they're facing the direction of next morning's sunrise, behavior that requires the plant to anticipate the future. What's more, young shoots of corn can “remember” the directions of light sources.

Sleep is tied to many positive health outcomes according to a constant stream of medical research, much of which recommends more than seven hours a night. My goal was to sleep eight hours each night, and for the first two weeks of the month I tried and failed. I didn't manage it once. It started stressing me out.Wake up, people: You're fooling yourself about sleep, study says I did get more sleep than I would have otherwise because I prioritized getting to bed earlier. But between work, training for a marathon, kids' bedtimes and evening plans, my life was not conducive to that schedule. But since I'm making up the rules (and you make up yours) I gave up on sleep.

Research ties nature exposure to both longevity and happiness, so I made it a goal to commune with nature every day. This could include a run through a park, stopping to hug a tree (which I did at least once), or watching a convoy of ants cross a sidewalk.

Another super-habit for mental and physical health, I made an effort to incorporate meditation in some form -- whether it was 10 breaths, 30 minutes, guided, formal, mantra-led, what have you -- every day.

To complement March's switch-up, my plan for June was the same split: 8 hours of sleep at night and active listening with the kids. I didn't think I could pull a straight fortnight of great sleep, so my aim was for 15 nights of sleep and 15 days of not doing something else while listening.

At CNN, I sit near a constant pile of sweets. And that combined with my weakness for them equals a snacking problem. So in July, my goal was to make fresh fruit my standard snack of choice and eat at least one piece or serving a day. And more water -- at least a pint before coffee in the morning.

In August I attempted to not stay seated for more than 30 minutes during waking hours. Recent research has associated a number of poor health conditions with a sedentary lifestyle. And while no one can definitively say how much sitting is bad for us, moving every 30 minutes has emerged as a good guideline.

My commitment in September was 15 minutes of some form of creative writing each day, almost entirely in a writer's notebook that I've had since college. It's full of random dialogue, lists and story plots, and I used to write in it often but not so much in recent years.

Read a novel. That was it. Given that I mainly read non-fiction, this idea seemed rather novel (sorry).

My intention was to make a daily gesture of gratitude -- an emotional state with its own positive health outcomes -- and I quickly fell behind. I decided instead (because, again, I make up the rules) to make the goal a total of 30 thank yous, one for each day of the month, and I managed to cram them all in.

In another attempt to combat unhealthy snacking, my final goal for 2019 was to convert my diet into one filled with non-processed, whole foods. Carrots and peanut butter instead of donuts; almonds instead of old Halloween candy -- you get the idea. I also declared my intention to track my progress and give myself a daily score.

There is much to be said, however, for art’s ability to evoke emotion based on common experience, sincerity, talent, and unique skill. Rich proves that AI can be used to answer complicated questions. But what we think of as creative work in the humanities is much more often about asking questions than it is about answering them.

Monday’s letter argues that “open-mindedness, critical thinking, and debate” are “our best antidotes to bigotry;” that a bigot is a person “who is obstinately or intolerantly devoted to his or her own opinions and prejudices;” and that the only people who need fear open-minded inquiry and robust debate “are the actual bigots,

In 2014, the Pew Research Center asked Americans to rank the “greatest dangers in the world.” A plurality put inequality first, ahead of “religious and ethnic hatred,” nuclear weapons, and environmental degradation. And yet people don’t agree about what, exactly, “equality” means.

One side argues that the city should guarantee procedural equality: it should insure that all students and families are equally informed about and encouraged to study for the entrance exam. The other side argues for a more direct, representation-based form of equality: it would jettison the exam, adopting a new admissions system designed to produce student bodies reflective of the city’s demography

In the past year, for example, New York City residents have found themselves in a debate over the city’s élite public high schools

The complexities of egalitarianism are especially frustrating because inequalities are so easy to grasp. C.E.O.s, on average, make almost three hundred times what their employees make; billionaire donors shape our politics; automation favors owners over workers; urban economies grow while rural areas stagnate; the best health care goes to the richest.

It’s not just about money. Tocqueville, writing in 1835, noted that our “ordinary practices of life” were egalitarian, too: we behaved as if there weren’t many differences among us. Today, there are “premiere” lines for popcorn at the movies and five tiers of Uber;

Inequality is everywhere, and unignorable. We’ve diagnosed the disease. Why can’t we agree on a cure?

In a book based on those lectures, “One Another’s Equals: The Basis of Human Equality,” Waldron points out that people are also marked by differences of skill, experience, creativity, and virtue. Given such consequential differences, he asks, in what sense are people “equal”?

According to the Declaration of Independence, it is “self-evident” that all men are created equal. But, from a certain perspective, it’s our inequality that’s self-evident.

More than twenty per cent of Americans, according to a 2015 poll, agree: they believe that the statement “All men are created equal” is false.

In Waldron’s view, though, it’s not a binary choice; it’s possible to see people as equal and unequal simultaneously. A society can sort its members into various categories—lawful and criminal, brilliant and not—while also allowing some principle of basic equality to circumscribe its judgments and, in some contexts, override them

Egalitarians like Dworkin and Waldron call this principle “deep equality.” It’s because of deep equality that even those people who acquire additional, justified worth through their actions—heroes, senators, pop stars—can still be considered fundamentally no better than anyone else.

In the course of his search, he explores centuries of intellectual history. Many thinkers, from Cicero to Locke, have argued that our ability to reason is what makes us equals.

Other thinkers, including Immanuel Kant, have cited our moral sense.

Some philosophers, such as Jeremy Bentham, have suggested that it’s our capacity to suffer that equalizes us

Waldron finds none of these arguments totally persuasive.

In various religious traditions, he observes, equality flows not just from broad assurances that we are all made in God’s image but from some sense that everyone is the protagonist in a saga of error, realization, and redemption: we’re equal because God cares about how things turn out for each of us.

Waldron himself is taken by Hannah Arendt’s related concept of “natality,” the notion that what each of us share is having been born as a “newcomer,” entering into history with “the capacity of beginning something anew, that is, of acting.”

equality may be not a self-evident fact about human beings but a human-made social construction that we must choose to put into practice.

In the end, Waldron concludes that there is no “small polished unitary soul-like substance” that makes us equal; there’s only a patchwork of arguments for our deep equality, collectively compelling but individually limited.

Equality is a composite idea—a nexus of complementary and competing intuitions.

The blurry nature of equality makes it hard to solve egalitarian dilemmas from first principles. In each situation, we must feel our way forward, reconciling our conflicting intuitions about what “equal” means.

The communities that have the easiest time doing that tend to have some clearly defined, shared purpose. Sprinters competing in a hundred-metre dash have varied endowments and train in different conditions; from a certain perspective, those differences make every race unfair.

By embracing an agreed-upon theory of equality before the race, the sprinters can find collective meaning in the ranked inequalities that emerge when it ends

Perhaps because necessity is so demanding, our egalitarian commitments tend to rest on a different principle: luck.

“Some people are blessed with good luck, some are cursed with bad luck, and it is the responsibility of society—all of us regarded collectively—to alter the distribution of goods and evils that arises from the jumble of lotteries that constitutes human life as we know it.” Anderson, in an influential coinage, calls this outlook “luck egalitarianism.”

This sort of artisanal egalitarianism is comparatively easy to arrange. Mass-producing it is what’s hard. A whole society can’t get together in a room to hash things out. Instead, consensus must coalesce slowly around broad egalitarian principles.

No principle is perfect; each contains hidden dangers that emerge with time. Many people, in contemplating the division of goods, invoke the principle of necessity: the idea that our first priority should be the equal fulfillment of fundamental needs. The hidden danger here becomes apparent once we go past a certain point of subsistence.

a core problem that bedevils egalitarianism—what philosophers call “the problem of expensive tastes.”

The problem—what feels like a necessity to one person seems like a luxury to another—is familiar to anyone who’s argued with a foodie spouse or roommate about the grocery bil

The problem is so insistent that a whole body of political philosophy—“prioritarianism”—is devoted to the challenge of sorting people with needs from people with wants

the line shifts as the years pass. Medical procedures that seem optional today become necessities tomorrow; educational attainments that were once unusual, such as college degrees, become increasingly indispensable with time

Some thinkers try to tame the problem of expensive tastes by asking what a “normal” or “typical” person might find necessary. But it’s easy to define “typical” too narrowly, letting unfair assumptions influence our judgment

an odd feature of our social contract: if you’re fired from your job, unemployment benefits help keep you afloat, while if you stop working to have a child you must deal with the loss of income yourself. This contradiction, she writes, reveals an assumption that “the desire to procreate is just another expensive taste”; it reflects, she argues, the sexist presumption that “atomistic egoism and self-sufficiency” are the human norm. The word “necessity” suggests the idea of a bare minimum. In fact, it sets a high bar. Clearing it may require rethinking how society functions.

And leaders are never just leaders, they are always leaders of a particular social group – a nation, a political party, a religion

leadership is a group process: and, more specifically, it is the cultivation of a “we” relationship between leaders and followers.

Effective leadership, then, is not about what separates the leader from others. It is about what brings the leader together with group members and allows him or her to represent them

n effective leader is one who is seen to be one of us, to work for us and to achieve the things we value. That isn’t about being ordinary or typical. It is about being prototypical – of representing the values and the qualities that make our group distinctive.

In addition, effective leaders are not passive. They actively craft the group narrative and their own personal narrative to make the two mesh: they are skilled entrepreneurs of identity.

Hence, no given set of qualities will guarantee effective leadership, for these will change according to the identity of the group.

the performative politics of populism can backfire by making one unrepresentative as the groupings change. In the midst of a pandemic where the widest possible compliance to restrictive measures is necessary, the nation and its communities must be unified and inclusive. The inherently divisive categories of populism are no longer tenable.

Moreover, we need competent governance to get us through, rather than insurgent incompetence to get our votes. In this global crisis, our blundering prime minister is no longer of the group, nor for the group, and certainly not achieving what the group needs.

Adams did not just stick to comics: he is the author of over a dozen books (not counting the comic compendiums), which advise and analyze not only on surviving the office but also on daily life, future technology trends, romance, self-help strategy, and more. 

In his earlier books, you can feel the weight of the 1990s pressing down on his work, flattening and numbing its potency; this was the period that social scientist Francis Fukuyama dubbed “the end of history”, when the Cold War had ended, the West had won, 9/11 was just two numbers, and there were no grand missions left, no worlds left to conquer. While for millions of people, both in the United States and abroad, life was still chaotic and miserable, a lot of people found themselves living lives that were under no great immediate threat: without bombs or fascism or the threat of eviction to worry about, there was nothing left to do but to go to the office and enjoy fast-casual dining and Big Gulps, just as the Founding Fathers envisioned.

This dull but steady life produced a sense of slow-burn anxiety prominent in much of the pop culture of the time, as can be seen in movies such as Office Space, Fight Club and The Matrix, movies which cooed to their audience: there’s got to be more to life than this, right?

Beware: as I’m pretty sure Nietzsche said, when you gaze into Dilbert, eventually Dilbert gazes back into you.

for someone who satirizes business bullshit, Adams is a person who seems to have bought into much of it wholeheartedly; when he explains his approach to life he tends to speak in LinkedIn truisms, expounding on his “skill stacks” and “maximizing [his] personal energy”. (You can read more about this in his career advice book, How to Fail at Almost Everything and Still Win Big;

Following his non-Dilbert career more carefully, you can see that at every stage of his career, he’s actually quite heavily invested in the bullshit he makes fun of every day, or at least some aspects of it: he possesses an MBA from UC Berkeley, and has launched or otherwise been involved in a significant number of business ventures, most amusingly a health food wrap called the “Dilberito”.

In the past few years, Adams has gained some notoriety as a Trump supporter; having slowly moved from “vaguely all-over-the-place centrist who has some odd thoughts and thinks some aspects of Trump are impressive” to full-on MAGA guy, even writing a book called Win Bigly praising Trump’s abilities as a “master persuader”.

this is a guy who hates drab corporatespeak but loves the ideology behind it, a guy who describes the vast powerlessness of life but believes you can change it by writing some words on a napkin. That blend of rebellion against the symptoms of post-Cold War society and sworn allegiance to its machinations couldn’t lead anywhere else but to Trump, a man who rails against ‘elites’ while allowing them to run the country into the ground.

In Dilbert the Pointy-haired Boss uses this type of thinking to evil ends, in the tradition of Catch-22 and other satires of systemic brutality, but the relatable characters use it to their advantage too—by using intellectual sleight of hand with the boss to justify doing less work, or by finding clever ways to look busy when they’re not, or to avoid people who are unpleasant to be around.

I just think Adams is a guy who spent so long in the world of slick aphorisms and comic-strip logic that it eventually ate into his brain, became his entire manner of thinking

Einstein, Mozart, Michelangelo, Steve Jobs, Bill Gates – all these overachievers are widely believed to be, or have been, on the spectrum.

I used recreational drugs to smooth me through the challenges of social communication.

With every interaction, verbal or written, I go through a mental checklist: is my response appropriate? Is it relevant? Is this something only I am going to find interesting? Is my tone right? Trying to follow social rules and adapt to an allistic [non-autistic] world is exhausting. No one sees what is going on inside my head.

Misunderstandings in communication can blow up quite quickly.

I burnt out in my late 20s.

My greatest fear has been something I’ve always referred to as “the big alone”. Even when I’ve been in loving relationships, as I am now, there has been a terrible aloneness in not understanding why I am not like other people.

I was able to look back at situations and misunderstandings and understand what had happened. I’d been told my communication could be “off” sometimes – a bit intense, a bit abrupt.

Autistic children spend a lot of time “masking”, imitating so-called “normal” behaviour. They need to be able to experience their authentic selves.

Over the past five or 10 years, the concept of neurodiversity – the idea that these differences in our brains should be celebrated – has become better known. We deserve equality, respect and full social inclusion.

We need to start making space for neurodivergent people at school, at work, in life generally. Autistic people bring a whole new set of skills with them.

Imagination is the capacity to make associations among all these bits of information and to synthesize them into patterns and concepts.

When you walk, say, into a coffee shop you don’t see an array of surfaces, lights and angles. Your imagination instantly coalesces all that into an image: “coffee shop.”

Neuroscientists have come to appreciate how fantastically complicated and subjective this process of creating mental images really is. You may think perception is a simple “objective” process of taking in the world and cognition is a complicated process of thinking about it. But that’s wrong.

Perception — the fast process of selecting, putting together, interpreting and experiencing facts, thoughts and emotions — is the essential poetic act that makes you you.

For example, you don’t see the naked concept “coffee shop.” The image you create is coated with personal feelings, memories and evaluations. You see: “slightly upscale suburban coffee shop trying and failing to send off a hipster vibe.” The imagination, Charles Darwin wrote, “unites former images and ideas, independently of the will, and thus creates brilliant and novel results.”

Imagination helps you perceive reality, try on other realities, predict possible futures, experience other viewpoints. And yet how much do schools prioritize the cultivation of this essential ability?

“A fool sees not the same tree that a wise man sees,” William Blake observed.

Can you improve your imagination? Yes. By creating complex and varied lenses through which to see the world

A person who feeds his or her imagination with a fuller repertoire of thoughts and experiences has the ability not only to see reality more richly but also — even more rare — to imagine the world through the imaginations of others.

This is the skill we see in Shakespeare to such a miraculous degree — his ability to disappear into his characters and inhabit their points of view without ever pretending to explain them.

Different people have different kinds of imagination. Some people mainly focus on the parts of the world that can be quantified.

it often doesn’t see the subjective way people coat the world with values and emotions and aspirations, which is exactly what we want to see if we want to glimpse how they experience their experience.

Furthermore, imagination can get richer over time. When you go to Thanksgiving dinner, your image of Uncle Frank contains the memories of past Thanksgivings, the arguments and the jokes, and the whole sum of your common experiences. The guy you once saw as an insufferable blowhard you now see — as your range of associations has widened and deepened — as a decent soul struggling with his wounds.

What happens to a society that lets so much of its imaginative capacity lie fallow? Perhaps you wind up in a society in which people are strangers to one another and themselves.

You might be well-intentioned, rational, and mistaken, simply because so much in our thinking can go wrong. (“RATIONAL, adj.: Devoid of all delusions save those of observation, experience and reflection,”

You might be rational and self-deceptive, because telling yourself that you are rational can itself become a source of bias. It’s possible that you are trying to appear rational only because you want to impress people; or that you are more rational about some things (your job) than others (your kids); or that your rationality gives way to rancor as soon as your ideas are challenged. Perhaps you irrationally insist on answering difficult questions yourself when you’d be better off trusting the expert consensus.

Not just individuals but societies can fall prey to false or compromised rationality. In a 2014 book, “The Revolt of the Public and the Crisis of Authority in the New Millennium,” Martin Gurri, a C.I.A. analyst turned libertarian social thinker, argued that the unmasking of allegedly pseudo-rational institutions had become the central drama of our age: people around the world, having concluded that the bigwigs in our colleges, newsrooms, and legislatures were better at appearing rational than at being so, had embraced a nihilist populism that sees all forms of public rationality as suspect.

modern life would be impossible without those rational systems; we must improve them, not reject them. We have no choice but to wrestle with rationality—an ideal that, the sociologist Max Weber wrote, “contains within itself a world of contradictions.”

Where others might be completely convinced that G.M.O.s are bad, or that Jack is trustworthy, or that the enemy is Eurasia, a Bayesian assigns probabilities to these propositions. She doesn’t build an immovable world view; instead, by continually updating her probabilities, she inches closer to a more useful account of reality. The cooking is never done.

Rationality is one of humanity’s superpowers. How do we keep from misusing it?

Start with the big picture, fixing it firmly in your mind. Be cautious as you integrate new information, and don’t jump to conclusions. Notice when new data points do and do not alter your baseline assumptions (most of the time, they won’t alter them), but keep track of how often those assumptions seem contradicted by what’s new. Beware the power of alarming news, and proceed by putting it in a broader, real-world context.

Bayesian reasoning implies a few “best practices.”

Keep the cooked information over here and the raw information over there; remember that raw ingredients often reduce over heat

We want to live in a more rational society, but not in a falsely rationalized one. We want to be more rational as individuals, but not to overdo it. We need to know when to think and when to stop thinking, when to doubt and when to trust.

But the real power of the Bayesian approach isn’t procedural; it’s that it replaces the facts in our minds with probabilities.

Applied to specific problems—Should you invest in Tesla? How bad is the Delta variant?—the techniques promoted by rationality writers are clarifying and powerful.

the rationality movement is also a social movement; rationalists today form what is sometimes called the “rationality community,” and, as evangelists, they hope to increase its size.

In “Rationality,” “The Scout Mindset,” and other similar books, irrationality is often presented as a form of misbehavior, which might be rectified through education or socialization.

Greg tells me that, in his business, it’s not enough to have rational thoughts. Someone who’s used to pondering questions at leisure might struggle to learn and reason when the clock is ticking; someone who is good at reaching rational conclusions might not be willing to sign on the dotted line when the time comes. Greg’s hedge-fund colleagues describe as “commercial”—a compliment—someone who is not only rational but timely and decisive.

You can know what’s right but still struggle to do it.

Following through on your own conclusions is one challenge. But a rationalist must also be “metarational,” willing to hand over the thinking keys when someone else is better informed or better trained. This, too, is harder than it sounds.

For all this to happen, rationality is necessary, but not sufficient. Thinking straight is just part of the work. 

I found it possible to be metarational with my dad not just because I respected his mind but because I knew that he was a good and cautious person who had my and my mother’s best interests at heart.

between the two of us, we had the right ingredients—mutual trust, mutual concern, and a shared commitment to reason and to act.

Intellectually, we understand that our complex society requires the division of both practical and cognitive labor. We accept that our knowledge maps are limited not just by our smarts but by our time and interests. Still, like Gurri’s populists, rationalists may stage their own contrarian revolts, repeatedly finding that no one’s opinions but their own are defensible. In letting go, as in following through, one’s whole personality gets involved.

in truth, it maps out a series of escalating challenges. In search of facts, we must make do with probabilities. Unable to know it all for ourselves, we must rely on others who care enough to know. We must act while we are still uncertain, and we must act in time—sometimes individually, but often together.

The realities of rationality are humbling. Know things; want things; use what you know to get what you want. It sounds like a simple formula.

The real challenge isn’t being right but knowing how wrong you might be.By Joshua RothmanAugust 16, 2021

Writing about rationality in the early twentieth century, Weber saw himself as coming to grips with a titanic force—an ascendant outlook that was rewriting our values. He talked about rationality in many different ways. We can practice the instrumental rationality of means and ends (how do I get what I want?) and the value rationality of purposes and goals (do I have good reasons for wanting what I want?). We can pursue the rationality of affect (am I cool, calm, and collected?) or develop the rationality of habit (do I live an ordered, or “rationalized,” life?).

Weber worried that it was turning each individual into a “cog in the machine,” and life into an “iron cage.” Today, rationality and the words around it are still shadowed with Weberian pessimism and cursed with double meanings. You’re rationalizing the org chart: are you bringing order to chaos, or justifying the illogical?

For Aristotle, rationality was what separated human beings from animals. For the authors of “The Rationality Quotient,” it’s a mental faculty, parallel to but distinct from intelligence, which involves a person’s ability to juggle many scenarios in her head at once, without letting any one monopolize her attention or bias her against the rest.

In “The Rationality Quotient: Toward a Test of Rational Thinking” (M.I.T.), from 2016, the psychologists Keith E. Stanovich, Richard F. West, and Maggie E. Toplak call rationality “a torturous and tortured term,” in part because philosophers, sociologists, psychologists, and economists have all defined it differently

Galef, who hosts a podcast called “Rationally Speaking” and co-founded the nonprofit Center for Applied Rationality, in Berkeley, barely uses the word “rationality” in her book on the subject. Instead, she describes a “scout mindset,” which can help you “to recognize when you are wrong, to seek out your blind spots, to test your assumptions and change course.” (The “soldier mindset,” by contrast, encourages you to defend your positions at any cost.)

Galef tends to see rationality as a method for acquiring more accurate views.

Pinker, a cognitive and evolutionary psychologist, sees it instrumentally, as “the ability to use knowledge to attain goals.” By this definition, to be a rational person you have to know things, you have to want things, and you have to use what you know to get what you want.

Introspection is key to rationality. A rational person must practice what the neuroscientist Stephen Fleming, in “Know Thyself: The Science of Self-Awareness” (Basic Books), calls “metacognition,” or “the ability to think about our own thinking”—“a fragile, beautiful, and frankly bizarre feature of the human mind.”

A successful student uses metacognition to know when he needs to study more and when he’s studied enough: essentially, parts of his brain are monitoring other parts.

In everyday life, the biggest obstacle to metacognition is what psychologists call the “illusion of fluency.” As we perform increasingly familiar tasks, we monitor our performance less rigorously; this happens when we drive, or fold laundry, and also when we think thoughts we’ve thought many times before

The trick is to break the illusion of fluency, and to encourage an “awareness of ignorance.”

metacognition is a skill. Some people are better at it than others. Galef believes that, by “calibrating” our metacognitive minds, we can improve our performance and so become more rational

There are many calibration methods

nowing about what you know is Rationality 101. The advanced coursework has to do with changes in your knowledge.

Most of us stay informed straightforwardly—by taking in new information. Rationalists do the same, but self-consciously, with an eye to deliberately redrawing their mental maps.

The challenge is that news about distant territories drifts in from many sources; fresh facts and opinions aren’t uniformly significant. In recent decades, rationalists confronting this problem have rallied behind the work of Thomas Bayes

So-called Bayesian reasoning—a particular thinking technique, with its own distinctive jargon—has become de rigueur.

the basic idea is simple. When new information comes in, you don’t want it to replace old information wholesale. Instead, you want it to modify what you already know to an appropriate degree. The degree of modification depends both on your confidence in your preëxisting knowledge and on the value of the new data. Bayesian reasoners begin with what they call the “prior” probability of something being true, and then find out if they need to adjust it.

Bayesian reasoning is an approach to statistics, but you can use it to interpret all sorts of new information.

“It is hard to look at increasing trends in media consumption of all types, media multitasking and rates of ADHD in young people and not conclude that there is a decrease in their attention span,

Emerging research suggests that watching short, fast-paced videos makes it harder for kids to sustain activities that don’t offer instant—and constant—gratification.

One of the few studies specifically examining TikTok-related effects on the brain focused on Douyin, the TikTok equivalent in China, made by the same Chinese parent company, ByteDance Ltd. It found that the personalized videos the app’s recommendation engine shows users activate the reward centers of the brain, as compared with the general-interest videos shown to new users.

Brain scans of Chinese college students showed that areas involved in addiction were highly activated in those who watched personalized videos.

It also found some people have trouble controlling when to stop watching.

attention. “If kids’ brains become accustomed to constant changes, the brain finds it difficult to adapt to a nondigital activity where things don’t move quite as fast,”

A TikTok spokeswoman said the company wants younger teens to develop positive digital habits early on, and that it recently made some changes aimed at curbing extensive app usage. For example, TikTok won’t allow users ages 13 to 15 to receive push notifications after 9 p.m. TikTok also periodically reminds users to take a break to go outside or grab a snack.

Kids have a hard time pulling away from videos on YouTube, too, and Google has made several changes to help limit its use, including turning off autoplay by default on accounts of people under 18.

When kids do things that require prolonged focus, such as reading or solving math problems, they’re using directed attention

This function starts in the prefrontal cortex, the part of the brain responsible for decision making and impulse control.

“Directed attention is the ability to inhibit distractions and sustain attention and to shift attention appropriately. It requires higher-order skills like planning and prioritizing,”

Kids generally have a harder time doing this—and putting down their videogame controllers—because the prefrontal cortex isn’t fully developed until age 25.

“We speculate that individuals with lower self-control ability have more difficulty shifting attention away from favorite video stimulation,

“In the short-form snackable world, you’re getting quick hit after quick hit, and as soon as it’s over, you have to make a choice,” said Mass General’s Dr. Marci, who wrote the new book “Rewired: Protecting Your Brain in the Digital Age.” The more developed the prefrontal cortex, the better the choices.

Dopamine is a neurotransmitter that gets released in the brain when it’s expecting a reward. A flood of dopamine reinforces cravings for something enjoyable, whether it’s a tasty meal, a drug or a funny TikTok video.

“TikTok is a dopamine machine,” said John Hutton, a pediatrician and director of the Reading & Literacy Discovery Center at Cincinnati Children’s Hospital. “If you want kids to pay attention, they need to practice paying attention.”

Researchers are just beginning to conduct long-term studies on digital media’s effects on kids’ brains. The National Institutes of Health is funding a study of nearly 12,000 adolescents as they grow into adulthood to examine the impact that many childhood experiences—from social media to smoking—have on cognitive development.

she predicts they will find that when brains repeatedly process rapid, rewarding content, their ability to process less-rapid, less-rewarding things “may change or be harmed.”

“It’s like we’ve made kids live in a candy store and then we tell them to ignore all that candy and eat a plate of vegetables,”

“We have an endless flow of immediate pleasures that’s unprecedented in human history.”

Parents and kids can take steps to boost attention, but it takes effort

Swap screen time for real time. Exercise and free play are among the best ways to build attention during childhood,

“Depriving kids of tech doesn’t work, but simultaneously reducing it and building up other things, like playing outside, does,”

Practice restraint.

“When you practice stopping, it strengthens those connections in the brain to allow you to stop again next time.”

Use tech’s own tools. TikTok has a screen-time management setting that allows users to cap their app usage.

Ensure good sleep. Teens are suffering from a sleep deficit.

when Mr. Nichol tweaked his requests a little, adding or subtracting a few words here or there, it provided what he wanted. When he asked for “a piano in a living room filled with sand,” the image looked more like a beach in a living room.

DALL-E is what artificial intelligence researchers call a neural network, which is a mathematical system loosely modeled on the network of neurons in the brain.

the same technology that recognizes the commands spoken into smartphones and identifies the presence of pedestrians as self-driving cars navigate city streets.

A neural network learns skills by analyzing large amounts of data. By pinpointing patterns in thousands of avocado photos, for example, it can learn to recognize an avocado.

DALL-E looks for patterns as it analyzes millions of digital images as well as text captions that describe what each image depicts. In this way, it learns to recognize the links between the images and the words.

Many big companies are what one would describe as multi-business firms, an organizational form where you have a corporate parent and subsidiary units," said co-author Abhinav Gupta

"Narcissism affects people's desire to be distinctive," Gupta said. "It's correlated by people wanting glory for themselves. We hypothesized that business-unit heads that have those traits would be the ones to say, 'We don't want to work with you. We have sufficient skills and knowledge and abilities that we will work independently.' That was very strongly borne out based on our research design."

The study found that unit-head narcissism can prevent knowledge sharing. That tendency diminished in fast-changing or complex environments because narcissists had an excuse to pursue external ideas. But when businesses have high inter-unit competition, narcissists are more tempted to distinguish themselves from other units.

"This research kind of goes against the grain of that. If you create the perception of competition inside an organization, then that will have some downstream effects. You will be essentially foregoing some essential knowledge-sharing activities."

Forensic science, which drives the plots of movies and television shows, is accorded great respect by the public. And in the proper hands, it can provide persuasive insight. But in the wrong hands, it can trap innocent people in a vise of seeming inerrancy—and it has done so far too often. What’s more, although some forensic disciplines, such as DNA analysis, are reliable, others have been shown to have serious limitations.

Yezzo is not like Annie Dookhan, a chemist in a Massachusetts crime laboratory who boosted her productivity by falsifying reports and by “dry labbing”—that is, reporting results without actually conducting any tests.

Nor is Yezzo like Michael West, a forensic odontologist who claimed that he could identify bite marks on a victim and then match those marks to a specific person.

The deeper issue with forensic science lies not in malfeasance or corruption—or utter incompetence—but in the gray area where Yezzo can be found. Her alleged personal problems are unusual: Only because of them did the details of her long career come to light.

to the point of alignment; how rarely an analyst’s skills are called into question in court; and how seldom the performance of crime labs is subjected to any true oversight.

More than half of those exonerated by post-conviction DNA testing had been wrongly convicted based on flawed forensic evidence.

The quality of the work done in crime labs is almost never audited.

Even the best forensic scientists can fall prey to unintentional bias.

Study after study has demonstrated the power of cognitive bias.

Cognitive bias can of course affect anyone, in any circumstance—but it is particularly dangerous in a criminal-justice system where forensic scientists have wide latitude as well as some incentive to support the views of prosecutors and the police.

For this crew, the early success of their past companies or careers is usually prologue, and their skills will, of course, transfer to any area they choose to conquer (including magically solving free speech). But what they are actually doing is winging it.

There is a tendency, especially when it comes to the über-rich and powerful, to assume and to fantasize about what we can’t see. We ascribe shadowy brilliance or malevolence, which may very well be unearned or misguided.

What’s striking about the Musk messages, then, is the similarity between these men’s behavior behind closed doors and in public on Twitter. Perhaps the real revelation here is that the shallowness you see is the shallowness you get.

Psychological avoidance is akin to an ostrich burying its head in the sand, choosing ignorance over confrontation, all while a storm brews in the background.

depression and anxiety disorders cost the global economy $1 trillion each year in lost productivity.

avoidance, a strategy that not only fails to solve problems but fuels them.

Psychological avoidance isn’t about the actions we take or don’t take, but the intentions behind them. If our actions aim to squash discomfort hastily, then we’re probably 2favoiding

the three ways people tend to practice psychological avoidance.

Reacting

It’s when we reply hastily to an email that upsets us or raise our voices without considering the consequences.

Reacting is any response that seeks to eliminate the source of discomfort

Retreating

Retreating is the act of moving away or pulling back from anxiety-inducing situations

For example, my client with the fear of public speaking took a different job to avoid it. Others may reach for a glass of wine to numb out o

Remaining

Remaining is sticking to the status quo to avoid the discomfort of change.

Psychological avoidance is a powerful enemy, but there are three science-based skills to fight it.

Shifting involves checking in with your thoughts, especially when anxiety comes knocking. In those moments, we often have black-and-white, distorted thoughts, just like my client, who was worried about being in a romantic relationship, telling himself, “I will never be in a good relationship.”

Shifting is taking off dark, monochrome glasses and seeing the world in color again. Challenge your thoughts, clean out your lenses, by asking yourself, “Would I say this to my best friend in this scenario?

Approaching

taking a step that feels manageable.

The opposite of avoiding is approaching

Ask yourself: What is one small step I can take toward my fears and anxiety to overcome my avoidance.

Aligning

Aligning is living a values-driven life, where our daily actions are aligned with what matters the most to us: our values.

This is the opposite of what most of us do while anxious. In moments of intense anxiety, we tend to let our emotions, not our values, dictate our actions. To live a values-driven life, we need to first identify our values, whether that is health, family, work or something else. Then we need to dedicate time and effort to our values.

If you didn’t study Jane Austen while you were here, you probably lack the capacity to think clearly about making a marriage decision. If you didn’t read George Eliot, then you missed a master class on how to judge people’s character. If you didn’t read Nietzsche, you are probably unprepared to handle the complexities of atheism—and if you didn’t read Augustine and Kierkegaard, you’re probably unprepared to handle the complexities of faith.

The list goes on. If you didn’t read de Tocqueville, you probably don’t understand your own country. If you didn’t study Gibbon, you probably lack the vocabulary to describe the rise and fall of cultures and nations.

The wisdom of the ages is your inheritance; it can make your life easier. These resources often fail to get shared because universities are too careerist, or because faculty members are more interested in their academic specialties or politics than in teaching undergraduates, or because of a host of other reasons

What are you putting into your mind? Our culture spends a lot less time worrying about this, and when it does, it goes about it all wrong.

my worry is that, especially now that you’re out of college, you won’t put enough really excellent stuff into your brain.

I worry that it’s possible to grow up now not even aware that those upper registers of human feeling and thought exist.

The theory of maximum taste says that each person’s mind is defined by its upper limit—the best that it habitually consumes and is capable of consuming.

After college, most of us resolve to keep doing this kind of thing, but we’re busy and our brains are tired at the end of the day. Months and years go by. We get caught up in stuff, settle for consuming Twitter and, frankly, journalism. Our maximum taste shrinks.

I’m worried about the future of your maximum taste. People in my and earlier generations, at least those lucky enough to get a college education, got some exposure to the classics, which lit a fire that gets rekindled every time we sit down to read something really excellent.

the “theory of maximum taste.” This theory is based on the idea that exposure to genius has the power to expand your consciousness. If you spend a lot of time with genius, your mind will end up bigger and broader than if you spend your time only with run-of-the-mill stuff.

the whole culture is eroding the skill the UCLA scholar Maryanne Wolf calls “deep literacy,” the ability to deeply engage in a dialectical way with a text or piece of philosophy, literature, or art.

“To the extent that you cannot perceive the world in its fullness, to the same extent you will fall back into mindless, repetitive, self-reinforcing behavior, unable to escape.”

I can’t say that to you, because it sounds fussy and elitist and OK Boomer. And if you were in front of me, you’d roll your eyes.

Industry leaders believe the new A.I. systems could be as important as the introduction of the web browser in the early 1990s and could lead to breakthroughs in areas ranging from drug research to education.

But gnawing at many industry insiders is a fear that they are releasing something dangerous into the wild. Generative A.I. can already be a tool for misinformation. Soon, it could be a risk to jobs. Somewhere down the line, tech’s biggest worriers say, it could be a risk to humanity.

“It is hard to see how you can prevent the bad actors from using it for bad things,” Dr. Hinton said.

After the San Francisco start-up OpenAI released a new version of ChatGPT in March, more than 1,000 technology leaders and researchers signed an open letter calling for a six-month moratorium on the development of new systems because A.I technologies pose “profound risks to society and humanity.

Several days later, 19 current and former leaders of the Association for the Advancement of Artificial Intelligence, a 40-year-old academic society, released their own letter warning of the risks of A.I. That group included Eric Horvitz, chief scientific officer at Microsoft, which has deployed OpenAI’s technology across a wide range of products, including its Bing search engine.

Dr. Hinton, often called “the Godfather of A.I.,” did not sign either of those letters and said he did not want to publicly criticize Google or other companies until he had quit his job

Dr. Hinton, a 75-year-old British expatriate, is a lifelong academic whose career was driven by his personal convictions about the development and use of A.I. In 1972, as a graduate student at the University of Edinburgh, Dr. Hinton embraced an idea called a neural network. A neural network is a mathematical system that learns skills by analyzing data. At the time, few researchers believed in the idea. But it became his life’s work.

Dr. Hinton is deeply opposed to the use of artificial intelligence on the battlefield — what he calls “robot soldiers.”

In 2012, Dr. Hinton and two of his students in Toronto, Ilya Sutskever and Alex Krishevsky, built a neural network that could analyze thousands of photos and teach itself to identify common objects, such as flowers, dogs and cars.

In 2018, Dr. Hinton and two other longtime collaborators received the Turing Award, often called “the Nobel Prize of computing,” for their work on neural networks.

Around the same time, Google, OpenAI and other companies began building neural networks that learned from huge amounts of digital text. Dr. Hinton thought it was a powerful way for machines to understand and generate language, but it was inferior to the way humans handled language.

Then, last year, as Google and OpenAI built systems using much larger amounts of data, his view changed. He still believed the systems were inferior to the human brain in some ways but he thought they were eclipsing human intelligence in others.

“Maybe what is going on in these systems,” he said, “is actually a lot better than what is going on in the brain.”

As companies improve their A.I. systems, he believes, they become increasingly dangerous. “Look at how it was five years ago and how it is now,” he said of A.I. technology. “Take the difference and propagate it forwards. That’s scary.”

Until last year, he said, Google acted as a “proper steward” for the technology, careful not to release something that might cause harm. But now that Microsoft has augmented its Bing search engine with a chatbot — challenging Google’s core business — Google is racing to deploy the same kind of technology. The tech giants are locked in a competition that might be impossible to stop, Dr. Hinton said.

His immediate concern is that the internet will be flooded with false photos, videos and text, and the average person will “not be able to know what is true anymore.”

He is also worried that A.I. technologies will in time upend the job market. Today, chatbots like ChatGPT tend to complement human workers, but they could replace paralegals, personal assistants, translators and others who handle rote tasks. “It takes away the drudge work,” he said. “It might take away more than that.”

Down the road, he is worried that future versions of the technology pose a threat to humanity because they often learn unexpected behavior from the vast amounts of data they analyze. This becomes an issue, he said, as individuals and companies allow A.I. systems not only to generate their own computer code but actually run that code on their ow

And he fears a day when truly autonomous weapons — those killer robots — become reality.

“The idea that this stuff could actually get smarter than people — a few people believed that,” he said. “But most people thought it was way off. And I thought it was way off. I thought it was 30 to 50 years or even longer away. Obviously, I no longer think that.”

Many other experts, including many of his students and colleagues, say this threat is hypothetical. But Dr. Hinton believes that the race between Google and Microsoft and others will escalate into a global race that will not stop without some sort of global regulation.

But that may be impossible, he said. Unlike with nuclear weapons, he said, there is no way of knowing whether companies or countries are working on the technology in secret. The best hope is for the world’s leading scientists to collaborate on ways of controlling the technology. “I don’t think they should scale this up more until they have understood whether they can control it,” he said.

Dr. Hinton said that when people used to ask him how he could work on technology that was potentially dangerous, he would paraphrase Robert Oppenheimer, who led the U.S. effort to build the atomic bomb: “When you see something that is technically sweet, you go ahead and do it.”

He does not say that anymore.

In the early 1990s, The Journal sent me on many reporting trips to the U.S.S.R.

I saw but did not see the enormous amount of corruption that was going on. I saw but did not see that property rights alone do not spontaneously make a decent society. The primary problem in all societies is order — moral, legal and social order.

By the time I came to this job, in 2003, I was having qualms about the free-market education I’d received — but not fast enough. It took me a while to see that the postindustrial capitalism machine — while innovative, dynamic and wonderful in many respects — had some fundamental flaws.

The most educated Americans were amassing more and more wealth, dominating the best living areas, pouring advantages into their kids. A highly unequal caste system was forming. Bit by bit it dawned on me that the government would have to get much more active if every child was going to have an open field and a fair chance.

the financial crisis hit, the flaws in modern capitalism were blindingly obvious, but my mental frames still didn’t shift fast enough.

Sometimes in life you should stick to your worldview and defend it against criticism. But sometimes the world is genuinely different than it was before. At those moments the crucial skills are the ones nobody teaches you: how to reorganize your mind, how to see with new eyes.
