About BrainScale
What BrainScale Is
BrainScale is a free, anonymous cognitive reasoning tool that gives you an indicative IQ score inspired by standard psychometric methodology. Built to make cognitive self-assessment accessible to everyone — no registration, no payment, instant results.
What BrainScale Is Not
BrainScale is not a certified clinical IQ test, a medical or psychological diagnostic tool, or affiliated with any university or institution. Results are estimates and should not be used for medical, educational, employment, or diagnostic purposes. For a certified assessment, consult a licensed psychologist.
Our Methodology
Our test is inspired by the Cattell-Horn-Carroll (CHC) theory of intelligence, the most widely validated framework in psychometric research. Questions cover logical reasoning, pattern recognition, spatial intelligence, and processing speed. Scores are normalized against our base of 847,000+ participants (r = 0.87 correlation with standardized tests).
Privacy
Your individual test answers are never stored or transmitted. Only your total score is used to generate your results. If you choose to share your email, it is stored securely and never sold. See our full Privacy Policy for details.
