Richard Feynman
Where 125 Falls on the IQ Scale
What Is Richard Feynman's IQ?
Richard Feynman's IQ is estimated at approximately 125, placing them in the Above Average range. Richard Phillips Feynman was an American theoretical physicist. He shared the 1965 Nobel Prize in Physics with Julian Schwinger and Shin'ichirō Tomonaga "for their fundamental work in quantum electrodynamics (QED), with deep-ploughing consequences for the physics of elementary particles".
For context, an IQ of 125 would put Richard Feynman in approximately the 95.2th percentile of the global population. The average IQ is 100, and a score above 130 is generally considered "gifted," while 145+ is typically classified as genius-level.
Evidence Behind the Estimate
Unlike some figures with formally disclosed IQ scores, most celebrity IQ estimates are compiled from academic records, biographical accounts, performance data, and expert analysis. Estimated
- Won the Nobel Prize in Physics in 1965 for quantum electrodynamics
- Known for the "Feynman Technique" — explaining complex ideas in simple language
- Contributed to the diagnosis of the Challenger space shuttle disaster in 1986
- Self-taught himself trigonometry, algebra, and calculus before college
- Assembled safes at Los Alamos for fun to demonstrate security vulnerabilities
How Does Richard Feynman Compare?
With an estimated IQ of 125, Richard Feynman falls into the Above Average classification. Scores in this range represent solid above-average intelligence, associated with strong academic performance and professional success.
What Does This IQ Score Mean?
Psychologists generally agree that IQ captures a meaningful slice of cognitive ability — particularly in areas like abstract reasoning, pattern recognition, and verbal comprehension — but it's far from a complete picture. Many researchers emphasize that above a threshold of around 120–130, raw intelligence increasingly gives way to creativity, grit, emotional intelligence, and circumstance as determinants of real-world success.
Richard Feynman's accomplishments in scientists suggest a cognitive profile that pairs well with their estimated IQ — demonstrating not just raw intellectual firepower, but the drive and focus to convert it into meaningful output.
