What kind of person are you?
That's the question that a personality test called the Big Five seeks to answer. You respond to a series of statements about yourself – everything from "I have a kind word for everyone" to "I get chores done right away" – by agreeing, disagreeing or being neutral. Your final score gauges you on a quintet of characteristics: Openness, Conscientiousness, Agreeableness, Extroversion and Neuroticism (or Emotional Stability, depending on which version of the test you take).
Why these five traits?
