The Implicit Association Test (IAT) is a popular means of examining "hidden" biases. However, some express concerns about classroom use of the IAT, citing students' potentially negative affective reactions to taking the IAT and discovering their implicit biases. To investigate the validity of this criticism, 35 social psychology students completed affect measures after taking and discussing the Race IAT. Students reported more positive than negative affect both immediately after taking the IAT and 1 week later. They also reported greater awareness of their own and others' implicit racial biases, knowledge of implicit processes, and perceived value of the IAT demonstration.
