“Systematic reviews of controlled clinical studies of treatments used by chiropractors have found no evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain.[8] A 2011 critical evaluation of 45 systematic reviews concluded that the data included in the study “fail[ed] to demonstrate convincingly that spinal manipulation is an effective intervention for any condition.”[10] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain, but the results for acute low back pain were insufficient.[11] No compelling evidence exists to indicate that maintenance chiropractic care adequately prevents symptoms or diseases.[12]”
Well, to be fair, some “doctor doctors” aren’t even doctors.
“Medical Doctors” don’t necessarily have a PhD, but colloquially we call them “doctors”
A doctor is anybody with a doctorate.
Somehow, colloquially, we came to only refer to MD’s ( Doctor of Medicine ) as doctors.
A PhD is just a Doctor of Philosophy. A PhD doesn’t make anyone a doctor more so than an MD or a JD. Yes, even a lawyer is a doctor.
Anybody with a doctorate degree is a doctor. And just for fun, all a doctorate means is the highest degree awarded by a graduate school or other approved educational organization. Feel like I’m getting too technical with this so I’m just going to stop writing this comment.
In Germany, if you are a medical doctor with a PhD, you are addressed as Herr Doctor Doctor.
And if your specialty is the protein filament that grows from skin follicles in mammals, would you be a Haar Herr Doctor Doctor?
