Moral foundations underlying behavioral compliance during the COVID-19 pandemic.

During the COVID-19 pandemic, government and public health officials have advocated three behaviors to help "flatten the curve" of the disease-staying-at-home, wearing face masks, and social distancing. But, some people, especially those younger in age, have flouted restrictions, harming themselves and the community. We explore the moral foundations underlying people's compliance with the three behaviors. Our study with 1033 Americans revealed that caring and fairness concerns predict complying with all behaviors, while sanctity concerns only predict compliance with wearing face masks and social distancing. A deeper investigation revealed age differences in loyalty and sanctity concerns for staying-at-home and social distancing, and in sanctity concerns only for wearing face masks. The findings document the innate intuitions that guide one's decision to comply with such behaviors. They also provide governments and policy officials with implications on possible message frames to use in communicating the importance of the three behaviors in order to protect one's and the public's health from COVID-19 and other flu-like illnesses in the future.
