What Does an IQ of 140 Mean?
An IQ of 140 is often cited as the threshold for genius-level intelligence, placing you at the 99.6th percentile. Only about 1 in 261 people score this high. At this level, cognitive processing is markedly faster and more complex than the vast majority of the population. People scoring here can hold multiple abstract concepts simultaneously, identify deep structural patterns, and solve novel problems with remarkable speed. However, genius-level IQ does not guarantee achievement — history is full of both celebrated geniuses and brilliant individuals who led quiet, ordinary lives.
An IQ of 140 places you at the 99.6th percentile, which means you scored higher than approximately 99.6% of the general population on a standardized intelligence test. This score falls into the Genius-level range on the IQ scale. With a rarity of 1 in 261, this score is uncommon and indicates strong cognitive abilities.
