Final answer:
An exaggerated description applied generally to every person in a category of people is known as a stereotype. Stereotypes are oversimplified generalizations that often lead to prejudice and discrimination, and are reinforced by confirmation bias.
Step-by-step explanation:
An exaggerated description that somebody applies to every person in a category of the population is referred to as C. A stereotype. Stereotypes are oversimplified generalizations about groups of people that do not take individual differences into account. While they can sometimes be positive, more often they are negative and can lead to prejudiced attitudes and discriminatory actions. For instance, believing that all older adults are slow and incompetent is a stereotype because it overgeneralizes this trait to an entire group without considering individual variations.
Stereotypes are persistent and can be subject to confirmation bias, which reinforces the stereotype when evidence appears to support it, even if contradictory evidence is more significant. This can lead to prejudice (negative feelings toward a group) and discrimination (negative actions toward individuals based on group membership), and in extreme cases, it forms the basis for racism - the belief in the superiority or inferiority of races.
