What Is a Double-Blind Study?
Definition:
A double-blind study is one in which neither the participants or the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.
For example, let's imagine that researchers are investigating the effects of a new drug.
In a double-blind study, the researchers who interact with the participants would not know who was receiving the actual drug and who was receiving a placebo.
