Depending on how involved parties appraise day-to-day conflicts, they either may feel angry or contemptuous toward the other party, which, in turn, may result in stronger confronting or avoiding intentions. In this paper we investigated how the content of stereotypes associated with the group to which an outgroup perpetrator belongs affects appraisals, emotions, and behavior. In two experiments, we demonstrated that stereotyping an outgroup as less warm resulted in increased feelings of anger, and tendencies to react forcefully toward an outgroup party in a conflict. Specifically, this effect of low stereotype warmth was explained by increased appraisals of negative intentions. Stereotyping an outgroup as less competent in the same situation elicited increased feelings of contempt, and tendencies to avoid an outgroup party in a conflict. This effect of stereotype incompetence was due to decreased appraisals of control over the other party.
