Personality and Happiness
Through factor analysis, personality has been narrowed down to the theory called the Big Five Factor, which are these five aspects of heritable personality traits: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Research has shown that personality is 50% heritable. There are two aspects of personality which are related to happiness. There is a strong relationship between Extraversion and happiness, in that the more extraverted a person is (or behaves in fact) the more happy he/she will be. The other aspect of personality which has a strong relationship to happiness is the genetic predisposition to Neuroticism. The more neurotic (emotionally unstable) a person is, the more likely he/she is to be unhappy.[5]
