Reactions to group devaluation and social inequity: A comparison of social identity and system justification predictions.

System justification theory (SJT) proposes that support for social inequality should be stronger among members of devalued groups than among members of higher status groups; that embracing the system in this way soothes anger and leads to a withdrawal of support for social change; and that these effects should occur when group interest is weak. We compared these SJT predictions with identity management and hope for group advancement accounts that we deduced from social identity theory (SIT) which suggest that both system justification and support for social change will be significant when group interest is strong. Consistent with the SIT-based accounts, Study 1 (N = 116, Malaysia, M age = 19.09 years) showed that strong identifiers were more concerned about their in-group’s reputation than weak identifiers, and that this concern increased system justification but only before an out-group audience to whom a need to present one’s group in good light is normally strong. Study 2 (N = 375, Australia, M age = 23.59 years) conceptually replicated Study 1’s results and further revealed that strong identifiers justified the system due to the hope that their in-group status would improve in the future. Finally, Study 3 (N = 132, Germany, M age = 20.34 years) revealed that system justification soothed anger and reduced support for social protest but only when group interest was strong (not weak). We did not find evidence in support of SJT predictions
