Is an IQ of 152 good?
By the numbers, an IQ of 152 is exceptional — the kind of score only a tiny fraction of people reach. But "genius" is a loose popular term, not a scientific category, and at these extremes a short online test is least precise. Treat 152 as a sign of very strong reasoning, not a verdict on a person; achievement at this level still depends on what someone actually does.
How rare is an IQ of 152?
An IQ of 152 is extremely rare — about 1 in 3800. Fewer than under 0.1% of people reach it; in a random group of 1,000 you would expect at most about 1. Scores this far out also carry the widest measurement error.
What an IQ of 152 looks like in practice
At this extreme, score differences become hard to measure reliably and tell you little about any individual. Reasoning power is abundant; what shapes outcomes is how it's applied.
IQ 152 compared to nearby scores
No short test pins ability to a single point. An IQ of 152 is best read as the centre of a range — roughly 148 to 156 — rather than an exact value, and it is not meaningfully different from scores a few points either side. When you compare two people, overlapping ranges matter more than the point scores.
