Sort of the Dunning–Kruger effect as applied to
sophistication. A cognitive bias that individuals with somewhat limited cultural or worldly experience overestimate their own
sophistication. A smug attitude as related to elegance, good taste, and sensibilities by someone who thinks they are all these things, but in fact are not. A "put on" or show of
sophistication by someone who in fact lacks sophistication.
Jim, who bragged about being a
collector of fine art, stated that Thomas Kinkade was his
favorite artist, thus
exposing that he was pseudo-sophisticated when is came to art.
