Aren't the best mathematicians the best at solving the hardest problems? I don't see how you can argue this without assuming an arbitrary scale for being "good" at something.

It can be simultaneously true that a group of not very good at something and that that group is the best at doing something.

		As I said, I don't think so as long as you derive your scale of difficulty from the domain itself.
