I'm not 100% sure how accurate this is. My IQ is somewhere in the 135-140 range, and while I can't stand most people, there's a certain kind of person that I just can't get enough of and which is hard to explain. Many (but not all) of these people are neurodivergent, and most (but not all) are awkward, shy, and/or geeky.
To be completely fair I'm probably not quite at the level of "very intelligent" that they were talking about, but I'm not necessarily happier alone. I'd rather be alone than be with with average, conventional NT people, but I'd rather be with neurodivergent, awkward, shy, or nerdy people than be alone.
