FREQUENTLY ASKED QUESTIONS
Who has the highest IQ in history?
Based on historiometric estimates, figures like Alan Turing (170+), Mozart (165+), Leonardo da Vinci (160+), Isaac Newton (160+), Albert Einstein (160+), and Shakespeare (160+) rank among the highest. These are retrospective estimates based on their documented cognitive achievements, not direct test scores.
How are historical IQ scores estimated?
Historical IQ estimates use a method called historiometrics, developed by researchers like Catherine Cox and later refined by Dean Keith Simonton. It analyses documented childhood development, educational achievements, creative output, problem-solving ability, and contemporary accounts to estimate cognitive ability relative to the general population.
Are historical IQ estimates accurate?
Historical IQ estimates are speculative approximations, not precise measurements. Most subjects never took a modern standardized test. Historiometrics can organize evidence about development and achievement, but it cannot recover a clinical score.
What is the average IQ of famous historical figures?
Across our database of 92 historical figures, the average estimated IQ is approximately 149. This is well above the population mean of 100, which is expected since historical prominence correlates with exceptional cognitive ability.
Did Einstein really have an IQ of 160?
Einstein never took a modern IQ test. The estimate of 160+ is based on his extraordinary contributions to theoretical physics, his documented thought processes, and analyses by cognitive researchers. Some estimates place him higher, but 160+ is the most widely cited historiometric figure.
