What are generalizations called that assume all members of a particular group are the same?

The term that refers to generalizations assuming all members of a particular group are the same is "stereotypes." Stereotyping involves oversimplified and widely held beliefs about a group of people, often leading to inaccurate representations and unjust prejudgments. This concept is significant because it can influence social attitudes, behaviors, and perceptions towards individuals based solely on their group identity rather than on their unique characteristics or experiences.

When examining other terms, assumptions can relate to beliefs that might not be universally valid but do not inherently imply an oversimplification of a group. Biases refer to prejudices or predispositions toward a certain view that typically involve an unfair preference or aversion, while clichés are overused phrases or ideas that may not necessarily apply to group characteristics but rather to expressions, reducing their originality and impact. Understanding the specific context of stereotypes helps clarify the implications they have in social interactions and cultural perceptions.
