Is tarring thousands of people with the charge of rampant sexism really the only hypothesis we can discuss every time this issue comes up?
You ask me what "natural disinclination" I think women have, but you're getting the logic backwards. I'm suggesting that if you look at the data that it may suggest the idea that maybe there is a natural disinclination, not that I axiomatically assert that there is one and therefore it is the explanation. Can we at least consider that hypothesis, rather than implicitly and rather frequently accusing engineering of being somehow the sole holdout of troglodytes and evilly conspiring to hold down the little girls, who have somehow managed to transcend all the other evil conspiracies in all the other fields but just can't seem to shake this one?
