What you're saying is most probably, from what we know, part of the picture, but it's not the whole picture. For example women aren't just going to social fields cos they're more inclined, but also because someone (society) inclines them. As the short section where I wrote about math demonstrates, women are disencouraged from going into scientific fields, whereas men are encouraged. There are women who are leaps and bounds above me specifically at math, so encouraging a woman like that to go to the social sciences, while encouraging me to go to the sciences, would do a disservice both to her and to me and to our fields. We should do as much as we can to probe the specific talents of individuals rather than groups. But we shouldn't be blind to biology either.
