IQ 152

152 sits 7 points past the three standard deviation mark and 8 below 160, where most tests top out. You would outscore 99.97% of people.

The Triple Nine Society's top 0.1% line is about 146 on this scale, and 152 clears it. As with any society, membership needs a supervised test, not an online result.

People this rare can find it takes effort to meet intellectual peers. University departments, clubs and communities built around hard problems help.

People who score around 152, and the teachers who work with them, often describe some of the following. Treat it as a set of possibilities, not a profile:

• Interests can be intense and deep, sometimes at the cost of everything else.
• It can be hard to judge what is obvious to other people, so explaining clearly takes practice.
• Perfectionism and overthinking come up often in first-hand accounts.

Major adult tests are normed on samples of a couple of thousand people. In a 2,200-person norm sample, the bell curve expects about 0.6, less than one person, at 152 or higher, so the top of the scale rests partly on extrapolation.

Short online tests, including ours, are best at telling you roughly where you are. Treat a 152 from one as "well above 140" rather than an exact figure.

Scale matters too. If your 152 was reported on an SD 24 scale, it is about 133 on the usual SD 15 scale, and on an SD 16 scale about 149.

On a bell curve with a mean of 100 and a standard deviation of 15, about 0.026% of people score 152 or higher. Applied to whole populations:

An IQ of 152 or higher is 3.3 times rarer than 147 or higher, and 157 or higher is 3.6 times rarer again. At this point on the curve, each extra point makes a score about 28% rarer.

What your 152 could really be. Even a good supervised test has a margin of error of roughly 5 points either side. A true score anywhere from 147 to 157 would be consistent with a 152, which spans the 99.91st to the 99.99th percentile. Short online tests have wider margins.

Which scale was it on? Score reports do not always say. On the common SD 15 scale your 152 stands as it is. If the report used SD 16 it equals about 149, and if it used SD 24 about 133. The percentile follows the converted number.

Scientists, composers and philosophers often receive estimates in this range. These sit near 152. Every figure below is a retrospective estimate, not a measured score. Open a profile to see the evidence and how confident anyone can be.

Our degree, university and job profiles carry rough IQ benchmarks. These are the ones within a few points of 152. The education figures are derived from admissions-test averages, not from IQ testing.

Nearby scores and the round-number landmarks, so you can see how quickly the percentile changes around 152. Every row links to that score's page.

People with an IQ of 152 typically score about 1600 on the SAT and about 36 on the ACT composite. Scores vary a lot from person to person, so the range shows where about four in five land.
