Attribution theory mainly solves how people find the causes of events in their daily lives. Hyde believes that people have two strong motives: one is to form a consistent understanding of the surrounding environment; The second is the need to control the environment. In order to meet these two needs, ordinary people must attribute others' behavior and predict others' behavior through attribution. Only in this way can they meet the need of "understanding and controlling the environment". Therefore, ordinary people, like psychologists, try to explain behavior and find causality from it, but there is no scientific method for ordinary people's attribution, and more depends on understanding and introspection. This attribution activity of ordinary people is called naive psychology by Hyde, and accordingly, Hyde is also called naive psychologist.
