Eight fallacies about contemporary art, of which the two that I run into most often from non-art people are:
Value is completely subjective.
No it’s not. There are methods of evaluating art, and just because viewers respond differently doesn’t mean they don’t exist. Unresolved aesthetic choices and lazy conceptual practice won’t receive a pass from me.
Anyone could do that.
A sentiment typically refuted with the argument, “But you didn’t.” A more common version of the myth circulating art circles, “It’s too easy” completes itself with “to take a compelling photograph,” or “to make a good collage.” In each case, the viewer’s actually complaining that it’s too hard to separate the good from the bad. There’s no easy answer to this dilemma, except to look at enough art to develop a mature eye.
