Placebo Nation: Just Believe
This is sort of old news to me, but will be new to many. In the book I wrote (but haven’t yet published) about the use of visualization to improve health, I pointed out that the placebo effect should be called the miracle effect. As this article from Newsweek, via a friend, demonstrates.
Placebo Nation: Just Believe
It’s not that medicines are ‘crummy,’ but that placebos are so powerful. It’s time scientists learned why.

When you write about science, there is no shortage of topics that incite the wrath of readers. Climate change. Evolution. Racial differences in IQ. But say that dummy pills with no pharmacologically active ingredients—placebos—are about as effective as antidepressants in treating depression, and watch out. People are incensed at the very thought that the (often expensive) meds they rely on might be 21st-century versions of the magic feather that Dumbo, the flying elephant, was told would make him airborne. It was only when Dumbo dropped the feather he was clutching in his trunk while in free fall, and started flapping his ears, that he grasped that his powers actually came from within, allowing him to fly.
No one is saying “positive thinking” can cure cancer, or that patients should throw out their pills, let alone that illnesses that respond to the placebo effect are “all in your head”—imagined. But there is no denying the drumbeat of studies on the therapeutic power of placebos. Over the years they have been shown to relieve asthma, lower blood pressure, reduce angina and stop gastric reflux. An inert solution injected into the brains of patients with Parkinson’s disease reduced muscle rigidity about as well as standard drugs. In a bizarre finding, sham surgery of the knee, in which patients got sedation and an incision but no actual procedure, relieved the pain of osteoarthritis better than actual arthroscopy—and produced an equal improvement in joint function, scientists reported in 2002. And last month an analysis of clinical trials of a range of antidepressants found that, except in the most severe cases, placebos lifted the black cloud as well as meds did.
