I agree that there are societal norms, and that these may shape our behavior, and I agree that we're "diamonds in the rough" in the sense that we have tremendous control over our own destiny, but there are gender differences too, even among children too young to have been influenced by culture (
this study, for example). Clearly, our brains tend to be very different.
Also, I love this quote from the abstract: "girls are more object oriented." I knew it! C++ is oppressing me!
