The carry-over effect of competition: The impact of competition on prejudice towards uninvolved outgroups

Following realistic group-conflict theory, negative interdependence between groups (e.g., competition) leads to prejudice towards the opposing outgroup. Based on research on mindset priming, it is hypothesized that competition increases prejudice, regardless of whether the derogated outgroup is involved in the competition or not. In Experiment 1, participants remembered an event involving either competition or cooperation; in Experiments 2 and 3 they participated in a competitive, cooperative, or individual assessment of their knowledge. Subsequent measures indicated that competition results in higher levels of prejudice, even when it is not related to the intergroup context. Additional evidence suggests that this effect is not driven by the transfer of negative affect or ego-depletion. Possible underlying cognitive processes are discussed.
