I argue that "snobbery" is only true when the favored condition actually has some merit of some kind.
The condition described here is more like the kind of cognitive dissonance described in (I think it was) Escher, Goedel, Bach, where the robot insists that one recording of a symphony is more pleasing than another, because of the aesthetic qualitites of the patterns of the grooves in the vinyl discs.
So is the robot a snob, or, deaf to the actual auditory content and unfit to judge by normal human standards?
There are all kinds of people who have nothing to be snobby about, yet act supercilious all the same.
