Which term describes a fixed or oversimplified idea of a person?

The term that describes a fixed or oversimplified idea of a person is "stereotype." This concept embodies a generalized belief or judgment about a particular group of people, often leading to inaccurate or exaggerated perceptions. Stereotypes can be based on various factors, including race, gender, occupation, or other characteristics, and they typically do not account for individual differences.

In contrast, archetypes refer to universal symbols or themes found across cultures and literature that embody specific human experiences or traits, while prototypes are original models that serve as a basis for other forms, and myths often involve traditional stories that explain natural phenomena or cultural beliefs. Understanding the distinction between these terms clarifies why "stereotype" is the most accurate choice for describing a fixed or oversimplified idea of a person.
