Recent research on the effectiveness of content warnings suggests they are generally not helpful for strengthening learning and growth, nor are they particularly effective at preventing trauma responses and minimizing unproductive discomfort (Sanson et al., 2019). Other studies have found that content warnings do not work for the audience they are intended for—people who have experienced trauma—and may, in some instances, be countertherapeutic for them (Jones et al., 2020).
However, the use of content warnings do increase students’ belief that they are necessary for sensitive topics (Boysen et al., 2018). Some instructors choose to use them to communicate sensitive material that exists in a course for the purposes of transparency and inclusion. A National Coalition against Censorship 2015 survey of faculty found that most instructors who use content warnings do so globally on a syllabus and not locally for specific assignments or readings, citing their belief in academic freedom and teaching their students how to engage with challenging and difficult ideas as they learn to listen, compromise, and discuss in classroom settings.
