Who's IQ is 500?

There’s No Such Thing as an IQ of 500

Every now and then, someone throws around a number like “IQ of 500” like it’s a real thing—maybe as a joke, or to describe a genius-level mind. But here’s the truth: an IQ score of 500 doesn’t exist. IQ tests are designed with a specific range, and the highest possible scores usually top out around 160 to 200, depending on the test.

The average IQ is set at 100, with most people scoring between 85 and 115. A score of 140 or above is generally considered genius level. Only a tiny fraction of the population hits that mark. So if someone claims to have an IQ of 500, they’re either wildly exaggerating or misunderstanding how IQ works.

IQ tests aren’t perfect. They measure certain types of reasoning, logic, and problem-solving skills—but not creativity, emotional intelligence, or practical know-how. Even the highest-scoring individuals in history, like William James Sidis or Marilyn vos Savant, didn’t come close to 500. Their estimated IQs were in the 190–200 range, which is already extraordinary.

The idea of a 500 IQ might sound impressive, but it’s more science fiction than fact. Intelligence is complex and multi-dimensional. Reducing it to a number is helpful to a point, but no single test can capture the full scope of human potential. So while we may marvel at brilliant minds, let’s keep the numbers grounded in reality.
