Surrounded by average people… what’s the likely IQ of your neighbour…?


IQ, the intelligence quotient, is defined as a normal distribution with mean of 100, and a standard deviation of 15. According to James Flynn, people with IQ 70 or less, are mentally retarded, while those with IQ 130 or more, are gifted.

As obvious from the image, you are most likely surrounded by very average people.

The graph below shows the proportions of retardedness, normality and giftedness:
