Spite and science-denial: Exploring the role of spitefulness in conspiracy ideation and COVID-19 conspiracy beliefs

Science denialism is at the heart of many conspiracy theory beliefs. We propose that such beliefs are manifestations of a distal social process: spite. In three pre-registered studies, we test the hypothesis that established predictors of these beliefs (epistemic, existential, and social motives) are specific cues of competitive disadvantage that provoke a common facultative “spiteful” psychological response, making a person more open to believing in conspiracy theories. Study 1 (N = 301; UK representative Prolific sample), found that spite mediated the relationship between realistic threat and in-group narcissism (social motives), political powerlessness (existential motive), and intolerance for uncertainty (epistemic motive), and conspiracy theory belief and COVID-19 conspiracies. This pattern was replicated in Study 2 (N = 405; UK representative Prolific sample). In Study 3 (N = 405; UK representative Prolific sample), we found that those who engaged in a spite-inducing task reported higher levels of spite which indirectly resulted in stronger beliefs in conspiracy theories. The overall pattern of results provides initial evidence that spite may play a role in why people engage with false information. Research and policy implications of these findings are discussed.
