Summary
The Trait Theory of Personality posits that personalities are composed of intrinsic traits that are stable over time. One of the most well-known trait theories is the five factor model of personality. This model proposes five traits that make up personality. The first, openness, is characterized by open-mindedness and willingness to try new things. The second, conscientiousness, is characterized by being organized and hard-working. The third, extraversion, is characterized by being outgoing and affectionate. The fourth, agreeableness, is characterized by kindness, and a desire to please others. The fifth, neuroticism, characterized by being nervous, worried, and emotionally unstable.

Example
All of the approaches to Trait theory, including the Five Factor theory, agree that personalities are composed of intrinsic, stable traits, and that personalities do not change over time. For example, if someone has a certain set of traits (stubbornness, extrovertedness) at the age of twenty-five, trait theory would expect them to have the same traits at the age of eighty-five.
