Across two studies, we demonstrated that support for group-based hierarchies differentially affects evaluation of ingroup and outgroup criminal offenders and that this effect generalizes to overall evaluations of their respective groups. Drawing on social dominance theory, our results show that differential judgments of national ingroup and immigrant outgroup offenders reflect hierarchy regulating strategies. Study 1 (N=94) revealed that egalitarians (low on SDO) were more lenient toward outgroup offenders and their ethnic group (Arab immigrants) when compared to ingroup offenders and their national group (Swiss citizens). The opposite was true for social dominators (high on SDO). Study 2 (N=88) replicated the results of Study 1 and further demonstrated that the socio-economic status of the perpetrator did not affect perpetrator group evaluations suggesting that the arbitrary sets of ethnicity or nationality, not education level and employment status, were the important cues for hierarchy-regulating judgments of criminal offender
