Four-Letter Type Test — The Dichotomies, Scored as Gradients

The four preference pairs behind every four-letter type, measured without the cut at the middle: you get a letter, and you get how close that letter came to flipping.

You'll find out: Your four letters, plus the margin on each one — so you can tell which part of your type description is a finding and which part is a rounding artifact.

What this is really asking

Four questions, asked six ways each. Where your attention goes when nothing is demanding it and what company costs you. Whether you reach first for what is physically there or for what it might mean. Which consideration wins when the fair call and the kind one point in different directions. And whether a decision closing feels like relief or like losing your options.

Those four are the dichotomies Jung's typology proposed and that every four-letter system since has used. What this version does differently is refuse the final step. A standard type instrument takes your score on each pair, cuts it at the midpoint, and hands you a letter — which works cleanly for the people at the ends and badly for everyone else, because scores on these four pairs pile up in the middle like height rather than splitting into two camps. If you land two items from the line, you get a confident letter that a retake weeks later may well reverse.

So each pair here is reported as a position with a margin attached. You still get the four letters, because that is the vocabulary you came for and it is genuinely useful shorthand. But a letter with a three-point margin is labelled as one, and that label is the most informative thing on the page: it tells you which part of your type description to take seriously and which part is a rounding artifact you have been carrying around as an identity.

This is not the Myers-Briggs Type Indicator® and it does not reproduce any part of it. That instrument is copyrighted and its name is a registered trademark of The Myers-Briggs Company. These items are our own, written on the four-dichotomy framework as it appears in the open literature — the same framework the public-domain Open Extended Jungian Type Scales works from.

The parts it pulls apart

  • Introversion – ExtraversionWhere attention goes by default, and what contact costs you
  • Sensing – IntuitionWhether you reach first for what is there or what it means
  • Thinking – FeelingWhich consideration wins when the fair call and the kind one differ
  • Judging – PerceivingWhether a decision closing is a relief or a loss

What lands on your screen at the end

Four bars, one per pair, each showing where you sat and how far that was from the midpoint. Above them, the four letters that position produces — with any letter inside ten points of the middle marked as borderline, meaning that letter is the one most likely to read differently if you take this again in a month.

Then the part that is specific to this site: which of our other assessments measures the same territory on a continuous scale, and what a behavior task would predict about you if the letters are accurate. Your type says something checkable about how you act when a loss is immediate and the odds are hidden. The balloon task records what you actually did. Those two agree less often than people expect, and where they disagree is more interesting than either one alone.

Where these questions came from

Jungian four-dichotomy framework (via OEJTS)

Jung, C. G. (1921). Psychologische Typen. Rascher Verlag. Framework as operationalised in the Open Extended Jungian Type Scales (2013), released to the public domain.

This version: An original scale of 24 items written on the four-dichotomy framework. It is not the Myers-Briggs Type Indicator®, reproduces none of that instrument's items, and carries none of its norms — the trademarked instrument is copyrighted and separately licensed. Where this version departs from the framework deliberately: scores are reported as gradients with the margin from the midpoint shown, rather than as four letters alone.

Common questions

Is this the official MBTI test?

No. The Myers-Briggs Type Indicator® is a copyrighted instrument and a registered trademark of The Myers-Briggs Company, licensed through certified practitioners. This is an original 24-item scale built on the same underlying four-dichotomy framework from Jung's typology, which is not itself proprietary. It will usually return the same letters, and it reports the margin on each one, which the branded instrument's standard report does not.

Why did I get a different type than last time?

Because your scores on these four pairs are almost certainly not at the extremes, and a four-letter result comes from cutting each pair at its midpoint. Anyone sitting near a midpoint can flip that letter on a handful of items — an ordinary amount of day-to-day variation. Retest studies of four-letter instruments consistently find a large minority of people change at least one letter after a few weeks, concentrated near the cut points. Nothing about you changed; the rounding did. This is exactly why the margin is shown here.

Which is better, the four letters or the Big Five?

They answer different questions. The Big Five is the model academic psychology settled on: five continuous traits, stable on retest, with documented relationships to job performance, relationship outcomes and health behavior. The four-letter type is better vocabulary — it is memorable, it is shareable, and four of the five Big Five traits map onto the four dichotomies reasonably well. The trait it has no equivalent for is neuroticism, which is the single most predictive of the five. Take both: the letters for the shorthand, the Big Five for the prediction.

How long does this take?

About five minutes for the 24 items. There is no account required, nothing is shared, and you get the four letters plus the margin on each one immediately. If you want the fuller picture underneath the letters, the eight cognitive functions assessment on this site scores what the four letters compress, and takes about seven minutes.
