Trait theory

Trait theory is a way of thinking about what makes people different from one another. It is based on the idea that everyone has a unique set of characteristics or "traits" that help them to behave and think in different ways. For example, one person may be optimistic and outgoing, while another person might be anxious and more introverted. Trait theory suggests that these different traits can help us understand why people behave the way they do.
