Your research class conducted a study on the effects of caffeine on stress, but neither the class researchers nor the study subjects were aware of who received caffeine or not until the study was finished. This research technique is called a double-blind study.

Let's say, for illustration, that scientists are looking into the effects of a novel medication. The researchers who interact with the patients in a double-blind study would be unaware of who was receiving the real medication and who was receiving a placebo.

Doctors and participants are kept in the dark about who is receiving which treatment in the double-blind trial. This last sentence is very important because it prevents researchers from unintentionally disclosing study participants' identities or slanting their opinions of the findings.

A double-blind study has a lower risk of bias than a single-blind study. Bias may occur when a researcher directly or inadvertently affects a study's findings. However, because the researcher is typically also in the dark, it is difficult to influence the study. As a result, study results are reliable, legitimate, and believable.
