IQ is a comparison of your test results to the results of people your own age. The average IQ is 100. If you gave 1,000 people a really hard test, your results would look like this: The higher the graph goes, the more people who have achieved that score.
If you take the worldâs population at 7.4 billion people, then statistically the one smartest person in the world would have an IQ at the 99.999999985th percentile which would be equivalent to test score of 194 or 195 (SD=15). However, there is no test which can reliably measure intelligence at that level.
