His theory draws upon many of the most prominent views of how humans emerged. These range from our evolution of the ability to run long distances to our development of the earliest weapons, which involved the improvement of hand-eye coordination. Dramatic climate change in Africa over the course of a few tens of thousands of years also may have forced Australopithecus and Homo to adapt rapidly. And over roughly the same span, humans became cooperative hunters and serious meat eaters, vastly enriching our diet and favoring the development of more-robust brains. By themselves, Wilson says, none of these theories is satisfying. Taken together, though, all of these factors pushed our immediate prehuman ancestors toward what he called a huge pre-adaptive step: the formation of the earliest communities around fixed camps.

“When humans started having a camp—and we know that Homo erectus had campsites—then we know they were heading somewhere,” he told me. “They were a group progressively provisioned, sending out some individuals to hunt and some individuals to stay back and guard the valuable campsite. They were no longer just wandering through territory, emitting calls. They were on long-term campsites, maybe changing from time to time, but they had come together. They began to read intentions in each other’s behavior, what each other are doing. They started to learn social connections more solidly.”

“The humans become consistent with all the others,” he said, and the evolutionary steps were likely similar—beginning with the formation of groups within a freely mixing population, followed by the accumulation of pre-adaptations that make eusociality more likely, such as the invention of campsites. Finally comes the rise to prevalence of eusocial alleles—one of two or more alternative forms of a gene that arise by mutation, and are found at the same place on a chromosome—which promote novel behaviors (like communal child care) or suppress old, asocial traits. Now it is up to geneticists, he adds, to “determine how many genes are involved in crossing the eusociality threshold, and to go find those genes.”

Wilson posits that two rival forces drive human behavior: group selection and what he calls “individual selection”—competition at the level of the individual to pass along one’s genes—with both operating simultaneously. “Group selection,” he said, “brings about virtue, and—this is an oversimplification, but—individual selection, which is competing with it, creates sin. That, in a nutshell, is an explanation of the human condition.

“Within groups, the selfish are more likely to succeed,” Wilson told me in a telephone conversation. “But in competition between groups, groups of altruists are more likely to succeed. In addition, it is clear that groups of humans proselytize other groups and accept them as allies, and that that tendency is much favored by group selection.” Taking in newcomers and forming alliances had become a fundamental human trait, he added, because “it is a good way to win.”

If Wilson is right, the human impulse toward racism and tribalism could come to be seen as a reflection of our genetic nature as much as anything else—but so could the human capacity for altruism, and for coalition- and alliance-building. These latter possibilities may help explain Wilson’s abiding optimism—about the environment and many other matters. If these traits are indeed deeply written into our genetic codes, we might hope that we can find ways to emphasize and reinforce them, to build problem-solving coalitions that can endure, and to identify with progressively larger and more-inclusive groups over time.

chemical communication between humans in laboratory experiments

Whether pheromones play a role in human life outside the lab remains unknown. In animals pheromones affect the whole panoply of behavior - mating, aggression and fear.

rats that fear change have shorter lives than their more flexible counterparts, and that social isolation can also affect the longevity of rodents

the social and psychological world changes the fundamental mechanisms of biology, and vice versa

I've tried to situate biology in a rich social and psychological context and make it simple.

the chemosignal. Molecules produced by a person or animal that can change behaviors of others, even though they are not detected as an odor.

for two months, we exposed nonlactating women to this breast-feeding compound, which is found naturally in nursing mothers and infants. Women with regular sex partners reported a 24 percent increase in sexual desire; those without partners increased their sexual fantasies by 17 percent

When the study drew attention and controversy, there was a moment when they both could have said: "We didn't look carefully enough at this the first time. Now we can see that it doesn't meet our standards." Instead they allowed Facebook and the PR people to take the lead in responding to the controversy.

What should this reality signal to Facebook users? Is it time to pull-back? You have (almost) no rights. You have (almost) no control. You have no idea what they're doing to you or with you. You don't even know who's getting the stuff you are posting, and you're not allowed to know. Trade secret!

Are there any particular warnings here for journalists and editors in terms of their exposure on Facebook? Yeah. Facebook has all the power. You have almost none. Just keep that in mind in all your dealings with it, as an individual with family and friends, as a journalist with a story to file, and as a news organization that is "on" Facebook.

I am not in a commercial situation where I have to maximize my traffic, so I can opt out. Right now my choice is to keep my account, but use it cynically. 

does this level of experimentation indicate the prospect of a further undermining of audience-driven news priorities and traditional news values? The right way to think about it is a loss of power—for news producers and their priorities. As I said, Facebook thinks it knows better than I do what "my" 180,000 subscribers should get from me.

Facebook has "where else are they going to go?" logic now. And they have good reason for this confidence. (It's called network effects.) But "where else are they going to go?" is a long way from trust and loyalty. It is less a durable business model than a statement of power. 

I distinguished between the "thin" legitimacy that Facebook operates under and the "thick" legitimacy that the university requires to be the institution it was always supposed to be. (Both are distinct from il-legitimacy.) News organizations should learn to make this distinction more often. Normal PR exists to muddle it. Which is why you don't hand a research crisis over to university PR people.

some commentators have questioned the practice of A/B headline testing in the aftermath of this scandal—is there a clear connection? The connection to me is that both are forms of behaviourism. Behaviourism is a view of human beings in which, as Hannah Arendt said, they are reduced to the level of a conditioned and "behaving" animal—an animal that responds to these stimuli but not those. This is why a popular shorthand for Facebook's study was that users were being treated as lab rats.

Journalism is supposed to be about informing people so they can understand the world and take action when necessary. Action and behaviour are not the same thing at all. One is a conscious choice, the other a human tendency. There's a tension, then, between commercial behaviourism, which may be deeply functional in some ways for the news industry, and informing people as citizens capable of understanding their world well enough to improve it, which is the deepest purpose of journalism. A/B testing merely highlights this tension.

“The net is designed to be an interruption system, a machine geared to dividing attention,” Nicholas Carr explains in his book “The Shallows: What the Internet Is Doing to Our Brains.” “We willingly accept the loss of concentration and focus, the division of our attention and the fragmentation of our thoughts, in return for the wealth of compelling or at least diverting information we receive.”

Addiction is the relentless pull to a substance or an activity that becomes so compulsive it ultimately interferes with everyday life

Denial is any addict’s first defense. No obstacle to recovery is greater than the infinite capacity to rationalize our compulsive behaviors

According to one recent survey, the average white-collar worker spends about six hours a day on email.

The brain’s craving for novelty, constant stimulation and immediate gratification creates something called a “compulsion loop.” Like lab rats and drug addicts, we need more and more to get the same effect.

Endless access to new information also easily overloads our working memory. When we reach cognitive overload, our ability to transfer learning to long-term memory significantly deteriorates.

By that definition, nearly everyone I know is addicted in some measure to the Internet. It has arguably replaced work itself as our most socially sanctioned addictio

t we humans have a very limited reservoir of will and discipline. We’re far more likely to succeed by trying to change one behavior at a time, ideally at the same time each day, so that it becomes a habit, requiring less and less energy to sustain.

Now it was time to detox. I interpreted the traditional second step — belief that a higher power could help restore my sanity — in a more secular way. The higher power became my 30-year-old daughter, who disconnected my phone and laptop from both my email and the Web.

During those first few days, I did suffer withdrawal pangs, most of all the hunger to call up Google and search for an answer to some question that arose. But with each passing day offline, I felt more relaxed, less anxious, more able to focus and less hungry for the next shot of instant but short-lived stimulation. What happened to my brain is exactly what I hoped would happen: It began to quiet down.

I had brought more than a dozen books of varying difficulty and length on my vacation. I started with short nonfiction, and then moved to longer nonfiction as I began to feel calmer and my focus got stronger. I eventually worked my way up to “The Emperor of All Maladies

I am back at work now, and of course I am back online. The Internet isn’t going away, and it will continue to consume a lot of my attention. My aim now is to find the best possible balance between time online and time off

I also make it my business now to take on more fully absorbing activities as part of my days. Above all, I’ve kept up reading books, not just because I love them, but also as a continuing attention-building practice.

I’ve retained my longtime ritual of deciding the night before on the most important thing I can accomplish the next morning. That’s my first work activity most days, for 60 to 90 minutes without interruption. Afterward, I take a 10- to 15-minute break to quiet my mind and renew my energy.

If I have other work during the day that requires sustained focus, I go completely offline for designated periods, repeating my morning ritual. In the evening, when I go up to my bedroom, I nearly always leave my digital devices downstairs.

The technique holds the power to repair or enhance any human gene. “It raises the most fundamental of issues about how we are going to view our humanity in the future and whether we are going to take the dramatic step of modifying our own germline and in a sense take control of our genetic destiny, which raises enormous peril for humanity,”

The paper’s authors, however, are concerned about countries that have less regulation in science. They urge that “scientists should avoid even attempting, in lax jurisdictions, germline genome modification for clinical application in humans” until the full implications “are discussed among scientific and governmental organizations.”

Though such a moratorium would not be legally enforceable and might seem unlikely to exert global influence, there is a precedent. In 1975, scientists worldwide were asked to refrain from using a method for manipulating genes, the recombinant DNA technique, until rules had been established.

Though highly efficient, the technique occasionally cuts the genome at unintended sites. The issue of how much mistargeting could be tolerated in a clinical setting is one that Dr. Doudna’s group wants to see thoroughly explored before any human genome is edited.

“We worry about people making changes without the knowledge of what those changes mean in terms of the overall genome,” Dr. Baltimore said. “I personally think we are just not smart enough — and won’t be for a very long time — to feel comfortable about the consequences of changing heredity, even in a single individual.”

Many ethicists have accepted the idea of gene therapy, changes that die with the patient, but draw a clear line at altering the germline, since these will extend to future generations. The British Parliament in February approved the transfer of mitochondria, small DNA-containing organelles, to human eggs whose own mitochondria are defective. But that technique is less far-reaching because no genes are edited.

There are two broad schools of thought on modifying the human germline, said R. Alta Charo, a bioethicist at the University of Wisconsin and a member of the Doudna group. One is pragmatic and seeks to balance benefit and risk. The other “sets up inherent limits on how much humankind should alter nature,” she said. Some Christian doctrines oppose the idea of playing God, whereas in Judaism and Islam there is the notion “that humankind is supposed to improve the world.” She described herself as more of a pragmatist, saying, “I would try to regulate such things rather than shut a new technology down at its beginning.

The Doudna group calls for public discussion, but is also working to develop some more formal process, such as an international meeting convened by the National Academy of Sciences, to establish guidelines for human use of the genome-editing technique.“We need some principled agreement that we want to enhance humans in this way or we don’t,” Dr. Jaenisch said. “You have to have this discussion because people are gearing up to do this.”

What none of these parents understand is that their children’s and teens’ destructive obsession with technology is the predictable consequence of a virtually unrecognized merger between the tech industry and psychology.

Dr. B.J. Fogg, is a psychologist and the father of persuasive technology, a discipline in which digital machines and apps — including smartphones, social media, and video games — are configured to alter human thoughts and behaviors. As the lab’s website boldly proclaims: “Machines designed to change humans.”

These parents have no idea that lurking behind their kids’ screens and phones are a multitude of psychologists, neuroscientists, and social science experts who use their knowledge of psychological vulnerabilities to devise products that capture kids’ attention for the sake of industry profit.

psychology — a discipline that we associate with healing — is now being used as a weapon against children.

This alliance pairs the consumer tech industry’s immense wealth with the most sophisticated psychological research, making it possible to develop social media, video games, and phones with drug-like power to seduce young users.

Likewise, social media companies use persuasive design to prey on the age-appropriate desire for preteen and teen kids, especially girls, to be socially successful. This drive is built into our DNA, since real-world relational skills have fostered human evolution.

Called “the millionaire maker,” Fogg has groomed former students who have used his methods to develop technologies that now consume kids’ lives. As he recently touted on his personal website, “My students often do groundbreaking projects, and they continue having impact in the real world after they leave Stanford… For example, Instagram has influenced the behavior of over 800 million people. The co-founder was a student of mine.”

Persuasive technology (also called persuasive design) works by deliberately creating digital environments that users feel fulfill their basic human drives — to be social or obtain goals — better than real-world alternatives.

Kids spend countless hours in social media and video game environments in pursuit of likes, “friends,” game points, and levels — because it’s stimulating, they believe that this makes them happy and successful, and they find it easier than doing the difficult but developmentally important activities of childhood.

While persuasion techniques work well on adults, they are particularly effective at influencing the still-maturing child and teen brain.

“Video games, better than anything else in our culture, deliver rewards to people, especially teenage boys,” says Fogg. “Teenage boys are wired to seek competency. To master our world and get better at stuff. Video games, in dishing out rewards, can convey to people that their competency is growing, you can get better at something second by second.”

it’s persuasive design that’s helped convince this generation of boys they are gaining “competency” by spending countless hours on game sites, when the sad reality is they are locked away in their rooms gaming, ignoring school, and not developing the real-world competencies that colleges and employers demand.

Persuasive technologies work because of their apparent triggering of the release of dopamine, a powerful neurotransmitter involved in reward, attention, and addiction.

As she says, “If you don’t get 100 ‘likes,’ you make other people share it so you get 100…. Or else you just get upset. Everyone wants to get the most ‘likes.’ It’s like a popularity contest.”

there are costs to Casey’s phone obsession, noting that the “girl’s phone, be it Facebook, Instagram or iMessage, is constantly pulling her away from her homework, sleep, or conversations with her family.

Casey says she wishes she could put her phone down. But she can’t. “I’ll wake up in the morning and go on Facebook just… because,” she says. “It’s not like I want to or I don’t. I just go on it. I’m, like, forced to. I don’t know why. I need to. Facebook takes up my whole life.”

B.J. Fogg may not be a household name, but Fortune Magazine calls him a “New Guru You Should Know,” and his research is driving a worldwide legion of user experience (UX) designers who utilize and expand upon his models of persuasive design.

“No one has perhaps been as influential on the current generation of user experience (UX) designers as Stanford researcher B.J. Fogg.”

the core of UX research is about using psychology to take advantage of our human vulnerabilities.

As Fogg is quoted in Kosner’s Forbes article, “Facebook, Twitter, Google, you name it, these companies have been using computers to influence our behavior.” However, the driving force behind behavior change isn’t computers. “The missing link isn’t the technology, it’s psychology,” says Fogg.

UX researchers not only follow Fogg’s design model, but also his apparent tendency to overlook the broader implications of persuasive design. They focus on the task at hand, building digital machines and apps that better demand users’ attention, compel users to return again and again, and grow businesses’ bottom line.

the “Fogg Behavior Model” is a well-tested method to change behavior and, in its simplified form, involves three primary factors: motivation, ability, and triggers.

“We can now create machines that can change what people think and what people do, and the machines can do that autonomously.”

Regarding ability, Fogg suggests that digital products should be made so that users don’t have to “think hard.” Hence, social networks are designed for ease of use

Finally, Fogg says that potential users need to be triggered to use a site. This is accomplished by a myriad of digital tricks, including the sending of incessant notifications

moral questions about the impact of turning persuasive techniques on children and teens are not being asked. For example, should the fear of social rejection be used to compel kids to compulsively use social media? Is it okay to lure kids away from school tasks that demand a strong mental effort so they can spend their lives on social networks or playing video games that don’t make them think much at all?

Describing how his formula is effective at getting people to use a social network, the psychologist says in an academic paper that a key motivator is users’ desire for “social acceptance,” although he says an even more powerful motivator is the desire “to avoid being socially rejected.”

the startup Dopamine Labs boasts about its use of persuasive techniques to increase profits: “Connect your app to our Persuasive AI [Artificial Intelligence] and lift your engagement and revenue up to 30% by giving your users our perfect bursts of dopamine,” and “A burst of Dopamine doesn’t just feel good: it’s proven to re-wire user behavior and habits.”

Ramsay Brown, the founder of Dopamine Labs, says in a KQED Science article, “We have now developed a rigorous technology of the human mind, and that is both exciting and terrifying. We have the ability to twiddle some knobs in a machine learning dashboard we build, and around the world hundreds of thousands of people are going to quietly change their behavior in ways that, unbeknownst to them, feel second-nature but are really by design.”

Programmers call this “brain hacking,” as it compels users to spend more time on sites even though they mistakenly believe it’s strictly due to their own conscious choices.

Banks of computers employ AI to “learn” which of a countless number of persuasive design elements will keep users hooked

A persuasion profile of a particular user’s unique vulnerabilities is developed in real time and exploited to keep users on the site and make them return again and again for longer periods of time. This drives up profits for consumer internet companies whose revenue is based on how much their products are used.

“The leaders of Internet companies face an interesting, if also morally questionable, imperative: either they hijack neuroscience to gain market share and make large profits, or they let competitors do that and run away with the market.”

Social media and video game companies believe they are compelled to use persuasive technology in the arms race for attention, profits, and survival.

Children’s well-being is not part of the decision calculus.

one breakthrough occurred in 2017 when Facebook documents were leaked to The Australian. The internal report crafted by Facebook executives showed the social network boasting to advertisers that by monitoring posts, interactions, and photos in real time, the network is able to track when teens feel “insecure,” “worthless,” “stressed,” “useless” and a “failure.”

The report also bragged about Facebook’s ability to micro-target ads down to “moments when young people need a confidence boost.”

These design techniques provide tech corporations a window into kids’ hearts and minds to measure their particular vulnerabilities, which can then be used to control their behavior as consumers. This isn’t some strange future… this is now.

The official tech industry line is that persuasive technologies are used to make products more engaging and enjoyable. But the revelations of industry insiders can reveal darker motives.

Revealing the hard science behind persuasive technology, Hopson says, “This is not to say that players are the same as rats, but that there are general rules of learning which apply equally to both.”

After penning the paper, Hopson was hired by Microsoft, where he helped lead the development of the Xbox Live, Microsoft’s online gaming system

“If game designers are going to pull a person away from every other voluntary social activity or hobby or pastime, they’re going to have to engage that person at a very deep level in every possible way they can.”

This is the dominant effect of persuasive design today: building video games and social media products so compelling that they pull users away from the real world to spend their lives in for-profit domains.

Persuasive technologies are reshaping childhood, luring kids away from family and schoolwork to spend more and more of their lives sitting before screens and phones.

“Since we’ve figured to some extent how these pieces of the brain that handle addiction are working, people have figured out how to juice them further and how to bake that information into apps.”

Today, persuasive design is likely distracting adults from driving safely, productive work, and engaging with their own children — all matters which need urgent attention

Still, because the child and adolescent brain is more easily controlled than the adult mind, the use of persuasive design is having a much more hurtful impact on kids.

But to engage in a pursuit at the expense of important real-world activities is a core element of addiction.

younger U.S. children now spend 5 ½ hours each day with entertainment technologies, including video games, social media, and online videos.

Even more, the average teen now spends an incredible 8 hours each day playing with screens and phones

U.S. kids only spend 16 minutes each day using the computer at home for school.

Quietly, using screens and phones for entertainment has become the dominant activity of childhood.

Younger kids spend more time engaging with entertainment screens than they do in school

teens spend even more time playing with screens and phones than they do sleeping

kids are so taken with their phones and other devices that they have turned their backs to the world around them.

many children are missing out on real-life engagement with family and school — the two cornerstones of childhood that lead them to grow up happy and successful

persuasive technologies are pulling kids into often toxic digital environments

A too frequent experience for many is being cyberbullied, which increases their risk of skipping school and considering suicide.

And there is growing recognition of the negative impact of FOMO, or the fear of missing out, as kids spend their social media lives watching a parade of peers who look to be having a great time without them, feeding their feelings of loneliness and being less than.

The combined effects of the displacement of vital childhood activities and exposure to unhealthy online environments is wrecking a generation.

as the typical age when kids get their first smartphone has fallen to 10, it’s no surprise to see serious psychiatric problems — once the domain of teens — now enveloping young kids

Self-inflicted injuries, such as cutting, that are serious enough to require treatment in an emergency room, have increased dramatically in 10- to 14-year-old girls, up 19% per year since 2009.

While girls are pulled onto smartphones and social media, boys are more likely to be seduced into the world of video gaming, often at the expense of a focus on school

it’s no surprise to see this generation of boys struggling to make it to college: a full 57% of college admissions are granted to young women compared with only 43% to young men.

Economists working with the National Bureau of Economic Research recently demonstrated how many young U.S. men are choosing to play video games rather than join the workforce.

The destructive forces of psychology deployed by the tech industry are making a greater impact on kids than the positive uses of psychology by mental health providers and child advocates. Put plainly, the science of psychology is hurting kids more than helping them.

Hope for this wired generation has seemed dim until recently, when a surprising group has come forward to criticize the tech industry’s use of psychological manipulation: tech executives

Tristan Harris, formerly a design ethicist at Google, has led the way by unmasking the industry’s use of persuasive design. Interviewed in The Economist’s 1843 magazine, he says, “The job of these companies is to hook people, and they do that by hijacking our psychological vulnerabilities.”

Marc Benioff, CEO of the cloud computing company Salesforce, is one of the voices calling for the regulation of social media companies because of their potential to addict children. He says that just as the cigarette industry has been regulated, so too should social media companies. “I think that, for sure, technology has addictive qualities that we have to address, and that product designers are working to make those products more addictive, and we need to rein that back as much as possible,”

“If there’s an unfair advantage or things that are out there that are not understood by parents, then the government’s got to come forward and illuminate that.”

Since millions of parents, for example the parents of my patient Kelly, have absolutely no idea that devices are used to hijack their children’s minds and lives, regulation of such practices is the right thing to do.

Another improbable group to speak out on behalf of children is tech investors.

How has the consumer tech industry responded to these calls for change? By going even lower.

Facebook recently launched Messenger Kids, a social media app that will reach kids as young as five years old. Suggestive that harmful persuasive design is now honing in on very young children is the declaration of Messenger Kids Art Director, Shiu Pei Luu, “We want to help foster communication [on Facebook] and make that the most exciting thing you want to be doing.”

the American Psychological Association (APA) — which is tasked with protecting children and families from harmful psychological practices — has been essentially silent on the matter

APA Ethical Standards require the profession to make efforts to correct the “misuse” of the work of psychologists, which would include the application of B.J. Fogg’s persuasive technologies to influence children against their best interests

Manipulating children for profit without their own or parents’ consent, and driving kids to spend more time on devices that contribute to emotional and academic problems is the embodiment of unethical psychological practice.

“Never before in history have basically 50 mostly men, mostly 20–35, mostly white engineer designer types within 50 miles of where we are right now [Silicon Valley], had control of what a billion people think and do.”

Some may argue that it’s the parents’ responsibility to protect their children from tech industry deception. However, parents have no idea of the powerful forces aligned against them, nor do they know how technologies are developed with drug-like effects to capture kids’ minds

Others will claim that nothing should be done because the intention behind persuasive design is to build better products, not manipulate kids

similar circumstances exist in the cigarette industry, as tobacco companies have as their intention profiting from the sale of their product, not hurting children. Nonetheless, because cigarettes and persuasive design predictably harm children, actions should be taken to protect kids from their effects.

in a 1998 academic paper, Fogg describes what should happen if things go wrong, saying, if persuasive technologies are “deemed harmful or questionable in some regard, a researcher should then either take social action or advocate that others do so.”

I suggest turning to President John F. Kennedy’s prescient guidance: He said that technology “has no conscience of its own. Whether it will become a force for good or ill depends on man.”

The APA should begin by demanding that the tech industry’s behavioral manipulation techniques be brought out of the shadows and exposed to the light of public awareness

Changes should be made in the APA’s Ethics Code to specifically prevent psychologists from manipulating children using digital machines, especially if such influence is known to pose risks to their well-being.

Moreover, the APA should follow its Ethical Standards by making strong efforts to correct the misuse of psychological persuasion by the tech industry and by user experience designers outside the field of psychology.

It should join with tech executives who are demanding that persuasive design in kids’ tech products be regulated

The APA also should make its powerful voice heard amongst the growing chorus calling out tech companies that intentionally exploit children’s vulnerabilities.

The idea behind the class is deceptively simple, and many of the lessons — such as gratitude, helping others, getting enough sleep — are familiar.

“A lot of people are waking up, realizing that we’re struggling,

All semester, hundreds of students tried to rewire themselves — to exercise more, to thank their mothers, to care less about the final grade and more about the ideas.

But in ways small and large, silly and heartbreakingly earnest, simple and profound, this class changed the conversation at Yale. It surfaced in late-night talks in dorms, it was dissected in newspaper columns, it popped up, again and again, in memes.

It’s the application that’s difficult, a point Santos made repeatedly: Our brains often lead us to bad choices, and even when we realize the choices are bad, it’s hard to break habits.

In a way, the class is the very essence of a liberal-arts education: learning, exploration, insight into oneself and the world. But many students described it as entirely unlike any class they had ever taken — nothing to do with academics, and everything to do with life.

There’s no longer the same stigma around mental-health issues, he said. “Now, so many people are admitting they want to lead happier lives.”

The impact is not limited to Yale. Stories about PSYC157 spread around the world. Santos created a pared-down version of the class and offered it to anyone on the online education site Coursera.

She taught students about cognitive biases.

“We called it the ways in which our minds suck,” Forti said. “Our minds make us think that certain things make us happy, but they don’t.”

Then, they had to apply the lessons

There was a palpable difference on campus, several students said, during the week when they performed random acts of kindness.

The biggest misconception people have about the class is that Santos is offering some kind of easy happiness fix. “It’s something you have to work on every day. . . . If I keep using these skills, they’ll, over time, help me develop better habits and be happier.

So many students have told her the class changed their lives. “If you’re really grateful, show me that,” she told them. “Change the culture.

for now students stood and clapped and clapped and clapped, beaming, drowning out even Kanye with their standing ovation. As if they had nothing but time.

Before he died, Richard Feynman, who understood quantum theory as well as anyone, said, “I still get nervous with it...I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.” The problem is not with using the theory — making calculations, applying it to engineering tasks — but in understanding what it means. What does it tell us about the world?

From one point of view, quantum physics is just a set of formalisms, a useful tool kit. Want to make better lasers or transistors or television sets? The Schrödinger equation is your friend. The trouble starts only when you step back and ask whether the entities implied by the equation can really exist. Then you encounter problems that can be described in several familiar ways:

Wave-particle duality. Everything there is — all matter and energy, all known forces — behaves sometimes like waves, smooth and continuous, and sometimes like particles, rat-a-tat-tat. Electricity flows through wires, like a fluid, or flies through a vacuum as a volley of individual electrons. Can it be both things at once?

The uncertainty principle. Werner Heisenberg famously discovered that when you measure the position (let’s say) of an electron as precisely as you can, you find yourself more and more in the dark about its momentum. And vice versa. You can pin down one or the other but not both.

The measurement problem. Most of quantum mechanics deals with probabilities rather than certainties. A particle has a probability of appearing in a certain place. An unstable atom has a probability of decaying at a certain instant. But when a physicist goes into the laboratory and performs an experiment, there is a definite outcome. The act of measurement — observation, by someone or something — becomes an inextricable part of the theory

The strange implication is that the reality of the quantum world remains amorphous or indefinite until scientists start measuring

Other interpretations rely on “hidden variables” to account for quantities presumed to exist behind the curtain.

This is disturbing to philosophers as well as physicists. It led Einstein to say in 1952, “The theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.”

“Figuring out what quantum physics is saying about the world has been hard,” Becker says, and this understatement motivates his book, a thorough, illuminating exploration of the most consequential controversy raging in modern science.

In a way, the Copenhagen is an anti-interpretation. “It is wrong to think that the task of physics is to find out how nature is,” Bohr said. “Physics concerns what we can say about nature.”

Nothing is definite in Bohr’s quantum world until someone observes it. Physics can help us order experience but should not be expected to provide a complete picture of reality. The popular four-word summary of the Copenhagen interpretation is: “Shut up and calculate!”

Becker sides with the worriers. He leads us through an impressive account of the rise of competing interpretations, grounding them in the human stories

He makes a convincing case that it’s wrong to imagine the Copenhagen interpretation as a single official or even coherent statement. It is, he suggests, a “strange assemblage of claims.

An American physicist, David Bohm, devised a radical alternative at midcentury, visualizing “pilot waves” that guide every particle, an attempt to eliminate the wave-particle duality.

Competing approaches to quantum foundations are called “interpretations,” and nowadays there are many. The first and still possibly foremost of these is the so-called Copenhagen interpretation.

Perhaps the most popular lately — certainly the most talked about — is the “many-worlds interpretation”: Every quantum event is a fork in the road, and one way to escape the difficulties is to imagine, mathematically speaking, that each fork creates a new universe

if you think the many-worlds idea is easily dismissed, plenty of physicists will beg to differ. They will tell you that it could explain, for example, why quantum computers (which admittedly don’t yet quite exist) could be so powerful: They would delegate the work to their alter egos in other universes.

When scientists search for meaning in quantum physics, they may be straying into a no-man’s-land between philosophy and religion. But they can’t help themselves. They’re only human.

If you were to watch me by day, you would see me sitting at my desk solving Schrödinger’s equation...exactly like my colleagues,” says Sir Anthony Leggett, a Nobel Prize winner and pioneer in superfluidity. “But occasionally at night, when the full moon is bright, I do what in the physics community is the intellectual equivalent of turning into a werewolf: I question whether quantum mechanics is the complete and ultimate truth about the physical universe.”

forgetting seems to be an active mechanism that is constantly at work in the brain.

“To have proper memory function, you have to have forgetting.

Different types of memory are created and stored in varying ways, and in various areas of the brain.

Neurons communicate with each other through synapses — junctions between these cells that include a tiny gap across which chemical messengers can be sent

The more often a memory is recalled, the stronger its neural network becomes. Over time, and through consistent recall, the memory becomes encoded in both the hippocampus and the cortex

Because the hippocampus is not where long-term memories are stored in the brain, its dynamic nature is not a flaw but a feature

Neuroscientists often refer to this physical representation of a memory as an engram. They think that each engram has a number of synaptic connections, sometimes even in several areas of the brain, and that each neuron and synapse can be involved in multiple engrams

The brain is always trying to forget the information it’s already learnt,

Hardt’s lab showed that a dedicated mechanism continuously promotes the expression of AMPA receptors at synapses.

To forget certain things, it seemed that the rat brain had to proactively destroy connections at the synapse. Forgetting, Hardt says, “is not a failure of memory, but a function of it”.

Paul Frankland, a neuroscientist at the Hospital for Sick Children in Toronto, Canada, had also found evidence that the brain is wired to forget

Frankland was studying the production of new neurons, or neurogenesis, in adult mice. The process had long been known to occur in the brains of young animals, but had been discovered in the hippocampi of mature animals only about 20 years earlier. Because the hippocampus is involved in memory formation, Frankland and his team wondered whether increasing neurogenesis in adult mice could help the rodents to remember.

Eventually, it exists independently in the cortex, where it is put away for long-term storage.

Researchers think that the human brain might operate in a similar way

Studies of people with exceptional autobiographical memories or with impaired ones seem to bear this out

People with a condition known as highly superior autobiographical memory (HSAM) remember their lives in such incredible detail that they can describe the outfit that they were wearing on any particular day

Those with severely deficient autobiographical memory (SDAM), however, are unable to vividly recall specific events in their lives

As a result, they also have trouble imagining what might happen in the future

By better understanding how we forget, through the lenses of both biology and cognitive psychology, Anderson and other researchers might be edging nearer to improving treatments for anxiety, PTSD and even Alzheimer’s disease

Hardt thinks that Alzheimer’s disease might also be better understood as a malfunction of forgetting rather than remembering

But more memory researchers are shifting their focus to examine how the brain forgets, as well as how it remembers

In the past decade, researchers have begun to view forgetting as an important part of a whole

Why do we have memory at all? As humans, we entertain this fantasy that it’s important to have autobiographical details,

Forgetting enables us as individuals, and as a species, to move forwards.

In short, Nader believes that the very act of remembering can change our memories

Much of his research is on rats, but he says the same basic principles apply to human memory as well. In fact, he says, it may be impossible for humans or any other animal to bring a memory to mind without altering it in some way.

Memories surrounding a major event like September 11 might be especially susceptible, he says, because we tend to replay them over and over in our minds and in conversation with others—with each repetition having the potential to alter them

cientists have long known that recording a memory requires adjusting the connections between neurons

Each memory tweaks some tiny subset of the neurons in the brain (the human brain has 100 billion neurons in all), changing the way they communicate. Neurons send messages to one another across narrow gaps called synapses

According to this view, the brain’s memory system works something like a pen and notebook. For a brief time before the ink dries, it’s possible to smudge what’s written

Researchers had found that a memory could be weakened if they gave an animal an electric shock or a drug that interferes with a particular neurotransmitter just after they prompted the animal to recall the memory. This suggested that memories were vulnerable to disruption even after they had been consolidated.

If memories are consolidated just once, when they are first created, he reasoned, the drug would have no effect on the rat’s memory of the tone or on the way it would respond to the tone in the future.

Perhaps it’s better if we can rewrite our memories every time we recall them. Nader suggests that reconsolidation may be the brain’s mechanism for recasting old memories in the light of everything that has happened since. In other words, it just might be what keeps us from living in the past.

When people think they’re multitasking, they’re actually just switching from one task to another very rapidly. And every time they do, there’s a cognitive cost in doing so.”

Even though we think we’re getting a lot done, ironically, multitasking makes us demonstrably less efficient.

Multitasking creates a dopamine-addiction feedback loop, effectively rewarding the brain for losing focus and for constantly searching for external stimulation.

The irony here for those of us who are trying to focus amid competing activities is clear: the very brain region we need to rely on for staying on task is easily distracted.

Instead of reaping the big rewards that come from sustained, focused effort, we instead reap empty rewards from completing a thousand little sugar-coated tasks.

His research found that being in a situation where you are trying to concentrate on a task, and an email is sitting unread in your inbox, can reduce your effective IQ by 10 points.

Wilson showed that the cognitive losses from multitasking are even greater than the cognitive losses from pot‑smoking.

If students study and watch TV at the same time, for example, the information from their schoolwork goes into the striatum, a region specialised for storing new procedures and skills, not facts and ideas. Without the distraction of TV, the information goes into the hippocampus, where it is organised and categorised in a variety of ways, making it easier to retrieve.

All this activity gives us a sense that we’re getting things done – and in some cases we are. But we are sacrificing efficiency and deep concentration when we interrupt our priority activities with email.

This uncertainty wreaks havoc with our rapid perceptual categorisation system, causes stress, and leads to decision overload. Every email requires a decision! Do I respond to it? If so, now or later? How important is it? What will be the social, economic, or job-related consequences if I don’t answer, or if I don’t answer right now?

A lever in the cage allowed the rats to send a small electrical signal directly to their nucleus accumbens. Do you think they liked it? Boy how they did! They liked it so much that they did nothing else. They forgot all about eating and sleeping. Long after they were hungry, they ignored tasty food if they had a chance to press that little chrome bar;

But remember, it is the dumb, novelty-seeking portion of the brain driving the limbic system that induces this feeling of pleasure, not the planning, scheduling, higher-level thought centres in the prefrontal cortex. Make no mistake: email-, Facebook- and Twitter-checking constitute a neural addiction.

upervised learning depends on annotated data: images, audio or text that is painstakingly labeled by hordes of workers. They circle people or outline bicycles on pictures of street traffic. The labeled data is fed to computer algorithms, teaching the algorithms what to look for. After ingesting millions of labeled images, the algorithms become expert at recognizing what they have been taught to see.

There is also reinforcement learning, with very limited supervision that does not rely on training data. Reinforcement learning in computer science,

is modeled after reward-driven learning in the brain: Think of a rat learning to push a lever to receive a pellet of food. The strategy has been developed to teach computer systems to take actions.

A more inclusive term for the future of A.I., he said, is “predictive learning,” meaning systems that not only recognize patterns but also p

redict outcomes and choose a course of action. “Everybody agrees we need predictive learning, but we disagree about how to get there,”

My money is on self-supervised learning,” he said, referring to computer systems that ingest huge amounts of unlabeled data and make sense of it all without supervision or reward. He is working on models that learn by observation, accumulating enough background knowledge that some sort of common sense can emerge.

A huge fraction of what we do in our day-to-day jobs is constantly refining our mental models of the world and then using those mental models to solve problems,” he said. “That encapsulates an awful lot of what we’d like A.I. to do.”Image

Currently, robots can operate only in well-defined environments with little variation.

“Our working assumption is that if we build sufficiently general algorithms, then all we really have to do, once that’s done, is to put them in robots that are out there in the real world doing real things,”

Biologists call this need “sleep pressure”: Stay up too late, build up sleep pressure. Feeling drowsy in the evenings? Of course you are—by being awake all day, you’ve been generating sleep pressure! But like “dark matter,” this is a name for something whose nature we do not yet understand.

The search for the hypnotoxin was not unsuccessful. There are a handful of substances clearly demonstrated to cause sleep—including a molecule called adenosine, which appears to build up in certain parts of the brains of waking rats, then drain away during slumber. Adenosine is particularly interesting because it is adenosine receptors that caffeine seems to work on.

For instance, if adenosine puts us under at the moment of transition from wakefulness to sleep, where does it come from? “Nobody knows,” remarks Michael Lazarus, a researcher at the institute who studies adenosine. Some people say it’s coming from neurons, some say it’s another class of brain cells. But there isn’t a consensus. At any rate, “this isn’t about storage,” says Yanagisawa. In other words, these substances themselves don’t seem to store information about sleep pressure. They are just a response to it.

A few years ago, the group discovered a mouse that just could not seem to get rid of its sleep pressure. Its EEGs suggested it lived a life of snoozy exhaustion, and mice that had been engineered to carry its mutation showed the same symptoms. “This mutant has more high-amplitude sleep waves than normal. It’s always sleep-deprived,” says Yanagisawa. The mutation was in a gene called SIK3. The longer the mutants stay awake, the more chemical tags the SIK3 protein accumulates. The researchers published their discovery of the SIK3 mutants, as well as another sleep mutant, in Nature in 2016.

An intriguing thesis is that possessing a strong sense of life purpose provides us with that latent power to persevere and take action, even in the face of daunting odds and potential adversity. This is related to, though not identical to, the concept of resilience: the ability to bounce back from losses, failures, and disappointments

The vicarious fear conditioning was not effective when the researchers attempted to train the monkeys to fear flowers.

how would they know the flowers weren’t harmful?

Then we developed the fear and avoidance of those snakes.

It isn’t clear how the American public-school system will survive the COVID years. Teachers, whose relative pay and status have been in decline for decades, are fleeing the field. In 2021, buckling under the stresses of the pandemic, nearly 1 million people quit jobs in public education, a 40 percent increase over the previous year.

These kids, and the investments that come with them, may never return—the beginning of a cycle of attrition that could continue long after the pandemic ends and leave public schools even more underfunded and dilapidated than before. “It’s an open question whether the public-school system will recover,” Steiner said. “That is a real concern for democratic education.”

The high-profile failings of public schools during the pandemic have become a political problem for Democrats, because of their association with unions, prolonged closures, and the pedagogy of social justice, which can become a form of indoctrination.

The party that stands for strong government services in the name of egalitarian principles supported the closing of schools far longer than either the science or the welfare of children justified, and it has been woefully slow to acknowledge how much this damaged the life chances of some of America’s most disadvantaged students.

Public education is too important to be left to politicians and ideologues. Public schools still serve about 90 percent of children across red and blue America.

Since the common-school movement in the early 19th century, the public school has had an exalted purpose in this country. It’s our core civic institution—not just because, ideally, it brings children of all backgrounds together in a classroom, but because it prepares them for the demands and privileges of democratic citizenship. Or at least, it needs to.

What is school for? This is the kind of foundational question that arises when a crisis shakes the public’s faith in an essential institution. “The original thinkers about public education were concerned almost to a point of paranoia about creating self-governing citizens,”

“Horace Mann went to his grave having never once uttered the phrase college- and career-ready. We’ve become more accustomed to thinking about the private ends of education. We’ve completely lost the habit of thinking about education as citizen-making.”

School can’t just be an economic sorting system. One reason we have a stake in the education of other people’s children is that they will grow up to be citizens.

Public education is meant not to mirror the unexamined values of a particular family or community, but to expose children to ways that other people, some of them long dead, think.

If the answer were simply to push more and more kids into college, the United States would be entering its democratic prime

So the question isn’t just how much education, but what kind. Is it quaint, or utopian, to talk about teaching our children to be capable of governing themselves?

The COVID era, with Donald Trump out of office but still in power and with battles over mask mandates and critical race theory convulsing Twitter and school-board meetings, shows how badly Americans are able to think about our collective problems—let alone read, listen, empathize, debate, reconsider, and persuade in the search for solutions.

democratic citizenship can, at least in part, be learned.

The history warriors build their metaphysics of national good or evil on a foundation of ignorance. In a 2019 survey, only 40 percent of Americans were able to pass the test that all applicants for U.S. citizenship must take, which asks questions like “Who did the United States fight in World War II?” and “We elect a President for how many years?” The only state in which a majority passed was Vermont.

he orthodoxies currently fighting for our children’s souls turn the teaching of U.S. history into a static and morally simple quest for some American essence. They proceed from celebration or indictment toward a final judgment—innocent or guilty—and bury either oppression or progress in a subordinate clause. The most depressing thing about this gloomy pedagogy of ideologies in service to fragile psyches is how much knowledge it takes away from students who already have so little

A central goal for history, social-studies, and civics instruction should be to give students something more solid than spoon-fed maxims—to help them engage with the past on its own terms, not use it as a weapon in the latest front of the culture wars.

Releasing them to do “research” in the vast ocean of the internet without maps and compasses, as often happens, guarantees that they will drown before they arrive anywhere.

The truth requires a grounding in historical facts, but facts are quickly forgotten without meaning and context

The goal isn’t just to teach students the origins of the Civil War, but to give them the ability to read closely, think critically, evaluate sources, corroborate accounts, and back up their claims with evidence from original documents.

This kind of instruction, which requires teachers to distinguish between exposure and indoctrination, isn’t easy; it asks them to be more sophisticated professionals than their shabby conditions and pay (median salary: $62,000, less than accountants and transit police) suggest we are willing to support.

To do that, we’ll need to help kids restore at least part of their crushed attention spans.

staring at a screen for hours is a heavy depressant, especially for teenagers.

we’ll look back on the amount of time we let our children spend online with the same horror that we now feel about earlier generations of adults who hooked their kids on smoking.

“It’s not a choice between tech or no tech,” Bill Tally, a researcher with the Education Development Center, told me. “The question is what tech infrastructure best enables the things we care about,” such as deep engagement with instructional materials, teachers, and other students.

The pandemic should have forced us to reassess what really matters in public school; instead, it’s a crisis that we’ve just about wasted.

Like learning to read as historians, learning to sift through the tidal flood of memes for useful, reliable information can emancipate children who have been heedlessly hooked on screens by the adults in their lives

Finally, let’s give children a chance to read books—good books. It’s a strange feature of all the recent pedagogical innovations that they’ve resulted in the gradual disappearance of literature from many classrooms.

The best way to interest young people in literature is to have them read good literature, and not just books that focus with grim piety on the contemporary social and psychological problems of teenagers.

We sell them insultingly short in thinking that they won’t read unless the subject is themselves. Mirrors are ultimately isolating; young readers also need windows, even if the view is unfamiliar, even if it’s disturbing

connection through language to universal human experience and thought is the reward of great literature, a source of empathy and wisdom.

The culture wars, with their atmosphere of resentment, fear, and petty faultfinding, are hostile to the writing and reading of literature.

W. E. B. Du Bois wrote: “Nations reel and stagger on their way; they make hideous mistakes; they commit frightful wrongs; they do great and beautiful things. And shall we not best guide humanity by telling the truth about all this, so far as the truth is ascertainable?”

The classroom has become a half-abandoned battlefield, where grown-ups who claim to be protecting students from the virus, from books, from ideologies and counter-ideologies end up using children to protect themselves and their own entrenched camps.

American democracy can’t afford another generation of adults who don’t know how to talk and listen and think. We owe our COVID-scarred children the means to free themselves from the failures of the past and the present.

Students are leaving as well. Since 2020, nearly 1.5 million children have been removed from public schools to attend private or charter schools or be homeschooled.

“COVID has encouraged poor parents to question the quality of public education. We are seeing diminished numbers of children in our public schools, particularly our urban public schools.” In New York, more than 80,000 children have disappeared from city schools; in Los Angeles, more than 26,000; in Chicago, more than 24,000.

I believe “Twitter poisoning” is a real thing. It is a side effect that appears when people are acting under an algorithmic system that is designed to engage them to the max. It’s a symptom of being part of a behavior-modification scheme.

The same could be said about any number of other figures, including on the left. Examples are found in the excesses of cancel culture and joyless orthodoxies in fandom, in vain attention competitions and senseless online bullying.

The human brain did not evolve to handle modern chemicals or modern media technology and is vulnerable to addiction. That is true for me and for us all.

Behavioral changes occur as a side effect of something called operant conditioning, which is the underlying mechanism of social media addiction. This is the core mechanism analogous to the role alcohol plays in alcoholism.

In the case of digital platforms, the purpose is usually “engagement,” a concept that is hard to distinguish from addiction. People receive little positive and negative jolts of social feedback — getting followed or liked, or being ignored or even humiliated.

Before social media, that kind of tight feedback loop had rarely been present in human communications outside of laboratories or marriages. (This is part of why marriage can be hard, I suspect.)  

was around when Google and other companies that operate on the personalized advertising model were created, and I can say that at least in the early days, operant conditioning was not part of the plan.

What happened was that the algorithms that optimized the individualized advertising model found their way into it automatically, unintentionally rediscovering methods that had been tested on dogs and pigeons.

There is a childish insecurity, where before there was pride. Instead of being above it all, like traditional strongmen throughout history, the modern social media-poisoned alpha male whines and frets.

What do I think are the symptoms of Twitter poisoning?

o be clear, whiners are much better than Stalins. And yet there have been plenty of more mature and gracious leaders who are better than either

When we were children, we all had to negotiate our way through the jungle of human power relationships at the playground

When we feel those old humiliations, anxieties and sadisms again as adults — over and over, because the algorithm has settled on that pattern as a powerful way to engage us — habit formation restimulates old patterns that had been dormant. We become children again, not in a positive, imaginative sense, but in a pathetic way.

Twitter poisoning makes sufferers feel more oppressed than is reasonable in response to reasonable rules. The scope of fun is constricted to transgressions.

Unfortunately, scale changes everything. Taunts become dangerous hate when amplified. A Twitter-poisoned soul will often complain of a loss of fun when someone succeeds at moderating the spew of hate.

the afflicted lose all sense of proportion about their own powers. They can come to believe they have almost supernatural abilities

The degree of narcissism becomes almost absolute. Everything is about what someone else thinks of you.

These observations should inform our concerns about TikTok. The most devastating way China might use TikTok is not to misdirect our elections or to prefer pro-China posts, but to generally ramp up social media disease, so as to make Americans more divided, less able to talk to one another and less able to put up a coordinated, unified front.

uide society. Whether that idea appeals or not, when technology degrades the minds of those same engineers, then the result can only be dysfunction.

Jaron Lanier is a computer scientist who pioneered research in virtual reality and whose books include “Ten Arguments for Deleting Your Social Media Accounts Right Now.” He is Microsoft’s “prime unifying scientist” but does not speak for the company.

The best thing it could do for society would be to implode.

Twitter hooks people in much the same way slot machines do, with what experts call an “intermittent reinforcement schedule.” Most of the time, it’s repetitive and uninteresting, but occasionally, at random intervals, some compelling nugget will appear. Unpredictable rewards, as the behavioral psychologist B.F. Skinner found with his research on rats and pigeons, are particularly good at generating compulsive behavior.

“I don’t know that Twitter engineers ever sat around and said, ‘We are creating a Skinner box,’” said Natasha Dow Schüll, a cultural anthropologist at New York University and author of a book about gambling machine design. But that, she said, is essentially what they’ve built. It’s one reason people who should know better regularly self-destruct on the site — they can’t stay away.

Twitter is not, obviously, the only social media platform with addictive qualities. But with its constant promise of breaking news, it feeds the hunger of people who work in journalism and politics, giving it a disproportionate, and largely negative, impact on those fields, and hence on our national life.

Twitter is much better at stoking tribalism than promoting progress.

According to a 2021 study, content expressing “out-group animosity” — negative feelings toward disfavored groups — is a major driver of social-media engagement

That builds on earlier research showing that on Twitter, false information, especially about politics, spreads “significantly farther, faster, deeper and more broadly than the truth.”

The company’s internal research has shown that Twitter’s algorithm amplifies right-wing accounts and news sources over left-wing ones.

This dynamic will probably intensify quite a bit if Musk takes over. Musk has said that Twitter has “a strong left bias,” and that he wants to undo permanent bans, except for spam accounts and those that explicitly call for violence. That suggests figures like Alex Jones, Steve Bannon and Marjorie Taylor Greene will be welcomed back.

But as one of the people who texted Musk pointed out, returning banned right-wingers to Twitter will be a “delicate game.” After all, the reason Twitter introduced stricter moderation in the first place was that its toxicity was bad for business

For A-list entertainers, The Washington Post reports, Twitter “is viewed as a high-risk, low-reward platform.” Plenty of non-celebrities feel the same way; I can’t count the number of interesting people who were once active on the site but aren’t anymore.

An influx of Trumpists is not going to improve the vibe. Twitter can’t be saved. Maybe, if we’re lucky, it can be destroyed.
