Completing the implicit association test reduces positive intergroup interaction behavior.

It is frequently suggested that increasing awareness of intergroup bias and limited control over biased responses can improve intergroup interaction behavior. Some uses of the Implicit Association Test (IAT) epitomize this approach to improving intergroup relations. However, if completing the IAT enhances caution and inhibition, reduces self-efficacy, or primes categorical thinking, the test may instead have negative effects. Two experiments demonstrated that when White individuals completed a race-relevant IAT prior to an intergroup interaction (as compared with when they did not), their interaction partner left the exchange feeling less positively regarded. No such effect was evident when White individuals completed a race-irrelevant IAT (Study 1) or an explicit prejudice measure (Study 2) before the exchange, or when their interaction partner was White (Study 1). Mediation analyses (Study 2) suggested that White participants who completed the IAT communicated less positive regard because they adopted a cautious approach to the interaction, limiting their self-disclosure.
