According to realistic conflict theory, what triggers prejudice and discrimination?

Realistic conflict theory posits that prejudice and discrimination arise primarily from competition between groups over limited resources. This theory emphasizes that when two or more groups vie for the same resources, such as jobs, land, or wealth, it leads to heightened intergroup tensions and hostility. The competition can foster negative perceptions and attitudes toward the rival group, which are expressed through prejudice and discriminatory behaviors.

For instance, when groups perceive each other as threats to their access to valuable resources, they are likely to view each other with suspicion or animosity, reinforcing stereotypes and leading to discriminatory practices. This dynamic illustrates how external factors—specifically, competition over tangible resources—serve as catalysts for intergroup conflict and can exacerbate divisions within society.
