What does an IQ of 140 mean?
An IQ of 140 is exceptionally high, reached by fewer than 1 in 250 people. It is the score popularly tied to the word "genius".
A 140 sits more than two and a half standard deviations above the average. It places you in roughly the top 0.4% of the population, well into the "very superior" band.
Although 140 is often labelled "genius level" in popular culture, most psychologists avoid that word. Real-world genius involves creativity, persistence, and original output, none of which an IQ test measures directly.
What an IQ of 140 does not tell you
A score this high from a quick online test should be treated as a rough estimate, and free tests can run high. Even a verified 140 describes test performance, not accomplishment. History is full of high scorers who achieved little and modest scorers who changed the world.
