When I was younger, I believed that gender was more about differences on the outside... that inside, gender was largely a social construct.

As I've gotten older, I've seen how gender can also correlate with certain differences in approach to things. I don't think it's causal, but the correlation is striking at times.

It took me maybe a decade and a half to shift my perspective, as it was one that I just didn't want to accept. But now I see gender as a biological construct, upon which we layer all sorts of social stuff. But I've come to believe that gender does have more impact on how people think and act than I would like to admit.

What do you think: is gender a social construct? A biological one (beyond the obvious, that is)? Something else entirely?
