Advocating for Mask-Wearing Across the Aisle: Applying Moral Reframing in Health Communication.

During the COVID-19 pandemic, the United States public polarized along political lines in their willingness to adopt various health-protective measures. To bridge these political divides, we tested moral reframing as a tool for advocating for wearing face masks when audiences vary in their moral priorities. We additionally address a gap in prior moral reframing research by comparing responses to a topic-relevant non-moral appeal. Across two studies, we examined effects on perceived message effectiveness, intentions to wear masks, support for a nationwide mask mandate, and willingness to share messages on social media. We find support for the efficacy of ideology-matched moral arguments and generally find support for the boomerang effect of ideology-mismatched moral arguments. However, these effects were restricted to relatively liberal audiences; politically conservative message recipients did not differentiate between message conditions. We discuss these asymmetric effects and their implications for theory in moral rhetoric.
