Fake news and misinformation

Abstract

This chapter explores the pervasive issue of health-related misinformation and fake news, particularly during the COVID-19 pandemic. It defines key terms, examines how misinformation spreads, and discusses its prevalence and impact on public health. The chapter highlights the role of social media in the rapid dissemination of false information and investigates the reasons behind the public’s belief in such misinformation. Consequences of believing in health misinformation are addressed, including negative impacts on health behaviors and public trust. The chapter also reviews various strategies to combat misinformation, such as debunking, nudging, and prebunking, and emphasizes the need for comprehensive approaches to strengthen individual and societal resilience. Future research directions are suggested, focusing on underexplored areas and the generalizability of findings beyond the COVID-19 context. This comprehensive analysis underscores the importance of combating health misinformation to protect public health.
