Both the experimenter and participants are unaware of the assignment

Detailed explanation-1: -In a double-blind study, both participants and experimenters are blinded. In a triple-blind study, the assignment is hidden not only from participants and experimenters, but also from the researchers analyzing the data.
Detailed explanation-2: -As mentioned previously, double-blind indicates that the participants and the experimenters are unaware of who is receiving the real treatment. 1 What exactly do we mean by ‘treatment’?
Detailed explanation-3: -A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over.
Detailed explanation-4: -Therefore, both research participants and researchers are blind to this information. Double-blind studies help in reducing the biases like the placebo effect, experimenter bias, and experimenter expectancy effect that hinder the results and conclusions of the study.
Detailed explanation-5: -In a double-blind study, both the researchers and the participants are blind to group assignments. Why would a researcher want to run a study where no one knows who is in which group? Because by doing so, we can control for both experimenter and participant expectations.
