The research I have seen on harassment and discrimination has been very weak in that, among other things, harassment and discrimination are deemed to have happened if/when women say or believe it has. And even improved research would be too recent to have been replicated often -enough to have been considered established. And I have trouble with claims of bias on many grounds , including that I who have lived a reasonably random/rep life, have never seen it happen. I know many women who have careers as professionals of different sorts without having had any special support given to them. Again, if you decide not to take on a difficult path such as a graduate science degree based largely on the grounds of (supposed) bias or peer pressure, then you likely don't have it in you to undertake the grueling effort required. But, I do agree that one of the factors is that women are more reasonable , healthier emotionally, in the sense they seek to have a balanced life not entirely devoted to work, while men are willing to , unhealthily, devote their lives to their works, paying a high price in many regards. But this is in part the result of societal pressures whereby a man is appreciated as a function of being a good worker/provider. It seem many in the Feminist movement believe the hardships women go through do not have a parallel in what men go through. I have never bought into the white straight privilege they so often bring up. EDIT: Ultimately women are just not entering into IT-related careers in high-enough numbers. Just how do you expect anything close to a 50-50 ratio when only , e.g., around 8% of Physics, EE, etc. degrees are pursued by women? Women have it better in many regards than men, they just never bring these up. I have never heard them complain, e.g., about the fact that women are earning some 60% of college degrees nowadays.
