Myers-Briggs type indicator
The Myers-Briggs type indicator is a way to determine what personality type you are.
On The Myers & Briggs Foundation´s official site, they state: "The purpose of the Myers-Briggs Type Indicator® (MBTI®) personality inventory is to make the theory of psychological types described by C. G. Jung understandable and useful in people's lives. The essence of the theory is that much seemingly random variation in the behavior is actually quite orderly and consistent, being due to basic differences in the ways individuals prefer to use their perception and judgment."
