Traits are stable qualities in people that have continuous dimensions and quantitative differences. Examples of traits are things like fairness, intelligence, confidence, and helpfulness. Individual differences are reflected in the amount that a trait is seen. Within trait theory, there are many different approaches to how traits operate and to what extent. A Nomothetic view of traits suggests that traits are universal and it is possible to compare traits among individuals. It also states that individuals reflect a unique combination of traits, implying that while everyone has the same basic traits, not all individuals have the same levels of each trait. An Ideographic view of traits suggests that traits are idiosyncratic, or not universal. This approach explains that comparisons are not possible among individuals because not all traits are shared.
