Simply defined, stereotypes are commonly-held beliefs about groups of people. Racial stereotypes are the widely shared perceptions that people have about certain social groups and the individuals who are members of those groups. To understand the large and growing literature on racial stereotypes, it is useful to organize this body of research by whether stereotypes are being explored as dependent variables or as independent variables. When the focus is on dependent variables, scholars investigate why racial stereotypes exist and how they work. Conversely, the work on stereotypes as independent variables emphasizes their influence on both attitudinal and behavioral outcomes. Special attention should also be paid to the stereotypes that are often applied to people who exist at the intersections of multiple racial, ethnic, gender, and sexuality groups (for example, those attributed female and non-binary persons of color).
