I see this at multiple levels, simultaneously.
"You're all idiots and a waste of my time" from tech bros being an all too common example.
But it's also the outsiders and newcomers to a field treating its incumbents as some sort of archmage of intellect. (I promise you I'm just as clueless and confused as the rest of us.)
"You just think you're better than us" is something I hear from time to time, but never from anyone I've talked with.
It's shouted at me from throwaway accounts operated by strangers.
And I find that very amusing, to be honest. If I were to correct them, would that not be exercising a perception of superiority--the very false notion I'd be hoping to dispel?
What a conundrum!
