• In Mindless Eating, Brian Wasnick cites studies that show that people enjoy wine with expensive labels more than the same wine with cheap labels. Price is a sort of proxy for social proof.
• There was a 20-20 show that showed that people who claimed to enjoy Gray Goose vodka more could not actually tell it apart from Smirnoff in taste tests

I don't know how fuzzy the line is between pretending to enjoy and actually enjoying. There are certainly people who are very good at various degrees of rationalization, and framing their experiences in terms of "ought" theories in order to convince themselves that they are enjoying themselves.

In a Simpson's episode, Lisa goes cross-country skiing while the rest are enjoying downhill skiing, and is trying to convince herself (aloud) that cross-country is the "real" experience.

You also have to separate out the early phases of acquired tastes when people are learning to enjoy things.

And finally there is the attribution error. You may be enjoying one thing and attributing it to another, and lack the self-awareness to tell the two apart.
