Cognitive ability, right-wing authoritarianism, and social dominance orientation: A five-year longitudinal study amongst adolescents

We report longitudinal data in which we assessed the relationships between intelligence and support for two constructs that shape ideological frameworks, namely, right-wing authoritarianism (RWA) and social dominance orientation (SDO). Participants (N = 375) were assessed in Grade 7 and again in Grade 12. Verbal and numerical ability were assessed when students entered high school in Grade 7. RWA and SDO were assessed before school graduation in Grade 12. After controlling for the possible confounding effects of personality and religious values in Grade 12, RWA was predicted by low g ([3=.16) and low verbal intelligence ((3=.18). SDO was predicted by low verbal intelligence only ((3=.13). These results are discussed with reference to the role of verbal intelligence in predicting support for such ideological frameworks and some comments are offered regarding the cognitive distinctions between RWA and SDO.
