An experimental study that is done in such a way that both the primary researcher and the subjects (patients) do not know which subjects are receiving he placebo or the actual treatment.
The beneficial effect produced by a placebo that cannot be attributed to the properties of the placebo itself and must therefore be due to the patient's belief in the treatment.
