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.

COVID-19 conspiracy theories emerged almost immediately after the beginning of the pandemic, and the number of believers does not appear to decline. Believing in these theories can negatively affect adherence to safety guidelines and vaccination intentions, potentially endangering the lives of many. Thus, one part in successfully fighting the pandemic is to understand the antecedents and consequences of COVID-19 conspiracy beliefs, which are here presented in a rapid review summarizing research from more than 28 countries. We evaluate the contribution of individual difference variables (demographic variables, personality traits, coping with threat and uncertainty), beliefs, biases, and attitudes (epistemically suspect beliefs, thinking styles and cognitive biases, attitudes towards science), and social factors (group identities, trust in authorities, social media) to COVID-19 conspiracy theories. We discuss the consequences of COVID-19 conspiracy beliefs in regard to safeguarding behaviours (hygiene, distancing, and mask-wearing), self-centred (hoarding) and misguided behaviours (pseudoscientific practices), vaccination intentions, mental health and negative social consequences (e.g., discrimination and violence). Differences between countries as well as various conspiracy theories are considered. Summarising, we suggest that belief in COVID-19 conspiracy theories is boosted by low levels of trust in a context of threat and low levels of comprehensive, accessible information in a context of uncertainty and unknowns. We conclude that research is urgently needed to address potential interventions to (re-)establish trust and provide accessible information about COVID-19.

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.
