Despite the media scare stories, trigger warnings are not widely used by college professors across the country, according to a survey released in full on Tuesday. They're not even widely demanded by students. And when they are used, the warnings address both liberal and conservative concerns.

The nonscientific survey, conducted by the National Coalition Against Censorship , is the first of its kind to gather data on the actual use of trigger warnings in college classes. The conclusion: While professors are fretting about the possibility, there is "no crisis."
