A placebo is an inert treatment, such as a sugar pill or saline injection, that has no therapeutic effect but can produce psychological benefits due to a patient's belief in its efficacy. Placebos are important in clinical trials as they help researchers determine the actual effectiveness of new treatments by comparing them against the placebo effect. This helps to establish whether observed improvements are due to the treatment itself or the patients' expectations and psychological factors. Understanding the placebo effect also has implications for patient care and the design of effective therapies.
