What is the placebo effect?
The placebo effect is a beneficial health outcome resulting from a person’s anticipation that an intervention will help. How a health care provider interacts with a patient also may bring about a positive response that’s independent of any specific treatment.
What is the gold standard for testing interventions in people?
