Big Five
The five-factor model — the most empirically grounded personality framework
About Big Five
The Big Five (also called OCEAN) is the personality framework with the strongest empirical backing in modern psychology. Rather than sorting people into types, it scores each person along five continuous dimensions: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Most people sit somewhere in the middle of each, with characteristic leanings.
The Big Five doesn't replace astrology any more than a thermometer replaces a sunset. It just gives you a more measurable language for the temperament you already know you have. Reading your sun sign through these five dials often makes the picture more specific.
