"Boys don't count?" What a crock. Of course boys count. So do African-Americans, Asians, Latinos, women, autism-spectrum people, and pretty much every other identifiable subgroup you can think of. Here's a clue: no subgroup has more innate ability for CS than any other. Unless your chosen subgroup is "people who have innate ability for CS."
Every time the gender imbalance in CS comes up on Slashdot, we see the same phenomenon: a huge phalanx of men jumps out and tries to defend their ignorant biases. Actually, it's kind of generous of you folks: by loudly proclaiming your prejudices, you make it easy for savvy employers to avoid you. Because frankly, one hugely skilled guy who pisses off ten talented women just isn't worth having around.
In the interest of full disclosure, I'm one of the two people (both men, BTW) who taught the first Harvey Mudd course for students with experience. (See TFA if that isn't meaningful to you.) We weren't the first to figure it out (that credit goes to CMU) but we were the first to do it in a compelling intro course (I don't get credit for that either--write me privately if you're dying for details of how I fell into it). But I'm currently the only one who teaches that course to experienced students. The whole idea was originally developed by two amazing men (not me) and one brilliant woman (not Maria Klawe, BTW; she'll tell you that herself because she wasn't even at Mudd at the time). So let's not pretend that anti-male bias was a factor.
But what has been found based on *science* (oh, that) is that some groups of people, women included, are easily intimidated by show-offs. Which, if you haven't caught on, includes most of the noisiest Slashdot crowd. By and large, these are people who are fascinated with computers and don't have the social skills to see that some of their questions and opinions are irrelevant to whatever discussion is going at the moment. So they blurt out their questions, and the intimidated ones think (this really happens) "Maybe if I don't know the multiply cycle times of the latest Intel chip then I can't do CS." And then we lose those people even though they're incredibly gifted. (BTW, this example was taken from a class this week--and the person who announced multiply cycle times was wrong. Which is often the case in these situations, but they still intimidate others because they make their statements with such confidence. But I politely pointed out that the information was irrelevant, giving the rest of the students a chance to concentrate on the material that actually matters. I can only hope that the message gets across.)
The data is incontrovertible. Gently shutting down the show-offs (most of whom aren't even trying to show off; they're just eager and socially inept) doesn't discourage them in the least. But it keeps them from discouraging others. The result is more total people majoring in CS, and a far wider variety of ideas. All benefit, no loss.
If you feel threatened by that, I suggest that maybe *you're* the intimidated one. And I encourage you to try to develop your self-confidence by taking pride in your own strengths, rather than dissing complete strangers.
