No, funnily there is no limit. It is just a standard normal distribution with a mean of 100 and standard deviation of 15. You can read more on wikipedia’s ‘intelligence quotient’ under the section ‘current tests’ where you could click on the links to learn more about the mathematics. Setting the mean to 100 rather than zero was probably so people wouldn’t get offended as easily 😂
Isn’t there a hard floor though? IQ would have been such a bummer if they set the average at zero 🤣

Negative IQ would be more than six sigmas away. I don’t think the distribution would hold till tail that far 🤔
I was wring abou the 13 billion. It’s more like 76 billion. But you can reach any number with enough tests.
