Lissa Rankin checks out how the placebo effect has spiritual and scientific ramifications over us in this TEDtalk. She probes deeply into how our thoughts can powerfully affect our physiology. Lisa explores the possibility that we in fact get well if we believe we can. The Placebo effect is a valid proof that the body has an innate self-repair system.


3,500 people diagnosed with deadly diseases like HIV, cancer, heart diseases, etc., took part in a study to test the placebo effect. Everyone’s illness vanished without treatment!

Lisa refers to a case of a Mr. Wright who was diagnosed with cancer and was given drugs he believed could cure him. Within merely days of taking the drugs, his tumors had shrunk to half their size. A report was released after two months regarding the drug, that said it didn’t work so well and Mr. Wright’s cancer was back.

His crafty doctor assured Mr. Wright that he had procured a higher quality version of the same drug and injected him with distilled water. His tumors disappeared again because he trusted they could. For another two months Mr. Wright was fine until the American Medical Association published a nationwide study that proved the drug was of little value. After two days Mr. Wright died.


Lisa recounted other innumerable times when people in actual fact healed themselves with measurable proof on this TEDtalk. They heal their ulcers, grow back hair, shrink tumors and reduce all signs of illness! The mind launches the healing and the body responds.
