WHAT IT MEASURES

Your preferences on four pairs (Introversion/Extraversion, Sensing/Intuition, Thinking/Feeling, Judging/Perceiving), combined into a probability spread across the 16 types instead of one forced label.

THE SCIENCE

The 16-type framework grew out of Carl Jung's theory of psychological types and was developed into a questionnaire by Katharine Briggs and Isabel Briggs Myers. Research suggests its four dimensions overlap with Big Five traits, and type categories are less stable than continuous trait scores, so treat the result as a useful vocabulary for preferences, not a fixed identity. This is an independent MBTI-style estimate. It is not the official MBTI instrument and is not affiliated with or endorsed by The Myers-Briggs Company.
