It's been spoken about before, but a solid theory never seems to materialize.

My question: why is it that those pushing the boundaries of society seem to be universally male? Especially in an era where females are dominating higher education.

Not many female tech entrepreneurs, engineers, visionaries, etc. Just take a look at the self-made portion of the Forbes list.

It seems that females overwhelmingly tend to only take the "well worn" paths. You very rarely see a woman pursuing an endeavor that has tremendous upside, but also the risk of spectacular failure.

Theories?
