The main function of a scientific theory is to help describe and explain how the world works. To form a scientific theory, scientists start with a set of assumptions, then use logic and deductive reasoning to come up with hypotheses they can test. Psychologists use scientific theories to explore human thought, emotion, and behavior.

- Is Falsifiable: A theory must be capable of being proven wrong. This means it should generate testable hypotheses that can be supported or refuted by empirical evidence.
- Organizes Data: A useful theory helps to organize and make sense of existing data. It provides a framework for understanding and interpreting research findings.
- Guides Action: A good theory can inform practical applications and guide interventions. It can be used to develop effective therapies, educational programs, or public policies.
- Is Internally Consistent: A theory should be free of contradictions and logical inconsistencies. Its components should be logically connected and mutually supportive.
