So what are some real practical differences?
Defining the OUTCOME
There are also practitioners that completely reject the evidence-based approach of using critical thinking, observation and experimentation to gain scientific insight into the true nature of reality. I do not consider anybody who rejects this approach a medical practitioner. Anybody who rejects this general approach is in my opinion a plain idiot and a quack. The scientific method is a necessary foundational system of self-optimisation. Without that it is impossible to improve as an individual, as a profession, as a craft or as an art.
Upstream vs. Downstream Interventions
This brings us to the second key difference in my opinion.
May the FLOW be with you!
