This personality type test was independently developed according to Jung’s classification system as developed by Myers, Briggs, von Franz, and van der Hoop. It is not the official MBTI test (the Myers-Briggs Type Indicator® MBTI) or any other similar assessment tool, so please do not confuse them. This free test was developed by this site and has shown a high degree of accuracy in distinguishing among the 16 personality types and calculating scores for each dimension. For each question, choose the answer that best reflects how you habitually act. Press the start button to begin.
