I would say that sound methodology comes from your initial training and ongoing education. It is not something that you are born with. There is a small but important difference between being smart and being well trained. Nobody is smart enough or has enough time to develop and apply perfect methodology to each job. This is why experience and education are such huge advantages. It seems obvious but it is worth repeating.
On the whole I agree with Paulinho. Blindly following a procedure without some level of critical thinking is dangerous.
