"Why should any individual woman today be advantaged over any individual man just because other men were advantaged over other women in the past? Reversing historical injustices does not erase them; it merely adds to the total number of injustices in the world. The question we face today, therefore, is this: Is the appropriate response to injustice to try to eliminate it, or to turn it on its head?"

"[T]he evidence for discrimination in STEM is considerably more mixed than is often assumed. Certainly, many studies have found evidence of anti-female discrimination in STEM. At the same time, however, many other studies have failed to find such discrimination, or have found discrimination in favour of women."

"As memetic evolution picked up steam, humans were transformed. No longer were we devices designed solely to pass on our genes. Suddenly, we became hybrid creatures, torn between passing on our genes and passing on our memes. This vision of our species helps to explain much of what most puzzled the alien scientist: our moral systems, our religions, our art and music and science. Cultural evolution is the key to unravelling the deepest mysteries of the human animal."

"[O]ne of the main moral foundations of the women’s liberation movement – and indeed of all liberation movements – is the idea that individuals should be treated fairly and equally, and that unjust barriers should be removed. A policy that advantages members of one demographic group over those of another necessarily abandons those principles. In doing so, it risks leaving the women’s movement without one of its main moral foundations."

"[I]t is widely accepted these days that people should be treated fairly and respectfully regardless of whether they buck the trend for their sex, and no ethical theory we’re familiar with implies that this is only the case if the trend in question is 100% environmental in origin."

"Real-world data going back to the 1980s suggest that, although fewer women apply for jobs in fields such as maths, physics, chemistry, biology, and engineering, those who do apply are no less likely to be interviewed and no less likely to be offered the job. On the contrary, they are generally more likely to be."

"This is the irritating reality of the human condition: Whatever we do, we’re left with unfulfilled desires. Human beings are chronically conflicted animals. And that’s because that’s what selection made us."

"Rather than the human brain evolving for God, God evolved for the human brain."

"First, the claim is not that men perform better than women in every cognitive domain. On the contrary, men perform better in some domains whereas women perform better in others. The best-known examples are that men score higher than women on most tests of spatial ability, whereas women score higher than men on most tests of language ability, including verbal comprehension, reading, and writing... Second, even in areas where men do perform better, the claim is not that all men – or even most – perform better than all or most women. As with occupational preferences, members of both sexes vary enormously in every cognitive aptitude, and the distribution for men overlaps almost entirely with that for women. However, for some aptitudes, the distribution for one sex is shifted somewhat to the right of that for the other, such that the average score for the former is somewhat higher. In saying this, it’s worth stressing that the average score does not describe all members of the group, or even the typical member, but merely represents the central tendency within a broad array of scores. Most people fall above or below the average. Third, the claim is not that these cognitive sex differences are especially large. On the contrary, at the centre of the distribution, they tend to be quite small. The only reason they matter at all is that even small differences at the mean are associated with progressively larger differences the further from the mean one looks... Fourth, the claim is not that women lack the cognitive talents to make it in STEM. Most people lack the cognitive talents, and of those who do possess them, some are men and some are women."

"Several studies have concluded that tests of implicit bias (in particular, the Implicit Association Test or IAT) have poor test-retest reliability, and fail to predict discriminatory behaviour. Furthermore, though interventions may change people’s implicit biases to some degree – or do so, at least, in the short-term – the effects of such changes on behaviour are trivially small or non-existent, even in the immediate wake of the intervention."

"[T]he strong emphasis on increasing the numbers of women in male-dominated fields is arguably somewhat sexist. As Susan Pinker argues, it tacitly assumes that women do not know what they want, or that they want the wrong things and thus that wiser third-parties need to “fix” their existing preferences. It also tacitly assumes that the areas where men dominate are superior."

"Sex differences in various psychological traits – in particular, average differences in career-related interests – contribute more to STEM gender gaps than is often assumed. These differences are not due solely to learning, but have a biological component as well... Certainly, the evidence for a biological contribution is not beyond criticism. We suggest, however, that the totality of the evidence renders the Nurture-Only view considerably less plausible than the Nature-Plus-Nurture alternative. The evidence we find most compelling includes the stubbornness of the sex differences over time, even despite efforts to eradicate them; the cross-cultural consistency of the differences; the early appearance of some differences during development; evidence linking the traits in question to prenatal hormonal exposure; and in some cases, comparable differences in evolutionarily relevant nonhuman animals. Each of these findings would be more surprising if the relevant sex differences were due solely to culture than if biology were also involved. And although alternative explanations for any particular finding are always possible, the convergence of these very different lines of evidence adds up to a strong prima facie case for a non-trivial biological contribution."

"[W]e should strive to eliminate bias and barriers of every kind... What we would argue, though, is that even if this were achieved, STEM gender gaps would be unlikely to disappear given persistent sex differences in interests and other STEM-relevant traits – differences plausibly due in part to biological causes. The question, then, is: Would this necessarily be a problem? In our view, as long as unjust impediments are removed, and everyone is invited, it would not be. On the contrary, it would be unfortunate if, for all the talk of celebrating differences and diversity, we ultimately came to insist that justice requires sameness."

"[I]t is not only men who may be harmed by preferences and quotas. In a number of ways, women could be harmed as well. To begin with, such policies could cast a shadow of doubt over women’s genuine accomplishments."

"As far as we know, no woman in the history of the species has ever given birth and thought: “Wait a minute! How do I know that this baby is mine and not some other woman’s?” In contrast, if a baby comes out of the body of a woman you slept with nine months ago, that’s not nearly as reliable a clue. As an old saying has it, maternity is a matter of fact, paternity a matter of opinion."

"Jane Goodall once wrote about a female chimpanzee who mated with more than fifty males in a single day. This is uncommon among human beings, even in LA."

"Humans are chimpanzees reciting Shakespeare – dunces with the technology of geniuses."

"During the heyday of European colonialism, a number of indigenous groups came to the view that, if they had faith, the Europeans’ bullets couldn’t harm them. Needless to say, this meme had disastrous consequences. One group infected with the meme – the Mahdists of Sudan – lost 11,000 men in a single battle to the bullets of Kitchener’s army. This was bad for them obviously, but it was also bad for the meme. In effect, the meme removed itself from the meme pool through its effects on its hosts’ behavior."

"Members of both sexes can be found at every point on the things vs. people continuum; however, more men than women exhibit a stronger interest in things, whereas more women than men exhibit a stronger interest in people... To get an intuitive sense of the magnitude of the difference, if one were to pick pairs of people at random, one man and one woman, the man would be more things-oriented than the woman around 75% of the time."

"[T]he same sex differences in occupational preferences have been found in every society where psychologists have looked for them. In one large study (N ≈ 200,000), Lippa found the differences in 53 out of 53 nations: a level of cross-cultural unanimity almost unheard of within psychology."

"[A] large meta-analysis by Xu et al. (N = 254,231) concluded that gay men tend to have spatial and linguistic abilities comparable to those of straight women, whereas lesbians tend to have spatial abilities comparable to those of straight men (but female-typical linguistic abilities)... Gay men were presumably subject to essentially the same gender-specific social forces as straight men, and lesbians the same gender-specific social forces as straight women. As such, the near-reversal of the usual spatial vs. language pattern is hard to reconcile with the claim that this pattern is due largely to social forces."

"In the quest to promote women in STEM, academics and activists may sometimes inadvertently overstate the ubiquity of bias and discrimination against women in this sector. An unintended consequence may be to scare away some women who would otherwise be interested in a STEM career... If women are given the impression that the STEM workplace is a hotbed of sexism and an unwelcome place for women, many might quite understandably decide to look for other fields in which to make their mark."

"[P]olicies that artificially engineer gender parity – financial incentives and quotas, for instance – could potentially lower aggregate happiness. To the extent that these policies work, they necessarily mean that some people will be funnelled into occupations that are less in line with their tastes and talents."

"A growing body of work suggests that, in nations with greater wealth and higher levels of gender equality, sex differences are often larger than they are in less wealthy, less equal nations... [R]ather than being products of a sexist or oppressive society, these differences may be indicators of the opposite: a comparatively free and fair one. If so, this casts society’s efforts to minimize the sex differences in an entirely new light. Rather than furthering gender equality, such efforts may involve attacking a positive symptom of gender equality. By mistaking the fruits of our freedom for evidence of oppression, we may institute policies that, at best, burn up time and resources in a futile effort to cure a “disease” that isn’t actually a disease, and at worst actively limit people’s freedom to pursue their own interests and ambitions on a fair and level playing field."

"Based on the foregoing discussion, we suggest that the approach that would be most conducive to maximizing individual happiness and autonomy would be to strive for equality of opportunity, but then to respect men and women’s decisions regarding their own lives and careers, even if this does not result in gender parity across all fields. Approaches that focus instead on equality of outcomes – including quotas and financial inducements – may exact a toll in terms of individual happiness. To the extent that these policies override people’s preferences, they effectively place the goal of equalizing the statistical properties of groups above the happiness and autonomy of the individuals within those groups."

"Although men and women are roughly equally represented in STEM overall, in certain fields, the sex ratios are somewhat unbalanced. More women than men are found in health-related fields, for instance, whereas more men than women are found in fields such as computer science, engineering, and physics."

"[A]lthough we agree that caution should be exercised in discussing biological explanations, we would argue that this is a specific instance of a more general truth, namely that caution should be exercised in discussing any explanations. It is not only biological explanations that can undergird harmful practices. Environmental theories of left-handedness and same-sex sexual orientation, for instance, have been associated with cruel and unnecessary interventions designed to eradicate these innocuous traits. Environmental theories of human sex differences, if taken to extremes, could potentially produce comparable harms. For example, if we assume that sex differences in career choice are necessarily evidence of bias and barriers, and never products of the freely made choices of those best-placed to make them, we may pathologise the decisions of individuals who take a gender-typical path, and enact progressively more coercive practices to eliminate the remaining gaps. Like earlier efforts to force people into the mould of traditional gender stereotypes, such practices may mean that some people are funnelled into careers that do not align well with their interests and inclinations."

"The evidence for bias in STEM is mixed: Although some studies find bias against women, others find none or bias in women’s favour... The mixed findings suggest that narrow-sense anti-female bias is less ubiquitous than sometimes assumed – or that different people have different biases, and these sometimes favour males but sometimes favour females."

"Why should we put a statistical, collective goal – i.e., more equal sex ratios in STEM – above the happiness and autonomy of the flesh-and-blood individuals who constitute those collectives? Why should policy makers’ preference for gender parity take precedence over individual men and women’s preferences regarding their own careers and lives?"

"Most women do not want a career in STEM and nor do most men. Why should the small fraction of women who do want such a career be the same size as the small fraction of men? To put it another way, as long as everyone has the opportunity to pursue a STEM career, and as long as the selection process is fair, why would it be important to get as many women as men into jobs that fewer women want?"

"[W]hy would natural selection give men the physical equipment needed for violence but not the psychological machinery to operate it? This would make about as much sense as giving us teeth and a digestive system, but not a desire to eat."

"By clamping down on male aggression, culture may make the sex difference in aggression smaller than it would otherwise have been."

"Contrary to stubborn anthropological myth, people everywhere fall in love... the idea that romantic love is an invention of Western culture is itself an invention of Western culture."

"A well-designed parental male will tend to end up investing in his own offspring, rather than the offspring of his good-looking next- door neighbor. And one way to help ensure that this happens is to be easily moved to jealousy."

"What accounts for psychologists’ kin-blindness – a blindness so profound it would lead to the vaporization of lazy aliens? Part of the answer is that many psychologists, as I’ve already mentioned, have an empty space in their brains where their knowledge of evolution should be. They know little about other animals and little about the nature of the evolutionary process. This impairs their understanding of their own species."

"As a result of cumulative culture, we have ideas in our heads that are orders of magnitude smarter than we are."

"Albert Schweitzer once observed that “When people are free to do as they please, they usually imitate each other.” This was clearly not meant as a compliment. People quote Schweitzer’s statement to thumb their noses at the way we copy each other – which, when you think about it, is rather ironic."

"It’s often a good idea to adopt the practices and beliefs of the people around you. For one thing, the people around you aren’t dead. If you do what they do – eat what they eat; avoid the dark alleys they avoid – you might continue not being dead as well."

"Whether a trait is natural or unnatural is irrelevant to the question of whether it’s good. Moral worth should be judged not in terms of the naturalness of a trait, but rather in terms of how that trait impacts the wellbeing of everyone affected by it. Thus, violence is natural but bad, medicine unnatural but good."

"[This] paper has two main aims. The first is to examine the evidence that factors other than workplace discrimination contribute to the gender gaps in STEM. These include relatively large average sex differences in career and lifestyle preferences, and relatively small average differences in cognitive aptitudes – some favouring males, others favouring females – which are associated with progressively larger differences the further above the average one looks. The second aim is to examine the evidence suggesting that these sex differences are not purely a product of social factors but also have a substantial biological (i.e. inherited) component."

"[I]f we make the reasonable ballpark assumption that people working in a given field tend to come from the 25% of people most interested in that field, sex differences in occupational interests would account for the entirety of the engineering gender gap and much of the gap in science and mathematics."

"Sex differences in occupational preferences and priorities suggest one possible reason that more men than women go into maths-intensive STEM fields. The reason, put simply, is that more men than women want to go into these fields."

"[A]mong the minority of people who possess exceptional mathematical abilities, the women are more likely to possess exceptional language abilities as well. This means that mathematically gifted women have more vocational options than their male counterparts, and consequently that fewer mathematically gifted women end up pursuing a STEM career. To the extent that this explains the gender gap in maths-intensive fields, the gap results not from mathematically gifted women having fewer options, but rather from them having more."

"[Sociocultural] explanations are vulnerable to a number of criticisms. To begin with, it is unclear to what extent current social influences actually point in the direction these explanations presuppose. According to one study, by four years of age, girls tend to assume that boys are academically inferior, and by seven, boys assume the same thing. Similarly, teachers tend to view their female students as superior at maths and reading, even when aptitude tests indicate that the boys are doing better. Popular culture often mirrors these trends, with girls depicted as academically superior to boys (consider, for instance, Bart and Lisa from The Simpsons, and Ron and Hermione from the Harry Potter series."

"As a result of high levels of male parental investment, humans evolved into a somewhat “androgynous” species - a species in which human females exhibit traits generally found only in males (e.g., competition for mates) and human males exhibit traits generally found only in females (e.g., the provision of parental care; choosiness about mates)."

"Of course, nothing can be said to argue that people are morally obliged to accept this ethic, for to do so would be inconsistent with the ideas that inspired it in the first place. It is an ethic that will be adopted – if at all – by those who find a certain stark beauty in kindness without reward, joy without purpose, and progress without lasting achievement."

"A Ku Klux Klan member would be mortified to learn that he was actually a Black man. Many people’s reaction to learning that they are actually animals, or actually apes, is the same."

"Some may find these conclusions frightening, and perhaps that's an appropriate reaction. But then again, maybe it’s not. For it is certainly possible to frame an ethic consistent with the Darwinian view of the world. Such an ethic might emphasize the virtue of being honest enough and courageous enough to acknowledge unflinchingly that there is probably no God, no afterlife, and no soul; that there is no objective basis to morality or higher purpose behind our suffering; that we are insignificant in a vast and impersonal cosmos; that existence is ultimately without purpose or meaning; and that the effects of our actions will ultimately fade away without trace. It is admirable to acknowledge these uncongenial truths, yet to struggle on as if life were meaningful and strive to make the world a better place anyway, without promise of eternal reward or hope of ultimate victory, and indeed for no good reason at all."

"Even in a pointless universe, pointless happiness and pleasures are surely preferable to pointless suffering."

"It is not clear that people have fully taken on board the idea that humans are animals. If they had, then perhaps academic disciplines such as sociology and anthropology would be viewed as specialist branches of zoology; medical doctors would be viewed as a subtype of veterinarians (one that specializes in tending to the health needs of just one species); human rights would be viewed as a subset of animal rights; and the socialization of children would be viewed as one example of the training or domestication of animals (making parents and teachers a subtype of animal trainers)."
