Which term best describes creating an oversimplified image of a particular group of people?

The term that best describes creating an oversimplified image of a particular group of people is stereotyping. Stereotyping involves attributing specific characteristics, behaviors, or traits to an entire group based on limited or superficial information. This can lead to preconceived notions and biases, as it disregards individual differences within the group.

Stereotypes often stem from societal norms, media representations, or personal experiences, and they can reinforce harmful attitudes or beliefs. While labeling, assumption, and generalization may involve some degree of categorization or simplification, stereotyping specifically implies a reductionist view that does not accurately reflect the complexity and diversity of individuals within that group. Therefore, stereotyping captures the essence of oversimplification in the context of group identities.
