Why can't a man be like a woman?

It's the X chromozone versus the Y. There's over twice the genes on the X and so the X wins. The result? The male bell curve on intelligence, violence and a host of other things tapers much further to the extremes.

I very much doubt that this causal link between allosome size and the IQ bell curve has much scientific merit. I've read in several places that people very much doubt that the effect is even relevant in explaining perceived IQ differences.

I haven't looked at the explanations for the reason in quite some time. You may well be right.
