The placebo effect occurs when a person experiences a positive outcome (such as improvement in a medical condition) due to their belief in the effectiveness of a treatment, rather than the treatment itself having any therapeutic effect. This is often observed in clinical trials where a placebo (an inert substance) is given to a control group, and improvements are noted based on the individuals' beliefs that they are receiving an active treatment.
