Why are men so stupid?

Why do men seem to always follow their dicks and not their brains? Nature or nurture? TV? Internets? Why the fuck are men so fucking stupid?

I just don't consider better logical capacity and physical strenght as that superior, but it's true that somewhere in history men have outsmarted and "oppressed" women. Otherwise we would have crazy matriarchal society or some "true equality" fantasy society.
