What is 16Personalities?
16Personalities is a free online personality test that gives you a five-letter code such as INTJ-A. The first four letters follow the Myers-Briggs format, but its own theory page says it does not use Jungian concepts and instead reworks the Big Five traits into five scales: Energy, Mind, Nature, Tactics, and Identity (Assertive or Turbulent).
You respond to a series of agree-or-disagree statements. 16Personalities scores you on five scales, shows a percentage for each, and combines them into a five-letter type with a written description.

16Personalities limitations
- −Sorts you into types, so someone near the middle of a scale can land on a different letter on a retake
- −Measures personality only: no values, moral foundations, or thinking-style measurement
- −Type labels can feel reductive, since two people with the same code can differ a lot
- −Shares its letters with the MBTI while being a separate model, which can blur what you actually took
