The fundamental attribution error (FAE)occurs when we underestimate the influence of internal factors and overestimate the influence of external factors when we evaluate others' behaviors.

Fundamental Attribution Error

The tendency for observers, when analyzing another's behavior, to underestimate the impact of the situation and to overestimate the impact of personal character or intent.

Internal Factors

refers to influences originating within an individual, such as beliefs, attitudes, and personal motivations, affecting their behavior and actions.
