double-blind studies

A double-blind study is a research method used to eliminate bias in clinical trials or experiments. In this setup, neither the participants nor the researchers know who receives the treatment or a placebo. This helps ensure that expectations do not influence the outcomes. For instance, if a new medication is being tested, both the doctors and the patients are unaware of who is receiving the drug and who is getting a sugar pill. By keeping this information hidden, the study aims to produce more reliable and objective results, leading to better conclusions about the treatment's effectiveness.
