Your personality predicts how happy you are with your life. A giant review covering 334,567 people found that three traits matter most: how easily you get upset, how outgoing you are, and how organized you are.
Decades of research, 462 groups of people in all, went into the review by Jeromy Anglim's team at Deakin University in Australia. Psychological Bulletin published it in 2020. It used the Big Five, the most common way psychologists measure personality, plus a newer six-trait version that adds honesty and humility.
Getting anxious, sad, or irritated easily, a trait psychologists call neuroticism, was the biggest drag on happiness. The biggest boosts came from being social and energetic, and from being organized and reliable. In the six-trait version, being outgoing was the strongest predictor of all. Smaller pieces inside each trait, like cheerfulness inside being outgoing, predicted well-being about 20 percent better than the broad traits did.
People rated both their own personality and their own happiness, so some overlap comes from how people see themselves. Personality can also shift: a 2017 review in the same journal found that traits, especially emotional stability, changed in measurable ways after things like therapy. The traits most tied to a happy life are also traits people can work on.
