CURBING
This study demonstrated the applicability of the inoculation theory to COVID-19-related misinformation with an online priming study and randomized control trial, with the latter applying a game-based intervention to provide practical experience in curbing the effects of an infodemic. This study also extends our understanding of the mechanisms underlying the effectiveness of the inoculation theory, depicting that the inoculation intervention enhances misinformation discrimination by improving persuasion knowledge at the individual level. Accordingly, it provides empirical grounding for the hypothesis on the effects of broad-spectrum inoculation interventions.
