I have managed many people in industries that attract low IQ (70-90) workers. I also know a lot of high IQ people since I went to a gifted high school.

I'm not a psychiatrist, but I believe the low IQ have WAY higher rates of anxiety, depression, and other mental disorders, but almost none of them are diagnosed. Their lives run without much thought or planning so they often end up in very stressful situations. Sometimes they don't even realize that something is wrong or not normal. Or even if they do manage to figure that out, they cannot describe what they are feeling or communicate effectively which can be stressful in itself.

I still think high IQ people have mild to moderately higher rates of mental disorders than normal IQ people, but with low IQ I think it's massively higher.

If one does not realize it and thinks it's normal, is that better or worse? Maybe working a deadend job your whole life is easier when you don't realize there's better stuff out there even for you.

"Ignorance is bliss" comes to mind.
