I like how the documentary investigated studies on nature vs. nurture. One thing I do admit is that it&#x27;s very difficult to measure how much of it is genetics alone, since we can&#x27;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&#x27;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&#x2F;biologic nature seems to want to resist.<p>I don&#x27;t think there&#x27;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&#x27;t be quite so divergent. We&#x27;re still a society in transition, and it wasn&#x27;t very long ago where women weren&#x27;t allowed to have career opportunities at all, it will be interesting to see how the numbers change in another generation or two.
