- Women are cited less
- Women publish less.
Other people are addressing the first... and how his statistics aren't sufficient to show a lack of bias.
I think the second is on even weaker grounds. That could easily be the result of discrimination by professors, collaborators, reviewers, etc. in deciding who to work with, how early to try and get students work published, whether to accept or reject something for publication, etc. I have no real evidence for this, he has no real evidence against it.
If I was going to expect discrimination somewhere in the process. It would be professors and collaborators who actually see the person they are working with. And it would be by people reading papers many years later based on the reputation of the authors name instead of the content of the paper. Neither of which are disproven by any of his slides.
That said - I find the fanatical attacks from the side I am currently arguing for far worse than the work itself. Ignoring and punishing people for opinions isn't just wrong, it encourages them to hold the opinions more strongly in secret. Open discussion is key, and we should know that as a society by now
