Study Summary
The aim of the study is to build off results from our first experiment (NCT04371419) , and test whether messages that acknowledge racial injustice on behalf of institutions affect the retention of knowledge and movement of beliefs and behavior with respect to Covid-19. The investigators will also test the effect of concordance of providers and whether highlighting the unequal burden of the disease has additional effects on knowledge, beliefs and behavior regarding covid-19. The sample will include African American and white adult Americans and oversample those with less than a college degree.
Primary Outcome
Participants were asked to identify ways to prevent COVID-19 spread and identify four common symptoms. The incidence rate for knowledge gaps is the count of knowledge gaps divided by the maximum possible count: 10.
