| nocebo effect (We have long known that expectations of a malady can be as dangerous as a virus. In the same way that voodoo shamans could harm their victims through the power of suggestion, priming someone to think they are ill can often produce the actual symptoms of a disease. Vomiting, dizziness, headaches, and even death, could be triggered through belief alone. It's called the "nocebo effect". BBC Alexander Demidov) | |||
