I was under the impression that most people had accepted that the reason more men than women do software development is that more men find it interesting than women do, not because women are less intelligent or because there's a conspiracy to keep them out. Too bad, I guess not.

As an aside, my boss at the moment is a woman, and a few years ago she had to staff up significantly and hired several young women at the junior level. The interesting thing is that her team hasn't really changed because of "the diversity" since it turns out that women who like programming act pretty much like the men who like programming: they're kind of socially awkward, have sometimes unreasonable expectations that the world will be a meritocracy, make a fetish out of liking cartoons and movies that most people don't, and so on.

No.

At least, I've certainly seen no research suggesting that is true; you may believe it but "most" people don't and if they did they haven't provided evidence for that belief. If your hypothesis is correct, how do you explain the massive variation over time in gender gap even just in the United States?

If you're talking about the sharp decline in computer science degrees granted to women around 1984, I have a couple of guesses.

First, no one really knew what kind of career path getting a computer science degree entailed until around then anyway, and once women had figured it out they decided they didn't want it.

Second, in my opinion women are much more sensitive to their career's stability and predictability than men are, for the simple reason that they're the ones who have to plan out when to have children. You'll notice that the drop-off more or less coincided with the first (or second, or maybe third - I forget which) big bust in the PC industry in the 80s. Mainframes and even microcomputers did not have boom-and-bust cycles like PCs did in the 80s, although individual companies might blow up the industry as a whole was relatively stable. College students looking for stability around that time might sensibly decide "computing" wasn't for them any more.

My favorite reference in this discussion (well, about women in science and engineering as a whole) is Philip Greenspun's article (http://philip.greenspun.com/careers/women-in-science) who basically makes the argument that the median scientist who doesn't win Noble Prizes actually has a pretty crappy career and that women are smart enough to stay away.
