Infrahumanization and Socio-Structural Variables: The Role of Legitimacy, Ingroup Identification, and System Justification Beliefs

Abstract

As there is a robust tendency to support system-legitimizing beliefs by appealing to stereotypes or ideologies, we examined the role played by the perception of the status quo in relation to the infrahumanization bias. We compared this bias in high versus low-status group members and tested the mediating role of system justification beliefs and ingroup identification. The results of a moderated-mediated regression model (N = 238) showed that the perception of legitimacy of one’s own status had differential effects on the infrahumanization bias: The perception of legitimacy was positively associated with the endorsement of system justification beliefs and negatively associated with ingroup identification among low-status group members, whereas the perception of legitimacy was positively associated with ingroup identification among high-status group members. In both groups, ingroup identification was positively correlated with the tendency to infrahumanize the outgroup, while the endorsement of system justification beliefs was linked to the infrahumanization among low-status group members only. The findings highlight that the Social Identity Theory and the System Justification Theory can be fruitfully combined to explain infrahumanization tendencies.
