Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
AMA RI - B- B - R
Respondents will be randomized to an AMA statement acknowledging racial injustice read by an African American individual. The messenger / doctor in the follow-up AMA videos will also be African American - the message on Covid-19 will include information on the disproportionate impact on communities of color.
Acknowledgement Racial Injustice AMA
Investigators will examine whether acknowledgements of racial inequality are helpful towards improving knowledge retention and behaviors associated with the intervention among participants. In this arm, participants will receive a AMA statement on racial injustice.
African American Sender Acknowledgement
Investigators will also vary the messenger of the acknowledgement sender. In this arm participants receive a African American sender in acknowledgment of AMA
