What is Normal IQ Distribution?
IQ distribution follows a normal curve (bell curve), where most people (68%) have an IQ between 85 and 115, close to the average of 100. Only 2% of the population has an IQ above 130 (gifted) and 2% has an IQ below 70. This distribution is consistent across different countries and cultures, being one of the most studied patterns in psychometrics. The standard deviation of 15 points means that approximately 95% of the population has an IQ between 70 and 130.
