My evidence is anecdotal, but think about it -- Russia recently decriminalized domestic violence, not exactly the hallmark of gender equality, that's surely not the reason why more females are interested in IT in Russia.
I was not suggesting that females are inferior to men, just that males and females will make vastly different life choices because of psycho-evolution.
It's a scientific fact that while male and female median IQ is the same, men have much more variability (more men at the extremes).
Just think about your reproductive strategy(not necessarily in the modern monogamous society)-- you have bilions upon billions of sperm replenished every day while females produce one egg per month. A smarter/fitter man can produce much more offsprings than a smarter/fitter female. That has got to produce some profound differences in the way men and women behave.
Centuries ago there were no women scientists, now there are, so does that mean the people like you in the transitory period claiming "Women can never be scientists due to psycho-evolution (whatever bullshit that is)" are right.
Without scientific evidence, your psycho-evolutionary boundary on what is achievable by men or women is just convenient excuse for sexism because it changes and is arbitary.
What I AM saying is maybe, just maybe there's no conspiracy against women and that women and men make different life an career choices which can simply be explained by bullshit psycho-evolution.
Without fail, during any discussion about tech and gender on these boards, "nice guys" come out of the woodwork as staunch advocates of equality in the workplace, their message couched in accusatory and bullying language.
I'll bet they're closer to being part of the problem with the industry, rather than the solution.
In my opinion, it's obvious that women being under represented in STEM is caused significantly by both evolutionary /and/ cultural factors.
