Blinding, in the context of research and experiments, refers to a method used to prevent bias by concealing certain information from participants or researchers. This technique ensures that the expectations or beliefs of those involved do not influence the outcomes of the study. For example, in a clinical trial, participants may not know whether they are receiving a treatment or a placebo. Deception, often associated with blinding, involves intentionally misleading participants about the true purpose or nature of the study. While this can be ethically controversial, it is sometimes necessary to maintain the integrity of the research. Proper debriefing after the study is essential to inform participants about the deception used and its purpose.
