Whites' racial identity centrality and social dominance orientation are interactively associated with far-right extremism

This paper presents evidence from five studies (total White N = 7,209) that White American's racial identity centrality is related to self-reported levels of far-right extremism. Furthermore, evidence from two of the studies shows that social dominance orientation (SDO) is another robust predictor of far-right extremism. Results also show that SDO can moderate the relationship between White identity and extremism such that the association is stronger for Whites with a higher level of SDO. Therefore, evidence suggests that the role of Whites' racial identity centrality is particularly relevant, and SDO is an important variable that may moderate the association between Whites' racial identity centrality and their far-right extremism in the contemporary political era.
