One possible consequence of being the target of discrimination is internalized oppression. This occurs when people come to view and treat themselves and other members of their group in the same ways that they have been stereotyped or mistreated as targets. Many prejudice-reduction interventions are based on the idea that if people from different groups are brought together they will learn about each other, come to see their commonalities, and prejudice will diminish. Gordon Allport’s contact hypothesis outlined the specific conditions required for prejudice reduction through intergroup contact. A large number of psychological studies have focused on the characteristics of people who engage in discriminatory behavior and their cognitive processes. The term institutional racism was first introduced by Stokely Carmichael and Charles V. Hamilton in their 1967 book, Black Power. The number of refugees and other migrants across the globe has reached its highest level since World War II.
