What Drives Belief in COVID-19 Conspiracy Theories? Examining the Role of Uncertainty, Negative Emotions, and Perceived Relevance and Threat

Abstract

As conspiracy theories around COVID-19 pose a big global challenge to public health and well-being, this study seeks to identify how and when people are likely to activate conspiratorial thinking and believe in conspiracy theories about the coronavirus. Based on a U.S. national two-wave survey (W1: <i>N</i> = 1,119; W2: <i>N</i> = 543), this study found partial support for direct effects of uncertainty on conspiratorial thinking and support for indirect effects through threat perception. We also found some evidence of direct effects of uncertainty on conspiracy beliefs and indirect effects through threat perception and serially mediated through threat perception and negative emotions. Findings suggest that effects - either direct or indirect - of uncertainty on conspiratorial thinking/conspiracy beliefs are moderated by perceived relevance to COVID-19, personal experience of the disease, and social media use. Theoretical and practical implications of these findings are discussed.
