HEXACO, social worldviews and socio-political attitudes: A mediation analysis

The Dual Process Model of Ideology and Prejudice states that ‘dangerous world’ and ‘competitive jungle’ beliefs shape Right Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO), respectively. We investigated whether the associations of the HEXACO personality traits with SDO and RWA were mediated by these beliefs. Study 1 (297 Italian participants) investigated mediation at the general factor level. Study 2 (344 US participants) focused on the components of Honesty and Humility and of Openness-culture and Openness-curiosity. Personality associations with SDO were mostly mediated by Competitive Jungle beliefs, whilst personality associations with RWA were mostly unmediated. At the level of narrow trait components, different effects for Honesty and Humility and for Openness-culture and Openness-curiosity were revealed.

► The HEXACO effects on dangerous and competitive beliefs were examined.
► Honesty–Humility was the main associate of dangerous and competitive beliefs.
► Honesty and Humility effects on RWA and SDO were in opposite directions.
► Openness showed mainly direct effects on RWA and SDO.
