"This report takes stock of the early behavioural sciences literature on COVID-19 misinformation. Specifically, it addresses the following three main questions: (1) Who was most likely to believe or share COVID-19 misinformation? (2) What were the consequences of being exposed to or believing COVID-19 misinformation? (3) Which behavioural policy interventions were effective in countering COVID-19 misinformation? In addition to addressing these core questions, the report also provides a snapshot of the narratives of COVID-19 misinformation and the prevalence and spread of this misinformation. The report provides insights into policies that can help foster societal resilience against misinformation beyond the specific case of COVID-19, thereby contributing to policy preparation for future crises."
