“…(A) scientific study just published in American Psychologist provides strong reasons to doubt that there are many inborn differences between genders. Janet Shibley Hyde, of the University of Wisconsin-Madison, has shown that in most cases psychological differences are small or non-existent. It turns out that there is no difference in how good girls and boys are at maths. Girls’ self-esteem is widely believed to nosedive on entering puberty; in fact, that of boys does so as well. In most respects, the genders communicate in the same way — forget all that stuff about men interrupting more and being less self-revealing.

Only a handful of the nostrums of evolutionary psychology survive Shibley Hyde’s scrutiny. It’s true that women can’t throw things as hard or as far; they do not masturbate nearly as much, and are not up for casual shagging to the same degree; and they physically attack others dramatically less often. Taken overall the study shows that, to a very large degree, in terms of gender difference, we do start as blank slates, and it provides one of the strongest ever scientific foundations for equal-sex social policies. But then how could we ever have doubted it?” (Mail & Guardian)
