What is the term for a socially shared belief about a group of people that can be positive or negative?

The term that describes a socially shared belief about a group of people, which can be either positive or negative, is stereotype. Stereotypes are oversimplified and generalized perceptions that people have about members of a particular group, often based on characteristics such as race, gender, or occupation. These beliefs can shape how individuals perceive and interact with others, influencing social dynamics and interpersonal relationships.

In contrast, prejudice refers to an unfavorable or hostile attitude toward a person or group, typically based on stereotypes. It usually connotes a negative bias rather than a neutral or positive belief about the group as a whole. Discrimination involves actions taken against individuals or groups based on their perceived characteristics, aligning closely with prejudiced attitudes but focusing on behavior rather than belief systems. Norms represent the accepted standards and rules governing behavior within a society or group, which are not directly related to beliefs about specific groups of people.

Thus, the correct term for a socially shared belief about a group of people is indeed stereotype.
