Steve Stewart-Williams Quotes

The amount of suffering and pain caused by the tyranny of human beings over other animals (particularly in food production) far exceeds that caused by sexism, racism, or any other existing form of discrimination, and for this reason, the animal liberation movement is the most important liberation movement on the face of the planet today.

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).

Psychology has made a lot less progress than it could have because too many psychologists know too little about other animals.

[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.

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.

If we decide – and this is our decision; it’s not imposed on us from above – if we decide that reducing the amount of suffering in the world is a good ethical principle to live by, then it becomes entirely unjustified and arbitrary to extend this principle to human beings but not also to extend it to other animals capable of suffering. Why should the suffering of nonhumans be less important than that of humans? Surely a universe with less suffering is better than one with more, regardless of whether the locus of suffering is a human being or not, a rational being or not, a member of the moral community or not. Suffering is suffering, and these other variables are morally irrelevant.

Even in the age of science, we understand the motions of the distant, ancient stars better than we understand the organism observing them: ourselves.

A similar analysis applies within the realm of mate preferences. Several commentators pointed out that sex differences in human mate preferences are generally quite small... As such, the central claim in EP [evolutionary psychology] should probably be "Human beings evolved to put a fair amount of weight on good looks in a mate" rather than "Men evolved to put more weight on good looks than women." Again, the latter statement is true but potentially misleading. This sounds like a contradiction, but it is not; the statement is misleading if it is given undue weight.

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.

[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.

We are a species in which both sexes have their equivalents of the peacock’s tail. Indeed, when it comes to physical beauty, the usual sex difference has arguably been reversed: Females are the “showier” sex.

It is therefore a curious fact that our dominant mating system is more like the typical mating system of birds than that of most mammals, including our nearest relatives, the Great Apes.

Human beings are, by nature, the kind of animal that falls in love. The cross-cultural record also suggests that humans are also the kind of animal that commonly provides biparental care for its young. In 95% to 97% of mammalian species, only the females care for the young. We would no more expect males in these species to invest in their offspring than we would expect them to get pregnant or lactate. Humans are not like that.

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.

[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.
