What a score of 147 would mean
On many modern IQ scales, 100 is the average and scores are spread around it. A score of 147 would sit far above the average—roughly three standard deviations higher on a common scale. If the test were properly standardized for the person taking it, that would place the result among a very small fraction of test-takers.
The number is not a percentage, and it does not mean someone is “47 percent smarter” than average. It is a comparison with a reference group, based on performance on a particular test.
Why the test matters
IQ tests can assess abilities such as reasoning, pattern recognition, and working with information under set conditions. But different tests measure different skills, and scores can be affected by factors such as the test’s design, the conditions in which it was taken, and how it was scored. Without details about the test and its administration, a reported number cannot be independently interpreted with precision.
Nor does an IQ score measure every kind of ability. It cannot, by itself, summarize musical talent, comic timing, business judgment, or the skill of building a public persona. The striking figure is best understood as a claim about performance on an IQ test—not a complete measure of what a person can do.
