Unvaxxed and unafraid: Unvaccinated Americans perceive less disease risk than do vaccinated Americans

Is disease risk perception accurately calibrated among the unvaccinated? People shift their attitudes to rationalize choices, so those who choose be unvaccinated may motivated feel less at risk. In three studies (total N = 1446), we asked Americans how worried they were about catching/spreading influenza and COVID-19 whether vaccinated against diseases. Unvaccinated participants felt of diseases than participants. For instance, ∼24% had ∼28% stronger intention engage in activities that carried a high transmission (Study 3). Overall, most vulnerable act least vulnerable.
