engagement over fragmented snippets. Long-form media, such as high-caliber films, has been scientifically shown to enhance empathy and lengthen sustained attention spans in young people. She encourages people to cultivate a deliberate viewing ritual—getting into pajamas, making popcorn, dimming the lights, and giving a story their full, undivided presence.
Instead, modern audiences routinely exhibit fractured attention, pairing television viewing with endless smartphone scrolling. Entertainment studios now manufacture content under the cynical assumption that viewers are distracted by a second screen. Dr. Yousef voices sharp concern over this degradation of baseline cognitive capacity:
> “How are you supposed to do that if you can't even pay attention to a fucking movie anymore?”
Bartlett validates this observation with a personal story from the previous evening, when he watched an intricate, vintage film featuring dense exposition and made-up planet names like "Kololubulu." He realized he had to expend tremendous conscious effort to focus on every line of dialogue to keep up with the plot. As a child, sitting on a sofa and watching a movie without distraction felt effortless; now, modern media conditioning creates an uncomfortable friction against deep, uninterrupted narrative immersion. Dr. Yousef cautions that while individuals may claim they prefer short-form content, overloading on rapid-fire media triggers documented rises in anxiety and depression, degrades attention spans, and leaves human brains functioning at a severely impaired level.
[50:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3000s) Satiating Fundamental Needs vs. Regrettable Screen Time
Dr. Sahar Yousef emphasizes that while overconsuming short-form digital content is ultimately an individual choice, people must recognize that excessive scrolling stems from real, unmet biological and social needs. The path to genuine satiety does not happen through an algorithm; it happens offline in real life: learning new skills, spending time with people in person, touching, talking, and gathering around dinner parties. When those core social needs are met, the craving for cheap dopamine vanishes, making individuals far less prone to scrolling until 2:00 AM and waking up drained.
Steven Bartlett connects this to a metric once championed by former Twitter CEO Jack Dorsey: reducing "regrettable minutes." Comparing short-form feeds to junk food, Steven notes that while eating a giant bag of Skittles feels good in the exact moment, it predictably causes regret and an emotional rollercoaster the following day. Research bears this out for social apps: roughly 60% of active TikTok users report experiencing negative welfare and state they would prefer to live in a world where the app did not exist. The platform ranks highest for user regret because people experience time distortion—opening the app only to lose one or two hours, walking away with no clarity about what they actually gained.

[52:15](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3135s) The Isolation Epidemic and Digital Portion Control
Dr. Yousef points out that society is beginning to wake up, with Financial Times data indicating that youth screen time began plateauing around 2022. Even so, the offline consequences of hyper-connectivity remain severe. Less than half of graduating high school seniors today have ever been on a date, compared to 80% to 90% in earlier generations. Real-world social infrastructure is collapsing alongside this shift: engagement in the UK nightclub scene has fallen by two-thirds, and an article in *The Atlantic* documented the gradual "death of dinner parties."
Because platforms exploit this profound isolation, Dr. Yousef advocates treating tech habits like nutritional portion control by intentionally designing environmental friction. Carrying a smartphone in a pocket all day is like placing an open beer in front of a recovering alcoholic during a workday; every spike of boredom or stress prompts an automatic reach for stimulation. The solution requires tactics such as using a "phone parking lot," keeping the device out of sight and out of mind, and shutting off non-essential notifications to lower baseline cognitive arousal. She argues that parents are exhausted from playing "bad cop" at home and that proactive digital friction frameworks should be taught in schools worldwide.
- Less than 50% of graduating high school seniors have ever been on a romantic date, down from an estimated 80% to 90% in prior generations.
- Attendance and participation across UK nightclubs has plummeted to roughly one-third of previous levels.
- “It's like sitting down with someone who is freshly trying to become sober as an alcoholic and just be like, 'You don't mind if I just put this beer down in front of you, do I? Or do you?'” explains Dr. Sahar Yousef.

Steven highlights exogenous ketone supplements as one of the top three interventions that deliver genuine cognitive gains and productivity improvements in his life. Developed by Stanford graduates, these liquid shots mimic the metabolic focus benefits of a ketogenic diet, providing direct mental energy that is supported by clinical research. Steven was so impressed by the data that he became a co-owner of the brand.
Steven also shares hiring advice for early-stage founders, arguing that the primary risk to an emerging company is rarely an imperfect product, but rather hiring the wrong candidate out of haste. Sifting through candidates can take 40 hours or more, driving founders to make fast, damaging hires that undermine team culture. He highlights LinkedIn Hiring Pro's AI-assisted recruitment tools, which assist with job descriptions, candidate filtering, and initial screening interviews, helping nearly 60% of hiring managers secure an interview-ready candidate within seven days.
- Exogenous ketone shots provide clean cellular brain energy equivalent to a ketogenic state without the dietary overhead.
- Nearly 60% of employers using LinkedIn Hiring Pro schedule candidate interviews within one week of posting.
[55:13](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3313s) The Focus Sprint: Steps 1 & 2 for Doubling Output
Steven asks how knowledge workers can consistently achieve deep work when tasks like writing and coding run directly into screen-based distraction. Dr. Yousef explains that her lab at UC Berkeley formalizes deep work into a specific method known as a "Focus Sprint." In empirical lab evaluations, executing a Focus Sprint allows professionals to achieve up to double their normal productivity while simultaneously reducing error rates and preventing mental exhaustion. The complete method consists of five distinct operational steps.
```mermaid

F --> G["Assign Strict Time Blocks per Sub-Unit"]
G --> H["Dopamine System Sustains Drive"]
end
Step1 --> Step2
```
The first step requires setting aside the time block in advance on an open calendar. Putting the sprint on the calendar engages the brain's anticipatory networks. Just as public speaking triggers anticipatory adrenaline, heart-rate spikes, and cortisol to prime the nervous system for an upcoming demand, knowing a sprint is scheduled generates an adaptive spike in alertness and physiological arousal before work begins. Furthermore, a visible calendar block relieves social pressure and communicative guilt by letting teammates know why an individual is temporarily unresponsive.
The second step is precisely defining and deconstructing the target task. Dopamine operates as the brain's primary motivation molecule, driving excitement and rewarding completion. Ambitious, ill-defined entries on a task list—such as simply planning to "work on the deck"—fail to engage this reward circuitry because the brain has no distinct finish line to anticipate. Instead, workers must "shop" a single item from their master task list, break it down into granular sub-units (such as completing slide three), and assign discrete micro-time blocks to each part.
- Controlled lab research demonstrates that running a structured Focus Sprint can double total output while lowering error rates.
- Anticipatory biological mechanisms release cortisol and adrenaline prior to a scheduled session, naturally boosting physiological arousal.
- “Now a focus sprint is a method of working... that according to research, our research, has allowed people to do up to two times as much as they would otherwise do while also reducing the number of mistakes,” states Dr. Sahar Yousef.
[01:00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3600s) Breaking Goals into Outputs and Execution Lists
Dr. Sahar Yousef explains that when structuring focus blocks, people frequently make the mistake of setting vague, input-based intentions—such as deciding to "work on," "think about," or "strategize" a project. Instead, a successful sprint requires a concrete, measurable output broken down into a granular execution list. She illustrates this by breaking down a workflow step by step: calculating that a slide will take roughly seven minutes to finish, drafting a quick follow-up email to a colleague named John to retrieve specific data needed for slide 17, and then assembling a specific table. Breaking work down this way stimulates anticipatory dopamine networks, creating momentum because the finish line is visible and defined.
Steven Bartlett observes that setting an execution list feels like substantial upfront effort. Dr. Yousef responds that creating this breakdown takes merely a minute and a half, but omitting it is precisely where people derail. When someone finishes step 1B and encounters ambiguity about step 1C or step 2, their momentum breaks: they pause, look around, and wonder what to tackle next, draining their cognitive energy on decision-making rather than execution.
> “I don't want you to figure out how to play the game when you're in the middle of the game,” Dr. Yousef emphasizes. “We need to outline what the heck the game is and then you're going to go into it be like let's go sprint and we go go go go go.”

[01:00:42](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3642s) The Refrigerator Analogy: MITs vs. LITs
Dr. Yousef introduces the framework her lab uses to organize workloads, comparing a master to-do list to a kitchen refrigerator, pantry, and freezer. Just as defrosted chicken represents a time-sensitive item that must be cooked immediately before spoiling, certain tasks carry genuine urgency. Every morning, before committing to work, an individual must assess total available time—such as an uninterrupted three-hour block—and select their Most Important Tasks (MITs). MITs are restricted to a maximum of one to three core items per day that genuinely define success. An effective research-backed test for selecting an MIT is asking: *What will your future self thank you for?*
Steven notes that natural human instincts push people to reach for whatever is comfortable, familiar, and immediately gratifying—avoiding uncomfortable domains like finance, investing, or operations. Dr. Yousef terms these minor chores Least Important Tasks (LITs). LITs encompass transactional activities like signing a DocuSign, answering a quick email, or ordering toilet paper on Amazon. While LITs provide "fast dopamine" through crossing items off a list, high-impact career and business advancement live on the side of "slow dopamine." LITs should not be abandoned entirely, but rather relegated to small 15-minute intervals between meetings, preserving unbroken deep-work blocks exclusively for MITs.
- **MITs (Most Important Tasks):** 1 to 3 non-negotiable items per day; high cognitive demand; driven by "slow dopamine"; directly advance long-term objectives.
- **LITs (Least Important Tasks):** Minor administrative tasks (DocuSigns, transactional emails, ordering supplies); driven by "fast dopamine"; best batched into 15-minute fringe periods.
- **Sprint Formats:** Sprints can be dedicated either to breaking down a single major MIT into 5- to 20-minute operational increments or to batching 15 LITs into a single rapid-fire clearing session.

[01:04:23](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3863s) Finding Your Everest and the Deathbed Exercise
When Steven asks how someone paralyzed by a sprawling to-do list of 69 tasks can determine what truly counts as an MIT, Dr. Yousef advises zooming out to uncover long-term direction: "What is your Everest?" If an individual understands where they want to be in five years, it becomes immediately apparent whether a prospective step leads toward the mountain or off a dangerous cliff. To establish ultimate clarity, she relies on contemplating mortality and visualizing one's deathbed, picturing reaching the age of 110 with the aid of future longevity medicine and reviewing what actually mattered.
> “What looking back on your life do you need to have experienced, accomplished, done, in order for you to leave with a smile on your face and to just say, 'It's been real, I did good, I had an amazing life, I did what I wanted to do here and I'm ready to go'?”
When Steven asks for her own reflection, Dr. Yousef shares that her core driver is loving deeply and practicing servant leadership, feeling a profound calling to improve human systems even when it requires major personal sacrifices.
Steven walks through his own visualization of the deathbed exercise:
- **Presence and Relationships:** Noticing who is in the room—his romantic partner and his future children gathered around the bed.
- **Living Proof:** Wanting his children to view his accomplishments as tangible proof of what they can achieve themselves.
- **Net-Positive Legacy:** Ensuring his family has clear, undeniable evidence of his philanthropic contribution and that his time on Earth made the world measurably better.
Steven observes that getting clear on those core values completely eliminates the urge to waste time on meaningless distractions: “Fuck the Skittles.” Dr. Yousef agrees, citing the work of Australian hospice nurse Bronnie Ware, who recorded the top regrets of dying individuals—none of whom ever wished they had spent more time scrolling their phones or watching television instead of being present with their loved ones and pursuing their life's mission.
[01:10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4200s) Regrets of the Dying, the Paradox of Connection, and Shared Flow
Reflecting on her experiences practicing death doula work, Dr. Sahar Yousef describes the profound clarity that emerges when sitting beside individuals who are passing away. She recounts the documented findings of a caregiver who kept a log asking dying patients about their ultimate regrets, noting that the single most universal answer was: “I wish I lived a life more true to myself and cared less about what others thought.” Steven Bartlett observes that in the grand scheme, even seeking the approval of one's closest family is an illusion, because no one can ever truly step inside another person’s mind. Humanity enters the world alone and exits alone. From the very first scream of a newborn infant—an immediate, terrified cry provoked by a sudden feeling of detachment from the mother—humans spend their entire existence yearning for belonging and intimate connection, trapped in the paradox that complete psychological merging is impossible.
Dr. Yousef points out that consciousness itself is endlessly fluid: because no two moments ever repeat, the person experiencing a moment changes continuously. Dr. Yousef jokes that every passing second turns her into “Sahar version 100 million,” constantly evolving. Steven counters that despite this isolation, there are unmistakable moments where two minds engage in an undeniable tango. He notes that conducting long, intimate three-hour podcast interviews delving into an individual’s childhood trauma often produces a shared, nearly spiritual frequency. Dr. Yousef strongly validates this, defining it as an energetic flow where the individual ego temporarily dissolves.
> “I think what is necessary for two humans to have that flow together, that energetic dance together is a loss of of the sense of self.” — Dr. Sahar Yousef
When individuals cling tightly to their personal identities, they remain hyper-aware of judgment and external perception. True relational magic occurs only when identity recedes and the separate concepts of "I" and "you" fuse into an effortless, shared "we."

Steven notes that this dynamic of conversational flow mirrors high-level cognitive work: when completely immersed in an engaging task, internal timekeeping shuts off entirely, leaving someone to look up and wonder where three or four hours went. Dr. Yousef links this directly to task architecture and dopamine. When tackling a massive, low-dopamine Most Important Task (MIT), the human brain reacts like a lab rat looking down an agonizingly long, complicated maze at a single block of cheese at the finish line—the sheer cognitive effort feels exhausting and uninviting. Conversely, Least Important Tasks (LITs) and high-distraction digital bites provide fast, effortless crumbs right at the entrance. The strategic neurobiological solution is to dismantle the monumental MIT and scatter it along the path in bite-sized pieces, transforming a daunting journey into a chain of micro-actions.
Dr. Yousef shares an anecdote about her husband’s ascent of Mount Kilimanjaro, a grueling physical undertaking she gladly declined in favor of mental challenges. He reported that the local Tanzanian guides and Sherpas, who effortlessly navigate the high altitudes with heavy packs as if it were second nature, continually repeat a single calming Swahili mantra: *"Polé polé"* ("Slowly, slowly"). Obsessing over the summit paralyzes a climber; survival and success depend solely on executing the immediate step right in front of them.
Steven connects this mindset directly to elite athletics through his close relationship with Sir David Brailsford, the mastermind of the British cycling team's dominance profiled in *Atomic Habits*:
- **Pedals Over Podiums:** Sir David Brailsford strictly prohibited his cyclists from fixating on Olympic podiums or world record times.
- **The Meditative State:** When track cycling legend Sir Chris Hoy fixated on the podium, his lap times visibly deteriorated. Once Brailsford trained him to detach from the end goal and focus entirely on the pedals, Hoy dropped into a flow state so deep that he would step off the bike at the finish line unable to recall the actual laps around the velodrome.
- **Overtime Driven by Progress:** When the cycling team began obsessing over microscopic gains rather than the end medal, staff stopped punching out at 5:00 p.m. and voluntarily stayed until 1:00 a.m. because they could palpably sense forward movement.
- **The Progress Principle:** A landmark *Harvard Business Review* study confirmed that the single most common variable marking an employee's best workday is experiencing a tangible sense of small, incremental progress. Converting an MIT into a sequence of small LITs artificially fuels this exact neurochemical momentum.
[01:17:40](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4660s) Cutting Distractions: Auditory Environments and Noise-Canceling Limits
Building on the foundation of breaking goals down, Dr. Yousef transitions to the third step of cognitive optimization: maximizing signal by aggressively removing obstacles rather than piling on new systems. Increasing performance requires turning down the environmental volume and eliminating interference.
> “Remove the obstacles, turn down the fucking noise.” — Dr. Sahar Yousef
Baseline cognitive hygiene demands treating attention like a sterile field: smartphones must be stored physically out of sight, and all notifications must be silenced. Steven asks Dr. Yousef what cognitive neuroscience reveals about working with headphones and listening to music. She clarifies that auditory preferences are highly individualized:
- **Silence vs. Sound:** A segment of the population thrives only in absolute silence and finds music actively disruptive to complex problem-solving.
- **Active Noise Cancellation (ANC):** For those unable to access quiet workspaces, noise-canceling headphones provide an essential acoustic shield.
- **The Auditory Threshold Warning:** Dr. Yousef cautions against using active noise-canceling headphones for more than three to four hours per day. Continuous sensory deprivation resets the brain’s baseline perception of acoustic reality. Prolonged daily isolation can cause the brain to become oversensitized and deeply overwhelmed by ordinary, real-world ambient sounds once the headphones are removed.
[01:20:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4800s) Audio Environments and State-Specific Playlists
Dr. Sahar Yousef cautions against using active noise-cancelling headphones all day long because human auditory biology rapidly adapts to the artificial silence. If you constantly block out ambient sound, your brain begins to believe that a dead-silent room is the normal baseline of the world. Once you finally remove the headphones, everyday background noises can suddenly feel intensely overwhelming, triggering acute overstimulation and anxiety. For that reason, Dr. Yousef recommends reserving noise cancellation strictly for dedicated focus periods: “So noise cancelling, I would say use it for focus sprints only.” If an individual plans for three hours of deep focus across a working day, those three hours should mark the boundary for active noise cancellation.
When choosing an auditory background, music can serve as an exceptional cognitive anchor if chosen intentionally. The ideal soundtrack features either no lyrics at all or lyrics in a foreign language the listener cannot comprehend, which prevents verbal processing circuits from competing with the task at hand. Dr. Yousef advises building a dedicated “focus mode” playlist that you condition your brain to associate exclusively with deep work over time. Rather than relying on a single, catch-all soundtrack for an entire day, high performers should maintain distinct playlists tailored to specific neurological modes, such as an email sprint playlist, an analytical deep-work playlist, and entirely different selections for evening decompression and sleep.
- Use noise cancellation selectively (such as during a 3-hour daily focus sprint quota) so the auditory system does not lose tolerance for real-world environmental noise.
- Music for focus must omit recognizable lyrical content to avoid semantic interference in working memory.
- Associative conditioning works best when you assign separate playlists to distinct cognitive states (focus sprints, email processing, evening wind-down).

[01:21:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4860s) The Progress Principle, Cleanup Songs, and Parkinson's Law
Once the auditory space is established, the next tactical lever is setting a timer. Dr. Yousef explains that humans, like most mammals, are wired to respond powerfully to visible markers of progress. While any visual meter or progress bar captures cognitive interest, watching a timer tick downward produces a heightened psychological urgency that sharpens focus and prompts people to hustle.
To illustrate how deadlines anchor attention, Dr. Yousef points to the universal phenomenon of classroom cleanup songs:
```mermaid

C --> D["Heightened Focus and Goal-Oriented Drive"]
end
subgraph Outcome["Execution"]
D --> E["Toys Stored / Work Condensed Before Song Ends"]
end
```
Without a structured boundary, young children attempting to clean up a room full of scattered toys will inevitably become distracted by the third item they touch and wander off. However, when a teacher starts a familiar cleanup song, the clear beginning, the definite ending, and the awareness that the song is running out transform their behavior. The children instantly become goal-oriented, scrambling to pack away the toys before the music finishes.
This behavioral pattern is directly tied to Parkinson's Law, which observes that work expands to fill whatever time is allocated to it. If an employee gives themselves an entire five hours to complete a presentation deck, the task will drag out across all five hours; if given a hard sixty-minute container, the brain condenses the effort to finish within the hour. Dr. Yousef recommends applying this constraint to everyday life—whether cleaning the house or running errands—because setting a visible countdown automatically accelerates execution.
---
[01:22:30](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4950s) Time Allocation as Life's Core Currency
Steven Bartlett reflects on an idea that reshaped his perspective five years prior: the realization that the primary lever of a person's existence is how they choose to allocate their time. Ultimately, every meaningful life outcome—from long-term cardiovascular health and career achievements to the intimacy shared with a partner and family on one's deathbed—is merely downstream of daily time allocation. While critics often argue that operating with timers and strict structures feels stressful, Bartlett counters that true stress stems from living an unintentional life where hours vanish without conscious direction.
Bartlett observes that modern professionals frequently spend their workdays floating aimlessly like "a plastic bag in the wind," tossed around by low-impact tasks (LITs) and external interruptions. Dr. Yousef agrees, joking that he came dangerously close to quoting Katy Perry, but affirms that the entire goal of her productivity framework is simply to hand people their life back. Modern workplace habits strip away the satisfaction highlighted by the progress principle; people are naturally driven to do high-quality work and yearn for the psychological equivalent of a childhood "gold star." When an endless barrage of notifications, calls, and meetings consumes their day, leaving core priorities untouched, workers feel unfulfilled and end up sacrificing evenings and weekends to catch up. By condensing work through timed focus sprints, workers leverage dopamine and hormonal drive to get things done rapidly, preserving their personal lives for what matters most.
> “Parkinson's law states that work will expand to fit the time that you give it. So if you give yourself an hour to get the damn deck done, it'll probably take an hour. If you give yourself five, it'll take five.” — Dr. Sahar Yousef

[01:26:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5160s) Visionary Boredom and the Fallacy of Modern Breaks
Steven shifts the conversation to the counterintuitive habits of visionaries like Steve Jobs and music producer Rick Rubin, both of whom relied heavily on radical stillness and stepping back from active work to see the future clearly. Jobs made famously contrarian, high-stakes decisions—such as eliminating Flash from mobile devices to improve video streaming, or discarding physical phone keyboards and styluses—by distancing himself from immediate technological noise. Bartlett wonders whether this deliberate embrace of boredom is what Dr. Yousef means when she speaks of taking a "brain break."
Dr. Yousef clarifies that a genuine brain break is a tactical protocol: it is defined strictly as a period during which the brain is not processing information. She forcefully critiques how the vast majority of modern workers attempt to rest:
> “Brain break is just defined as a short period of time where you're not processing information. And this brings me to really attacking how most humans seem to be taking breaks these days.” — Dr. Sahar Yousef
When contemporary workers finish an intense sprint, they almost universally reach for a smartphone to scroll TikTok, check social feeds, or scan the news. Dr. Yousef highlights a 2024 study published in *Nature* that tracked fatigue levels before work, after an intensive focus session, and following different categories of rest:
| Break Condition | Impact on Fatigue & Recovery | Description |
|:--- |:--- |:--- |
| **Exposure to Nature** | **Highest recovery** | Spending time in or viewing nature triggers visceral biological calm. |
| **Doing Nothing at All** | **High recovery** | Staring ahead, closing eyes, and ceasing informational intake allows neural reset. |
| **No Break** | **Poor recovery** | Continuous sustained work compounds exhaustion without rebound. |
| **TikTok-Style Scrolling** | **Worst recovery** | Floods the cognitive system with incoming stimuli, leaving mental fatigue unresolved. |
To illustrate why consuming content fails as a break, Dr. Yousef grabs a heavy physical block in the studio and uses a weightlifting analogy. When lifting heavy weights during an intense set, muscle fibers work under tremendous strain. Once the set ends, an athlete rests completely; they do not pick up smaller, low-grade weights and continue curling them between sets. Reading the news or scrolling through short-form video feeds while taking a "break" is the cognitive equivalent of continuing to pump low-grade weights. The brain's processing machinery—responsible for reading, evaluating, and absorbing information—remains fully active. To provide genuine neurological recovery, one must deliberately do nothing, or engage in an offline activity that shifts cognitive demands entirely away from information processing.
[01:30:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5400s) Designing High-Quality Breaks: Systems Over Willpower
Steven shares what constitutes an ideal cognitive reset for him: learning to DJ. He explains that outside the studio, four DJ decks are set up, and he has spent the last four years practicing the craft. Dr. Sahar validates this as an exceptional break because acquiring an immersive skill demands total engagement. As Steven puts it, “I'm totally focused because the song is about to end and I have to mix it. And it's the most locked in I am all day other than this.” This complete absorption prevents everyday anxieties and professional pressures from intruding into mental downtime.
For everyday work intervals where people cannot simply practice a complex hobby, Dr. Sahar advises relying strictly on physical systems rather than motivation. She rejects the concept of forcing behavioral change through sheer effort, stating, “I don't like willpower, like, 'Oh, I should really do that. I ought to do that.' Like, it's really difficult.” Instead of attempting to consciously resist checking email, news feeds, or LinkedIn during breaks, she designs environments that occupy both hands. Grabbing prepackaged convenience food leaves one hand free to doomscroll, whereas forcing physical food preparation blocks device usage entirely.
Rather than eating individually wrapped cheeses or pressing a button on a single-serve coffee pod machine, Dr. Sahar recommends keeping whole blocks of cheese that require opening a container and cutting slices with a knife, or putting a kettle on to boil water manually. Forcing two-handed physical involvement prevents simultaneous phone interaction, breaking the digital loop. The simplest effective workday resets involve rehydrating, having a snack, moving, getting fresh air, or stepping outside into direct natural sunlight.
- **Two-Handed Break Rule:** Eliminating grab-and-go snacks forces physical engagement with objects, eliminating the mechanical ability to hold and scroll on a smartphone.
- **Passive Recovery Protocols:** Stepping outdoors into natural light, brief walks, and basic rehydration provide baseline neurobiological resets between intense work sessions.

[01:31:55](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5515s) The Neuroscience of Creative Insight: Problem State vs. Solution State
When Steven asks how to crack complex, high-stakes problems and foster breakthrough creative insights, Dr. Sahar breaks down the neural mechanics of innovation. The initial phase demands total immersion in the data: a thinker must saturate their working memory and fully activate every neural network associated with the problem. However, staying chained to a desk trying to force a breakthrough creates cognitive gridlock. Citing an adage commonly attributed to Albert Einstein, she points out that “no problem can be solved by the same level of consciousness or the same mindset that created it.”
When an individual sits staring at a challenge without an immediate answer, their brain remains locked in the literal "problem state." Demanding that the identical network of activated neurons spontaneously generate a solution is biologically impossible. The mandatory next step is physical detachment: walking the dog, washing dishes, or taking a shower. Introducing a completely different physical environment or mundane stimulus loosens the rigid neural gridlock, allowing alternative electrical pathways to fire in the background.
```mermaid

Sudden creative illumination occurs when disparate, newly active electrical networks intersect with the primed problem networks. This unexpected collision produces the classic lightbulb moment where an obvious answer reveals itself. Genuine breakthroughs rarely emerge from straining harder at a screen; they materialize during the looseness that follows deliberate mental disengagement.

[01:34:04](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5644s) Rumination, Trauma Rehashing, and Pruning Neural Pathways
Steven asks whether the same neurobiological principles apply to chronic negative thinking and rumination. Dr. Sahar reacts with visible frustration toward modern culture's fixation on continuously discussing psychological wounds. While affirming that individuals must acknowledge and feel their emotions initially, she argues that perpetual post-event analysis solidifies negative circuits rather than healing them. In her view, “in the modern world, we've gotten ourselves into a bit of a pickle where we've made it okay to continue to rehash and exhaustively talk about and think about our traumas. When you do that, you're just deepening the damn neural networks.”
Rumination functions as repetitive neural rehearsal. Constantly retelling an identical victim narrative deepens the synaptic groove until the emotional injury transforms into permanent personal identity. Referencing the mechanics of habit formation popularized in *Atomic Habits*, she emphasizes that repeated electrical firing reinforces specific behavioral and cognitive architecture. The only method to extinguish an obsessive thought loop is immediate cognitive redirection the instant the pattern begins.
Dr. Sahar views the conscious mind as both the architect and the gardener of its underlying neurology. She likens persistent thought patterns to physical hypertrophy: if someone exercises only their right bicep while letting the left atrophy, the loaded muscle grows visibly disproportionate. To reshape the mind, an individual must recognize rumination instantly, interrupt the cycle, and redirect attention toward their chosen "Everest" or a productive counter-narrative. Summarizing the biological stakes of focus, she warns, “Be careful which ones you feed. Because whichever one you feed will in fact become stronger and louder.”

However, staring up at a monumental objective can provoke intense psychological paralysis, resembling the feeling of standing at the base of Mount Everest looking directly toward the summit. To overcome this overwhelm, his internal team relies on the "1% philosophy"—the discipline of breaking intimidating long-term visions into granular, non-threatening daily increments.
Reflecting on how foundational this marginal-gains approach has been to his personal business success, Steven introduces the return of the *1% Diary*.

[01:37:39](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5859s) The Science of When: Chronotypes and Circadian Rhythms
Steven pivots back to the physical objects in Dr. Sahar's productivity toolkit, asking why she includes a physical clock. Dr. Sahar explains that while prior techniques dictate the structure and execution of work, timing dictates physiological efficiency: “The clock represents the power and the science of when.”
To explain how the entire productivity framework fits together, Dr. Sahar maps each element to a distinct operational question:
- **What to do:** Defined by establishing an overarching "Everest" goal, followed by selecting Daily MITs (Most Important Tasks) and small LITs (Least Important Tasks) that move execution forward.
- **How to do it:** Executed through structured Focus Sprints—timed, high-intensity intervals that double cognitive throughput while driving error rates down.
- **When to do it:** Determined entirely by chronobiology and individual circadian timing.
Dr. Sahar stresses that productivity is not a one-size-fits-all schedule because humanity does not operate on a single shared circadian rhythm. Understanding an individual's specific biological clock dictates the optimal hours for deep cognitive sprints versus administrative catch-up, setting up the science of chronotypes.
[01:40:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6000s) The Biology of Chronotypes: AM vs. PM Shifted
While all humans and animals possess circadian rhythms, Dr. Sahar Yousef explains that we do not share a single identical biological schedule. Human chronotypes represent genetic and hormonal blueprints that dictate an individual's natural peaks in energy, cognitive capacity, and sleep-wake timing throughout a 24-hour cycle. “Your chronotype is your genetic biological ideal, time. It's essentially a profile of the hormones and your energy levels throughout the course of the day.” The first distinct category consists of AM-shifted individuals, colloquially known as early birds, whose cortisol levels surge naturally in the earliest hours of the morning. To test whether someone is truly AM-shifted, Dr. Yousef presents a clinical hypothetical: even if an AM-shifted person stays awake until 2:00 a.m. in a pitch-black, soundproof luxury hotel room without alarm clocks or children to disturb them, their pituitary gland and internal endocrine clock will still violently wake them up at 5:00 a.m., resulting in sleep deprivation because their biology overrides their sleep debt. Approximately 25% of the human population belongs to this AM-shifted group. Steven Bartlett laments that modern society, starting with early school schedules that force waking at 7:00 a.m. for a 9:00 a.m. start, is rigidly structured around this minority archetype.
Dr. Yousef points out that both she and Steven belong to the rarer, PM-shifted chronotype, which accounts for roughly 16% of the global population according to data gathered by her lab, the Becoming Superhuman Lab. Anthropologically, PM-shifted individuals served a vital evolutionary survival function: in primitive tribes, having the entire village fall asleep between 10:00 p.m. and 6:00 a.m. left the group completely defenseless against predators and rival tribes. Staggering wakefulness created a natural 24/7 watch rotation where night sentinels safeguarded the collective. While AM-shifted people experience their sharpest focus immediately upon waking and steadily lose steam throughout the day without a real second wind, PM-shifted individuals experience rising energy curves as the day progresses. Their peak cognitive clarity and stamina surface in the late afternoon and late into the night, often after 9:00 p.m. Dr. Yousef notes that PM-shifted people also demonstrate a pronounced tendency toward creative and artistic abilities, prompting Steven to jokingly ask her to repeat that statement directly to the camera.

[01:44:48](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6288s) Biphasic Rhythms and Aligning Work with Biological Peaks
The remaining majority of the human population belongs to the biphasic chronotype, named after the Latin terms for two phases or peaks. Dr. Yousef explains that biphasic individuals typically wake up feeling groggy, requiring roughly 45 minutes to an hour before ramping up to full alertness. Once primed, they hit their first major cognitive peak in the late morning, experience the sharpest afternoon energy drop among all three types, and then rally into a second wind later in the day if they manage their lifestyle and nutrition properly. Dr. Yousef insists that discovering one's chronotype is essential because attention span is dynamic rather than constant, and scheduling deep focus sprints must align with one's biological reality:
> “I am a big bag of blood, guts, and chemicals. I'm not a machine.”
Steven Bartlett and Dr. Yousef reflect on the daily friction PM-shifted individuals face because modern society does not accommodate late-day schedules. Steven shares a personal regret from that very morning: being in Los Angeles and managing cross-timezone obligations, he scheduled an important meeting for 7:00 a.m., only to suffer the cognitive consequences. “I woke up this morning and did a 7 AM meeting because it was very important and obviously i'm in la so you know i'm working to other people's schedules and i was shit.” In hindsight, he realized that because the meeting was critical, he should have pushed it as late as possible to protect his performance. Steven instituted a strict rule for *The Diary Of A CEO* to never begin recordings before 11:00 a.m. because early morning studio sessions yielded a brain that simply was not switched on. Both agree that while these scheduling adjustments seem marginal, their compounding impact over decades fundamentally transforms high-level output.

[01:47:38](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6458s) Inside Silicon Valley: Strategic Automaticity and Hijacked Habits
Shifting toward the broader societal crisis of chronic distraction, brain fog, and guilt, Steven asks what underlying macro forces are driving modern cognitive decline. Dr. Yousef acknowledges that her vantage point living in San Francisco and working with tech leaders offers a sobering, almost dystopian view into how consumer technologies are engineered. Steven brings up a confidential email exchange between them regarding Silicon Valley companies actively hiring neuroscientists to hijack human attention. Dr. Yousef explains that her scientific specialty—neuroplasticity and how the brain learns and alters its circuitry—is harnessed by software companies through a principle known as "strategic automaticity."
“Strategic automaticity is just getting people to do stuff without meaning to do stuff.” Drawing parallels to James Clear's bestselling book *Atomic Habits*, Dr. Yousef defines true automaticity as an action executed without conscious thought or deliberation. Just as a completely exhausted person will still mindlessly drag themselves off the couch to brush their teeth before sleeping, tech platforms engineer behavioral loops that bypass the deliberate, conscious brain. By turning digital consumption into involuntary neurological defaults, digital products extract attention effortlessly while users remain entirely unaware that their biological habit architecture has been deliberately weaponized against them.
[01:50:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6600s) Strategic Automaticity and Big Tech Recruitment
To illustrate how routine actions become wired into the brain, Dr. Sahar Yousef uses the everyday example of dental hygiene. As adults, we automatically brush our teeth before bed without debate, whereas children have to be repeatedly prompted and conditioned into doing it. Over time, that conscious deliberation drops away completely, turning the action into an involuntary behavior. Dr. Yousef terms this state "strategic automaticity"—removing deliberation so an action executes on autopilot. In her research on addiction, habit formation, and cognitive training, the goal is always to get people to adopt positive behaviors without needing constant external pings or reminders.
This exact mastery over human habit loops made cognitive scientists targets for major technology companies. Beginning around 2010 through 2014, Silicon Valley began aggressively recruiting researchers in Dr. Yousef’s field. She notes that while nondisclosure agreements legally prevent her from identifying the specific firms, she has received countless recruitment pitches. Steven Bartlett reads an excerpt of one such email aloud:
> “Hi Sahar, we came across your work on strategic automaticity at UC Berkeley, and we'd love to connect. We're looking to increase engagement and make our product more sticky. Would you be open to a quick call?”
Dr. Yousef clarifies that she does not view these companies or leaders as inherently evil; they are corporate operations creating lucrative opportunities. Tech firms promise academic researchers that they can continue their scientific investigations in-house, with the caveat that their behavioral findings will be applied directly to making digital platforms stickier. To illustrate the intensity of the temptation, Dr. Yousef shares that one offer included a compensation package worth four times her annual salary in public research. When platform engagement equates to multi-billion-dollar outcomes, hiring behavioral scientists to engineer habit loops is treated as an essential business investment.
[01:53:11](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6791s) The Rise of the "Thinking Class"
Looking ahead, Dr. Yousef argues that confronting our digital dependence is "going to be the Everest for our species." While artificial intelligence and modern technology hold transformative potential for medicine and economics, the downside risk of improper usage threatens human flourishing. When Steven Bartlett asks about her deepest fear, she recounts a sobering concept drawn directly from high-level industry meetings she has attended with AI executives: the impending emergence of an engineered, two-tiered society.
```mermaid

Unless deliberate interventions alter our trajectory, Dr. Yousef warns that society is constructing a reality dominated by an ultra-exclusive "thinking class"—a tiny subset of educated people who retain the attention span, discipline, and capacity to think critically, question dogma, and generate novel ideas. Dr. Yousef explains the grave societal consequences:
> “They will run the world, and the rest of the world will not be expected to think. Instead, their job will be to just do as they're told, and it is far easier to control a populace when they are distracted and not thinking.”
Her daily mission is to prevent this imbalance by illuminating what an intentional relationship between human minds and intelligent machines looks like. Without reclamation of personal agency, individuals risk drifting through lives they never chose, arriving on their deathbeds burdened with regret. This threat is particularly tragic given the monumental educational advancements of the past century, such as dramatic gains in global literacy and female educational equity. Where the twentieth century succeeded in expanding the thinking class, algorithmic extraction and unchecked AI reliance are causing that class to shrink back down.
[01:56:02](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6962s) AI, Context, and Biological Shortcuts
Steven Bartlett connects Dr. Yousef's warning to his own workplace dynamics. He shares that he deliberately writes by hand or drafts original text to resist having large language models (LLMs) think on his behalf. Just the day prior, Bartlett gave critical feedback to an employee who had submitted AI-generated material. He told the team member that while their real-world verbal reasoning was brilliant and rich in operational context, the written submissions had lost their unique personal voice and nuance because they were outsourced to ChatGPT.
Dr. Yousef validates Bartlett's observation, calling the temptation to outsource thought an inevitable consequence of evolutionary neurobiology. The brain operates under fundamental biological laws designed for survival, meaning it is genetically hardwired to exploit shortcuts whenever energy can be conserved. In prehistoric environments where calories were scarce, taking the shortest cognitive and energetic path to an outcome was essential for staying alive.
To explain this dynamic, she cites the foundational work of the late UC Berkeley professor Daniel Kahneman—the first psychologist to be awarded the Nobel Memorial Prize in Economic Sciences and the author of *Thinking, Fast and Slow*. Dr. Yousef stresses that cognitive biases are not functional defects or a "disease model"; they are evolutionary heuristics developed so the brain can quickly evaluate safety, affinity, and motivation without burning excessive metabolic energy on the overwhelming flood of sensory data in the environment. Dr. Yousef concludes with one of her favorite maxims from Kahneman on humanity's intrinsic resistance to sustained mental exertion:
> “Thinking is to humans as swimming is to cats: they can do it, but they would prefer not to.”
[02:00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7200s) Energy Conservation and Overcoming Tech Addiction Shame
Deep thinking runs directly counter to human evolutionary biology. Because our ancestors evolved in an environment of caloric scarcity, the brain was wired for energy conservation, resting, and biological preservation. Engaging in demanding cognitive work consumes significant calories, which an ancestral brain treats as an existential liability. Steven Bartlett jokes that burning through calories during intensive thinking makes him crave Skittles, noting that from a purely evolutionary viewpoint, higher calorie expenditure signaled that one's days were numbered.
Dr. Sahar Yousef emphasizes that acknowledging this evolutionary hardwiring should remove any shame or guilt people feel regarding their relationship with technology and habitual smartphone scrolling. Tech addiction is not a personal moral failure; platforms have been intentionally engineered by hundreds of behavioral neuroscientists to exploit these ancient survival circuits. She argues that instead of beating oneself up, individuals should treat digital dependence like a medical diagnosis: first take an objective "blood test" by collecting data on where attention is bleeding, assess the severity, and then implement targeted interventions.
As Dr. Sahar Yousef explains:
> “Lo and behold, you have a brain that we understand and your brain became addicted. So there's no shame in it. It's just what do we do next?”
- **Evolutionary drive:** Brains are naturally wired to conserve energy and avoid calorie-burning mental strain unless survival requires it.
- **Diagnostic approach:** Rather than succumbing to guilt over screen addiction, individuals should audit their behavioral baseline to pinpoint exactly where time and focus leak.

[02:02:18](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7338s) The Multitasking Test: Measuring the Switch Cost
Steven admits that he has long prided himself on being a context switcher, believing multitasking was a faster and more productive way to work. Dr. Yousef counters this by walking him through a practical demonstration on his iPad, recording the screen to illustrate the biological reality of "switch cost"—the tax in energy and time lost whenever attention jumps between distinct tracks.
To measure his baseline speed under monotasking conditions, Dr. Yousef instructs Steven to draw two horizontal lines. On the top line, he must write the sentence *"I'm a great multitasker"*, and on the bottom line, write the numbers 1 through 20 as fast as possible. Steven starts the timer and performs the two tasks sequentially, writing out the full sentence first and then rapidly counting up to 20, completing the entire exercise in 31 seconds.
Dr. Yousef then challenges him to repeat the exact same assignment, but this time forced into rapid alternation: writing the letter *I*, dropping down to write the number *1*, jumping up for the letter *’m* (or *A*), dropping down for *2*, and alternating back and forth character by character until both lines are complete. Steven anticipates the mental friction, telling her to simply stop him once the timer reaches his previous record of 31 seconds. As soon as the alternating test begins, Steven rapidly loses his place, exclaiming, *"Fuck, I forgot to count. That's weird,"* and labeling the attempt a *"shit show."* When Dr. Yousef calls time at 30 seconds, Steven has only progressed to the number 8.
As Dr. Sahar Yousef underscores:
> “Your switch cost is the amount of time and energy that you essentially waste every single time you switch your attention from A to B, B to C, so on and so forth. Biological law, another one. There's no free lunch. Every single time you do something with your biological being, you pay for it.”
---
[02:05:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7500s) Attentional Baggage and Cognitive Closure
Analyzing the results, Steven calculates that reaching only number 8 in 30 seconds means his speed dropped to roughly 40% of his baseline—making him 60% slower simply by toggling between letters and numbers. Beyond the dramatic plunge in efficiency, Steven notes that the alternating task felt deeply unpleasant, mentally exhausting, and painfully frustrating. Every time he jumped between the lines, his brain stalled in an awkward lag phase trying to retrieve where he was in the alphabet and what number came next.

```
Dr. Yousef identifies this psychological drag as "attentional residue," though she personally terms it "attentional baggage." When someone pivots away from an uncompleted task, lingering mental debris clings to the mind, contaminating the next objective. To prevent this depletion, workers must deliberately achieve "cognitive closure"—clearing the workspace and mentally closing the tab before boarding a new task. She reveals that the average modern knowledge worker loses over two hours every single day strictly to the friction of bouncing across apps, screens, and unfinished items.
Steven Bartlett reflects on the personal cost:
> “So on a daily basis, theoretically, I'm losing potentially 60% of my productivity, theoretically, just by switching between two different types of tasks at once.”
Dr. Sahar Yousef explains the compounding toll:
> “I call it attentional baggage because I find the visual that that creates better, meaning you carry into the next task all the shit, the baggage from the previous task, unless you close out.”
- **Performance penalty:** Multitasking reduced execution speed by 60% compared to pure sequential execution.
- **Cognitive friction:** Constant context switching requires re-onboarding at every shift, causing working-memory stalls.
- **Knowledge worker drain:** Bouncing between disparate screen tasks and notifications bleeds more than 2 hours of productive output per day.

Following the show's closing tradition, Steven asks Dr. Yousef the question left by the preceding guest: *"How can the audience become more lucky?"* Dr. Yousef rejects the idea that luck is purely random chance. Instead, she defines luck as an attentional mechanism: training and priming the brain's perceptual filters to actively scan the environment for specific opportunities.
To encounter luck, one must first clearly define their personal "Everest"—the overarching life objective identified through deathbed clarity. Without a vivid target, the brain has no frame of reference to recognize a fortunate break. Once the long-term vision (the podium) is clear, daily Most Important Tasks (the pedals) serve to orient day-to-day effort toward that horizon. Priming the mind with this clear signal directs its subconscious pattern-recognition networks to filter out background noise and latch onto relevant data. Conversely, Dr. Yousef cautions that if an individual wallows in rumination or adopts a victim mindset, the brain will prove equally obedient in seeking out evidence to validate their misfortune.
Dr. Sahar Yousef summarizes the neural mechanism of luck:
> “The way to become more lucky is to prime the mind, to train it, I would say, to look for luck.”
- **Perceptual priming:** The brain cannot spot fortunate opportunities until it is explicitly told what outcomes matter.
- **Signal over noise:** Centering daily thoughts on one's "Everest" and MITs primes the brain to identify serendipitous pathways.
- **Confirmation bias:** Neural networks actively hunt for environmental proof to validate whatever baseline mindset—fortunate or victimized—a person continually rehearses.
[02:10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7800s) Priming the Focus Machine: Finding Luck and the Barack Obama Challenge
Dr. Sahar Yousef explains that fixating on personal shortcomings traps people in a self-reinforcing victim mentality where their goal—their personal Mount Everest—feels impossibly far away. When the mind is locked in that state, all it perceives are closed doors and obstacles that feel insurmountable. The brain functions as an aggressive focus machine designed to scan the environment constantly and retrieve evidence confirming whatever core assumptions it holds. If an individual intentionally primes this neural system to look for pathways rather than dead ends, they will begin noticing that the apparent brick walls actually have handles and are doors waiting to be opened.

```
When Steven Bartlett playfully asks whether this concept simply amounts to manifestation or positive thinking, Dr. Sahar pushes back to anchor it in cognitive mechanics. She illustrates the principle with a concrete challenge: if Steven wakes up every single day actively focused on securing an elusive dream guest—such as getting Barack Obama onto the podcast—his brain will register subtle, relevant opportunities that a distracted mind would miss. “This thing is designed to look for the evidence and find the evidence that confirms its beliefs,” Dr. Sahar emphasizes. Keeping that target top of mind makes it far more probable that he will spot a casual opening, such as crossing paths with a former chief of staff at an event, ultimately turning what looks like serendipity into a biological byproduct of focused attention.
- The brain functions as a continuous scanning and filtering apparatus that validates pre-existing beliefs.
- Changing cognitive filters transforms perceived "brick walls" into actionable doors with handles.
- Keeping an explicit, ambitious goal top of mind primes attentional networks to notice serendipitous opportunities and key connections that would otherwise go entirely unnoticed.

[02:12:12](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7932s) Assessing the Mind: The MMM Institute and Digital Dependence Testing
Steven praises Dr. Sahar for her rare gift of demystifying dense, intimidating neuroscience with deep empathy for everyday listeners. He highlights the recent launch of her YouTube channel, urging the audience to subscribe directly rather than waiting for recommendation algorithms to deliver her insights. When Steven asks where viewers should go to delve deeper into her research, Dr. Sahar underscores her core mission: empowering individuals to regain control over their lives and live with genuine intentionality.
To build intentional habits, Dr. Sahar argues that individuals need hard baseline data about their cognitive health. People routinely schedule an annual physical, undergo comprehensive blood work, and monitor their physical organs, yet they ignore their cognitive well-being until catastrophic burnout or severe brain fog sets in. “We just wait for it to go to shit,” Dr. Sahar laments. “Like we wait for the car to be on fire and then we're like, oh, oops. No, we should have things that we're doing along the way.” To address this systemic gap, she emphasizes her commitment to making scientific cognitive tools universally accessible:
- Scientific evaluations must serve human well-being rather than commercial profits.
- Individuals can assess their attention span and evaluate their digital dependence using free scientific assessments at mmminstitute.org (the Mind, Machine, and Meaning Institute).
- Gathering baseline cognitive metrics gives individuals an objective starting point to diagnose digital strain before acute burnout occurs.

Cognitive neuroscientist Dr. Sahar Yousef argues that modern digital platforms exploit human evolutionary biology, degrading sustained attention through chronic task-switching and engineered dependency. She contends that regaining deep focus requires aligning daily work habits with neurobiological laws, enforcing strict digital boundaries, and using structured deep-work sprint protocols.
The Cognitive Friction of Multitasking and Distraction (0:00)
Dr. Yousef characterizes multitasking as a biological myth, asserting that shifting attention imposes an involuntary cognitive tax termed "attentional residue." In an in-studio test, alternating character-by-character between writing a sentence and numbers reduced speed by approximately 60% compared to sequential completion, while causing noticeable mental fatigue. Source data indicates that knowledge workers focus on a single screen for an average of just 47 seconds before switching, losing over two hours daily to context switching.
This fragmentation is reinforced by intentional software design. Dr. Yousef explains that tech platforms deploy "strategic automaticity" and intermittent variable reward schedules—mirroring casino slot machines—to exploit dopamine circuitry. Paralleling the industrial food sector's strategy of maximizing sensory stimulation, eliminating preparation friction, and stripping satiation cues, digital applications remove stopping points to make consumption habitual and involuntary.
Tactical Digital Hygiene and Environmental Friction (22:45)
To counter algorithmic capture, Dr. Yousef recommends applying "reverse neuroscience" by reintroducing environmental friction into device use. In an experiment conducted in her UC Berkeley lab, professionals who switched their smartphones to grayscale for three weeks reduced daily screen time by an average of one hour, reclaiming seven hours per week. Physical interventions, such as placing phones in lockboxes or out of sight during focused work, similarly protect single-task attention.
Communication channels require comparable filtering. Dr. Yousef advises constructing a strict VIP notification protocol where only critical contacts—such as a direct supervisor, partner, or key clients—can trigger breakthrough alerts, leaving standard messages to be batched and reviewed later. She also warns against passive breaks like social media scrolling, referencing a 2024 study in Nature indicating that digital feeds fail to relieve mental fatigue; true cognitive restoration requires tactile activities or periods free from information processing.
Structuring Focus Sprints and Task Architecture (55:13)
For demanding intellectual tasks, Dr. Yousef outlines the "Focus Sprint," a five-step method designed to double output while reducing error rates. The workflow begins by booking an uninterrupted hour on a public calendar, which engages biological anticipatory networks. Workers then spend roughly 90 seconds creating a granular execution list, defining concrete sub-unit outputs rather than vague intentions to eliminate mid-task decision fatigue and sustain dopaminergic momentum.
Daily workloads are organized by separating one to three high-leverage Most Important Tasks (MITs) from transactional Least Important Tasks (LITs), which are relegated to brief intervals between meetings. While lyric-free audio playlists can reinforce focus, Dr. Yousef cautions against using active noise-canceling headphones for more than three to four hours daily, warning that prolonged sensory deprivation can reset the brain's acoustic baseline and trigger overstimulation in ordinary ambient environments.
Biological Baselines and Future Cognitive Stratification (12:08)
Dr. Yousef insists that cognitive techniques fail without biological maintenance, identifying sleep as the foundational baseline. Adults require a strict minimum of seven hours of nightly sleep; chronic deprivation impairs executive function and emotional regulation. Work rhythms must also respect genetic chronotypes: roughly 25% of individuals are AM-shifted, waking early via natural cortisol surges, while the majority operates on later hormonal peaks that conflict with standard institutional schedules.
Looking ahead, Dr. Yousef warns of an emerging two-tiered society shaped by artificial intelligence and digital fragmentation. Drawing from discussions with technology executives, she forecasts a shrinking "thinking class" that retains deep focus and critical reasoning, contrasted with a distracted majority whose habits and decisions are guided by algorithmic nudges. She notes that tech susceptibility reflects ancient energy-conservation hardwiring rather than personal moral failure, urging objective tracking of cognitive health.
While Dr. Yousef outlines actionable individual protocols to restore cognitive control, the systemic challenge of reforming corporate notification cultures and rigid institutional schedules to accommodate biological variation remains largely unaddressed.

## Detailed walkthrough
### [00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=0s) 多任务处理的假象与大脑的“注意力税”
对谈一开始，Dr. Sahar Yousef 便打破了人们对多任务处理（multitasking）的幻想。在现场进行的一项注意力测试中，Steven Bartlett 亲身体验了频繁切换注意力的混乱与狼狈，并忍不住感叹这一过程简直是一场灾难。测试结果直观展现了人们在任务切换时所付出的代价：理论上，仅仅在两类不同的任务之间反复横跳，人每天就会损失高达 60% 的生产力。
Dr. Sahar Yousef 指出，现代人每天平均要浪费 2 个多小时在各种屏幕与任务之间来回跳转。“Every single time you switch your attention, you pay for it. So multitasking is a myth.” 如果人们持续任由这种注意力分散的状态蔓延，最终将过上一种自己并不满意的生活。当今各种科技产品的默认设置，本身就是由像认知神经科学家这类深谙人类心理机制的人专门设计的，其核心目的就是为了将用户参与度最大化，如同无节制地向大脑输送零食糖果，没有任何刹车机制。
为了反向利用神经科学夺回注意力，Dr. Sahar Yousef 提出了几项立竿见影的干预措施：
- **手机开启灰度模式（Grayscale）**：其实验室研究表明，将手机屏幕切换为黑白灰度后，能显著降低对大脑神经的刺激。实验参与者每天在手机上的使用时间平均减少了 1 个小时，一周便能夺回 7 个小时。
- **选择长内容而非短内容**：长期、过度摄入短视频等碎片化短内容，会导致注意力广度被彻底击碎，不仅使大脑在更低水平运转，还会让人主观上感觉更加糟糕。
- **专注冲刺（Focus Sprint）与生物时间型（Chronotype）**：在生产力工具包中引入计时器与专注冲刺机制，能让人完成比平时多达两倍的工作量；再结合个人的生物时间型，在生理节律最佳的时段展开冲刺，效率更会倍增。

### [02:21](https://www.youtube.com/watch?v=yePLuwL3FbM&t=141s) 生物学定律与被忽视的“工作方式”
Steven Bartlett 在简短向观众呼吁订阅频道后，向 Dr. Sahar Yousef 抛出了核心问题：她毕生致力于践行的使命究竟是什么？为什么这与每个普通人息息相关？
Dr. Sahar Yousef 坚定地回答：“The mission I am on, is to first and foremost, bring science education to the world, in a way that allows people to work more in line with how their brains and their bodies actually work best.” 她将大脑和身体的运转方式类比为物理学定律：人们永远不会在清晨醒来时试图对抗或废除重力，因为重力是客观的物理法则。然而在日常生活中，人们却一直在盲目、无知地违背自身的生物学规律。
在现行教育体系与企业职场中，几乎没有人系统性地教导儿童或职场人士大脑是如何运作的——如何更容易进入心流状态、如何管理生理压力、以及睡眠的底层机理。整个社会都陷入对交付物和目标的畸形痴迷中，年复一年地追问“做什么（What）”——年度目标是什么、季度目标是什么、交付物是什么——却从不探讨“怎么做（How）”。Dr. Sahar Yousef 强调，尤其是在推崇创新的硅谷，所有人都在谈论创新，但创新的生理载体正是人类的大脑。忽视这个生物系统的运作机理，导致了现代人工作与生活之间巨大的摩擦与内耗，而科技的滥用正在加剧这种冲突。

### [05:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=300s) 脑雾、自我失联与“超人实验室”
当被问及大众在向她求助时最常挂在嘴边的痛点是什么时，Dr. Sahar Yousef 脱口而出的是“脑雾（Brain Fog）”。她回忆起曾辅导过的一位女性首席执行官，对方在调整后感慨道：“我终于又能听见自己内心的想法了。”这句话给 Dr. Sahar Yousef 留下了极其深刻的震撼。现代人陷入了一种对“与自己独处”的普遍恐慌与不适之中，在工作、会议和通话的每一个微小间隙，全都被无休止的刷手机和信息摄入填满。当大脑完全处于被动消耗状态时，它根本没有空间产生属于自己的灵感与思考。
Dr. Sahar Yousef 介绍，自己的全部学术生涯均在加利福尼亚大学伯克利分校（UC Berkeley）度过，研究专长是认知神经可塑性（Cognitive Neuroplasticity）。由于神经可塑性意味着大脑时刻都在改变、进化与重塑，她创立了“Becoming Superhuman Lab”（成为超人实验室）。该实验室的核心宗旨，就是通过调高个体的注意力广度、记忆力以及流体智力等认知指标，帮助人们“用最少的时间、最小的压力，完成最多的事情”。
为了让理论落地，她曾深入企业一线进行深度田野观察。她曾受聘入驻一家《财富》世界 10 强（Fortune 10）的科技巨头，全天候贴身观察其最高层管理者的日常：
- 观察对象甚至包括高管一天中的饮食饮水、休息频率、开会互动以及工作流细节。
- 随后基于神经科学数据对其整体工作习惯进行全面改造（overhaul）。
- 她清晰记得一次标志性的转折点：该高管身处开放办公区正中央的全透明“玻璃盒子”办公室里，管理着数十亿美元的业务，正在赶制一份至关重要的董事会汇报 PPT。
- 然而，即便是在做极其重大的商业决策时，该高管不仅要暴露在全员可见的透明空间中，桌面上还并排摆放着两台显示器（副屏大敞着电子邮箱）、两部正面向上的手机（一部个人用、一部工作用），手腕上还戴着不断震动提示的 Apple Watch。这种环境让大脑完全暴露在无休止的干扰风暴中。
### [10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=600s) 数字卫生与“先成为正常人类”
现代知识工作者的办公日常充满了无休止的打扰。Sahar Yousef 博士生动地模拟了一个专心工作的场景：一个人刚坐下来准备聚焦，耳边立刻响起各种各样的提示音——“哔哔、咚、叮、噗、啪”，周围人来人往，幕僚长还时不时推门进来提醒别忘了某件事。在这样的工作状态下，一个人能保持专注的时间可能只有 30 秒。相关研究表明，知识工作者在被另一个屏幕或通知打断前，在单一屏幕上保持专注的平均时间仅有 47 秒。
为了说明这种工作环境的荒谬，Yousef 博士打了一个比方：如果有人给你 10 亿美元去攻克癌症，并让你召集全球最顶尖的头脑，你会给这些顶尖科学家配上一块满是通知的 Apple Watch、装满未读消息的 Slack，再把他们的日程塞满会议和电话，然后指望他们在几年内攻克绝症吗？显然不会。人们会为他们打造一个完全不被干扰的环境，保护他们最宝贵的深度思考能力，而不是让他们一早醒来就疲于应付各种电话与碎片的琐事。
Yousef 博士笑称，自己明明研究的是极其复杂的高精尖神经科学，现实中却总在与人讨论最基础的日常习惯，这既讽刺又真实。在奢望“成为超人”之前，现代人首先要学会“成为一个正常的人类”。她将这一过程称为“数字卫生”（Digital Hygiene）——清理掉阻碍生产力、专注力与人体生物学规律的障碍，遵循最基础的人体运行机理。
- 知识工作者在受到外界或另一屏幕干扰前，在单一屏幕上的平均注意力持续时间仅为 47 秒。
- 博士强调，解决问题的第一步不是追求极端技巧，而是认识并尊重人体生物学规律，彻底清除干扰环境的杂物。

### [11:55](https://www.youtube.com/watch?v=yePLuwL3FbM&t=715s) 现场工坊公告与生产力基石：睡眠
Steven Bartlett 针对听众经常反馈的“听了很多健康与生产力理论却不知如何落实”的痛点，宣布与 Yousef 博士合作举办一场 DOAC 史上首次的互动直播工坊（DOAC Workshop），旨在将节目中的神经科学洞察转化为观众能立刻付诸实践的行动工具。
回到具体方案的讨论上，Steven 询问若想做出卓越的工作成果、保持敏锐思考和创新，推倒整张骨牌的第一块基石是什么。Yousef 博士毫不犹豫地指出了睡眠。她见过太多精疲力竭、拼命苦熬的创始人和 CEO 跑来问她“怎样才能让我再提升 1%”，而一查他们的睡眠，平均每晚只有 5 个小时。
Yousef 博士给出了一个生动的比喻：“这就好比你把车开进修车厂，我作为修车工一看，整辆车都在着火，而你坐在里面毫无察觉，还探出头问我：‘能把我的引擎改得更猛一点吗？’我会说：‘老兄，我们得先灭火，我现在甚至都无法评估你原本的基线性能。’”
- 认知表现与情绪调节的绝对生理底线是每晚至少 7 小时的充足睡眠。
- 长期缺乏睡眠不仅摧毁认知系统，还会引发情绪失调，导致在职场和人际交往中变得极度易怒、焦躁。
---
### [15:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=900s) 手机保险盒与“注意力即记忆”
如果说睡眠是生理基石，那么影响现代人认知表现的第二大全球性危机，就是人与技术之间的关系。Yousef 博士带来了一个物理道具——手机定时锁盒（Phone Lockbox），甚至现场让 Steven 将手机关机并锁入其中。虽然并不是每个人都必须购买锁盒，但它的核心寓意在于：大脑本质上是一台“单任务聚焦机器”，必须通过物理或数字屏障来获得单核聚焦的能力。
在神经科学中，专注力、记忆与学习是完全无法割裂的同一件事。Yousef 博士指出：“你不可能记住任何你未曾倾注注意力的事情。”进入人们注意力光圈（Aperture of Attention）的内容，才构成了意识与长期记忆。没有专注，记忆和学习就无从谈起。然而，自智能手机普及以来，人类维持持续注意力的能力正在呈线性下滑；如果一个人整天盯着收件箱并随时待命，他绝不可能产生任何有深度的思考。
面对 Steven 提出的普遍担忧——“如果万一有紧急大事发生怎么办？比如未婚妻被锁在门外或突发商业危机”，Yousef 博士用传统邮政系统进行类比。极度重要的包裹需要快递员亲自敲门并要求收件人当面签字；只有这种真正十万火急的事件才配称为“敲门签字的 VIP 级通知”，而其他绝大多数普通信件，只需统一塞进邮箱、集中批处理即可。
- 记忆与学习的前提是专注；注意力光圈之外的信息无法在大脑中形成有效记忆。
- 应对“紧急事件焦虑”的科学策略是建立 VIP 过滤机制：仅保留极少数生死攸关级别的物理/数字提醒，其余杂讯全部延迟处理。

### [18:25](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1105s) 商业软件的绑架机制与反抗默认设置
现代数字设备为何会让人无法自拔？Yousef 博士揭露了技术设计背后的残酷真相：无论是手机操作系统还是看似枯燥的生产力软件，其底层默认设置都是由认知神经科学家与行为神经科学家专门设计来“套牢”（Hooked）用户的。
很多人误以为只有 TikTok 等娱乐社交软件才会争夺眼球，但事实上面向企业客户的基础软件（如 Microsoft Outlook、Slack、各类办公通信协同平台）同样深陷于留存与续约逻辑之中。这类 SaaS 软件在面对企业客户的年度续约谈判时，必须拿出一份漂亮的高活跃度数据报告，证明“所有员工每天 24 小时都在高度使用并互相通信”。因此，它们在产品设计上就会无所不用其极地推高参与度（Engagement），用各种即时弹窗和未读红点绑架打工人的大脑。
正因如此，科技巨头出厂自带的所有“默认设置”从来都不是为了保护使用者的专注力和身心健康，而是为了服务于平台的商业留存。Yousef 博士因此呼吁：“我们都足够聪明，也应当给予自己足够的尊重，去主动要求并设定优于出厂默认设置的数字环境。”
> “我们所有技术、应用、电子邮件以及手机的出厂默认设置，都是由像我这样的认知神经科学家和行为神经科学家设计的，其目的就是为了让你上瘾。” —— Dr. Sahar Yousef
### [20:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1200s) 默认设置的陷阱：生产力工具的底层商业动机
Sahar Yousef 博士指出，团队日常使用的各类电子邮件及通讯软件，其所有出厂默认设置的核心目的只有一个——最大化用户参与度（Engagement），而不是为了提升公司或个人的生产力。这些商业软件的开发商根本不在乎使用者的实际产出，那属于用户自己的课题。Sahar 博士用糖果公司作了一个生动的类比：正如一家巧克力制造厂的根本利润诉求是尽可能多地卖出糖果，它们并不会主动为消费者是否会患上糖尿病或是否摄入过量承担责任；数字通讯平台同样如此，用户的时间与注意力参与度就是它们的货币。从邮件发出时那声经过精密测试的清脆提示音，到手机内置的震动反馈频率，全都是由行为与神经科学专家反复调试打磨出的产物，目的就是为了激发人脑的奖赏回路，让用户对设备欲罢不能。
Steven Bartlett 对此深有共鸣并补充道，这些软件向投资人汇报业绩时，核心指标永远是用户的活跃时长与互动频率，这与工具宣称要“消除干扰、提高效率”的初衷在逻辑上完全背道而驰。Slack 等工具表面上宣称能让团队工作更出色，实质上却在不断制造打扰。Sahar 博士坦言，自己每次听到这些产品自称“生产力软件”都会冷笑，尽管现代团队跨时区协作确实离不开技术，但大众必须破除盲信。她强调自己绝非技术排斥者（Luddite），而是倡导每位知识工作者都必须建立一种清醒的心态。Sahar Yousef 博士严肃地总结道：“默认设置的存在根本不是为了帮助你，每个人都应该告诫自己：我配得上比默认设置更好的工作状态。”

### [22:21](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1341s) 夺回控制权：VIP 通知清单与邮件过滤法则
面对 Steven 坦白自己每天查看手机长达 10 小时、且时刻担忧遗漏突发紧急事件（救火心态）的现状，Sahar 博士给出了首要实操对策：在所有设备与通讯工具中配置“VIP 通知清单”。建立此机制的核心在于明确哪些人有权击穿你的防御壁垒：通常只包括伴侣、直属领导及其上级，以及面向客户岗位中的前 15 位核心重要客户。只有当这些特定联系人来电或发信息时，系统才会突破静音过滤进行强提醒，其余一切常规动态均应静默化处理。
在电子邮件管理方面，Sahar 博士分享了自己的一项专属规则：她在邮箱后台设置了包含自己名字在内的 3 个核心关键词过滤。由于她的名字较为少见，只要邮件正文直接提到了她，系统才会推送；而在日常绝大多数职场场景中，人们往往只是被动抄送（CC）在多人群聊或邮件链条中，看着同事彼此讨论方案。Sahar 博士指出，领导者与核心贡献者的职责是专注于战略思考与推进工作，而不是在团队成员自行解决问题时，每一次互动都跳出来打断思路。
- **VIP 清单划定范围**：伴侣、核心家庭成员、直接上司及其上级领导、业务层面最关键的前 15 位重要客户。
- **免打扰防线穿透**：仅允许 VIP 名单的通话与信息绕过勿扰模式，其余通知一律转为异步批处理。
- **邮件定向关键词规则**：通过定制名字或关键项目代码过滤抄送邮件链，阻断无意义的认知干扰。
### [24:52](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1492s) 拒绝的艺术：默认“拒绝”与应对取悦症
Steven 提到，职场中存在巨大的社会压力促使人们秒回信息、答应参会和承揽事项，稍有延迟便担心被视作无礼，因此高度专注的人往往需要克服“讨好型人格”（People-pleasing）。当被问及身边谁是专注力最强的人时，Sahar 博士坦言第一反应是自己的丈夫。他们共同创立并管理公司，两人恰好形成了鲜明的互补：Sahar 博士的本能倾向是“默认答应”（Default Yes），热衷于探索各种闪闪发光的新机会；而她丈夫的本能则是极其坚决的“默认拒绝”（Default No），视时间和注意力为生命中最宝贵且不可再生的资产。
每当团队面临新议题时，两人都会展开激烈的思维碰撞。Sahar 博士提到，她丈夫常说的一句话是，缺席某场会议或许在当下会令少数人感到失望，但时间会证明，自己在该会议中的边际贡献本就微乎其微，团队离开他依然能顺畅运转；而省下来的整块时间，却能让他沉下心完成真正关乎整个工作生态的重大构想与核心产出。正是这种对自身认知资源的严防死守，才构筑了顶尖的专注力。
### [25:48](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1548s) 信号与噪声：乔布斯、马斯克与极致专注的真谛
讨论由此延伸到“信号与噪声”（Signal vs. Noise）的经典法则。Steven 回忆起此前采访著名投资人 Kevin O'Leary 时的对话。Kevin 曾与史蒂夫·乔布斯（Steve Jobs）以及埃隆·马斯克（Elon Musk）深入合作，他观察到乔布斯拥有一种惊人的 80/20 信号识别能力，在面对冗长讨论时总会一针见血地打断：“我们为什么要讨论这个？眼前这件才是最重要的事。”Kevin 更直言，在他漫长的职业生涯中，唯一在专注力上比乔布斯还要极致强悍的人就是埃隆·马斯克。
Steven 接着援引了传奇设计师 Jony Ive 对乔布斯的评价。Jony Ive 曾指出，大众常常误解了专注的本质，以为专注仅仅是从两件事中挑选一件去做；但真正的专注是，哪怕你在清晨醒来时脑中涌现出一个极其绝妙的想法，你的每一根骨头都在叫嚣着渴望去实现它，你依然能够冷酷地对它说“不”。乔布斯常常会走到 Jony Ive 面前盘问他当天拒绝了什么，甚至能一眼识破 Jony 拿那些本身就不感兴趣的事项充当“牺牲品”，并进一步逼问他到底放弃了哪些自己发自内心认为极具价值的项目。两位对话者达成共识：想要达到 80/20 的境界，比起极其费力地去“增强信号”，普通人第一步且最有效的方式就是“降低噪声”——把生活与工作中的干扰彻底清除。
### [28:02](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1682s) 人脑是单任务机器：进化的超警戒机制与开放式办公的灾难
针对现代职场普遍将“多任务处理”（Multitasking）与“上下文切换”（Context switching）标榜为核心能力的错觉，Sahar 博士从认知神经科学层面予以了彻底驳斥，指出人类大脑在本质上就是一台纯粹的“单任务运转机器”（Monotasking machine）。从进化生物学的角度来看，人类在自然界中处于身体机能的弱势地位，既没有猛兽般锋利的爪牙，也没有绝对的力量优势，能够站在食物链顶端完全依赖于大脑的策略规划、抽象思考与高度专注能力。
与此同时，这种生存导向的生理构造也带来了现代环境下的适应不良。Sahar 博士指出，人类大脑皮层中有大约整整三分之一的区域（Cortical real estate）专门用于视觉和听觉的信息处理。这种底层神经布线使人类时刻对周边风吹草动保持“超警戒状态”（Hypervigilant），以便及时觉察潜藏的天敌。在远古时代这是保命的绝技，但在当代典型的开放式办公环境（Open-plan office）中，这一机制却沦为了专注力的灾难。正如高管坐在透明的玻璃盒办公室里，四周人流穿梭不息、杂音不断，视觉与听觉皮层不断被迫响应这些无害的环境刺激，使得神经系统在寻找“信号”的过程中被海量的“噪声”彻底消耗殆尽。
### [30:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1800s) 逃避不适感：大脑为何主动向分心投降
人类文明正被随处可见的干扰严重阻碍。Dr. Sahar Yousef 感叹道：“我希望我们这个物种继续进步，而且要以人类可能达到的最快速度前进。我知道我们有这个能力，但人类目前所有的才智全都被这些干扰给吸干了。”Steven Bartlett 随即分析，干扰找上门来通常有两种路径：一种是被动的外部侵入，比如手机提示音响起或 Apple Watch 开始震动；另一种则是主动寻求转移——当我们写论文或做某项工作正卡壳、遇到棘手或令人不适的难关时，就会下意识抓起手机，在 WhatsApp 群聊里热烈讨论周末的安排。尽管 Steven Bartlett 关掉了绝大部分应用通知，却依然发现自己每分钟都在不受控地伸手去摸手机。

Dr. Sahar Yousef 从脑科学的角度给出了底层解释：大脑本质上是一台“问题解决机器”。由于根植于基因中的生物法则，人类普遍具有“逃避不适感”的强烈倾向。这里的不适感包括不知所措、压力、焦虑、困惑、轻度抑郁、错失恐惧（FOMO）、孤独、愤怒或挫败感。Dr. Sahar Yousef 强调，大脑是站在你这一边的，它和你都不想忍受这些负面情绪。当人在庞杂的任务面前感到不知所措时，脑内机制会立刻发问：“怎么才能避开这个鬼东西？”面对这种压力，解决路径只有两条：要么硬着头皮正面攻克，但这需要耗费极大的精力和心力；要么采取“情感逃避”（Emotional Avoidance）。在现代社会，最快、最廉价的避难所就是 TikTok、Shake Shack 快餐和色情内容——这些刺激能瞬间让人陷入麻木。正如 Dr. Sahar Yousef 所言：“手机为我们创造了一个出口，一个通往现实之外、极度快速且廉价的出口。”
- 人类大脑的设计初衷是保护机体免受痛苦，因此会将情绪逃避视为比死磕难题更经济的“减负方案”。
- 承认并正视逃避冲动的普遍性，是学会摆脱数字依赖、夺回注意力的第一步。

### [32:35](https://www.youtube.com/watch?v=yePLuwL3FbM&t=1955s) 宁可电击也不愿独处：科技巨头对大脑的劫持
为了说明现代人有多惧怕与自我独处，Steven Bartlett 提到了一个著名的心理学实验：受试者在实验前先体验了一次微弱电击，且大多数人平均表示哪怕花钱也不愿再被电击一次；然而，当他们被单独关在一个空无一物的房间里被要求静坐时，房间内唯一可操作的只有一枚能引发电击的按钮。结果出人意料，许多受试者在孤独枯燥中不断按下按钮电击自己，其中男性的频率显著高于女性，甚至有一名受试者在独处期间按下了几百次电击。该实验得出结论：当代人宁可自讨苦吃遭受电击，也不愿独自坐着面对沉寂。Steven Bartlett 坦诚剖析自己：“当我的手机没电关机时，老实说——我觉得没必要去装模作样伪装成别人——我会产生一种轻微的焦虑感，我绝对是对手机上瘾了。”他估计自己每天至少要拿起手机查看 200 次。
在进入深度工作前，移走手机、关闭通知固然是基础操作，但背后的大脑成瘾机制远比这险恶。Dr. Sahar Yousef 指出，科技巨头为了劫持大脑并诱导成瘾，其手段与食品工业用精制糖和超加工食品让人上瘾的商业套路如出一辙。她归纳出食品巨头成功奴役人类味蕾的三步法模型：
1. **大幅增加感官刺激（Increase the stimulation）：** 远古时代食物极度匮乏，人类演化出了本能迷恋高能量标志物（糖、盐、脂肪）的基因。食品工业利用这一点，在任何可能的地方疯狂注入糖分。在美国，即使买一条普通无甜味的吐司面包，背面配料表也全都有糖。
2. **极力降低获取门槛（Decrease the friction）：** 将加工食品装入精美诱人的独立小包装，大力普及随处可见、即买即食的快餐，彻底抹杀自己下厨做饭的繁琐流程。
3. **刻意剥离饱腹感成分（Decrease the satiation）：** 人体吃饱依赖蛋白质与膳食纤维，而超加工食品和糖果几乎将这两样剔除殆尽，导致大脑永远处于“没吃饱、想继续摄取”的虚假饥饿循环中。
---
### [35:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2100s) 间歇性可变奖励：信息流算法的毒性操纵术
Dr. Sahar Yousef 揭示，数字科技公司把食品工业的这套剧本复刻得淋漓尽致，精准狙击了人类的视神经与心理弱点。首先是“极致提升视觉刺激”：手机图标的色彩饱和度被调至极高，屏幕散发出高频光线，直接轰击占人类大脑皮层很大比重的枕叶视觉皮层（Occipital Lobe）。“这就像进了赌场一样，你从没见过哪家赌场采用中性冷淡色调吧？里面到处都是晃眼的色彩和闪烁的灯光。”短视频（Reels 和 TikTok）则用极高密度的快节奏让视线无法移开。
更为致命的是算法对“间歇性可变奖励”（Intermittent Variable Rewards）的深度运用。Steven Bartlett 回忆起自己 16 岁在心理学课上学到的斯金纳鸽子实验：生物对固定不变的奖赏很快会失去兴致，却对不可预测、时有时无的随机反馈极易陷入深度沉迷。Dr. Sahar Yousef 将其形容为毒性恋爱关系中的“爱意轰炸”（Love Bombing）套路——先是冷暴力、人间蒸发，接着突然施以狂热的温存，让对方彻底深陷其中。

```
信息流算法正是以这种机制来收割用户的：平台算法其实极其了解用户的偏好，后台甚至为每一个人储备了专属的“宝藏内容库”。但当你刚刚打开应用时，算法绝不会直接奉上那些你最想看的精华——因为你刚刚坐下，有的是时间与精力，此时推送太好属于“赔本买卖”。它会先向你推送中规中矩甚至平淡无奇的平庸内容，借此试探你的耐心。系统精准计算着每个人的注意力极限，就在你感到无聊、正准备按退出键的一瞬间，算法会啪地一声甩出一个超级大奖——比如一个让你毫无抵抗力的 Steven Bartlett 精彩访谈切片。用户瞬间产生“天啊，幸好刚才没划走，这期太棒了”的心理错觉，进而被牢牢锁死在无休止的下滑深渊中。
- 视觉皮层占据了人类大脑皮层极大的空间，高饱和度界面配合屏幕背光，在神经层面上能够产生类似拉斯维加斯老虎机的持续诱惑。
- 间歇性可变奖励的本质在于“人类知道奖励迟早会来，但永远猜不到会在哪一次出现”，这种不确定性所引发的多巴胺分泌远超固定奖励。
### [40:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2400s) 老虎机机制、无限滚动与数字“垃圾热量”
Dr. Sahar Yousef 解释说，如果一个平台连续五个小时向你展示每一条你确定想看的内容，你反而不太容易上瘾。人类大脑沉迷的本质是不确定性与随机刺激：“这就像赌场和老虎机的运作方式，这全是一套计算机程序和数学算法。他们希望你输掉一大笔钱陷入亏损，然后让你赢回一块五毛钱，让你觉得‘我又杀回来了’。”推荐算法正是以这种机制提升神经刺激强度。
除了提高刺激，科技平台还彻底削减了获取内容的摩擦力。早期互联网、YouTube 或 Instagram 有着天然的“刹车止损点（backstop）”或分页浏览（pagination），用户只能看到自己主动订阅或关注的内容，刷完便会见底。而现代平台发明了“无限滚动（infinite scroll）”机制。Dr. Yousef 打了个生动的比方：“无限滚动就像你去吃自助餐，直接张大嘴巴，前面是一整条流水线源源不断地把食物和糖果往你嘴里倒，完全没有刹车片。”
更严峻的问题在于，这些平台大幅削减了“饱腹感（satiation）”。人类对社交连接与归属感有着类似于进食的基本生物学需求。然而，社交媒体制造的只是连接的假象：
- 数据表明，一个人在这些平台上花费的时间越长，内心反而越感到孤独。
- 当人们独自在家感到孤独、焦虑和错失恐惧（FOMO）时，最快、最廉价的应对方式就是抓起手机。
- 这种行为就像在极度饥饿时狂吃彩虹糖（Skittles）。糖果虽然含有热量，但不仅不能提供真正的营养，反而会导致血糖瞬间飙升后剧烈崩溃。Steven Bartlett 对此总结道：“如果我摄入了这些垃圾热量，六个小时后我又会回头去寻找更多的垃圾热量。”
短视频平台同样利用了人类对“新奇感与学习”的生存进化本能。虽然短视频让人产生在几秒内学到冷知识的幻觉，但退出应用后大脑根本记不住任何东西。相比之下，耗时数小时的长篇播客虽然门槛更高，却能真正带来认知饱腹感。

### [45:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2700s) 逆向神经科学与“灰度模式”实验
针对大科技公司利用神经科学操控注意力的现状，Dr. Yousef 提出了“逆向神经科学（Reverse Uno）”策略：如果系统通过增强刺激来诱捕大脑，用户就必须主动降低外界刺激。她指出，智能手机出厂时的默认设置并不是为了帮助用户，而是为了从用户的注意力和时间中牟利。
最立竿见影的干预措施是将手机屏幕显示设为“灰度模式（grayscale）”：
- 去除鲜艳色彩后，手机在神经层面上对大脑的刺激会骤降，视觉上显得“了无生趣（looks dead）”，从而极大降低在深夜意志力薄弱时盲目刷屏、反复在各类应用间切换的冲动。
- Dr. Yousef 宣布：“你比默认设置更强大，Steven。我比默认设置更强大。每一个正在收听这期节目的人，你们都比默认设置更强大。打破默认设置，把你的手机调成灰度。”
- 针对 Steven Bartlett 提出的这一方法是否有实证数据支撑的疑问，Dr. Yousef 透露了其实验室的研究成果：在对大样本健康职场专业人士进行测试时，团队仅要求他们将手机屏幕调为灰色并保持三周时间，结果显示“受试者平均每天看手机的时间整整减少了一小时”。每天省下一小时，意味着每周凭空赢回七小时，这足以支撑起一周规律的健身运动或阅读计划。

### [48:30](https://www.youtube.com/watch?v=yePLuwL3FbM&t=2910s) 长内容保护同理心与当代的注意力退化危机
Dr. Yousef 提出的第二条策略是以长篇内容（long form）替代短内容（short form）。研究表明，看一部完整的高质量电影能够切实增强年轻人的同理心与共情能力。她明确澄清自己并不主张“所有屏幕时间都是罪恶的”，而是倡导一种健康的“内容饮食结构（content diet）”：想看电影就穿上睡衣、爆好爆米花、调暗灯光，全神贯注地享受。
然而，当代人普遍的观影状态是电视上放着 Netflix，手里还捧着手机刷个不停。内容制作方甚至不得不预设观众在分心状态下来制作视频。Dr. Yousef 痛心地指出：
> “如果你连看一部他妈的电影都无法集中注意力了，你还怎么可能体验到自己心智的全部潜能？”
Steven Bartlett 深有感触地分享了前一晚的经历：他在看一部复杂的经典老电影，片中把一个星球命名为“Kololubulu”，如果漏听了一个词，接下来的三个小时就会完全摸不着头脑。他回忆起童年时全家人坐在沙发上一动不动专注盯着荧幕的场景，对比之下，他发现自己在观影时必须耗费极大的心理力量去抵抗看手机的冲动，现代生活方式与深度内容之间已经出现了巨大的错位。
Dr. Yousef 警告那些以“我就是喜欢看短视频”为借口的人，过度依赖短形式内容已经被证明会导致抑郁、焦虑以及注意力跨度彻底崩塌：“你不仅主观感受会变得极差，你的大脑运转水平也会被硬生生拉低。”
### [50:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3000s) 真实社交连接与“令人后悔的分秒”
Sahar Yousef 博士强调，从认知角度来看，过度消费短视频和碎片化内容是个人选择，但人们必须认清大脑背后存在根本的生理和心理需求。短视频之所以让人上瘾，是因为人们误以为它能带来连接，但真正能够满足社交与求知渴望的，是现实生活（IRL）中的真实互动。
Sahar Yousef 博士呼吁大家：“去拥抱他人、触碰他人、与人面对面交谈、举办晚宴、与朋友和家人相聚，真正满足对社交连接的基本渴望。”当你真正感到充实时，你会神奇地发现自己对短视频的渴望大幅减少，不再容易在半夜两点无休止地刷手机，次日醒来也不会因睡眠匮乏而感到糟糕透顶。
Steven Bartlett 对此深有共鸣，并借用了推特前首席执行官 Jack Dorsey 曾提及的核心指标——减少“令人后悔的分秒”（regrettable minutes）。Steven 拿彩虹糖（Skittles）打比方：吃糖的当下感觉极好，但如果吃下一大包，几个小时甚至次日就会让人非常后悔。短视频也是同样的道理。根据数据，约 60% 的 TikTok 活跃用户承受着负面情绪，甚至希望这个平台从未存在过。TikTok 在“令人后悔”排行榜上位居第一，许多人反馈打开应用后时间被扭曲，平白流失了一两个小时，退出时却完全不知道自己收获了什么。

### [52:45](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3165s) 手机成瘾的“分量控制”与戒断法则
现实生活中人们越发孤单，商业平台便利用这种持续的“饥饿感”，将用户死死锁在分心循环之中。如今在社会交往中，无时无刻拿着手机或装在口袋里已被视为常态。Sahar Yousef 博士提出，解决这一困境的关键手段是“分量控制”（portion control）和增加阻力（friction）。
“分量控制”并不意味着直接戒除手机，而是打破即时唾手可得的状态。Sahar 博士指出，关闭通知是降低环境刺激，而增加物理阻力则是核心：例如设立“手机停车场”（phone parking lot），将手机放在视线之外的地方。如果明知某种东西极易成瘾却依旧随身携带，就像坐在一个刚开始戒酒的酒精依赖者面前并问：“你不介意我在你面前放杯啤酒吧？”
Steven Bartlett 赞同道，他绝不会在兜里随时揣一包彩虹糖，否则一旦感到无聊或压力，就会忍不住去抓来吃。Sahar 博士表示，这套认知方法应当在学校里全面普及，许多疲惫的父母在家里总是扮演“坏警察”的角色，整天冲着孩子喊“离手机远点”，这种对抗亟需通过科学的方法来化解。

- **LinkedIn Hiring Pro**：Steven 强调，初创企业面临的最大威胁往往不是产品缺陷，而是招聘错误——糟糕的雇佣会迅速摧毁公司文化并给增长踩下刹车。该工具利用 AI 驱动的面试和自动化流程帮助筛选候选人，约 60% 的使用者在一周内即可敲定面试人选。
### [56:45](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3405s) 专注冲刺（Focus Sprint）步骤一：预先时间封锁与生理准备
面对现代职场中海量的代码编写、深度写作与内容打磨需求，Steven 向 Sahar 博士询问，在充满干扰的环境下究竟该如何可靠、可预测地完成深度工作。Sahar Yousef 博士提出了其实验室经过科学实证的核心工作法——“专注冲刺”（Focus Sprint）。
Sahar 博士指出：“根据我们实验室的研究，专注冲刺法能让人完成高达平时两倍的工作量，同时减少错误率，并且让你感觉更好。”这套方法共有五个步骤，其核心逻辑在于顺应大脑和身体的生物运作节律，消除认知阻力。
```mermaid

end
```
第一步是在日历中提前留出专门的时间块（例如 1 小时）。其背后的神经学机制是利用大脑和身体的“前瞻网络”（anticipatory networks）。就如同人在公开发言或重大演讲前会感到心跳加速、手心出汗一样，即使身体处于静止状态，大脑在预知挑战来临时也会提前释放适量的皮质醇和肾上腺素。这种适度的生理唤醒能让人在正式坐下来时迅速进入高专注、高能量状态。此外，在团队协作中，将专注冲刺在公开日历中标注出来，能有效消除“必须即刻秒回消息”的社交负罪感。
### [59:15](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3555s) 专注冲刺（Focus Sprint）步骤二：任务原子化切片与多巴胺激励
第二步是明确定义冲刺期间的具体行动，并将其拆解为极其具体、可操作的单元。绝不能模糊地说“我要去处理项目 X”，除非你有把握在这一个小时内彻底完工，否则模糊的目标只会带来挫败感。
这背后的关键分子是多巴胺（dopamine）。多巴胺不仅是大脑的动机驱动剂，让人对任务产生兴奋感，还负责在取得预期之外的进展时提供神经奖赏。Sahar 博士建议：
- 从庞大的待办事项清单中进行“单项选购”，只挑出一件事作为冲刺对象；
- 避免模糊的宏大叙事（如“我要改 PPT 胶片”），而是将其彻底原子化；
- 将具体微小任务与时间严格绑定，例如精确设定为：“在接下来的时间块里，我只攻克第 3 页 PPT”。
### [01:00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3600s) 聚焦冲刺：将产出拆解为执行清单
Dr. Sahar Yousef 强调，在进入聚焦冲刺（Focus Sprint）之前，必须将目标细化为颗粒度极细的“执行清单”（execution list）。例如，“花大约 7 分钟完成那张 PPT 幻灯片，接着发邮件跟进 John 获取第 17 页所需的数据，随后制作要插入的表格”。这种将任务具体拆解的方法，能够有效刺激多巴胺分泌，让人产生把事情做完的渴望。

Steven Bartlett 对此深有共鸣，指出许多人常把目标定为“投入”而非“产出”——大家常说“我要研究一下这个”或“我要就此思考规划”，却没设定具体的产出成果。Dr. Sahar Yousef 解释，如果缺乏一份事先排好的清单，大脑在做完第一步后就会茫然停下，四处张望并思考“接下来该做什么”。而一旦在冲刺过程中停下来做决策，注意力就会瞬间涣散。
> “我不希望你在比赛正酣的时候，才开始琢磨这游戏到底该怎么玩；我们得先把这场仗怎么打规划清楚，然后再一头扎进去说‘冲刺吧’，然后一路狂飙到底。” —— Dr. Sahar Yousef
因此，聚焦冲刺的核心机制在于：
- **目标必须是明确的“产出”（Output）**：绝非模糊的“投入”（Input）或泛泛的“努力”。
- **提前锁定时间并同步团队**：让周围人知道你在闭关，调动体内的预期网络与激素。
- **杜绝比赛中途定规则**：将每一步的耗时精细化排布，进入状态后像机器一样纯粹执行。

### [01:01:44](https://www.youtube.com/watch?v=yePLuwL3FbM&t=3704s) 待办清单的“冰箱法则”与 MIT vs. LIT
面对庞大而混乱的待办清单，Dr. Sahar Yousef 提出了“冰箱法则”：对待大型待办事项，要像对待自家的冰箱、食品储藏室和冰柜一样。冰箱里有些东西属于“定时炸弹”，比如解冻中的鸡肉，若不立即处理就会变质。每天早晨，每个人都该打开这个“冰箱”，首先审视自己当天究竟有多少可用时间。如果能腾出 3 个小时无打扰的深度时间，那已经是非常美妙的一天。
接着，在可用时间内挑选出 **MIT（Most Important Tasks，最重要任务）**。这是 Dr. Sahar Yousef 实验室的核心概念：
- **MIT（最重要任务）**：每天挑选 1 到至多 3 件任务。只要搞定它们，这一天就是成功的。衡量标准很简单：“未来的你是否会感谢现在的自己做出了这个选择？”
- **LIT（Least Important Tasks，最不重要任务）**：类似于在 DocuSign 上签个字、回复一封水邮件、在亚马逊上下单买卫生纸等琐事。
Steven Bartlett 指出，人们天生抗拒那些超出舒适区的硬仗（如复杂的财务、投资或运营），反而倾向于冲向轻松的 LIT，只为享受在清单上“划掉一勾”的快感。Dr. Sahar Yousef 将 LIT 称为“快多巴胺（Fast Dopamine）”，而真正能推动公司与人生跨越式发展的，绝大多数是右侧那些带来“慢多巴胺（Slow Dopamine）”的 MIT。她并不主张彻底抛弃 LIT，而是建议将完整的高效时段留给 MIT，利用会议间隙的 15 分钟边角料时间去集中清空 LIT。

当面对清单上动辄六七十个待办事项、不知道哪个才是真正的 MIT 时，Dr. Sahar Yousef 建议从宏观的视角进行复盘：认清自己未来五年的长期目标到底是什么，找到自己的“珠峰（Everest）”。如果你的珠峰在前方，你就绝不可能朝后走，否则每一步都充满偏航与危险。
> “我非常热衷于谈论死亡，因为我觉得死亡能把一切都梳理得清清楚楚。在我看来，最好的认知框架，就是真正想象自己躺在临终床上的模样。” —— Dr. Sahar Yousef
Dr. Sahar Yousef 引导现场做了一个思维实验：假设在现代长寿医学与科技助力下，你活到了 110 岁的高龄。当你躺在病床上回首一生，你需要经历过什么、达成过什么、做成过什么，才能心满意足地微笑着说一句“这辈子真值，我过得棒极了，我完成了想做的一切，可以坦然面对下一程了”？
面对这道灵魂提问，两人探讨了临终时刻真正沉淀下来的东西：
- **Steven Bartlett 的临终图景**：他闭上双眼后，首先看到的是房间里有谁——他的爱人以及围绕在病床前的孩子们。他希望孩子们眼中的父亲不仅是他们人生的榜样（证明人可以实现伟大的事情），更是为地球留下了净正面资产（Net Positive）的奉献者。
- **仆人式领导与使命感**：Steven 坦承自己对“改善人类系统”有着极深的执念，甚至为此牺牲了大量所谓的个人享乐。
- **彻底剔除噪音（“去他的彩虹糖”）**：一旦确立了这种终极的人生方向，生活中的无意义诱惑立刻原形毕露。从来没有任何一个人会在临终床榻前懊恼“要是当年能多刷点 Netflix、要是能多刷会儿社交媒体短视频就好了”。
- **临终关怀护士的洞察**：Dr. Sahar Yousef 提到了著名临终关怀护士 Bronnie Ware 的研究，那些陪伴无数临终者走完最后一程的经历，最能证明人在生命尽头真正在乎的到底是什么。
### [01:10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4200s) 临终的顿悟、意识的共舞与心流中的“自我消融”
Sahar Yousef 博士谈到了临终陪伴者（death doula）所见证的生命真相。当陪伴那些即将离世的人时，人们往往能获得极其震撼的心智澄明。临终关怀人员曾做过记录，询问临终者一生中最大的遗憾是什么，而在所有人当中，排在第一位的遗憾始终是：“我希望自己当时能过一种真正忠于自己的生活，而不是那么在乎别人的看法。”Sahar Yousef 指出，对于 Steven Bartlett 而言，归根结底重要的并不是家人对其成就或时间分配的看法，而是他自己的内心认知。更深刻的悖论在于，人类永远无法真正完全洞悉另一个人的想法；人赤条条来到这个世界，无论彼此多么相爱，最终也是独自走向死亡。婴儿出生时的第一声啼哭，正是因为感受到了分离与恐惧，从而本能地哭喊着寻求联结；人类一生都在追寻这种归属感与深度联结，但在意识层面，每个人都拥有独立且不断动态演变的主观意识。哪怕仅仅相隔一秒，人脑的意识状态都在迭代更新，就如同每过一秒，世上便出现了一个“Sahar 1.00000001”的新版本。
尽管人类在生物学上无法完全与他人的意识合二为一，但人际交往中确实存在某种意识高度契合的“探戈”时刻。Steven Bartlett 分享道，在录制播客时，他常与嘉宾对坐三四个小时，深入探讨对方的童年创伤与生命轨迹，彼此的意识会交织在一起，带来一种甚至带有灵性色彩的深度联结。Sahar Yousef 极为认同这一点，她认为这种深层连接的本质就是“心流”（Flow）：当两个人进入同频的能量共舞时，最关键的前提是“自我的消融”。
> “我认为两个人要产生那种共同的心流，那种充满能量的共舞，必须放下对自我的感知；在那样的时刻，自我必须消融，而当我们完全将自身迷失在这个‘我们’之中时，它确实消融了。”（Sahar Yousef）
当个体过度执着于自己的身份与自我认知时，就会不由自主地在意对方如何看待自己，时刻处于“我与他者”的对立中；唯有在真正沉浸的瞬间，“我”与“你”才会融合成不可分割的“我们”。Steven Bartlett 补充道，这种体验与工作中的深度心流完全相通——当一个人全神贯注投入工作时，三四个小时会在不知不觉中飞速流逝，时间仿佛彻底停滞。

### [01:14:40](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4480s) 奶酪碎屑策略：“慢慢来”（Polé Polé）与专注踏板而非领奖台
谈及如何将庞大的重要目标转化为具体执行，Sahar Yousef 提出将核心任务（MIT，Most Important Task）拆解为如同微小琐事（LIT，Least Important Task）一样容易上手的小步骤。她用神经科学中的多巴胺机制打了个生动比方：追逐低多巴胺的宏大任务，就像一只老鼠在迷宫深处看到了一整块巨大的奶酪，旅程漫长而痛苦；而高多巴胺的微小任务，则像沿途掉落的一块块微小奶酪碎屑，老鼠会觉得“吃下眼前这颗碎屑毫不费力”。实现终极目标的关键，并非一开始就硬啃大奶酪，而是将大奶酪切碎，均匀散布在迷宫的每一步，正如老子所言“千里之行，始于足下”。
为了进一步阐释这一理念，Sahar Yousef 分享了她丈夫攀登乞力马扎罗山的经历。在极其险峻的高海拔环境下，当地的夏尔巴向导（Sherpa）拥有惊人的体能，背负着沉重的行李在山道上健步如飞。向导们在整个登山过程中反复对队员们强调一句斯瓦希里语短语：“Polé polé”（意为“慢慢来，一步一步来”）。如果登山者只是一味抬头仰望遥不可及的乞力马扎罗顶峰，就很容易被绝望击溃；唯有专注于脚下当下的这一步，日拱一卒，才能最终登顶。

这一理念让 Steven Bartlett 产生了强烈共鸣，并联系到《原子习惯》（*Atomic Habits*）第一章提到的英国自行车队功勋教练戴夫·布雷斯福德爵士（Sir David Brailsford）。布雷斯福德通过“边际效益”（marginal gains）理论彻底逆转了英国自行车队的命运。他在指导奥运冠军克里斯·霍伊（Chris Hoy）时，严禁运动员去思考领奖台或世界纪录，而是要求他们彻底将注意力沉淀到脚下的踏板上，这一原则被概括为“关注踏板，而非领奖台”（pedals over podiums）：
- **屏蔽终点杂念以提升竞技表现**：当克里斯·霍伊在赛道上满脑子都是世界纪录或金牌时，他的单圈用时反而会变慢；而当他进入完全专注脚下踏板的禅定状态时，成绩不仅大幅提高，赛后甚至记不得刚才骑行的具体过程，完全进入了极度心流。
- **进展感原则（Progress Principle）重塑动力**：布雷斯福德曾向 Steven 透露，当车队开始将宏伟目标拆解成极细小的日常微目标后，员工们不再一到下午 5 点就收拾打卡，反而自发加班到凌晨 1 点，因为每个人都真切感受到了实实在在的进展。
- **《哈佛商业评论》的研究验证**：一项知名调查显示，职场人一天中最开心的时刻，并不是完成重大突破的大日子，而是感受到了“小而确定的进展”。将庞大的 MIT 转化为简单明确的 LIT 列表，正是通过即时进展感持续激活行动力的核心密码。

### [01:17:40](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4660s) 排除干扰以提高信号：降噪耳机与工作背景音的科学
进入专注执行的第三步，Sahar Yousef 强调，提升信号最有效的手段不是往系统里增加更多东西，而是主动做减法，扫除一切阻碍以“调低该死的噪音”。有了清晰的目标与拆解后的执行路径之后，接下来就必须进行严格的注意力环境卫生管理：
1. **执行极简的物理隔离**：手机坚决保持“看不见、摸不着”（out of sight, out of mind），彻底关闭一切不必要的通知推送。
2. **因人而异的声音环境**：如果身处嘈杂空间，或者属于听音乐能提升效率的类型，可以佩戴耳机隔绝外界杂音。
针对 Steven Bartlett 提出的“工作时听音乐与戴耳机在神经科学上有何依据”的疑问，Sahar Yousef 解释道，人群之间存在巨大的个体认知差异。部分人的神经系统容易被背景音乐中的旋律或节奏分散注意力，他们更适合在绝对安静的环境下工作；如果所处环境无法保持安静，主动降噪耳机便能提供很好的物理屏蔽。
然而，Sahar Yousef 发出了明确的科学警告：
> “我不建议每天佩戴降噪耳机或开启降噪功能超过三到四个小时，因为这会改变你大脑对现实世界声音基准线的认知，导致你随后容易被周围真实的现实声音过度刺激。”（Sahar Yousef）
长时间阻断真实世界的环境声波会导致听觉系统的敏感度代偿性上升，重置大脑的主观基准线；一旦脱下耳机，原本正常的日常环境声音就会被大脑判定为过于刺耳的感官过载，从而破坏后续的神经平衡。因此，科学合理地使用声音管理工具，保持环境与感官的张弛有度，才是维持长期高效专注的关键。
### [01:20:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4800s) 降噪耳机与专属音乐：如何利用听觉锚定专注
Sahar Yousef 博士首先提醒人们警惕降噪耳机的过度使用。当一个人长期戴着主动降噪耳机时，大脑的听觉系统会逐渐适应这种极度死寂的环境，甚至误以为“这就是真实世界”。一旦摘下耳机，面对充满杂音的现实世界，大脑就会迅速陷入过度刺激与焦虑。因此，降噪功能应当被严格限定在“专注冲刺”（focus sprint）阶段使用；如果每天计划进行三个小时的高强度专注工作，那么降噪耳机最多只应佩戴这三个小时。
在专注时听音乐也有明确的科学法则。Yousef 建议听完全没有歌词的音乐，或者听自己听不懂的语言，以免语言中枢受到干扰。更高级的做法是为不同心智状态建立“专属歌单”。如果长期在深度专注时只播放特定歌单，大脑神经元就会形成强烈的条件反射与联结。随着时间推移，只要这段音乐一响起，大脑就会自动切换至高度警觉的专注模式。相反，邮件处理冲刺或下班放松、入睡时，则应切换为完全不同的播放列表，利用听觉信号来界定大脑状态。
关于降噪耳机与专注音乐的建议：
- **限制降噪时间**：仅在专注冲刺时佩戴（建议每天累计不超过 3 小时），防止听觉系统过度适应死寂而引发日常感官过载。
- **歌词限制**：选择无歌词音乐或非母语且无法听懂的歌词，彻底杜绝语言信息对工作记忆的侵占。
- **状态锚定**：为深度工作、日常琐事（如清空收件箱）及睡前放松分别定制专属播放列表，训练大脑的自动化情境切换。

### [01:21:44](https://www.youtube.com/watch?v=yePLuwL3FbM&t=4904s) 进度标记与帕金森定律：倒计时的生产力魔力
构建好听觉环境后，下一个立竿见影的动作是“设定计时器”。Yousef 指出，人类以及大多数哺乳动物，生来就极易受到所谓“进度标记”（markers of progress）的驱使。面对 Steven Bartlett 提出的疑问——“是倒计时（60 分钟归零）更有效，还是正计时（0 到 60 分钟）更有效？”——Yousef 明确指出，尽管大脑对任何形式的进度条都极其敏感，但就提升专注与紧迫感而言，倒计时的心理驱动效果最强。
为了形象地说明倒计时的力量，Yousef 举了幼儿园老师常用的“收拾玩具歌”（cleanup song）为例。幼童极易分心，如果只是空泛地命令他们把散落一地的玩具收进盒子里，他们捡起两三样东西后就会转头去玩别的东西。但如果播放一首有明确开头和结尾的收拾歌，孩子们立刻明白时间正在一秒秒流逝；随着歌曲接近尾声，他们会产生极强的目标感并迅速行动。这种现象在成人职场中体现为“帕金森定律”（Parkinson's law）：任务会自动膨胀，填满为其分配的所有可用时间。如果你给自己一小时做演示文稿（deck），你大概率一小时就能做完；如果预留五个小时，它就会拖满五个小时。无论做 PPT 还是打扫房间，设定倒计时都能倒逼大脑提速。
Steven Bartlett 对此深有共鸣。他分享道，五年前读到的一句话彻底改变了他对人生的审视：“你在地球上产生影响力的核心，就是你的时间分配。”无论是在临终前渴望与未婚妻或家人拥有深厚关系，还是追求健康与成就，其本质全部是时间分配的下游产物。现代人往往在无意识中度日，像“风中的塑料袋”一样被低价值的琐事随意裹挟。设定倒计时绝非增加焦虑，而是通过游戏化（gamification）手段唤醒多巴胺，高效浓缩枯燥工作，从而真正夺回属于自己的宝贵生命。

### [01:24:44](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5084s) “真休息” vs “假休息”：2024年《自然》论文带来的警醒
伴随计时冲刺而来的关键问题是：冲刺结束后该如何休息？Steven 提到，像 Steve Jobs 和知名音乐制作人 Rick Rubin 这样的时代先锋，之所以能产出极度违背直觉的颠覆性远见（例如当年乔布斯冒天下之大不韪坚决淘汰 Flash 插件、取消实体键盘与触控笔），正是因为他们拥有一套独特的“无聊实践”（boredom practice）——主动从画面中退后一步，任由思绪放空。这与 Yousef 所倡导的“大脑休息”（brain break）在底层机理上高度契合。
Yousef 严厉批判了现代人典型的休假与摸鱼方式。真正的“大脑休息”被严格定义为：**一段完全不处理任何信息的短暂时间**。然而，绝大多数人从繁重的工作中停下来时，第一反应是打开手机刷社交媒体（如 TikTok）或浏览新闻。2024 年发表在《自然》（Nature）期刊上的一项前沿研究为此提供了确凿证据：研究人员在受试者工作前后测量其疲劳程度，随后将他们分为四组进行休息干预，分别是不休息、刷短视频、观赏大自然，以及目光放空注视前方。
实验结果清晰地揭示了不同休息方式的悬殊差距：
- **最佳恢复：接触自然**。人类进化源于自然，置身于自然环境能带来生理本能上的深层平静与能量修复。
- **次优恢复：发呆与彻底放空**。什么都不做、单纯注视前方，大脑同样能有效消除神经疲劳。
- **最差恢复：刷短视频与无休止输入**。不仅无法缓解疲劳，其恢复效果甚至堪比完全不休息。
Yousef 用举重训练做了一个生动的类比：当一个人举完沉重的杠铃后，正确的休息是彻底放下器械让肌肉放松；如果所谓的休息是“换成较轻的哑铃继续举”，肌肉根本无法恢复。看新闻、刷视频甚至阅读文字，依然在调动大脑负责信息解码、逻辑运算与语义处理的认知肌肉，这根本不是休息，而是持续的低负荷消耗。想要让大脑真正回血，唯一的秘诀就是学会“无为”。

### [01:30:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5400s) 高质量休息与用双手打破分心机制
Steven Bartlett 与 Sahar Yousef 博士探讨了什么才算是一次“真正高质量的休息”。Steven 提到自己正在学习做 DJ，外面甚至摆着四套 DJ 设备，他已经坚持学了四年；在打碟时，因为音乐即将结束、必须精准混音，他的注意力会被完全吸入，这种极致的沉浸感让他暂时抛开了一切烦恼与杂念。Yousef 博士对此高度认可，指出高质量休息的标准正是“让你无法再去琢磨其他担忧与琐事”。
针对日常工作间隙的短暂大脑休息（brain break），Yousef 博士强调绝不能依赖脆弱的意志力，而必须构建硬性系统来防止自己顺手刷手机、看新闻或刷 LinkedIn。她提出的核心策略是“让双手忙碌起来”：
- 抛弃抓起即食的便携零食，迫使自己动手准备食物。例如，不买独立小包装奶酪，而是从保鲜袋里拿出大块奶酪自己切；
- 不喝胶囊咖啡，改为自己烧开水、泡茶或手冲；
- 通过必须“双手协同操作”的物理流程，切断一边单手刷手机、一边进食或饮水的可能性；
- 理想的大脑微休息应当包括补充水分、健康加餐、接受自然光照射、呼吸新鲜空气以及进行简短的散步。

谈及如何激发顶尖的创造力与突破复杂难题时，Yousef 博士从认知神经科学的角度拆解了顿悟（Insight）的产生机制。创新并非凭空出现，其第一步是“充分加载”与问题相关的所有背景数据，让负责思考该问题的特定神经网络高度激活并处于首要位置。然而，真正的瓶颈往往发生在紧随其后的沉思阶段——人们极易陷入思维的“交通大堵塞”（traffic gridlock）。
正如爱因斯坦的名言所说，没有任何问题能由产生它的同一思维层次来解决。Yousef 博士指出，当你苦思冥想时，大脑处于“问题脑状态”（Problem State），这在定义上就绝不是“解决方案脑状态”（Solution State）。想要打破僵局，唯一有效的方法就是主动走开：
- 抽离当前环境，引入全新刺激，例如去遛狗、洗碗或冲澡；
- 当注意力转移，原先过度紧张的神经网络得以松弛，其他处于休眠状态的神经网络与电信号随之被激活；
- 所谓灵光乍现的“顿悟时刻”，本质上是两个原本互不相通的神经网络在后台发生了交叉碰撞。

### [01:33:11](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5591s) 停止反刍与受害者叙事：神经可塑性是一把双刃剑
当 Steven 询问这种离开原状态的逻辑是否适用于负面情绪与反刍思维（rumination）时，Yousef 博士忍不住翻了个白眼，坦言自己对此有极深且不受欢迎的看法。她严肃指出，现代社会陷入了一种误区，即鼓励人们永无止境地反复咀嚼、公开倾诉和过度讨论自己的创伤。从神经学来看，每一次对负面事件的重温，都是在物理层面上加深加粗那条负责痛苦与创伤的神经通路。
Yousef 博士明确澄清，这并不意味着要压抑或否认自己的情绪，而是在充分体会情绪之后，必须果断斩断无休止的反刍循环。反刍思维就是大脑一遍又一遍地陷入完全相同的念头。反复对自己重复“我遭遇了这个创伤、我是个受害者、这就是为什么我变成了今天这样”，这种机械性重复就像培养原子习惯一样，最终会让创伤演变成牢固的自我认同。
大脑的神经网络就像肌肉，你通过注意力、时间和思绪投喂哪一部分，哪一部分就会野蛮生长：
- 识别反刍苗头：一旦觉察到负面死循环再次启动，立即主动转移注意力；
- 重塑叙事焦点：将心智转向你的“珠穆朗玛峰”（人生大目标），选择并喂养你真正想要的人生剧本；
- 成为自己大脑的园艺师与架构师，通过改变认知负荷，让负面神经回路逐渐萎缩（atrophy），让积极回路变得更强健。

### [01:37:39](https://www.youtube.com/watch?v=yePLuwL3FbM&t=5859s) 生产力工具箱中的时钟：时间生物学与“何时做”的科学
在插播关于团队开发的《1% 日记》（旨在通过将珠峰般宏大的目标拆解为每日微小步骤来缓解心理负担）以及呼吁观众点击订阅的互动之后，Steven 将话题转向了 Yousef 博士的生产力工具箱，好奇她为何在工具箱中放置了一座“时钟”。
Yousef 博士解释道，时钟象征着“何时做”（the science of when）的时间生物学力量，它与此前讨论的生产力支柱构成了完整的闭环系统：
- **目标与任务（What）**：由珠穆朗玛峰大目标派生出的 MIT（最重要任务）与 LIT（低强度任务），界定了每天究竟要做什么；
- **执行方法（How）**：专注冲刺法（Focus Sprint），界定了如何以双倍效率且零差错地攻克这些任务；
- **生理节奏（When）**：时钟与时间类型（Chronotype）科学，解答了究竟该在一天中的什么具体时段去匹配上述不同类型的脑力负荷。
人类并不共享完全相同的昼夜节律（circadian rhythm），了解个体的生物钟型态，是实现超凡专注与巅峰表现的关键拼图。
> “The science of chronotypes will tell you the science of when. When should you go about doing all of these different things? Human beings do not share one circadian rhythm.” —— Dr. Sahar Yousef
### [01:40:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6000s) 昼夜节律与三种作息生物钟（Chronotypes）
所有人和动物都拥有昼夜节律，但全人类并不共享同一种模式。虽然人类是追寻光线的生物，但每个人在基因上适合入睡与醒来的时间截然不同。这种基因决定的生理节律被称为作息生物钟（Chronotype），它本质上反映了一个人全天激素分泌与精力水平的波动轨迹。根据科学研究，人类大致分为三种生物钟类型：
```mermaid
flowchart TD
accTitle: 人类三种生物钟类型分布
accDescr: 展示人类群体的三种生物钟类型、占比及其核心生理表现。
A["人类生物钟类型 (Chronotypes)"] --> B["早起型 / AM Shifted<br/>(占比约 25%)"]
A --> C["晚睡型 / PM Shifted<br/>(占比约 16%)"]
A --> D["双峰型 / Biphasic<br/>(占绝大多数，约 59%)"]
B --> B1["清晨皮质醇极早飙升<br/>精力随时间单调递减<br/>无法睡懒觉"]

D --> D1["晨起略有昏沉但迅速升温<br/>下午经历明显低谷<br/>晚间迎来二次发力 (Second Wind)"]
```
第一种是早起型（AM Shifted），即所谓的“早起鸟”。这类人的清晨皮质醇水平会非常早地自然飙升，甚至在清晨 4 点、5 点或 6 点就会自动醒来。Dr. Sahar Yousef 指出，要验证自己是否属于纯粹的早起型，只需做一个实验：把你带到世界上最舒服的酒店，拉上百分之百遮光的窗帘，房间静得掉一根针都能听见，没有孩子吵闹，没有任何会议，让你一直熬夜到凌晨 2 点才睡；然而到了清晨 5 点，脑下垂体和生物钟仍会强行将你唤醒，即便此时严重缺睡，你也根本无法继续入眠。早起型人群约占总人口的 25%，而现代社会的运行架构几乎完全向他们倾斜（如早晨 7 点起床、9 点上学等）。
第二种是晚睡型（PM Shifted），仅占全球人口的约 16%，Steven Bartlett 和 Dr. Sahar Yousef 本人都属于这一少数群体。从演化人类学的角度来看，如果远古部落里的所有人都在晚上 10 点入睡并在清晨 6 点醒来，那么在夜黑风高的致命危险时刻，整个部落面对敌对袭击将毫无还手之力；因此人类需要 staggered（错峰）的值守团队，必须有人在深夜保持警觉。晚睡型人的精力不是在早晨猛冲并随时间单调下降，而是随着时间推移逐渐上升，在下午甚至晚上 9 点以后才达到思维最清晰、最具能量的巅峰状态。Dr. Sahar Yousef 戏称这一类型的人通常“最具艺术感和创造力”，Steven 听到后打趣让她对着镜头再重复一遍。
- 智商与注意力测试的最佳时间因生物钟而异：早起型在早晨 7 点处于巅峰状态；晚睡型在午后甚至深夜才进入最佳状态。
- 晚睡型在现代社会中常常承受“生物钟错位”的代价，因为社会作息并不迎合夜猫子。

### [01:45:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6300s) 认清生理节律与“战略性自动化”的操控陷阱
第三种是人群中占绝对多数的双峰型（Biphasic）。这类人早晨刚醒来时可能带有一点昏睡感（groggy），但在 45 分钟到 1 小时内就会调整到最佳状态。他们在上午迎来第一个精力高峰，下午则经历比其他两类人都更剧烈的能量滑坡（afternoon dip），如果节奏把握得当，晚间还会迎来“第二次发力”（second wind）。Dr. Sahar Yousef 强调，了解自己的生物钟之所以至关重要，是因为它决定了何时进行专注冲刺（Focus Sprint）才能事半功倍：
> “I am a big bag of blood, guts, and chemicals. I'm not a machine.” —— Dr. Sahar Yousef
我们的认知能力在一天当中并不是恒定不变的常量。Steven 分享了自己的亲身体会：他曾经在洛杉矶为了迁就他人而在早晨 7 点参加了一场至关重要的会议，结果状态一团糟；事后反思，他意识到既然会议如此关键，他更应该将其推迟到自己精力充沛的晚些时候。因此他为自己的播客定下了一条严格铁律：绝不在上午 11 点之前开录播客。
当讨论转向当下人们普遍面临的脑雾、分心、内疚感以及外部世界的干扰诱惑时，Dr. Sahar Yousef 谈到了科技大厂背后鲜为人知的阴暗面。她常年生活在旧金山硅谷，经常受邀进入那些正在构建未来的顶尖科技巨头的会议室。科技巨头们极度渴求认知神经学家的专业知识，其核心目的正是利用人类大脑的机制来实现注意力劫持。Dr. Sahar Yousef 的研究领域是大脑的可塑性与认知训练，其中一个核心课题是战略性自动化（Strategic Automaticity）。
战略性自动化指的是让人们在未经深思熟虑（without deliberation）的情况下自动执行某种行为，这也正是 James Clear 在《原子习惯》（*Atomic Habits*）中阐述的习惯形成机制。就像夜间无论多困、甚至倒在沙发上睡着后迷迷糊糊爬起来刷牙一样，这种行为完全绕过了意识审判。然而，当这种无需深思的神经通路机制被大型科技平台恶意逆向工程时，它就变成了将用户牢牢捆绑在屏幕前、不断榨取注意力的无形枷锁。
### [01:50:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6600s) 战略性自动化与科技巨头的“挖角”内幕
Sahar Yousef 博士首先用日常习惯解释了行为自动化的机制。像每天睡前刷牙、早起煮咖啡这样的行为，人类在童年时并不是天生就会去做的，往往是被父母强制要求；但随着时间推移，这些行为变成了一种无需经过深思熟虑（deliberation）的惯性。“战略性自动化”（Strategic Automaticity）的核心目标，正是把思考和纠结从过程中剔除，让行为自然而然地发生。在成瘾机制、习惯养成和认知训练研究中，科学家的目标就是让人无需依靠外部短信或弹窗提醒，便能自动自发地采取行动。

然而，这项原本用于提升人类效能的科学，很早就被硅谷科技巨头盯上。早在 2010 年至 2014 年期间，全球科技公司就开始大规模招揽像 Yousef 博士这样的认知神经科学家。她坦言，自己曾无数次收到此类招募邀请，甚至有些公司因法律限制而无法公开点名。她当场给 Steven Bartlett 展示了一封真实的招募邮件，大意为：“嗨 Sahar，我们在加州大学伯克利分校看到了关于战略性自动化的研究成果，非常希望与您沟通。我们正致力于提升产品的参与度（Engagement）并使其更具黏性（Sticky），不知您是否有空进行一次简短的通话？”
对科技巨头而言，留住用户注意力意味着数十亿美元的商业回报。Yousef 博士明确表示，她并不认为从事这些工作的人天生邪恶，他们只是在面对巨大的工作机会。科技公司给出的承诺往往极具诱惑力：“你可以继续在内部做你热爱的一切研究，我们只是想把成果落地到产品中。”为了证明这种诱惑有多真实，她透露那封邮件所附带的薪资待遇，是她当时从事公共学术研究年薪的整整四倍。面对能彻底改变个人生活轨迹的高薪，科学家们要坚守底线绝非易事。
- 科技公司招募神经科学家的目的：利用“战略性自动化”技术最大化产品黏性与用户使用时长。
- 丰厚的物质诱惑：商业公司开出的薪资高达学术界公共研究薪资的 4 倍。
- 历史根源：科技平台对认知神经学成果的吸纳并非近期现象，早在 2010 年至 2014 年间便已全面展开。
### [01:51:33](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6693s) 科技依赖的代价：“思考阶层”与被算法圈养的公众
面对当下的技术狂潮，Yousef 博士直言：“在当今时代，数字依赖（Digital Dependence）将成为我们这个物种的珠穆朗玛峰（Everest）。”科技与人工智能若被善加利用，能在医学、经济等领域带来划时代的飞跃；然而一旦失控，人类与技术之间的关系将直接决定智人物种能否在地球上继续繁荣。
当 Steven Bartlett 追问她内心最深层的恐惧是什么时，Yousef 博士分享了一段令人不寒而栗的真实经历——这是她在与多位 AI 行业领袖闭门会议中亲耳听到的严峻预判。如果不立即扭转航向，人类社会极有可能分裂为一个极度微小的“思考阶层”（Thinking Class）：
> “我们将创造这样一个未来：社会中将出现一个被称为‘思考阶层’的极少数群体。他们受过良好教育，拥有足够的注意力广度和专注力，能够独立进行批判性思考、提出质疑并创造想法；而这个极其微小的人群——在一个令人毛骨悚然的称谓中被称为思考阶层——将统治世界，至于世界的其余部分，则根本不再被指望去思考。相反，他们的任务只是听话照做；当大众处于涣散和停止思考的状态时，控制他们要容易得多。”——Sahar Yousef 博士
Yousef 博士指出，这种对大众注意力的剥夺正在摧毁近一个世纪以来人类文明最伟大的成就。过去一百年里，教育的普及让思考阶层的范围空前扩大，尤其是女性教育平权，让无数原本无法获得机会的群体能够进行深度思考与创造。然而在算法与 AI 的双重侵蚀下，“思考阶层”正再度急剧萎缩。
Steven Bartlett 对此深有共鸣。他谈到自己目前正极力克制让 AI 代替自己思考的冲动，甚至坚持亲自撰写文字。前一天，他刚对一名下属提出严肃反馈：“在你的汇报文字中，我已经听不到你的思考与声音了。在现实交流中，你的推理逻辑要远比你提交的文稿强大得多，因为你拥有真实的现实世界语境（Context），而 AI 没有。”然而抵制诱惑极其艰难，因为依赖大语言模型（LLM）去代劳思考实在太省力、太诱人了。
- 现代文明的核心危机：数字依赖是人类面临的物种级挑战（“人类的珠穆朗玛峰”）。
- 社会分层隐患：专注力与批判性思维能力正在高度特权化，可能导致世界被极少数“思考阶层”掌控。
- 历史倒退：算法分心正在逆转过去一个世纪全球教育普及与女性平权所带来的心智赋权。
### [01:55:56](https://www.youtube.com/watch?v=yePLuwL3FbM&t=6956s) 生物本能的悖论：大脑为何天生厌恶思考
为什么人类明知会被算法蚕食，却依然无法自拔？Yousef 博士将这一困境归结为严酷的“生物学法则”。人类的大脑生来就是为了寻找捷径（Shortcuts）而设计的。在远古进化史中，食物和热量极度匮乏，如果有一条能省力获取卡路里的捷径，大脑如果拒绝采用就是自寻死路。整套神经生理系统的设计初衷纯粹是为了“生存”，因此追求省力是刻在骨子里的本能。
为了解释这种心理机制，Yousef 博士致敬了同在加州大学伯克利分校任教的已故心理学家丹尼尔·卡尼曼（Daniel Kahneman）——首位且唯一获得诺贝尔经济学奖的心理学家。卡尼曼不仅撰写了划时代的著作《思考，快与慢》（*Thinking, Fast and Slow*），更系统揭示了人类的认知偏差（Cognitive Biases）。Yousef 博士强调，认知偏差并非某种病态缺陷，而是大脑为了在信息过载的世界中降低决策能耗而演化出的启发式捷径。大脑必须在极短时间内判断：对方是否可信？我是否喜欢眼前的环境？我想做什么？如果对所有信息都进行深度计算，神经系统瞬间就会被庞大的数据量彻底压垮。
正因如此，面对 ChatGPT 和各种自动化算法，人类大脑会本能地投降并顺从这种省力捷径。对话最后，Yousef 博士引用了卡尼曼极其精辟生动的一句名言，点破了人类心智最真实的生物学宿命：
> “思考之于人类，犹如游泳之于猫：它们确实会游泳，但它们宁愿不去游。”——丹尼尔·卡尼曼（Sahar Yousef 博士引述）
- 生存法则的局限：大脑天生被编码为寻找能量捷径，以对抗史前卡路里匮乏，但在信息过剩时代这一机制反受其害。
- 认知偏差的本质：它是大脑处理海量现实环境信息时的“节能自保策略”，并非病理缺陷。
- 人类思维的本性：进行深度思考本身就是反生物直觉的痛苦过程，面对算法捷径时具有天然的脆弱性。
### [02:00:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7200s) 深度思考的能量代价与戒除科技成瘾的非羞耻感
对话延续了对人类大脑生物机制的探讨。思考本质上是极其耗费热量的生理活动，与人类节约能量、维持生存的进化本能直接冲突。Steven Bartlett 指出，在食物匮乏的远古时代，高强度的脑力劳动意味着快速消耗卡路里，从进化角度看“消耗的卡路里越多，寿命就越受威胁”，因此人类天然存在避免深入思考的生物惰性。Sahar Yousef 博士对此表示赞同，并以此延伸至现代人对手机刷屏的成瘾机制。
Yousef 博士强调，当人们发现自己沉迷于无休止的信息流或对数字技术产生依赖时，完全没有必要感到羞耻或自责。她直言：“Congratulations, you have literally hundreds of experts that have designed these tools to be as addictive as they are.”（恭喜你，有成百上千名顶尖专家专门把这些工具设计得如此令人上瘾。）科技巨头透彻研究了神经生物学机制，用户的大脑做出上瘾反应只是正常的生理映射。解决问题的第一步并非道德评判，而是像进行血液检查一样获取客观数据，全面评估依赖程度与认知损耗的“出血点”，随后再采取具体的行为干预措施。

### [02:02:18](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7338s) 戳破多任务神话：现场笔迹切换实验与切换成本
Steven 坦言自己长期自诩为一名“自豪的语境切换者（context switcher）”，一直深信多任务处理（multitasking）是提升效率的绝佳手段。为了打破这一幻觉，Yousef 博士现场指导 Steven 在录屏的 iPad 上进行了一项极简但极具说服力的神经科学对照测试，以此衡量其“切换成本（switch cost）”——即大脑注意力在不同任务间来回切换时损耗的时间与能量。

- **对照组测试（单任务专注）**：Steven 在屏幕上画出两条横线。在 Yousef 博士计时下，他全速在第一行写下完整句子“I'm a great multitasker”（我是个多任务高手），随后在第二行一口气写下数字 1 到 20。整套动作一气呵成，最终耗时 **31 秒**。
- **实验组测试（交替多任务）**：规则变更为交替书写。Steven 必须先写顶部的第一个字母“I”，立刻跳到下一行写数字“1”，再回到上方写字母“a”，再跳到下方写数字“2”，以此类推。测试开始仅几秒钟，Steven 便陷入混乱，忍不住爆出粗口并在屏幕前频频卡顿，反复自问“等等，刚才数到几了？”“字母到哪了？”。
- **实验结果**：当计时器走到 **30 秒** 时，Steven 仅仅完成到了数字 **8**，进度连一半都未达到，被迫承认现场彻底变成了“一团糟（shit show）”。

### [02:05:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7500s) 注意力残留与认知关机：碎片化切换的真实代价
通过计算，Steven 惊愕地发现自己在进行数字与字母交替切换时，工作速度足足下降了 **60%**。这意味着如果日常工作中频繁在各类任务与通讯软件间穿梭，理论上工作效率会断崖式暴跌 60%，而且整个过程令人身心俱疲。他回忆测试时的真实感受：每次视线在上下两行之间跳转，大脑都必须耗费额外的停顿时间去重新检索上一个序列的记忆链条。
Yousef 博士指出，这种卡顿在神经认知科学中被称为“注意力残留（attentional residue）”，她更形象地称之为“注意力行李（attentional baggage）”。当大脑尚未完成前一项任务就强行切换时，上一个任务的认知碎片会如影随形地拖累下一个任务。她提出必须建立“认知关机（cognitive closure）”的习惯，如同关掉电脑后台标签页或打包行李箱一样，彻底封存上一项事务，绝不把上一个任务的垃圾带入下一个任务。
- **知识工作者损耗数据**：当前平均每位知识工作者每天仅在不同屏幕、窗口与任务碎片之间来回弹跳所浪费的时间就**超过 2 小时**。
- **生理能量消耗法则**：大脑生物学遵循“天下没有免费的午餐”原则，每一次任务上下文的切换都会对生物系统造成昂贵的能量账单。

### [02:06:04](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7564s) 终极提问：如何通过认知设定成为一个更幸运的人
访谈进入尾声，Steven 拿出了播客的保留传统——由上一位匿名嘉宾留给下一位嘉宾的神秘问题：“听众怎样才能在生活中变得更加幸运？”
Yousef 博士对此给出了基于认知神经科学的回答。她指出，提升幸运的本质是对大脑进行定向“启动预热（priming the mind）”，训练它主动捕捉符合自身期望的幸运契机。因为每个人对于“幸运”的定义截然不同，如果连自己的目标都模糊不清，大脑就根本不知道该去搜寻什么。
要构建强大的“幸运感知系统”，关键在于调高核心信号并过滤杂音：
1. **确立终极目标（珠峰目标）**：站在人生的终局或“临终之床”去反思对自己而言什么是美好的一生，清晰勾勒出愿景与意图。
2. **连接每日重要任务（MITs 与踏板法则）**：明确了领奖台（Podium）的方向后，必须聚焦于脚下的踏板（Pedal），在日常中专注执行最具影响力的核心任务（MITs），持续询问自己今天能做哪一件微小而具体的事来向长期目标靠拢。
3. **定向数据搜集机制**：大脑的运作机制带有宿命般的特征——它会不受控制地在现实环境中疯狂寻找数据和证据来支撑自己既有的信念。Yousef 博士总结道，如果一个人整日沉溺于反刍思维（ruminate）并深陷于受害者心态，大脑就会源源不断地搜集证明生活糟糕的“不幸”证据；反之，一旦将终极目标输入认知系统，大脑就会成为全天候运转的探测器，主动锁定并放大那些通往成功的外部机遇。
### [02:10:00](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7800s) 大脑作为“专注机器”：信念启动与发现机遇的神经学机制
如果一个人始终深陷在挑剔自我不足的心态里，觉得自己“永远做不到”、“离目标珠穆朗玛峰实在太遥远”，那么大脑就会如实配合这种心态。Sahar Yousef 博士指出，当你认定自己是个受害者时，你眼目所及之处便全都是紧闭的门，并坚信那些机会根本不属于自己。大脑的本质就是一台高度敏锐的“专注机器”，它的设计初衷就是不断在环境中扫描线索，并找出证据来证实它内在早已持有的信念。因此，只要提前对大脑进行良性的“启动”（prime），人们就能在日常中发现看似属于“运气”的东西，因为机遇原本就摆在那里。世界并非像人们想象的那样到处充满不可逾越的砖墙，很多所谓的砖墙其实只是带把手的门。
Steven Bartlett 对此调侃道，这听起来非常像流行的“显化法则”（manifestation）。Yousef 博士则从认知神经学角度进一步阐释：无论大众如何定义它——即便视作积极思维也没问题——其背后的神经机制是极其明确的。她以播客邀请嘉宾为例，向 Steven Bartlett 提出假设：如果团队极度渴望邀请到某位看似遥不可及的重量级嘉宾（比如前总统贝拉克·奥巴马，Barack Obama），并且每天清晨醒来都坚定地确立这个目标，那么大脑就会自动将该目标置于最高优先级。正如 Sahar Yousef 博士所断言：“这不仅关乎口头念叨；你的大脑生来就是要寻找证据和数据来支持其信念，所以如果你真正坚信贝拉克能上这个播客，他就会找到通往这张椅子的道路。”（“It's not just about saying it... your brain is designed to look for the evidence and the data to support its beliefs so if you truly believe Barack will be on this podcast, he'll find his way into this chair.”）当目标时刻处于意识顶层（top of mind）时，你在日常生活中便会敏锐察觉到相关联的机会，甚至可能在某个随机场合偶遇对方的前幕僚长并促成合作。

### [02:12:08](https://www.youtube.com/watch?v=yePLuwL3FbM&t=7928s) 像体检一样监测心智：数字化依赖评估与 MMM 研究所
Steven Bartlett 表达了对 Yousef 博士工作的高度赞赏，称赞她不仅拥有将复杂晦涩的神经科学通俗化的大师级能力，更对受众怀有深切的同理心。他特别向观众推荐了 Yousef 博士刚开通的官方 YouTube 频道，呼吁大家主动点击订阅，掌握获取优质科学知识的主动权，而不是被动等待算法的信息投喂。谈及大众如何进一步掌控生活并遵循意图行事，Yousef 博士提出了一项切实可行的建议：第一步应当先获取关于自己的客观数据，全面评估个人的“数字化依赖度”以及当下的“注意力跨度”（attention span）。
绝大多数人一辈子都从未做过正式的注意力测试，根本不知道自己的心智表现究竟处于平均水平之下，还是表现优异到无需担忧。Yousef 博士对此做了一个生动的类比：现代人通常习惯每年去医院做一次常规年度体检，通过抽血和各项指标排查身体潜藏的问题，然而面对心智健康时，大家的反应却截然相反。Sahar Yousef 博士批评了这种普遍的被动思维：“我们不会给思维做体检。我们只是干坐着等它彻底崩溃，然后才想办法补救；就像眼睁睁看着车子着火了才惊呼‘哎呀不好了’。”（“Why is it that we're not checking our minds? We don't do that. We just wait for it to go to shit. And then we do something about it. Like we wait for the car to be on fire and then we're like, oh, oops.”）
为了改变这种“非得等车烧着才灭火”的被动现状，Yousef 博士致力于推动科研工具的普惠化。她秉持“科学应当服务于大众而非追求暴利”的理念，向公众开放了专业评估平台：
- **评估平台网址**：用户可访问其官方非营利科研网站 mmminstitute.org（MMM 分别代表思维 Mind、机器 Machine 与意义 Meaning）。
- **主要测试项目**：提供免费的“数字化依赖指数”（Digital Dependence Index）与注意力跨度测试，帮助测试者看清自身的认知状态并比对全球群体数据，同时匿名协助全球开放科学研究。

Original transcript
[0:00] Every single time you switch your attention, you pay for it. So multitasking is a myth. Yeah. So what we are going to do is get a sense of the amount of time and energy that you essentially waste every single time you switch your attention. Okay, let's do this. All right. Are you ready? Yeah. Get ready. Go. Go. Oh my gosh, this is a shit show. Done. So on a daily basis, theoretically, I'm losing 60% of my productivity just by switching between two different types of tasks at once. And over two hours a day is the average now of how much time is being wasted bouncing between screens and different tasks. If we stay this distracted, we will live a life that we don't like living. So what is in this book? We're going to go through the books. I'm going to teach you all the science for productivity and human performance. Because I know that the default settings of all of our technology are designed by people like me to maximize engagement. of food and candy just going straight in. There's no backstop, but we can use reverse neuroscience to reverse this entire thing. Where's the first place to stop? First, put your phone in gray. Research from my lab shows gray scale makes the phone less neurologically stimulating, and we saw on average people spent one hour less on their phones every single day. That's seven hours a week. Next is choosing long form over short form content. If we have too much short form, your attention span is shot, you literally feel shittier, and your brain operates at a lower level. See in your productivity toolkit, there is a clock. Yeah, this is a huge, huge game changer in terms of productivity. But also there is a focus sprint to help people to do up to two times as much as they would otherwise do. And we can talk about biological chronotypes that dictate the ideal time you should be doing your focus sprints. But also I have another amazing thing to strengthen your mind and make you better at focusing. So I'm going to teach you all this stuff. OK, so let's get into it. So the first thing we ought to really focus in on is... Here is a strange fact. Most of the people watching this right now, about 58% of you, aren't yet subscribed to this channel. Statistically, that is probably you. So could I ask you a small favour? If this channel has ever given you any value at all, please could you do me a favour and hit the subscribe button? It costs nothing, it helps us more than you could know, and the bigger the channel gets, as you've seen, the more we can invest in the guests and the production. So thank you so much and I hope you enjoy this episode. Dr. Saha Youssef, what is the mission that you are on? if you had to try and capture it in a couple of sentences? And why does it matter to the people that are tuning in? listening right now. The mission I am on, is to first and foremost, bring science education to the world, in a way that allows people to work more in line with how their brains and their bodies actually work best. This is my philosophy, that there are fundamental laws of how the brain and the body actually work. And I always liken these things to the laws of physics. There are laws of physics. We don't question the laws. Gravity. I don't ever wake up one morning and go, you know what? I want to do away with it. And I know that there are fundamental laws of biology, but we blissfully ignore gravity. these laws of biology. We don't teach kids when they're in school at an early age how their brains work so that they might be able to study a little bit easier, you know, find flow, actually be able to manage things like stress, physiological stress. We don't teach people the fundamentals of sleep. In my area of expertise is productivity, we focus so much on what? What's the deliverable? What's the long-term goal? What's the annual goal? What's the quarterly goal? What, what, what, what, what, what, what, what, what? But not the how. How should we go about getting these things done? What is the best way, in fact, that a human being might sit down and have an innovative thought? Truly, for example, the neuroscience of innovation. We're all obsessed. I'm from Silicon Valley. We're obsessed with sort of innovation. We're doing that with this. With our brains. With our brains. This is a biological system. Isn't it a good idea to take a step back and learn how the system actually works? I just feel like there's so much friction with how we're working and living today. And I would say the number one thing that seems to be getting in the way of all of this is... At the moment, technology. which is such a shame because it's also... and the most amazing piece of, I would say, modern human invention. You said innovation there. One of the things that innovators often think about is working backwards from the customer, understanding the customer problem and then reverse engineering a solution from there. So I present you with the same challenge with my audience today. Having been out there as a public communicator, you've received a lot of feedback from people as it relates to productivity on what they're really struggling with and how they describe it in their own words. How can they relate to everything you've just said? Like, what are the words that in their head they're using to describe the problem that your work's so
[5:00] Oofs. I hear a lot about brain fog. Okay. That's a big one. I remember working with this female CEO. She said something that's always stuck with me and she's like, I can hear my own thoughts again. that's always stayed with me. I'm like, where were your thoughts before? And that's the heartbreaking truth i think people aren't we're not listening we don't hear the inside of ourselves anymore. I think there's some sort of global discomfort with being with ourselves and we've been distracted. completely 24 7 like every little second and minute in between all of our tasks and to-dos and meetings and calls and this and that is filled in. with technology and scrolling. We're just constantly consuming. And if you put yourself into that sort of setup and state, when is it that you, your mind is supposed to say, "Hey, What about this? I can't cure cancer. That's not my area. I can't do some of the amazing things that people right now are working on, the problems that they're working on to make the world a better place. But in some small part if I can help unblock people to go do. the amazing things that they want to do in the world. If I can just bring the science... of productivity and performance, of focus, energy management, attention, all of these things back into our lives, then this is my small part that I can help people do all of the amazing things that they want to do. and still be happy. What is the experience and the reference points that you draw from? Where did you study? What is it you run now? What studies have you done? I'm the founder and managing director of the Becoming Superhuman Lab, which is a lab focused and obsessed with productivity and human performance. Our goal is to help people get the most done, in the least amount of time with the least amount of stress. I've done my entire academic career at UC Berkeley. My area of expertise is cognitive neuroplasticity, so how the brain actually changes and evolves. Key word there, sort of that root plastic, plasticity. So the brain is constantly changing and evolving and adapting. And I'd like to tap into that. If the brain is constantly changing, evolving, and adapting, that means it could be getting better, which is why my lab has colloquially been called the becoming superhuman lab, because my area of interest is increasing things like your attention span, your memory, your general fluid intelligence. So these cognitive traits that we have and these cognitive skills, I want to increase the volume on all of those things. I want to make people better, faster, stronger. So that's what I've always been obsessed with. me superhuman. I mean, yes. We have to define it though. Of course. Yes. I think you're probably already a fair bit there. No, no, no, no. There's room for improvement. Trust me. Always. For myself as well, always. But I do practice quite a bit of what I preach, but we are human at the end of the day. But I would like to be superhuman. So hopefully we can do that today. You mentioned working with a female CEO there. What is the broad spectrum of people that you've worked with? execs I worked with, and of course, I can't say who, but it's a Fortune, it would be a Fortune 10 company. And I used to do these observations. So I would, let's say if I did this for you, by the way, you'd say, okay, for the next couple of days, I'm going to have this weird doctor lady, this neuroscientist, like follow me around and she's just observing me. Like I would notice like everything from what you're eating and drinking throughout the course of the day, if you take breaks, how you work, I'd follow you to a bunch of your meetings. You know, observing, taking notes, and then we would do an overhaul. And then I would intervene and then be like, all right, we got it. This is going to get changed up. And I have this very distinct memory, because this was a huge point of transition for my work. I'm sitting there in his office and it's a modern, as you might have, glass everywhere, you know, so he's sitting in a glass box. in the middle of a busy floor. This is a fortune tech and he's the boss. So everybody can, you know, he can see everyone, everyone can see him. So you've now put this human being, this extremely intelligent human being that controls billions of dollars, and you've put him in a glass box. Now he also has in mind he's working on a deck for a board meeting. It's extremely important. He's pulling together data that different teams have sent him and he's looking at things he's making pretty big decisions and he's like yeah that's what i'm doing i'm like that's fine you do you I'll be back here. And I see he's on his computer, but he has a second monitor. and the second monitor has his email open, then he has two phones personal and professional and they're both face up right next to him and he had an Apple watch on so as he
[10:00] Sitting down to focus, it's just like, bzzz, bong, bing, boop, bop. And then all of this is happening. And then there's people walking by. And then at some point, his chief of staff comes in and he's just like, excuse me, don't forget this. And he's like, uh-huh. So he's sitting there. I swear, Stephen, he probably got... 30 seconds? You know the average, there was a study done, 47 seconds is the average amount of time. A knowledge worker. stays focused on one screen before another one distracts him. If I told you I want to give you a billion dollars, And I'm here to support you, you know, and advise in any way that I can. But your goal is, in fact, let's say to cure cancer. And it's you. So hopefully you can galvanize the best minds from all around the world. How Would you want them to go about trying to solve this... global issue. of such importance would you strap them up with an apple watch a bunch of notifications a slack and then litter their day with a bunch of meetings and calls and then hope that in the next few years they cure this thing Ideally, you want them to be in an environment with a setup that is Not distracting? and doesn't waste their best thinking. They don't wake up in the morning and it's like, oh, hey, by the way, instead of thinking about that whole cancer bit, you need to jump onto this call and we need to talk about this thing. And it's just constant ping-ponging like this all day. What is this? Just sit down for 20 minutes and just focus. So it's almost it's what's hysterical is. I studied. far more complex things than I find myself talking to people about, which is hysterical. We just need to focus on cleaning this shit up. That's why I call it digital hygiene. There are obstacles in the way. of productivity and performance and focus. Forget becoming superhuman. We just need to become human. Like, do we know, do we all understand collectively here how this human system works? so that we can accept again those laws of biology as you see we come back to this Thank you. Dario Evers here gang, we're going to do something we've never done before. So many of you tell me that you listen to these episodes about wellness, health, productivity, bettering yourself, but there's always this question which is like, what do I do about it now and how do I implement it into my life? So we're going to do a world first. We are going to turn this episode into an online workshop with me and Saha where we're going to film a live interactive workshop that you can attend and we're going to work and actionable tools that you can put into your life straight away. This is the first time we've ever done this but I had this conversation with Dr. Saha that you're about to hear and I just thought you know what there's going to be so much information here but how do we turn this into actions that stick. So if you want to come to this live workshop there is a link on screen and there's a link down below there is only a certain amount of people that can join the workshop because we do have a limit so if you do want to come please sign up ASAP I mean literally within the next 10 seconds and you'll be one of the first to take part in a Diary of a Sear World First which is as we turn everything you learned today into tools that can hopefully change the trajectory of your professional experience and your personal life. Can't wait to see some of you there. I can relate so much to everything you just said, in part because I'm an executive. But actually, it doesn't really matter if you're an executive in this context, because we all live in this very, very noisy world. I want to now go through all of the solutions. You called it getting all the shit out of our way, cleaning up our digital and physical environments. There is a box here. This is... you can you didn't want to make it an app but there is Some of the stuff you talk about is in this box, I guess, as someone that wants to be able to do the best work of my life think clearly interview well build businesses innovate be creative all of those things that you were pointing out through your explanations i want to know like where's the first place to start what's the first domino like if i forgot my sleep is that the first do i have to meditate like what is the there's one that i have to begin with the foundational which you already mentioned yourself as sleep that's true the way that i by the way talk about sleep And I hope this visual stays in your mind and maybe the mind of the listeners here. And I've had the interesting and distinct pleasure of having many a CEO and an executive who is haggard, tired, especially the founders that are grinding, come to me and ask, OK, I want to become one person better. And I find out that they're averaging. Five hours of sleep a night. Like, okay. Can I paint a picture for you of what this feels like? It feels like you've taken your car to the mechanic, and as a mechanic I'm looking at it and the thing is on fire. Like it's literally like it's on fire. The flames are, and then you're sitting there like unaware of the fact that it's on fire, and you're like, "Can we soup up the engine?" I'm like, "Dude, let's put the fire out first. I don't even know where to begin to assess your baseline performance."
[15:00] That's the thing. When you don't get enough sleep, and mind you, that's a minimum of seven hours a night. If you're not getting enough sleep, it's impacting your cognitive performance, your emotional regulation. So it'll be irascible, you know, in the office and with other people. Like the system is messed up. So sleep is, - For sure the foundation. - Okay. - We gotta check that box. I would say next biggest thing that I will tell you right now, this is a global issue. It is impacting everyone from senior citizens to children. It's your relationship. with technology. Thank you. *sigh* What is that? This is a phone lockbox. So we would theoretically put your technology inside and then lock it away from you. Oh, you want to do it? Yeah. Yeah. Go for it. Okay. Let me just make sure it's off. You're like, let me just get rid of some of the things. Yeah. Yeah. Okay. Turn that upside down. There we go. You don't necessarily need to get a lockbox, but the point of something like this is for you as a human being, and your brain as a focus machine, as a monotasking machine, to actually be able to focus. Focus and attention are so fundamental, to all things? personal and professional, mind you. That means any kind of distraction that is diminishing your focus is impacting your memory. Thank you. Another word for memory is... Learning. right attention and memory by the way they're It's impossible to divorce those concepts from one another. They're connected. In the most... connected way that they can be. the way that they're connected is you cannot remember anything that you do not attend to. If you think about that, It is only things that come into your aperture of attention that you're aware of in the first place. So we cannot learn anything, we cannot remember anything, unless we're paying attention. attention spans or ability to sustain attention has been linearly decreasing, Since the advent of this thing, And I don't want people to think it's just phones necessarily. It's notifications in general. And if you're monitoring your inbox all day, and it's constantly available to you, what's your plan for having deep thoughts? The rebuttal that comes to mind, although I don't even believe it, but this is the rebuttal that I think a lot of me and my listeners will be thinking right now. Yes, but what if something happens? I have my email open because maybe a big email comes in or I have my WhatsApp right there because maybe my fiance is going to tell me I need to let her in the house or something's going to happen. Totally. fires. So we call them, right? Fires, urgencies. I get it. I'm a caretaker for both of my, you know, I get it. I call these by the way VIPs. These are VIP notifications and messages. Can I paint a picture for you for a second? Yeah. We figured this out for mail. If you have an extremely important package coming to your house, how do we deal with this in the mail system? Somebody knocks. It needs a signature. Like, we're not leaving this outside. somebody needs to be home knock knock knock i'm going to come and get your attention to me that knock knock knock you need to sign for this is a notification That's the fire, right? And everything else, by the way, just gets shoved in the mailbox. or left by the door. This is what I advocate for. We are all, by the way, "'Smart enough. We should respect ourselves enough.' Truly, I am. to demand better than the default settings. that our apps, our email, our phones come with. The default settings of all of our technology are designed, by the way, by people like me. These are cognitive neuroscientists, behavioral neuroscientists that work at these companies to get you. hooked. Because if you think about this, by the way, what's the bottom line for even a Microsoft Outlook. Forget like TikTok and like all of that. Just leave that aside for a second. Like the boring stuff that runs the world. Email. for those of us adults, right? What do you think the bottom line is when you have a company that has an annual contract with another company that installs things like Slack, things like just Facebook, Communication software. How do you make sure that you re-up that contract? You show engagement. At the end of the year you go, "Look, look at these engagement numbers." Everyone is using, everyone's constantly talking to each other 24/7. So you can't do what you do without us. So that means the way that these softwares and products are designed is for them to be as engaging as humanly possible. So the default setting that your phone comes with, the default setting of every single app that you download on that phone of yours, the default setting of every single app that you download on that phone of yours is the default setting of every single app that you download on that phone of yours.
[20:00] setting of email of any messaging software that all of our teams use the default setting is there to maximize engagement not to make your company more productive these companies don't give a about your productivity that's not their problem that's your problem you need to figure that part out i'm a big advocate for thinking about this in the sense of default settings because it is in fact I have a sweet tooth, so think of a chocolate company. A candy company. What's the, what is their bottom line? What do they want out of me as a customer? And when you say bottom line, for those that don't know, you mean profit incentive, right? Yes. Yeah. Okay. Their goal is to sell as much of their product as humanly possible. Is it their business or responsibility to think about whether or not I get diabetes or if I'm having trouble? With overconsumption, not really. Well, the same is true for email. The same is true for any kind of platform. Its engagement is the currency. So, Everything from the sound that your email client makes when you send an email off, that's been tested. Test it of what will feel the best and sound the best to the human. Everything from the vibrate functionality that you feel in your phone has been highly optimized by people like me to keep you obsessed with the thing and addicted to the thing. to increase your engagement on the platform. And so my big push is in the goal of, again, productivity, the first thing we ought to really focus in on is getting rid of the drains of our productivity first. it sounds obvious but it's totally not obvious that our productivity tools incentive actually isn't your own productivity it is your engagement with the tool because you're totally right when these companies report to investors or whatever they have to show how much engagement i how much you used it and it's almost like antithetical to the mission of the tool for removing your distraction in that regard because engagement and distraction are like opposites in the way that you describe them like slack is distracting me under the premise that it's making me better at my work. Absolutely. Which is why I sort of scoff when I hear, some of these products and tools call themselves productivity software because i'm like well and i'm not suggesting right we don't need to communicate with each other I have team members in different time zones. We obviously need, we've never as a human species, been able to communicate and collaborate at this scale. Technology is amazing. I'm not a Luddite. What I advocate for is People... telling themselves this mantra of i deserve better than the default settings I am better than the default settings. The default settings are not there to help you. So what do you suggest then for someone like me who, you know, I probably spend 10 hours a day on my phone according to my screen time. What should I do? Okay. My my number one suggestion is especially because you yourself brought up the fear around missing important things. Right. Again, I called the fires, the urgency, so on and so forth, is I would recommend setting up what I call VIP notifications in both your phone, your inbox, every single different communication software. And what that means is you come up with your VIP list. This is your partner, your if you have a boss, your boss's boss, if you're client facing or customer facing your top 15 clients. If, for example, these numbers call me or text me, it pushes through the filter. There are no defenses. I need to get that immediately. I have Three keywords, by the way, set up in my email inbox. My first name, I'm a little lucky, I have a more rare first name. So if somebody says Sahar, I'm like, okay, you've got, what is it, you know? Because otherwise, what's our reality, Stephen? Like we're CC'd on email chains with like seven other people sometimes and they're just talking to each other. I do not need to get a ping every single time Stacey and Stephen are chatting with each other about something. They're solving their own problem. Like I need to focus on leading. I don't need to be get like you're all figuring this out. And I'm not saying I do kind of want to be CC'd sometimes. I need to be kept abreast of what's going on, but I don't need to be interrupted. My train of thought doesn't need to be interrupted when I'm finally sitting down to focus. want to be rude. And there's so much social pressure to respond quickly, to say yes, to take the meeting, to do the thing, go to the whatever. So the question I was going to ask you is, who is like the most focused person you've ever met in this regard? And then my sort of sub question was like, I bet they're often seen as rude. Or like, I bet they have to develop a muscle against people pleasing. Indeed, yeah. I honestly probably, the first person that came to my mind is honestly my husband. Who's a faculty, he's here. No, he's in there, isn't he? Besides to me. You'll get a right to reply. Besides to me.
[25:00] He mostly, like his default is no. I have a sense everyone has a default. I'm a default yes person. you know and he's a default no person we run a company together which by the way two people at the helm that's default no default yes i think makes a really good balance because we debate it out everything becomes a discussion i'm like oh this what a great opportunity we should totally do this and he's like this is not the objective stay on the object i'm like well but it's shiny new object and this thing and it's like oh impact and all of the things he protects his resources and his most precious resource is his time his time and his attention. I'll channel him. He'll say, "Yeah, maybe it's disappointing to some that I did not make it to that meeting, but I think people will find over time that my unique contribution to that meeting would have not been relevant. They were just fine without me. And the fact that I did not attend that meeting allowed me to sit down and finish this and do this thing and come up with this idea, which is helping the entire ecosystem of work. I sat and interviewed Kevin O'Leary and he said something to me which has stayed with me ever since, but I know it's also stayed with my listeners because they say it back to me out in the world. He talked about his experience working with Steve Jobs and also... Elon Musk, and he talks about this concept of signal versus noise. Yes. And he said Steve Jobs had the most remarkable ability to focus on the signal versus the noise. He described it as 80/20. And for the for anyone that doesn't understand the analogy, signal is like the most important thing I should be doing today. Noise is everything else. He says the thing about Steve Jobs is it was always like, why are we talking about this? This is the most important thing. And then I saw Johnny Ives being interviewed and Johnny Ives was describing Steve jobs. And Johnny Ives said, the most remarkable thing about Steve is his focus. And he said, focus is, isn't doing one thing instead of another. Focus is waking up in the morning and thinking something is a brilliant idea and with every bone in your body you know that that thing is brilliant and you want to do it and you say no to it anyway. He said, "Steve was the most remarkably focused person I have ever met. and he would often go up to Johnny Ives and ask him what he had said no to and Johnny said he would have these sacrificial things that he wasn't remotely interested in anyway and Steve would know that and push him even harder like what what have you said no to that with every bone in your body you knew was a brilliant idea but you said no to it because we are focused on this and the last part of that story is Kevin O'Leary said that Elon Musk's is the only person he's ever encountered that is more focused than Steve Jobs. Wow. And I, I, I really, this is part of the reason why I'm so excited to speak to you because I want to be more like that. I want to get to 80-20. You're well on your way because you've already given me your thumb. I'm not even kidding. I'm not even kidding though. This is the noise. You can either increase... The signal? or you can decrease the noise. What do you think is easier? decreasing the noise for sure as a first step as a first step of course i think that's actually what they do and again i don't know a ton about this but i actually think that's what they did when they the radio was The job was to reduce the noise. They never mention increasing the signal. Because it's rather difficult. It's possible. It's there. Thank you. It literally get the shit out of your life. We now think that multitasking or context switching is a skill. And we think you mentioned a term earlier on, which I've never had mono. Monotasking. You said the brain is a monotasker. Yeah, it's a monotasking machine. What prove that to me? This thing here. This is a monotasking machine. It is. Yes, it is. So this entire system is designed. for survival human beings are i always kind of joke and say we're not quite competitive in the animal kingdom Like, I mean, I work out, but I can't fight off like an actual predator, you know? My nails are on our teeth. My teeth aren't that sharp. We are kind of puny. But where we're not puny, is this. So it is in my ability to strategize, think, and focus where I can outsmart things. Predators. That's how human beings have survived. That's how we're running the world. Do you know about a third of the human brain, like I, and I say the, the, cortical real estate. So real estate across this human cortex is dedicated just to Looking and Listening. Hmm. That's a lot. just eavesdropping. loud sounds, anything that might come into view. So we're designed to be hypervigilant to anything that might come in our environment, which I mean, think of an open office, think of a typical setup where people are working. Like the example I gave of that executive, literally sitting in a glass box with all the people that he works with walking by constantly and all this noise. And he's trying to find the signal and he's trying to tap.
[30:00] into the signal and I'm like, No. I want our species to keep advancing and I want us to advance as fast as humanly possible. And I know we can, but all the brilliance of humanity is currently being sucked away by these distractions. There seems to be, as I was thinking about that, there seems to be two ways that distractions find us. The first is the notification comes to us, or the thing pings or whatever, the Apple Watch vibrates. The other is we're in the middle of work, and we stumble across something which is a little bit difficult or tricky or a little bit uncomfortable, and we go seeking out the distraction. So, you know, we might be in the middle of an essay. It's a little bit tricky. And so we could reach for WhatsApp and we're chatting in the group chat about the weekend. Yeah. Oh. Is that a... true sort of accurate reflection of how humans behave. Yeah, it is because I was just thinking about my own behavior sometimes. Yes, I don't have notifications on. Well, I don't have most notifications on, but I still find myself reaching for the phone every minute. So the human brain is a problem-solving machine. It's important to keep this in mind. So I'll stack a few, again, biological laws here that brings us to understanding why we all all. have a tendency towards what I would consider to be Avoidance of discomfort. Now, discomfort. Let's list out some uncomfortable feelings. Overwhelm. stress, anxiety, confusion. What are some other ones? You feeling a little depressed, a little FOMO, lonely. What are some other ones? I think you nailed it. Those are all the ones. Anger, frustration. Your brain also, by the way, is your friend. If you don't want to feel them, your brain is you and doesn't want to feel them either. Your brain is designed to help you and When we're overwhelmed, Fuck this. How do I avoid this? So it's going to try to solve the problem. Now there's two ways to solve what you're overwhelmed about, right? You could either deal with it head on, which sounds like a heck of a lot of work, or you could avoid it. No? Emotional avoidance. Now, what's the fastest and easiest way in the modern world we can avoid what's going on inside of us? TikTok, Shake Shack, pornography. So we immediately go numb. And I think normalizing that is the first step. Because what our phones have done for us is created an exit. A very fast, cheap, Exit. to reality. I know you would have heard about those studies where they put people in a room and give them the opportunity to electrocute themselves. So essentially the study is people get electrocuted before the study starts and then they're put in a room on their own with a button that would electrocute them again. They describe... before the study starts on average being willing to pay to not be electrocuted again but once they're put alone with this electrocution button many people continue to shock themselves over and over again and in the study men shock themselves more than women one particular guy in the study electrocuted himself hundreds of times um when left alone and being asked to sit and do nothing and the conclusion from the study is that we'd rather electrocute ourselves than sit alone in silence these days and um Do you know what? It sounds crazy, but in a way that's kind of what we're doing with our phones. In a way, When my phone dies, and I'm just going to be honest, because I don't think there's any point in me trying to fucking pretend I'm something I'm not. When my phone dies, it's like a mild feeling of... anxiety when my phone dies and i'm most certainly addicted to my phone I spend an unbelievable amount of hours with that thing. I probably pick it up 200 times a day just to check. So we're going to remove the phone when we're doing deep work. We're going to turn off notifications. As it relates to the phone, anything else? Yes, there's plenty. I liken... what the tech big big tech essentially what technology has done to really Honestly hijack the brain. and make it addicted? I find... that it is eerily similar to how the food industry got us addicted to sugar and processed food. My humble belief is that it's the exact same three-part framework and it's the playbook was copied nearly identically. We have obviously a fundamental need to eat. Now if you look at the food industry, how might we hijack biology and the brain, yeah, I know, evil fingers. Hell, might we hijack the brain to actually get it addicted, to sugar and to processed food if we know there's a fundamental need there well how you do that is you increase the stimulation of the food and you do that by actually just injecting sugar wherever you can I'm not sure how it is in the UK, but if you in the here in the United States look on the back label of pretty much any loaf of bread
[35:00] that you want to buy and there's sugar in it. I can bake bread. You don't need sugar. necessarily to make a loaf of bread, right? It doesn't have to be a sweet loaf. But lo and behold, there it is. So we're injecting all of this sugar and increasing the stimulation of the food, right? And that's how you can get somebody hooked. Now, why would humans be already sort of naturally addicted to sugar? Because food used to be scarce. It's hard to find. So we're naturally going to be inclined to these things that are indicators of jackpots. Salt, fat, sugar, yummy, yummy, yummy. It's how you make food really delicious. And we're all naturally inclined to desire those things and covet those things and be really, really stimulated by them. So what you do is you inject those yummy, yummy things. So you're increasing the stimulation of your food. Oh, it's so amazing. Then you decrease the friction. Let's make it easier for people to get this stuff. You make everything adorably packaged and portioned out. And you make it easy and easy, fast, like fast food, fast, easily accessible and available all of the time. So you're decreasing the friction. You no longer need to make yourself something. You don't need to make a meal. We have fast food. It's right there, right available. Open up a bar, good to go. Then you decrease the satiation. You decrease the satiation by removing the parts of food that make food satiating. Because remember, this is a fundamental need. I'm hungry. I want to eat something. Satiating being full. Being full. Yes, my body needs things that would make me full. And what makes us full in food? protein? Hmm. Fiber. Candy. Nope, there's no protein and no fiber. So the food industry has figured this out. Technology has done the same thing. They've done the exact same thing. They follow the exact same playbook. They increase the stimulation by increasing this color saturation of the icons and the light that's emitted from the screen. So your actual technology looks more visually stimulating. And that visual stimulation, as we were talking about before, huge part of your cortex is your visual cortex, your occipital lobe. So it's super, super stimulated by all of that color saturation. So it's like, oh my gosh, think of like a casino. You've never been to a casino and you're like, oh, they went with neutrals. You know what I mean? colors all the time all the lights it's all the things So it's stimulating and you keep looking at it. The other way that we've increased the stimulation with technology is short form reels. short form content super super fast tick tock style so that it's uber stimulating and you can't look away And by the way, there's an entire field, intermittent variable rewards. You get these jackpots once in a while. right what's fascinating about the algorithm by the way and your algorithm i'm sure is exactly the same Your algorithm knows you. really really well and it knows what content you're gonna love that day so it's got all this like saved up content for you so it's got like oh Steven's gonna love this. He's really gonna love this because he even liked this thing like a week ago, like something like this. Okay, and it's got this treasure trove of stuff that it's holding for you. You get on to one of these apps and you start scrolling, it's not gonna show you the stuff it knows you're gonna love. Not in the beginning. That's bad business, don't you think? You just came into the store. you have all the energy in the world you obviously have nothing better to do so you've now sat down and in the beginning i can show you meh content i can just show you like hmm in the beginning. because i have your attention and it knows how long it has your attention every person is a little bit different so it knows how long it can just serve you up medium to like low entertaining content and interesting content before you say to yourself I'm done. This is boring. I'm going to get off and I'm going to go do something else. It knows the moment you're about to do that. And right before you do that, hits you with the jackpot. Daryl M.C.O. clip. Like that. Bang. Bang. Exactly. It's like, there he is. It's that Bartlett again. And I can't look away. And I like- People are watching this reel right now. Right now. And they're thinking, this was the one. I was just about to bounce. This is the one. You love this, right? You love this. But there's science behind this. I remember being 16 years old in psychology class and reading about the pigeons and variable rewards. Totally. What is this variable rewards phenomenon? Oh my gosh, it's so- humans are fascinating. I find humans to be the coolest thing in the known universe. We're so ridiculous. Human beings, believe it or not, Do not love. consistent reward. we become more addicted when it's in fact intermittent and somewhat variable. So when we don't know when it's coming, but we know it's coming. Yeah, this is I have a whole theory on like people who are in toxic relationships. Like seriously, think about like love bombing. This is the science of love. I'm like, I'm an asshole. I'm an asshole. I'm like ghosting you. And then bam, oh, I hit you with a bunch of love. And people are like, oh my. And then they become addicted to these toxic fucking relationships. Similar concept. So the algorithm works exactly the same way. If it's
[40:00] showed you every single thing that you wanted to see, by the only diary of a CEO clips, that's it, the whole feed, for like five hours straight. It's just like, bam, bam, bam, bam, bam. Believe it or not, you'd be less likely to get addicted. We're addicted to like the You know, just mess with me. I don't know when the good stuff's coming. I don't know when it's coming. This is how casinos work. This is how slot machines work. You lose. Dude, you know that slot machines are programmed. It's a computer program. it's all math they want you to lose a bunch of money be in the red and then have you make up a dollar fifty and then be like oh i'm back in and it's this is the this is the game this is the human game so The algorithm works exactly the same. That's how they increase the stimulation. So then they also decreased the friction just like food. Here you have... the infinite scroll we literally removed the backstops do you remember the early days of like youtube and instagram you would tell like you only by the way saw the things that you followed that you subscribed to By the way, subscribe. But like this is the point is actually the subscription model allows you to curate your feed a little bit more and say, this is what I want to see, not the rest of this bullshit. Right. When people don't, and so the algorithm will just be like this, this, how about this? How about this other thing? How about this other thing? It's just getting you to shop around. But most importantly, it's we've removed the backstop. Now we have something called the infinite scroll. And the infinite scroll is like going to a buffet and just opening your mouth and there's just an assembly line of food and candy just going straight in. Right? There's no backstop. It just keeps going. It used to be pagination. It used to be like page one, page two, page three. Totally. In the early internet. Now it's just infinite. no end. You're not going to reach the end of TikTok. It's not going to happen. I don't know if you remember this or if people remember this. There was an end. I remember when Instagram first came out, you would literally run out of things to see, and then you'd be like, "That's it. That's all for today. Come back tomorrow for maybe your friend posted another picture of their sandwich." You'd reach the end. There's no longer an end. So that's decreasing the friction. There's no friction anymore. It's just the never-ending scroll. Then they also decrease the satiation. This is extremely important, Steven, going back to that fundamental need. For human connection, We have a fundamental need, like the same need we have for food, to be connected to one another, to be social, to feel a sense of belonging. What a social media has done is it's created the illusion of social connection. Because we have the data to support the longer you spend on these apps and on these platforms, the lonelier you are. So you're lonely. I'm disconnected. I'm at home. I have a sense of loneliness and FOMO, and I'm seeking connection. I want to go meet this need. I have this fundamental need for connection and belonging, and I want to then go meet this need. So what do I do? Well, the fastest, cheapest, and easiest way to do that is Grab my phone. You get on and you think that you're meeting that need. It's like candy. So you have, let's say you're hungry for dinner. Your body is craving things that actually make you full, nutrients that you need. But the thing is, if I gave you a bag of Skittles or something, then you might be thinking, well, Sahara, it's calories. Aren't calories calories? It's food, right? It tastes good, it's calories, and it's going to meet that need. I'm hungry, it's going to meet that need. Well, darling, what's going to happen when you eat candy when you're hungry? I'm sure you've done this before, at least I've done it. And if you say no, then you're the healthiest human and I must study you. Of course I have. Okay. But I want to eat more Skittles later. Okay, there we go. That's the problem. If I have these drunk calories, then in six hours time, I'm back looking for more drunk calories. Exactly. Shoots up. then everything crashes down. Another law of biology, what goes up must come down. So what does this look like when we're scrolling? I seek a sense of belonging. I'm seeking also, by the way, stimulation. We have a fundamental need for novelty and learning, which by the way, I think is it podcasts do this beautifully think about the difference between some 30 second reel that someone has made and then they inject like two quick facts versus sitting down and actually sinking into a multi-hour show. You're attracted to both. One is a lot harder to sit through than the other. But what I'm telling you is this is what's actually going to satiate you. You have, we all do, have a natural fundamental need for learning. and novelty because again, survival. Because this new piece of information might be a huge unlock for me to thrive even more in this world. This is the hijack of social media and short form content. Is you think you're getting that, but I promise you, just like with the Skittles, You end up getting off, and you don't remember anything that you, by the way, you just watched. Test it. Seriously, I'm not kidding. do the quick short form, for a while and in the moment you're like oh my gosh i just learned a fun fact about this and this is you think you're learning it's an illusion what i believe where by the way stephen up for right now,
[45:00] is I think the world is waking up to this now, and this is going to be the new big Reverse Uno, as I call it. they use neuroscience to get us hooked and i think we can use reverse neuroscience to reverse this entire thing if they increase the stimulation as we talked about before, you reduce it. And the ways in which you reduce the stimulation, One, if you keep your phone in gray. So literally going into something like grayscale, makes the phone less neurologically stimulating, so it's a heck of a lot easier for you to actually get off your phone. You do this in settings. And again, this is, by the way, a beautiful example of the default settings are not here to help you. The default settings are here to help them make money off of your attention and your time. So you are better than the default settings, Stephen. I am better than the default settings. Everyone who's listening, you are better than the default settings. Push back against the default settings and put your phone in gray. When you do that, your phone is immediately, it looks dead to you. It's way easier to not go from app to app to app to app. And then do that thing where we mindlessly scroll, especially late at night, when our willpower is low. And then you're like, I'm just going to check for a second, just for a second. And then you find yourself just gorging essentially on this and binging on content. Have they ever tested that? engagement with devices when they are in grayscale or in a different color saturation? Or is it just generally what the neuroscience points to? I've tested it. So in my lab, we took a large sample of healthy working professionals and all i did was turn their phones into gray and ask them to stay in gray for three weeks that's it and we saw on average people spent one hour less on their phones every single day wow that's seven hours a week the way i always talk about that's the difference between you getting that workout in Yeah, that's crazy. Do you know what I mean? It's crazy. When you go around and you talk to these busy people, they're like, oh yeah, I'm trying to do this. I want to read that book. I want to listen to your podcast even, but I just don't have the time. Well, darling, just making this one tiny change will give you an hour back a day. That's seven hours a week. Think about what you could do with that time. Next is choosing long form over short form. Thank you. did you hear that She's from Berkeley. That's an amazing university. She's a doctor. Long. No, it's true, though. She also said subscribe if you didn't. You didn't get that. No, but honestly, it's true. It's really it's not like made up. Short form content has even been shown, by the way, in some cases to increase attention span. I completely agree. Of course you do. Yeah. It's like no one's paying me to say this. But no, long form content, like a film, like a good film has been shown to increase empathy in young people. Just think about that. So like, again, the message is not, oh my God, technology is bad. All screen time is evil. No, no, no, no, no, no. I'm a huge fan of your content diet. Like make sure that whatever, if you want to sit down and watch a movie, sit down and watch a movie, like get into your pajamas, make a, Bowl of popcorn. Like romanticize it. Turn the lights down. You'll put Netflix on? Everyone's also got the phone out. So they're doing two things at once. This has just become like we've accepted this apparently that you no longer have people's undivided attention. So the way in which we're making content now is assuming that someone is looking at something else as well. This is so sad. And please tell me how if this is how bad our attention spans have gotten, how are, first of all, kids supposed to learn in school? You told me that you have this interest in becoming superhuman to experiencing the full potential of your own mind. How are you supposed to do that if you can't even pay attention to a fucking movie anymore? Do you know what's funny? I was watching, um... I was watching a complicated... Old movie. Last night. complicated? It's one of those ones where if you miss a word, the next three hours is you're lost. Oh, yeah. Because they've named a planet Kololubulu. And if you don't understand what Kololubulu is, you're fucked. And I was like, I was, I was having to pay so much attention to this movie. And I remember this from my childhood. I used to just sit there on the sofa with my family and just look at the screen. But it was like I was resisting an urge now in 2026 when watching this very complicated old movie, as if there's now a mismatch between the media that I'm used to versus the way that I and many of us live our lives and It's just it was just super front of mind because I just remember trying to like the effort I was putting in to stay focused on this movie last night and trying to make sure I understood every single word. But I never I never did that when I was younger. You would just sit there and watch. You just sit there and watch. There might be some people at some level. Thinking, yeah, but I love short form. I love it. I love candy too. If we have too much short form, we already know this. You're more depressed. You're more anxious. Your attention span is shot. Like, why would you want that? You literally feel shittier and your brain operates at a lower level.
[50:00] cognitively speaking, if you over consume this stuff, and it's your choice, by the way, I'm not here to tell people how to live their lives. But I want people to wake up to realize one, the fundamental needs are there. So my goal is for you to meet those needs. And the way that you do that to increase the satiation is you actually go learn something new, you actually spend time IRL in real life with real human beings. hold people touch people talk to people have dinner parties have conversations hang out with your friends your family actually meet that fundamental need for social connection. And if you do that, you will notice that you're full and you're you will magically actually like short form less. You are far less likely to lose yourself scrolling until two o'clock in the morning and then feeling like shit the next day because you didn't get enough sleep. I think that feeling like shit the next day is a good way to navigate life, which I heard Jack Dorsey back in a couple of years ago when he was still at Twitter talk about one of them new metrics was reducing regrettable minutes. And this idea of like regrettable minutes, I think, because with Skittles, honestly, they would feel good in a moment, but I'd probably regret if I had a massive bag of skills. couple of hours probably the next day because you know send you on a bit of a roller coaster and with platforms like tick tock When you look at the data, They found that 60% of active TikTok users experience negative welfare and would rather live in a world where it didn't exist, where the platform didn't exist. It ranks as number one in terms of... regret in this regard, because people report that their time was distorted. They opened the app and lost an hour or two hours and they walk away from it without clarity like what they gained. So this idea of regret like okay skittles tastes nice it was it was cool to scroll for a second but how did i feel thereafter is something that i um I guess in the food analogy, is pertinent. Yeah. I'm telling you, we're waking up. People are waking up. Young people are waking up. That's the that's the coolest thing. I saw the graphs from the Financial Times, which showed time spent online had started to plateau since 2022 for young people first. Yeah. Thank God. I mean, but listen, it's still... push. So, The stats are less than half of graduating high school seniors have ever been on a date. compared to what was, I believe, something like 80 or 90%. in, I would say, our generation. That's crazy. That's crazy. I think something like, what is it, a third of UK nightclubs are also now, like engagement in the nightclub scene has gone down to a third. Dinner parties, there's this recent piece in The Atlantic that just came out about this sort of the death of dinner parties. So people are spending increasingly more time alone. and not with others so they're hungry unfortunately these platforms are taking advantage of that perpetual hunger and keeping us locked into the cycle of distraction. And now, by the way, it's socially appropriate for us to always hold our phones. It's always in our pocket. So one of the best things that you can do is actually to aim it, is to introduce portion control. back into how you are consuming content portion control so you increase the friction you do things like that phone parking lot bit like put your phone out of sight out of mind turn the notifications off turning the notifications off would be decreasing the stimulation but increasing the friction is Listen, if I'm telling you this stuff is addictive and you want to do less of it, don't have it right there. It's like sitting down with someone who is freshly trying to become sober as an alcoholic and just be like, "You don't mind if I just put this beer down in front of you, do I? Or do you?" Just as you're working and going about your day. I think the Skittles analogy is pretty good. Like I wouldn't walk around with Skittles in my pocket because if I did, I'd eat them every time I was stressed or bored. Totally. So. This process is what I advocate. I think every young person in the entire world should learn this and know this. I speak mostly to people. older adults have parents, and they're tired of being bad cop at home. They're constantly like, oh, get off your phone, get off this, get off that. So I think this ought to be taught in schools. This has had probably the single biggest impact on my office. Of all the products that I've tried, that have given me productivity gains or cognitive boosts, I would say that exogenous ketones are in the top three most pivotal things that have given me a massive productivity gain. It's some Stanford graduates that have been able to basically bottle up the effect you get from being in a ketogenic diet in a small shot that you can take that makes you feel incredibly focused and gives your brain source of energy and the clinical studies that have been done on exogenous ketones have absolutely blown my mind. I reached out to them, I became a co-owner in the company,
[55:00] And so it's with great pride that I can tell you that this exists. If you haven't tried these shots, go to ketone.com/steven for 30% off your subscription order and you'll also get a free gift with your second shipment. I still buy my ketone shots predominantly online, but thankfully I can now grab them at Target whenever I drive past them here in the United States as well because we're now stocked in Target where your first shot is completely free. I've ever talked to new founders, they all carry the same belief that the biggest threat to their small business is having a bad product. It's not. The biggest threat they face is hiring the wrong person for their small team because bad hires put the handbrake on growth and rapidly infect company culture. And I get it. When you're starting out, you need A players to grow your company, but you don't have 40 spare hours to spend sifting through interviews. So you hire fast to fill the seat. But this ends up costing you even more in the long term. That's where our long-term sponsor LinkedIn and LinkedIn Hiring Pro can help you. It streamlines the entire hiring process from drafting a job description to shortlisting candidates and conducting AI-powered interviews for initial screenings. Nearly 60% of hirers who've used this tool have found a candidate to interview within a week. Hire right the first time around and get started by posting your first job for free at linkedin.com slash doac. That's linkedin.com slash doac and terms and conditions apply. What I really want, quite selfishly, is advice on how to do deep work better um because deep work is something that i mean all of my team have to do deep work they have to edit code could be right we're doing a lot more writing than ever before in part because of ai so we're we're trying to push against that but in a world that is so distracted where my phone is there what advice would you give me for doing deep work predictably well. What we call in our lab and in our work deep work is a focus sprint. Now a focus sprint is a method of working. It's a method of working that according to research, our research, has allowed people to do up to two times as much as they would otherwise do while also reducing the number of mistakes and you feel better because again you're working in line with your brain and your body you don't have that sense of friction where it's like oh my gosh i'm exhausted you know after doing one of these sprints right it feels good to do that kind of deep work so focus sprint is the method first step how many steps are there in a focus sprint Fives. There are five steps. Five steps. So this these five steps will make me 200% more productive. First, set aside time in your calendar in advance to block the time off. You benefit from essentially anticipatory networks in the brain and body. So if you know, for example, that you have a a speech that you need to give a presentation what's the feeling that you get before like some big event or a big speech that you need to give like some butterflies you get this like increase in cortisol and adrenaline right i mean think about how how interesting Amazing, our biology is. I am sitting at rest. Thank you. And even though I am sitting at rest, because I am anticipating that I'm about to get up and maybe do some public speaking, my brain is going to help me by giving me an extra boost in cortisol and adrenaline and all these amazing things, so that I'm a little bit more focused and high energy and I can deal with the thing. It's a bit of a stressor. So, you know, especially if someone has a fear of public speaking, they might be sitting there and they're like, you know? heart rate goes up their hands start to get clammy those are all the markers of physiological arousal as we know them to be so we know that if you can you know a focus sprint is coming you're going to get a little boost. So I'm a huge fan of set it up, know it's coming. Like, I'm going to sit down and I'm going to do a one hour focus sprint. Okay. The other beautiful thing about this from a team perspective is if your team can see your calendar, they can all see that you're sitting down to do a focus sprint because your calendar is public. So it also deals a little bit with that social guilt people feel and that feeling that they need to stay, I need to be responsive to all the things. And now that you've done that, you go to step two, Just you gotta identify what the heck you're gonna do, and you need to define it. You need to break it down in clear, simple terms. So instead of saying, I'm going to sit down and I'm going to work on X, Unless you're going to finish X. That's not going to feel good. This has everything to do with dopamine, by the way. Dopamine is the brain's primary, consider it a motivation molecule. So it's going to get us not only excited and motivated to do a task, but it's also going to reward us a bit if we really do more than we even expected, especially. Which brings me to a few pieces of advice. One, you've got your massive to-do list, yes? You're going to shop from that to-do list. And you're going to say, in this focus sprint, I'm going to take out this one piece. So you have your massive to-do list and you're like, that's the one thing I'm going to focus on. right just this one and then you're going to take that one and then you're going to break it down into small manageable pieces you're going to break it down and you're going to time block every piece you're going to say instead of saying oh i'm going to work on this deck i'm not going to finish it but You're going to say, I'm going to work on slide three.
[60:00] for about, I think it'll take me about seven minutes to finish that slide. Then I actually need to probably send a follow-up email to John for the data that I need for slide 17. Then I'm going to work on this table that I want to put here and then blah, blah, blah. So I want to see in granular detail what the execution list is. And this, by the way, increases your dopamine for getting this work done. If you're not going to finish it, how is that motivating? So the goal becomes an output, not the input. 100 okay that's an interesting one because i think a lot of us do create a goal which is an input like i'm gonna do i'm gonna work on this thing or i'm gonna i'm gonna think about this or i'm gonna strategize this not like the output which is the thing that's gonna be measurable and come out of this work yeah okay that's that's really interesting it's the outcome with a breakdown like i want to see an execution list that feels like a lot of work i'm not kidding to give me a minute and a half. Here's the problem. People start something and I'm sure you've experienced this too. Then the moment they get done with, let's say step one B and they don't immediately know what step one C is or what step two is And it not clearly outlined and it not just Hey execution mode like a machine They go what the next step what should i do next people that when you lose people that when you lose your focus in in deciding what the next step is this is a sprint i don't want you to figure out how to play the game when you're in the middle of the game we need to outline what the heck the game is and then you're going to go into it be like let's go sprint and we go go go go go so you block the time you've communicate it to the people on your team. They know what's happening. You're benefiting from all those amazing hormones and those anticipatory networks. Then step two, step two, you set the goal. And the goal is an output and it's specific and it's broken down into sub goals. Yes. And by the way, you've got in here, diary. So if you've got a daily planner of sorts, something like this, I want you to treat your to-do list, your massive task list. I know you've got one. We all have one. like your refrigerator. Do you have urgent items on your to-do list? Like what is the thing, did you defrost chicken? Because that's a ticking time bomb, that needs to get used. So every single day you wake up in the morning and you're about to choose what are my, I call these by the way in our lab, MITs your most important tasks Your MITs or your most important tasks are the one two maximum three things on any given day that you would want to accomplish if you want your day to be a success So we've got a little chart there, I think, of the MITs, right? Yeah, we do. Every single day, I want you to, in a way, open up the refrigerator, open up the pantry, open up the freezer, and I want you to ask yourself, first, first, how much time do I have available today? Three hours. That's a good day. That's a good day. Like uninterrupted focus time. Not uninterrupted, but I can make it uninterrupted. Beautiful. We'll take it. Three hours is beautiful. Yeah. Now you open up the fridge, the pantry and the freezer and you ask yourself with this three hours, what are my MITs? What are the most important tasks that if I were to do them today would make my day a success? another phrasing for this that we've done research on is what will your future self thank you for it's an interesting question because we often reach for the easiest things and there's the thing that we're not quite ready to do yet because we don't have the information and we're and you know maybe it's a little bit out of our era of competence we don't like finance we don like investing we don like operations so we avoid that and we kind of you know it like opening the fridge as you say and we reach for the thing that we know we love like and we do that those are lit lit like an email a docu sign right um i always say like toilet paper from amazon or something like whatever like the little tiny things that will take five minutes a couple minutes but it makes me feel like i can cross something off and it's like i've done the thing i've done the thing i've done the thing these are the easy things to do that make me feel a sense of progress. We consider these, by the way, these LITs, fast dopamine. And my humble opinion is most of the things that push our businesses forward, the things that push our lives forward are typically here to the right. They're the slow dopamine bits. And I'm not suggesting, by the way, that you don't do LITs. My suggestion is you identify one, two, or a maximum of three MITs that are actually going to push you towards your goals, your long-term goals of things that actually matter. And I assure you the LITs will fill in all of the other nooks and crannies for your day. Like if you've got an uninterrupted hour, that's when you attack one of these MITs. And then if you've got 15 minutes between some meetings and calls, you shove the LITs in there. So MITs are most important goals and
[65:00] I like to use the least important goals. Okay. So going back to the focus sprint, When we said step two is set the goal, what you would ideally do, and this is, by the way, you could do one of two different kinds of sprints. You could do a sprint on one MIT. And what you would do is you take that MIT and then you would actually break it down into small manageable chunks. Okay, okay. In order for me to do that big MIT today in this one hour of time, I'm going to spend 20 minutes on this 15 minutes on this five minutes on this three minutes on this. So you make an execution list, or you could do an LIT sprint, you could do like 15 LITs. Are we assuming that people will know what the MIT is? Like, yeah. I look at this list of 69 things on my to do list. How do I, is there a way for me to know which one is the most important? If you don't know, then I would urge us to take an even further step back and sort of do... a bit of awareness training on what your long-term goals are where do you want to be both personally and professionally let's say in five years what is your everest What is your Everest? If you have a sense of what your Everest is, you then ought to have a sense of what your next step is. If Everest is that way, you're not going to go this way. That way is also quite dangerous. And I will say this. This is... I'm a huge fan of talking about death because I find that it puts everything into perspective. My humble opinion is that the best framing is to really think about yourself on your deathbed. is if you take yourself onto your deathbed and you think to yourself, and truly, by the way, you can visualize this right now, even with me. Let's say you're the tender age of 110 with all of the modern technology and longevity medicine that's going to come out. What looking back on your life? Do you need to have... Experienced. Accomplished? Done? in order for you to leave with a smile on your face. And to just say... It's been real. I did good. I had an amazing life. I did what I wanted to do here and I'm ready to go. See what's next. What's your answer to that? Oh. I want to have loved. deeply. I want to, and this is my own, and I don't know where this comes from. We probably need a therapist on with us to unpack this one, but I'm a firm believer in servant leadership. I think I've been put on the planet to help in whatever ways that I can. So my job is to serve and to make this world a better place with what I do and what I can bring to the table. And that's my obsession. And it's come at a great cost of not doing a lot of other things and not having a lot of what maybe other people see as fun or personal sacrifices. It seems to be the flavor of my mind is that I'm, squarely focused on building better systems for humanity. It was very, it was very clarifying when you asked me to do that as well, because when I closed my eyes and start thinking about my deathbed, I was in a room and what I noticed was first and foremost, who was there? That was like the first thing. And then my second thing was, what do they think of me? So I imagined my... romantic interest being here and then i imagined all of my kids being around the bed and i imagined what they thought of their dying father and there was really like three things that i wanted them to think i wanted them to to think that i achieved things that they can too and to be evidence of that um the second one was around that i'd made the world a better place so they'd like they were clear on the philanthropic impact that their father had had yeah so that was really clarifying because being a good role model to them, and then them having evidence that me being here was net positive to planet. You know, it was really clarifying because there's really three things that matter. So that gives you your direction. Yeah, it does. So if you wake up every single morning, Now with that level of clarity. I can go, the Skittles are not going to bring me closer. Fuck the Skittles. Yeah. Fuck Skittles. Like, what is that? Like, in what way? Like, who on their deathbed is sitting around? and going, damn, I wished I watched more Netflix. Netflix, please don't come after me. Who's sitting around going, damn, I wish I spent more time scrolling and less time with my kids or less time on my mission. on my obsessive mission like nobody um brawny wear as a hospice nurse. and she sat with many many dying individuals what an honor to do such a thing something that I hope to do and
[70:00] my lifetime. as to sort of be, you know, exercise my death doula skills and to be with folks who are passing on. And what an honor it is to sit with them because Oh boy, you get some clarity. So she asked these people, Yeah. What are your regrets? And she would keep a log. of the answers they gave. And the number one regret across all of the people. that she asked this question to who were dying, was, "I wish I lived a life more true to myself." cared less about what others thought. So for you, Steven, it sounds like all that matters to you at the end of the day is the is what your family thought of your accomplishments and how you spent your time. It's how you think. And it's, by the way, it's not even them, because you'll never really know what the other person thinks. We come into this world alone, and we do die alone, no matter how much we love each other. This is one of the paradoxes I find of love and human connection is that from that first cry that a newborn screams out when they're born, they're crying out for connection. They're scared and they're saying, wait, I feel disconnection in this moment. I was connected before and now I feel disconnected. And they're seeking connection. I think humans, we are... seeking this connection and this belonging. for the rest of our lives but the paradox of it the mindfuck of it if i may is we'll never get it. we die alone. Like, I will never understand. your mind. This is the fascinating thing about consciousness. You have your consciousness. I have mine. And even moment to moment, my consciousness now in this moment is different than it was the last moment I've changed. things continue to change and evolve the same moment never repeats itself which means the same self never repeats itself every second that's going by i am in fact sahar v 100 million da da da da da da da. And then the next moment, it's another and the next moment is another like we continue to be dynamic. But that's its own little rabbit hole. But on that own little rabbit hole, there's moments. I completely agree and accept what you're saying. There are these moments When you just feel like your consciousness has... is doing the tango with someone else's it is intertwined and you can we as i say everyone can think of those moments when you look at someone and you go i don't know what it is but at some deep level me and this person are with our consciousness is dancing yeah it's connected And that's a very real thing. I experienced it a lot on this podcast because, you know, I sit here with someone for three hours, talk about their childhood, their trauma, whatever. You feel a deep, deep sense of connection to this other human being. Sometimes it's almost it can be a spiritual experience in a weird but enjoyable way. I think you hit the nail on the head there. I think it's spiritual. I think it's energetic. I think when we feel that experience of what, by the way, feels like flow, I don't know if it feels that way to you, but you feel in flow with the other. Like if you and I can connect in that plane, and I felt it, by the way, even when we were just doing that bit about the deathbed and talking about consciousness. And I felt your eyes just all of a sudden zoomed in. And I even was... I wasn't really focused on you necessarily in that moment. There was something about me expressing... I think what is necessary for two humans to have that flow together, that energetic dance together is a loss of of the sense of self. I think the self must die in those moments, and it does when we completely lose ourselves in this we. I think when we are stuck in our own self and identity, then I am aware of another. I am aware of your perception of me, and you will be aware of my perception of you. But I think those moments where it feels just... magic and we've completely blended, that I'm not no longer thinking about you as an other. And I as I. I and you have become. this energetic we. Mm-hmm. But again, that's a bit more spiritual. No, but it perfectly dovetails into work because we could all think of flow states where we dropped into work and three hours passed. We had no idea that time was passing. We were so in. And it to some degree feels the same as those moments. Like when I'm really into my work, I just time does stop. And I'm so glad it did. I didn't even notice time was a thing. And that's actually the same as being a podcast. When you have really great conversations, you walk out and you go, what, four hours? What the fuck happened? Like, so. Okay. a goal, you have your execution list. You've taken your MIT, you've broken it down, you've made it as easy and simple as like a list of LITs. Another way, by the way, to describe this is an MIT
[75:00] Low dopamine is like a rat going through a maze, and there's a big hunk of cheese at the end of the maze, but that's a lot of work. That is a long, arduous journey to get to that hunk of cheese. Whereas fast dopamine and LITs are like little bits of cheese that you're like, can you just eat that crumb? And it's like, sure, that seems easy enough. Eat right there, right? So the goal is to make your MITs as easy as possible. as a list of LITs. And how you do that is you take that big hunk of cheese and you sprinkle it throughout the maze. So you make your big Everest seem like a series of one steps. to the next step. to the next step lao tzu said it best a journey of a thousand miles begins with a single step uh my husband just um climbed Mount Kilimanjaro. Oh, wow. Yeah. amazing things that I do not choose to do. You said no to that. I said no to that. That's exactly, I don't know how to say no. It's typically with really difficult physical feats. I have my own, but I prefer the mental ones. But yeah, he climbed Mount Kilimanjaro. And when he came back, he said that the mantra of these amazing Sherpas that take you up and down, that come with you, by the way, they're superhuman. Yeah. Like literally running up and down this mountain, even with all of the elevation, as if it's nothing. It's like drinking water then. Amazing. And carrying a bunch of shit with them. It's, Amazing, magic, magic. But he came back and he said what really stuck with him, and it's become a thing that we say to each other sometimes. and all of these amazing guides would keep telling everybody hey Polé polé. Slowly, slowly. Polé polé. Polé polé. Slowly, slowly. It's the only way up to the top. If all you focus on is the Everest, you will not get there if you don't Focus on taking the step every day. a little closer, a little closer, a little closer. You speak to Olympic athletes, they do the exact same thing. That's what I was thinking of. I was thinking of seeing here with Sir David Brailsford, who's the guy quoted in the first chapter of Atomic Habits, turning the British cycling team around marginal gains. Beautiful. He's a good friend of mine on and off camera. And everyone knows about the marginal gains idea focused on the smallest things. He said to me on air, he said, um, he banned his team from thinking about the podium, which is very much what you're saying as emerged that I say to my team, I've said that three times this week, pedals over podiums. And what that means is like really focus on the pedals today because he said that when he had Christopher Hoy, you know, again, he took the British cycling team from being down and out to the greatest of all time. When Christopher Hoy was thinking about the world record or the podium, whatever, his time would get worse. And when he got Christopher Hoy, if he got him to sort of drop into a meditative state and ban him thinking about that, not only would his time get better around the velodrome, but Christopher Hoy would get off the bike and say he couldn't remember the cycle. Yeah. Which I think is this flow state. It is. Other remarkable thing that he said to me off camera was, He went, Stephen, when we started focusing on the small things and broke goals down into really, really small goals, people stopped leaving at 5 p.m. and started staying till 1 a.m. in the morning because we felt like we were going somewhere. And this is what I referred to as from that conversation as the progress principle, which is like the feeling of progress. And there's this incredible Harvard Business Review study where they ask people what their favorite day of work was, and it was when they had a small feeling of progress. So it really resonated with me when you said, turn the, like, MITs into these LITs. Because the reason I like the LITs is because I get the progress principle. Yes. I get the, like, oh, I'm making... I feel like I am going somewhere. Yes. The MIT's It's hard to get that feeling unless you do what you just said, which is breaking them down. Which brings us to step three, beautifully. The best way to increase the signal or to get to X, whatever it may be, is to remove obstacles as opposed to adding. Remove the obstacles, turn down the fucking noise. And you turn down the noise, by cutting distractions. So now you've got your Everest. Pole pole, you know the next step. Pole pole, I love that phrase. Slowly, slowly, the next step. And it's the same thing, it's the pedal, not the podium. Cut out the distractions. Hygiene, hygiene, hygiene. So phone, out of sight, out of mind, notifications off. If you're in a noisy environment or if you benefit from listening to music, then you put on headphones. What is your opinion on listening to music to do work and putting headphones on? What does the science say? People are different. Of course. So some people seem to be distracted by it and they prefer silence. And if you don't, if you cannot be in a silent environment, you may benefit from noise canceling. I don't recommend listening to noise cancelling or having noise cancelling headphones on for more than three or four hours a day because you start to become overstimulated by the real sounds of the world around you because it changes your baseline of what the world ought to sound like.
[80:00] starts to adjust and it starts to think, wow, this is the world. You could hear a pin drop. No, darling, the world is much noisier than that. So then the moment you don't have the noise cancelling on, you become like, oh, my God, and you start getting anxious and you start becoming overstimulated. And also your auditory system starts to actually adapt to the noise cancelling. So noise cancelling, I would say use it for focus sprints only. So if you told me you got three hours a day, that hits your three hours. So you can use the noise cancelling only for when maybe you want to do focus sprints if you benefit from the silence. If you're gonna listen to music, ideally, music with no lyrics at all, or lyrics in a language that you don't understand. You can also benefit from having one particular playlist that you invest in, that your brain will over time, if you invest in it, slowly associate with focus. So you can have like a focus mode playlist, you can have an email sprint, you know, playlist and then you're very, very different from what you might listen to to wind down after work or to sleep. You should have different playlists for different brain states. Okay. So you've set yourself up in that way for success. then, Set a timer. Set a timer. Human beings, and fun fact, most mammals, are highly influenced by what are called markers of progress, which means if we see time ticking by, we will just work faster. Do you mean, is it time ticking down or time ticking up? So is it going from 60 minutes down or is it going from zero to 60? We're keenly interested in any sense of progress or progress bars. Okay. Yeah. Having said that, where I find from a productivity standpoint, you will get a lot of interesting benefits is like just to hustle and to stay focused is seeing the time ticking down. Okay. Using a very childlike example of cleanup songs. Little kids are highly distractible creatures. Now, if you ask them to, they've like strewn about all of their toys, let's say in a classroom, and you ask them to put their toys away, like put all the toys in the bins and da-da-da and clean up, They're going to, by the third thing they pick up, But guess best of luck, right? They're off, they're looking at something else and they're distracted and playing. Here comes the science of cleanup songs. You teach all these kids, and this is true, by the way, across the world when they're little, teachers will teach them to have a cleanup song in class. Now there is a clear beginning and a clear end. to what they're trying to do. And it keeps them focused, it keeps them on task, and they know the song is going to end. And because the time is ticking by and the song is going to end, they all of a sudden start getting very goal-oriented and focused and they start putting the toys away, especially near the end of the song. At Parkinson's Law. Parkinson's law states that work will expand to fit the time that you give it. So if you give yourself an hour to get the damn deck done, It'll probably take an hour. If you give yourself five, I'll take five. Yeah. So time yourself. By the way, time yourself with everything. You need to clean your house. You have some errands to run. Time yourself. You will just work faster. This idea got stuck in my head about five years ago, so I'd like to stick it in some other people's heads. Okay. I read this thing and it said the center point of your influence on this planet is the allocation of your time. And I really tried to interrogate that. I was like, is that really it? Is the game of my life really, first and foremost, how I allocate my time? Of course, then it's like, well, I show up or the things I allocate it to. But the essence here... everything I described on my deathbed, having great relationships with my fiance, having great relationships with my family, achievement, um, the fact the age that i get to the deathbed my health all of it really is you know, downstream from the allocation of my time. What do I put my time on? Going to the gym? Um, Or do I put it on something else? And I just think that's a really important point, because when we talk about saving time and treating time in such a precious way, one of the rebuttals is, oh, this is stressful. This is a... This is... a lot it feels like a lot of pressure to like set a timer but you know Time really is the currency for me. I just think I think it is for all of us. And? I think as well, What I hear from your work is it's not about there being a good and bad way to live one's life. It's just about being intentional with the time. Yeah, I think how unintentional the average day is these days because you're just pulled around like a plastic bag in the wind by fucking. LITs. Anyway, sorry. I think you were very close, dangerously close to quoting Katy Perry there. I really was right here. I think so, isn't it? It's like I'm a plastic bag floating in the wind. That's how I can feel in the modern world. It is true. No, it's true, though. Really? And all of this, by the way, is in pursuit of just... Giving people more of their own time back. By the way,
[85:00] Eh? the way in which we're working with all of these distractions around us, one, according to the progress principle, makes people feel like shit, like, right, they're not happy. They're not happy people want to get good high quality work done people want to make an impact They want those things because you're hiring amazing people and from when we were all little we were told good job You got in it. Like we love that progress. We want to get the gold star So if we've trained an entire generation of human beings to want to get the gold star And now you're surrounded by all these people and you're like hey, by the way I know you have this massive to-do list, but you're not going to get anything done Instead you just have to like answer all these messages and go to all these meetings and calls there and you didn't make progress on anything doesn't feel good. So people don't feel good about it. And then all that work is still left. And then they end up working evenings and weekends to catch up. And that takes time away from your family. And then your deathbed self is like, This is terrible. So the timer will help you condense the damn work. So you gamify it. You make use of the dopamine. You make use of all those amazing hormones that get you all excited to get the work done so that you can actually take a break and do other things oh okay so on this break take a break yeah at the very start you're talking about innovation and creativity and i rick rubin was sat here a couple of weeks ago and i've done a lot of research around steve jobs to figure out how he was able to like see the future because i look back at his decision making and it was always so unexpected and at the time like really contrarian there's a great video of him sort of stood at a developer conference and the developer stands up and basically berates him and says like why are you doing this again you're like removing this particular software that every developer needs this was steve jobs like removed i think it was flash was it flash from our devices so that we could stream video better remove the the stylus from phones the keyboard and he could and he was Rick Rubin and him. seem to share a practice, which is Boredom. So, you know, as productivity people, we're always like, work, work, work, work. But then I study these greats, these visionaries, and I go, oh, they had like a boredom practice where they just like, stood away from the picture. And so when you said brain break, I was thinking, maybe, is this what you're talking about? Or is it something else? This is tactical. Okay. Brain break is just defined as a short period of time. where you're not processing information. And this brings me to really attacking how most humans seem to be taking breaks these days. People will take a break from work and they'll be like, "Oh, I was just like doing all these things and I'm gonna take a break." And what is the most common way to take a break? TikTok. Or something, some other distraction. Some other thing. By the way, there was a 2024 Nature paper that just came out that actually measured everybody's fatigue levels. Okay. before they started working, then they would have them work. So essentially, let's imagine, like do a focus sprint, you're focused in doing all this work. And then they measure their fatigue levels after they're working. And then you're like, okay, now we're going to pause now that you've worked. And you're going to take a break, they put them into four different groups. One of those groups was no break at all. So you just keep going. And then you measured fatigue levels again. And lo and behold, of course, no break. is not great, right? You're not going to really rebound from, being fatigued, but the other options were TikTok-style scrolling, Looking at nature, or just staring ahead of yourself. It turns out the best kind of break is in fact... No surprise they are being exposed to nature. Humans come from nature. I have a sense we might have a affinity for it. Even if it feels like sometimes we don't we're city folk. There is a visceral calm that comes when humans spend time in nature. So that's the best kind of break. But shortly thereafter, it's just doing nothing at all. And the worst break was TikTok-style scrolling. You are just consuming more information. That's not a brain break. Your brain is not in fact taking a break at all. Do you weight lift? Sometimes, yeah. Sometimes, okay. So if you're lifting a weight... Here, I'm going to pick up this block for a second. Let's say this is heavy and I'm picking up this weight, okay? And I'm doing this and my muscles are working very hard. And then what do we do after we've done a set of weight lifting? Rest. You rest. What would you say if in between, instead of actually resting, I start lifting low-grade weights? This is not a rest. So that's what scrolling is. And it's not even just scrolling, by the way. I don't want people thinking, oh, I was reading the news. You're reading. That's not resting this muscle. You're still using this thing. Reading, writing, arithmetic. Like, the point is to rest this thing. How? Do nothing at all. I almost don't know how to do nothing. I'm like, what does that look like? Everything I thought of was a thing. Yeah. It's hard in the beginning. But I will say this. I have an idea for you. Okay. And that is to do something that is cognitively challenging enough
[90:00] - Thanks. such that you can't think of all of your other worries and things. This is my barometer for a good, like a really high quality break. My DJing, what about my DJ? I'm learning to DJ. Are you really? That's why all the decks are out there. There's like four decks out there. I've been learning for four years. So that's my break. Awesome skill. Awesome skill. And you're learning. So it's immersive. I'm totally focused because the song is about to end and I have to mix it. And it's the most locked in I am all day other than this. Yeah. So that's perfect. Great. Even for like a simple brain break, though, my humble recommendation to get yourself to not like scroll, check the news, get on LinkedIn, like whatever else it may be. Do something with your hands. So I'm a big, I'm a firm believer in systems. I'm We just need systems. I don't like willpower, like, oh, I should really do that. I ought to do that. Like, it's really difficult. If you create systems for, and what I mean by that is, don't have grab-and-go snacks anymore. Force yourself to make things - Cooking stuff. - Yeah, exactly. And it doesn't even have to be cooking. Again, you're in the middle of the workday. My point is instead of one of those tiny little cheeses that come prepackaged, get the big hunk and take it out of the Ziploc and cut it and like, "Oh, I've cut myself a piece of cheese." Instead of having the pods, for example, boil some water, put the kettle on, then do the thing. put yourself in a system where you are forced to use both of your hands in order to get yourself hydrated, caffeinated, or get yourself a snack, so that you can't scroll and do the thing at the same time. So that's it. An easy way to take a brain break is just rehydrate, have another snack, ideally, honestly, go expose yourself to some natural light, get some fresh air, move, go on a little walk. But I know those are easier said than done often, So at the very least, I assume people are maybe even at least 50% as hungry as I am. So I love lots of snacks. Is there anything else on this point of, you know, when you're thinking about how to have your great innovative most creative ideas if i wanted to solve a very com complex problem come up with my best ideas is there anything else you'd recommend The science behind innovation and creative insight is the process of Truly understanding and thinking about the problem. So loading up all of the data related to the problem that you're trying to solve. It should be top of mind, meaning, those neural networks that are related to Yeah, the neural networks related to thinking about the problem. Okay, whatever problem it is that you're trying to solve, you want those activated and top of mind. Now, this is one of my favorite quotes attributed, I think, to Albert Einstein, who knows if he actually said it, though. So many quotes are attributed to him. Nobody was who's fact checking the shit, right? But no problem can be solved by the same level of consciousness or the same mindset that created it. So when you're sitting there and you're thinking about a problem, I kind of think about this like it's like a traffic gridlock. like this right you're sitting there and you're going well okay this this and this and it's like and you don't know and by that i mean by gridlock i mean you don't know the solution immediately in fact you're thinking about the problem there lies The brain state of the problem. defined as this defined as x x brain state is the brain state where you steven are thinking about the problem are you gonna is this the solution state No, by definition, this is the problem state. So there you are in a gridlock of certain neural networks where you're thinking about the problem. Ah, the next step. Walk away. walk away and go do something else. Walk the damn dog. Go do something else. Wash the dishes. You're introducing another stimulus here. Right? Shower? New stimulus? New environment? these neural networks begin to loosen New neural networks are becoming activated, new electrical, they're all electrical, neural networks are getting activated. And all of a sudden that might allow one idea to all of it. Ideas are like two neural networks that are crossing paths and you go inside the light bulb that we're all searching for. And then you get that magic and you go, wait a minute, that's There it was, right in front of me the whole time, right under my nose. So you have those amazing insights typically when you loosen and you walk away. Does this apply to negative thinking? Yeah. And rumination. Negative thinking and rumination. I have loads and loads of opinions about Why did you roll your eyes then? I rolled my eyes because... People don't like them. No, it's not that. It's, um... I find that In the modern world, we've gotten ourselves into a bit of a pickle where we've made it okay to continue to rehash and exhaustively talk about and think about our traumas. When you do that, you're just deepening the damn neural networks. Really? Yeah. I mean, think about it. You're like, If I'm sad about it,
[95:00] at something. I'm not saying don't acknowledge your feelings, but after you feel your feelings, But if the goal is, let's say, for example, you've gotten yourself into a rut of rumination about something. or worry. Rumination is sort of the same thought, over and over and over again. The only way out is to break the cycle. You do not make your feelings and, you know, the thoughts that you end up ruminating on go away by talking about them over and over and over again in the exact same way. If you keep doing that, you're just deepening and deepening that neural network so it's even more robust and strong. If you repeatedly, I mean, you mentioned atomic habits. I mean, think about how habits are formed, right? That repetition. So if you keep telling yourself... oh, this trauma happened for me, this occurred, and I was a victim, and then I was a victim, and then I was this trauma, this trauma, and then that's why I am this way that I am, I am this way that I am, I am this way that I... At some point it might become your identity. Pretty quickly, huh? So the only way out is to stop that. You have to redirect your attention. So my solve for things like rumination is acknowledge why it's happening in the first place, and then... Quite quickly after that, redirect your attention when it's happening. It's sort of a anytime you're in that, oh, it's starting again. redirect and then put your attention somewhere else what's your everest what's a different version of the story what's the narrative that you want to feed because again this electrical system is it's think of yourself as the gardener or the architect of this thing you're designing it it's a muscle like anything else it's like someone sitting around and going well i don't love the fact that my right bicep is slightly larger than i didn't do something about it you know you can atrophy this one a little bit and and and increase the weight that you that you that you hold the load on this one and lo and behold you'll get a different outcome. So if you think of the mind and the and really the brain from a neural perspective as different neural networks that you're either deepening strengthening and feeding feeding with your thoughts your time your attention Be careful which ones you feed. Because whichever one you feed will in fact become stronger and louder. Thank you. This is something that I've made for you. I've realized that the Diary of SEO audience are strivers, whether it's in business or health. We all have big goals that we want to accomplish. And one of the things I've learned is that when you aim at the big, big, big goal, it can feel incredibly psychologically uncomfortable because it's kind of like being stood at the foot of Mount Everest and looking upwards. The way to accomplish your goals is by breaking them down into tiny, small steps. And we call this in our team, the 1%. And actually, this philosophy is highly, responsible for much of our success here. So what we've done so that you at home can accomplish any big goal that you have is we've made these 1% diaries and we released these last year and they all sold out. So I asked my team over and over again to bring the diaries back but also to introduce some new colours and to make some minor tweaks to the diary. So now we have a better range for you. So if you have a big goal in mind and you need a framework and a process and some motivation diaries before they all sell out once again and you can get yours at thediary.com and if you want the link the link is in the description below there should be a button just down below here and if it says subscribe you're already subscribed if it says subscriber that means you're not yet and if you're not subscribed please could you do us a favor and hit that button it helps to show more than you know and according to the algorithm you're someone that watches our show but you haven't yet hit that button thank you so much I can see in your productivity toolkit, there is a clock. Why is there a clock? The clock... represents the power and the science of when. Thank you. Let me explain. If we said that the MITs and the LITs that we talked about before, that represents the what. I have my Everest. I have my MITs now. What am I doing today to move incrementally closer to meeting my Everest goal? That's the what. What am I doing today with the three hours of uninterrupted focus time that you said that you had? Right. What focus sprints are the how. How am I going to then go attack that one MIT or that litter of LITs? How am I going to go do it? You're going to do it in the methodology of a focus sprint if you want to 2x your time and minimize the number of mistakes made. That's the how. The science of chronotypes will tell you the science of when. When should you go about doing all of these different things? Human beings do not share one circadian rhythm. What does that mean? Well, have you heard of a circadian rhythm before?
[100:00] Okay, so we all have circadian rhythms. animals do as well. But We don't share one. as a human species. Meaning we don't all go to sleep around the same time. We're not all. We are creatures of light, but we don't all share one rhythm of exactly the ideal time that we would go to sleep and wake up. These different circadian rhythms are in fact called chronotypes. So your chronotype is your genetic biological ideal, time. It's essentially a profile of the hormones and your energy levels throughout the course of the day. And there are three Chronotypes. There is AM shifted individuals. These are essentially, this is like the science behind morning birds. Okay, so people that like doing stuff early. Yeah. Okay. And it's, again, it's genetic and it's hormonal. These individuals naturally, their cortisol levels spike really, really early in the morning. And some people are like the four o'clock in the morning people. They're the five o'clock in the morning people, six o'clock in the morning people. They are naturally AM shifted. Like it's not their fault necessarily. It's, and by the way, how do you know that you're truly AM shifted? How you know you're truly AM shifted is if you go to bed, even if I keep you up at 2:00 in the morning, until 2:00 in the morning, and let's say I'm controlling, you no longer have young children that are going to wake you up, you no longer have any meetings, nothing at all. I've put you in the best hotel in the world with the most comfortable bed, fully blackout, you can hear a pin drop. There's nothing that would otherwise wake you and you can sleep as long as you want. And I kept you up until 2:00 in the morning. Oh, don't you worry. That pituitary gland is very strong. Your body knows when it's five o'clock in the morning. It doesn't even need to see light. It naturally will wake you up. So now you're sleep deprived, but you have no choice. So it's those people that naturally wake up at early hours of the day, regardless of when they went to bed the night before. Those are AM shifted individuals. And it's all about their cortisol levels first thing in the morning. That is about, by the way, 25% of the human population. It's not the majority. My humble opinion is the world seems to be oriented around these people. Right. Early bird gets the worm. Yeah. I mean, everything starts. School started at 9 a.m. So you had to be up at 7. That's why I part of the reason, many reasons, but that's part of the reason I hate school so much. Oh, totally. I like staying up really late. Same. Then you are likely the minority of the human population, like me. PM shifted. PM shifted people, anthropologically by the way, the only reason we imagine why people like you and me exist, Because otherwise, by the way, it's somewhat dysfunctional now. Otherwise, yeah, it would be strange to... have different sleep schedules and stuff like that. Like we're not, I'm like, I'm not a, I can't like see in the dark. Like it's somewhat dysfunctional that we're awake all night. But think about it this way. If you and I were in the same tribe along with my team and your team, and we're all like, okay, we're a village now together. And everybody went to bed at 10 p.m. and woke up at 6 a.m. What would happen in the middle of the night when a competing tribe comes to slaughter all of us? Yeah, the night is like the most dangerous time, isn't it, for anybody? So you need some people that are awake. And then even in the morning, you need some people that are... Mm-hmm. So you do need to stagger in a tribe, stagger the time in which people are highly functional, which makes evolutionary sense. You need a 24-7 team. Mm-hmm. You need to make sure someone's always awake. So... You and I belong to a tiny subset of the human population. According to research from my lab, we're at 16% from what we've gathered around the world. So 16% of the human population is PM shifted, meaning genetically, we tend to be able to stay up quite late and we can sleep in. And our energy levels rise as opposed to shoot up early in the morning and then linearly decreases the day progresses. AM shifted people usually are the best. best focus their best thinking straight away early in the day and they just seem to lose steam as the day progresses like there's no like second wind for them really i mean there's a little bit of a bump but their ideal time like when would you take a standardized test if i wanted to test your intelligence i said come to my lab the becoming superhuman lab like let's test your intelligence your attention span memory all of it when would you schedule that test For AM shifted people, they're like, are you free at seven? Right? Because they're the best in the morning. For PM shifted people like you and I, honestly, the afternoon. Yeah. In my younger years, oh my gosh, the evening, I do my best work like, 9:00 p.m. on. It's my clearest thinking, the most energized, the most clear-headed, you know, up until the wee hours in the morning. But it's not super functional. But it's genetic and you can make use of it. PM shifted people are also have a tendency to be the most artistic and creative. There you go. Can you say that again? Look at the camera and say that again. Most artistic and creative. I didn't. I seem to get those units. Whatever. Um, Then you have the
[105:00] majority of the human population, and those are people who are biphasic. Biphasic stands for the Latin two phases or two peaks, and these individuals wake up a little groggy, but within about 45 minutes to an hour, They're ramped. off to the races they're feeling great by phasic two phases or two peaks so they peak once in the morning they come down for the biggest afternoon dip comparatively to all those three types and then they um will then come back up for a second wind if they play their cards right So those are the three chronotypes. My humble opinion is you should know which one you are because it will dictate the ideal time you should be doing your focus sprints. When? When is the ideal time? I am a big bag of blood, guts, and chemicals. I'm not a machine. Right? There are biological laws. Like, I'm not the same at 8 a.m. versus 2 p.m. versus 8 p.m. I am a different version of self with different abilities and skills. And my attention span is not a constant. That's another... A law that I would love people to know a bit more and accept, I should say. To know and accept. Our cognitive abilities are different throughout the course of the day. which means when we do certain things does matter, at least in some small part. And I'm not suggesting we can architect our days because you and I are actually prime examples of this. As PM shifted people, you know, the world doesn't, give a shit about us. The world doesn't care. Like as in the world is more AM shifted. We have to do a great deal of adjustment. It's not like I can schedule meetings with people like brazenly like, hey, what are you doing at 10 tonight? Right? It's so true. I woke up this morning and did a 7 AM meeting because it was very important and obviously i'm in la so you know i'm working to other people's schedules and i was shit. I don't know how else to say it. It was, I was like, gosh, that's a terrible version of me that I've just protected. Such an important meeting. So I bent my schedule to do it. But actually, because it was important, I should have pushed it as late as I possibly could have, in hindsight. Because I really, I look back on that, my performance of that meeting, that was terrible. You know, even with the podcast, one of the things we set as a rule where I never ever do podcasts before 11 a.m. So this is why this starts at 11 a.m. today. And because I tried it and the brain wasn't on. It's important. I think people are looking for big steps forward in life. But some of these things that seem to be small and marginal can have such a profound compounding impact over the long term. What is the most important thing we haven't talked about that we should have talked about for the people that are at home? And they're struggling with all the... They've got the customer problems we've described. They're brain fogged. They've got these priorities. They're distracted all the time and they feel a sense of guilt around that distraction. They know they could be doing more, but they... The noisy, external, tempting world is constantly winning. What else? Can we give them as a tool? you It's about the way the world is going. I'm at risk of sounding a bit... doom and gloom for a second, but I do hope that there's a light at the end of this tunnel that I hope will give people more agency and will inspire them. Thank you. Because of my job, And because of where I live, I have... Yeah. access to sitting and being invited into meetings and rooms with a lot of amazing human beings that are creating The future. I mean, there is an email there, isn't there, that we didn't touch on, but maybe this is a good time to reference that. You don't like referencing it. It's a bit depressing. But I think it's important because... You live in San Francisco. And you did make the case that... Those big companies are coming to people like you to figure out how to hijack attention. Yeah. My area of expertise is how the brain changes and evolves, how you train it. An area of this that I know quite well because it's extremely important in the pursuit of actual cognitive training is something that we call strategic automaticity. Strategic automaticity is just getting people to do stuff. without meaning to do stuff. So when a habit, right, this is also James Clear's Atomic Habits, phenomenal book, obviously, on habit formation, touches on these kinds of concepts. You want, ideally, You have a behavior or habit happen without thinking, right? Automatic. Think about something that you do without a great deal of thought. or deliberation is a beautiful word for this. No deliberation. For me, it's like brushing my teeth at night. I could be passed out. I could literally fall asleep somewhere on the couch while I'm doing something. And lo and behold, at some point, I will... stir awake and be like, oh no.
[110:00] And then still, before I get to bed, I will brush my teeth. Children don't do this, naturally. They're forced into brushing our teeth at an early age, but it becomes a habit over time, and it becomes a habit that I do without deliberation. I don't deliberate whether I'm going to make my coffee typically in the morning. It's just quite automatic, right? So that habit has achieved strategic automaticity. We have removed the deliberation out of it, and now it happens quite automatically. That's the goal for any habit. Again, I have studied addiction, I study habit formation, and I do cognitive training. Research, which means I'm trying to get people to do stuff. automatically. That's my goal. I don't want to have to send them a text message and ping them every time I want them to do the thing, right? People like me have been hired hand over foot by tech companies around the world. And this is historical. This isn't even a now thing. This was... 2010, 11, 12, 13, 14. I myself have been attempted to be recruited more times than I can count. to bring everything that I know and I've studied and I've done research on into certain tech companies that I've been legally told I'm not allowed to name by name. Just slide me this little thing here. Go ahead. Any mo you received? just you you know, to paraphrase, just says, hi, Sahar, we came across your work on strategic automaticity at UC Berkeley, and we'd love to connect. We're looking to increase engagement and make our product more sticky. Would you be open to a quick call? research collaboration opportunity. lots of people, I guess, in your field get These invitations. Because if they can retain people on their platforms more, it's... billion-dollar outcomes. you you What I will say is that, first of all, I don't think anyone is inherently evil or bad. This is not. It's just opportunities. These are work opportunities, right? And the promise, by the way... for scientists like myself is you can keep doing what you're doing we love what you're doing in fact love it we love what you're doing we just want you to do it in-house so that we can also implement a lot of these things so Mind you, I am allowed to say this. I'm not allowed to name the companies, but I am allowed to say that that particular email came with... an attachment of what the job was, the description, and of course the compensation. The compensation for that particular role was four times my annual salary doing public research at that time. It's tempting. game changing for somebody for their life for their life trajectory right So these were tempting offers. These are tempting offers. Modern day. I would say that digital dependence, is going to be The Everest for our species. And I really mean that. It has the potential, Thank you. If leveraged properly, to give us amazing advances in everything from medicine to economics. It's game-changing. Technology is amazing, especially artificial intelligence. However, comes with a great number of downsides if used improperly. Our relationship with technology is fundamentally critical, For a. In my humble opinion. whether or not our species continues to thrive on this planet. What's your fear? My fear is actually in fact something that I have maybe somewhat disturbingly, um, heard about, This is a real story from real meetings that I have sat in. with leaders in... The AI space. what we are currently up against is what is likely to happen at this point unless we Truly, honestly, unless we turn the wheels and try to do something differently. What we are creating is a future where there will be a thinking class. There will be a very small subset of the human population. That is educated, that has the attention span and the ability to focus. such that they can think critically on their own. They can question things, they can come up with ideas, and this small subset of the human population In a creepy way, again, I've heard it called the thinking class. They will run the world. and the rest of the world will not be expected to think. Instead, Their job will be to just do as they're told. and it is far easier
[115:00] to control a populace when they are distracted and not thinking. They're not awake. And this is my fear. And this is in fact what has, what is motivating me on a daily basis. This is my Everest at this point, is to illuminate what is a healthy relationship, an intentional relationship between minds and machines such that we don't lose our meaning. And this is what I'm obsessed with on a daily basis at the moment, is giving agency back to people and trying to wake them up and get them to realize that if we stay this distracted, we will live a life unintentionally that we don't like living, you will end up on your deathbed with more regrets than you can count. And at a social and global level we are going to have a drastic change from this last century This last century by the way has been absolutely amazing as it relates to education for people We have been educating more human beings Think of girls and how much progress we've made in the pursuit of equity and equality for women. How many women are now extremely highly educated and doing amazing things where we would not have had that luxury a few generations ago, one generation ago, in fact. We've made such amazing strides, in fact, to expand the thinking class. The thinking class used to be small. And I'm telling you now that it is shrinking again. Because of algorithms and AI. AI is taking a lot of the thinking away from us. And I'm using my words quite carefully there. It's taking it away from us because we're also we're letting it earlier when i said we're writing more than ever and the reason i said that was because i'm actively trying to resist the temptation of allowing ai to think for me and i had a conversation actually yesterday with one of my colleagues who reports to me and the feedback was um i no longer can hear your thinking i can't hear your voice but actually i said to this person in real life your reasoning is so much stronger than when you send me things that are written And that is because that not you You actually better than me AI because you have more context. You have more real world context. And I think it's a really interesting moment for people to resist the temptation to let ChatGPT or an LLM think for them. But gosh, it's going to be so bloody tempting. It's tempting. Oh, Stephen. What's wrong? It goes back. What's wrong? What's wrong and what's right at the same time, it's another paradox, it's another paradox, is those damn biological laws. The human brain is wired for shortcuts. Meaning, if there is a shortcut to food and calories, we're gonna take it. We're supposed to because food used to be scarce. We be idiotic not to Remember survival This whole system is there for survival We are designed to take shortcuts Now I will give some props to Daniel Kahneman Danny Kahneman go Bears UC Berkeley professor May he rest in peace Also the first psychologist first and only if I not mistaken psychologist to win the Nobel Prize in economics Now Dan Kahneman is quite famous for not only writing the world book Thinking Fast and Slow but as a researcher my humble opinion, more famous in my world of illuminating cognitive biases. And these are not necessary. I don't want people to think like, oh no, they're bad. It's not like a disease model here. these are the shortcuts we're talking about. The human brain is trying to figure out very, very quickly, can I trust you? Do I like you? Do I like what's happening? What do I want to do? What am I attracted to? What am I motivated to actually go get? It's just trying to decrease the amount of energy that it takes to make all of the decisions. Otherwise, the world is far too stimulating and full of way too much data and information. It would overwhelm us. So the brain is designed to make all of these parses all this information and it's designed for shortcuts daniel kahneman is famous i one of my favorite quotes of his thinking is to humans as swimming is to cats they can do it but they would prefer not to okay cats can swim they don't like it
[120:00] Yeah. So thinking is the same way. It's against our survival instincts of energy conservation, relaxing, preserving, you know, especially in a world you talked about earlier about where the calories weren't abundant. Like even doing this conversation now requires a lot of thinking. It's burning a lot of calories. And we need Skittles. Exactly. The more calories I burn, my days are numbered, right? Like from an evolutionary perspective. So that's an interesting thing that we don't actually want to think. Hmm. It's important not to have shame around it. This is also connected, by the way, to the scrolling and our relationship with our technology. There's no shame if you find yourself dependent on scrolling addicted somewhat and you're not happy with your relationship with technology. It's okay. Please don't feel shame or guilt around it. It's natural. Congratulations, you have literally hundreds of experts that have designed these tools to be as addictive as they are. Lo and behold, you have a brain that we understand and your brain became addicted. So there's no shame in it. It's just what do we do next? And my humble opinion is first assess, get like a blood test, essentially, like get data on patients. How bad the situation is, where are the bleeds, and where is it worse? and where is it okay, and then go implement some of the tactics that we talked about. One of the things I'm terrible at is, I think I mentioned this earlier, is I... I think multitasking is, I've always believed it is a thing. It is a more productive solution. And I consider myself to be a very proud context switcher. But then I heard about this... exercise that you do to prove to people that multitasking is a myth. I have my iPad here and it's recording the screen. Okay. So I can show the audience my iPad. What is this thought experiment or task that highlights The myth. It's so simple too, by the way. So what you're going to do for me, Stephen, and draw two lines on that piece of paper. And what is this going to prove? from a high level. What we are going to attempt to do is do using the most... I would say ridiculously oversimplified quote unquote task. This is insanely easy for you. But what we're attempting to do is get a sense of what we call your switch cost. Your switch cost is the amount of time and energy that you essentially waste every single time you switch your attention from A to B, B to C, so on and so forth. Biological law, another one. There's no free lunch. Every single time you do something with your biological being, you pay for it. We shall see. Okay, let's do this. We shall see. Okay. Whenever you're ready, you're going to go ahead and draw two lines for me. And I'm going to time you, so don't start yet. But what you're going to write on the top line is you're going to write, I'm a great multitasker. And on the bottom line, because you are, right? Wink, wink, nudge, nudge. I'm a great multitasker. Okay. And then at the bottom line, you're going to write the numbers 1 through 20. And you will do this as fast as you possibly can. And I will time you. Okay? And I will read out the times out loud. All right. Okay. Are you ready? Yeah. Get ready? Yeah. Get set. Go. Okay. . Thank you. Thank you. Thank you. From 0 to 20? Thank you. Thank you. *click* Thank you. Thank you. expletives are natural okay okay done yeah 31 seconds okay beautiful i want you to do this one more time okay This time, the way in which you will arrive will be a little different. You're going to alternate. So you're going to start at the top line and you're going to write the letter I. You're going to drop down to the bottom. Don't start yet. I'm going to time you. Yeah, down to the bottom line, number one, back up to the top line. Letter A down to the bottom line, number two back up to the top line, letter M down to the bottom line, number three, so on and so forth until you finish both lines. Okay. I'm going to give you one other option because if you're thinking, Sahar. This hand is a NASCAR. Like I'm going to lose time going back and forth between these two lines. Fine. You can do it all on one line, but you still have to alternate. So it still needs to be I, one, you know, two A, so on and so forth. So it needs to like alternate all in one line. So it's going to look like a garbled mess. So it's a little harder to track in my opinion, but some people prefer it. Do you know what? If I get to 31 seconds, just tell me and I'll stop. Okay. Because it's that you're already anticipating it's going to be that painful. Yeah. Okay. All right. Get ready. Yeah. Get set. Go. Bye. Okay. Thank you. Fuck, I forgot to count. That's weird. Oh my gosh, this is a shit show. But where was I? There. I think I cheated. I just feel like I've cheated. Bye. I'm sorry. We're at 30. How far did you get? I got to number eight. Okay. So that was...
[125:00] My maths isn't great, but that is 40% of the speed and when I just focused differently, 60% slower when I was multitasking between numbers and letters. So on a daily basis, theoretically, I'm losing... potentially 60% of my productivity, theoretically, just by switching between two different types of tasks at once. Yeah. So you're not only getting less done, energetically. One is more expensive than the other. Do you know what? it was way less enjoyable. It was painful. Do you know the other thing? Yeah. It really did remind me of the... how I've been working because every time I went from one line to the other, I went from the letters to the number. I had to like remind myself again of where I was with the numbers. Yes. That makes sense. And then when I went back to the letters, I was like, where are we again with the letters? Totally. So there was a little bit of a gap there in me trying to figure out what came after the letter I, for example. It's really fascinating because it's so illuminating. By the way, there's a name for that concept that you were just, you were feeling it. It's palpable. Yeah. It's called attentional residue. Yeah. And it sounds gross, right? Yeah, attention, yeah. I call it attentional baggage because I find the visual that that creates better. meaning you carry, into the next task, all the shit, the baggage from the previous task, unless you close out. I say get cognitive closure. close out the tab, so to speak, on your computer and just be like, all right, this, I'm going to do, clean up shop, get cognitive closure, close the box and don't carry one bag into, you know, box or a bag, don't carry it from one thing into the next thing. Try to, as much as possible, get cognitive closure. When you multitask, one, you're barely onboarding to the next task, you're carrying shit from the last one. It's taking you longer to actually finish anything. By the way, over two hours a day is the estimated... Average now, for the average knowledge worker just bouncing. between screens and different tasks. I think it's absolutely wild. So we have a closing tradition on this podcast where the last guest leaves a question for the next guest, not knowing who they're leaving it for. The question left for you. Very good question left for you. Very good question. I love when this happens is. How can the audience become more lucky? Oh! I love this question. And... And I have an answer. Which is nice. Yes. It's nice when that happens. Luck. The way to become more lucky, is to prime the mind, to train it, I would say, to look for luck. Your luck. Because lucky for you, I'm assuming, would be is very different. than my luck and the next person's luck. You have to know what your Everest is again. You need to go to that deathbed. Figure out what a good life for you is. Figure out what your intentions are. and your goals like what is it that you're looking for because if you don't know then there's nothing for you to look for. We don't even know what you want to get lucky at. Right? So one, you have to get crystal clear on what it is that you want. right once you're crystal clear on what you want you need to ask yourself and remind yourself on a daily basis what that everest is and then you need to it's it's that you said it beautifully Is it pedal versus podium? Yeah. Right? What is the one thing I can do today that is going to make... me incrementally closer to that long-term goal if you prime the mind with what is your goal what is your everest what is uh what what are your objectives are what you're looking for what you're hoping to get lucky about. what you're hoping to get lucky in, then if it's on your mind, instead of all the bullshit that we fill the mind with, This is turning the signal up. We talked, all of this conversation has been about turning the noise down. And parts, we talk about the signal. When we talk about your ultimate why, your Everest, your long-term goals, that deathbed self, And then we talk about the MITs, which is the pedal. How can I drive my day? What can I do today that's going to make me incrementally closer to that long-term goal? Right? That's the what, so to speak. Thank you. In order to get more lucky, The mind *sigh* bit spooky, it will look for data and evidence to support its beliefs. Either way, Either way. So if you ruminate, if you stay in that victim mind,
[130:00] set. If you stay in that, oh, look at my shortcomings, I'm never going to make it. I'm so far away from that. Everest is all the way up there. Guess what? you will notice what you will notice are closed doors, Because apparently you're a victim. and they're not for you. You will notice all of your shortcomings and you'll focus on them. This is a focus machine, as we said. This thing is designed to look for the evidence and find the evidence that confirms its beliefs. It's constantly scanning. So if you prime this thing, Oh. You'll find your luck. Because your luck is right there. The opportunities are there. The world is not full of brick walls the way that it may seem, Those brick walls are doors. They have handles. I feel like that's manifestation. I want to push you further. And if people are into that, I think, great, positive thinking, it's all lovely and beautiful. I mean, what are you trying to achieve here? What are you trying to achieve is like, do you have a guest that you're trying to bring on that you that you've not been able to find? And you're just like, I want you to be wake up every single day and just like be like, I will find my way to you. You will find. Let's get Prangu Pama on this podcast. Let's do it. No, no, if you keep saying it will happen. But it's not just about saying it. you will be thinking about like that is one of my goals you i promise you you're gonna see opportunities you're gonna end up meeting one of his former chiefs of staff at a random it's just gonna happen because it's top of mind for you and your brain is designed to look for the evidence and the data to support its beliefs so if you truly believe barack will be on this podcast He'll find his way into this chair. Okay. I mean, I just love your work for so many reasons. I think sometimes the complicated can stay complicated until it finds the someone like you who has the ability to simplify and have the empathy to understand those that they're simplifying it for. And I was super excited to see you just started a YouTube channel. I did. And I would highly recommend people go and subscribe to your YouTube channel. I'll link it below, but it should be, if we collab, you should be able to see the little icon there. Highly recommend you go and subscribe to Dr. Saha because, you know, she's continuing to do great work. She's continuing to learn and share that knowledge with all of us. And it saves us follow her and have the, you know, you don't want the algorithm to be serving up your content, you want the subscription button. So go ahead and follow Dr. Saha over on her channel as well. Is there anywhere else people should go to get your work or to understand more about you to follow you? Yeah. I want to help people. One, gain control over their lives and live a life of intention, of their choosing, whatever it is that they want to do. So my humble recommendation is to... gain some data on you. to actually assess your digital dependence, assess your attention span. Have you ever taken a test of your attention? No. Like, do you know where it falls? Like, maybe it's not so bad. Maybe you're off the charts amazing. We don't need to worry about it, right? I'm a firm believer the way that, and I would love the world to change in this way. And I know, and I hope in some small part, we can help make this more of a common thing that people do. But the same way that we go to the doctor once a year, and we have this like annual physical, usually, you know, like, how am I doing? I get a blood test, you check all the things. Why is it that we're not checking our minds? Amen. We don't do that. We just wait for it to go to shit. And then we do something about it. Like we wait for the car to be on fire and then we're like, oh, oops. No, we should have things that we're doing along the way. But how do we know what to do? the data. If we collect data and we actually have assessments available to people, so I'm a extremely passionate about making scientific assessments available to the general public. I think science should be for people, not profits. Where do I find the assessment? You go to mmminstitute.org. MMM. Mind, machine and meaning. Institute.org. OK, I'll link that below and I'll put it really big on the screen here. www.mminstitute.org free assessments. Thank you so much for being here. Such a lot. And please keep doing the work that you're doing. You're a star. And sometimes once in a while I meet stars and you're suddenly a star. So I'm excited to watch your career unfold from here on outwards. Thank you, Dr. Sarah. We're done. Thank you. Okay, so if you've enjoyed this episode, we're going to do a world first, as I said at the start of this episode. We're going to turn this whole conversation into a live interactive workshop that's taking place soon with me.
[135:00] and Dr Saha. If you want to sign up and be part of that, there's a link on screen now and there's a link below. here's what you'll get from it when we have these two three-hour conversations there's so much information but oftentimes you message me and say Stephen like I learned all this stuff but I don't know what to do next it's kind of like we walk you to the shop and then we leave you in the shop door so with this workshop that me and Dr Sahar are going to put on we're going to take everything you learned today and break it into actionable principles that you can take into your own life with physical workbooks and other materials so that it sticks and also you'll become part of the community who are all working on this challenge and opportunity together. I hope to see you there. There is only a certain amount of people that can join the workshop because we do have a limit. If it sounds at all interesting, trust me, this is the one you want to join. It's going to be amazing. The link is below and I hope to see you guys there. Thank you. YouTube have this new crazy algorithm where they know exactly what video you would like to watch next based on AI and all of your viewing behavior. And the algorithm says that this video is the perfect video for you. It's different for everybody looking right now. Check this video out. I bet you, you might love it.
