“Sooner or later we’ll get rid of the term,” he says, and talk more specifically about each of its components. “I see the placebo effect as a kind of loose family of different phenomena that are just yoked together by this term,” says Franklin Miller, a retired NIH bioethicist who has edited a volume on the subject. And that includes rituals, symbols, doctor-patient encounters.”Īnd it’s not just one thing. The placebo effect is a surrogate marker for everything that surrounds a pill. These days, placebo - Latin for “I shall please” - is much more than a pious fraud.Īs Ted Kaptchuk at Harvard, who is regarded as one of the world’s leading experts on placebo, put it to me in a recent interview, the study of the placebo effect is about “finding out what is it that’s usually not paid attention to in medicine - the intangible that we often forget when we rely on good drugs and procedures. “One of the most successful physicians I have ever known has assured me that he used more bread pills, drops of colored water, powders of hickory ashes than of all other medicines put together,” Jefferson wrote in 1807. Thomas Jefferson himself marveled at the genius behind the placebo. It’s a family of overlapping psychological phenomena.īelief is the oldest medicine known to man.įor millennia, doctors, caregivers, and healers had known that sham treatments made for happy customers. Most instructively, the science finds that since we can’t separate a medicine from the placebo effect, shouldn’t we use it to our advantage? There is no one placebo response. And it could also potentially allow us to one day prescribe smaller doses of pain drugs to help address the opioid crisis currently ravaging America. The new science of placebo is bringing new understanding to why alternative treatments - like acupuncture and reiki - help some people. Scientists have been studying this incredibly complex interface in great detail over the past 15 years, and they’re finding that sugar pills are stranger and more useful than we’ve previously imagined. “It’s at the precise interface of biology and psychology,” and is subject to everything from the drug ads we see to our interactions with health care providers to the length of a clinical trial. “The placebo effect is the most interesting phenomenon in all of science,” Mogil says. Placebos are growing in strength in antidepressants and anti-psychotic studies as well. And it’s not just growing stronger in pain medicine. What this showed was not that the drugs were getting worse, but that “the placebo response is growing bigger over time,” but only in the US, explains Jeffrey Mogil, the McGill University pain researcher who co-discovered the trend. When researchers started looking closely at pain-drug clinical trials, they found that an average of 27 percent of patients in 1996 reported pain reduction from a new drug compared to placebo. If those who actually took the drug report significantly greater improvement than those on placebo, then it’s worth prescribing. At the end of the trial, the two groups are compared. In these trials, neither doctors nor patients know who is on the active drug and who is taking an inert pill. Over the last several years, doctors noticed a mystifying trend: Fewer and fewer new pain drugs were getting through double-blind placebo control trials, the gold standard for testing a drug’s effectiveness.
