Double-blind studies control for both the placebo effect and the experimenter effect. The placebo effect occurs when a participant's belief in a treatment affects their response, even if the treatment is actually inactive. The experimenter effect occurs when the experimenter's expectations or biases influence the results of the study. Double-blind studies help to eliminate these factors by keeping both the participants and the experimenters unaware of who is receiving the treatment and who is receiving the placebo.
