What this test scores
Most four-letter quizzes ask you to collect E or I, N or S, T or F, J or P, and then guess a function stack afterwards. This one does the reverse. The items are written from Jung’s eight function-attitudes — thinking, feeling, sensation, and intuition, each turned toward the outer object or toward the inner impression a thing leaves — and the type is fitted to those scores after the fact.
Extraversion here is not sociability. It is whether the function is oriented by the shared world or by the subjective factor. That is why a test that only asks whether you like parties cannot tell Ni from Ne, or Fi from Fe.
How the fifty-two work
Each function-attitude has six statements, including one reverse-keyed item so that agreeing with everything does not raise every bar. You tap how true a sentence is, from 1 to 5, and a tap moves you on. Most people finish in about eight minutes.
The first stretch looks for the leading function. If two attitudes still land together — Fi and Ti both high, or Ni and Ne — a short follow-up at the end asks which sentence is more you, not another set of ratings. Those answers are folded into the percentages, the winner’s bar rises, and that is what names the lead.
What you see at the end
The free result is eight 0–100% bars and a suggested type whose Beebe stack fits those bars, with the Hero / Heroine weighted first. A type whose leading function is not your strongest score is set aside. If the suggestion feels like a coat you borrowed, you can try a different lead and support on the results page.
Your Type in Depth is a longer reading of the weaker end of the stack: Eternal Child, Inferior (Anima / Animus), the eight roles, growth, and shadow. It is optional. The quiz, the scores, and the choice of Hero / Heroine and Parent stay free.
Not the official MBTI® instrument
The Myers-Briggs Type Indicator is a separate, trademarked test with its own items and publisher. This site is not affiliated with it. A Jungian cognitive functions test, if it is honest, starts with the eight attitudes Jung described in Psychological Types (1921), and only afterwards asks which classical stack those scores resemble.
The four-letter code is a later shorthand, useful for talking about a stack, and a poor way of measuring one. If you arrived here looking for “the MBTI test,” you can still take this; just know what it is scoring.
Answers stay in this browser
There is no account and no database of answers. The ratings stay on this computer until you start over. After a finished quiz, the site may record which type was suggested and which stack you left on the results page, as counts only, so the test can be checked against published population shares.
