Should we require all medical doctors to have had ebola in order to offer treatment for ebola?
No, but we should require that they have the most up to date knowledge about treating it, not a guess that the ebola patient just needs chicken soup and bed rest.
Must all surgeons have undergone at least one amputation in order to perform an amputation?
Unless it's a dire emergency, they should have at LEAST the medical knowledge to understand the implications of removing a limb, and it would be even better if they'd at least assisted with the procedure before attempting it on their own. Or would you be okay with Billy Bob the backwoods surgeon coming at you with an ax and saying, "cool! I always wanted to do an amputation!"?
What about cancer? Must a cancer doctor have HAD cancer in order to advise patients with cancer?
No, but they should at least be knowledgeable in that field of medicine. As someone with an incurable cancer in his 14th year with ongoing treatments involving chemo, monoclonal antigens, a stem cell transplant, numerous transfusions, regular blood work, CT scans, PET Scans, etc., etc., etc., I can tell you that I want someone who KNOWS as much about the current treatments and so forth as possible. I'm not interested in having someone who only has guesses.
If the doctor that first diagnosed what was wrong with me already in stage 4 and nearly dead as non-Hodgkins cancer had "guessed" instead that I just has a bad cold, I wouldn't be here to write this. So yeah, it's kinda important that people speaking from a position of authority on a subject actually HAVE the knowledge and experience with that subject, not just guesses.
My favorite recent issue is the Nikon D600 oil flinging issue. Loads of new owners claiming it did not happen. Swearing up and down that the D600 oil flinging issue was a myth.
Turns out, according to Thom Hogan's research that it takes about 4,000 actuations to occur, and from then on it tends to re-occur worse than on as he put it, any Nikon D-SLR he has ever used.
Interesting. Describe his "research method". I bet it was more than just a guess based on what he thinks due to his vast knowledge in general, which seems to me the actual problem up for discussion here.
If someone wants information about the Speedotron Brown Line, should I give out the advice as if I'm an expert on it, even though I've never actually owned or used them, or should I just keep my trap shut and wait for you to come along and give the definitive answer? More importantly, when you don't notice the thread and question so you don't answer, but I DO answer with BS info that's just plain WRONG, is that a good thing, or a bad thing? And not just for that OP, but for anyone else who reads the thread and says to themselves, "gee that Buckster guy sure seems like he knows what he's talking about, and he's been on this forum a long time, and his positives are pretty high - it must be true, so I'll go with what he said."
In my mind, those are the issues under scrutiny here.
