What Drives Censorship on College Campuses? -- by Peter Arcidiacono, Cory Dowd, Matthew Lilley

There has been widespread concern about self-censorship on university campuses, and especially that conservative voices are being stifled. Using survey data from a private elite college, we show that self-censorship is not simply about being conservative: it is students with the most moderate views who self-censor the most. This pattern is associated with confidence and salience — students who are more confident in their views or who see an issue as especially important tend to hold more extreme views and to self-censor less. At the same time, conservatives self-censor at higher rates than liberals, and the same individual is more likely to self-censor on the views where they are relatively more conservative than on those where they are relatively more liberal; conservatives are also far more likely than liberals to cite concerns about social exclusion as a reason for self-censoring, and report self-censoring less outside the university community. Groups perceived as marginalized self-censor less than majority groups, and especially so on issues salient to them (e.g., Black students on BLM).
