Two Russian artists, Vitaly Komar and Alexander Melamid, have set out to demonstrate this concept. They contracted with a public opinion polling company to conduct a survey of popular artistic taste. The first poll targetted Americans, but they have since expanded their pool to the global community. They used the results of the survey to produce paintings that correspond to the reported "preferred" and "least preferred" results.
The people like blue, outdoorsy scenes. (So do I.) Americans like paintings that include lots of water and sky, some wildlife, and George Washington. The Dutch seem to be the only people to prefer abstraction. The Chinese want their paintings to be the size of a wall; the Russians want their paintings to be the size of a television. The paintings produced, of course, are pretty ghastly, although very competent.
The Dia Center hosts the artists' website, which provides more information about the survey, its goals, and letters received by the artists from the general webpublic.
