Dim minds and dark attitudes.

This study of Hodson and Busseri on a United Kingdom and U.S. datasets documents the (hardly surprising) correlation between lower cognitive ability and right-wing ideology. They suggest that right-wing ideologies which are socially conservative and authoritarian represent a mechanism through which cognitive ability is linked with prejudice.
Despite their important implications for interpersonal behaviors and relations, cognitive abilities have been largely ignored as explanations of prejudice. We proposed and tested mediation models in which lower cognitive ability predicts greater prejudice, an effect mediated through the endorsement of right-wing ideologies (social conservatism, right-wing authoritarianism) and low levels of contact with out-groups. In an analysis of two large-scale, nationally representative United Kingdom data sets (N = 15,874), we found that lower general intelligence (g) in childhood predicts greater racism in adulthood, and this effect was largely mediated via conservative ideology. A secondary analysis of a U.S. data set confirmed a predictive effect of poor abstract-reasoning skills on antihomosexual prejudice, a relation partially mediated by both authoritarianism and low levels of intergroup contact. All analyses controlled for education and socioeconomic status. Our results suggest that cognitive abilities play a critical, albeit underappreciated, role in prejudice. Consequently, we recommend a heightened focus on cognitive ability in research on prejudice and a better integration of cognitive ability into prejudice models.

    When childhood IQ tests show that certain ethnic minorities consistently underperform, invariably we conclude that the tests must somehow be flawed.

    When childhood IQ tests show that social conservatives underperform, invariably we conclude that the tests are accurate and just confirming what we already knew anyway.
