What Does an IQ of 190 Mean?
An IQ of 190 is among the highest ever attributed to any human. Isaac Newton and Garry Kasparov are estimated near this level. At approximately 1 in 1 billion, perhaps 8 people alive today have this cognitive ability. Standard IQ tests are completely incapable of measuring at this height.
An IQ of 190 places you at the ~100th percentile, which means you scored higher than approximately ~100% of the general population on a standardized intelligence test. This score falls into the Unmeasurable range on the IQ scale. With a rarity of 1 in 1 billion, this score is uncommon and indicates strong cognitive abilities.

Who has a 190 IQ?
Garry Kasparov (~190, tested) and Isaac Newton (~190-200, estimated) are most commonly cited. Among living people, Kasparov has the most credible claim to a verified score near this level.
What would 190 IQ be like?
Cognitive processing fundamentally different from virtually all humans. The gap between 190 and average (100) equals the gap between average and an IQ of 10. Most people simply cannot comprehend what thinking at this level entails.
