_____ is the mental process of classifying people into groups on the basis of their shared characteristics.
Misha Larkins [42]

Answer:

SOCIAL CATEGORIZATION

EXPLANATION:

Social Categorization is the process of classifying people into groups based on similar characteristics, whether it be nationality, age, occupation, diagnosis, or some other trait.

Social categorization is a natural part of social perception; it provides a mental shortcut in that it allows us to infer properties about a person based on the properties of others in the same category.

The main adaptive function of social categorization is that it permits and constrains otherwise chaotic inductive inferences.
