My only evidence is that I didn't hear of one. Didn't even hear about the studies. Perhaps they just confirmed what everyone already thought or wanted to believe or the gender disparaged by the studies didn't care enough to raise a fuss. Whatever the reason.
I did hear about the president of Harvard being fired though. I read about The Bell Curve. Damore. The list goes on and on. You must know what I'm talking about.
Maybe I'm just biased so I filter bubble out evidence that sexism is sexist.
