Conspiracy Ideation and Populism

Worldviews characterizing conspiracy theories and populism present similar core beliefs suggesting shared psychological features. Both are expressed through simplified narratives with two morally well-defined sides. Populism articulates narratives implying stark oppositions of internally homogeneous groups (“People” and “élite”) and a Manichean view of these groups (élite = evil). Conspiracy ideation is defined as a general propensity to explain impactful geopolitical events through conspiracy theories, concocted by malevolent élites to the detriment of ordinary people. The present chapter provides a literature review highlighting that individual endorsement of populist attitudes and conspiracy beliefs emerge as psychological responses to threatened basic needs. Both conspiracist and populist narratives offer the alienated masses a renewed sense of certainty and control over reality, self-or-ingroup image. Furthermore, the chapter reports empirical findings about links between conspiracy beliefs and populist attitudes with ideological belief systems such as system justification, social dominance orientation, and right-wing authoritarianism. Results show positive associations of both phenomena with authoritarianism, weak or lacking associations with social dominance orientation, and negative robust relations with system-justifying tendencies. Overall, the chapter provides an integrated perspective of the shared psychosocial roots of the endorsement of political populism and conspiracy beliefs and moves around their potential applied implications.
