People see outgroups as all alike but ingroups as varied

Evidence

Categorization exaggerates between-group differences and minimizes withingroup differences (Tajfel, 1970). Minimizing within-group differences especially occurs for outgroups. People typically see outgroups as less variable than average (i.e., as “all alike”), and to a lesser extent see ingroups as more variable than average (i.e., “we” are varied); this sets the stage for prejudgments of outgroup members (see Judd & Park, ch. 8 this volume). Sometimes ingroup homogeneity also occurs, especially for minorities and on dimensions important to one’s identity (e.g., Simon, 1992). Perceived homogeneity on either side sharpens the interpretation of differences between groups. — John F. Dovidio, Peter Glick, Laurie A.
