There's a theory that seeing something over and over and over will increase your acceptance of that thing. Applied to art, the idea suggests that what we think of as "good art" is actually just the stuff that we've seen a bunch of times. Which is sort of depressing. But here's some good news: There's evidence that this theory isn't true (at least, not always). A recent study found that people exposed to Thomas Kinkade paintings liked his work less and less the more often they saw it.
