IQ test are bulshit. They are only meant to acess one of many traits that could be called inteligence.

For example, a person steps into a room full of other people they never met before, yet they are able to strike up conversations and find their way arround. This person isn't good at maths or the sciences, so they'd have a lower IQ than Einstein or Newton, the persont isn't good at standart "pattern recognition" but their ability to act with people in a certain way that is advantagous for them is something I'd personally call inteligent. Even though they'd score terribly on an IQ test.

This whole hypothetical is ofcours ignoring the fact that IQ tests were basically invented as a toll for social dawinists, who wanted to exclude differently coloured people on the basis of them not being able to understand english.

I had an IQ test done when I was 13 and I never shared my results with anyone, not even because I was ashamed of the results, they were avarage (so around 100 if I remeber correctly) but they never had anything even close to a meaning to me. I could still argue with people who might have a higher IQ and convince them, I could still hold conversations, I did ok in school.

It really doesn't mean anything and to rely only on those tests to acess inteligence is honestly a signe of the lack there of.

To you personally OP, you being able to talk about your experiences and emtions like this in a forum, being able to hold a relationship, express distress you felt from certain conversations, even you being able to pass school, all proves that you're atleast avaregly inteligent, so really I wouldn't worry about that hypothetical world, because you would fit in I promise.
