Most tests cannot measure this high reliably, so read a 192 as "far above 150" rather than an exact number. The rarity comes from the bell curve model.
An IQ of 192 falls in the profoundly gifted IQ range, which starts at 160. Find 192 on the IQ chart, or check how rare any score is with the IQ rarity calculator.
IQ 192: beyond what most tests can measure
Taken literally, the bell curve puts 192 at 1 in 2.3 billion: not even one person in the UK and about 3 people worldwide. Treat that as an illustration of the model rather than a head count.
No test has enough people in its norm sample to check its accuracy at 192. In a 2,200-person sample the bell curve expects effectively nobody at 192 or higher.
Some tests publish extended norms above 160 for exceptional children. These rest on very small samples and on modelling, so they are best treated as rough rankings.
How claims like "192 IQ" arise
A 192 almost never comes from a modern, supervised adult test. It usually comes from somewhere like this:
- Ratio IQ. Early childhood tests divided mental age by real age. A 6-year-old solving puzzles like a typical 11.5-year-old got a ratio IQ of 192. Modern deviation IQs do not work this way.
- Unnormed online quizzes. A test with no norm data can print any number. Very high outputs usually say more about the scoring than the person.
- Repetition without a source. Numbers attached to celebrities are often copied from site to site with no test report behind them.
Famous estimates: Newton, da Vinci and the 160+ club
42 of the historical profiles on this site carry an estimate of 160 or more, and 1 reaches 192 or higher. Isaac Newton and Leonardo da Vinci are the classic examples. Their numbers are retrospective judgements based on their work, not test scores.
As far as anyone knows, Albert Einstein never took an IQ test. The 160 figure repeated online is an estimate. See the Einstein profile for what it rests on.
How many people have an IQ of 192 or higher?
On a bell curve with a mean of 100 and a standard deviation of 15, about 0.000000043% of people score 192 or higher. Applied to whole populations:
| Where | Population | IQ 192+ |
|---|---|---|
| UK | 68 million | fewer than one (0.03 expected) |
| US | 335 million | fewer than one (0.14 expected) |
| World | 8.1 billion | 3 |
You would need the whole world to expect about 3 people at 192 or higher.
The share scoring exactly 192, between 191.5 and 192.5, is about 1 in 5.5 billion. Across the world that would be about 1 person.
The figures are bell curve estimates for whole populations, children included, and rounded. Real tests are normed separately and will differ a little.
How rare is an IQ of 192?
Compare the neighbours: 187 or higher is about 1 in 300 million, 192 or higher is 1 in 2.3 billion, and 197 or higher is 1 in 20 billion. Each point up here adds roughly 52% to the rarity.
What your 192 could really be. At this height the margin of error is wide. Just 5 points either way, 187 or 197, changes the model rarity from 1 in 300 million to 1 in 20 billion, which shows how fragile such numbers are.
Which scale was it on? Most modern tests use a standard deviation of 15, which is what this page assumes. If your 192 came from a test using an SD of 16, it is about 186 on the SD 15 scale. From an SD 24 scale, used by some Cattell-style reports, it is about 158.
Famous people with an estimated IQ near 192
Nobody famous has a verified IQ in most cases, and retrospective estimates are only made for a narrow group.
Our historical estimates start at 115, so nobody sits close to 192. That is not because famous people score higher. Estimates are only attempted for people with extraordinary records, which leaves ordinary scores unrepresented.

Percentiles and counts use a normal distribution with mean 100 and standard deviation 15. Real tests have their own norms, confidence intervals and ceilings, so treat every figure here as an approximation, not a diagnosis. Two tests often give different numbers for the same person: here is why.
