About this test

This is an estimate of how you performed on a set of reasoning tasks, compared with other people who have taken this test online. It is for education and self-insight only — it is not a clinical, diagnostic, or psychological assessment.

Your score is shown as a range rather than a single number, because every short test carries a margin of error. The same person can score differently on different days.

Many things move the score that have nothing to do with ability: practice, motivation, tiredness, anxiety, distractions, and how used to this style of question you are.

Our comparison group is people who chose to take an online test, which is not a perfect cross-section of the whole population. So read the score as "relative to our test-takers", not as a standardized clinical IQ such as the WAIS.

This test does not diagnose or screen for any condition, does not predict job, school, or life success, and does not measure a fixed or innate intelligence. For a clinical assessment, please see a licensed psychologist.

As more people take the test, the scoring is recalibrated and becomes more accurate over time.
