What I object to is the belligerent fools who would get upset at this. I have had people argue to me endlessly about how this proves that men are 'better', or that women are 'better', in some Absolute, Ultimate way. Women are better at some skills, on average, and men are better at some skills, on average, but there is some crossover too. There is crossover, because mistakes happen during development in the womb. Males and females are clumsily constructed, because Nature is not perfect.
Nature is sloppy.
So there is crossover, and sometimes, occasionally you will have a female mathematical genius with superb spacial skills. The same goes for males with superior language skills, or incredible grasp of emotion and facial expressions. Interestingly, in the latter, such is most commonly associated with also being gay, which is not surprising really, because male homosexuality can be defined as a partial, incomplete, transsexualization of the brain. This is born out by the same PET, CAT, and other tests that show sex linked brain functioning already. No skill set is better in an Absolute way than any other.
