What do people do when confronted with research that challenges the very fabric of modern gender politics?

As more research like this gets out, indicating that males and females really are genetically predisposed to different psychology, what happens to a sizable chunk of leftist politics, which currently allege men and women are identical and that differences in equity are entirely cultural and sexist in nature?

What does this say of modern cultural hiring and university admittance policies that are driven by untested assumptions contradicting research like this?

Perhaps our past measures of merit have not been so skewed as some people with an axe to grind would have you believe.
