That brings us to the bad news:

While majorities favor more viewpoint diversity and free-speech norms, an intolerant faction of roughly a quarter of students believe it is okay to silence or suppress some widely held views that they deem wrong.

Students across political perspectives engage in classroom self-censorship.

Students harbor divisive stereotypes about classmates with different beliefs, and a substantial minority are not open to engaging socially with classmates who don’t share their views.

Disparaging comments about political conservatives are common.

To measure student tolerance for views with which they disagree, the researchers chose matters of ongoing controversy on campus––the fate of a Confederate statue, affirmative action in admissions, immigration, health care, climate change, and whether Christian bakers should be compelled to make cakes for gay weddings against their will––and presented students with mainstream positions that a liberal or conservative classmate might hold. Respondents were asked to indicate which among those positions they found most objectionable.
