Quizplus · Accepted Answer

A placebo is a treatment that is designed to be indistinguishable from the treatment being studied, but has no active ingredient or therapeutic effect. This allows researchers to control for the psychological and physiological effects of receiving a treatment, without the confounding effects of the actual drug or intervention. Placebos are often used in clinical trials to test the efficacy of new drugs or treatments.
