A blind-study is an experimental protocol in which knowledge of treatment assignment or study hypotheses is withheld from participants, investigators, or both, preventing expectation effects from biasing outcomes. Its parameters are: (1) the blindness level — single-blind (participants unaware), double-blind (participants and investigators unaware), or triple-blind (participants, investigators, and analysts unaware); (2) the masked information — treatment identity, group allocation, hypothesis, or data analysis plan; (3) the unmasking procedure — conducted only after data collection concludes. The method persists through protocol documentation, journal requirements, regulatory standards (FDA, ICH-GCP), and repeated application across clinical trials and behavioral experiments.

Definition
Why it is in scope
A human-made experimental methodology in which one or more participants (subjects, investigators, or both) are kept unaware of key aspects of the study — such as which treatment group they belong to or the study's hypothesis — to prevent bias from influencing outcomes. It is built to persist through protocol documentation, peer review standards, and regulatory requirements in clinical and behavioral research.
