males dislike ornamented females because blue badges indicate a potentially negative quality in females. Although both sexes may develop similar ornaments because they share the genes that underlie the phenotype, expressing the ornament can be beneficial in one sex but detrimental in another.

One solution is to have the expression of [ornamentation] regulated by other factors that are already different between sexes,”

the causation and persistence of ornamentation in females” as well as “unambiguous information on fitness consequences of female ornamentation,” he continued. Because both sexes produce testosterone, added Cox, “regulation by testosterone is not a perfect mechanism for complete sex-limitation [of blue badge expression].”

detrimental ornamentation in females is a paradox that “begs the interesting question of why male-typical ornamentation persists in female fence lizards,” said Langkilde. “We plan to follow this up by examining potential benefits associated with these male-typical ornaments in females.”

Why does it happen? Some say that by mating with a “passive” male and transferring sperm, that sperm then gets passed over to the female when the passive male mates. Sneaky. But does it really happen?

If it is mistaken identity, as the authors hypothesize, it certainly happens a lot. Why could you get so many cases of false identity

In many observed cases, the males being mated with attempted to fight off the attackers. In others, they may emit pheromones of their own that let the males know that nope, this isn’t what you’re looking for. In some cases, the targeted male just runs away. But it’s hard to tell how often this happens, as no one has ever really studied it.

t very few of the hypotheses have been tested. Most of the insect orders in which male same-sex behavior has been documented have at most one or two studies. And of those, most are not focused on same-sex mating behavior; they just list it as a by-product

So it would be interesting to test these hypotheses, and to figure out what is really driving the guy-on-guy bug action. Is it pheromones? Desperation? Safety in numbers? Or something else? Science in the future will have to tell. 

since the 18th century “when people were happy to spout off about what men and women’s brains were like – before you could even look at them. They came up with these nice ideas and metaphors that fitted the status quo and society, and gave rise to different education for men and women.”

she couldn’t find any beyond the negligible, and other research was also starting to question the very existence of such differences. For example, once any differences in brain size were accounted for, “well-known” sex differences in key structures disappeared.

Are there any significant differences based on sex alone? The answer, she says, is no.

“The idea of the male brain and the female brain suggests that each is a characteristically homogenous thing and that whoever has got a male brain, say, will have the same kind of aptitudes, preferences and personalities as everyone else with that ‘type’ of brain. We now know that is not the case.

‘Forget the male and female brain; it’s a distraction, it’s inaccurate.’ It’s possibly harmful, too, because it’s used as a hook to say, well, there’s no point girls doing science because they haven’t got a science brain, or boys shouldn’t be emotional or should want to lead.”

The next question was, what then is driving the differences in behaviour between girls and boys, men and women?

“that the brain is moulded from birth onwards and continues to be moulded through to the ‘cognitive cliff’ in old age when our grey cells start disappearing.

The rules will change how the brain works and how someone behaves.” The upshot of gendered rules? “The ‘gender gap’ becomes a self-fulfilling prophecy.”

The brain is also predictive and forward-thinking in a way we had never previously realised.

the brain is much more a function of experiences. If you learn a skill your brain will change, and it will carry on changing.”

The brain is a biological organ. Sex is a biological factor. But it is not the sole factor; it intersects with so many variables.”

Letting go of age-old certainties is frightening, concedes Rippon, who is both optimistic about the future, and fearful for it.

On the plus side, our plastic brains are good learners. All we need to do is change the life lessons.

One major breakthrough in recent years has been the realisation that, even in adulthood, our brains are continually being changed, not just by the education we receive, but also by the jobs we do, the hobbies we have, the sports we play.

Once we acknowledge that our brains are plastic and mouldable, then the power of gender stereotypes becomes evident.

Beliefs about sex differences (even if ill-founded) inform stereotypes, which commonly provide just two labels – girl or boy, female or male – which, in turn, historically carry with them huge amounts of “contents assured” information and save us having to judge each individual on their own merits

With input from exciting breakthroughs in neuroscience, the neat, binary distinctiveness of these labels is being challenged – we are coming to realise that nature is inextricably entangled with nurture.

The 21st century is not just challenging the old answers – it is challenging the question itself.

What’s happening in Ferguson is the result of several recent historical factors and deeply entrenched racial attitudes, as well as a breakdown in participatory democracy.

In Ferguson, the American public has awakened to images of local police, fully decked out in surplus military gear from our recent wars in Iraq and Afghanistan, who are deploying all that in accordance with a now widespread “broken windows” policy, which was established on the hypothesis that if small crimes and misdemeanors are checked in certain neighborhoods, more serious crimes will be deterred. But this policy quickly intersected with police racial profiling already in existence to result in what has recently become evident as a propensity to shoot first.

How does this “broken windows” policy relate to the tragic deaths of young black men/boys? N.Z.:People are now stopped by the police for suspicion of misdemeanor offenses and those encounters quickly escalate.

Young black men are the convenient target of choice in the tragic intersection of the broken windows policy, the domestic effects of the war on terror and police racial profiling.

Why do you think that young black men are disproportionately targeted? N.Z.: Exactly why unarmed young black men are the target of choice, as opposed to unarmed young white women, or unarmed old black women, or even unarmed middle-aged college professors, is an expression of a long American tradition of suspicion and terrorization of members of those groups who have the lowest status in our society and have suffered the most extreme forms of oppression, for centuries.

Police in the United States are mostly white and mostly male. Some confuse their work roles with their own characters. As young males, they naturally pick out other young male opponents. They have to win, because they are the law, and they have the moral charge of protecting.

So young black males, who have less status than they do, and are already more likely to be imprisoned than young white males, are natural suspects.

Besides the police, a large segment of the white American public believes they are in danger from blacks, especially young black men, who they think want to rape young white women. This is an old piece of American mythology that has been invoked to justify crimes against black men, going back to lynching. The perceived danger of blacks becomes very intense when blacks are harmed.

The term “white privilege” is misleading. A privilege is special treatment that goes beyond a right. It’s not so much that being white confers privilege but that not being white means being without rights in many cases. Not fearing that the police will kill your child for no reason isn’t a privilege. It’s a right. 

that is what “white privilege” is meant to convey, that whites don’t have many of the worries nonwhites, especially blacks, do.

Other examples of white privilege include all of the ways that whites are unlikely to end up in prison for some of the same things blacks do, not having to worry about skin-color bias, not having to worry about being pulled over by the police while driving or stopped and frisked while walking in predominantly white neighborhoods, having more family wealth because your parents and other forebears were not subject to Jim Crow and slavery.

Probably all of the ways in which whites are better off than blacks in our society are forms of white privilege.

Over half a century later, it hasn’t changed much in the United States. Black people are still imagined to have a hyper-physicality in sports, entertainment, crime, sex, politics, and on the street. Black people are not seen as people with hearts and minds and hopes and skills but as cyphers that can stand in for anything whites themselves don’t want to be or think they can’t be.

race is through and through a social construct, previously constructed by science, now by society, including its most extreme victims. But, we cannot abandon race, because people would still discriminate and there would be no nonwhite identities from which to resist. Also, many people just don’t want to abandon race and they have a fundamental right to their beliefs. So race remains with us as something that needs to be put right.

Some of the most common types of illusory percepts are those that affect the impression of size, length or distance.

As visual processing needs to be both rapid and generally accurate, the brain constantly uses shortcuts and makes assumptions about the world that can, in some cases, be misleading.

These illusions are the result of visual processes shaped by evolution. Using that process may have been once beneficial (or still is), but it also allows our brains to be tricked.

if animals are tricked by the same illusions, then perhaps revealing why a different evolutionary path leads to the same visual process might help us understand why evolution favours this development.

Great bowerbirds could be the ultimate illusory artists. For example, their males construct forced perspective illusions to make them more attractive to mates.

When a male has two smaller clawed males on either side of him he is more attractive to a female (because he looks relatively larger) than if he was surrounded by two larger clawed males.

This effect is known as the Ebbinghaus illusion (see image), and suggests that males may easily manipulate their perceived attractiveness by surrounding themselves with less attractive rivals.

Deceptions of the senses are the truths of perception.

Visual illusions (and those in the non-visual senses) are a crucial tool for determining what perceptual assumptions animals make about the world around them.

What the research has found is that the brains of trans people are unique: neither female nor male, exactly, but something distinct.

But what does that mean, a male brain, or a female brain, or even a transgender one?

It’s a fraught topic, because brains are a collection of characteristics, rather than a binary classification of either/or

yet scientists continue to study the brain in hopes of understanding whether a sense of the gendered self can, at least in part, be the result of neurology

Well, not entirely. Because not every person with a Y chromosome is male, and not every person with a double X is female. The world is full of people with other combinations: XXY (or Klinefelter Syndrome), XXX (or Trisomy X), XXXY, and so on. There’s even something called Androgen Insensitivity Syndrome, a condition that keeps the brains of people with a Y from absorbing the information in that chromosome. Most of these people develop as female, and may not even know about their condition until puberty — or even later.

t there’s a problem with using neurology as an argument for trans acceptance — it suggests that, on some level, there is something wrong with transgender people, that we are who we are as a result of a sickness or a biological hiccup.

trying to open people’s hearts by saying “Check out my brain!” can do more harm than good, because this line of argument delegitimizes the experiences of many trans folks. It suggests that there’s only one way to be trans — to feel trapped in the wrong body, to go through transition, and to wind up, when all is said and done, on the opposite-gender pole. It suggests that the quest trans people go on can only be considered successful if it ends with fitting into the very society that rejected us in the first place.

All the science tells us, in the end, is that a biological male — or female — is not any one thing, but a collection of possibilities.

No one who embarks upon a life as a trans person in this country is doing so out of caprice, or a whim, or a delusion. We are living these wondrous and perilous lives for one reason only — because our hearts demand it.

what we need now is not new legislation to make things harder. What we need now is understanding, not cruelty. What we need now is not hatred, but love.

the important thing is not that they feel like a woman, or a man, or something else. What matters most is the plaintive desire, to be free to feel the way I feel.

The researchers used facial-recognition software to map out specific points on a person’s face, then applied machine-learning algorithms to the facial points to obtain empirical measures for three key face impressions—trustworthiness, dominance and attractiveness.  

They examined the association of these impressions with the accuracy of analysts’ quarterly forecasts, drawn from the Institutional Brokers Estimate System

. Under most circumstances, such quick impressions aren’t accurate and shouldn’t be trusted, he says.

For an average stock valued at $100, Prof. Teoh says, analysts ranked as looking most trustworthy were 25 cents more accurate in earnings-per-share forecasts than the analysts who were ranked as looking least trustworthy

Similarly, most-dominant-looking analysts were 52 cents more accurate in their EPS forecast than least-dominant-looking analysts.

The relation between a dominant face and accuracy, meanwhile, was significant before and after the regulation was enacted, the analysts say. This suggests that dominant-looking male analysts are always able to obtain information,

While forecasts of female analysts regardless of facial characteristics were on average more accurate than those of their male counterparts, the forecasts of women who were seen as more-dominant-looking were significantly less accurate than their male counterparts.  

Says Prof. Todorov: “Women who look dominant are more likely to be viewed negatively because it goes against the cultural stereotype.

At sea or in the wilderness, these friends managed to escape both from the institutions of patriarchy and from the intimate authority of women, the mothers and wives who represent a check on male freedom.

What all of these shows grasp at, in one way or another, is that nobody knows how to be a grown-up anymore. Adulthood as we have known it has become conceptually untenable.

From the start, American culture was notably resistant to the claims of parental authority and the imperatives of adulthood. Surveying the canon of American literature in his magisterial “Love and Death in the American Novel,” Leslie A. Fiedler suggested, more than half a century before Ruth Graham, that “the great works of American fiction are notoriously at home in the children’s section of the library.”

“The typical male protagonist of our fiction has been a man on the run, harried into the forest and out to sea, down the river or into combat — anywhere to avoid ‘civilization,’ which is to say the confrontation of a man and woman which leads to the fall to sex, marriage and responsibility. One of the factors that determine theme and form in our great books is this strategy of evasion, this retreat to nature and childhood which makes our literature (and life!) so charmingly and infuriatingly ‘boyish.’ ”

What Fiedler notes, and what most readers of “Huckleberry Finn” will recognize, is Twain’s continual juxtaposition of Huck’s innocence and instinctual decency with the corruption and hypocrisy of the adult world.

we’ve also witnessed the erosion of traditional adulthood in any form, at least as it used to be portrayed in the formerly tried-and-true genres of the urban cop show, the living-room or workplace sitcom and the prime-time soap opera. Instead, we are now in the age of “Girls,” “Broad City,” “Masters of Sex” (a prehistory of the end of patriarchy), “Bob’s Burgers” (a loopy post-"Simpsons” family cartoon) and a flood of goofy, sweet, self-indulgent and obnoxious improv-based web videos.

we have a literature of boys’ adventures and female sentimentality. Or, to put it another way, all American fiction is young-adult fiction.

The bad boys of rock ‘n’ roll and the pouting screen rebels played by James Dean and Marlon Brando proved Fiedler’s point even as he was making it. So did Holden Caulfield, Dean Moriarty, Augie March and Rabbit Angstrom — a new crop of semi-antiheroes

We devolve from Lenny Bruce to Adam Sandler, from “Catch-22” to “The Hangover,” from “Goodbye, Columbus” to “The Forty-Year-Old Virgin.”

Unlike the antiheroes of eras past, whose rebellion still accepted the fact of adulthood as its premise, the man-boys simply refused to grow up, and did so proudly. Their importation of adolescent and preadolescent attitudes into the fields of adult endeavor (see “Billy Madison,” “Knocked Up,” “Step Brothers,” “Dodgeball”) delivered a bracing jolt of subversion, at least on first viewing. Why should they listen to uptight bosses, stuck-up rich guys and other readily available symbols of settled male authority?

That was only half the story, though. As before, the rebellious animus of the disaffected man-child was directed not just against male authority but also against women. I

their refusal of maturity also invites some critical reflection about just what adulthood is supposed to mean. In the old, classic comedies of the studio era — the screwbally roller coasters of marriage and remarriage, with their dizzying verbiage and sly innuendo — adulthood was a fact. It was inconvertible and burdensome but also full of opportunity. You could drink, smoke, flirt and spend money.

The desire of the modern comic protagonist, meanwhile, is to wallow in his own immaturity, plumbing its depths and reveling in its pleasures.

Last words such as these are only found in 14% of cases. The authors began to notice differences between note leavers and non-leavers in their research, as well as people who attempt suicide and those who complete the act.

Many notes were addressed to one person. Others were to no one in particular.

Nowadays, being a white male is the single biggest risk factor. Why is that? According to Case and Deaton, drastic changes in the labor market is the most significant factor.

“Hegemonic masculinity,” or a perception that heightened masculinity must be portrayed at all times, a goal that no male can live up to.

Another 23% of note writers ended it all due to unrequited love or love lost. 22% said they themselves created the problem which led to their decision.

Meyer and colleagues also propose a national prevention plan, to foster a sense of community and social support.

If you feel suicidal, or are concerned for a friend, don't wait: talk to someone, or learn about suicide prevention here.

this might explain why it is relative, rather than absolute, inequality that matters so much to people today. In modern Western society, when even relatively poor people have access to transport, refrigeration, entertainment, shoes and plentiful food, you might expect that inequality would be less resented than a century ago—when none of those things might come within the reach of a poor person. What does it matter if there are people who can afford private jets and designer dresses? But clearly that isn't how people think. They resent inequality in luxuries just as much if not more than inequality in necessities. They dislike (and envy) conspicuous consumption, even if it impinges on them not at all. What hurts is not that somebody is rich, but that he is richer.

It’s not that young women aren’t feminists, or don’t care about sexism. For college-age women — Mr. Sanders’s female base — sexism tends to be linked to sex.

Young women are neither ungrateful to their feminist foremothers nor complacent; rather, they are activists for feminist causes that reflect their needs.

College-educated women see only a tiny pay gap in their early- and mid-20s, making 97 cents for every dollar earned by their male colleagues.

That experience starts to change a few more years into the work force. By 35, those same college-educated women are making 15 percent less than their male peers. Women’s earnings peak between ages 35 and 44 and then plateau, while men’s continue to rise.

When women have children, they’re penalized: They’re considered less competent, they’re less likely to be hired for a new job and they’re paid less

one of the few female partners always seemed to be in charge of ordering lunch

For the many women who live at the center of that time crush, Mrs. Clinton’s emphasis on the wage gap, paid family leave and universal prekindergarten may be particularly appealing. Mr. Sanders, who also supports paid leave and universal pre-K, takes a different rhetorical tone, usually stressing affordable higher education and universal health care.

I watched as men with little or irrelevant experience were hired and promoted, because they had such great ideas, or they fit in better. “We want a woman,” the conclusion seemed to be, “just not this woman.”

in the now-common refrain about Hillary Clinton: “I want a woman president, just not this woman president.”

a 19-year-old aspiring lawyer who is volunteering for Mr. Sanders today will work for firms with more female partners and live in a world where the wage gap has shrunk. But the trends show that her experience in a decade is unlikely to be that different from mine.

Many more women over 25 are in the work force than those under, and women over 25 also do about twice as much unpaid domestic work as their younger counterparts.

I listened as some of my male colleagues opined on the need to marry a woman who would stay home with the children — that wasn’t sexist, they insisted, because it wasn’t that they thought only women should stay home; it was just that somebody had to, and the years in which they planned on having children would be crucial ones for their own careers.

Child care is just as expensive in many places as sending a kid to public university, but a college kid can get a part-time job. A toddler can’t.”

There are many other reasons women in the 30-and-over cohort may lean toward Mrs. Clinton. They’ve already seen promises of revolutionary change fall short. They may prefer a candidate with a progressive ideology but a more restrained, and potentially more effective, strategy for putting that ideology in place.

If it’s not this woman, this year, then who and when?

“The most important thing when you study hypnosis is that you learn that humans are irrational,

what Trump is doing? He is acknowledging the suffering of some, Adams says, and then appealing emotionally to that.

2. Knowing that people are irrational, Trump aims to appeal on an emotional level.

Having nothing to lose essentially then increases his chance of winning, because it opens up his field of rhetorical play.

Within that context, here is what Candidate Trump is doing to win campaign hearts and minds

1. Trump knows people are basically irrational.

he bolsters that approach, Adams says, by “exploiting the business model” like an entrepreneur. In this model, which “the news industry doesn’t have the ability to change … the media doesn’t really have the option of ignoring the most interesting story,” says Adams, contending that Trump “can always be the most interesting story if he has nothing to fear and nothing to lose.”

“The evidence is that Trump completely ignores reality and rational thinking in favor of emotional appeal,” Adams writes. “Sure, much of what Trump says makes sense to his supporters, but I assure you that is coincidence. Trump says whatever gets him the result he wants. He understands humans as 90-percent irrational and acts accordingly.”

3. By running on emotion, facts don’t matter.

“There are plenty of important facts Trump does not know. But the reason he doesn’t know those facts is – in part – because he knows facts don’t matter. They never have and they never will. So he ignores them.

4. If facts don’t matter, you can’t really be “wrong.”

“If you understand persuasion, Trump is pitch-perfect most of the time. He ignores unnecessary rational thought and objective data and incessantly hammers on what matters (emotions).”

“Did Trump’s involvement in the birther thing confuse you?” Adams goes on to ask. “Were you wondering how Trump could believe Obama was not a citizen? The answer is that Trump never believed anything about Obama’s place of birth. The facts were irrelevant, so he ignored them while finding a place in the hearts of conservatives.

5. With fewer facts in play, it’s easier to bend reality.

Among the persuasive techniques that Trump uses to help bend reality, Adams says, are repetition of phrases; “thinking past the sale” so the initial part of his premise is stated as a given; and knowing the appeal of the simplest answer, which relates to the concept of Occam’s razor.

6. To bend reality, Trump is a master of identity politics — and identity is the strongest persuader.

“The best Trump linguistic kill shots,” Adams writes,”have the following qualities: 1. Fresh word that is not generally used in politics; 2. Relates to the physicality of the subject (so you are always reminded).”

: “Identity is always the strongest level of persuasion. The only way to beat it is with dirty tricks or a stronger identity play. … [And] Trump is well on his way to owning the identities of American, Alpha Males, and Women Who Like Alpha Males. Clinton is well on her way to owning the identities of angry women, beta males, immigrants, and disenfranchised minorities.

Professors were more responsive to white male students than to female, black, Hispanic, Indian or Chinese students in almost every discipline and across all types of universities

We found the most severe bias in disciplines paying higher faculty salaries and at private universities

our own discipline of business showed the most bias, with 87 percent of white males receiving a response compared with just 62 percent of all females and minorities combined.

We computed the average response rates for each category of student (e.g., white male, Hispanic female), dividing the number of responses from the professors by the number of emails sent from students in a given race or gender category.

Were Asians favored, given the model minority stereotype they supposedly benefit from in academic contexts? No. In fact, Chinese students were the most discriminated-against group in our sample

Did reaching out to someone of the same gender or race — such as a black student emailing a black professor — reduce bias? No. We saw the same levels of bias in both same-race and same-gender faculty-student pairs that we saw in pairs not sharing a race or gender (the one exception was Chinese students writing to Chinese professors).

Did it help to be in a discipline with a greater representation of women and minorities? Again, no. Faculty members in those more diverse disciplines, like criminal justice, were no less likely to discriminate than those in less diverse disciplines,

Did it help that these were students in the pre-applicant stage, when some believe underrepresented groups enjoy advantageous access to selective opportunities? Again, no

each of the supposed hidden advantages of being a woman or minority proved to be no more than a phantom.

Suspecting that powerful women stayed quiet because they feared a backlash, Professor Brescoll looked deeper.

Male executives who spoke more often than their peers were rewarded with 10 percent higher ratings of competence.

female executives spoke more than their peers, both men and women punished them with 14 percent lower ratings.

But female employees who spoke up with equally valuable ideas did not improve their managers’ perception of their performance.

But when women spoke up more, there was no increase in their perceived helpfulness.

businesses need to find ways to interrupt this gender bias.

increase women’s contributions by adopting practices that focus less on the speaker and more on the idea

SINCE most work cannot be done anonymously, leaders must also take steps to encourage women to speak and be heard

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

t is true that race is a social construct. It is also true, as Dr. Lewontin wrote, that human populations “are remarkably similar to each other” from a genetic point of view.

this consensus has morphed, seemingly without questioning, into an orthodoxy. The orthodoxy maintains that the average genetic differences among people grouped according to today’s racial terms are so trivial when it comes to any meaningful biological traits that those differences can be ignored.

With the help of these tools, we are learning that while race may be a social construct, differences in genetic ancestry that happen to correlate to many of today’s racial constructs are real.

I have deep sympathy for the concern that genetic discoveries could be misused to justify racism. But as a geneticist I also know that it is simply no longer possible to ignore average genetic differences among “races.”

Groundbreaking advances in DNA sequencing technology have been made over the last two decades

Care.

The orthodoxy goes further, holding that we should be anxious about any research into genetic differences among populations

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

I am worried that well-meaning people who deny the possibility of substantial biological differences among human populations are digging themselves into an indefensible position, one that will not survive the onslaught of science.

I am also worried that whatever discoveries are made — and we truly have no idea yet what they will be — will be cited as “scientific proof” that racist prejudices and agendas have been correct all along, and that those well-meaning people will not understand the science well enough to push back against these claims.

This is why it is important, even urgent, that we develop a candid and scientifically up-to-date way of discussing any such difference

While most people will agree that finding a genetic explanation for an elevated rate of disease is important, they often draw the line there. Finding genetic influences on a propensity for disease is one thing, they argue, but looking for such influences on behavior and cognition is another

Is performance on an intelligence test or the number of years of school a person attends shaped by the way a person is brought up? Of course. But does it measure something having to do with some aspect of behavior or cognition? Almost certainly.

Recent genetic studies have demonstrated differences across populations not just in the genetic determinants of simple traits such as skin color, but also in more complex traits like bodily dimensions and susceptibility to diseases.

in Iceland, there has been measurable genetic selection against the genetic variations that predict more years of education in that population just within the last century.

consider what kinds of voices are filling the void that our silence is creating

Nicholas Wade, a longtime science journalist for The New York Times, rightly notes in his 2014 book, “A Troublesome Inheritance: Genes, Race and Human History,” that modern research is challenging our thinking about the nature of human population differences. But he goes on to make the unfounded and irresponsible claim that this research is suggesting that genetic factors explain traditional stereotypes.

139 geneticists (including myself) pointed out in a letter to The New York Times about Mr. Wade’s book, there is no genetic evidence to back up any of the racist stereotypes he promotes.

Another high-profile example is James Watson, the scientist who in 1953 co-discovered the structure of DNA, and who was forced to retire as head of the Cold Spring Harbor Laboratories in 2007 after he stated in an interview — without any scientific evidence — that research has suggested that genetic factors contribute to lower intelligence in Africans than in Europeans.

What makes Dr. Watson’s and Mr. Wade’s statements so insidious is that they start with the accurate observation that many academics are implausibly denying the possibility of average genetic differences among human populations, and then end with a claim — backed by no evidence — that they know what those differences are and that they correspond to racist stereotypes

They use the reluctance of the academic community to openly discuss these fraught issues to provide rhetorical cover for hateful ideas and old racist canards.

This is why knowledgeable scientists must speak out. If we abstain from laying out a rational framework for discussing differences among populations, we risk losing the trust of the public and we actively contribute to the distrust of expertise that is now so prevalent.

If scientists can be confident of anything, it is that whatever we currently believe about the genetic nature of differences among populations is most likely wrong.

For example, my laboratory discovered in 2016, based on our sequencing of ancient human genomes, that “whites” are not derived from a population that existed from time immemorial, as some people believe. Instead, “whites” represent a mixture of four ancient populations that lived 10,000 years ago and were each as different from one another as Europeans and East Asians are today.

For me, a natural response to the challenge is to learn from the example of the biological differences that exist between males and females

The differences between the sexes are far more profound than those that exist among human populations, reflecting more than 100 million years of evolution and adaptation. Males and females differ by huge tracts of genetic material

How do we accommodate the biological differences between men and women? I think the answer is obvious: We should both recognize that genetic differences between males and females exist and we should accord each sex the same freedoms and opportunities regardless of those differences

fulfilling these aspirations in practice is a challenge. Yet conceptually it is straightforward.

Compared with the enormous differences that exist among individuals, differences among populations are on average many times smaller, so it should be only a modest challenge to accommodate a reality in which the average genetic contributions to human traits differ.

The Australopithecines, the relatively small-brained, bipedal ancestors of our genus that lived in Africa somewhere between 1 million and 4 million years ago, probably threw projectiles as well, since their hand bones hint at their ability to grip objects and throw them.

Once the ability to throw quickly and accurately became critical to success in combat and hunting, our male ancestors would have been more likely than females to develop, through natural selection, these skills, since anthropologists have shown that males tended to fight and hunt big game.

Sex differences in throwing do not exist just because males are, on average, larger and stronger. The relative size, shape and orientation of the shoulders of men increase the range of motion of the arm during the cocking phase, which facilitates better throwing.

The countries where students were guilty of the most BS? The U.S. and Canada. Students in the two counties had scores that were .25 and .3 above average on the study’s “bullshit scale.” However, the two counties also had the narrowest gap between boys and girls, with a gap of .25 and .34 between the genders. In England and Ireland, the gap was much wider – .48 and .46 points.

Shure says that she is interested in determining whether a person’s ability to BS has a major impact on economic inequality between men and women, and how the ability plays out across socioeconomic lines.

“You can imagine that the people that score high on this bullshit index are good at certain things that might be rewarded,” says Shure. “It might be an interview to get into college. It could be an interview for a job, or an internship. It could be those skills end up helping exacerbate the gap that we observe between people from rich backgrounds and poor backgrounds, and even men and women.”

However, Shure says that it’s conceivable that “bullshitters” may have an advantage when it comes to getting ahead: “They clearly have very high opinions of themselves. And that could be associated with becoming leaders in the future.”

For those of us seeking to appear friendly and trustworthy to others, a new study underscores an old, chipper piece of advice: Put on a happy face.

the relevance of facial expressions to perceptions of characteristics such as trustworthiness and friendliness.

for those faces lacking structural cues, people could no longer perceive strength but could still perceive personality traits based on facial expressions.

An analysis revealed that participants generally ranked people with a happy expression as friendly and trustworthy but not those with angry expressions.

rank faces as indicative of physical strength based on facial expression but graded faces that were very broad as that of a strong individual.

In the first variation, for faces lacking emotional cues, people could no longer perceive personality traits but could still perceive strength based on width

perceptions of abilities such as physical strength are not dependent on facial expressions but rather on facial bone structure.

As might be expected, participants picked faces with happier expressions as financial advisors and selected broader faces as belonging to power-lifting champs.

Most of the participants found the computer-generated averages to be good representations of trustworthiness or strength — and generally saw the average “financial advisor” face as more trustworthy and the “power-lifter” face as stronger.

he findings suggest facial expressions strongly influence perception of traits such as trustworthiness, friendliness or warmth, but not ability (strength, in these experiments).

facial structure influences the perception of physical ability but not intentions (such as friendliness and trustworthiness, in this instance)

this new work reveals how perceptions of the same person can vary greatly depending on that person’s facial expression in any given moment

The findings above come with a big caveat: Only male faces were shown to subjects.

Studies of facial width and height in females have shown mixed results, so presenting study subjects with a mix of male and female faces would have yielded inconclusive results.

In our everyday lives this study and others make clear that although we might try to influence others’ perceptions of us with photos showing us donning sharp attire or displaying a self-assured attitude, the most important determinant of others' perception of and consequent behavior toward us is our faces.
