The essence of the Web is the linking of individual “pages” on websites, one to another. Every link represents a recommendation—a vote of interest, if not quality. So the algorithm assigns every page a rank, depending on how many other pages link to it. Furthermore, all links are not valued equally. A recommendation is worth more when it comes from a page that has a high rank itself. The math isn’t trivial—PageRank is a probability distribution, and the calculation is recursive, each page’s rank depending on the ranks of pages that depend…and so on. Page and Brin patented PageRank and published the details even before starting the company they called Google.

As they saw it from the first, their mission encompassed not just the Internet but all the world’s books and images, too.

Still, most teenagers said they read the first few sites that popped up in an online search, rather than delving further. The information often did not directly address their concerns or was densely written, they said.

When asked where they got “a lot” of health information, 55 percent of the teenagers cited their parents. School health classes and medical providers also ranked higher than the Internet as preferred sources.

teenagers do not search online the way adults do, which contributes to the uneven quality of the information they receive.

“We should be able to provide kids with better, independent online health resources.”

“Nearly one in five respondents feel financial service professionals must sometimes engage in unethical or illegal activity to be successful in the current financial environment.”

One in 10 said they had directly felt pressure “to compromise ethical standards or violate the law.”

And nearly half of the high-income earners say law enforcement and regulatory authorities in their country are ineffective “in detecting, investigating and prosecuting securities violations.”

expanded its questionnaire to more than 1,200 traders, portfolio managers, investment bankers and hedge fund professionals both in the United States and Britain

Its results appear even more noteworthy today for the sheer number of individuals who continue to say the ethics of the industry remain unchanged since the crisis (a third said that, by the way)

if one person can think he’s hooking up while the other feels she’s being raped, it makes sense to have a law that eliminates the possibility of misunderstanding. “You shouldn’t be allowed to make the assumption that if you find someone lying on a bed, they’re free for sexual pleasure,”

About a quarter of all states, and the District of Columbia, now say sex isn’t legal without positive agreement,

And though most people think of “yes means yes” as strictly for college students, it is actually poised to become the law of the land.

But criminal law is a very powerful instrument for reshaping sexual mores.

Should we really put people in jail for not doing what most people aren’t doing? (Or at least, not yet?)

It’s one thing to teach college students to talk frankly about sex and not to have it without demonstrable pre-coital assent. Colleges are entitled to uphold their own standards of comportment, even if enforcement of that behavior is spotty or indifferent to the rights of the accused. It’s another thing to make sex a crime under conditions of poor communication.

Most people just aren’t very talkative during the delicate tango that precedes sex, and the re-education required to make them more forthcoming would be a very big project. Nor are people unerringly good at decoding sexual signals. If they were, we wouldn’t have romantic comedies.

“If there’s no social consensus about what the lines are,” says Nancy Gertner, a senior lecturer at Harvard Law School and a retired judge, then affirmative consent “has no business being in the criminal law.”

The example points to a trend evident both on campuses and in courts: the criminalization of what we think of as ordinary sex and of sex previously considered unsavory but not illegal.

Some new crimes outlined in the proposed code, for example, assume consent to be meaningless under conditions of unequal power. Consensual sex between professionals (therapists, lawyers and the like) and their patients and clients, for instance, would be a fourth-degree felony, punishable by significant time in prison.

most of these occupations already have codes of professional conduct, and victims also have recourse in the civil courts. Miscreants, she says, “should be drummed out of the profession or sued for malpractice.”

It’s important to remember that people convicted of sex crimes may not only go to jail, they can wind up on a sex-offender registry, with dire and lasting consequences.

We shouldn’t forget the harm done to American communities by the national passion for incarceration, either. In a letter to the American Law Institute, Ms. Smith listed several disturbing statistics: roughly one person in 100 behind bars, one in 31 under correctional supervision

the case for affirmative consent is “compelling,” he says. Mr. Schulhofer has argued that being raped is much worse than having to endure that awkward moment when one stops to confirm that one’s partner is happy to continue. Silence or inertia, often interpreted as agreement, may actually reflect confusion, drunkenness or “frozen fright,” a documented physiological response in which a person under sexual threat is paralyzed by terror

To critics who object that millions of people are having sex without getting unqualified assent and aren’t likely to change their ways, he’d reply that millions of people drive 65 miles per hour despite a 55-mile-per-hour speed limit, but the law still saves lives. As long as “people know what the rules of the road are,” he says, “the overwhelming majority will comply with them.”

He understands that the law will have to bring a light touch to the refashioning of sexual norms, which is why the current draft of the model code suggests classifying penetration without consent as a misdemeanor, a much lesser crime than a felony.

This may all sound reasonable, but even a misdemeanor conviction goes on the record as a sexual offense and can lead to registration

An affirmative consent standard also shifts the burden of proof from the accuser to the accused, which represents a real departure from the traditions of criminal law in the United States. Affirmative consent effectively means that the accused has to show that he got the go-ahead

if the law requires a “no,” then the jury will likely perceive any uncertainty about that “no” as a weakness in the prosecution’s case and not convict. But if the law requires a “yes,” then ambiguity will bolster the prosecutor’s argument: The guy didn’t get unequivocal consent, therefore he must be guilty of rape.

“It’s an unworkable standard,” says the Harvard law professor Jeannie C. Suk. “It’s only workable if we assume it’s not going to be enforced, by and large.” But that’s worrisome too. Selectively enforced laws have a nasty history of being used to harass people deemed to be undesirable, because of their politics, race or other reasons.

it’s probably just a matter of time before “yes means yes” becomes the law in most states. Ms. Suk told me that she and her colleagues have noticed a generational divide between them and their students. As undergraduates, they’re learning affirmative consent in their mandatory sexual-respect training sessions, and they come to “believe that this really is the best way to define consent, as positive agreement,” she says. When they graduate and enter the legal profession, they’ll probably reshape the law to reflect that belief.

Sex may become safer for some, but it will be a whole lot more anxiety-producing for others.

“What he’s shown is that you do learn a great deal more by looking at the behavior that underlies the aggregates,”

Professor Deaton said he hoped “carefulness in measurement” would be his legacy. He said his mentor, Richard Stone, a Cambridge professor who won the Nobel in economics in 1984, had ingrained in him the importance of good data. “I’ve always wanted to be like him,” Professor Deaton said. “I think putting numbers together into a coherent framework always seemed to me to be what really matters.”

His work also is marked by an insistence that theories must explain these more complicated sets of facts. “A good theoretical account must explain all of the evidence that we see,” Professor Deaton wrote in a 2011 essay on his life in economics. “If it doesn’t work everywhere, we have no idea what we are talking about, and all is chaos.”

“There’s a fair amount of policy agnosticism that comes from this — it emphasizes more the heterogeneity of outcomes,” Professor Rodrik said of Professor Deaton. “He’s somebody with quite a sharp tongue, and he’s often had as his target people who make very strong statements about this policy or that policy.”

Proponents of foreign aid programs are a frequent target. Professor Deaton has argued that such investments often undermine local governance and the development of institutions necessary to sustain development.

“Life is better now than at almost any time in history,” he wrote in the opening lines of his 2013 book “The Great Escape,” a popular account of his work. “More people are richer and fewer people live in dire poverty. Lives are longer and parents no longer routinely watch a quarter of their children die.”

He counts climate change and increased economic inequality in developed nations as threats to this progress.

He has noted in other work that inequality occurs naturally because of divergent luck, but he has said that the growing gaps in recent years pose a new economic and political challenge.

“I think inequality has gone past the point where it’s helping us all get rich, and it’s really becoming a serious threat,” he said

Writing The Social Animal has been an exhilarating journey. “The scientists I’ve spent the last three years talking to are truth seekers, unlike people [in Washington]. They’re not technical materialists. They love Henry and William James. They’ve helped me see how the power of deep ideas changes the way you think. It was part of my idea to go down, down, down, to look at moral and spiritual creativity, the deepest issues. You learn the importance of culture, of history—some of the deep knowledge that comes from Plato and Aristotle. Philosophy and theology are telling us less than they used to. Scientists and researchers are leaping in where these disciplines atrophy—they’re all drilling down into an explanation of what man is.”

“I have the sense it’s a big intellectual moment. You feel the heat. It’s like Silicon Valley in the ’90s.”

Geraint Rees, director of University College London's Institute of Cognitive Neuroscience, complains that reading Tallis is "a bit like trying to nail jelly to the wall." He "rubbishes every current theory of the relationship between mind and brain, whether philosophical or neuroscientific," while offering "little or no alternative,"

cultural memes. The Darwinesque concept originates in Dawkins's 1976 book, The Selfish Gene. Memes are analogous to genes, Dennett has said, "replicating units of culture" that spread from mind to mind like a virus. Religion, chess, songs, clothing, tolerance for free speech—all have been described as memes. Tallis considers it absurd to talk of a noun-phrase like "tolerance for free speech" as a discrete entity. But Dennett argues that Tallis's objections are based on "a simplistic idea of what one might mean by a unit." Memes aren't units? Well, in that spirit, says Dennett, organisms aren't units of biology, nor are species—they're too complex, with too much variation. "He's got to allow theory to talk about entities which are not simple building blocks," Dennett says.

How is it that he perceives the glass of water on the table? How is it that he feels a sense of self over time? How is it that he can remember a patient he saw in 1973, and then cast his mind forward to his impending visit to the zoo? There are serious problems with trying to reduce such things to impulses in the brain, he argues. We can explain "how the light gets in," he says, but not "how the gaze looks out." And isn't it astonishing, he adds, that much neural activity seems to have no link to consciousness? Instead, it's associated with things like controlling automatic movements and regulating blood pressure. Sure, we need the brain for consciousness: "Chop my head off, and my IQ descends." But it's not the whole story. There is more to perceptions, memories, and beliefs than neural impulses can explain. The human sphere encompasses a "community of minds," Tallis has written, "woven out of a trillion cognitive handshakes of shared attention, within which our freedom operates and our narrated lives are led." Those views on perception and memory anchor his attack on "neurobollocks." Because if you can't get the basics right, he says, then it's premature to look to neuroscience for clues to complex things like love.

Yes, many unanswered questions persist. But these are early days, and neuroscience remains immature, says Churchland, a professor emerita of philosophy at University of California at San Diego and author of the subfield-spawning 1986 book Neurophilosophy. In the 19th century, she points out, people thought we'd never understand light. "Well, by gosh," she says, "by the time the 20th century rolls around, it turns out that light is electromagnetic radiation. ... So the fact that at a certain point in time something seems like a smooth-walled mystery that we can't get a grip on, doesn't tell us anything about whether some real smart graduate student is going to sort it out in the next 10 years or not."

Dennett claims he's got much of it sorted out already. He wrote a landmark book on the topic in 1991, Consciousness Explained. (The title "should have landed him in court, charged with breach of the Trade Descriptions Act," writes Tallis.) Dennett uses the vocabulary of computer science to explain how consciousness emerges from the huge volume of things happening in the brain all at once. We're not aware of everything, he tells me, only a "limited window." He describes that stream of consciousness as "the activities of a virtual machine which is running on the parallel hardware of the brain." "You—the fruits of all your experience, not just your genetic background, but everything you've learned and done and all your memories—what ties those all together? What makes a self?" Dennett asks. "The answer is, and has to be, the self is like a software program that organizes the activities of the brain."

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.

Rousseau wrote about “amour-propre,” a kind of self-love based on the opinions of others. He considered it unnatural and unhealthy, and believed that arbitrary social comparison led to people wasting their lives trying to look and sound attractive to others.

Narcissus falls in love not with himself, but with his reflection. In the modern version, Narcissus would fall in love with his own Instagram feed, and starve himself to death while compulsively counting his followers.

If our egos are obese with amour-propre, social media can indeed serve up the empty emotional carbs we crave. Instagram and the like doesn’t create a narcissist, but studies suggest it acts as an accelerant — a near ideal platform to facilitate what psychologists call “grandiose exhibitionism.”

No doubt you have seen this in others, and maybe even a little of it in yourself as you posted a flattering selfie — and then checked back 20 times for “likes.”

A healthy self-love that leads to true happiness is what Rousseau called “amour de soi.” It builds up one’s intrinsic well-being, as opposed to feeding shallow cravings to be admired.

First, take the Narcissistic Personality Inventory test.

Here is an individual self-improvement strategy that combines a healthy self-love (for Valentine’s Day) with a small sacrifice (possibly for Lent).

Cultivating amour de soi requires being fully alive at this moment, as opposed to being virtually alive while wondering what others think. The soulful connection with another person, the enjoyment of a beautiful hike alone (not shared on Facebook) or a prayer of thanks over your sleeping child (absent a #blessed tweet) could be considered expressions of amour de soi.

Second, get rid of the emotional junk food that is feeding any unhealthy self-obsession. Make a list of opinions to disregard — especially those of flatterers and critics — and review the list each day. Resolve not to waste a moment trying to impress others,

Third, go on a social media fast. Post to communicate, praise and learn — never to self-promote.

As for clinically significant narcissism—along with greed, invidious prejudice, and habitual lying—it is simply another one of our anti-social behaviors that mutated from our basic genetic drives…in this case the drive to survive. The opposite of narcissism is empathy, a brain-wiring that evolved much later and in parallel with our increased reliance on social interaction as a means to improve the chances of sending our genes down the line (the drive to reproduce). There is thus a certain irony in the fact that the misnamed “social” media are encouraging a decline in empathy. Your thoughts?

Sure you're not confusing narcissism with vanity? If you've ever had the misfortune of having someone with narcissistic personality disorder in your life, you would know it's about more than selfies and seeking constant approval. They are truly sick individuals that destroy the lives of those they claim to love.I would say people's addictions to social media "likes" and posting selfies is vanity

Perhaps we need to distinguish between Narcissistic Personality Disorder (NPD) and the adjective "narcissistic." We all know lots of people with way too much self-regard. NPD on the other hand ruins lives and certainly families. People who have NPD are way beyond self centered. They see the world as black and white and all people they interact with become reflections. People with NPD go to extreme lengths to control those around them and will lie, cheat and steal to do that. They are never wrong the other person is always wrong. I have worked for Narcissists and lived with one. Let's not throw around this term without defining it, please.

When participants were in diverse company, their answers were 58 percent more accurate. The prices they chose were much closer to the true values of the stocks. As they spent time interacting in diverse groups, their performance improved.In homogeneous groups, whether in the United States or in Asia, the opposite happened. When surrounded by others of the same ethnicity or race, participants were more likely to copy others, in the wrong direction. Mistakes spread as participants seemingly put undue trust in others’ answers, mindlessly imitating them. In the diverse groups, across ethnicities and locales, participants were more likely to distinguish between wrong and accurate answers. Diversity brought cognitive friction that enhanced deliberation.

For our study, we intentionally chose a situation that required analytical thinking, seemingly unaffected by ethnicity or race. We wanted to understand whether the benefits of diversity stem, as the common thinking has it, from some special perspectives or skills of minorities.

What we actually found is that these benefits can arise merely from the very presence of minorities.

before participants interacted, there were no statistically significant differences between participants in the homogeneous or diverse groups. Minority members did not bring some special knowledge.

When surrounded by people “like ourselves,” we are easily influenced, more likely to fall for wrong ideas. Diversity prompts better, critical thinking. It contributes to error detection. It keeps us from drifting toward miscalculation.

Our findings suggest that racial and ethnic diversity matter for learning, the core purpose of a university. Increasing diversity is not only a way to let the historically disadvantaged into college, but also to promote sharper thinking for everyone.

In 2014, according to the F.B.I., anti-Muslim hate crimes represented 16.3 percent of the total of 1,092 reported offenses. Anti-Semitism still led the way as a motive for hate crimes, at 58.2 percent.

Hate crimes may seem chaotic and unpredictable, a consequence of random neurons that happen to fire in the brains of a few angry young men. But we can explain some of the rise and fall of anti-Muslim hate crimes just based on what people are Googling about Muslims.

If our model is right, Islamophobia and thus anti-Muslim hate crimes are currently higher than at any time since the immediate aftermath of the Sept. 11 attacks.

How can these Google searches track Islamophobia so well? Who searches for “I hate Muslims” anyway?We often think of Google as a source from which we seek information directly, on topics like the weather, who won last night’s game or how to make apple pie. But sometimes we type our uncensored thoughts into Google, without much hope that Google will be able to help us. The search window can serve as a kind of confessional.

It is not just that hatred against Muslims is extremely high today. It’s that it’s exceptional compared with prejudice against every other group in the United States.

“If someone is willing to say ‘I hate them’ or ‘they disgust me,’ we know that those emotions are as good a predictor of behavior as actual intent,” said Susan Fiske, a social psychologist at Princeton

Google searches seem to suffer from selection bias: Instead of asking a random sample of Americans how they feel, you just get information from those who are motivated to search. But this restriction may actually help search data predict hate crimes.

“Google searches answer a different question: What do people excited enough by an issue to comment on it think and believe about it? The answer to this question, just because it is unrepresentative of the public as a whole, may be a better bet to predict hate crimes.”

While the vast majority of Muslim Americans won’t be victims of hate crimes, few escape the “constant sense of fear and paranoia” that they or their loved ones might be next, said Rana Ibrahem

What about the other side of the coin — compassion and understanding? Do they stand a chance against hate?Searches for information about Islam and Muslims did rise after the attacks in Paris and San Bernardino. Yet they rose far less than searches for hate did. “Who is Muhammad?” “what do Muslims believe?” and “what does the Quran say?” for instance, were no match for intolerance.

Google searches expressing moods, rather than looking for information, represent a tiny sample of everyone who is actually thinking those thoughts.

The search data also tells us that changes in Americans’ policy concerns have been dramatic. They happened, quite literally, within minutes of the terror attacks.Before the Paris attacks, 60 percent of Americans’ searches that took an obvious view of Syrian refugees saw them positively, asking how they could “help,” “volunteer” or “aid.” The other 40 percent were negative and mostly expressed skepticism about security. After Paris, however, the share of people opposed to refugees rose to 80 percent.

One idea might be to increase cultural integration. This is based on the “contact hypothesis”: If more Americans have Muslim neighbors, they will learn not to harbor irrational hate. We did not find support for this in the data — in fact, we found evidence for the opposite.

That’s evidence for the dominance of the “racial threat” hypothesis, which predicts that proximity breeds tension, not trust.

Another solution might be for leaders to talk about the importance of tolerance and the irrationality of hatred, as President Obama did in his Oval Office speech last Sunday night. He asked Americans to reject discrimination and religious tests for immigration. The reactions to his speech offer an excellent opportunity to see what works and what doesn’t work.

There was one line, however, that did trigger the type of response Mr. Obama might have wanted. He said, “Muslim Americans are our friends and our neighbors, our co-workers, our sports heroes and yes, they are our men and women in uniform, who are willing to die in defense of our country.”After this line, for the first time in more than a year, the top Googled noun after “Muslim” was not “terrorists,” “extremists” or “refugees.” It was “athletes,” followed by “soldiers.” And, in fact, “athletes” kept the top spot for a full day afterward.

On the whole, though, the response to the president’s speech shows that appealing to the better angels of an angry mob will most likely just backfire.

ranslates to increases in academic performance

rating themselves on a "humble-ometer," people generally did not see themselves as others see them

other team members gave better evaluations to those they viewed as humble

Then they took tests -- first individually, then with fellow group members, who gave feedback on each member's work. Students earned credit for individual and group performances

They measured "intellectual humility," based on such traits as "open to criticism" and "knows what he/she is not good at." They also measured "intellectual arrogance," based on such traits as "is close-minded" and "believes own ideas superior to others' ideas.

Additional traits also were evaluated, among them assertiveness, intelligence, self-discipline, openness and sense of humor

intellectually arrogant whom they saw as being high in dominance, extraversion and wanting to be the center of attention, but low in agreeableness and conscientiousness

But it's more challenging for groups to recognize what behavior reveals another person's humility, as opposed to simply being shy or unsure

Learning something new requires first acknowledging your own ignorance and being willing to make your ignorance known to others

Moreover, using the child-rearing questionnaire, African-Americans score as far more authoritarian than whites

what, exactly, is an “authoritarian” personality? How do you measure it?

for more than half a century — social scientists have tried to figure out why some seemingly mild-mannered people gravitate toward a strongman

the philosopher (and German refugee) Theodor Adorno collaborated with social scientists at the University of California at Berkeley to investigate why ordinary people supported fascist, anti-Semitic ideology during the war. They used a questionnaire called the F-scale (F is for fascism) and follow-up interviews to analyze the “total personality” of the “potentially antidemocratic individual.”

The resulting 1,000-page tome, “The Authoritarian Personality,” published in 1950, found that subjects who scored high on the F-scale disdained the weak and marginalized. They fixated on sexual deviance, embraced conspiracy theories and aligned themselves with domineering leaders “to serve powerful interests and so participate in their power,”

“Globalized free trade has shafted American workers and left us looking for a strong male leader, a ‘real man,’” he wrote. “Trump offers exactly what my maladapted unconscious most craves.”

one of the F-scale’s prompts: “Obedience and respect for authority are the most important virtues children should learn.” Today’s researchers often diagnose latent authoritarians through a set of questions about preferred traits in children: Would you rather your child be independent or have respect for elders? Have curiosity or good manners? Be self-reliant or obedient? Be well behaved or considerate?

a glance at the Christian group Focus on the Family’s “biblical principles for spanking” reminds us that your approach to child rearing is not pre-political; it is shorthand for your stance in the culture wars.

“All the social sciences are brought to bear to try to explain all the evil that persists in the world, even though the liberal Enlightenment worldview says that we should be able to perfect things,” said Mr. Strouse, the Trump voter

what should have been obvious:

“Trump’s electoral strength — and his staying power — have been buoyed, above all, by Americans with authoritarian inclinations,” wrote Matthew MacWilliams, a political consultant who surveyed voters during the 2016 election

The child-trait test, then, is a tool to identify white people who are anxious about their decline in status and power.

new book, “Prius or Pickup?,” by ditching the charged term “authoritarian.” Instead, they divide people into three temperamental camps: fixed (people who are wary of change and “set in their ways”), fluid (those who are more open to new experiences and people) and mixed (those who are ambivalent).

“The term ‘authoritarian’ connotes a fringe perspective, and the perspective we’re describing is far from fringe,” Mr. Weiler said. “It’s central to American public opinion, especially on cultural issues like immigration and race.”

Other scholars apply a typology based on the “Big Five” personality traits identified by psychologists in the mid-20th century: extroversion, agreeableness, conscientiousness, neuroticism and openness to experience. (It seems that liberals are open but possibly neurotic, while conservatives are more conscientious.)

Historical context matters — it shapes who we are and how we debate politics. “Reason moves slowly,” William English, a political economist at Georgetown, told me. “It’s constituted sociologically, by deep community attachments, things that change over generations.”

“it is a deep-seated aspiration of many social scientists — sometimes conscious and sometimes unconscious — to get past wishy-washy culture and belief. Discourses that can’t be scientifically reduced are problematic” for researchers who want to provide “a universal account of behavior.”

in our current environment, where polarization is so unyielding, the apparent clarity of psychological and biological explanations becomes seductive

Attitudes toward parenting vary across cultures, and for centuries African-Americans have seen the consequences of a social and political hierarchy arrayed against them, so they can hardly be expected to favor it — no matter what they think about child rearing

— we know that’s not going to happen. People have wicked tendencies.”

as the social scientific portrait of humanity grows more psychological and irrational, it comes closer and closer to approximating the old Adam of traditional Christianity: a fallen, depraved creature, unable to see himself clearly except with the aid of a higher power

The conclusions of political scientists should inspire humility rather than hubris. In the end, they have confirmed what so many observers of our species have long suspected: None of us are particularly free or rational creatures.

Allen Strouse is not the archetypal Trump voter whom journalists discover in Rust Belt diners. He is a queer Catholic poet and scholar of medieval literature who teaches at the New School in New York City. He voted for Mr. Trump “as a protest against the Democrats’ failures on economic issues,” but the psychological dimensions of his vote intrigue him. “Having studied Freudian analysis, and being in therapy for 10 years, I couldn’t not reflexively ask myself, ‘How does this decision have to do with my psychology?’” he told me.

their preoccupation with childhood and “primitive and irrational wishes and fears” have influenced the study of authoritarianism ever since.

Such work would also help address the broader question of how family interventions aimed at promoting positive developmental outcomes during childhood can benefit from focusing on relationships between siblings.

For this reason, cultures all around the world have treated emotional touching as something apart. The Greeks labeled the drive to touch with the word “eros,” and they meant something vaster and deeper than just sexual pleasure.

“Animals have sex and human beings have eros, and no accurate science is possible without making this distinction,” Allan Bloom observed.

The Abrahamic religions also treat sex as something sacred and beautiful when enveloped in loving and covenantal protections, and as something disordered and potentially peace-destroying when not.

Over the past 100 years or so, advanced thinkers across the West have worked to take the shame out of sex, surely a good thing. But they’ve also disenchanted it

“One of the principal outcomes of the sexual revolution was to establish that sex is just like any other social interaction — nothing taboo or sacred about it.” Sex is seen as a shallow physical and social thing, not a heart and soul altering thing.

One unintended effect of this disenchantment is that it becomes easy to underestimate the risks inherent in any encounter.

The woman who talked in an online article about her date with Aziz Ansari is being criticized because what happened to her was not like what happened to the victims of Harvey Weinstein and Louis C.K

The assumption seems to be that as long as there’s consent between adults, everything else is kosher.

Everything we know about touch suggests that even with full consent, the emotional quality of an encounter can have profound positive or negative effects. If Ansari did treat her coldly or neglectfully, it’s reasonable to think that the shame she felt right after was the surface effect of a deeper wound. Neglectful, dehumanizing sex is not harassment, but it’s some other form of serious harm.

Disenchanting emotional touch also causes people to underestimate the way past experiences shape current behavior.

Agency is learned, not bred. And one of the things that undermines agency most powerfully is past sexual harm.

The abuse of intimacy erodes all the building blocks of agency: self-worth, resiliency and self-efficacy (the belief that you can control a situation).

It is precisely someone who lives within a culture of supposedly zipless encounters who is most likely to be unable to take action when she feels uncomfortable.

I hate the way Babe, which published the story about the Ansari date, violated everybody’s privacy here. But it seems that the beginning of good sense is to take the power of touch seriously, as something that has profound good and bad effects.

It seems that the smarter we get about technology, the dumber we get about relationships. We live in a society in which loneliness, depression and suicide are on the rise.

The guiding moral principle here is not complicated: Try to treat other people as if they possessed precious hearts and infinite souls. Everything else will follow.

Distracted people also did not move smoothly. They took big steps sideways or dodged others in a way that the researchers rarely saw when there were no distractions. The inattentive pedestrians in the experiment induced that behavior in others as well; the people who weren’t looking at their phones moved in a more choppy fashion than they did when there were no phone-gazers.

Looking at one’s phone might have that effect because it deprives others of the information contained in our gazes, the researchers suggest.

sometimes with disastrous consequences, such as last year when a Robinhood user died by suicide after mistakenly believing that he’d lost US$750,000.

The psychological impact of game play can also be harnessed for profit.

Games also mimic rites of passage similar to religious rituals and draw players into highly focused “flow states” that dramatically alter self-awareness. This sensory blend of flow and mastery are what make games fun and sometimes addicting: “Just one more turn” thinking can last for hours, and players forget to eat and sleep. Players who barely remember yesterday’s breakfast recall visceral details from games played decades ago.

The reason games are so captivating is that they challenge the mind to learn new things and are generally safe spaces to face and overcome failure.

For example, many free-to-play video games such as Angry Birds 2 and Fortnite give players the option to spend real money on in-game items such as new and even angrier birds or character skins.

This “free-to-play” model is so profitable that it’s grown increasingly popular with video game designers and publishers.

Gamification, however, goes one step further and uses gaming elements to influence real-world behavior.

. Common elements include badges, points, rankings and progress bars that visually encourage players to achieve goals.

Many readers likely have experienced this type of gamification to improve personal fitness, get better grades, build savings accounts and even solve major scientific problems. Some initiatives also include offering rewards that can be cashed in for participating in actual civic projects, such as volunteering in a park, commenting on a piece of legislation or visiting a government website.

Sarah Everard in London. Soon Chung Park, Hyun Jung Grant, Suncha Kim, Yong Ae Yue, Delaina Ashley Yaun, Xiaojie Tan and Daoyou Feng in Atlanta.

Eight women, two continents apart, killed in the space of two weeks. The suspects in both cases are men.

London, Ms. Everard disappeared while walking home from a friend’s house, and was found dead a week later. A police officer was charged with kidnapping and murdering her.

In Atlanta, a gunman stormed three massage parlors and shot and killed eight people — seven of them women, six of them Asian — raising speculation that the attack was racially motivated

In the days after Ms. Everard’s body was found and protests calling for deeper social change grew across the United Kingdom

the British government announced an experimental pilot program (though there is no fixed start date yet) that would categorize cases of gender-based violence and harassment motivated by misogyny as hate crimes.

“Across the country, women everywhere are looking to us not just to express sympathy with their concerns, but to act,”

“Stop telling them to stay at home and be careful, and start finding those responsible for the violence.”

In Atlanta, the arrested suspect told the police he had a “sexual addiction,” according to the Cherokee County Sheriff’s Office, prompting some activists to call for him to be charged with a hate crime there, too.

“What can’t be forgotten is the hate crime statute says ‘because of gender’ as well,”

“The angle of misogyny has to be looked at.”

Do ‘sweat the small stuff’

As women around the world watched the two events unfold, they started sharing their own stories on social media of having been in similar situations that had the potential to escalate and turn similarly violent.

Women spoke of all of the things that they — like Ms. Everard — did “right,” including walking on well-lit streets, and talking on the phone or clutching their keys in their pockets while doing so — and described how they still ended up in dangerous situations.

Asian women spoke of all of the ways in which sexism and racism coalesce to expose them to a unique form of harassment that can lead to violence and abuse.

Their stories confirm that violence against women isn’t an aberration, but a “global public health” crisis of “epidemic proportions,”

In the United States, one online survey in 2018 found that 81 percent of women had experienced some kind of sexual harassment during their lifetimes. In the United Kingdom, 97 percent of women aged 18 to 24 said they had been sexually harassed, according to UN Women UK.

These numbers are all from before the coronavirus pandemic; with the onset of the health crisis, domestic abuse surged and public spaces became eerily empty, leaving women feeling increasingly worried about their safety.

Violence against women is consistently underreported because women are scared of retaliation for speaking out or they fear the stigma associated with sexual violence,

UN Women’s initiative to end gender-based violence.

“We’re not joining the dots, nobody is making connections,

“There is a big picture here that we are just repeatedly missing. There are connections between the normalized daily behaviors that we brush off and the more serious abuses.”

a woman recalls that when she was in school, at age 13 or 14, a few girls complained to a teacher that the boys in their class had been groping them and the teacher said that they were “being oversensitive.

In another example, a woman recalls waiting at a bus stop when a man walked up to her and grabbed her bottom but everyone around her who had witnessed the incident remained silent.

a woman recalls how a man sat directly opposite her on the train and touched himself and then got off the train on the next stop, as if nothing had happened.

There is plenty of evidence to suggest that misogyny and gender-based violence are also correlated with broader threats

a spike in gender-based violence — particularly domestic violence — correlates with “rising levels of insecurity in society more broadly.”

A sudden disappearance of girls from schools, for example, could point to a rise of fundamentalist views

“If only we were to listen to women and pay attention to the misogyny and aggression and violence that they deal with on a daily basis.”

As pervasive as sexism, misogyny and gender-based violence are, none are inevitable and they can be countered

“The term ‘violence against women’ is a passive construction — there’s no active agent, it’s a bad thing that happens to women,” he explained, but it’s as if “nobody’s doing it to them.”

“shifts the accountability off of men and the culture that produces them and puts it onto women.”

The second step is recognizing that male aggression against women is a manifestation of a broader systemic problem. “There’s this impulse to pathologize the individual perpetrators — that somehow the individual perpetrator is some monster who just kind of crawled out of the swamp,

“But if you accept the concept that it’s systemic, then there are policy implications and political implications and introspection that can be uncomfortable.

“And how that message plays in the community, how you talk about it, how you have police understand it.”

“Making misogyny a crime is like making racism a crime — it’s unfortunate, it’s ugly and we wish people wouldn’t do it, but you can’t punish somebody for saying something,” he said.

In other words, they’d have to show that the man assaulted her because she’s a woman, which is a tough standard to meet.

In the United States, a crime motivated by gender bias is considered a hate crime at the federal level and in 35 states.

Reporting hate crimes also requires a police force that is trained to appropriately respond to those complaints.

But that would only broaden the powers of law enforcement, which several women’s rights groups argue wouldn’t do much to prompt deeper cultural change.

. Many still felt, according to the survey, that incidents like name calling or groping seemed too normal for the police to take seriously.

“So what’s the point of me going to the police station and sitting there for two hours with a policeman who probably just thinks, ‘Why are you wasting my time?’”

But these latest shifts challenge key infection control assumptions that go back a century, putting a lot of what went wrong last year in context

They may also signal one of the most important advancements in public health during this pandemic.

If the importance of aerosol transmission had been accepted early, we would have been told from the beginning that it was much safer outdoors, where these small particles disperse more easily, as long as you avoid close, prolonged contact with others.

We would have tried to make sure indoor spaces were well ventilated, with air filtered as necessary.

Instead of blanket rules on gatherings, we would have targeted conditions that can produce superspreading events: people in poorly ventilated indoor spaces, especially if engaged over time in activities that increase aerosol production, like shouting and singing

We would have started using masks more quickly, and we would have paid more attention to their fit, too. And we would have been less obsessed with cleaning surfaces.

The implications of this were illustrated when I visited New York City in late April — my first trip there in more than a year.

A giant digital billboard greeted me at Times Square, with the message “Protecting yourself and others from Covid-19. Guidance from the World Health Organization.”

That billboard neglected the clearest epidemiological pattern of this pandemic: The vast majority of transmission has been indoors, sometimes beyond a range of three or even six feet. The superspreading events that play a major role in driving the pandemic occur overwhelmingly, if not exclusively, indoors.

The billboard had not a word about ventilation, nothing about opening windows or moving activities outdoors, where transmission has been rare and usually only during prolonged and close contact. (Ireland recently reported 0.1 percent of Covid-19 cases were traced to outdoor transmission.)

Mary-Louise McLaws, an epidemiologist at the University of New South Wales in Sydney, Australia, and a member of the W.H.O. committees that craft infection prevention and control guidance, wanted all this examined but knew the stakes made it harder to overcome the resistance. She told The Times last year, “If we started revisiting airflow, we would have to be prepared to change a lot of what we do.” She said it was a very good idea, but she added, “It will cause an enormous shudder through the infection control society.”

In contrast, if the aerosols had been considered a major form of transmission, in addition to distancing and masks, advice would have centered on ventilation and airflow, as well as time spent indoors. Small particles can accumulate in enclosed spaces, since they can remain suspended in the air and travel along air currents. This means that indoors, three or even six feet, while helpful, is not completely protective, especially over time.

To see this misunderstanding in action, look at what’s still happening throughout the world. In India, where hospitals have run out of supplemental oxygen and people are dying in the streets, money is being spent on fleets of drones to spray anti-coronavirus disinfectant in outdoor spaces. Parks, beaches and outdoor areas keep getting closed around the world. This year and last, organizers canceled outdoor events for the National Cherry Blossom Festival in Washington, D.C. Cambodian customs officials advised spraying disinfectant outside vehicles imported from India. The examples are many.

Meanwhile, many countries allowed their indoor workplaces to open but with inadequate aerosol protections. There was no attention to ventilation, installing air filters as necessary or even opening windows when possible, more to having people just distancing three or six feet, sometimes not requiring masks beyond that distance, or spending money on hard plastic barriers, which may be useless at best

clear evidence doesn’t easily overturn tradition or overcome entrenched feelings and egos. John Snow, often credited as the first scientific epidemiologist, showed that a contaminated well was responsible for a 1854 London cholera epidemic by removing the suspected pump’s handle and documenting how the cases plummeted afterward. Many other scientists and officials wouldn’t believe him for 12 years, when the link to a water source showed up again and became harder to deny.

Along the way to modern public health shaped largely by the fight over germs, a theory of transmission promoted by the influential public health figure Charles Chapin took hold

Dr. Chapin asserted in the early 1900s that respiratory diseases were most likely spread at close range by people touching bodily fluids or ejecting respiratory droplets, and did not allow for the possibility that such close-range infection could occur by inhaling small floating particles others emitted

He was also concerned that belief in airborne transmission, which he associated with miasma theories, would make people feel helpless and drop their guard against contact transmission. This was a mistake that would haunt infection control for the next century and more.

It was in this context in early 2020 that the W.H.O. and the C.D.C. asserted that SARS-CoV-2 was transmitted primarily via these heavier, short-range droplets, and provided guidance accordingly

Amid the growing evidence, in July, hundreds of scientists signed an open letter urging the public health agencies, especially the W.H.O., to address airborne transmission of the coronavirus.

Last October, the C.D.C. published updated guidance acknowledging airborne transmission, but as a secondary route under some circumstances, until it acknowledged airborne transmission as crucial on Friday. And the W.H.O. kept inching forward in its public statements, most recently a week ago.

Linsey Marr, a professor of engineering at Virginia Tech who made important contributions to our understanding of airborne virus transmission before the pandemic, pointed to two key scientific errors — rooted in a lot of history — that explain the resistance, and also opened a fascinating sociological window into how science can get it wrong and why.

Dr. Marr said that if you inhale a particle from the air, it’s an aerosol.

biomechanically, she said, nasal transmission faces obstacles, since nostrils point downward and the physics of particles that large makes it difficult for them to move up the nose. And in lab measurements, people emit far more of the easier-to-inhale aerosols than the droplets, she said, and even the smallest particles can be virus laden, sometimes more so than the larger ones, seemingly because of how and where they are produced in the respiratory tract.

Second, she said, proximity is conducive to transmission of aerosols as well because aerosols are more concentrated near the person emitting them. In a twist of history, modern scientists have been acting like those who equated stinky air with disease, by equating close contact, a measure of distance, only with the larger droplets, a mechanism of transmission, without examination.

Since aerosols also infect at close range, measures to prevent droplet transmission — masks and distancing — can help dampen transmission for airborne diseases as well. However, this oversight led medical people to circularly assume that if such measures worked at all, droplets must have played a big role in their transmission.

Another dynamic we’ve seen is something that is not unheard-of in the history of science: setting a higher standard of proof for theories that challenge conventional wisdom than for those that support it.

Another key problem is that, understandably, we find it harder to walk things back. It is easier to keep adding exceptions and justifications to a belief than to admit that a challenger has a better explanation.

The ancients believed that all celestial objects revolved around the earth in circular orbits. When it became clear that the observed behavior of the celestial objects did not fit this assumption, those astronomers produced ever-more-complex charts by adding epicycles — intersecting arcs and circles — to fit the heavens to their beliefs.

In a contemporary example of this attitude, the initial public health report on the Mount Vernon choir case said that it may have been caused by people “sitting close to one another, sharing snacks and stacking chairs at the end of the practice,” even though almost 90 percent of the people there developed symptoms of Covid-19

So much of what we have done throughout the pandemic — the excessive hygiene theater and the failure to integrate ventilation and filters into our basic advice — has greatly hampered our response.

Some of it, like the way we underused or even shut down outdoor space, isn’t that different from the 19th-century Londoners who flushed the source of their foul air into the Thames and made the cholera epidemic worse.

Righting this ship cannot be a quiet process — updating a web page here, saying the right thing there. The proclamations that we now know are wrong were so persistent and so loud for so long.

the progress we’ve made might lead to an overhaul in our understanding of many other transmissible respiratory diseases that take a terrible toll around the world each year and could easily cause other pandemics.

So big proclamations require probably even bigger proclamations to correct, or the information void, unnecessary fears and misinformation will persist, damaging the W.H.O. now and in the future.

I’ve seen our paper used in India to try to reason through aerosol transmission and the necessary mitigations. I’ve heard of people in India closing their windows after hearing that the virus is airborne, likely because they were not being told how to respond

The W.H.O. needs to address these fears and concerns, treating it as a matter of profound change, so other public health agencies and governments, as well as ordinary people, can better adjust.

It needs to begin a campaign proportional to the importance of all this, announcing, “We’ve learned more, and here’s what’s changed, and here’s how we can make sure everyone understands how important this is.” That’s what credible leadership looks like. Otherwise, if a web page is updated in the forest without the requisite fanfare, how will it matter?
