I think I will quote the statement that Pinker made for the presentation. I may add a few other points, but Pinker really summarizes what I want to say. The quote I am referring to is listed under my post, "Good Summary".
I will mention how Pinker thinks that the belief that individuals are born "unisex" and then shaped by environment from there on out is becoming less credible.
Another quote I'd like to add is this, from the Salt Lake Tribune:
"Pinker's point is that men and women are very much the same and yet quite different, and many of those differences exist in every culture on earth. Even in places such as the Israeli kibbutz, which has tried to be gender-neutral in assigning roles, Pinker notes a gender-specific aspect to the division of labor: Women in all cultures have more responsibility for raising children, while men are more dominant in the political realm. Men in every society are more driven by the prospect of sex and are more aggressive in general.
There is nothing to fear from acknowledging that men and women have different psychological tendencies. What we should fear is the hysteria that occasions the speaking of uncomfortable truths. The academy is a place where all ideas should be welcome - free to rise and fall on their own empirical merit. But don't expect that to happen at Harvard any time soon."
