Why should people respect formal education?
Even in many "scientific" fields, standards are so low that most published research is wrong. The non-scientific parts of academia are dominated by in-group politics and shallow status seeking. And in much of academia, evidence is less important than ideology: research and researchers are banned not because they are wrong, but because their ideas are unacceptable.
If academia wants respect, it should work on improving itself instead of trying to find a "strategy that works against populism".

> Four studies found that the proportion of professors in the humanities who are Republicans ranges between 6 and 11 percent, and in the social sciences between 7 and 9 percent.
> Conservatives can be spotted in the sciences and in economics, but they are virtually an endangered species in fields like anthropology, sociology, history and literature. One study found that only 2 percent of English professors are Republicans (although a large share are independents).

> When Inbar and Lammers contacted [social psychologists] ... they found that ... the climate in social psychology was harsh for conservative thinkers. ... Participants were asked about the environment in the field: How hostile did they think it was? Did they feel free to express their political ideas? As the degree of conservatism rose, so, too, did the hostility that people experienced. Conservatives really were significantly more afraid to speak out.
> Over all, close to nineteen per cent [of social psychologists surveyed] reported that they would have a bias against a conservative-leaning paper...and thirty-seven and a half per cent, against choosing a conservative as a future colleague.
