The one your workplace paid for
MBTI is a trademark. Using it properly means licensing it, per seat, from a company that certifies practitioners — and at the end it hands you four letters and no working.
A type is only as firm as its weakest letter
Four axes — ownership, control, horizon, method. Twenty-four statements. The first two letters are an ordinary political compass quadrant; the second two cut each quadrant into four. That's the whole trick behind every sixteen-type system: two more axes, nothing mystical.
Then comes the part nobody else reports.
Three cuts cleared comfortably. The fourth by four points out of a hundred. Change one answer and this person is a different type holding identical opinions — and no other test would have mentioned it.
| Score | Band | What it means |
|---|---|---|
| 0–9 | Coin toss | One answer from being a different type. |
| 10–29 | A lean | A tendency, not a conviction. |
| 30–59 | Settled | Comfortably inside the box. |
| 60–100 | Emphatic | Deep in it. The box fits. |
Which is how you end up saying something no other typology lets you say: "I'm a coin-toss anarchist."
Take it with people who'll argue
One map, everyone on it
Send a link. Family, colleagues, the group chat. Everyone lands on the same 2×2 with their scores. Nobody wins — that's the point of it.
Pick who reads it to you
Fifteen hosts, from The Professor to The Sixteen-Year-Old to an anarchist who declares his bias before he starts. One of them is narrated aloud.
It keeps your place
Stop halfway and come back. Past results are kept so you can watch yourself move — because you will, and that's more interesting than any single reading.
Free, and it stays free
The whole instrument is published: the four axes, all twenty-four statements with their exact weights, the scoring procedure, the sixteen type definitions. Licensed CC BY-SA 4.0 — fork it, translate it, run it commercially, build a better front end than this one. The single condition is share-alike, so it can't be closed again.
It would be a strange thing to argue that the left/right line flattens political reality, and then charge admission to the alternative.
For organisations
Three ways this gets paid for
The instrument is free to everyone, permanently. What's for sale is the work around it.
- A commissioned instrument. Your axes, your statement bank, built and calibrated to the same standard and published under the same open licence. For unions, newsrooms, think tanks and campaigns who need to measure something specific and want to own the argument, not rent it.
- White-label embeds. Cutline inside your masthead, your colours, your branding — plus an aggregate portrait of how your own readership actually splits. Counts only; never individuals.
- The hosted API. Scoring as a service if you'd rather not implement the spec. Free tier, paid above it.
So — how nearly are you someone else?
Twenty-four statements. Four minutes. No account, no email, nothing stored about you unless you ask for it.
