Although right-wing authoritarianism (RWA) and social dominance orientation (SDO) are the two most studied individual difference correlates of prejudice, debate remains over their status as enduring constructs that precede generalized prejudice. We contribute to this discussion using 10 annual waves of longitudinal data from a nationwide random sample of adults to investigate the stability and temporal precedence of RWA, SDO, and prejudice among members of an ethnic majority group (Ns = 23,383–47,217). Results reveal high wave-to-wave rank-order stability for RWA, SDO, and generalized prejudice. Adjusting for their between-person stability, RWA and SDO predicted within-person increases in generalized prejudice. Results replicated when predicting (a) prejudice toward three specific minority groups (namely, Māori, Pacific Islanders, and Asians) and (b) anti-minority beliefs. These findings demonstrate that RWA and SDO are highly stable over 10 consecutive years and that they independently precede within-person annual increases in generalized prejudice and anti-minority beliefs.
