The Big Five Personality Model — What Does It Say About You?

What Is the Big Five Model?

The Big Five model (also known as OCEAN or the five-factor model) is currently the most extensively validated scientific model of personality. It emerged from analyzing thousands of word descriptions of personality across different cultures and languages.

Unlike popular but scientifically unvalidated tests (MBTI, enneagram), the Big Five has been replicated in dozens of countries and cultures.
