This shows that psychology professors in the US are ~10:1 liberal to conservative, almost as extreme as EA. So I think there are data to show that there is little ideological diversity in academia, especially the humanities, social sciences, and arts.
There’s a lot more to diversity than the liberal/​conservative ratio. I could come up with any partisan divide to argue anything I want, e.g. economics academia has very little diversity because the ratio of communists to capitalists is 1:100, or philosophy academia has a lot of diversity because the ratio of liberal feminists to radical feminists is 1:1, or something like that.
