There's a forum I poke at pretty regularly to try to keep a finger on the pulse of the dumbest parts of the photography-verse. In it there was a recent thread about William Eggleston, and there was a little flurry of the sorts of responses you'd expect from idiots. They're just bad photos (whatever that even might mean - in this context it probably means that they look nothing like bottom-feeder Lifestyle Photos) Snapshots and I don't get it. Not to suggest that everyone should be an Art History major, but 5 minutes on wikipedia would enable pretty much anyone to say something more intelligent along with the I don't like it statement.
Anyways, one of the I don't like it crowd suggested that probably people like Eggleston because they are "primed" to like him. We've heard that he's important, that he's good, so we try to find a reason to like the pictures. This poster phrased it as a dismissal, essentially suggesting that people are "tricked" by the critics and the Art Establishment into liking something that he doesn't like, that is, which is objectively shit.
The thing is, this sort of "priming" is why we like everything. What art do you like? What books do you like? What music? You like it because of all that you have absorbed in this society. You like it because the critics like it (or hate it), and because your Mom likes it (or doesn't) and because your friends like it. This is the nature of these intersubjective experiences, more or less by definition. Art is, literally, good because society decrees it to be good.
Not liking Eggleston isn't a sin, he's not the most approachable photographer ever. Dismissing him as "bad" or a mere maker of "snapshots", dismissing people who do like or appreciate his work as victims of a scam, these merely mark you as an ignorant rube. You might as well fabricate a scarlet R and wear it out around town. It is one thing to disagree with the social consensus, that's perfectly normal and often reasonable. To deny that a social consensus exists, or to dismiss it as irrelevant, is to be a flat-earther.
Also, "priming" is a term of art in psychology which doesn't mean this really at all, but I dare say if we're careful we can get away with the usage here.
