To answer the OP, yes, I have been told several times in my life by people I'd known for a while, that when they first met me they felt intimidated by my intelligence. It always seems odd to me, because it invariably comes from someone whom I respect as quite bright themselves. The people whom I truly think of as dolts are too stupid to be intimidated by intelligence, they wouldn't recognize it if it bit them.
I don't think I'm all that - I'm painfully aware that there's a lot in this world I don't know - however, it doesn't change my opinion that most people are thickheaded morons (and I am by no means convinced that they possess any gift of natural intuition). So in that regard, yes, I'm smarter than most of the people around me, but by default, not by innate superiority.
