From research to published page

Four stages. Select one to see what happens in it.

Psychometric researchTests are informed by published research on intelligence testing, working memory, pattern recognition, fluid reasoning and processing speed, including the public literature on Raven's Progressive Matrices, the Wechsler scales and the Cattell-Horn-Carroll framework.

CHECKS AT THIS STAGE

The ability being measured is defined first

The method is documented on the methodology page

Contested findings are flagged as contested

The research we draw on

Peer-reviewed journals and the technical literature of the major test publishers. Where findings are contested, such as the nature of general intelligence, the Flynn effect or the limits of brain training, we describe the debate rather than pick a side.

SCOPE OF OUR TESTS

Screening and self-assessment tools

Our tests are designed for curiosity, self-exploration and cognitive practice. We explain the scoring model, item calibration and measurement approach openly on every result, in the methodology and here.

CLINICAL ASSESSMENT IS A DIFFERENT THINGInstruments such as the WAIS-IV, Stanford-Binet 5 and KABC-II are given one-to-one by licensed psychologists under standard conditions, with norms from large representative samples.

WAIS-IVStanford-Binet 5KABC-II

For diagnosis, giftedness identification, school placement, employment selection, clinical, forensic or legal decisions, a licensed psychologist using a clinical instrument is the right route.

Who writes our content

Articles on intelligence, cognition and learning are written by contributors with backgrounds in psychology, cognitive science, neuroscience or educational research. Test items come from contributors with psychometric or psychology experience, and every item is reviewed for content validity (does it measure what it claims?) and difficulty calibration (does its observed difficulty match its design?).

Final editorial responsibility rests with Emir B., who founded What's Your IQ in 2020 and remains its editor.

How we use software and AI

Content is written and edited by people, and human editorial accountability is non-negotiable for claims about human cognition. Software tools support the workflow: search, reference management, grammar checking, translation review and illustrative images.

Translations into our nine languages are reviewed by a human editor before publication.

ADVERTISING & INDEPENDENCE
