Every 15 points of IQ is 1 standard deviation from the mean. So 210 is 7.3 standard deviations away from 100. Just 7 standard deviations away from the mean mea

Every 15 points of IQ is 1 standard deviation from the mean. So 210 is 7.3 standard deviations away from 100.
Just 7 standard deviations away from the mean means that you would expect only 1 in 780 billion from a population.
Given that this is far more than the number of people on Earth: No, no one has an IQ of 210.
- LyndsySimon 7y agoWell, to be fair, it’s only “highly unlikely” that anyone on Earth has an IQ of 210. Given that seven sigma deviation should occur one time in 780 billion and that there are ~7.8b people on Earth today, then there is a ~1% chance of a person with an IQ of 210 being alive today :)
