Nocebo Effect, the opposite of the Placebo effect. The nocebo hypothesis proposes that expectations of sickness and the affective states associated with such expectations cause sickness in the expectant. The nocebo phenomenon is a little-recognized facet of culture that may be responsible for a substantial variety of pathology throughout the world. However, the extent of the phenomenon is not yet known, and evidence is piecemeal and ambiguous. While placebos are generally associated with positive outcomes, like curing an illness or getting drunk on O’Douls and having fun (if you consider that positive), the nocebo effect produces negative results, such as a cancer patient vomiting before chemotherapy starts or someone breaking out in a rash because they thought they touched poison ivy, even though it was merely an ordinary plant. One of the most talked about examples of the nocebo phenomenon was an incident published in “New Scientist.” According to the account, late one night an Alabama man, referred to as Vance, went to a cemetery and met up with a witch doctor who told Vance that he was going to die soon. Believing the witch doctor’s prediction, Vance soon fell ill and within a matter of weeks was emaciated and close to death. Vance was taken to the hospital but the medical doctors could find nothing wrong with him. Finally, Vance’s wife told the physician, Dr. Doherty, about the encounter with the witch doctor, which gave the creative physician an idea. The next day, Dr. Doherty told the couple he had tracked down the witch doctor and physically threatened him until the medicine man finally admitted he had put a lizard inside Vance that was eating him from the inside. Of course, the Doctor’s story was completely fabricated, yet he made a big show of injecting the patient with a mysterious substance and snuck in a genuine, green lizard that he pretended to extract from Vance. The next day, Vance awoke alert, hungry, and it didn’t take long before he fully recovered. Apparently, that story was corroborated by four other medical professionals, and is often cited when explaining why Voo Doo sometimes works (i.e. not because of magic, but because of the nocebo effect). altering-perspectives/2013/07/10-amazing-examples-of-mind-over-matter.html
