This is an interesting paper about the differences between men and women. You might set aside some time to read it.
It addresses the delicate point that there seem to be more men of ability in some areas (science, Chess, genre-creators in music, etc) with a much more plausible explanation than the conspiracy theory that throughout all cultures and times, men have kept women down. The author explains that the entire notion of "men vs. women" is a screwed up way to look at it, and that the actual evolutionary issue is "groups (that contain men and women) vs. other groups (that also contain men and women)."
The author suggests three main reasons we see such a disproportionate number of men at the top of so many fields. My summary is as follows:
1) Nature plays dice much more with men than women. Men are at the top of a lot of things, and they are also at the very bottom of a lot of things. Most people in prison are men. Even with height, it varies more with men in BOTH directions (meaning there are a lot of men way shorter than the male average, moreso than women way shorter than the female average). Though there appear to be more men at the top levels of IQ, there are more men at the BOTTOM levels as well. In the set of people who are mentally retarded, the more severe the case, the more likely the person is to be male, and below a certain point, it's basically all male. Though the average in IQ and many other things can be the same in both sexes, it's males nature takes chances on and ends up with more extremes in both directions. Also, I thought his notes about how deceptive the stats for minimum wage and grade point averages were interesting.
2) Evolutionarily, men need to stand out. The author presents a staggering statistic about how many of our ancestors are female as opposed to male. Twice as many are female! Although half the people who have ever lived were female, that's not the same stat. 80% of females who have lived passed on their genes (passing on genes means "ancestor" here), while only 40% of the men who have lived passed on theirs. Men are in a tough situation, and would do well to separate themselves from the pack, perhaps by accumulating wealth or power or skills, or something. The author says the number of times a group of 100 women have gotten together to build a ship to sail to far-off-lands is basically never, though men have done this many times throughout history. If you have an 80% chance of reproducing, it's just a better strategy to play it more safe and pick amongst the many men who are available to you. No need to build a ship or conquer some other land. And so evolution gave men a REASON to peruse all the crazy things they do, and to be passionate about them. To put it another way, the set of women geniuses who are just as able to be great at science as men contains fewer who WANT to devote themselves to such things.
3) Men's "relationship spheres" are different than women's. Women care about deep 1-on-1 relationships, and lucky for us, this has allowed our species to actually survive. Having families and raising young is pretty central to carrying on the species, so this preference of women's is not "worse." Quite the contrary, it's mission critical. Men's preference is to have a larger sphere of more shallow relationships. If you look at violence in the home, women actually commit it more. If you look at violence amongst "shallow relationships" such as going to the mall and getting into a knife fight, men commit it radically more. In each case, it's just the sphere that gender cares about more.
While the woman's sphere has allowed us to perpetuate the species, it has mostly stayed the same over the centuries. But the men's sphere is what enables science, trade, corporations, and so on. The men's sphere over time allows a culture to accumulate knowledge, wealth, and power. When your group of men+women is competing against other groups of men+women, your group is going to be in great shape if the women are great at their sphere (necessary for survival) and the men are great at theirs (not necessary for survival, but bring power to your group overall).
Given these three points, it's not hard to imagine that most CEOs (and even Chess players) would be men, even if the average intelligence of a man is exactly the same as for a woman (which is does appear to be). I know it's a delicate subject, but I think the author does a great job of not even mentioning any morals about what "should be," only looking at what is, and explaining how evolutionary forces created these specializations. To any particular man or woman who wants to excell at the other's stereotypical sphere: go ahead! Anyway, if you have comments, better to aim them at what the paper says, rather than my imperfect summary.
