| There was an interesting study I remember reading along these lines. They took two equivalent classes of pottery students. Group A was told that they'd be graded based on the number of pieces made, while group B was based off the quality of a single submitted piece. Following the given incentives involved, group A made a bunch of pottery, while group B tried really hard at making good pottery. What's interesting is at the end of the class, group A's pottery was better than group B's. Making a lot of pottery without caring about the quality of any individual piece is better at making high quality pottery. The key takeaway I got is that you're generally able to magically become better at things you do a lot of. So if you want to get good at something, just do it more, and results will generally follow. |
The story you're repeating is a parable, published in a book called "Art & Fear" (as sibling commenters have noted).
There is no evidence in that book that it's anything other than a fabrication, argumentation from "just-so story".
I happen to believe the theory, personally. But the ceramics story is not evidence at all that the theory is correct. It's just a bald-faced assertion.
