Does COVID-19 Message Fatigue Lead to Misinformation Acceptance? An Extension of the Risk Information Seeking and Processing Model.

Based on the Risk Information Seeking and Processing Model, the present study examines whether COVID-19 message fatigue leads to greater information avoidance and heuristic processing, and consequently greater acceptance of misinformation. We conducted a survey of 821 Korean adults regarding their information seeking and processing regarding COVID-19 vaccination. Results of SEM analyses showed that COVID-19 message fatigue was (a) negatively related to information insufficiency and (b) positively related to information avoidance and heuristic processing. Information avoidance and heuristic processing were subsequently related to greater levels of misinformation acceptance. Theoretical and practical implications are discussed.
