The Myers-Briggs Type Indicator (MBTI) is a personality assessment tool designed to categorize individuals into 16 distinct personality types. It is based on the psychological theories of Carl Jung and focuses on four dichotomies: Introversion vs. Extraversion, Sensing vs. Intuition, Thinking vs. Feeling, and Judging vs. Perceiving. Each person is identified by a four-letter code representing their preferences in these areas. The MBTI is widely used in various settings, including personal development, career counseling, and team building. It helps individuals understand their own behaviors and preferences, as well as those of others, promoting better communication and collaboration. While the MBTI is popular, it is important to note that it has its critics and should be used as one of many tools for self-discovery.
