An inert substance that resembles the treatment given to an experimental group is called a placebo. Placebos are often used in experiments to control for the placebo effect, which occurs when participants in a study experience a positive response simply because they believe they are receiving a treatment, even if the treatment is actually ineffective. By giving an inactive substance to a control group, researchers can compare the actual treatment group to a group that believes they received treatment, but did not receive any active intervention.
