That being said; a challenge to your statements:
>[. . .] instead we do what we feel is best for us personally, using a fairly emotional and error prone system of judgment [. . .].
My experience has shown that a very cohesive team who like and appreciate each other, but is made of middle-ability individuals is much, much more productive to my measure as the boss than a team comprised of high-ability, but un-cohesive (non-cohesive?) individuals.
Soft skills and the ability to work well together without judgment are both wildly important. In a team of antagonists, it is difficult, if not impossible, to feel comfortable enough to take chances.
Not sure what the challenge is in that statement, but it's in there somewhere.
