Does Length Matter? The Impact of Fact-Check Length in Reducing COVID-19 Vaccine Misinformation

ABSTRACTThis study examines the impact of message length and audience's perceived information overload on the effectiveness of a fact-check in reducing belief in fake news within the COVID-19 vaccination context. Through an online experiment (N = 374) conducted in Singapore, we found an interaction effect between one's level of information overload and the type of fact-check that was being shown (short, medium, or long). The findings from this study help to extend the literature on the effectiveness of fact-checks in reducing general public's belief in fake news.
