IQ 192

Profoundly Gifted

Last reviewed: September 2026

Quick answer

Yes, and it is extremely rare. An IQ of 192 is higher than all but about 1 in 2.3 billion people.

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.

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

37 of the historical profiles on this site carry an estimate of 160 or more, and none reaches 192. 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:

WherePopulationIQ 192 or higher
UKabout 68 millionfewer than one (0.03 expected)
USabout 335 millionfewer than one (0.14 expected)
Worldabout 8.1 billionabout 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.

Is 192 a good IQ?

Yes, in the sense that it is extraordinarily high: about 1 in 2.3 billion on the bell curve, 32 points past the ceiling of most major tests. The catch is precision. A single 192 is better treated as "well above 150" than as an exact score.

What percentile is an IQ of 192?

An IQ of 192 is at about the 99.999999956th percentile. That means it is higher than 99.999999956% of people, while 0.000000043% score the same or higher, about 1 in 2.3 billion. The figure assumes the standard scale, with a mean of 100 and a standard deviation of 15.

Is 192 genius level?

By most informal definitions, yes. There is no clinical genius category, but scores above 140 or 145 are often labelled that way, and 192 is well past both. Historically, though, genius is defined by achievement, and no test measures this high precisely.

What does an IQ of 192 mean?

It means you scored 6.13 standard deviations above average on the kind of reasoning an IQ test samples, which this site classes as Profoundly Gifted. Most tests cannot measure this high precisely. It measures reasoning on that test, not knowledge, creativity or character.

How rare is an IQ of 192?

192 or higher happens in about 1 in 2.3 billion people. In the UK that is fewer than one person. Scoring exactly 192, meaning 191.5 to 192.5 on a continuous scale, is about 1 in 5.5 billion. Both figures come from the standard bell curve, not a census.

What is the mental age for an IQ of 192?

Mental age is a childhood measure. On the old ratio scale, a 12-year-old with an IQ of 192 performed like a typical 23-year-old. For adults the idea breaks down, because reasoning scores stop rising with age, so modern tests compare you with people of your own age.
