7. I suppose this is always the case as our knowledge advances

What was considered best 20 years ago may be second best or even downright harmful today. Maybe 300 years ago, doctors were considered negligent if they didn't apply leeches and drain blood in many cases where later we figured out that was not such a good idea.

Knowledge is one thing, training is another. Knowledge may allow for nuance. The second best approach may become in many cases, or even more appropriate in certain exceptional cases.

But when training, there's a tendency to teach "the" protocol and dismiss any deviation as simply wrong and substandard and likely negligent and damaging. It simplifies training at the expense of real learning.

Institutionally, they don't want a lot of "dr. House"-type people running around creatively ignoring protocol, with possibly better outcomes, though more likely, many more disasters.
