There has been a large uptick in interest about the so-called placebo effect, mostly from the complementary and alternative junk medicine (CAM) crowd. Evidently, they feel that being equivalent to doing nothing is good enough to be real. A recent article in the Wall Street Journal, Why Placebos Work Wonders, is indicative of this recent pro-placebo point-of-view.
What exactly is the placebo effect? The definition is often misused, implying some beneficial effect from a sugar pill or sham treatment. But in medicine, a placebo is actually a failure. If a new pharmaceutical, procedure or medical device shows no difference in efficacy compared to a placebo, then it is rejected. But the CAM-pushing herd thinks that proves its a success when one of its potions and lotions is equivalent to a placebo. What? A failure of a modality in evidence-based medicine is somehow converted into a successful product in the CAM world?
