About IQ Scores: IQ (Intelligence Quotient) scores follow a normal distribution with a mean of 100 and a standard deviation of 15. Historical IQ estimates for famous individuals are approximations based on their demonstrated achievements, not direct test results. These estimates should be considered illustrative rather than definitive.
Sources and method
Scores on this page use the deviation-IQ scale of the modern Wechsler and Stanford–Binet tests: mean 100, standard deviation 15. Percentiles and rarity figures are computed from the normal distribution. Published tests report full-scale scores only up to about 160 (the WAIS-IV range is 40 to 160), so rarity figures above that level are statistical, not measured.
