What I say it establishes. That James Damore was referencing mainstream science. One might reasonably conclude that his conclusions are wrong. Here is an example: https://www.youtube.com/watch?v=BIRvtA2JIIA
I think all of those who concluded that he was being a misogynist have no leg to stand on. The accusation is levied just to silence views that are not liked.
I'd also urge you to step back from the Damore framing of this post. I know why it's hard to escape. But I think the author is just using Damore as an opportunity to make a more general statistical point.
I don't have a problem with the article's statistical point. I think there are all sorts of opportunities to make points here.
