Stereotypes, prejudice, and discrimination shape social interactions and perceptions. These interrelated concepts can lead to social inequality and marginalization. Stereotypes are oversimplified beliefs about groups, while prejudice involves negative attitudes based on stereotypes. Discrimination is the behavioral manifestation of prejudice. Understanding the roots and consequences of these phenomena is crucial for promoting social justice. They can arise from various sources, including social influences, evolutionary tendencies, and cognitive processes. Cognitive biases, such as confirmation bias and fundamental attribution error, contribute to their maintenance and perpetuation.
