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.
As others have said IQ tests are more about socio-economic factors than brain power.
Maybe this is what you’re looking for.
I live in the US. the “traditional” age most get a bachelor’s degree is at age 22. Though that is just not the case really, but that is another discussion.
I have met two people who got bachelor’s degrees prior to turning 18. Both were women. One got her degree at 16 and the other at 18.
Both are wickedly intelligent, they are geniuses and think of things that just blow my mind. They make connections on things that make my head spin. I really enjoy talking to both, though I have to admit they are just on another plane of thinking.
The thing that surprised me the most, about the one I have interacted with the most, is that she is a well rounded and a totally normal 20 something year old person. I only found out about her mind and history as I asked her if she was in undergrad. I was talking to her and her mom, and her mom chuckled and told me when her daughter graduated so naturally I was interested.
Here is the thing. For both of them their situation kind of sucked. When you were 12 years old where you hanging around a bunch of college kids? Nope
When you are 16 you should be with your peers and hanging out doing teenager stuff. College kids are past that and they both never really did high school.
Also letting a 14 year old wander freely on a college campus is not advisable. So they missed on typically high school things.
I asked them why they went to undergrad so early and it was because they were failing our of high school as they were totally bored with what was “see spot run” stuff to them.
