Quizplus · Accepted Answer

This is true. A placebo is commonly used in clinical trials as a control group to compare the effectiveness of a new drug against. Patients receiving the placebo do not receive any active ingredient but instead are led to believe that they are receiving the experimental drug. This helps researchers to determine whether the effects of the new drug are truly due to the drug itself or to other factors, such as the patients' expectations or the natural progression of their condition.
