Having kids teaches you that there are natural differences between the two. I have a niece and nephew that I babysat extensively and the differences were so clear. One of the first things my niece came to realize was not wanting to get her hair wet when swimming because she didn't like how it looked. She maybe spoke about 6 words at the time, but was already fashion conscious. My nephew was a typical rough and tumble boy from birth. He was not into playing dolls with his sister and instead wanted to run outside, swim, and do more athletic activities.

Raytri, one difference is that some studies are done on the brain and various brain matter that are not impacted by societal traits such as those your wife suggested. Additionally, much of what she suggested is not true today. I think a larger impact is that women are more comfortable around women, men are more comfortable around men, blacks are more comfortable around blacks, whites are more comfortable around whites, etc. And the fact is that there are very few female scientists. So as the article points out, it requires women to work outside of their comfort zones their entire lives. So from early on I'd suspect many women are turned off at the idea of science as a career. And that impact the learning curve.

However, I find it interesting that when the Harvard President suggests it everyone focuses on him and calls for his job instead of addressing the issue at hand and if there are ways to improve on it.
