Though I appreciate the discussion of the concept (and is see so little of this type of discussion on forums, so I'm delighted to see it here), there's such a range of quality and ability of the people in both fields that making the type of generalization that was proposed seem a bit like trying to decide what color is a shirt.

I suspect, however, that the very best people in virtually any field are the ones who are the most observant, and that this cuts across everything from drawing and photography to things like farming and selling shoes.
