Cargo Cult coaching?
Why do we do things the way we do?
Interesting, it applies to a lot of fields (all of them?!) - People do things because they've seen them done, not necessarily becaise they understand the reasons why or how they work.
As a coach, it's important not just to "do" but also to understand why we do what we do. It's ok to copy/learn from other programs, disciplines and coaches, but ONLY if we know why and how - or at least, have some understanding of the method. Not everything in coaching is clear cut and often the "evidence base" is pretty flimsy, but we must strive towards greater understanding of what we do, why and how it works (or doesn't!).
Coaches are not scientists, we're engineers. We apply the best available science, mix in some gut feeling and experience where the science is lacking, and run with it to build bridges. We need to understand science much as an engineer does, we have to be able to speak the langauage and ask the right questions (see this : http://startingstrength.com/index.php/site/exercise_science_presentation_2013_part_i as an example of how to read and question ex phys papers). We're not scientists, but we have to think like them sometimes, and call them if they're making mistakes. It happens, a lot. A lot more than we'd like!
