What does QI1 measure?

QI1 is a short reasoning challenge designed to observe how you solve different kinds of problems under a common time limit. The twenty questions are distributed across four areas: logic, pattern recognition, numerical reasoning and verbal reasoning.

Each question has the same scoring structure for every participant. The translated versions preserve the same underlying problems and answer keys so that changing language does not create a different test.

Four reasoning areas

LogicDeduction, relationships and necessary consequences.

PatternsSequences, regularities and structural recognition.

NumericalQuantitative relationships and short problem solving.

VerbalRelationships between concepts, words and meanings.

How should I read my result?

After the test, QI1 creates an indicative overall index and a breakdown across the four areas. The score is intended for recreational comparison and personal curiosity. It is not a standardized IQ score and should not be used for clinical, educational, employment or diagnostic decisions.
