voice teaching, target practice, and the god complex

I've just been listening to Tim Hartford's Ted Talk entitled "Trial, Error, and the God Complex."  Tim reminds us that any problem faced by humanity is far more complex than can be simply "known."  Given the profound complexity of the voice, we face this in voice teaching and research perpetually, yet, we also face the fear of being wrong. This fear leads many in the voice community to accept the God Complex both taking on the God mantle themselves, and distributing it out to others who are "in the know" as our line of defense.  What would the voice world look like if we could release the need to "know", and accept the thing that we are actually quite good at, which is target practice (the equivalent to Tim's "trial and error")?  How would that free us to enjoy, experiment, and seek after new information, and learn to look upon one another with less judgement?
