> hormonal differences rather than sex differences it wouldn't be as intrinsically controversial.

it is controversial only if you assume that

- we can control sex differences more than hormonal differences (in fact it's quite the opposite)

- cultural differences are more controllable than biological differences (same as above)

it doesn't matter how you frame it, the study shows a clear tendency, we can discuss the implications or the correctness of the study, methodology and title

For the first a functioning brain it's enough, for the rest we are subject to burden of the proof.
