How do you know that? Very little evidence is offered. The other side is quoting studies about bias in hiring, and the reply is basically &quot;we would never do that, trust us&quot;.<p>Edit: re self-selection, two points:<p>1. If the self selection occurs at the student levels (i.e. professors are hostile to conservatives which causes them to drop out of academia before they get to the teaching level) this is still bad.<p>2. Even if it&#x27;s entirely self selected, it&#x27;s still a diversity problem.
