Blurb/Description: A deep dive into the modern attention crisis, exploring the forces that are destroying our ability to focus – and worse, that of our kids – and what it takes to reclaim our minds.
Summary: Johann Hari’s Stolen Focus investigates the collapse of collective and individual attention. If anyone asked me for the single most important book to read in 2025, this would be it. It’s important for us in both our work life and our personal life – not just for human flourishing as an individual, but equally important in our relationships – and especially important if you have kids.
Hari argues this isn’t a personal failing but a systemic problem driven by multiple forces, including (but not limited to) smartphones and social media. It powerfully explains the tech industry’s incentive structure – our distraction is their profitability. He explains how an environment of constant interruptions (context-switching) and “multitasking” degrades our ability to think deeply. But technology is only one part of the crisis. Hari also examines how chronic stress and trauma create “hypervigilance,” a state of constantly “scanning for unexpected dangers” that makes sustained focus impossible; he also delves into ADHD and childhood structure vs. play. The research and synthesis of ideas is truly profound.
While some links are stronger than others, I find there are few wasted words in the book and each section is profoundly thought-provoking.
Highlights: The book excels at exploring the attention crisis – perhaps one of the most important of our time – links to psychological research ranging from flow states and mind-wandering / the default-network; it fits in very well with many of the other books on the site.
Lowlights: I have a running joke with my wife: whenever I pick up a new Johann Hari book, I say, “I can’t wait to see how socialism is the magic solution for [Problem X.]” Hari is a progressive / socialist / whatever and while he does incredible research and is very thoughtful (and an amazing writer), he does have one bad habit… all of his books tend to have tedious sections (sometimes an ending chapter or two) that, more or less, conclude that holding hands and singing kumbaya are the solution to all our problems.
He goes so far (in some cases) as to recommend wild things like the government controlling social media, which has its own problems (for example, censorship, as evidenced during COVID) – he seems to understand n-order impacts generally, but is apparently completely oblivious that government control of communications could cause vastly worse problems than we have today. (He provides a token example of the BBC, but I hardly find this compelling.)
More broadly, Hari discounts the value of human agency (explicitly downplaying or arguing against self-help solutions, for reasons I find unfathomable). As with all socialists, Hari profoundly misunderstands human nature and basic in-group / out-group behavior, incentives, etc.
While I love reading Johann Hari’s books and find his deeply researched and contrarian viewpoints very thought-provoking, I disagree vehemently with him philosophically; there’s certainly nothing wrong with structural problem solving – or even many regulations – but the more immediately useful solution is often the personal one. The good news is that these sections are usually towards the end of his books, meaning readers can start skimming (or entirely skipping) once he wanders off from thoughtful, well-researched science into progressive fantasy-land.
All of that said, I rate these issues as merely a minor annoyance in the context of what is overall a phenomenal, and thought provoking, and critically important book (which is why it gets the rare full 7 stars).
Mental Model / ART Thinking Points:
- The book powerfully debunks the myth of multitasking (Page 37). What we experience is “task-switching,” which comes with a “switch-cost effect” (Page 38) because the brain has a fundamental bottleneck – it “can only produce one or two thoughts in your conscious mind at once” (Page 37).
- The core of the crisis isn’t personal failure; it’s the incentives of the business model (Page 118, 125). Surveillance capitalism is in a zero-sum “arms race” for attention (Page 114), using negative choice architecture like infinite scroll (Page 120) and exploiting our “negativity bias” (Page 131) because “Your distraction is their fuel” (Page 114).
- The book highlights two kinds of attention: “spotlight” focus and “mind-wandering.” We’re losing both. Mind-wandering (the default mode network) isn’t a flaw; it’s “a different form of attention” (Page 97) essential for creativity and “slowly making sense of the world” (Page 95).
- The book correctly identifies the multicausality of the attention crisis. It’s not just phones; it’s also chronic stress, trauma, and financial insecurity (Page 172, 181). These factors induce “hypervigilance,” where the brain is constantly “scanning for unexpected dangers” (Page 134, 175) and cannot achieve deep focus.
- The analogy of a zoo animal is a powerful example of the trait adaptivity model. Like a polar bear pacing in its enclosure, many attention problems (like ADHD) may not be a “disease” but a natural response to ‘”frustrated biological objectives”‘ (Page 219) and an environment we aren’t built for.
- The book heavily emphasizes the sleep mental model. Staying awake for nineteen hours leaves you “as cognitively impaired as if you had gotten drunk” (Page 66) because the brain needs sleep to perform its “brainwashing” function of cleaning out toxins (Page 72).
You should buy a copy of Stolen Focus if: you ever feel like you have trouble paying attention… or see your kids/grandkids glued to their screens.

More Detailed Notes + Analysis (SPOILERS BELOW):
IMPORTANT: the below commentary DOES NOT SUBSTITUTE for READING THE BOOK.
Page 8: The author describes his personal realization that his attention was “fracturing.” While trying to be present with his godson, Adam, he felt himself “losing my ability to be present.” His godson noticed, saying, “‘I know something’s wrong… But I have no idea how to fix it.'” The author realized “there was no escape, because this problem was everywhere,” noting even Iceland’s Blue Lagoon was full of people “frantically posting to Instagram.”
Page 9: The author interviews Professor Roy Baumeister, a leading expert on willpower, who confesses his own struggles. Baumeister states: “‘I’m feeling like my control over my attention is weaker than it used to be.'” He explains that he used to read for hours, but now “‘it seems like my mind jumps around a lot more,'” and he finds himself turning to phone games when he feels bad, “just sort of giving in to it.” This highlights the challenge of maintaining willpower in the modern environment – even for someone who has studied it for more than thirty years!
Page 15: The author states his thesis that this attention crisis “is human-made, and it can be unmade by us too.” He explains his research method involved interviewing both neuroscientists and social scientists, who “analyze how changes in the way we live affect us.” He acknowledges that humans are complex and the science is “fallible and fragile,” but he “had to proceed… on the basis of the best information we have,” seeking a “broad consensus” where possible. I like the way he thinks about this.
Page 21: Describes the common reactions of panic and envy when the author told people he was giving up his smartphone. People worried about emergencies but also “began to fantasize about what they would do with all the time” that was freed up. The habitual nature of phone use is underscored by data showing the average American touches their phone “2,617 times every twenty-four hours.”
Page 22: Explains the “Ulysses” technique of pre-commitment, a core concept in the Planner-Doer model. Just as Ulysses had his crew “tie him to the mast,” the present “Planner” version of you must bind the future “Doer” who will face temptation. The author used this himself: “So I stopped buying [carbs].” Research confirms this works; a study found that men who “pre-committed” to waiting for a better reward were “strikingly successful” compared to those who relied on willpower alone. An example of the commitment bias mental model and activation energy mental model.
Page 27: The author describes his “haze of decompression” during his digital detox. He contrasts the social connection of singing show tunes in a pub with strangers versus online interaction, noting the former “dissolves your sense of ego; the second jabs and pokes at it.” After a week of this stillness and connection, he “fell into the deepest sleep I could remember,” waking 15 hours later.
Page 30: Details the scientific study by Sune Lehmann on collective attention spans. His team analyzed Twitter data to see how long a topic stays in discussion. They found that in 2013, a top hashtag “would remain… for 17.5 hours.” By 2016, “that had dropped to 11.9 hours.” Similar analysis conducted across Reddit, Google, movie ticket sales, and so on suggest that “as time passed, we were focusing less on any one individual topic.”
Page 31: Sune Lehmann’s team expanded their study and found the same accelerating trend everywhere. By analyzing Google Books from the 1880s, they discovered that “with each decade that passed, for more than 130 years, topics have come and gone faster and faster.” This was crucial, as it proved that while the internet “had rapidly accelerated the trend,” it was not the “sole cause” of shrinking collective attention. At the same time, “something is changing… it’s not just the same-old, same-old.”
Page 32: Identifies the primary cause of shrinking attention spans: information overload. Sune Lehmann’s model found “one mechanism that will make this happen every time: You just have to flood the system with information.” The more information, the less focus on any one piece. We are “‘drinking from a fire hose.'” This is quantified by other research showing daily information consumption rose from “the equivalent of 40 newspapers” in 1986 to “174 newspapers” by 2007. Obviously, things have not gotten better for our poor brains since 2007.
Page 33: Explores the tradeoff of information overload, which is the loss of “depth.” Sune Lehmann argues that “what we are sacrificing is depth in all sorts of dimensions.” Depth “takes time. And depth takes reflection,” but if you are constantly keeping up with emails, “there’s no time to reach depth.” This sacrifice pulls us “more and more up onto the surface.” Hari concludes his detox allowed him to finally live “within the limits of my attention’s resources.” One line that jumps out to me: “We are, collectively, experiencing a more rapid exhaustion of attention resources… [when I detoxed], I realized… I was, for the first time in my life, living within the limits of my attention’s resources. I was absorbing as much information as I could actually process, think about, and contemplate – and no more. The fire hose of information was turned off. Instead, I was sipping water at the pace I chose.”
Page 35: Debunks the myth of speed-reading, explaining that scientific tests show “the less they will understand. More speed means less comprehension.” This focus on speed (a form of busyness over productivity) means people are “much less likely to grapple with complex or challenging material.” The author observes this in his own online reading, where he skims complex topics and clicks on “simpler, more scannable stories.” Ultimately, “there’s just a maximum limit for how quickly humans can absorb information, and trying to bust through that barrier simply busts your brain’s ability to understand it instead.”
Page 36: Explains how slowness can heal attention. Professor Guy Claxton’s research on practices like mindfulness and yoga shows they “improve your ability to pay attention by a significant amount.” Claxton states, “‘If you go too fast, you overload your abilities, and they degrade.'” He argues that slowness nurtures attention while speed shatters it. I particularly like: “it’s not about humming or wearing orange robes.” Rather, “we have to shrink the world to fit our cognitive bandwidth.”
Page 37: Professor Earl Miller explains the fundamental bottleneck of the human brain, which debunks the myth of multitasking. He states bluntly: “Your brain can only produce one or two thoughts in your conscious mind at once. That’s it.” We have a “very limited cognitive capacity” due to the “fundamental structure of the brain,” but we have fallen for the “enormous delusion” that we can think about many things at the same time. He notes the contrast between brains and processors – see Tae Kim’s The Nvidia Way for more; my own analogy is that our brains are more like CPUs (cannot operate efficiently in parallel) vs GPUs (can operate massively parallel).
Page 38: Explains that what we call “multitasking” is, in reality, rapid “task-switching.” When people think they are doing several things at once, “they’re actually… ‘juggling.’ They’re switching back and forth.” This process is not seamless and “comes with a cost” known as the “switch-cost effect.” Every time you switch, your “brain has to reconfigure,” and you must “remember what you were doing before,” which degrades your ability to focus.
Page 39: Outlines the three high costs of task-switching. First is wasted time (“wasted brain-time”). Second is the “screw-up effect,” as “your brain is error-prone” when switching and you thus have to spend more time “correcting errors and backtracking”. Third is the “creativity drain.” The cost is not trivial: one study found that simple “technological distraction” from emails and calls caused an “average drop in the workers’ IQ by… ten points,” which is “twice the knock… you get when you smoke cannabis.”
Page 40: Explains the “creativity drain” and “diminished memory” effects of task-switching. Creativity requires “free undistracted time” for the brain to form new connections; this is lost to “switching and error-correcting.” This discussion aligns directly with Alex Soojung-Kim Pang’s focus in Rest on the Default Mode Network (DMN). Pang explains that the DMN is highly active when one is not hyper-focused and is correlated with capacities like memory, imagination, empathy, and intelligence, often facilitating major breakthroughs that occur when individuals are not actively concentrating on a problem. Furthermore, a UCLA study demonstrated the memory cost: people who performed two tasks simultaneously “couldn’t remember what they had done as well as people who did just one thing at a time.”
Page 41: Illustrates the high cost of interruptions, which are often mislabeled as “multitasking.” Most office workers never get an hour to themselves, and even having a phone on is a form of switching. This has a measurable cost: a Carnegie Mellon study found students who received intermittent text messages “performed, on average, 20 percent worse” on a test. The author suggests “almost all of us with a smartphone are losing that 20 to 30 percent, almost all the time.” This demonstrates the myth of multitasking.
Page 42: Persistent distractions can have “as bad an effect on your driving as if you were drunk.” This highlights the “Human” limits of our brains, which “hasn’t significantly changed in 40,000 years,” even though the average teen “genuinely believes they can follow six or seven forms of media at once.” Johann notes that “We are not machines. We cannot live by the logic of machines. We are humans, and we work differently.”S Again, see The Nvidia Way – we think of our brains as GPUs but they’re really more like CPUs. Professor Miller concludes we are living in a “‘perfect storm of cognitive degradation.'”
Page 43: Professor Earl Miller notes “the brain is like a muscle. The more you use certain things, the stronger the connection’s getting, and the better things work.” We have to train attention. Skipping ahead a bit, I love Johann Hari’s money-quote on page 273, which I use as a keystone of the mental model: “For a long time, we took our attention for granted, as if it was a cactus that would grow even in the most desiccated climate. Now we know it’s more like an orchid, a plant that requires great care, or it will wither.”
Page 44: Uses Adam Gazzaley’s metaphor of the prefrontal cortex as a “bouncer” to explain the brain’s bottleneck. The bouncer can only handle “one or two people… at a time.” Today, with constant distractions like noise pollution (“children in noisy classrooms have worse attention than kids in quiet classrooms”), the bouncer is “besieged” and “exhausted.” When the bouncer is overwhelmed and “can’t filter like he used to,” the “nightclub of your mind becomes full of rowdy assholes.” Hari points to open-plan offices, crowded cities, and so on as “shrieking distractions calling for our attention” (which is one reason I’m a huge proponent of remote work; the supposed collaboration that happens in an office is usually outweighed by all this).
Page 49: Describes the power of internal, habitual interruptions. Even after removing external distractions, you “will start to interrupt yourself,” constantly “imagining how I would describe [things] in a tweet.” He missed the “thin, insistent signals of the web” that provided a sense of validation – that he had, over time, “derived a large part of meaning in my life.” He notes “no stranger is going to flood you with hearts and tell you you’re great” – an example of the trait adaptivity mental model combined with the social proof mental model, i.e. how the need for social validation (highly adaptive in human evolution / history) is now being hijacked by social media. “The absence of these insistent signals seemed to suggest an absence of meaning.”
Page 53: Describes the behaviorist psychology of B.F. Skinner, which is the foundation for many social media mechanics. Skinner believed humans “have no minds… with free will” but are just “the sum total of all the reinforcements” in their lives. This conditioning logic was applied by tech designers: “If we reinforce our users for selfies… will they start to do it obsessively?” Mihaly Csikszentmihalyi found this view “bleak and limited,” as it missed positive human psychology.
Page 54: Mihaly Csikszentmihalyi studied artists to understand “flow.” He observed them in a “deep form of attention” and found something that contradicted B.F. Skinner’s incentive-based theories: the artists were not motivated by the reward. “Almost all of them simply put the painting away and started working on another one.” He realized what was “enthralling” was “the process of painting itself,” a state he also found in people doing difficult activities like rock climbing “for no obvious reward.” Mihaly’s work is referenced in many other books on PAA, although I don’t think I have a formal review of the book up on the site.
Page 56: Outlines the three conditions required to achieve a state of flow. First is monotasking: “Flow can only come… when you set aside distraction,” as multitasking kills it. Second, the goal must be meaningful, because “we pay attention to things that are meaningful to us.” Trying to focus on something meaningless requires brute force. Third, the task must be at the “edge of your abilities” i.e. not so easy you’re on autopilot, and not so hard you become anxious. The money quote, from Roy Baumeister: “A frog will look at a fly it can eat much more than a stone it can’t eat… this goes back to the design of the brain. It’s designed to pay attention to the stuff that matters to you.” Johann’s commentary: “In any situation, it will be easier to pay attention to things that are meaningful to you, and harder to pay attention to things that seem meaningless. When you are trying to make yourself do something that lacks meaning, your attention will often slip and slide off it.”
Page 57: Flow is a “distinctive mental state” where “your ego has vanished” and “you feel merged with the task.” Mihaly’s work established “positive psychology” (see our discussion of Shawn Achor’s The Happiness Advantage) which focuses “on the things that make life worth living,” as a counter to Skinner’s manipulative vision. Today, Skinner’s vision dominates our technology, and here’s another money quote: “Many of us are like those birds in cages being made to perform a bizarre dance to get rewards.”
Page 58: Another money quote: “When we are not focusing, we are not using one of our greatest capacities. Starved of flow, we become stumps of ourselves, sensing somewhere what we might have been.”
Page 59: Flow states are “extraordinarily fragile and easily disrupted,” and research from the 1980s showed “staring at a screen… provides on average the lowest amount of flow.” The key to escaping distraction is not just removing the negative; you must also cultivate agency by setting a positive goal. As Mihaly explained, “‘We also need a positive goal, otherwise where are you going?'” Without a positive goal, “you will be pulled back to distraction sooner or later.”
Page 61: Hari describes the profound relief of his attention returning after weeks of digital detox: “It came back! My brain came back! I feared my brain had been broken… but I could see now that healing was possible.” He felt as though the internet had been a “vast weight on my back, and I had sloughed it off.” Of course, as a socialist, he can’t simply accept that human agency is real and that people should be responsible for their own behavior, so he launches into a tedious discussion of how privileged he is.
Page 66: Details Charles Czeisler’s research on the cumulative effect of sleep deprivation. He found that as people were kept awake, “their ability to focus fell off a cliff.” He discovered that staying awake for nineteen hours straight leaves you “as cognitively impaired as if you had gotten drunk.” This is critical, as he warns 40 percent of Americans are chronically sleep-deprived, getting less than the seven-hour minimum. This directly supports the sleep mental model (again, see Matthew Walker’s Why We Sleep for more).
Page 67: Details the findings of Charles Czeisler on sleep deprivation, a core component of the sleep model. As you become tired, your attention “blinks out” due to a state called “local sleep,” where “‘part of the brain is awake, and part of the brain is asleep.'” In this state, you believe you are alert, but “parts of your brain are asleep.” He notes that when adults get drowsy from sleep loss, kids often get hyperactive, “exhibiting all the symptoms of deficiency” like an inability to pay attention.
Page 68: Professor Roxanne Prichard’s research shows college students are profoundly sleep-deprived, often “visibly exhausted and struggling to stay awake.” She found the average student “has the same sleep quality as an active-duty soldier or a parent of a newborn baby.” This has become a cultural default; students are so “accustomed to that since puberty” that they view this exhaustion as “a state of normal.” This lack of sleep directly correlates with slower reaction times. “They’ve grown up being accustomed to being exhausted and trying to medicate that away as a state of normal. So I’m fighting against a current that says it’s normal to be exhausted all the time.”
Page 72: Describes the critical “brainwashing” that occurs only during sleep, a key part of the sleep mental model. (See also our review of Dr. Matthew Walker’s Why We Sleep, which goes in a lot more depth on this.) The brain cleans out toxins, or “brain-cell poop,” which explains “why, when you are tired, you can’t focus well.” Dr. Maiken Nedergaard uses an analogy: “The brain […] must choose between two different functional states – awake and aware, or asleep and cleaning up […] You can either entertain the guests or clean up the house, but you can’t really do both at the same time.” A brain that hasn’t been cleaned becomes “clogged.”
Page 77: Hari recommends that “your phone should always recharge overnight in a different room, where you can’t see it or hear it.” This is a profoundly stupid and unsafe idea. Some sort of phone should ideally always be within reach. Hari seems blithely unaware that emergencies exist (he hand-waved them away earlier with his P-town detox, as well as later in the book when he talks about kids wandering around unsupervised). I’m obviously not a fan of the BS “grit” approach to life (again, see the willpower mental model), but this is an area where you should just use a little willpower or activation energy – put it in a drawer in your bedside table or something (so that in an emergency such as the house being on fire, you can call 911 instead of dying – or vice versa if a family member needs you.)
Page 80: Documents the decline of book reading, which is a common form of “flow.” The proportion of Americans reading for pleasure is at its “lowest level ever recorded,” with the share of men reading for pleasure falling “by 40 percent” between 2004 and 2017. Money statistic: the average American now spends “seventeen minutes a day reading books and 5.4 hours on their phone.”
Page 81: Professor Anne Mangen’s research shows that the medium of reading trains our brain. “Reading from books trains us to read in a particular way – in a linear fashion.” In contrast, reading from screens “trains us to read in a different way – in a manic slip and jump.” We “‘scan and skim'” on screens, and this becomes a new habit. Mangen warns, “‘this scanning behavior also becomes our default'” even when reading on paper. Of course, for work purposes, reading on paper is a really dumb idea (particularly in the age of AI) – but long-form reading clearly has its benefits.
Page 82: Highlights the concept of “screen inferiority,” which is supported by “broad scientific” evidence from fifty-four studies. This research shows that “people understand and remember less of what they absorb on screens” compared to paper. This comprehension gap is significant; in children, “it’s the equivalent of two-thirds of a year’s growth in comprehension.” Anne Mangen worries we are losing the “‘cognitive patience [and] the stamina'” to deal with complex texts. Another money quote: “I started to wonder what happens to a world where this form of deep focus shrinks so far and so fast. What happens when that deepest layer of thinking becomes available to fewer and fewer people, until it is a small minority interest, like opera, or volleyball?”
Pages 83-84: Hari provides a very powerful synthesis here. Money quote time! He asks “What is th[e] message [of Twitter?] First, you shouldn’t focus on any one thing for long. The world can and should be understood in short, simple statements of 280 characters. Second: the world should be interpreted and confidently understood very quickly. Third: what matters most is whether people immediately agree with and applaud your short, simple, speedy statements. A successful statement is one that lots of people immediately applaud; an unsuccessful statement is one that people immediately ignore or condemn. When you tweet, before you say anything else, you are saying that at some level you agree with these three premises. You are putting on goggles and seeing the world through them.” A lot of mental models here – schema, social proof, habit, etc. He does the same sort of analysis for Facebook and Instagram (I shudder to think what TikTok would come out as). he then has yet another money quote: “I realized one of the key reasons why social media makes me feel so out of joint with the world, and with myself. I think all of these ideas – the messages implicit in these mediums – are wrong…. the world is complex. To reflect that honestly, you usually need to focus on one thing for a significant amount of time, and you need space to speak at length. Very few things worth saying can be explained in 280 characters.”
Page 85: Contrasts the “medium” of social media with the “medium” of the book. The book’s medium conveys the opposite: money quote time! “life is complex; and if you want to understand it, you have to set aside a fair bit of time to think deeply about it.” The book values “narrowing down your attention to one thing” and understanding that other people “have complex lives just like you.”
Page 86: Discusses the research of Professor Raymond Mar on how reading fiction builds empathy. His mentor, Keith Oatley, hypothesized that when you read a novel, “you are immersing yourself in what it’s like to be inside another person’s head.” This acts as a “social simulation,” training your ability to understand other people. This supports the author’s feeling that he is a “better, calmer, and deeper” person when he reads. Hari calls fiction “a kind of empathy gym.”
Page 88: Reading fiction requires a unique combination of outward attention (on the words) and “inwardly directed attention,” where the reader must “imagine what it is like to be another person.” This process acts as a “virtual simulator,” providing “practice” for the “cognitive processes that… we would use to understand… real peers.” This suggests that reading complex narratives can have an empathy-expanding effect. He notes “each of us can only ever experience a small sliver of what it’s like to be a human being alive today… but as you read fiction, you see inside other people’s experiences. That doesn’t vanish when you put down the novel. When you later meet a person in the real world, you’ll be better able to imagine what it’s like to be them.”
Page 89: While it’s debated whether empathetic people are simply drawn to fiction, studies suggest reading stories “really does boost their empathy.” This benefit isn’t limited to print; TV series can be effective if they present a “complex narrative that simulates the world.” However, shorter forms of media, like social media, often fail to engage this process: “if you see the world through fragments, empathy doesn’t kick in, in the way that it does when you engage with something in a sustained, focused way.” That’s a money quote. Here’s another: “the more a chidl is read storybooks… the better they are at reading other people’s emotions.”
Page 92: The common understanding of attention is the “spotlight” model: the “ability to selectively attend to one thing” and filter out distractions. However, this is “only one form of attention that exists,” and it coexists with other forms that are “just as essential.” An over-reliance on the spotlight and constant stimulation can lead to a state of panic, like the “urge to check” a phone or never “just sit for six hours” without filling the time. This hints at the different modes of cognition and intuition.
Page 95: Scientific research has surged into “mind-wandering,” often associated with the “default mode network.” (See also Rest by Alex Soojung-Kim Pang.) This state is not a failure of attention but a crucial process. One key function is that “you are slowly making sense of the world.” For example, while reading, “a little bit of your mind… is wandering,” connecting the text to “your own life” or other parts of the book. This isn’t a distraction; “This isn’t a flaw in your reading. This is reading.”
Page 96: Mind-wandering is essential for making long-term decisions and “to make sense of your life.” A second benefit is creativity: “when your mind wanders, it starts to make connections between things… which often produces solutions.” This is exemplified by the mathematician Henri Poincaré, who couldn’t solve a problem with narrow “spotlight” focus, but “when he let his mind wander,” found the solution. Hari notes “in fact, when you look back over the history of science and engineering, many great breakthroughs don’t happen during periods of focus – they happen during mind-wandering.” See also the invention book, How We Got To Now. A new framing of creativity: “creativity is not where you create some new thing that’s emerged from your brain. It’s a new association between two things that were already there.”
Page 97: A third function of mind-wandering is “mental time-travel,” where the brain “roams over the past” and “tries to predict what might come next.” This is not a failure of attention but “a different form of attention.” When the spotlight turns off, “it’s not like attention… necessarily goes down it just shifts to other, crucial forms of thinking.” This contradicts our cultural belief that only “spotlight-focused” work is productive, and that mind-wandering is “slacking” or “being lazy.” Money quote time (I circled this and wrote lots of explanation points): “This, I realized, is quite challenging to the whole way I had been raised to think about productivity. I feel instinctively like I’ve done a good hard day of work when I have been sitting at my laptop, spotlight-focused on tapping out words. At the end of it, I feel a little Puritan rush of pride at my productivity. Our whole culture is built around this belief. Your boss wants to see you sitting at your desk every hour of the day; this is what she thinks work is. This way of thinking is implanted in us from a very young age when… we are told off at school for daydreaming.” A lot of mental models here – product vs. packaging, nonlinearity, culture, etc.
Page 98: Spotlight focus provides the “raw material,” but at some point, “you need to stand back” and let the mind “digest” it. This reminds me a bit of John Lewis Gaddis and The Landscape of History. “If we were just frantically running around on the external world exclusively; we miss the opportunity to let the brain digest.” Today’s digital environment, full of constant switching, creates an “unsatisfying” state where “we’re not focusing, but we’re not mind-wandering either.” We are facing a crisis of “degrading” both forms of attention. “We’re constantly skimming, an unsatisfying whir.” (Money quote.)
Page 107: The art of magic is not about fooling intelligence; it is “about the weaknesses… the blind spots” in human cognition. “Magic, in other words, is the study of the limits of the human mind.” We believe we control our attention, but “in reality we are fallible sacks of meat… in predictable ways.” A magician can “manipulate your attention” while making you believe you are “simply using your own free will,” exploiting these inherent cognitive biases.
Page 108: Magicians can exploit cognitive weaknesses, “subtly guiding” a person’s choices, for example, by shifting their eyes while the person remains unaware. This demonstrates a core insight: “you can manipulate people and they don’t even know it’s happening.” This same understanding of human “weaknesses” was being studied by another group with different goals: technology designers at Stanford. (Relates to Thaler and Sunstein’s Nudge, which is one of our favorite books.)
Page 113: Beaten to death a bit, but again, the money quote: “the incentives seemed to lead only one way: you should always design products that “engage’ the maximum number of people, because engagement equals more dollars, and disengagement equals fewer dollars.”
Page 114: Working inside Google, Tristan Harris realized users’ dwindling focus wasn’t a personal failing: “It’s not your fault… It’s by design. Your distraction is their fuel.” The tech industry is “caught in this arms race to manipulate human nature,” which is a zero-sum game for attention. This design fits the N-order consequences mental model, such as Instagram filters creating a “whole category of people who undergo surgery” to match their filtered appearance. Dating apps could be another example here.
Page 115: Recounts Tristan Harris’s internal Google presentation questioning the company’s impact on focus. He worried they were “‘destroy[ing] our kids’ ability to focus'” and asked, “Why are we finding better and better ways to ramp up the interruptions?” He proposed using choice architecture to fix this, such as batching emails so it felt like “getting a newspaper in the morning, instead of constantly following the news.” Particularly troubling: “the average child between the ages of thirteen and seventeen in the U.S. was sending one text message every six minutes they were awake. People were, he warned, living ‘on a treadmill of continuous checking.'”
Page 117: Snapchat streaks weaponize adolescents’ high need for social connection. “It was a perfect way to take the desire of teens for social connection and manipulate it to get them hooked. You came every day to extend your streak, and you stuck around to scroll, often for hours.”
Page 118: Damage to attention spans is not a deliberate goal but an “inescapable effect of their current business model.” The system is driven by powerful incentives; telling Google to “make human attention spans… better” is like telling an oil company “not to drill for oil.” “Telling them to distract people less was like telling an oil company not to drill for oil.” Money quote.
Page 120: Aza Raskin explains his invention of infinite scroll, a form of negative choice architecture. It was designed to remove the pause where a user had to make an “active choice” to click to the next page. Instead, “it will automatically load another chunk for you to flick through… forever.” He was initially proud, but later calculated this design was draining “many human lifetimes” of attention every single day. As do many of us: “He found himself infinitely scrolling through what he often realized afterward was crap, and he wondered if he was making good use of his life.”
Page 121: The inventor of infinite scroll, Aza Raskin, describes his growing discomfort with his creation. He once believed “making something easy to use meant the world would be better,” but came to realize “making something easy to use doesn’t mean it’s good for humanity.” He saw the massive unintended consequences of his design, which was pulling people’s time away from their family. This was reinforced by the incentives of investors, who only wanted to know: “How much of people’s attention do you capture?”
Page 122: He notes the irony of Facebook and Google having workshops like mindfulness when they are “the biggest perpetrators of non-mindfulness in the world.”
Page 123: Many Silicon Valley insiders who built these systems express deep regret. Facebook’s former VP of growth, Chamath Palihapitiya, said his own kids “aren’t allowed to use that shit.” The co-inventor of the iPhone, Tony Fadell, said he wakes up in “cold sweats thinking, what did we bring to the world?” When one former Google strategist asked an audience of tech designers, “How many of you want to live in the world you are designing?”… “Nobody put up their hand.”
Page 125: The business model is simple: “Facebook makes more money for every extra second you are staring at their site, and lose money every time you log off.” This incentive is served in two ways: showing more advertisements and, more subtly, scanning and sorting user data. “Companies are building up a… profile of you, to… target you,” turning private correspondence into an “advertising profile.”
Page 126: This data collection builds a predictive model, described by Aza Raskin as a “voodoo doll.” He explains, “inside of Google’s servers, there… is a model of you.” The company tests stimuli against this model to see what “makes its arm twitch and move,” and then serves that content to the user. As these predictive models get “more sophisticated every year,” their accuracy “is starting to look like magic.” Aza notes: “It’s getting to be so good that… I’ll ask the audience how many think Facebook is listening to their conversations, because there’s some ad that’s been esrved that’s just too accurate… [they mentioned offline.] The truth is creepier – it’s not that they are listening… it’s that their model of you is so accurate that it’s making predictions about you that you think are magic.” Money quote, and also a really interesting parallel to AI that I’ll get into later.
Page 127: This business model, coined “surveillance capitalism” by Harvard professor Shoshana Zuboff, is built on predicting and influencing human behavior. It explains why a feature that encourages users to log off and meet “face-to-face” would be a “catastrophe” for the company’s stock price. The incentives are clear: “These sites are designed to be maximally distracting. They are designed to distract us… to make more money.”
Page 128: The tech industry’s incentive structure means that any engineer who “proposes a choice that improves people’s attention” will be overruled if it causes “time [on site]… [to] go down.” The core issue is that “Their business model is screen time, not life time.” The problem is not the smartphone “itself,” but the “apps that run on them” which are “deliberately designed… to grab and hold our attention.”
Page 129: The current, distracting design of technology is a “choice,” not an inevitability. “You could design the technology… with the opposite goal: to maximally respect people’s need for sustained attention, and to interrupt them as little as possible.” The problem is not the internet itself, but the “incentives for designing it.” This suggests a choice architecture solution is possible, shifting the debate from “pro-tech” vs. “anti-tech” to “What tech, designed for what purposes, in whose interests?”
Page 130: What users see on social media is not random but “selected… according to an algorithm.” This algorithm isn’t designed to make you happy or informed; it “has one key driving principle… It shows you things that will keep you looking at your screen.” This creates a powerful incentive to promote content that makes people “angry and outraged,” as that is often more engaging than calm or neutral updates.
Page 131: The algorithm doesn’t care about user well-being, it “only cares about one question: Will you keep scrolling?” This exploits a natural human quirk known as “negativity bias.” “On average, you will stare a lot longer at something negative and outrageous… than… at something positive and calm.” This is a form of salience bias. Consequently, an algorithm designed to maximize engagement will “inevitably… prioritize outraging and angering you,” rewarding words like “hates,” “slams,” and “destroys.” (Loss aversion mental model.)
Page 133: Social media platforms are designed to condition users through immediate, frequent rewards (like retweets or likes), which creates a craving that “will drive you to pick up your phone.” This is a big trait adaptivity mental model issue – we’re being hijacked by challenges we’re not adapted to solve. Money quote: “all the costs to your attention caused by switching… is as bad for the quality of your thinking as getting drunk or stoned.” These sites “frack” users by learning their specific personal triggers—what excites or enrages them—to “drill into your attention.” The algorithm is “drip-feeding you the kind of material that it has learned… keeps you scrolling.” Anger is a key tool, as “anger itself screws with your ability to pay attention” and results in a “‘decreased depth of processing’.” This is a powerful example of the habit formation loop being exploited by platform incentives.
Page 134: The algorithms promote content that makes users feel “surrounded by other people’s anger.” This activates a threat response, similar to if you “are attacked by a bear.” When this happens, your attention “flips to scanning for unexpected dangers” rather than focusing on normal, everyday concerns. The platforms make you “feel that you are in an environment full of hostility,” causing you to become “more vigilant.” This state of high alert, a form of stress response, makes attention unavailable for slower, deeper tasks.
Pages 136-137: I really wish TikTok had been banned… he doesn’t mention it specifically here, but “the average young person is soaking up filth like this day after day. Do those feelings of anger go away when they put down their phone?” Discusses YouTube’s radicalizing algorithm, quoting Tristan Harris who reframes the problem from “a few bad apples” to a systemic issue. He asks: “‘Do we have a system that is systematically, as you turn the crank every day, pumping out more radicalization?'” He calls the platform a “bad-apple farm,” highlighting the dangerous second-order consequences of an incentive system built purely for engagement.
Page 145: Nir Eyal, author of Indistractible, argues for individual agency and responsibility. He believes individuals are “‘the first line of defense'” and that change “‘has to begin with introspection.'” While it’s “not your fault,” he argues “it’s your responsibility” because “‘We have to adapt.'” Eyal’s method focuses on identifying “‘internal triggers'” that lead to distraction. For him, the trigger was feeling “‘bored or stressed'” while writing. This “‘uncomfortable emotional state'” would cause him to seek an escape, like telling himself “‘Let me just open my email real quick,'” which would inevitably lead him “‘at the bottom of a rabbit hole, looking at something totally irrelevant.'”
Page 147: While the author found Eyal’s individual tips “‘made a small but real difference,'” he became uncomfortable with the overall framing. He realized “‘Nir’s approach is absolutely in line with how the tech companies want us to think about our attention problems.'” By “subtly urging us to see it as an individual problem,” the companies shift the burden of “self-restraint on our part… not theirs.” Of course, agency exists. Eyal is right and Hari is wrong.
Page 150: Professor Ronald Purser critiques the individual-only approach using the concept of “‘cruel optimism.'” This is defined as when “‘you take a problem with really big, deep causes in our culture… and you offer people a simplistic, individual solution.'” It is “cruel” because the solution is so limited that “‘for most people, it will fail.'” An example is given of a bestselling book on stress that claims “‘Stress isn’t something imposed on us. Stress is something we impose on ourselves.'” This book’s solution is simply to meditate and “‘learn to think differently,'” ignoring the structural causes of stress. I strongly disagree – as, I think, would Rob Henderson in Troubled – although I end up in the middle of Rob and Johann given that Johann is pretty far left, whereas Rob makes the case for social conservatism to solve some of these same issues.
Page 152: Critiques the “cruel optimism” of individual-only solutions. This view blames the user, but “it’s not so easy for everyone” to simply meditate or use willpower. “It’s easier to find serenity through meditation when you haven’t just lost your job.” Telling people to just “push the fucking button” is to “deny the reality for most people’s lives.” Hari argues we must challenge the systems, asking, “Why should we accept the systems as a given?”nbsp; Although I’m a big proponent of the structural problem solving mental model, Johann Hari allows his politics to get in the way of reality here – people have agency, and we should utilize it. Belief behavior matters.
Page 153: The obesity crisis provides a powerful analogy for the attention crisis. (Johann’s book on GLP-1s is good, although not my favorite.) Anyway: according to Hari, the problem wasn’t a sudden failure of individual willpower; the environment changed en masse. We “‘replaced our food supply with… processed junk'” and “‘built cities that are… impossible to walk or bike around.'” Relying only on willpower in a broken system is “‘like trying to run up an escalator that’s coming down.'”
Page 158: I have written in the margins here “if there is no product, you are the product.” There’s also an illegible word that looks like “Tansdavl.” I have no idea what this means. Anyway, Hari goes on to – again, laughably – argue fortunately, there’s a better option. You can have public ownership, independent of the government.” My note here is much easier: “is it, though?”
Page 159: Aza Raskin explains how social media sites could be technically redesigned to be less harmful, using choice architecture. For instance, Facebook could “batch” notifications, so as Hari puts it, “instead of getting ‘this constant drip of behavioral cocaine,’… you would get one daily update, like a newspaper.” Raskin also suggests turning off infinite scroll (his invention) which “catch[es] your impulses before your brain has a change to really get involved and make a decision” so that users must make a “conscious decision to carry on” rather than being passively and endlessly pulled into more content.
Page 164: Cites leaked internal Facebook documents showing the company’s own scientists knew its incentive system was harmful. One report concluded: “‘Our algorithms exploit the human brain’s attraction to divisiveness.'” It warned that “‘if left unchecked,'” the algorithm would “pump its users with more and more divisive content” to maximize attention. Another internal study found 64 percent of all people joining extremist groups did so because the algorithm recommended them. However, Hari again veers into socialism, advocating extreme regulation of Big Tech. In a laughable sentence, he mentions “.. those companies have in some way been taken over as public utilities run in our collective interests, like the sewers or the highways.” Given that the government already pressured social media into censorship during COVID – the n-order impacts mental model rings quite clear here; Hari seems blissfully unaware of the various First Amendment issues with the government telling communications platforms how to run. I’m not saying the current situation is good (it’s not), but it seems very much a “out of the frying pan, into the fire” situation.
Page 172: The book argues for multicausality in the attention crisis. A study asking people why their “‘attention was getting worse'” found the “‘number-one reason… was not their phones. It was stress.'” The second and third reasons were “‘a change in life circumstances'” and “‘difficult or disturbed sleep.'” I’ve definitely had both of these issues at various points in time. In fact, “‘Phones came fourth.'” This suggests there are “‘deeper forces… [which] led us, in turn, to develop a dysfunctional relationship with the web.'”
Page 174: Dr. Nadine’s breakthrough came from treating a boy with severe attention problems. His issues started when he was sent to live with his father after being sexually abused by his mother’s boyfriend. (See Troubled by Rob Henderson on the impact of broken families.) Nadine observed that kids in poorer neighborhoods were “‘being diagnosed'” with attention issues at a “‘dramatically higher rate.'” This led her to question the root cause and disaggregate the problem, wondering if chronic stress and trauma were being misdiagnosed:
Page 175: Introduces the concept of “hypervigilance” using the analogy of a bear attack. When the brain perceives constant danger, it enters a state where its attention ‘is focused on cues for potential danger’ rather than the present task, like learning math. This isn’t a failure of attention; rather, ‘they’re paying attention to any cues or signs of threat or danger in their environment.’ Nadine Burke Harris notes this is a ‘natural and necessary response’ to ‘intolerable circumstances’, which links directly to the stress mental model where perceived threats hijack focus. It’s a trait adaptivity mental model issue.
Page 176: Explores the link between childhood trauma and attention issues. Research by Nadine Harris found that children with four or more types of trauma “were 32.6 times more likely to have been diagnosed with learning or behavior problems.” This is supported by other studies showing trauma triples ADHD symptoms. The underlying principle is that focus requires safety: “To develop attention in normal ways, you need to feel safe,” as you must be able to switch off the vigilant part of your mind that scans for danger. This is a core part of the stress and cognition model. See also Rob Henderson’s Troubled.
Page 177: Argues that medicating children experiencing hypervigilance due to trauma is a serious error. As Nadine Burke Harris told Johann Hari, ‘Guess what? Ritalin does not treat sexual assault.’ The page notes that sexual-abuse survivors had ‘double the usual rate of diagnosable ADHD.’
Page 178: The solution to trauma-induced attention issues is not medication but changing the environment. Nadine Burke Harris explains the need to ‘create an environment… that is not scary or stressful’ and ‘layer on lots of buffering, and lots of nurturing caregiving’. At the same time, Hari once again discounts agency, i.e. “you can’t choose where you come from, but you can choose where you go from there.” Again, see Rob Henderson’s Troubled.
Page 180: While mild stress can briefly improve performance, the evidence is clear that ‘protracted levels of stress can significantly undermine attention’. This kind of stress can cause structural changes in the brain. It also triggers other issues, like insomnia, which itself ‘isn’t a malfunction—it’s an adaptive trait’ in response to perceived danger. (Trait adaptivity mental model.) The text points to financial insecurity as a major source of this protracted stress, noting ‘Six out of ten U.S. citizens have less than $500 in savings’.
Page 181: Financial stress directly impacts cognitive ability. A study of sugarcane harvesters in India found their measured IQ was ‘thirteen points’ higher after the harvest (when financially secure) than before (when broke). ‘When you are worried about how to survive financially… You become more vigilant, just like Nadine’s patients.’
Page 182: The Finnish basic income experiment found that ‘once people received the income, their ability to focus improved dramatically’. The researchers concluded: ‘If you have to worry about your financial situation… it takes a lot of your brain capacity.’ Again, Hari doesn’t really think about the n-order impacts mental model here, or even the incentives mental model.
Pages 186 – 187: Describes an experiment at Perpetual Guardian in New Zealand that trialed a four-day work week for five days’ pay. The hypothesis was that “giving people time to rest and enjoy life might mean they worked more productively when they were in the office.” Despite managerial skepticism – “[the] head of HR literally fell over” – the trial was implemented for two months. It worked; an employee noted “I was less likely to be distracted.” This challenges the standard structure of work, suggesting that rest is crucial for productivity, a key idea in the mental model of rest.
Page 186: This page explores overwork as a source of distraction. A CEO, reflecting on how his ‘wild overwork’ led him to ‘sacrifice [relationships with] family’, reads a study finding the ‘average British worker… was only engaged in their work for less than three hours a day’. (So why is RTO a thing, again?) Though people were in the office, they were ‘mentally checked out’. This inspires him to propose an experiment at his own company: a four-day work week.
Page 189: The four-day week experiment at Perpetual Guardian was a success. ‘Time spent on social media at work… fell by 35 percent,’ and ‘Stress levels were down by 15 percent’. Crucially, the management ‘conceded that the company was achieving as much in four days as they had before in five.’ The change was made permanent, allowing employees time to ‘nurture relationships’ and have ‘”me time”‘. The text notes similar positive outcomes in other experiments, like Microsoft in Japan seeing a ’40 percent improvement in productivity’.
Page 199: Diet significantly impacts focus. Eating processed, low-nutrient food is ‘like putting rocket fuel into a mini: It would bust very quickly’. A first step to improve focus is to ‘stop feeding them fucking Coke for breakfast… and giving them proper food’. Modern food has seen a ‘profound degeneration’ toward processed items ‘stripped… of a lot of its nutritional value.”
Page 200: A Dutch study tested the effect of diet on children with focus issues. One group was assigned an ‘”eliminationist” diet’ (no synthetic additives or dyes). The results were stark: ‘more than 70 percent of the kids who cut out the preservatives and dyes improved their ability to pay attention, and the average improvement was a remarkable 50 percent’. A larger follow-up study confirmed the results. This supports the idea that ‘when you consume the foods that we evolved to eat, your brain will function better’.
Page 201: Our diets also harm focus because they contain chemicals that ‘act on our brains almost like drugs’. A 2007 study in Southampton found that kids given a drink with ‘common food additives and dyes’… ‘were significantly more likely to become hyperactive’. This evidence was ‘strong and decisive’, leading many European countries to ban the dyes, but ‘the U.S. regulators refused to’. This may contribute to the ‘gap in ADHD rates between Europe and the U.S.’ See also the Eat More Tomorrow mental model.
Page 204: Environmental pollution is presented as another major factor damaging attention. A French scientist, Barbara Demeneix, explains: ‘”At every stage of your life… forms of pollution will affect your attention span”‘.
Page 207: Lead poisoning is a significant historical and ongoing driver of attention problems. Research showed that lead ‘severely stunts your ability to pay attention’. A child exposed to lead is ‘two and a half times more likely to meet the criteria for ADHD’. Instead of addressing the source, authorities and industry blamed parents, telling them ‘you have failed to dust your homes’. This blame was often racialized, targeting ‘”uneducable Negro and Puerto Rican parents”‘.
Page 208: This page critiques the response to systemic problems like lead poisoning. The lead industry ‘bought the loyalty of some scientists, who systematically cast doubt on the evidence’. This is compared to our ‘extremely individualistic culture, where we are constantly pushed to see our problems as individual failings’. Hari advocates socialism; I advocate agency.
Page 213: Highlights the rapid proliferation of attention deficit hyperactivity disorder (ADHD) diagnoses, particularly in the English-speaking world. Between 2003 and 2011, US diagnoses “soared by 43 percent overall; and by 55 percent among girls,” reaching a point where 13% of US adolescents have the diagnosis. This spread the idea that “these children had a biological disorder” as the reason they weren’t paying attention, leading to a majority being prescribed powerful stimulant drugs.
Page 214: The author notes this chapter was the ‘hardest to write’ because ‘serious scientists disagree the most’ on this topic, including ‘whether ADHD actually exists in the way most people have been told it does, as a biological illness’.
Page 215: This page traces the rapid rise of the ADHD diagnosis. The concept of a ‘biological disorder’ for focus issues, absent from the 1952 psychiatric guide, was added in 1968 and has since ‘gained popularity’. This has soared to the point where ‘in many parts of the South in the United States, 30 percent of boys are now diagnosed with ADHD’. This has created a $10 billion stimulant market and a polarized debate between those who see it as a ‘biological disorder’ in the individual’s brain and those who argue ‘it is incorrect and harmful to see them as a biological disorder’. I think it fails basic logic to believe that such a diagnosis is correct. If 30% of all males have a mental disorder, then it can’t really be a mental disorder, can it? That’s well within the spectrum of normal human. (I note that Perplexity says broader statistics suggest 13-15% of boys in the US in general are diagnosed with ADHD, compared to about 7-8% of girls.)
Page 216: Describes the common experience of an ADHD diagnosis. A mother is told by a doctor that her son has a ‘problem with his brain’ and that genetics ‘account for “75 to 80 percent”‘ of the cause. While ‘distressing’, this diagnosis also offers relief: ‘Your son’s behavior isn’t your fault… you deserve sympathy’. The offered solution is Ritalin. Though the son ‘stopped being so restless and bouncing off the walls’, he also said – money quote – “one child I know told me that he felt like his brain was turned off when he took the drug.”
Page 218: An analogy is drawn between medicating humans and medicating animals. A vet, Nicholas Dodman, discovered he could stop a horse’s ‘compulsive behavior’ (cribbing) with an opioid-blocker, proving ‘you could dramatically change behavior by changing brain chemistry’. This led to a trend of medicating zoo animals, like giving a polar bear Prozac to stop it from ‘endlessly pacing’. Today, there are ‘parrots on Xanax… and cats on Prozac’, and these drugs are seen as a ‘management tool’ that ‘puts us a little more at ease’.
Page 219: The vet who pioneered medicating animals, Nicholas Dodman, admits “cribbing” in horses is ‘a condition of “domestication.” It doesn’t happen in the wild. The animals are suffering from ‘”frustrated biological objectives.”‘ He explains: ‘When they can’t express their innate nature, their behavior and focus go awry’. Dodman concedes that drugging the pacing polar bear ‘is a Band-Aid. The problem… is you’ve stuck it in a zoo.’nbsp; This, I think, is the correct mental model for ADHD: trait adaptivity, and not a “disease” to be treated.
Page 220: The author expresses concern that medicating animals for environmental stress is a way of “muffling their signals with drugs.” These behaviors are ‘a way of expressing distress’: the horse ‘hated being shut away’ and the dog ‘hated being left alone’. The author worries this encourages a ‘fantasy… that you could take a creature, ignore its nature, and make it live a life that fits the owner’s needs, not the animal’s, needs, without any cost’. (Ironically, Hari, of course, ignores human nature when it comes to incentives.)
Page 223: Dr. Sami Timimi provides examples of solving children’s attention problems by fixing their environment. One boy (Michael) was acting out because his father had disengaged. When he reconnected with his dad, ‘his attention problems gradually went away’. Another boy (Aden) was labeled hyperactive, but Sami visited the school and found ‘The classroom was in chaos’. When Aden was moved to a ‘new, less chaotic school’, his focus issues ‘faded’.
Page 224: Dr. Sami Timimi critiques the concept of an ADHD diagnosis, comparing the squishy ADHD diagnosis to a diagnosis of pneumonia with “an underlying pathogen or illness” where the medicine “can deal with the physical problem.”nbsp; He states: ‘ADHD is not a diagnosis. Its not a diagnosis. Its just a description of certain behaviors that sometimes occur together. That’s all it is.’ He compares it to diagnosing a cough by saying ‘”yes, the child has a cough”‘ without looking for the cause. He argues a label of attention problems should be the start of the process, not the end.
Page 225: A massive 40-year study tracking 200 people sought to find what factors ‘lead them to developing attention problems’. The lead scientist, Alan, initially ‘believed… that ADHD was caused entirely by some inborn biological problem’. However, he was ‘startled by what they found’. The ‘neurological status at birth didn’t help at all in predicting’ attention problems. Instead, ‘the surrounding context is the most important thing’, and a ‘crucial factor was “the amount of chaos in the environment.”‘
Page 228: This page highlights the chemical similarity between ADHD medication and street drugs. Dr. Nadine Ezard, who works with methamphetamine addicts, began a program to ‘legally give people addicted to meth… dextroamphetamine’, which is ‘the stimulant that is prescribed over a million times a day in the U.S. for kids with ADHD’. This treatment worked because the drug ‘scratched some of the same itch’, relieving the craving for meth.
Page 229: While stimulants and street meth ‘work in a similar way’, there are ‘important differences’ in dosage, delivery (pills vs. ‘smoking or injecting’) and purity. The text debunks the myth that stimulants affect “normal” and “ADHD” kids differently. Scientists found that ‘All children—indeed, all people—given Ritalin focus and pay attention better for a while’. This isn’t proof of an underlying disorder; it’s just the drug’s effect, which is why radar operators were given stimulants in WWII.
Page 230: There are several risks associated with giving stimulants to children. First, they ‘stunt the child’s growth’ by about ‘three centimeters’ over three years and increase the risk of heart problems. Second, and more worrying: ‘We simply don’t know the long-term effects.’ The animal research we have is ‘sobering’, showing that Ritalin given to adolescent rats causes ‘a crucial part of the brain that deals with experiencing rewards… shrinks significantly’.
Page 231: Studies show that stimulants ‘improve behavior on tasks that require repetition, but they do not improve learning’. One study found kids on stimulants improved 1.8% on tests, while those given guidance on behavior improved roughly as much. The ‘positive effects of stimulants don’t last’ because the body ‘develops a tolerance’. Dr. Charles Czeisler adds that stimulates reduce sleep, which has worrying implications for brain development.
Page 232: Contrasts the US view on ADHD with global skepticism. Many people in the US are persuaded “that this is a problem caused primarily by their child’s genetic makeup.” This biological explanation is supported by figures like Professor Hinshaw’s claim that “genes explain ’75 to 80 percent'” of the problem. This focus on a single biological cause (a potential multicausality error) is met with more skepticism elsewhere.
Page 233: This page challenges the high genetic estimates for ADHD, which are based on twin studies. These studies assume that identical and non-identical twins share the same environment, so any greater similarity between identical twins must be genetic. However, Dr. Jay Joseph points out a flaw: ‘identical twins do not actually experience the same environments as non-identical twins’. They ‘are treated more alike by parents, friends, and schools’ and are ‘psychologically closer’. This environmental similarity, not just genes, could explain their shared behaviors.
Page 239: Describes the dramatic change in childhood over the last few decades. The author contrasts the free, unsupervised play of his youth with the current reality. ‘By 2003, in the U.S. only 10 percent of children spent any time playing freely outdoors on a regular basis’. Childhood now occurs ‘overwhelmingly behind closed doors’ or is highly supervised. Schools have also changed, ‘forced to spend the majority of their time preparing and drilling children for tests’, while ‘Free play [has] fallen off a cliff’.
Page 240: Introduces Lenore Skenazy by contrasting her 1960s childhood with today. As a five-year-old, she walked to school alone, and by nine, she would “get on her bike and ride a few miles to the library” to read. She and her friends would play in the neighborhood without adult supervision. This is juxtaposed with the modern day, where such behavior can be reported as “parental negligence.” Back then, “Being a kid meant you went out” and played without supervision.
Page 241: This page introduces Lenore Skenazy and the shift in parenting. ‘By the time… [Lenore] had her own children… in the 1990s, everything had changed… Nobody let their kids out to play unsupervised, ever.’ Wanting her son to have a ‘small taste of freedom’, she let him ride the subway alone in New York. He returned ‘”levitating”‘ with confidence. When she wrote an article about this ‘commonsense thing’, she was ‘denounced… with horror and revulsion’. Revulsion is probably the right emotion for letting your kid ride the New York subway today; I think Hari downplays the very real nature of dangerous security risks in the modern world – we’re not in Mayberry anymore.
Page 243: This ‘gigantic shift’ in how children live is an ‘inversion of what every previous human society has thought’. The first negative impact is the loss of exercise. Scientific evidence shows ‘exercise provides an “exceptional boost” to attention in children’. Professor Joel Nigg explains that ‘for developing children, aerobic exercise expands the growth of brain connections… and the brain chemicals that support self-regulation’. He regards the evidence for this as ‘”definite”‘.
Pages 244 – 245: Even when children do play, it is now ‘mainly supervised by adults’. This ‘supervised play… has been drained of most of its value’. Children are ‘not getting that [chance to develop these skills]’ of negotiation and autonomy that prepare them for adulthood. Instead of exploring, kids are ‘effectively under house arrest’. This time is now filled with homework (which ‘exploded by 145 percent’) and screens.
Page 246: Connects the decline of childhood play to rising anxiety and poor focus. Professor Jonathan Haidt argues play deprivation is a key reason for the rise in anxiety among teens, as play teaches “skills that make it possible to cope with the unexpected.” Children deprived of play “will feel panicked and unable to cope a lot of the time.” This directly impacts focus, as there is “strong scientific evidence that if you are anxious, your attention will suffer.” This illustrates the link between stress and cognition.
Page 247: This change deprives children of developing intrinsic motivation. An ‘intrinsic motive’ means ‘doing it because you love it’, while an extrinsic motive means doing it ‘because you have been forced… to get something out of it’. It is ‘easier to focus… if your motives are intrinsic’. However, a child’s day ‘is filled, from seven in the morning to nine at night… with somebody else’s idea of what is important’, leaving no time to ‘figure out what [emotionally] turns you on’.
Page 249: Lenore Skenazy’s “Let Grow Play Day” experiment revealed that children have lost the ability to play freely. When teachers filled classrooms with boxes and toys and told kids to ‘Go play’, a ‘large number of the children just stood there’. One even ‘lay down in a corner and went to sleep’. A teacher realized, ‘They don’t know how to play… They just did not know how to do it.’ Their lives had been ‘constantly managed for them by adults’.
Page 252: Free play allows children to develop “mastery.” A boy, L.B., who struggled with reading (an extrinsic task) was ‘given the chance… to develop an intrinsic motivation’ (building boats). He ‘flourished’, and his reading ‘hugely improved’ because he was now reading about his passion. This connects to the human psychological need for ‘mastery”—that we are good at something.’ When you feel mastery, ‘you will find it much easier to focus’, whereas the school system ‘makes a lot of kids… feel incompetent’. Hari notes – “if you feel incompetent, your attention will shrivel like a salted snail.” Hari goes on to note “I realized that we hae a school system right now that is so narrow that it makes a lot of kids (especially boys, I think) feel that they aren’t good at anything. Their experience of school is constantly being made to feel incompetent.” Hari doesn’t mention this, but in my view, back to the ADHD diagnoses – little boys are simply not meant to sit still in a classroom. That’s not how they were made.
Page 253: The lack of autonomy is linked to rising anxiety. One mother refused to let her thirteen-year-old do laundry, telling her ‘”Absolutely not. You’re not doing the laundry. You may ruin it.”‘ The teacher concluded: ‘[The kids] get no confidence, because the small things build confidence.’ One fourteen-year-old boy was even ‘too frightened to walk into town’ alone.
Page 255: Questions whether the structure of modern schooling is “hindering our kids” from developing focus. The author recounts his own experience of being forced to follow a rigid, arbitrary timetable, where the only incentive given for learning was “‘Because I say so'” or “‘Because you’ll have a test on it.'” He contrasts this with his ability to read for hours on end at home when choosing his own material, suggesting the school structure itself undermined his focus. He concludes with a quote that I’ve often thought and said myself: “I always loved learning, and I always hated school.” See also our review of Rob Henderson’s Troubled – he often read himself out of school but put very little effort into school.
Page 279: Hari comes pretty close to arguing for degrowth – again, irritating that all the brilliance is mixed with socialism.
