When communicated in a humorous way, racially prejudicial comments may be dismissed as "just jokes." The current study investigated White undergraduate students' antiracist responses to different types of prejudicial comments. Participants (N = 252) were randomly assigned to read about a peer who denigrates Black intelligence by either joking or making a nonjoking statement. Compared to those in the statement condition, those in the joking condition reported less negative evaluations of the speaker and less assertive responding. Students' own symbolic racist attitudes moderated these effects; those who endorsed stronger symbolic racism reported less assertive responding but only in the joking condition. Furthermore, students in the joking condition tended to evaluate the speaker less negatively than did those in the statement condition, leading to less assertive responding to jokes but only for those who endorsed at least moderately high symbolic racism. These results indicate the need for practitioners in higher education to explicitly promote prosocial responses to disparaging racial humor to foster a more inclusive campus climate.
