A placebo is an inactive substance or treatment that looks identical to the treatment being tested but has no active therapeutic ingredients. Placebos are used in clinical trials to help determine whether the treatment's effects are due to the active ingredients or to other factors such as the participant's expectations.
Randomization means participants are assigned to treatment or placebo groups by chance, like flipping a coin. Blinding means participants and sometimes researchers do not know who is receiving the treatment and who is receiving the placebo. Single-blind studies keep participants unaware, while double-blind studies keep both participants and researchers unaware of group assignments.
Placebos are used ethically when no standard treatment exists for the condition, or when the current standard treatment has limited effectiveness. Participants are always informed during the consent process that they may receive a placebo and are told the probability of receiving the treatment versus placebo.
