Implacebole?

In a famous 1955 monograph in the Journal of the American Medical Association, Henry Beecher coined the term "powerful placebo." He used it to describe the miraculous improvement he said was seen in patients who thought they were getting medicine but really weren't. Beecher went so far as to say that this placebo effect accounted for precisely 35.2 percent of a treatment's results. And so he popularized the notion that patients could spontaneously heal—not only from psychological distress, but from physical disease—if they simply believed they were getting treatment.
Beecher's paper is highly suspect. Half the studies he cited were his own, and his math was, frankly, misleading. Ted Kaptchuk, an associate professor at Harvard Medical School and former FDA expert panelist, dismisses the paper as a "polemical ploy," and other researchers have derided Beecher as "statistically naïve to the extreme." And yet Beecher's paper and the notion of a powerful placebo effect have escaped widespread scrutiny. For decades, mainstream medicine has uncritically promoted faith in the placebo effect leaving behind reality-based science in the process(more from slate)
