Prejudice reduction

Theories from intergroup relations research have informed many approaches to prejudice reduction. Researchers have focused on developing theoretical frameworks for understanding how to effectively reduce intergroup conflict and prejudice. For example, a recent intervention developed by Patricia Devine and colleagues focuses on training individuals to overcome cognitive biases and reduce implicit bias. The intervention resulted in reduced implicit bias up to two months after the intervention was administered. Other prejudice reduction research has investigated intergroup interaction techniques including cooperative learning (such as Elliot Aronson's " Jigsaw Classroom ") and making group identity less salient or a superordinate identity more salient in addition to individual techniques such as encouraging perspective-taking with a member of a stigmatized group and building empathy with stigmatized groups. Another technique that has been studied to reduce prejudice through intergroup relations included sparking interest in another person's culture that was different than their own. A meta-analysis of 515 studies found that there seemed to be a connection between intergroup contact and lower levels of intergroup prejudice.
