I like how the documentary investigated studies on nature vs. nurture. One thing I do admit is that it's very difficult to measure how much of it is genetics alone, since we can't raise kids in a lab isolated from the outside world to ensure 100% that there is no outside cultural or parental influence that may skew the results. That steps on some ethical toes as well. While it's gotten much better, there is still a great deal of culture, advertising, parenting, etc that can subconsciously influence gender roles. Although it looks as though you can only influence people so much, at innate genetic/biologic nature seems to want to resist.

I don't think there's an answer to it either, but to me it looks like while biology and genetics do have some sway, so does environment and culture- enough where the current gender percentages probably shouldn't be quite so divergent. We're still a society in transition, and it wasn't very long ago where women weren't allowed to have career opportunities at all, it will be interesting to see how the numbers change in another generation or two.
