To what extent might intergroup contact interventions have a positive effect on individuals who dehumanise immigrants? Dehumanization is the psychological process of denying humanness to outgroup members and it has far reaching consequences for intergroup relations (Kteily & Landry, 2022). Prior studies have looked into other prejudice related variables such as diversity beliefs, social dominance orientation and authoritarianism, and reported that individuals most predisposed to prejudice, might also be the ones who benefit the most from intergroup contact interventions. The current studies investigated whether individuals who dehumanize immigrants the most might be able to support them after imagined contact. In particular, we took into account political ideology as a potential moderator. Considering the possibility that dehumanizing tendencies might be rooted in different political ideologies it is important to understand the impact of interventions (positive imagined contact) on intergroup relations. The results of two experiments (N = 671) with U.S. citizens in relation to two outgroups—Muslim immigrants in Experiment 1 and Mexican immigrants in Experiment 2—consistently showed that imagined positive contact condition (vs. a no contact condition) influenced intergroup support (i.e., in both experiments) and positive emotions (i.e., in Experiment 2) more for individuals who endorsed a conservative ideology and scored high for dehumanizing immigrants. Participants’ willingness to attribute positive emotions to outgroup members ultimately explained the observed effects. In this research, we discuss the theoretical and practical implications of these findings for intergroup relations and outgroup dehumanization.
