- A double-blind study is one in which neither the participants nor the researchers are aware of which group is getting the treatment.
- However, it also prohibits researchers from unintentionally disclosing information about the experiment.

- The participants in a double-blind study would not be aware of who was receiving the real medication and who was receiving a placebo, and neither would the researchers who contact with them.
