"In an article published last year by Inside Higher Ed, seven humanities professors wrote that the trigger-warning movement was “already having a chilling effect on [their] teaching and pedagogy.” They reported their colleagues’ receiving “phone calls from deans and other administrators investigating student complaints that they have included ‘triggering’ material in their courses, with or without warnings.” A trigger warning, they wrote, “serves as a guarantee that students will not experience unexpected discomfort and implies that if they do, a contract has been broken.” When students come to expect trigger warnings for any material that makes them uncomfortable, the easiest way for faculty to stay out of trouble is to avoid material that might upset the most sensitive student in the class."
