Grounded in the theoretical framework of the dual-process motivational model of ideology and politics, we investigated the mediational role of RWA and SDO on the relationship between voting for populist parties and conspiracy beliefs; the moderation of political interest was also explored. Collapsing different convenience samples gathered after the European election (2014/2015) and the General National Election (2018/2019) allowed us to analyse two datasets (Study 1, n = 4141; Study 2, n = 2301). We hypothesised that populist voters would report higher conspiracy beliefs, RWA, and SDO, compared to non-populist voters and abstainers, and that populist voters would report more conspiracy beliefs through indirect pathways running through RWA and SDO. Furthermore, we hypothesised that such direct and indirect associations would be stronger for individuals with high rather than low political interest. Analyses of variance and moderated mediation models mostly confirmed our expectations, although RWA, and not SDO, mediated the relationships in the expected directions.
