As someone who has been drunk on testosterone most of their life, I can testify it is a powerful and fun drug. Perhaps if research was framed in terms of hormonal differences rather than sex differences it wouldn't be as intrinsically controversial.
Does culture play a role in behavior? Probably. But is there an inherent difference between the sexes? Yes.
Plenty of biologists see what happens, and toe the line so they can keep their lives and pay their mortgages.
This is similar to the claims that "race" predicts health issues, when actually it's usually some specific gene which is only correlated with race.
I don't see how it helps to introduce that extra layer of indirection.
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.
