A study investigating the impact of COVID-19 misinformation on hypothetical demand (i.e., willingness-to-pay) for an unproven treatment and propensity to spread misinformation online among US adults (N=678) found that prior exposure to misinformation increased misinformation promotion by 18%. The study tested two interventions to counteract the misinformation: a tentative or “diplomatic” refutation based on materials used by health authorities and an enhanced refutation developed from psychological research that explains why the information is false and provides factual information to replace it. Both tentative and enhanced refutations reduced demand (by 18% and 25%, respectively) as well as misinformation promotion (by 29% and 55%).
