sorry for i haven't read the whole thread, so if it's already been said just ignore me...

men are more probable to be genious. why? the intelligence "lays" on the X-chromosome. since men have both X and Y, there's only one X that has to be the genious chromosome. women have two X-chromosomes, so both X need to be intelligent. obviously, the gaussian normal distribution is somewhat flattened for men, for women it has a higher peak around 100 (i speak about the IQ here). as a result, there are more ingenious men, but well, also more jerks.

joey.
