I know at least one of these people (IQ 155).

Here is the fundamental problem she has: lower IQ people will deny the obvious even in front of their eyes.

The combined delusion of all these people literally build our world that for her appears like a cheap stupid fairy tale (specially IQ 110-120 people that try to trick lower IQ people for money (advertisement etc)).

She is surgeon and only deals with children: it keeps a lot of the low IQ people at bay. When she is not fixing children, she is riding horses. Much else is just fake to protect her from low IQ people.

These 2 poor souls physically segregated themselves from low IQ people, she did the same... to a less extreme level (accepted to pretend/lie when needed).

If she had seen a big warning sign saying "high IQ hurts", she would probably have had found help and more people to soften the terrible loneliness she experiences.
