Sadness, Risk Direction, and Correction of Health Misinformation: Effects on Beliefs and Sharing Intentions

= 797), participants viewed a misinformation post, completed an autobiographical emotion induction and then received a text-only correction. Corrections reduced belief in false claims and lowered sharing overall. Sadness had no main effect but interacted with risk direction: in the risk-increasing e‑cigarette condition, sadness was associated with larger belief reductions, whereas in the risk-decreasing vaccine condition, sadness attenuated belief reduction. Belief predicted sharing intention, and the only reliable pathway from sadness to sharing operated indirectly via belief in the risk-decreasing condition. The findings highlight risk direction as a structural property of corrective messages and show that sadness can support or undermine corrections, depending on how risk is repositioned.
