In my case, I heard about a man with an IQ of 350+, but for some reason he left the country in an unknown direction with his wife and children. Lived like an ordinary person, did not stand out in any way, worked at an ordinary job, I don’t remember which one, but definitely not a teacher, It was a manual profession.
No IQ test is going to measure that high. A lot of the tests, while not perfect, are designed to target within 2-3 statistical deviations around the average intelligence, with a typical standard deviation of 15 points. So, if anyone tests above 145 or under 55, the test is going to be inaccurate. At that point, you’re only dealing with 0.1% of the population and the number is just a pissing match.
That said, just because someone has a high IQ score doesn’t mean they’re great at everything else. Autism seems to run higher in this group than average, but it is likely because some parts of the spectrum of autism helps with taking these sorts of tests. Very smart people can still make mistakes, be ignorant of certain subjects, and have personality flaws like average people.
For instance, medical doctors are generally considered very intelligent, but they are very bad with money.
