Indeed, rightly so. But first, I didn’t ask for addresses or phone numbers: why did you add those into the example?
That said, I agree that doctors aren’t going to give out patient information willy-nilly. What they are going to do is (and I write this having worked for six months in an office that managed clinical research studies) keep charts that other physicians have access to; design double-blind, multi-institutional, randomized studies; provide all relevant data to other qualified physicians who are examining their claims; work closely with a statistician to verify that their claims are statistically valid; and so forth.
Do you agree that this is a more rigorous process than [paraphrased], “I have friends who are scientists and who have witnessed miracles”?
Given that the process for documenting a medical claim is rigorous, with multiple checks in the system to prevent fraud, I think it is reasonable for me to put a moderate amount of trust in such medical claims (I say moderate because, for example, some pharmaceutical companies have the horrifying habit of suppressing research that reflects unfavorably on their products).
Well, I’ve not looked for peer-reviewed journals lately. When I lived in Chapel Hill, I or anyone could head over to the medical library on campus and look up almost any medical article you could imagine. That was part of my job.
But evidence comes in layers. If someone whom I trust–who has demonstrated rigorous thinking in other areas–says to me, “You should check out Journal of Neurophysical Research, Vol XVII, pp 21-28: there’s an article therein on spontaneous remission of medulla carcinoma amongst Jehovah’s Witnesses that provides convincing evidence of the power of prayer,” then I might swing by the library next time I’m in Chapel Hill and take a look at it. In other words, if a person has built up trust with me, I’m willing to do more work to get to see their evidence.
Once I see the article, I’ll look at several things:
- On a close reading of it, does it seem to this layman that the researchers reached their conclusions carefully and soundly?
- What are other scientists saying about this research? If criticisms are being raised, what are the natures of these criticisms? Do they seem to this layman to be reached carefully and soundly?
- What are other scientists finding when they replicate the study?
and so forth.
You raise a fair point that peer-reviewed studies are influenced by politics and so forth. That’s unfortunate, but so it goes. The influence isn’t, in my experience, overwhelming: I’m pretty sure I’ve seen peer-reviewed articles discussing the effects of prayer on health. And until someone proposes a superior method of disseminating information about such phenomena, I think it may be the best we’ve got.
In the end, though, while I can say the form in which I prefer the evidence to arrive, I can only say what’d be sufficient: I’m not saying what’s necessary. If cosmos or anyone has evidence in a form other than a peer-reviewed journal, I invite him or anyone to put it forth, and we can evaluate it on a case-by-case basis.
The fewer specifics there are, though, the more skeptical I’m going to be about it: and I’m pretty much going to dismiss any vague friend-of-a-friend case as wholly unconvincing.
