Citations are legion. The most obvious and direct proof is the huge variation in math scores by country. If there was no social bias against women in mathematics, you would expect girls to be equally worse than boys in every country (they way girls are shorter than boys in every country, for example). eg see: http://www.economist.com/science/displaystory.cfm?story_id=11449804 http://www.economist.com/science/displaystory.cfm?story_id=1... and note the significant difference in the gender gap in math between, say, Turkey and Sweden. Arguing about mathematical skills is irrelevant to the debate anyway. I can tell you for certain that at least half the male programmers I deal with seem to possess no particular mathematical insight. The real question is not whether more women should be in computing. The question is whether there are women who would be enthusiastically in the field if they had been encouraged to be, and whether their absence is impoverishing the field. I have no data to answer to this question and I doubt you do either. PS. I am female, if that matters.
