<h3>What is double-blind research study?</h3>
- 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.
- This type of study is particularly helpful in avoiding biased reports that are likely the result of placebo effects.
- Imagine, for instance, that researchers are looking into the effects of a novel medication.
