What Is the Happiest Personality? (It Actually Might Be Yours)

AI Summary
5 min readWhat Is the Happiest Personality? (It Actually Might Be Yours)
Arthur Brooks opens with a confession: when a journalist friend asked him to take a personality test, Brooks scored in the 96th percentile for extraversion — meaning only 4% of the population is more extroverted than he is. His friend, who scored at the 15th percentile, responded with two words: "Lucky you." Extroverts, the friend assumed, are simply happier people.
Brooks confirms that the research backs this up — but only partly. Decades of studies show that extroverts have a statistically significant happiness edge over introverts, though the gap is modest, not enormous. Extroverts experience more intense periods of well-being and their general mood is punctuated by frequent moments of joy. But the real question Brooks wants to answer is not whether extroverts are happier — it's what both introverts and extroverts can learn from each other to become happier still.

Show Notes
If you’re an introvert, you might not like what the research has to say: Extroverts tend to be happier. But before you start striking up conversations with strangers in the elevator, there’s more to the story.
In this episode of Office Hours, I explore how your personality might shape your happiness, what introverts and extroverts can learn from each other, and why understanding your natural tendencies can help you cultivate habits towards a more connected and, therefore, happier life.
