Second, studies that focus on psychological factors pay attention to people’s psychological content and ways of thinking. According to Stempel et al. ([15], p. 354), a more psychological approach supports the existence of a conspiratorial personality or paranoid style of thought and views conspiracy theories as closely related to scapegoating and “us versus them” worldviews. In addition, Goertzel [4] puts forth the concept of a monological belief system in which similar beliefs comprise a self-sealing and expanding network of ideas that mutually support each other. Some conspiracy beliefs are correlated with each other as part of a monological belief system. Psychologists stress the psychological antecedents of conspiracy beliefs and have studied motivation, cognition, and personality as influencing factors. For example, from a psychological perspective, conspiracy theories help to satisfy people’s motivations. Douglas et al. [12] explain that these social-psychological motives include (1) the epistemic desire for understanding, accuracy, and subjective certainty; (2) the existential motive for control and security; and (3) the social motive to maintain a positive image of the self or group. In addition, the psychological approach emphasizes cognitive aspects of conspiracy theories. Miller [19] argues that conspiracy theories essentially play two cognitive roles: the argumentative and social critique roles. Moreover, Swami et al. [17] show that beliefs in conspiracies related to 9/11 are positively related to the Big Five personality factor, e.g., agreeableness.
