We encountered a disagreement in the literature related to this topic between whether agreeableness was a predictor of conspiracy beliefs or not. The purpose of our study was to determine whether interpersonal trust was a better predictor of conspiracy beliefs than agreeableness, the big five personality that trust is a part of. Our results supported this hypothesis, as trust was significantly correlated with conspiracy beliefs while agreeableness was not.
