The issue is one of variance, not mean. When social intelligence is included, I think the average woman is probably smarter than the average man, but men have more variance and are thus more prominent at the extremes. I doubt that there is a strong genetic basis for this. It is probably due, in large part, to the ways boys and girls are raised. Speaking very broadly, and acknowledging the existence of counterexamples; boys are raised to be smart, while girls are raised to be social and cooperative. This means that gifted male children can more easily zip ahead in school, but that the stragglers fall further behind in academic and social skills... and are more likely to end up becoming criminals. A lot of girls feel guilty and insecure about being "too smart" compared to their peers, which holds them back.
