there are of course exceptions but generally speaking, the ability to be self reflective is a sign of intelligence. if you can't hold a conversation with yourself in your own head, you probably are npc status. if you have the ability to talk to yourself and have cognitive dissonance, you might be extremely focused on a singular issue, which could be good or bad. if you can talk to yourself and lack self awareness, it could be that you haven't taken the time to do it. many intelligent people are prone to getting sucked up into an interest and forget to do basic mental housekeeping.  i personally have a minor god complex. i'll ask questions i don't know the answer to and when i get explanations that don't make logical sense, i assume i'm better than you because at least i know the boundaries of my logic and knowledge, unlike you. this happens a lot.
