Intelligence Distribution
IQ scores follow a normal distribution across the global population, with a mean of 100 and a standard deviation of 15. The chart below shows how scores distribute across 1,000 people.

The Science
Three centuries of research have refined how we measure human cognition. Here's what the science actually says.
The Intelligence Quotient (IQ) is a standardised measure of cognitive ability, first developed by Alfred Binet in 1905 to identify students needing educational support. David Wechsler later refined it into the deviation IQ — scoring relative to a normative population with a mean of 100 and SD of 15. Today's assessments draw on 120 years of psychometric refinement.
Modern IQ tests assess multiple cognitive domains including working memory, processing speed, verbal comprehension, and perceptual reasoning. Scores are computed relative to a large normed population, ensuring that a score of 100 always represents exactly average performance for your age group. Our assessment uses standardised question formats aligned with Wechsler and Raven's Progressive Matrices traditions.
Longitudinal research spanning 50+ years demonstrates that cognitive assessment scores are among the strongest predictors of academic achievement, occupational success, and long-term health outcomes. Understanding your cognitive profile can inform career decisions, educational strategies, and help identify areas for targeted cognitive development. Knowledge is the first step to growth.
Assessment Format
Our assessment covers the three core domains of cognitive ability used in validated psychometric testing.
Visual-spatial reasoning and matrix completion tasks. Identify hidden rules in sequences of shapes, numbers, and abstract figures — the purest measure of fluid intelligence.
8 QuestionsAnalogies, vocabulary, and linguistic pattern questions. Measures crystallised intelligence and the ability to understand and manipulate language and abstract relationships.
9 QuestionsMathematical patterns, arithmetic progressions, and numerical reasoning. Assesses quantitative reasoning and the ability to identify rules governing numerical relationships.
