Societal crises and stressful events are associated with an upsurge of conspiracy beliefs that may help people to tackle feelings of lack of control. In our study ( N = 783), we examined whether people with higher feelings of anxiety and lack of control early in the COVID‐19 pandemic endorse more conspiracy theories. Our results show that a higher perception of risk of COVID‐19 and lower trust in institutions' response to the pandemic were related to feelings of anxiety and lack of control. Feeling the lack of control, but not anxiety, independently predicted COVID‐19 conspiracy theory endorsement. Importantly, COVID‐19 conspiracy beliefs were strongly correlated with generic conspiracy and pseudoscientific beliefs, which were likewise associated with the feeling of lack of control and lower trust in institutions. The results highlight that considering people's emotional responses to the COVID‐19 pandemic is crucial for our understanding of the spread of conspiracy and pseudoscientific beliefs.

We examined whether scientific reasoning is associated with health-related beliefs and behaviors over and above general analytic thinking ability in the general public ( N = 783, aged 18–84). Health-related beliefs included: anti-vaccination attitudes, COVID-19 conspiracy beliefs, and generic health-related epistemically suspect beliefs. Scientific reasoning correlated with generic pseudoscientific and health-related conspiracy beliefs and COVID-19 conspiracy beliefs. Crucially, scientific reasoning was a stronger independent predictor of unfounded beliefs (including anti-vaccination attitudes) than general analytic thinking was; however, it had a more modest role in health-related behaviors.
