National Review Reports: A team of researchers measured contemporary levels of censorship in the American academy. Simply put, cancel culture is no myth. Academic censorship just got accurately measured.

For the prestigious professional journal Proceedings of the National Academy of Sciences (PNAS), a team of top academics — which, in the interest of full disclosure, included Yours Truly as a bit player — recently attempted both to examine contemporary levels of censorship in the American academy and understand the motivations behind it. The results obtained by our team, led by UPenn’s Cory Clark, were interesting and to some extent not very surprising — but deeply unsettling.

Censorship is extraordinarily prevalent across modern academia. Per one large data set reviewed for the project, 34 percent of all tenured and tenure-track faculty members report open “peer pressure” to “avoid controversial research.” Interestingly, the motives of today’s bluenoses seem to be, at some level, positive ones (Clark uses the term “pro-social”).

Censors genuinely want to interfere with the spread of ideas that they see as racist or sexist, rather than to simply exercise power. However, the in-practice effects are the same: Since contemporary leftists see almost everything as racist and sexist, the effects of the theoretically moral motivations that dominate on today’s campuses are frequently absurd — i.e., the resignation of Harvard president Larry Summers after he noted that men and women are different.
