IQ Test Methodology

MyIQScores provides an online IQ-style reasoning estimate for educational use. The test is designed to help visitors practice common cognitive question formats and understand how score ranges work, not to replace a professionally administered assessment.

What the Test Measures

The assessment includes 30 questions across five broad cognitive domains. Each domain mirrors a skill commonly represented in standardized cognitive testing, while staying suitable for a short online format.

• Pattern recognition: identifying visual, numerical, or symbolic rules.
• Logical reasoning: applying rules and eliminating inconsistent answers.
• Spatial reasoning: mentally rotating, comparing, or completing shapes.
• Numerical reasoning: recognizing quantitative relationships and sequences.
• Working memory: holding and manipulating information during a problem.

How Results Are Estimated

Results are based on answer accuracy, question difficulty, and completion time. The final score is mapped to familiar IQ score ranges so visitors can understand whether a result is around average, above average, gifted, or unusually high.

Because this is a web-based estimate, the result should be interpreted as a learning aid. Test environment, fatigue, device size, prior exposure to similar questions, language background, and distractions can all affect performance.

What This Test Is Not

MyIQScores is not a clinical instrument and has not been normed in the same way as the WAIS, WISC, Stanford-Binet, or Raven's Progressive Matrices. It should not be used for medical diagnosis, school placement, hiring, disability evaluation, or any decision requiring a licensed professional.

Professional IQ Testing

A formal IQ score should come from a licensed psychologist or qualified examiner using a validated test battery under controlled conditions. If you need an official result, start with our guide to types of IQ tests and then contact a local licensed clinician or school psychologist.

How We Compile Celebrity and Public Figure IQ Estimates

None of the public figures featured on our famous IQ pages have released verified, professionally administered test results, with very rare exceptions noted on the individual page. Every figure we publish is an estimate, and we present it that way. Each estimate is compiled from publicly available signals: documented academic records and admission test scores where they exist, historiometric studies such as the Cox (1926) analysis of historical geniuses, statements the person or their biographers have made, and the cognitive demands of their documented achievements. Where credible sources disagree, we publish a range rather than a single number, and we widen the range when the underlying evidence is thin.

These estimates are for education and entertainment. They should never be read as measured scores, and a disclaimer to that effect appears on every celebrity page.

How We Build Data Pages

Pages covering average IQ by country, US state, career, and college major draw on published research: international cognitive assessment datasets, NAEP and standardized testing patterns, and occupational studies that report group averages. Group averages describe distributions, not individuals, and sampling methods vary between studies, so we present these figures as estimates with context rather than precise measurements. Percentile and rarity figures on score pages are calculated directly from the normal distribution with a mean of 100 and a standard deviation of 15, which is the convention used by major modern IQ tests.

How We Improve the Test

We review question clarity, completion patterns, user feedback, and result explanations over time. When a question is confusing, ambiguous, or too dependent on cultural knowledge, it can be revised or removed. Content corrections can be sent to content@myiqscores.com.
