The power of Placebo
"Doctors in one study successfully eliminated warts by painting them with a brightly colored, inert dye and promising patients the warts would be gone when the color wore off. In a study of asthmatics, researchers found that they could produce dilation of the airways by simply telling people they were inhaling a bronchiodilator, even when they weren't. Patients suffering pain after wisdom-tooth extraction got just as much relief from a fake application of ultrasound as from a real one, so long as both patient and therapist thought the machine was on. Fifty-two percent of the colitis patients treated with placebo in 11 different trials reported feeling better -- and 50 percent of the inflamed intestines actually looked better when assessed with a sigmoidoscope ("The Placebo Prescription" by Margaret Talbot, New York Times Magazine, January 9, 2000) "
A crotchety old man was successfully convinced that his hearing and sound system improved after receiving a 30 second phone call. ("Baiting Norm" by Pauly, Audiogon Forum, August 31, 2007)
