It's well established that males have higher risk tolerance than females, including crossing over into risk seeking behavior at a much higher rate. Females of the human species are observably and consistently more risk averse - and I believe this carries through to the vast majority of mammals, except maybe hyenas and a very few other female-dominant species. The generally accepted theory is that the cost of gestation in placental mammals leads to risk aversion as a result of natural selection. Females who avoid risk have a higher likelihood of having more offspring than those that don't.But you're right, men are generally more welcoming to non-conformists. Why? Is it because they're better people than women? As a man, the idea flatters me, but I don't have any logical reason to accept it. Especially since there's another explanation: that men have higher risk tolerance, because we are less vulnerable than women. Non-conformity can signal potential threat (this too is logical), and women are more sensitive to danger than men. This isn't a moral fault of women, it's a logical response to a difference in circumstance.
And in a rather large number of mammalian species... males of that species are one of the risks.
