An IQ of 152 places you in the top 0% of the adult population — a profoundly rare score that only about 1 in 1000 people reach.

What does IQ 152 mean in practice?

An IQ of 152 means your raw performance on a standardised IQ test places you at the 100th percentile of the general adult population — higher than 100% of people. People at this level typically find abstract reasoning, pattern-matching, and learning new skills comes naturally.

• About 68% of people score between 85 and 115
• About 95% of people score between 70 and 130
• About 99.7% of people score between 55 and 145

How to accurately measure your IQ

A reliable IQ test uses Item Response Theory (IRT) scoring, which adapts the scoring based on item difficulty parameters rather than simply counting correct answers. Core Brain uses IRT 3PL (three-parameter logistic) scoring — the same statistical framework used by the WAIS and Stanford-Binet — and returns your score with a 95% confidence interval so you know the measurement uncertainty.
