The impact of the HEXACO personality model in predicting socio-political attitudes: The moderating role of interest in politics

In this paper, the relationships between the HEXACO personality model and socio-political attitudes were investigated. It was hypothesized that the relationship between Honesty–Humility and Social Dominance Orientation (SDO) and that between Openness and Right Wing Authoritarianism (RWA) were moderated by interest in politics. Three hundred and forty-four individuals participated in the study. Results showed that Honesty–Humility affected SDO and Openness affected RWA more strongly among individuals with a higher level of interest in politics. Facet-level analyses revealed that Humility and Experiential Openness were uniquely connected to ideology. These effects were also moderated by interest in politics.

► Associations of the HEXACO personality factors with sociopolitical attitudes.
► Openness is related to low Right-Wing Authoritarianism (RWA).
► Honesty–Humility is related to Social Dominance Orientation (SDO).
► The relations are stronger among persons who are interested in politics.
► Humility facets are uniquely connected with SDO, Experiential Openness facets with RWA.
