Wolfgang Amadeus Mozart IQ: 165 (estimated)
Wolfgang Amadeus Mozart's IQ is estimated at 165. This is a widely-cited estimate based on Wolfgang Amadeus Mozart's body of work and historical accounts — not a verified, administered psychometric test score. An IQ of 165 would place a person in the top 0.001% of the population (roughly 1 in 136,176).
Important note: Wolfgang Amadeus Mozart's IQ figure of 165 is an estimate. It comes from historiometric analysis (most prominently Catharine Cox's 1926 study of 300 historical geniuses), childhood ratio-IQ testing, or post-hoc assessment of biographical achievements — not from direct clinical IQ measurement.
Where the 165 estimate comes from
→Pause. Find out YOUR IQ before you keep reading.Catharine Cox's 1926 study The Early Mental Traits of Three Hundred Geniuses estimated childhood IQs for historical figures based on biographical evidence of precocity — age of first reading, age of first publication, mastery of subjects ahead of peers, and so on. Cox's method has been criticized for systematic upward bias but remains the most-cited source for pre-modern figures.
What the score implies — and what it doesn't
→Curious how YOU score? 20-min calibrated test.An IQ of 165 is in the Profoundly Gifted range — top 0.13% or so. Capable of mastering arbitrary abstract subjects with comparatively little instruction.
Wolfgang Amadeus Mozart's achievements in Composer reflect more than raw IQ. The pattern across high-achieving figures is that cognitive ability gets you into the game; the variables that determine outcomes from there are conscientiousness, sustained focus, time-on-task, mentorship, environment, and a tolerance for the social isolation that often accompanies deep specialized work.

The limits of celebrity IQ estimates
→Knowing about IQ ≠ knowing yours. Take the test.- Historiometric estimates like Cox's are biographical inference, not measurement. Catharine Cox herself rated the reliability as "I" through "IV"; many figures are rated "III" or "IV" — weakest evidence.
- Childhood ratio-IQs (mental age / chronological age × 100) systematically inflate scores compared to modern deviation IQ. A 1900-era child labeled "IQ 200" would likely test 140-160 on a modern WAIS.
- Self-reported figures from public figures are essentially never independently verifiable.
- Achievement is not pure intelligence. The correlation between extreme achievement and pure IQ peaks around 130-140; above that, conscientiousness and circumstance dominate the variance.
