Upholding social hierarchies: Social dominance orientation moderates the link between (intergroup) conspiracy exposure and violent extremism

Abstract

Across two experimental studies, we explored whether exposure to intergroup conspiracy theories can increase violent reactions towards targeted groups. We also examined how ideological attitudes may moderate the effect. In Study 1 ( N = 160, preregistered), we found that exposure to immigrant conspiracy theories (vs. control) increased the willingness to use violence for those who reported higher social dominance orientation (SDO) and right-wing authoritarianism (RWA). Study 2 ( N = 211, preregistered) sought to extend these results by focusing on a specific target: Muslim immigrants. Exposure to Muslim immigrant conspiracy theories (vs. control) increased motivation and willingness to use violence for those with higher SDO (but not RWA). These findings showcase how exposure to intergroup conspiracy theories and violent reactions are conditional on specific ideological attitudes. Thus, when considering interventions, we argue that it is crucial to consider the role of ideological worldviews when seeking to combat conspiracy-inspired violence.
