The authors specifically studied trolling — the creation of highly provocative, often false information, with the hope of spreading it widely. The report says that “many mechanisms cause false information to gain acceptance, which in turn generate false beliefs that, once adopted by an individual, are highly resistant to correction.”

in recent weeks I was the target of a trolling campaign and saw exactly how it works. It started when an obscure website published a post titled “CNN host Fareed Zakaria calls for jihad rape of white women.” The story claimed that in my “private blog” I had urged the use of American women as “sex slaves” to depopulate the white race. The post further claimed that on my Twitter account, I had written the following line: “Every death of a white person brings tears of joy to my eyes.”

Disgusting. So much so that the item would collapse from its own weightlessness, right? Wrong. Here is what happened next: Hundreds of people began linking to it, tweeting and retweeting it, and adding their comments, which are too vulgar or racist to repeat. A few ultra-right-wing websites reprinted the story as fact. With each new cycle, the levels of hysteria rose, and people started demanding that I be fired, deported or killed. For a few days, the digital intimidation veered out into the real world. Some people called my house late one night and woke up and threatened my daughters, who are 7 and 12.

The people spreading this story were not interested in the facts; they were interested in feeding prejudice. The original story was cleverly written to provide conspiracy theorists with enough ammunition to ignore evidence. It claimed that I had taken down the post after a few hours when I realized it “receive[d] negative attention.” So, when the occasional debunker would point out that there was no evidence of the post anywhere, it made little difference. When confronted with evidence that the story was utterly false, it only convinced many that there was a conspiracy and coverup.

conversations on Facebook are somewhat more civil, because people generally have to reveal their identities. But on Twitter and in other places — the online comments section of The Post, for example — people can be anonymous or have pseudonyms. And that is where bile and venom flow freely.

an experiment performed by two psychologists in 1970. They divided students into two groups based on their answers to a questionnaire: high prejudice and low prejudice. Each group was told to discuss controversial issues such as school busing and integrated housing. Then the questions were asked again. “The surveys revealed a striking pattern,” Kolbert noted. “Simply by talking to one another, the bigoted students had become more bigoted and the tolerant more tolerant.”

This “group polarization” is now taking place at hyper speed, around the world. It is how radicalization happens and extremism spreads.

Companies are sending their “policy and law folks to Washington to make the government go away — not the engineering folks who actually understand these systems in depth and can talk through alternatives,” Jonathan Mayer, an assistant professor of computer science and public affairs at Princeton University, told me.

revelations about Russian election interference and Cambridge Analytica, the voter-profiling company that obtained information on millions of Facebook users, have made it clear that data-driven influence campaigns can scale quickly and cause societal harm.

They should be examining business practices. They should be examining how these firms collect and use the personal data of customers, of internet users.”

AT&T’s privacy policy says the mobile phone and cable TV provider may use third-party data to categorize subscribers, without using their real names, into interest segments and show them ads accordingly. That sounds reasonable enough

AT&T can find out which subscribers have indigestion — or at least which ones bought over-the-counter drugs to treat it.

In a case study for advertisers, AT&T describes segmenting DirecTV subscribers who bought antacids and then targeting them with ads for the medication. The firm was also able to track those subscribers’ spending. Households who saw the antacid ads spent 725 percent more on the drugs than a national audience.

Michael Balmoris, a spokesman for AT&T, said the company’s privacy policy was “transparent and precise, and describes in plain language how we use information and the choices we give customers.”

Peterson deserves a full, appropriately complex accounting of his best and worst arguments; I intend to give him one soon. For now, I can only tell you how the Peterson phenomenon manifested one night in Aspen

“For the first time in human history the spoken word has the same reach as the written word, and there are no barriers to entry. That’s a Gutenberg revolution,” he said. “That’s a big deal. This is a game changer. The podcast world is also a Gutenberg moment but it’s even more extensive. The problem with books is that you can’t do anything else while you’re reading. But if you’re listening to a podcast you can be driving a tractor or a long haul truck or doing the dishes. So podcasts free up two hours a day for people to engage in educational activity they otherwise wouldn’t be able to engage in. That’s one-eighth of people’s lives. You’re handing people a lot of time back to engage in high-level intellectual education.

that technological revolution has revealed something good that we didn’t know before: “The narrow bandwidth of TV has made us think that we are stupider than we are. And people have a real hunger for deep intellectual dialogue.”

I’ve known for years that the university underserved the community, because we assumed that university education is for 18- to 22-year-olds, which is a proposition that’s so absurd it is absolutely mind-boggling that anyone ever conceptualized it. Why wouldn’t you take university courses throughout your entire life? What, you stop searching for wisdom when you’re 22? I don’t think so. You don’t even start until you’re like in your mid 20s. So I knew universities were underserving the broader community a long time ago. But there wasn’t a mechanism whereby that could be rectified.

Universities are beyond forgiveness, he argued, because due to the growing ranks of administrators, there’s been a radical increase in tuition. “Unsuspecting students are given free access to student loans that will cripple them through their 30s and their 40s, and the universities are enticing them to extend their carefree adolescence for a four year period at the cost of mortgaging their future in a deal that does not allow for escape through bankruptcy,” he complained. “So it’s essentially a form of indentured servitude. There’s no excuse for that … That cripples the economy because the students become overlaid with debt that they’ll never pay off at the time when they should be at the peak of their ability to take entrepreneurial risks. That’s absolutely appalling.”

A critique I frequently hear from Peterson’s critics is that everything he says is either obvious or wrong. I think that critique fails insofar as I sometimes see some critics calling one of his statements obvious even as others insist it is obviously wrong.

a reliable difference among men and women cross-culturally is that men are more aggressive than women. Now what's the evidence for that? Here's one piece of evidence: There are 10 times as many men in prison. Now is that a sociocultural construct? It's like, no, it's not a sociocultural construct. Okay?

Here's another piece of data. Women try to commit suicide more than men by a lot, and that's because women are more prone to depression and anxiety than men are. And there are reasons for that, and that's cross-cultural as well. Now men are way more likely to actually commit suicide. Why? Because they're more aggressive so they use lethal means. So now the question is how much more aggressive are men than women? The answer is not very much. So the claim that men and women are more the same than different is actually true. This is where you have to know something about statistics to understand the way the world works, instead of just applying your a priori ideological presuppositions to things that are too complex to fit in that rubric.

So if you draw two people out of a crowd, one man and one woman, and you had to lay a bet on who was more aggressive, and you bet on the woman, you'd win 40 percent of the time. That's quite a lot. It isn't 50 percent of the time which would be no differences. But it’s a lot. There are lots of women who are more aggressive than lots of men. So the curves overlap a lot. There's way more similarity than difference. And this is along the dimension where there's the most difference. But here's the problem. You can take small differences at the average of a distribution. Then the distributions move off to the side. And then all the action is at the tail. So here's the situation. You don't care about how aggressive the average person is. It's not that relevant. What people care about is who is the most aggressive person out of 100, because that's the person you'd better watch out for.

Whenever I'm interviewed by journalists who have the scent of blood in their nose, let's say, they're very willing and able to characterize the situation I find myself in as political. But that's because they can't see the world in any other manner. The political is a tiny fraction of the world. And what I'm doing isn't political. It's psychological or theological. The political element is peripheral. And if people come to the live lectures, let's say, that's absolutely self-evident

In a New York Times article titled, “Jordan Peterson, Custodian of the Patriarchy,” the writer Nellie Bowles quoted her subject as follows:

Violent attacks are what happens when men do not have partners, Mr. Peterson says, and society needs to work to make sure those men are married. “He was angry at God because women were rejecting him,” Mr. Peterson says of the Toronto killer. “The cure for that is enforced monogamy. That’s actually why monogamy emerges.” Mr. Peterson does not pause when he says this. Enforced monogamy is, to him, simply a rational solution. Otherwise women will all only go for the most high-status men, he explains, and that couldn’t make either gender happy in the end.

Ever since, some Peterson critics have claimed that Peterson wants to force women to have sex with male incels, or something similarly dystopian.

...it's an anthropological truism generated primarily through scholars on the left, just so everybody is clear about it, that societies that use monogamy as a social norm, which by the way is virtually every human society that ever existed, do that in an attempt to control the aggression that goes along with polygamy. It's like ‘Oh my God, how contentious can you get.’ Well, how many of you are in monogamous relationships? A majority. How is that enforced?...

If everyone you talk to is boring it’s not them! And so if you're rejected by the opposite sex, if you’re heterosexual, then you're wrong, they're not wrong, and you've got some work to do, man. You've got some difficult work to do. And there isn't anything I've been telling young men that's clearer than that … What I've been telling people is take the responsibility for failure onto yourself. That's a hint that you've got work to do. It could also be a hint that you're young and useless and why the hell would anybody have anything to do with you because you don't have anything to offer. And that's rectifiable. Maturity helps to rectify that.

And what's the gender? Men. Because if you go two standard deviations out from the mean on two curves that overlap but are disjointed, then you derive an overwhelming preponderance of the overrepresented group. That's why men are about 10 times more likely to be in prison.  

Weiss: You are often characterized, at least in the mainstream press, as being transphobic. If you had a student come to you and say, I was born female, I now identify as male, I want you to call me by male pronouns. Would you say yes to that?

Peterson: Well, it would depend on the student and the context and why I thought they were asking me and what I believe their demand actually characterized, and all of that. Because that can be done in a way that is genuine and acceptable, and a way that is manipulative and unacceptable. And if it was genuine and acceptable then I would have no problem with it. And if it was manipulative and unacceptable then not a chance. And you might think, ‘Well, who am I to judge?’ Well, first of all, I am a clinical psychologist, I've talked to people for about 25,000 hours. And I'm responsible for judging how I am going to use my words. I'd judge the same way I judge all my interactions with people, which is to the best of my ability, and characterized by all the errors that I'm prone to. I'm not saying that my judgment would be unerring. I live with the consequences and I'm willing to accept the responsibility.

But also to be clear about this, it never happened––I never refused to call anyone by anything they had asked me to call them by, although that's been reported multiple times. It's a complete falsehood. And it had nothing to do with the transgender issue as far as I'm concerned.

type one and type two error problem

note what his avowed position is: that he has never refused to call a transgender person by their preferred pronoun, that he has done so many times, that he would always try to err on the side of believing a request to be earnest, and that he reserves the right to decline a request he believes to be in bad faith. Whether one finds that to be reasonable or needlessly difficult, it seems irresponsible to tell trans people that a prominent intellectual hates them or is deeply antagonistic to them when the only seeming conflict is utterly hypothetical and ostensibly not even directed against people that Peterson believes to be trans, but only against people whom he does not believe to be trans

Language is an essential — perhaps the essential — marker of our species. We learn in and through natural languages; we develop our most fundamental cognitive skills by speaking and hearing languages; and we ultimately assume our identities as human beings and members of communities by exercising those languages

Our profound and impressive ability to create complex tools with which to manipulate our environments is secondary to our ability to conceptualize and communicate about those environments in natural languages.

Natural languages aren’t just more complex versions of the algorithms with which we teach machines to do tasks; they are also the living embodiments of our essence as social animals.

We express our love and our losses, explore beauty, justice and the meaning of our existence, and even come to know ourselves all though natural languages.

we are fundamentally limited in how much we can know about another’s thoughts and feelings, and that this limitation and the desire to transcend it is essential to our humanity

or us humans, communication is about much more than getting information or following instructions; it’s about learning who we are by interacting with others.

why would it be wrong for a politician to seek to connect to black audiences by sprinkling her speech with some of their dialect, which she grew up hearing and using herself? After all, language is fundamentally designed for connection. People often note that their speech tends to meld itself to the speech of those around them, such that they end up having a multilayered linguistic identity. Ocasio-Cortez has one.

Reich simply points out that this utopian fiction is in danger of collapse because it is not true and because genetic research is increasingly proving it untrue.

“You will sometimes hear that any biological differences among populations are likely to be small, because humans have diverged too recently from common ancestors for substantial differences to have arisen under the pressure of natural selection. This is not true. The ancestors of East Asians, Europeans, West Africans and Australians were, until recently, almost completely isolated from one another for 40,000 years or longer, which is more than sufficient time for the forces of evolution to work.” Which means to say that the differences could be (and actually are) substantial.

If you don’t establish a reasonable forum for debate on this, Reich argues, if you don’t establish the principle is that we do not have to be afraid of any of this, it will be monopolized by truly unreasonable and indeed dangerous racists. And those racists will have the added prestige for their followers of revealing forbidden knowledge.

so there are two arguments against the suppression of this truth and the stigmatization of its defenders: that it’s intellectually dishonest and politically counterproductive.

Klein seems to back a truly extreme position: that only the environment affects IQ scores, and genes play no part in group differences in human intelligence. To this end, he cites the “Flynn effect,” which does indeed show that IQ levels have increased over the years, and are environmentally malleable up to a point. In other words, culture, politics, and economics do matter.

But Klein does not address the crucial point that even with increases in IQ across all races over time, the racial gap is still frustratingly persistent, that, past a certain level, IQ measurements have actually begun to fall in many developed nations, and that Flynn himself acknowledges that the effect does not account for other genetic influences on intelligence.

In an email exchange with me, in which I sought clarification, Klein stopped short of denying genetic influences altogether, but argued that, given rising levels of IQ, and given how brutal the history of racism against African-Americans has been, we should nonetheless assume “right now” that genes are irrelevant.

My own brilliant conclusion: Group differences in IQ are indeed explicable through both environmental and genetic factors and we don’t yet know quite what the balance is.

We are, in this worldview, alone on the planet, born as blank slates, to be written on solely by culture. All differences between men and women are a function of this social effect; as are all differences between the races. If, in the aggregate, any differences in outcome between groups emerge, it is entirely because of oppression, patriarchy, white supremacy, etc. And it is a matter of great urgency that we use whatever power we have to combat these inequalities.

Liberalism has never promised equality of outcomes, merely equality of rights. It’s a procedural political philosophy rooted in means, not a substantive one justified by achieving certain ends.

A more nuanced understanding of race, genetics, and environment would temper this polarization, and allow for more unifying, practical efforts to improve equality of opportunity, while never guaranteeing or expecting equality of outcomes.

In some ways, this is just a replay of the broader liberal-conservative argument. Leftists tend to believe that all inequality is created; liberals tend to believe we can constantly improve the world in every generation, forever perfecting our societies.

Rightists believe that human nature is utterly unchanging; conservatives tend to see the world as less plastic than liberals, and attempts to remake it wholesale dangerous and often counterproductive.

I think the genius of the West lies in having all these strands in our politics competing with one another.

Where I do draw the line is the attempt to smear legitimate conservative ideas and serious scientific arguments as the equivalent of peddling white supremacy and bigotry. And Klein actively contributes to that stigmatization and demonization. He calls the science of this “race science” as if it were some kind of illicit and illegitimate activity, rather than simply “science.”

He goes on to equate the work of these scientists with the “most ancient justification for bigotry and racial inequality.” He even uses racism to dismiss Murray and Harris: they are, after all, “two white men.

He still refuses to believe that Murray’s views on this are perfectly within the academic mainstream in studies of intelligence, as they were in 1994.

Klein cannot seem to hold the following two thoughts in his brain at the same time: that past racism and sexism are foul, disgusting, and have wrought enormous damage and pain and that unavoidable natural differences between races and genders can still exist.

, it matters that we establish a liberalism that is immune to such genetic revelations, that can strive for equality of opportunity, and can affirm the moral and civic equality of every human being on the planet.

We may even embrace racial discrimination, as in affirmative action, that fuels deeper divides. All of which, it seems to me, is happening — and actively hampering racial progress, as the left defines the most multiracial and multicultural society in human history as simply “white supremacy” unchanged since slavery; and as the right viscerally responds by embracing increasingly racist white identity politics.

liberalism is integral to our future as a free society — and it should not falsely be made contingent on something that can be empirically disproven. It must allow for the truth of genetics to be embraced, while drawing the firmest of lines against any moral or political abuse of it

Quintarelli says that the European Union’s General Data Protection Regulation, which takes effect on May 25, following six years of preparation and debate, “can serve as guidance in some aspects.

Under the GDPR, he notes, “non-compliant organizations can face heavy fines, up to 4% of their revenues.

Had the GDPR already been in place, Facebook, in order to avoid such fines, would have had to notify the authorities of the data leak as soon as the company became aware of it, well in advance of the last U.S. election.”

the GDPR should help, because it “introduces the concept of profile portability, whereby a user can move her profile from one service provider to another, like we do when porting our telephone profile — the mobile phone number — from one operator to another.”

Just as important is “interconnection: the operator to which we port our profile should be interconnected to the source operator so that we don’t lose contact with our online friends. This is possible today thanks to technologies like IPFS and Solid, developed by the web inventor Tim Berners-Lee.”

Spiekermann, a global authority on the trafficking of our online identities for purposes of targeted advertising, political propaganda, public and private surveillance, or other nefarious purposes, emphasizes the need to crack down on “personal data markets.”

“personal data markets have thrived on the idea that personal data might be the ‘new oil’ of the digital economy as well as — so it seems — of politics.”

“more than a thousand companies are now involved in a digital information value chain that harvests data from any online activity and delivers targeted content to online or mobile users within roughly 36 seconds of their entry into the digital realm.”

then there is the mishandling of time. The physicist Lee Smolin's recent book, Time Reborn, links the crisis in physics with its failure to acknowledge the fundamental reality of time. Physics is predisposed to lose time because its mathematical gaze freezes change. Tensed time, the difference between a remembered or regretted past and an anticipated or feared future, is particularly elusive. This worried Einstein: in a famous conversation, he mourned the fact that the present tense, "now", lay "just outside of the realm of science".

Recent attempts to explain how the universe came out of nothing, which rely on questionable notions such as spontaneous fluctuations in a quantum vacuum, the notion of gravity as negative energy, and the inexplicable free gift of the laws of nature waiting in the wings for the moment of creation, reveal conceptual confusion beneath mathematical sophistication. They demonstrate the urgent need for a radical re-examination of the invisible frameworks within which scientific investigations are conducted.

we should reflect on how a scientific image of the world that relies on up to 10 dimensions of space and rests on ideas, such as fundamental particles, that have neither identity nor location, connects with our everyday experience. This should open up larger questions, such as the extent to which mathematical portraits capture the reality of our world – and what we mean by "reality".

The implied readers of his work are men who feel fatherless, solitary, floating in a chaotic moral vacuum, constantly outperformed and humiliated by women, haunted by pain and self-contempt. At some level Peterson is offering assertiveness training to men whom society is trying to turn into emasculated snowflakes.

Peterson gives them a chance to be strong. He inspires their idealism by telling them that life is hard. His worldview begins with the belief that life is essentially a series of ruthless dominance competitions.

For much of Western history, he argues, Christianity restrained the human tendency toward barbarism. But God died in the 19th century, and Christian dogma and discipline died with him

That gave us the age of ideology, the age of fascism and communism — and with it, Auschwitz, Dachau and the gulag.

Since then we’ve tried another way to pacify the race. Since most conflict is over values, we’ve decided to not have any values. We’ll celebrate relativism and tolerance

We deny the true nature of humanity and naïvely pretend everyone is nice. The upside is we haven’t blown ourselves up; the downside is we live in a world of normlessness, meaninglessness and chaos.

All of life is perched, Peterson continues, on the point between order and chaos

Chaos, the eternal feminine, is also the crushing force of sexual selection. Women are choosy maters. … Most men do not meet female human standards.”

Don’t be fooled by the naïve optimism of progressive ideology. Life is about remorseless struggle and pain. Your instinct is to whine, to play the victim, to seek vengeance.

Peterson tells young men to never do that. Rise above the culture of victimization you see all around you

“The individual must conduct his or her life in a manner that requires the rejection of immediate gratification, of natural and perverse desires alike.”

Instead, choose discipline, courage and self-sacrifice. “To stand up straight with your shoulders back is to accept the terrible responsibility of life.” Never lie. Tell your boss what you really think. Be strict with your children.

His recipe for self-improvement is solitary, nonrelational, unemotional. I’d say the lives of young men can be improved more through loving attachment than through Peterson’s joyless and graceless calls to self-sacrifice.

But the emphasis on strength of will, the bootstrap, the calls to toughness and self-respect — all of this touches some need in his audience. He doesn’t comfort

And Peterson personifies the strong, courageous virtues he champions. His most recent viral video, with over four million views, is an interview he did with Cathy Newman of Britain’s Channel 4 News.

, as Conor Friedersdorf noted in The Atlantic, she did what a lot of people do in argument these days. Instead of actually listening to Peterson, she just distorted, simplified and restated his views to make them appear offensive and cartoonish.

Peterson calmly and comprehensibly corrected and rebutted her. It is the most devastatingly one-sided media confrontation you will ever see. He reminded me of a young William F. Buckley.

The Peterson way is a harsh way, but it is an idealistic way — and for millions of young men, it turns out to be the perfect antidote to the cocktail of coddling and accusation in which they are raised

Thus, it’s incompatible with the false diversity of the college campus, which celebrates differences in sexuality and ethnicity but increasingly expects its faculty and students to think alike.

And it’s incompatible with the false inclusivity of the modern university, which all too often excludes even the most credible and serious voices if those voices challenge the orthodoxies of identity politics.

“What companies are looking for,” says Mary Jo King, the president of the National Résumé Writers’ Association, “is someone who can be all, do all, and pivot on a dime to solve any problem.”

The phenomenon is sped by automation, which usurps routine tasks, leaving employees to handle the nonroutine and unanticipated—and the continued advance of which throws the skills employers value into flux

Or, for that matter, on the relevance of the question What do you want to be when you grow up?

By 2020, a 2016 World Economic Forum report predicted, “more than one-third of the desired core skill sets of most occupations” will not have been seen as crucial to the job when the report was published

I asked John Sullivan, a prominent Silicon Valley talent adviser, why should anyone take the time to master anything at all? “You shouldn’t!” he replied.

Minimal manning—and the evolution of the economy more generally—requires a different kind of worker, with not only different acquired skills but different inherent abilities

It has implications for the nature and utility of a college education, for the path of careers, for inequality and employability—even for the generational divide.

Then, in 2001, Donald Rumsfeld arrived at the Pentagon. The new secretary of defense carried with him a briefcase full of ideas from the corporate world: downsizing, reengineering, “transformational” technologies. Almost immediately, what had been an experimental concept became an article of faith

But once cadets got into actual command environments, which tend to be fluid and full of surprises, a different picture emerged. “Psychological hardiness”—a construct that includes, among other things, a willingness to explore “multiple possible response alternatives,” a tendency to “see all experience as interesting and meaningful,” and a strong sense of self-confidence—was a better predictor of leadership ability in officers after three years in the field.

Because there really is no such thing as multitasking—just a rapid switching of attention—I began to feel overstrained, put upon, and finally irked by the impossible set of concurrent demands. Shouldn’t someone be giving me a hand here? This, Hambrick explained, meant I was hitting the limits of working memory—basically, raw processing power—which is an important aspect of “fluid intelligence” and peaks in your early 20s. This is distinct from “crystallized intelligence”—the accumulated facts and know-how on your hard drive—which peaks in your 50

Others noticed the change but continued to devote equal attention to all four tasks. Their scores fell. This group, Hambrick found, was high in “conscientiousness”—a trait that’s normally an overwhelming predictor of positive job performance. We like conscientious people because they can be trusted to show up early, double-check the math, fill the gap in the presentation, and return your car gassed up even though the tank was nowhere near empty to begin with. What struck Hambrick as counterintuitive and interesting was that conscientiousness here seemed to correlate with poor performance.

he discovered another correlation in his test: The people who did best tended to score high on “openness to new experience”—a personality trait that is normally not a major job-performance predictor and that, in certain contexts, roughly translates to “distractibility.”

To borrow the management expert Peter Drucker’s formulation, people with this trait are less focused on doing things right, and more likely to wonder whether they’re doing the right things.

High in fluid intelligence, low in experience, not terribly conscientious, open to potential distraction—this is not the classic profile of a winning job candidate. But what if it is the profile of the winning job candidate of the future?

One concerns “grit”—a mind-set, much vaunted these days in educational and professional circles, that allows people to commit tenaciously to doing one thing well

These ideas are inherently appealing; they suggest that dedication can be more important than raw talent, that the dogged and conscientious will be rewarded in the end.

he studied West Point students and graduates.

Traditional measures such as SAT scores and high-school class rank “predicted leader performance in the stable, highly regulated environment of West Point” itself.

It would be supremely ironic if the advance of the knowledge economy had the effect of devaluing knowledge. But that’s what I heard, recurrentl

“Fluid, learning-intensive environments are going to require different traits than classical business environments,” I was told by Frida Polli, a co-founder of an AI-powered hiring platform called Pymetrics. “And they’re going to be things like ability to learn quickly from mistakes, use of trial and error, and comfort with ambiguity.”

“We’re starting to see a big shift,” says Guy Halfteck, a people-analytics expert. “Employers are looking less at what you know and more and more at your hidden potential” to learn new things

advice to employers? Stop hiring people based on their work experience. Because in these environments, expertise can become an obstacle.

“The Curse of Expertise.” The more we invest in building and embellishing a system of knowledge, they found, the more averse we become to unbuilding it.

All too often experts, like the mechanic in LePine’s garage, fail to inspect their knowledge structure for signs of decay. “It just didn’t occur to him,” LePine said, “that he was repeating the same mistake over and over.

The devaluation of expertise opens up ample room for different sorts of mistakes—and sometimes creates a kind of helplessness.

Aboard littoral combat ships, the crew lacks the expertise to carry out some important tasks, and instead has to rely on civilian help

Meanwhile, the modular “plug and fight” configuration was not panning out as hoped. Converting a ship from sub-hunter to minesweeper or minesweeper to surface combatant, it turned out, was a logistical nightmare

So in 2016 the concept of interchangeability was scuttled for a “one ship, one mission” approach, in which the extra 20-plus sailors became permanent crew members

“As equipment breaks, [sailors] are required to fix it without any training,” a Defense Department Test and Evaluation employee told Congress. “Those are not my words. Those are the words of the sailors who were doing the best they could to try to accomplish the missions we gave them in testing.”

These results were, perhaps, predictable given the Navy’s initial, full-throttle approach to minimal manning—and are an object lesson on the dangers of embracing any radical concept without thinking hard enough about the downsides

a world in which mental agility and raw cognitive speed eclipse hard-won expertise is a world of greater exclusion: of older workers, slower learners, and the less socially adept.

if you keep going down this road, you end up with one really expensive ship with just a few people on it who are geniuses … That’s not a future we want to see, because you need a large enough crew to conduct multiple tasks in combat.

hat does all this mean for those of us in the workforce, and those of us planning to enter it? It would be wrong to say that the 10,000-hours-of-deliberate-practice idea doesn’t hold up at all. In some situations, it clearly does

A spinal surgery will not be performed by a brilliant dermatologist. A criminal-defense team will not be headed by a tax attorney. And in tech, the demand for specialized skills will continue to reward expertise handsomely.

But in many fields, the path to success isn’t so clear. The rules keep changing, which means that highly focused practice has a much lower return

In uncertain environments, Hambrick told me, “specialization is no longer the coin of the realm.”

It leaves us with lifelong learning,

I found myself the target of career suggestions. “You need to be a video guy, an audio guy!” the Silicon Valley talent adviser John Sullivan told me, alluding to the demise of print media

I found the prospect of starting over just plain exhausting. Building a professional identity takes a lot of resources—money, time, energy. After it’s built, we expect to reap gains from our investment, and—let’s be honest—even do a bit of coasting. Are we equipped to continually return to apprentice mode? Will this burn us out?

Everybody I met on the Giffords seemed to share that mentality. They regarded every minute on board—even during a routine transit back to port in San Diego Harbor—as a chance to learn something new.

it’s unclear whether infectious virus can persist in blood or stool

the infection can spread through the mucous membranes, from the nose down to the rectum.

while the virus appears to zero in on the lungs, it may also be able to infect cells in the gastrointestinal system, experts say. This may be why some patients have symptoms like diarrhea or indigestion

“The virus will actually land on organs like the heart, the kidney, the liver, and may cause some direct damage to those organs,

some patients in China recovered but got sick again, apparently because they had damaged and vulnerable lung tissue that was subsequently attacked by bacteria in their body.

As the body’s immune system shifts into high gear to battle the infection, the resulting inflammation may cause those organs to malfunction, he said.

About 80 percent of people infected with the new coronavirus have relatively mild symptoms. But about 20 percent of people become more seriously ill and in about 2 percent of patients in China, which has had the most cases, the disease has been fatal.

the effects appear to depend on how robust or weakened a person’s immune system is. Older people or those with underlying health issues, like diabetes or another chronic illness, are more likely to develop severe symptoms

the course a patient’s coronavirus will take is not yet fully understood.

Some patients can remain stable for over a week and then suddenly develop pneumonia, Dr. Diaz said. Some patients seem to recover but then develop symptoms again.

more than half of 121 patients in China had normal CT scans early in their disease.

Coronavirus particles have spiked proteins sticking out from their surfaces, and these spikes hook onto cell membranes, allowing the virus’s genetic material to enter the human cell.

That genetic material proceeds to “hijack the metabolism of the cell and say, in effect, ‘Don’t do your usual job. Your job now is to help me multiply and make the virus,’

As copies of the virus multiply, they burst out and infect neighboring cells. The symptoms often start in the back of the throat with a sore throat and a dry cough.

The virus then “crawls progressively down the bronchial tubes,”

That can damage the alveoli or lung sacs and they have to work harder to carry out their function of supplying oxygen to the blood

The swelling and the impaired flow of oxygen can cause those areas in the lungs to fill with fluid, pus and dead cells. Pneumonia, an infection in the lung, can occur

Some people have so much trouble breathing they need to be put on a ventilator

Dr. Krogan and his colleagues set about finding proteins in our cells that the coronavirus uses to grow. Normally, such a project might take two years. But the working group, which includes 22 laboratories, completed it in a few weeks.

In 2011, Dr. Krogan and his colleagues developed a way to find all the human proteins that viruses use to manipulate our cells — a “map,” as Dr. Krogan calls it. They created their first map for H.I.V.

That virus has 18 genes, each of which encodes a protein. The scientists eventually found that H.I.V. interacts, in one way or another, with 435 proteins in a human cell.

In February, the research group synthesized genes from the coronavirus and injected them into cells. They uncovered over 400 human proteins that the virus seems to rely on.

The flulike symptoms observed in infected people are the result of the coronavirus attacking cells in the respiratory tract.

The new map shows that the virus’s proteins travel throughout the human cell, engaging even with proteins that do not seem to have anything to do with making new viruses.

Kevan Shokat, a chemist at U.C.S.F., is poring through 20,000 drugs approved by the Food and Drug Administration for signs that they may interact with the proteins on the map created by Dr. Krogan’s lab.

If promising drugs are found, investigators plan to try them in an animal infected with the coronavirus — perhaps ferrets, because they’re known to get SARS, an illness closely related to Covid-19.

Even if some of these drugs are effective treatments, scientists will still need to make sure they are safe for treating Covid-19. It may turn out, for example, that the dose needed to clear the virus from the body might also lead to dangerous side effects.

In past studies on animals, remdesivir blocked a number of viruses. The drug works by preventing viruses from building new genes.

In February, a team of researchers found that remdesivir could eliminate the coronavirus from infected cells. Since then, five clinical trials have begun to see if the drug will be safe and effective against Covid-19 in people.

Other researchers have taken startling new approaches. On Saturday, Stanford University researchers reported using the gene-editing technology Crispr to destroy coronavirus genes in infected cells.

To have this conversation, consider saying: “If people within a group want to claim ownership of a word that has been used to hurt them, that’s their call, even if not everyone else in that group agrees with their decision. But if you’re not in the group, the word is definitely not yours to use.”

Not all girls and women believe that it is empowering to playfully refer to one another as bitches. Similarly, not all African-Americans share the same view on the use of the “N-word.” But its regular use in popular songs (mostly, but not entirely by black artists) has left a lot of kids who are not black wondering if they are free to use the word, too.

reconciliation, development and social control

thousands in the country’s Hutu ethnic majority unleashed unspeakable violence on the Tutsi minority and moderate Hutu countrymen who refused to take part in the slaughter. In just 100 days, nearly one million people perished.

Many political analysts and human rights groups say Mr. Kagame has created a nation that is orderly but repressive. Laws banning so-called genocidal ideology that were adopted to deter a resurgence of sectarian or hate speech are also used to squelch even legitimate criticism of the government.

Like others in this generation, who have been taught from their earliest school days to suppress any sense of ethnic identity, he considers himself simply Rwandan.

That was the fault of the then government that pushed us to kill Tutsis,” he said, his eyes gazing steadily ahead as he echoed a sentiment heard throughout the community from both perpetrators and survivors. “We massacred them, killed and ate their cows. I offended them gravely.”

Mr. Sendegeya re-entered society through a program that allows perpetrators to be released if they seek forgiveness from their victims.

But the healing process has taken years.

She has taught them about the history of the genocide, and she said that they knew the role that Mr. Sendegeya had played in killing members of their family, but that they had never feared him.

These results capture the stunning developmental inequalities that set in almost immediately, so that even the mental ability of 2-year-olds can be profoundly affected by the socio-economic status of their parents. As a result, their genetic potential is held back.

Such statistics have led many researchers to highlight the importance of improving the early-childhood environments of poor children.

These confessions can be explained by the field of behavioral economics, which holds that human decision-making departs frequently, significantly and predictably from what would be expected if we acted in purely “rational” ways.

Rather, our behavior is powerfully influenced by our emotions, identity and environment, as well as by how options are presented to us.

(organ donation rates are over 90 percent in countries where citizens need to override a default and opt out of donation compared with 4 to 27 percent where they much choose to opt in)

Employees were randomly assigned to one of three groups. The first was “usual care,” in which they received educational materials and free smoking cessation aids. The second was a reward program: Employees could receive up to $800 over six months if they quit. The third was a deposit program, in which smokers initially forked over $150 of their money, but if they quit, they got their deposit back along with a $650 bonus.

Those in the lottery group were eligible for a daily lottery prize with frequent small payouts and occasional large rewards — but only if they clocked in at or below their weight loss goal.

The findings suggest that a lot of the time, energy, and money poured into traditional campaigning methods is wasted, and that the campaign operatives hawking tried-and-true tactics don’t have the evidence to back up their claims.

It also casts doubt on the theory of the swing voter who can be persuaded with enough flyers, ad exposure, and conversations with earnest volunteers

In reality, Broockman and Kalla find, direct outreach is most effective at improving voter turnout, suggesting that campaigns should focus on getting their core supporters to the polls than reaching out to a mythical middle.

This new study suggests that intentionally curated, issue-specific persuasion campaigns may shift people’s views more easily than partisan political campaigns.

Emma Green: So, is political campaigning useless?Joshua Kalla: The short answer is ‘no.

There are lots of things that campaigning can accomplish. Two decades of research on voter registration and hundreds of field experiments show really cost-effective ways to increase turnout in the base.But on persuasion, yes, we find that on average, there are very small effects.

Kalla: A lot of campaign operatives think there’s this big pool of moderate, undecided voters that we can spend money on to persuade them to our side. That strategy is probably not the right strategy. And we should be skeptical of big claims of persuasion.

Kalla: All the money is being poured into the same time and the same place. It’s hard to imagine that the hundredth TV ad that a person views is really worth it from a monetary perspective, versus that same money spent in a different race or a lower race. There’s a case to be made that too much money is being spent in the same ways and on the same people.

But the takeaway from this paper should not be that campaigns should stop. Campaigns do a lot of work that is measurable in return on getting voters to vote, and persuading voters. It’s just a question of how the money is spent.

Kalla: The first order of understanding an election and how people vote is partisan identity. Most people vote based on whether there’s a D or an R next to their name. Unpacking that should be more the focus than the horserace.

We don’t see persuasive effects in general elections where a Democrat is talking to a Republican. But in ballot-measure campaigns and primaries and the transgender work, it seems that persuasion is possible.

Most Americans view themselves in a partisan lens. When it comes time to vote, it’s less a function of a person running for office than a person with a party label beside his or her name.

Green: But what about the roughly 39 percent of Americans who identify as independents?Kalla: A lot of independents tend to be what political scientists term as “closeted partisans.” They might not explicitly identify with a party, but if you ask them which party they lean toward, they’ll often give you an answer. Their behavior tends to look a lot like the behavior of people who explicitly identify as partisans.

Green: Our democracy is based on this romantic idea that encounters in the public square—conversations, essays, speeches, etc.— have the power to change how people view the world. If you’re saying that’s basically not true, where does that leave us? Are we all just destined to remain isolated in the prisons of our own convictions?

Kalla: I want to draw a distinction with the transgender canvassing work. That was very much focusing on getting people to be introspective and think about times that they or their loved ones have been discriminated against, and how that made them feel, and how that real, lived experience informs their views on non-discrimination laws and views toward LGBT people. That’s close to an ideal of how we want democracy to function.

That’s not the type of discourse you see in campaigns. I don’t think TV ads or every glossy postcard is really going to lead to enlightened discourse among the American public.

Economics teaches that incentives matter and trade-offs are unavoidable. It shows how naive attempts to fix social problems, from poverty to climate change, can have unintended consequences. Introductory economics, at its best, enables people to see the unstated assumptions and hidden costs behind the rosy promises of politicians and businessmen.

A Chilean professor, Oscar Landerretche, worked with other economists to design a new curriculum. He, Sam Bowles, of the Santa Fe Institute, Wendy Carlin, of University College London (UCL), and Margaret Stevens, of Oxford University, painstakingly knitted contributions from economists around the world into a text that is free, online and offers interactive charts and videos of star economists. That text is the basis of economics modules taught by a small but growing number of instructors.

Students pay $300 or more for textbooks explaining that in competitive markets the price of a good should fall to the cost of producing an additional unit, and unsurprisingly regurgitate the expected answers. A study of 170 economics modules taught at seven universities found that marks in exams favoured the ability to “operate a model” over proofs of independent judgment.

“The Economy”, as the book is economically titled, covers the usual subjects, but in a very different way. It begins with the biggest of big pictures, explaining how capitalism and industrialisation transformed the world, inviting students to contemplate how it arrived at where it is today.

That could mean, eventually, a broader array of perspectives within economics departments, bigger and bolder research questions—and fewer profession-shaking traumas in future.

Messy complications, from environmental damage to inequality, are placed firmly in the foreground.

It explains cost curves, as other introductory texts do, but in the context of the Industrial Revolution, thus exposing students to debates about why industrialisation kicked off when and where it did.

Thomas Malthus’s ideas are used to teach students the uses and limitations of economic models, combining technical instruction with a valuable lesson from the history of economic thought.

“The Economy” does not dumb down economics; it uses maths readily, keeping students engaged through the topicality of the material. Quite early on, students have lessons in the weirdness in economics—from game theory to power dynamics within firms—that makes the subject fascinating and useful but are skimmed over in most introductory courses.

Homa Zarghamee, also at Barnard, appreciates having to spend less time “unteaching”, ie, explaining to students why the perfect-competition result they learned does not actually hold in most cases. A student who does not finish the course will not be left with a misleading idea of economics, she notes.

But the all-important exceptions are taught quite late in the curriculum—or, often, only in more advanced courses taken by those pursuing an economics degree.

Far from an unintended result of ill-conceived policies, she argues, the roughly 4m deaths from hunger in 1932 and 1933 were part of a deliberate campaign by Josef Stalin and the Bolshevik leadership to crush Ukrainian national aspirations, literally starving actual or potential bearers of those aspirations into submission to the Soviet order

The politics in this case was the Sovietisation of Ukraine; the means was starvation. Food supply was not mismanaged by Utopian dreamers. It was weaponised.

. “Red Famine” presents a Bolshevik government so hell-bent on extracting wealth and controlling labour that it was willing to confiscate the last remaining grain from hungry peasants (mostly but not exclusively in Ukraine) and then block them from fleeing famine-afflicted areas to search for food.

. Stalin was not only aware of the ensuing mass death (amounting to roughly 13% of Ukraine’s population). He actively sought to suppress knowledge of it (including banning the publication of census data), so as not to distract from the campaign to collectivise Soviet agriculture and extend the Communist Party’s reach into the countryside—a campaign Ms Applebaum calls a “revolution...more profound and more shocking than the original Bolshevik revolution itself”

The book’s most powerful passages describe the moral degradation that resulted from sustained hunger, as family solidarity and village traditions of hospitality withered in the face of the overwhelming desire to eat. Under a state of siege by Soviet authorities, hunger-crazed peasants took to consuming, grass, animal hides, manure and occasionally each other. People became indifferent to the sight of corpses lying in streets, and eventually to their own demis

While stressing Stalin’s goal of crushing Ukrainian nationalism, moreover, Ms Applebaum passes over a subtler truth. For along with its efforts to root out “bourgeois” nationalisms, the Kremlin relentlessly promoted a Soviet version of Ukrainian identity, as it did with most other ethnic minorities. Eight decades on, that legacy has done even more to shape today’s Ukraine than the Holodomor.
