What is the
Myers–Briggs
Type Indicator?

The Myers–Briggs Type Indicator (MBTI) is a self-report questionnaire that makes pseudoscientific claims to categorize individuals into 16 distinct "personality types" based on psychology. The test assigns a binary letter value to each of four dichotomous categories: introversion or extraversion, sensing or intuition, thinking or feeling, and judging or perceiving. This produces a four-letter test result such as "INTJ" or "ESFP", representing one of 16 possible types.
