The study examines whether adding a refutational ending to narrative messages improves correction effectiveness and how the effect differs depending on whether the correction message is presented before or after exposure to misinformation. A 2 (narrative format: simple vs refutational narrative) × 2 (correction placement: prebunking vs debunking) between-subjects online experiment (N = 281) with US participants was conducted to correct misinformation about human papilloma virus vaccines. The results suggested that the refutational narrative was more effective in reducing misbeliefs in prebunking, whereas the simple narrative was more effective in debunking. This interaction was further moderated by issue involvement. Theoretical and practical implications are discussed.
