Mitigating infodemics: The relationship between news exposure and trust and belief in COVID-19 fake news and social media spreading

INTRODUCTION: Misinformation surrounding COVID-19 poses a global public health problem that adversely affects governments' abilities to mitigate the disease and causes accidental deaths and self-harm due to false beliefs about the virus, prevention measures, vaccines and cures. We aim to examine the relationship between exposure to and trust in COVID-19 news (from Television, social media, interpersonal communication) and information sources (healthcare experts, government, clerics) and belief in COVID-19 myths and false information, as well as critical verification practices before posting on social media. METHODS: We use a cross-sectional researcher-administered phone survey of adults living in Lebanon between March 27 and April 23, 2020. RESULTS: The sample included 56.1% men and 43.9% women, 37.9% with a university degree, 63.0% older than 30, and 7% with media literacy training. Those who trust COVID-19 news from social media 95%CI:(1.05-1.52) and interpersonal communication 95%CI:(1.25-1.82), and those who trust information from clerics 95%CI:(1.25-1.82) were more likely to believe in COVID-19 myths and false information. University graduates 95%CI:(0.25-0.51) and those who trust information from government 95%CI:(0.65-0.89 were less likely to believe in myths and false information. Those who believe in COVID-19 myths and false information 95%CI:(0.25-0.70) were less likely to engage in critical social media posting practices. Only those who underwent media literacy training 95%CI:(1.24-6.55) were more likely to engage in critical social media posting practices. CONCLUSION: Higher education and trust in information from government contributed to decreasing belief in COVID-19 myths and false information. Trust in news from social media, interpersonal communication and clerics contributed to increasing belief in COVID-19 myths and false information, which in turn contributed to less critical social media posting practices, thereby exacerbated the infodemic. Media literacy training contributed to increasing critical social media posting practices, thereby played a role in mitigating the infodemic.
