[T]he strong emphasis on increasing the numbers of women in male-dominated fields is arguably somewhat sexist. As Susan Pinker argues, it tacitly ass… - Steve Stewart-Williams

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.

Just as our tools evolved culturally to fit our hands, so too our social roles evolved culturally to fit persisting aspects of the human mind. Roles that jar too violently with human nature are unlikely to persist for long, at least without the application of significant social force. If this is correct, it raises the possibility that some social roles might have evolved culturally to fit traits that, although found in both sexes, are more common in one than the other. This is emphatically not to say that there are some male roles and some female roles. But it is to suggest that there might be some social roles that suit more men than women, and others that suit more women than men — not just because of evolved physical differences but because of evolved psychological differences as well.

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).
