Current thinking about conspiracy theories is dominated by epistemological and psychological approaches. The former see the study of conspiracy theories as a branch of epistemology and insist that each theory should be judged on its evidential merits. On this account, a conspiracy theory is an explanation of an event which cites a conspiracy as a salient cause. Psychological approaches explain belief in conspiracy theories by reference to individual personality traits and generic cognitive biases. Despite their popularity, both epistemological and psychological approaches are flawed. After identifying their flaws, a case is made for a different perspective which focuses on the political function of conspiracy theories. A conspiracy theory is not just an explanation of an event which cites a conspiracy as a salient cause. Conspiracy theories have a range of additional features which distinguish them from ordinary theories about conspiracies and make them unlikely to be true. The political approach sees many conspiracy theories as forms of political propaganda and is especially mindful of the role of conspiracy theories in promoting extremist ideologies.
