The Myers-Briggs Type Indicator (MBTI) is a personality assessment based on Carl Jung’s theory of psychological types. It measures individuals’ preferred manner of interacting with the world using four dichotomous scales, making up 16 possible personality types. The personality types are represented by four letters that indicate an individual’s preference on each of the scales. The four scales are:

• Extraversion-introversion
• Sensing-intuition
• Thinking-feeling
• Judging-perceiving
