So I don’t know if this answers your question, but there’s my two cents for you.
It does! This is precisely the kind of stuff that I’m interested in! I agree with you, in that it’s possible to think wrong thoughts even with a higher IQ. I see IQ as the speed of thought, and you can very quickly arrive at wrong conclusions. Similarly, if there’s a thought that your skill tree hasn’t unlocked, then you’re left with thoughts that are maybe not ideal for a particular situation, thoughts that could make someone “overcomplicate things unnecessarily” or “make dumb mistakes”, as your dad or anyone on planet Earth would.
I think it’s especially hard to isolate IQ when there are many thoughts or behaviors that we don’t typically associate with high IQ. “Ah yes, the violin is a sensible instrument for a learned man” or whatever people may think. That’s partly why I asked my question. If someone leads a life not typically associated with a high IQ and yet have a high enough IQ that manifested in their life, how did that look like? Of course, I’m not looking for wild stories. I’m looking for genuine stories, and I’m glad that I got an interesting answers like yours!
How come?
