Final answer:
A stereotype is a broad oversimplification about a group of people, not accounting for individual differences, and can contribute to prejudice and discrimination. These generalizations are often based on aspects such as race and ethnicity, and the confirmation of stereotypes through selective observations can reinforce prejudiced beliefs and actions.
Step-by-step explanation:
A stereotype is an oversimplified and often negative generalization about a group of people, attributing certain traits to them without regard for individual differences. These can relate to any aspect of human difference, including race, ethnicity, age, gender, sexual orientation, and can lead to assumptions that all members of a group are the same. Stereotypes arise from existing societal beliefs and are perpetuated by confirmation bias, which is when incidents that seem to support the stereotype are given undue weight, whereas evidence to the contrary is dismissed or overlooked.
Prejudice, discrimination, and racism are related but distinct concepts. Prejudice involves preconceived opinions and feelings, discrimination entails actions based on prejudices, and racism is a form of prejudice based on the belief of the inherent superiority of one race over others. Stereotypes often lead to prejudices and discriminatory behaviors, negatively impacting individuals and groups by promoting unequal treatment and social injustice.
