The Myers-Briggs Type Indicator (MBTI) is one of the world's most widely used personality tests. First published in 1962, the questionnaire was developed by amateur psychologists Isabell Myers and her mother Katherine C Briggs, based on their work with Swiss psychiatrist Carl Gustav Jung's theory of personality types.
The MTBI is a forced-choice test built around the following four opposing personality scales, or dichotomies:
- Extraversion or Introversion
- Sensing or Intuition
- Thinking or Feeling
- Judging or Perceiving
Based on these preferences, the test taker will be categorized as one of 16 possible personality types designated with a four-letter code, with each letter signifying one of the personality dichotomies.
