Christopher Hitchens IQ: 150 (estimated)

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.
