IQ 184
Profoundly Gifted
Quick answer
Yes, and it is extremely rare. An IQ of 184 is higher than all but about 1 in 93 million people.
That is 24 points beyond the ceiling most major tests publish, so the number itself is less certain than its rarity suggests.

Where 184 falls on the bell curve
This wider chart runs to 200 so 184 can be shown in place. The curve is so thin out here that the share of people beyond the marker is invisible at this scale.
IQ 184: beyond what most tests can measure
Taken literally, the bell curve puts 184 at 1 in 93 million: about 1 people in the UK and about 87 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 184. In a 2,200-person sample the bell curve expects effectively nobody at 184 or higher.
Real populations may not follow the bell curve perfectly in the far tails, so rarity figures this extreme are illustrations, not head counts.
How claims like "184 IQ" arise
If someone tells you they have a 184, the first question is where the number came from. The usual answers:
- Different scales. Some tests use a standard deviation of 24, so a 184 there is about 153 on the usual SD 15 scale.
- 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 1 reaches 184 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 184 or higher?
On a bell curve with a mean of 100 and a standard deviation of 15, about 0.0000011% of people score 184 or higher. Applied to whole populations:
| Where | Population | IQ 184 or higher |
|---|---|---|
| UK | about 68 million | about 1 |
| US | about 335 million | about 4 |
| World | about 8.1 billion | about 87 |
You would need the whole UK to expect about one person at 184 or higher.
About 1 in 240 million people would score exactly 184, meaning between 183.5 and 184.5 on a continuous scale. In the UK that is fewer than one 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 184?
An IQ of 184 or higher is 6.5 times rarer than 179 or higher, and 189 or higher is 7.2 times rarer again. At this point on the curve, each extra point makes a score about 47% rarer.
What your 184 could really be. At this height the margin of error is wide. Just 5 points either way, 179 or 189, changes the model rarity from 1 in 14 million to 1 in 670 million, which shows how fragile such numbers are.
Which scale was it on? A 184 reported on an SD 16 scale converts to about 179 on the usual SD 15 scale, and one from an SD 24 scale (seen in some Cattell-style results) to about 153. Check which scale your score report used.

Is 184 a good IQ?
It is about as high as the scale goes. The bell curve puts 184 at 1 in 93 million, but major tests are only checked up to around 160, so the exact figure is uncertain. As a description of reasoning ability, "exceptional" fits better than any precise number.
What percentile is an IQ of 184?
On the standard scale, 184 lands at about the 99.9999989th percentile: only 0.0000011% of people match or beat it. Percentiles depend on the scale, so check that your score report uses a standard deviation of 15 before comparing it with this page.
Is 184 genius level?
The genius label is informal, but 184 sits far above the 140 to 145 range where it usually starts. Real-world genius is judged by achievement, and the famous examples, from Newton to da Vinci, have estimated rather than measured IQs. No test measures 184 precisely.
What does an IQ of 184 mean?
A 184 means your result on a timed reasoning test was 84 points above the average of 100, which this site labels Profoundly Gifted. Most tests cannot measure this high precisely. It reflects one test on one day, and it does not measure knowledge or character.
How rare is an IQ of 184?
About 1 in 93 million people score 184 or higher. In the UK that is about 1 person, in the US about 4 and worldwide about 87. About 1 in 240 million score exactly 184. These are bell curve estimates, not census counts.
What is the mental age for an IQ of 184?
There is no real mental age for adults. The idea comes from early ratio tests for children: a 6-year-old with a ratio IQ of 184 would reason like a typical 11-year-old. Today's tests use deviation scores, which rank you against your own age group.
