It's disappointing to see so many people here read the title of the article and immediately start the see,-social-differences-are-the-result-of-vast-differences-between-the-binary-sexes wheel rolling again. It's nowhere near a valid conclusion from the article's content. There are racial differences in gene expression (though much smaller), too, but I doubt anyone would upvote it or start a similar conversation about race if an article about it were posted here.

There are clearly differences between the physiology of the average man and the average woman, but those differences appear to be more of a spectrum than a binary split. Given that, I don't understand how people with an axe to grind against the "gender is cultural" idea would like society to look. Why argue against the idea that individual differences are vast, and that the best approach is not to create groups that are defined at birth? What's the alternative being suggested?
