Prior research indicates that far-right political groups tend to be disproportionately composed of and supported by white people. Drawing off the group identity and developmental literature, we add theoretical clarity to this relationship. We argue that a salient white racial identity motivates people to explore social contexts that affirm the value of being white. Many of these contexts (e.g., conservative media) reinforce and instill beliefs in conspiracies, perceptions of racial threat, and a legitimization of group hierarchies, which are defining features of far-right ideologies. As people develop a strong white racial identity, they should thus view far-right groups more favorably. Drawing off survey data from a national US sample of 903 white young adults, we tested a mediation model positing that the effects of a strong white racial identity with support for four far-right groups (the January 6 protesters, QAnon, the Proud Boys, and the Oath Keepers) would be mediated by enhanced levels of conspiratorial ideation, perceived racial threat, and social dominance orientation. We found that the effects of white racial identity with support for all four groups were mostly or completely accounted for by these three mediating factors. We discuss the implications of this research for the racial identity and far-right groups literatures.
