A(n) is a set of generalized beliefs and expectations about a particular group and its members.

The term you are looking for is "stereotype."

Stereotypes are oversimplified and generalized beliefs about a group of people, typically based on characteristics such as race, gender, ethnicity, or occupation. These generalized beliefs can lead to expectations about individuals within that group, often portraying them in a fixed manner regardless of their unique traits or abilities.

While stereotypes can arise from attempts to make sense of a complex world, they often contribute to unfair judgments and discrimination. For example, someone might stereotype all members of a certain profession as being similar in behavior or capability, which disregards the individuality of persons within that group.

It's essential to recognize and challenge stereotypes to promote understanding and acceptance among diverse groups in society.
