Cornell law professor Sherry F. Colb describes the recent trend among professors to give “trigger warnings” prior to discussing sensitive materials with students and explains why she has chosen not to provide such warnings to her students. Colb points out that there is no reliable evidence that the warnings work as advertised; rather, they might actually do more harm than good. Colb concludes that an education necessarily means encountering ideas and theories that do not sit well with what one already believes, and students should not have the right to skip days or receive warnings when professors will be talking about unwelcome facts or theories.
