Conspiracy Endorsement as Motivated Reasoning: The Moderating Roles of Political Knowledge and Trust

Given the potential political and social significance of conspiracy beliefs, a substantial and growing body of work examines the individual-level correlates of belief in conspiracy theories and general conspiratorial predispositions. However, although we know much about the psychological antecedents of conspiracy endorsement, we know less about the individual-level political causes of these prevalent and consequential beliefs. Our work draws from the extant literature to posit that endorsement of conspiracy theories is a motivated process that serves both ideological and psychological needs. In doing so, we develop a theory that identifies a particular type of person-one who is both highly knowledgeable about politics and lacking in trust-who is most susceptible to ideologically motivated conspiracy endorsement. Further, we demonstrate that the moderators of belief in conspiracy theories are strikingly different for conservatives and liberals.
