Placebo - covers

Several decades ago, the proponents of so-called CAM promised that if only their preferred if unconventional treatments were properly tested medical science would discover how effective they are. “Effective” (or more precisely, “efficacy”) has a specific definition in medical science – it means that a treatment has been found to perform statistically significantly better than placebo in a blinded controlled trial. Several decades and thousands of studies later, the most popular CAM modalities (homeopathy, acupuncture, reiki, manipulation for medical indications, and more) have been shown to be no more effective than placebo. This means they don’t work.
