How threat perceptions relate to learning and conspiracy beliefs about COVID-19: Evidence from a panel study.

According to appraisal theory, individuals cope with perceived threats in different ways. If engaging in problem-focused coping, for example, they may seek information useful for eliminating the root cause of the threat. However, during crises such as the COVID-19 pandemic, people tend to navigate complex information environments marked by high levels of uncertainty.
