— IQ score explained
IQ of 82 — meaning, percentile & profile
An IQ of 82 is in the low-average range, below 88% of adults. This does not predict life outcomes — context, motivation, and skills matter enormously.
What does IQ 82 mean in practice?
An IQ of 82 means your raw performance on a standardised IQ test places you at the 12th percentile of the general adult population — lower than 88% of people. Many people at this level succeed across a wide variety of careers and life domains with the right conditions and strategies.
IQ 82 and the normal distribution
IQ is defined with a mean of 100 and a standard deviation of 15. An IQ of 82 is 1.2 standard deviations below the mean. The normal distribution tells us that:
- 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
- An IQ of 82 is higher than 12% of the adult population
IQ 82 and career outcomes
Career success depends on far more than IQ — motivation, perseverance, social skills, practical reasoning, and domain knowledge are all equally or more important than the IQ number for most real-world outcomes. Many people with IQs in this range lead highly successful and fulfilling careers.

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.
