I understand is that you believe that the work of a doctor can be codified into simple individual skills and relatively clear decision paths. In my experience, even people with no formal training can pick up useful medical reflexes, as evidenced here on Quora. Furthermore, many believe that by reading guidelines and applying medical decision algorithms you are as useful, or even better, than a doctor. However, the real skill comes with the part that cannot be put down on paper. You see, the part that you can find in guidelines, research papers, and textbooks is the obvious part, the baseline. People mistakenly assume that by acquiring this kind of knowledge, which is a lengthy process if you look at the volume of the stuff, you are a good doctor. This is false. The hard part is actually realizing that practicing medicine is a work of interpretation, in the sense that you have to apply rigorous, formal knowledge onto a fuzzy problem, a patient that does not necessarily come with hard measurements or even with clear objectives.
