I can't speak to other professions, but I know for mechanical engineering if you asked 50 engineers what they thought the best solution to a problem was they'ed give you 50 different answers. Of course if you got them all together in a room, probably 40 of them would say "oh that's a much better idea" right away, and a few more would as well after a bit of back and forth. Still, you'd probably be left with three or four proposals, each with a few die hard proponents and detractors. I'm sure any profession that it takes years of training to practice probably comes with enough complexity that broad consensus becomes generally unachievable.
