What the Sixteen Types test measures

This free 16 personality types test reads four preferences, each as a pair of opposites, and combines them into a four-letter type. The idea descends from Carl Jung's writing on psychological types; the questions, scoring and type names here are our own.

  • Energy — Extraversion (E) or Introversion (I): whether people and activity recharge you or draw on your reserves.
  • Mind — Intuitive (N) or Observant (S): whether you lean toward patterns and possibilities or toward concrete facts and experience.
  • Nature — Thinking (T) or Feeling (F): whether decisions start from logic and consistency or from values and their effect on people.
  • Tactics — Judging (J) or Prospecting (P): whether you prefer a settled plan or keeping options open.

How the test works

There are 100 statements, 25 for each pair, and it takes about 12 minutes. Some statements describe one side of a pair and some the other, so agreeing with everything does not push you in one direction. You answer each on a five-point scale from strongly disagree to strongly agree.

No account is needed. Your answers are scored in your browser and are not sent to us; when you finish, only your four-letter code is kept, in a cookie on your device, for 30 days.

What your result shows

Your free result gives your four-letter type with its name, a short description, and a percentage for each pair showing how far your answers leaned toward the side you landed on. A 52% lean and a 90% lean produce the same letter, and the percentage is there so you can see which one you are.

An optional full profile, part of a paid purchase, reads your type in more depth: strengths, growth areas, relationships and work style.

The honest limits of a type test

Most people are not clearly one thing or the other on these pairs; they sit somewhere in the middle. A type test still has to hand each person one letter, so two people with nearly identical answers can get different types, and the same person can get a different type on a retake if they sit close to the line. Personality research generally favours measuring traits as continuous scores for this reason.

Use your type as a vocabulary for talking about preferences, not as a verdict. It is not suitable for hiring or other decisions about a person. If you want continuous scores, our main personality test measures six axes and 24 dimensions without forcing a side.

Questions about the Sixteen Types test

Is this an official, licensed type indicator?

No. This is an independent test that uses the same four-letter framework. Its questions, scoring and type names are written by PersonalityLoom, and it is not affiliated with or endorsed by the publishers of any commercial type indicator.

Is the 16 personality types test free?

Yes. The test, your four-letter type, its description and your four percentages are free with no sign-up. Only the longer written profile is paid.

Why did I get a different type from another test?

Different tests use different questions and draw the line between letters in different places. If any of your percentages is close to 50%, a small difference in wording can flip that letter. Look at the percentages rather than the letters alone.

How accurate is a 16-type test?

It describes the preferences you report, and it is most informative where your percentages are strong. It is less dependable near the middle of a pair, where one letter has to be chosen for answers that are close to even. It has not been validated as a basis for decisions about people.
