Relationships between Dark Tetrad traits and beliefs in conspiracy theories: Mediation effects of cognitive styles

The aim of this study was to investigate the direct effects of the Dark Tetrad traits on beliefs in conspiracy theories as well as the indirect effects via rational and experiential cognitive styles. The study included 259 participants from the community population in Serbia. The results showed direct positive effects of Machiavellianism, primary psychopathy, and secondary psychopathy on conspiracy beliefs. Furthermore, only the rational cognitive style showed a significant mediation role, but the direction of its effect depends on the specific dark trait. Machiavellianism, primary psychopathy, secondary psychopathy, and narcissistic rivalry had an indirect effect on belief in conspiracy theories through a lower tendency toward rational style, while narcissistic admiration had an indirect effect through a higher tendency toward rational style. Surprisingly, the experiential cognitive style did not emerge as a significant mediator.
