>One study found, for example, that a third of social psychologists admitted that they would be unwilling to hire a known conservative to the faculty, and nearly half thought that their colleagues would be unwilling to hire such a person.33 Subsequent work suggests that those findings are not limited to psychology, and that conservative scholars might have a similar willingness to discriminate against liberals.34 On the whole, there does not appear to be a robust pipeline of conservatives desperate to get into academia.
This is substantially different from what you are suggesting, this idea that there is a natural bias when it seems to be a supply problem (and a dismissal of academia entirely, as the article links together the larger conservative push against higher education). Can't hire that which does not exist or believes your field is a farce.
