Myers-Briggs Type Indicator

A chart with descriptions of each Myers–Briggs psychological type and the four dichotomies central to the Jungian theory

The Myers–Briggs Type Indicator (MBTI) is a self-report questionnaire that makes pseudoscientific claims to categorize individuals into 16 distinct psychological types (often called personality types). 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 the 16 types.
