Grigori Perelman
Where 190 Falls on the IQ Scale
What Is Grigori Perelman's IQ?
Grigori Perelman's IQ is estimated at approximately 190, placing them in the Extraordinary Genius range. Grigori Yakovlevich Perelman is a Russian mathematician and geometer who is known for his contributions to the fields of geometric analysis, Riemannian geometry, and geometric topology. In 2005, Perelman resigned from his research post in Steklov Institute of Mathematics and in 2006 stated that he had quit professional mathematics, owing to feeling disappointed over the ethical standards in the field.
For context, an IQ of 190 would put Grigori Perelman in approximately the 99.9999th 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
- Made significant contributions to their field requiring exceptional analytical ability
- Published peer-reviewed research demonstrating mastery of complex subject matter
- Academic background reflects extraordinary aptitude in technical disciplines
- Demonstrated ability to synthesize complex information and generate novel insights
- Their work continues to influence the field decades after initial publication
How Does Grigori Perelman Compare?
With an estimated IQ of 190, Grigori Perelman falls into the Extraordinary Genius classification. This is a rare cognitive level — only a tiny fraction of the population ever scores this high on standardized assessments.
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.
Grigori Perelman'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.
