Your mind tracker

The item types come from psychometrics, the field that measures reasoning. The same families sit in published research batteries, which is why they can be built to rules instead of invented.

We use no material from Raven’s Matrices or any other protected test. Every item is generated from named rules, following published work on item generation.

• What completes a grid
• What continues a series
• What does not belong
• What stays the same when a shape is stretched
• What an object looks like turned around
• What number comes next

Six subtests, 36 scored items in six blocks, one practice item before every block, and a timer on each block

Nothing to remember and nothing to look up: it is not knowledge, vocabulary, schooling or memory

• Exactly one answer is correct: a solver proves it for every item before the item enters the bank
• Wrong options are named mistakes, not random shapes
• Six options in every block, so a guess is worth the same everywhere
• No vocabulary: “?” is the only character you will see in an item
• No colour: items are ink on paper, so colour vision does not change your score
• Three forms, matched position by position, so a retest compares with your first run
• Difficulty is a tier and a count of rules, not an opinion

Each line above is a test in our build. A bank that fails one of them does not ship.

There is no unit of intelligence, so a score is a position, not an amount. 100 is the middle of the group you are compared with, and that group is named on your result.

• A range, not a single number. The range is the measurement; a bare number is a claim
• A percentile among people who finished the same test, and the group you are compared with is always named on screen
• Norms carry a version, and so does the item bank; your result records both

• This is not a clinical or diagnostic assessment
• Our test has not been validated against WAIS, Stanford–Binet or any other clinical instrument
• Research findings about intelligence describe groups, never the person reading them
• We do not tell you what your score predicts about your income or your work
• One sitting gives one overall score, not a map of your strong and weak sides; that needs more items than a single session holds

Open, published work on matrix item generation and on short public intelligence batteries: ICAR and the Sandia matrix generator

Yes. The score and its range are shown right away and stay free. No card, no signup. A detailed report will be a paid add-on later; the first participants get it free.

No, the email is optional: it saves the result in your cabinet and delivers the report. We do not spam: we write only about your run, result and report, send no advertising and share the address with no one.

36 items in six blocks, usually 15 to 20 minutes: everyone has their own pace. You can stop halfway and still get a result, but we advise finishing: a short result is compared only with other short ones, there are few of those yet, and its range is noticeably wider.

One session measures a day, not a person: sleep, device and attention all move the score. 36 items give a range, and we show it because a number separated from its range starts living as a claim about a person.

Each item has one correct answer, checked on the server. The score is the number of correct answers with a confidence interval; the percentile appears once at least 100 completed runs of the same length have been collected, and it is shown together with the size of that base.

Yes. A second scored run opens 90 days after the first; earlier runs are recorded but not scored, so that practice does not pass for ability. Norms use each person's first run only.

Practice improves the score on this test, not the ability it measures: in large reviews the gain from training does not transfer to other tasks. So the goal of the test is not a rising number but an honest snapshot of your ability now and, with repeats, your own trajectory: comparing you with yourself, not chasing a figure. Repeat runs are spaced out and use a different form of the items, and we call a change a change only when it exceeds the measurement error. We do not promise growth: if the score went up over six months, the honest caption is "you learned the format", not "you got smarter".

Answers, times and the year of birth are stored for scoring and for the norms; there is no advertising, no session recording and no selling of data. You can export or delete everything in your cabinet at any time.

No. It is a self-assessment tool, not a clinical instrument, and its result is not a diagnosis of anything. The methodology is published on this site, including its limits.
