Dear Jonathan, I am not trying to prove that the 'establishment' view of reliable evidence is wrong. I still don't understand what the 'establishment' view of reliable evidence is. So how can I possibly be trying to prove that it is wrong? I'm not 'playing around with words'. I am trying to understand their meaning in the context that they are used. So have I misunderstood here Jonathan? Is it the case that you and others believe that anecdotal information from patients and doctors can sometimes provide reliable evidence?
