About this test
This is not a substitute for a standardised IQ test, and it should not be read as one. A WAIS or a Raven matrices test is administered by a psychologist, over tens of minutes, under controlled conditions, and above all it is normed: the raw score is compared against a representative sample of the same age, built for the purpose. None of that applies here. The figures shown are rough landmarks, calibrated on Quelmoi participants — a self-selected crowd, not the general population.
Three further reasons to hold the number loosely. Conditions: you may be tired, interrupted, or free to reload the page. Length: twenty questions is far too few for a stable measurement, and a single miss moves the result noticeably. Practice effects: anyone who has already taken ten tests like this recognises the item families and gains points without gaining in reasoning — which is also why real tests are not meant to be retaken at will.
What this test does do honestly is show you which families of reasoning trip you up. Arithmetic series, series with two alternating rules, verbal analogies, matrices, spatial orientation, deductive logic. The correction for every question is shown at the end, and that is where the useful information lives — not in the number.
How it works
Twenty questions in rising order of difficulty, one correct answer each, no timer. Your score is the percentage of correct answers; the result band attaches an indicative order of magnitude, not a measurement.
