Openness and Intellect differentially predict Right-Wing Authoritarianism

The Big Five factor of Openness/Intellect has shown a robust relationship with Right-Wing Authoritarianism (RWA) across multiple studies, but few have investigated the relative contribution of the Big Five Aspects of Openness and Intellect, with mixed findings. The present correlational study of 304 participants expands previous research by using a multi-dimensional measure of authoritarianism that resolves methodological concerns regarding prior RWA scales. Specifically, structural equation modelling indicated that Openness had a direct effect on the RWA subscales of Conservatism, Authoritarianism and Traditionalism, whilst Intellect had a direct effect on Traditionalism as well as an indirect effect on both Traditionalism and Authoritarianism via Dangerous World Perception. Additionally, the RWA subscales fully mediated the relationship between the personality variables and prejudice towards Dissident and Dangerous groups. Conservatism predicted prejudice towards Dissident groups, whilst Authoritarianism predicted prejudice towards Dangerous groups. The findings are discussed with reference to potential mechanisms underlying these relationships.
