Not really. Doctors are part of a very science/research heavy industry so most of the serious research is focused on them but the relatively few sources available on lawyers have the same conclusions about competitive, economic, and intellectual incentives selecting for a very narrow class of people. The really interesting part comes when you expand your outlook beyond the Western research world (which very few metastudies in psychology do, unfortunately) where these results aren't always so clear cut. It appears that a culture such as the one in India or Cuba, which heavily emphasizes education in family life, can have turn a lot of that arrogance into humility.
