Although intergroup contact is a very effective method of reducing prejudice, negative expectancies about interacting with outgroup members often create a barrier to intergroup contact. In a series of six studies, cognitive appraisals by which negative expectancies may arise were investigated. Studies 1–4 examined the relationship between perceived outgroup knowledge and resource appraisals in the context of intergroup interactions and experimentally investigated the influence of perceived outgroup knowledge on negative expectancies. In Study 1, a novel method was devised to manipulate perceived outgroup knowledge. Using this method, Study 2 provided evidence that individuals perceive outgroup knowledge as a potential resource when they anticipate having an intergroup interaction. Study 3 extended these results further and showed that increasing perceived outgroup knowledge reduced threat appraisals and anxiety expectancies individuals had about engaging in an intergroup interaction and indirectly reduced their desire to avoid the interaction. Study 4 found evidence supporting the idea that provision of actual—as opposed to perceived—resources that individuals could use in intergroup interactions may reduce how threatening intergroup interactions are perceived to be. Study 5 attempted to extend the results from Study 4 by directly manipulating actual resources. Psychoeducation material on strategies and techniques that have been found by previous empirical studies to improve intergroup interactions was devised in Study 5 and were presented to participants in interaction contexts. It was found that psychoeducation material reduced threat appraisals, anxiety expectancies, and desire to avoid interaction in intergroup interaction scenario compared to same-group interaction scenario. However, these positive effects of psychoeducation did not extend to anticipated intergroup interactions in Study 6. Implications of the results for intergroup relations are discussed.
