> There's no biological reason why there shouldn't be a roughly equal proportion of women in STEM, just social anachronisms.
That's an assumption. We don't know. :-)
I don't know that future neuroscience is going agree with that statement. The male and female brain do differ on average, and it would seem that these differences may be related to the types of thinking that STEM encourages. Math maybe not so much, but engineering? Maybe. We don't know for sure yet. A lot of people love to think that there's no difference between men an women, but science chips away at that idealism every decade.
But there's no reason to treat men or women any differently with regards to STEM, true. We just have to remember that there may be some base-level biological self-filtering that happens. And if it does, that's OK.
