'Anyone who [...] uses critical judgment and appropriate tools to make evidence-based decisions'

Except for the experimentation part, that could describe a lawyer. Which begs the question,

Where does it go wrong?

Why do people from an evidence-based career become embroiled in the kind of back[stabbing/scratching] politics that seems to be the norm today? And how can it be fixed?

Experimentation is mandatory to conduct Science. You need to be able to form theories or hypotheses from data or observation, and then conduct a controlled experiment to validate your point. There can be no science without validation and repeatability.
