Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.

How do you conduct a double blind experiment?

A double blind experiment requires that both researchers and test subjects are unaware of who is receiving the treatment and who is receiving the placebo. If only one group is unaware, it is a single blind experiment. If both groups are aware, the experiment is not blinded.

By keeping participants and researchers unaware of which condition the patient is assigned to researchers can determine if the placebo effect is at work. these procedures are irreversible.

What is the advantage of a double-blind experimental design quizlet?

Double-blind studies not only protect against participant bias but also mitigate the effects of experimenter bias.
