From news websites to social media: Unpacking the influence of online channels on presumed influence and responses to misinformation

This study employs the theoretical model of the influence of presumed influence to examine the mechanisms that drive online users to engage in information authentication and social correction, which are critical for countering misinformation. In particular, this study examines how the perceived prevalence and presumed influence of misinformation affect the intention to verify and correct misinformation, and how the use of different online platforms (i.e., social networking sites, video platforms, instant messaging applications, and news websites) for political news shapes these perceptions. This research draws on survey data from 2,589 respondents in Taiwan. The findings indicate that perceived prevalence has a positive relationship with presumed influence, which in turn, leads to authentications and corrections. Moreover, using social networking sites and video platforms for political news is positively related to perceived prevalence, whereas instant messaging applications have a negative association.
