This document discusses stereotyping, including its definition, sources, and consequences. Stereotyping is judging others based on group characteristics rather than seeing them as individuals. Sources of stereotyping include social learning from parents and peers as well as cognitive biases like categorizing others and favoring one's own group. Consequences of stereotyping include influencing perceptions and behaviors, confirming stereotypes through self-fulfilling prophecies, and creating prejudice, discrimination, and denial of opportunities. Teachers are encouraged to avoid promoting stereotypes, get to know students as individuals rather than labels, and use techniques like contact between groups and education to reduce stereotyping.
