What you’ll get
Answer 70 either/or questions and you get a four-letter type such as INTJ or ESFP, one of 16 combinations, along with the raw tally for each of the four dimensions so you can see whether a preference was decisive or a coin flip. Most people finish in 15 to 20 minutes. Your answers never leave your browser; scoring happens locally and nothing is stored on our servers.
The four dichotomies
Each letter comes from one either/or scale:
- Extraversion (E) / Introversion (I): whether being around people charges your battery or drains it. Not the same as shyness — plenty of confident public speakers are introverts who need the evening alone afterward.
- Sensing (S) / Intuition (N): whether you trust concrete details you can verify or patterns and possibilities you infer. An S reads the manual; an N skims it and starts pressing buttons.
- Thinking (T) / Feeling (F): whether you settle decisions by impersonal logic or by how they land on the people involved. Both are ways of reasoning, not a smart/emotional split.
- Judging (J) / Perceiving (P): whether you want things decided or want options open. A J books the trip two months out; a P finds a hostel at 11pm and calls it flexibility.
How the scoring works
Every question pits one side of a single dichotomy against the other. Choosing option A adds a point to one pole, option B to the opposite pole, and your type is whichever pole wins each of the four tallies. That also means a 9-to-8 split and a 17-to-0 sweep print the same letter. Check your tallies on the results page: a near-even dimension is better read as “no strong preference” than as a fixed trait, and it’s the letter most likely to flip if you retake the test in a different mood.
How seriously to take your result
The framework goes back to Carl Jung’s 1921 book Psychological Types, turned into a questionnaire by Katharine Cook Briggs and Isabel Briggs Myers in the 1940s. Neither woman was an academic psychologist, and the instrument has never been widely accepted in personality research. The standard criticisms, laid out in David Pittenger’s reviews in the 1990s and 2000s: type assignments are unstable (in test-retest studies, as many as half of participants get at least one different letter when retested after about five weeks), and the either/or format forces continuous traits into boxes. Most personality researchers work with the Big Five instead, which keeps traits on a spectrum.
None of that makes the result useless. The four dimensions map onto real, measurable differences between people, and a shared vocabulary for “you recharge alone, I recharge at parties” genuinely helps teams and couples talk about friction without assigning blame. Treat your type as a conversation starter with evidence behind its ingredients, not a verdict with evidence behind its boxes.
Common questions
Is this the official MBTI? No. The official instrument is published by The Myers-Briggs Company and administered through certified practitioners. This is an independent 70-item questionnaire we wrote ourselves, built on the same four-dichotomy framework. It’s free, and for the reliability reasons above, no version of this framework — ours or the official one — should be used for hiring or clinical decisions.
Can my type change? The letters near the middle of your tallies can and do flip between sittings. Large shifts (an INTJ retesting as ESFP) are rare. If your result keeps alternating between two types, read both profiles; the one that stings a little more is usually the better mirror.
What if the description doesn’t fit? Look at your per-dimension tallies first. If one dimension was close, read the type one letter away. If several were close, the Big Five test on this site will give you a more honest picture, because it reports positions on a spectrum instead of forcing a side.
