This is a question I've often posed to friends of mine, and the responses I've gotten seem to point to societal pressure. Most women whom I've asked have said that they were told at some point in their careers that they couldn't or shouldn't work in math, science or computers, because they were female. Some of them where good at it in school, but just didn't feel a calling for it, but who I most feel for are some of the women who actually enjoyed it in school, but felt deterred. I hope that, in general, we stop assuming people do things for biological reasons, unless there is strong evidence otherwise, and even then we shouldn't live by stereotypes.
