An IQ of 187 places you in the Profoundly Gifted band — the top 0.000% of the adult population. On a standard IQ distribution (mean 100, standard deviation 15), this corresponds to the 100.0th percentile.

What this score actually means

An IQ of 187 is in the Profoundly Gifted range — the rarefied tier above 145. Roughly 1 in Infinity people score this high or higher. At this level, abstract reasoning, pattern recognition, and inferential reasoning all run several standard deviations above average. The challenge at this tier is rarely intellectual — it is more often social (finding peers), motivational (sustaining engagement with under-stimulating work), and emotional (the asynchronous development pattern common in profoundly gifted individuals).

How rare is IQ 187?

An IQ of 187 or higher occurs in roughly 1 in millions of people. In a typical room of 100 adults, you'd expect about 0 to score 187 or above.

Professions and IQ 187

At this IQ level, most cognitively demanding professions are accessible — physicists (~132 avg), mathematicians (~132), software engineers (~130), surgeons (~127), and university faculty (~126) all cluster nearby.

The limits of a single IQ score

A composite IQ score is useful but it conceals the underlying cognitive profile. Two people both scoring 187 can have very different strengths — one may excel at verbal reasoning and lag at spatial; another may be the reverse. Core Brain decomposes your score across six cognitive axes (pattern, numeric, verbal, spatial, logic, matrix), giving a more useful picture than the single number.

The score is also not destiny. Educational interventions, learning disabilities, sleep, motivation, and time of day all shift measured IQ. Standard error on a single test is typically ±3-5 points. Two tests taken months apart by the same person can differ by 5-10 points without anything meaningful having changed.

Frequently asked

Is IQ 187 good or bad?

An IQ of 187 places you in the Profoundly Gifted range — 100th percentile. It is above the population average and indicates capability in most cognitively demanding work.

Can IQ 187 qualify for Mensa?

Mensa requires an IQ of 130 or higher on Wechsler-scaled tests (98th percentile). IQ 187 qualifies — you would be eligible to join.

How accurate is an IQ of 187 from an online test?

Online IQ tests are calibrated against normed distributions and approximate clinical tests reasonably well for healthy adults under timed conditions. The standard error is typically ±5 points. For high-stakes decisions, only a professional WAIS-IV or Stanford-Binet assessment is definitive.
