Well, maybe this article explains something.

“Academics in the UK claim their research shows that men are more intelligent than women. A study to be published later this year in the British Journal of Psychology says that men are on average five points ahead on IQ tests.

Paul Irwing and Professor Richard Lynn claim the difference grows when the highest IQ levels are considered. Their research was based on IQ tests given to 80,000 people and a further study of 20,000 students….At scores of 155, associated with genius, there were 5.5 men for every woman.”

Actually, this might be a good reason for sending women to college, since men know so much already it might help to level the playing field. Now if they could just explain why men never stop for directions, we could solve all the problems of the universe!
