Listen, I'm a doctor. Everything I do since I left medical school, every decision I've made in my career, has to be backed by iron-clad evidence. Rarely the evidence is either scanty or anecdotal, but you caveat that into your decision making. For every other decision, I need to document why I've done x rather than y and be able to justify my decision making under professional scrutiny through pointing out an evidence base, whether that be in a morbidity & mortality meeting or to a coroner.
Do my patients care? The hell they do. They ask 'why x?' So I sit down, gird my loins, and start gently and in as much idiot-proof language as I can muster to explain what the evidence base is, how the trials worked, what the conclusions were, how that has led to various guidelines being laid down on managing their condition.
Before 5 seconds are out, the eyes glaze over - they've lost interest. It's pointless. They don't respond to, nor are they interested in he evidence base. They respond to anecdote, emotion, personal experience, what they perceive to be empathy.
And trying to reason with people who have what we in our profession term 'fixed ideas' is well-nigh impossible. You won't win by pointing out an evidence base, because their point of view isn't rational - it's based on emotion rather than reason. They're two entirely different paradigms. It's a fruitless pursuit.
