Double Blind In the context of a clinical trial, double-blind means that neither the patients nor the researchers know who is getting a placebo and who is getting the treatment. Because patients don't know what they're getting, their belief about what will happen doesn't taint the results.
The double blind method is an important part of the scientific method, used to prevent research outcomes from being 'influenced' by the placebo effect or observer bias. Blinded research is an important tool in many fields of research, from medicine, to psychology and the social sciences, to forensics. Blinding is a basic tool to prevent conscious and unconscious bias in research.
