IQ 88

88 is in the lower half of the average range, 3 points above the 85 edge. In a class of 30 that is roughly 6 people at or below you and 24 above, which is about as ordinary as a score gets.

Scores near the middle of the curve are the most precisely measured, because tests have the most data there. A 88 is one of the more trustworthy numbers an IQ test can give you.

This is the shared result of most of the people you know, from colleagues to friends to family. Nothing about it is a barrier to the things people usually care about.

In daily life a 88 does not show up as a limit or an edge. It means that on fast, unfamiliar puzzles you tend to be a little slower or less accurate than the median adult, by 12 points or 0.80 of a standard deviation.

Where a score like this shows is mainly in speed on unfamiliar, timed problems. Given time, familiar material and a clear goal, people across the average range reach the same answers.

School results in this range depend heavily on teaching, effort and interest. The same score turns up in students with top grades and in students who struggle.

A total of 88 averages several abilities together. Most people are stronger in some than others, and the practical wins come from building around the strong ones:

• Lean on structure. Checklists, notes and routines free up working memory for the hard part of a problem.
• Give unfamiliar problems time. Speed is where average scores differ most, and most real decisions are not timed.
• Play to your pattern. If visual puzzles felt easier than number ones, that is useful information about how you learn.

If IQ follows the standard bell curve, 21% of people score 88 or lower. Here is what that share means across whole populations:

Scoring 88 or lower is about 1 in 5. At 93 or lower it becomes 1 in 3, and at 83 or lower 1 in 8, which shows how quickly the curve fills up towards the middle.

What your 88 could really be. If you retook a well-made test, landing at 83 or at 93 would be unremarkable. That is the difference between beating 12.9% and 32% of people, and short online tests are noisier still.

Which scale was it on? A 88 reported on an SD 16 scale converts to about 89 on the usual SD 15 scale, and one from an SD 24 scale (seen in some Cattell-style results) to about 93. Check which scale your score report used.

Nobody famous has a verified IQ in most cases, and retrospective estimates are only made for a narrow group.

The estimates on our historical profiles run from 115 to 250, so none lands close to 88. Historians only estimate IQs for people who did something extraordinary, which skews the list. It says nothing about what famous people could actually score.

People with an IQ of 88 typically score about 840 on the SAT and about 14 on the ACT composite. Scores vary a lot from person to person, so the range shows where about four in five land.
