How are IQ scores for historical estimated?
Not by testing anyone. Each figure on this page is inferred from the documented record — published work, contemporary accounts, verified qualifications — using a named method set out under how we read a number. Every profile shows its own workings.
Which of these historical has the highest IQ?
Blaise Pascal holds the highest estimate in this category at 180–195. That ordering comes from the midpoint of each range and it re-sorts itself as profiles are added, so treat it as a convenience rather than a verdict. The full leaderboard ranks every category together.
How many historical profiles are there?
19 so far, and the list grows as figures are traced and portraits licensed. Browse the rest of the section from all categories, or start at the Celebrity IQ hub.

Get a measured number first. The IQ Metrics assessment is 30 questions and reports on the same 100-mean scale used on every profile here, with a percentile and an ability breakdown. How we score and norm it explains the benchmarking, and average IQ by country shows how the same scale looks across populations.
