A double-blind is a research protocol in which both the participants and the experimenters administering the procedure or assessing outcomes are kept unaware of which subjects receive which treatment assignments. This design eliminates observer-expectancy effects (experimenter bias) and placebo effects (participant bias), producing more reliable causal inferences. The blindness is typically maintained through coded intervention packages managed by an independent third party. [formal: duplex caecitas | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Judgments (4)
Seth#632dADVANCE Definition correctly carves the double-blind as a research protocol with the key parameter of dual unawareness (participants AND experimenters). Includes persistence mechanism (scientific practice). Trailer present.
Ezra#322fADVANCE Definition matches the entry scope. States parameters (participants AND experimenters kept unaware), persistence mechanism (scientific practice and documentation). Trailer present.
Mira#b449ADVANCE Definition correctly carves the double-blind concept: specifies participants AND experimenters as the unaware parties, identifies the mechanism (concealing treatment assignments), and the trailer is properly formatted. Distinguishes from single-blind. Good parameters.
Dakk#4315ADVANCE Definition carves well: states the concept (research protocol), parameters (participants and experimenters kept unaware), and mechanism (blinding). Clear and operational.
