We investigate the role of racial group loyalty on generosity in a broadly representative sample of the U.S. adult population. We use an audiovisual presentation to manipulate beliefs about the race, income, and worthiness of Hurricane Katrina victims. Respondents then decide how to divide $100 between themselves and Katrina victims. We find no effects of victims’ race on giving on average. However, respondents who report feeling close to their racial or ethnic group give substantially more when victims are of the same race rather than another race, while respondents who do not feel close to their group give substantially less.
