What gets measured
Core dimensions of cognitive ability

This test measures three core dimensions of cognitive ability: abstract reasoning (identifying patterns and relationships in abstract information), numerical reasoning (understanding numbers and mathematical relationships) and verbal reasoning (logic and comprehension). Together, these dimensions capture the essence of general cognitive ability โ€” g factor โ€” in a compressed format.

01

Pattern Recognition

Identify patterns, sequences and visual relationships. Fundamental to all reasoning.

02

Logical Reasoning

Apply logic rules, evaluate deductions and solve systematic problems step by step.

03

Problem-Solving

Approach novel problems systematically and identify efficient solutions.

Common questions
Frequently asked questions
QHow accurate is a 15-question test compared to a full IQ test?
A 15-question test provides a useful snapshot of your core reasoning ability but with less measurement precision than a comprehensive 40+ question assessment. Think of it like taking a person's temperature with a quick forehead scan versus a full medical exam โ€” it tells you something meaningful but with broader confidence intervals. This test is reliable for distinguishing broad ability categories but less precise for identifying small score differences.
QWhy are there fewer questions?
Fewer questions means less measurement precision but also faster completion. This test prioritises speed and accessibility โ€” perfect for quick self-assessment or deciding whether you want to take a full assessment. The 15 questions are strategically selected to capture the core reasoning dimensions that longer tests measure across many more items.
QHow does this compare to online IQ tests I've seen?
Many online "IQ tests" are entertainment-focused quizzes without genuine psychometric foundations. This test is constructed on principles used in research-grade cognitive assessments โ€” selecting items that correlate strongly with general cognitive ability (g factor) and avoiding culture-specific or knowledge-dependent content. It is not a clinical diagnostic tool, but it is based on real cognitive science.
QShould I use this test for clinical decisions?
No. This is a screening and educational assessment only. If you need to determine giftedness, identify learning disabilities or make clinical decisions about cognitive ability, a formal assessment by a qualified psychologist is essential. This test is designed for self-knowledge and curiosity, not clinical diagnosis.
QWhat if I want a more comprehensive assessment?
We offer full-length cognitive tests measuring more domains and providing greater measurement precision. The Adult IQ Test (40 questions) provides a complete cognitive profile. Start with this fast test if you're new to cognitive assessment; graduate to the full test if you want detailed insights into your specific cognitive strengths and weaknesses.
