Depends upon how I feel about the person and the conversation at hand. Usually, I find them a nuisance. If you don't know wtf you are talking about, shut yer mouth for cryin' out loud! You are wasting my time and your energy.
I looked up "pseudo intellectual." I found a really interesting site:
Pseudo-intellectualism is a social stance. A pseudo-intellectual wants other people to think he's smart. He will work towards that goal in the most economical way possible.
An intellectual will read a whole book, because his goal is to understand the book. A pseudo-intellectual will read the Cliff Notes, because his goal is to convince people that he's read the book. And you don't need to read a whole book in order to make most people think you have. Cliff Notes are more efficient.
An intellectual always wants to know why. His whys are bottomless. Why is it raining? Because there are clouds in the sky. Why are there clouds? Because water condensed. Why did water condense? Etc. He will never tire of this. If you ask him why he wants to know, he'll stare at you blankly. Because, to him, knowledge itself is the goal. He gets a dopamine rush from knowledge. He doesn't understand phrases like "Why does it matter?" "What's the point?" or "What's the practical application?"
A pseudo-intellectual doesn't ask why? why? why? He only asks about things that signal he's one of the smart set. In fact, he rarely asks. He tells.
