asleif_dufansdottir - I agree. I particularly like the evolutionary psychology approach, but I know it is very controversial. I am not in a scientific field... I'm off in the happy land of liberal arts, where any talk of biology is scorned like nothing else. Heaven forbid our genetics play ANY role in the way we are... hmmmmm...
I've read many books for my own field from the "socialization is everything" camp... and while I agree with some aspects, I personally am more inclined to fall on the biological side of the argument. But that's just me, and many people who are much more educated, I'm sure, think differently. To each their own!
