Final answer:
A stereotype is a simplified and negative generalization about a group that ignores individual differences, while prejudice refers to negative attitudes and discrimination to actions against individuals based on their group membership.
Step-by-step explanation:
A stereotype is a simplified and standardized conception or image attributed to a person or group of people, often assuming a negative impression that fails to recognize individual differences. Within any given society, stereotypes tend to circulate about various groups based on race, gender, sexual orientation, ethnicity, and numerous other characteristics. Despite sometimes being positive, especially when directed towards one's own group, stereotypes are more commonly negative, leading to an imprecise and often prejudicial view of others. For example, a stereotype might lead to the assumption that all people of a certain age are incompetent, ignoring the reality that many individuals within that group might be quite capable and skilled.
Understanding and recognizing stereotypes is crucial before discussing related concepts like prejudice, discrimination, and racism. Prejudice involves negative thoughts and feelings towards someone based on group membership, whereas discrimination entails actions taken against an individual for the same reason. Racism, more specifically, involves prejudicial attitudes and discriminatory behaviors based on the belief that one race is inherently superior or inferior to others.
