Are relatively unintelligent people aware of their lack of intelligence?

I’m not talking about those with an actual intellectual disability, here. This is just about people who are… not-so-smart. Do they know they’re not? I’ve always wondered if I’m actually as smart as I think I am (reasonably smart, but no genius)... would I know if I wasn’t?

Would the not-so-smart individual recognize a higher level of intelligence in, say, a friend? Would they go out of their way to bounce their thoughts off the more intelligent friend, or go it alone? I guess what I’m wondering is if one in such a position would seek help and guidance with things that require complex thought, or does it simply not occur to them. I swear, I’m not trying to sound condescending… I’m having trouble wording this well. Maybe I am not so smart after all!
