If you read the Book on Checklists (which I HIGHLY recommend to everyone) its filled up with examples of a) people getting consistently saved due to checklists and b) trained professionals not wanting to bother with such a mundane thing. Most of these actually care about their patents still.

Also in the book was an example of a baseball team figuring out how the standard scoring methods are slightly off, finding a better one and then buying up undervalued players. The more I look, the more examples of professionals ignoring sound methods to be reliably more successful I find and so I think opportunities for un-biased action are everywhere. But many don't really lead to that much more success.
