Big Five Personality Test (OCEAN)

The Big Five Personality Trait Model (often called OCEAN) is the most scientifically robust and widely accepted psychological model of human personality.

Why is Big Five better than MBTI?

The Myers-Briggs Type Indicator (MBTI) forces people into binary categories (e.g., you are either an Introvert or an Extrovert). Human psychology does not work this way; traits exist on a bell curve. Research shows that over 50% of people who take the MBTI get a different result if they retake it just five weeks later.

The Big Five, however, uses standard deviation and percentiles to measure exactly where you fall on the spectrum. This is why it is the gold standard used by university psychology departments and researchers worldwide.
