Homegrown stereotypes are generalizations that groups develop about their own –typical characteristics. They are a distinct class of in-group stereotypes in the contexts and processes that give rise to them, as well as in their consequences for individual group members. The authors develop the concept of homegrown stereotypes and locate the origins of these stereotypes in self-presentation processes. They discuss the accuracy of these stereotypes and consider their similarities to and differences from a number of related phenomena. An examination of homegrown stereotypes highlights the importance of taking into account the impact of in-group, as well as intergroup, dynamics on the production of stereotypes.
