David Gorski, MD, PhD, has written an outstandingly insightful piece on the Science Based Medicine Blog titled "When impressive science fails to impress patients" He touches on salient points as to why some patients may ignore scientifically supported recommendations regarding treatment which I believe also has relevance to those who will accept the pseudoscientific treatment methods of certain fringe elements.
This article should provide sufficient insight on how best to arm ourselves to approach patients who may be considering certain unreasoned approaches of Complimentary Alternative Medicine (CAM) as opposed to the effective and scientifically based approaches that may be recommended.
I look forward to further discussion in how the principles outlined in Dr. Gorski's article may be utilized.
