I saw a post on r/iamverysmart about an IQ test, which is obviously not reliable, but I also recently learned IQ tests are supposed to be your “mental age” divided by your physical age times 100 (so a kid as smart as a 6 yr old who’s 4 would have an IQ of 150, for example). But the difference between those for an adult would get much smaller, as two years or so is a much smaller difference percentage-wise and an adult’s IQ would always approach 100. So how do IQ tests for adults work?
