๐Ÿ’ก How IQ Percentiles Work

IQ scores follow a normal (bell curve) distribution with mean 100 and standard deviation 15. A percentile tells you what percentage of the population scores below your IQ. IQ 100 = 50th percentile (exactly average).

Key benchmarks: IQ 85 = 16th percentile, IQ 100 = 50th, IQ 115 = 84th, IQ 130 = 98th (top 2%), IQ 145 = 99.87th (1 in 741). About 68% of people score between 85 and 115.

IQ 120: 91st percentile โ€” higher than 91% of the population. Classification: High Average. Rarity: about 1 in 11.
