Is a Placebo a Sham If You Know It’s a Fake And It Still Works?
October 28, 2016
(NPR) – So placebos have pretty much been tossed in the “garbage pail” of clinical practice, says Ted Kaptchuk, director of the Program for Placebo Studies and the Therapeutic Encounter at Beth Israel Deaconess Medical Center. In an attempt to make them more useful, he has been studying whether people might see a benefit from a placebo even if they knew it was a placebo, with no active ingredients. An earlier study found that so-called “open-label” or “honest” placebos improved symptoms among people with irritable bowel syndrome. And Kaptchuk and his colleagues found the same effect among people with garden-variety lower back pain, the most common kind of pain reported by American adults.
