Community-level diversity decreases authoritarianism by alleviating dangerous and competitive worldviews: A multilevel SEM of the Dual Process Model

Scholars have long-debated the impact that living in diverse communities has on intergroup relations. Factors that mediate the relationship between macro-level diversity and micro-level indicators of tolerance, however, are rarely assessed. Based on Duckitt’s (2001) Dual Process Model of Ideology and Prejudice, we argue that community-level diversity should negatively correlate with right-wing authoritarianism (RWA) and social dominance orientation (SDO) by reducing dangerous and competitive worldviews, respectively. Using a national sample of New Zealand-born Europeans (N = 11,008), we show that dangerous worldviews predict RWA better than competitive worldviews, whereas competitive worldviews predict SDO better than dangerous worldviews (at the within- and between-levels of analysis). Critically, community-level diversity had specific negative indirect effects on between-level variability in RWA and SDO via reductions in dangerous and competitive worldviews, respectively. Thus, living in diverse communities can promote intergroup tolerance by alleviating the perception that the world is a dangerous and competitive place.
