Trait theory suggests that there are both traits and types within people that create the personality. Types are categories that have measurable differences. Traits are stable qualities in people that have measurable differences. Examples of traits are things like fairness, intelligence, confidence, and helpfulness. Individual differences are shown 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 (shared) view of traits suggests that traits apply to everyone and it is possible to compare traits among individuals. It also states that individuals show a unique combination of traits. This means that while everyone has the same basic traits, not all individuals have the same levels of each trait. An Ideographic (individual) view of traits suggests that traits are unique to people. This view explains that comparisons are not possible among individuals because not all traits are shared. It says that traits may be different in importance for different groups of people.
