This entry introduces the Common Ingroup Identity Model. In intergroup interactions, it is possible for ingroup members to make biased judgments toward both ingroup and outgroup members. People tend to evaluate ingroup members positively and outgroup members negatively. The Common Ingroup Identity Model proposes that intergroup bias can be reduced by transforming the group boundaries from “us” versus “them” into a more general “we” that include all the original in- and outgroup members.
