I guess, if you want a simple test, the question is always, “What is the finality of what we're supporting?” In art, the finality is not a product or something that is necessarily useful or an object or an invention. It's art, and it's a contribution to advancement of culture.
Sometimes the distinction is not that clear, but usually—I would say 90% of the time—it gives you an indication of how to decide and what the best way is to support one thing or another. It's not that one is good and the other is not; it's more a case of making sure that you give the right support for the right activity for the right outcomes.
