But you can't remove societal influence? This is the issue, you can't test against "no societal influence". And societal influence is that powerfull of a factor for comportments that any biological factor is negligible. Or maybe gender difference is only a small factor and not a negligible, one but how do you test for that? It is impossible.

I have a sightly ethically challenged experiment i would like to run...
