Why isn't this a subscription?

Because a cognitive estimate is not something you consume monthly. You pay once, the assessment stays unlocked on your account, and you can retake it whenever you want.

Is this a clinical IQ test?

No. It is a self-knowledge estimate built on research-based item types. It is not diagnostic and not a substitute for a supervised assessment.

Why is a range better than a single number?

A range tells you the truth about precision. Two people with the same single score can have meaningfully different underlying ability; the interval makes that uncertainty visible instead of hiding it.

Do I need an account?

Yes for the paid assessment, because the unlock and your saved attempts have to live somewhere. The free short test needs no account at all.

People who are curious about how they think, want a benchmark that is honest about its limits, and would rather read an explanation than a one-word verdict.

The full adaptive form produces a substantially tighter interval than the short form. Your report states the interval explicitly rather than asking you to trust a number.

What happens after purchase?

Access is granted immediately after payment. You are returned to the site, the full assessment unlocks on your account, and a receipt appears in your account page.

What changes

What you actually gain

The upgrade is about precision and understanding, not about answering more questions for their own sake.

A more precise estimate

48 adaptive questions cut the margin of error from about ± 7 points to about ± 4. In plain terms: a range you can actually reason about instead of a wide guess.

A fuller picture of how you think

Six kinds of thinking, scored separately, so you can see where your reasoning is strongest and where it costs you more effort.

An explanation, not a verdict

Your report walks through the questions that moved your estimate and why, so the number stops being a black box.

Something you can keep

Saved attempts, a comparison over time and a certificate you can share — all tied to your account.

Compare

Free short test vs full assessment

Both use the same research-based item types and the same scoring model. The difference is how much uncertainty is left at the end.

Example report extract

How your range was built

You answered 48 items. Difficulty rose after your fourth correct matrix item and settled near the top of the bank, which is why the interval narrowed from ±11 to ±7 points.
