The 5,570 Greatest Geniuses in Human History and Their IQs

Who are the most intelligent people alive? And who were the most intelligent people in history? Many authors have produced rankings based on their own opinions and speculation, while others have attempted to use objective metrics, but without the necessary standardisation.

This work stands apart by eliminating arbitrariness and distortion through the application of an innovative method, based on the concepts of pQI and rIQ, to produce scores on a ratio scale. The method incorporates 208 weighted variables, optimised numerically using SLSQP, with adaptive outlier removal based on multivariate Mahalanobis distance, producing a composite Z-score that correlates at r = 0.978 with IQ.

The greatest scientists, mathematicians, philosophers and inventors from different eras appear together in a unified ranking, based on a robust and accurate model that makes it possible to compare them on the same scale.

For anyone interested in the History of Science, mathematical modelling, giftedness and genius, intelligence and IQ, this is a sui generis work that promises enjoyable moments of leisure, excitement and learning.

More than a ranking, it is a map of human intelligence — a work to consult, discuss, challenge and rediscover for many years to come. The reader is invited to journey across more than 4,500 years of innovative thought from those who shaped our civilisation, uncovering unexpected connections, forgotten talents and figures whose greatness remains astonishing through ideas
