A(n) is a generalization about a group's characteristics that does not consider any individual differences.

The term you're looking for is "stereotype." A stereotype is an oversimplified and generalized belief or idea about a particular group of people. These generalizations can relate to various characteristics such as race, gender, profession, and other attributes.

Stereotypes often fail to acknowledge the individuality of people within the group, leading to misconceptions and biases. For example, if a stereotype asserts that a specific gender is not good at mathematics, it ignores the actual abilities and achievements of individuals within that gender.

It's important to recognize that stereotypes can be harmful because they often perpetuate prejudice and discrimination. Social psychology studies the effects and origins of stereotypes and emphasizes the need to consider individuals as unique, diversified beings rather than merely members of a group. By challenging stereotypes, we can foster a more inclusive and understanding society.
