Objective: We sought to replicate and extend provisional research on the personological correlates of conspiracy beliefs by examining their associations with abnormal- and normal-range personality domain-level traits and, for the first time, lower-order personality facets; we also examined internalizing symptoms.
Method: The study comprised four samples of community and student participants (N = 1,927), and examined the cross-sectional relations between self-reported conspiratorial ideation and measures of (a) the six-factor model of general personality, (b) intellectual humility (IH), (c) traits relevant to certain personality disorder features (narcissism, psychopathy, disinhibition), and (d) internalizing symptoms (depression, anxiety, anger).
Results: Agreeableness and conscientiousness were significant, albeit modest, negative correlates of conspiracy beliefs, although other general personality dimensions tended to manifest negligible associations.
