only trust the stuff that has been researched well
It's a laudable precept isergodur, but after reading "New Scientist" magazine for most of my life and seeing tiny studies of patients throwing up spurious results due to statistical anomalies that are a result of poor design or statistical analysis, and reading about
the huge attitudinal bias implicit in accepting funding for all sorts of medical conferences etc...it doesn't leave a lot of research !
Doctors aren't usually good scientists - they aren't properly trained for a start - but sadly they think they are, just like everyone thinks they are an above average driver.
I am inclined to think that the nurses are more likely to know the truth than the doctors, because doctors get the theory handed down from "highly esteemed authorities" - older colleagues whose ideas cannot help but have been shaped when they were young, whereas nurses actually see the reality up close and personal to a greater degree from the word go.
Supposedly there once was a famous English medical school physician used to finish medical lectures with the words, "Half of what I have just told you is wrong. I don't know which half. Go find out !" I think that is a good rule of thumb for most subjects except engineering, including the received wisdom for alternative therapies.
