Morphology
double-blind + procedure
The phrase combines familiar words: 'double' (twofold) + 'blind' (unaware) + 'procedure' (ordered steps), so a B1 learner who knows the constituents can reasonably infer it refers to a process in which two parties are kept unaware. However, the precise experimental sense (specifically which parties are blind and why—participants vs. experimenters, placebo/treatment mechanics) is domain-specific and not fully predictable from the parts alone.
Etymology
Double-blind procedure comes from the image of double blind: two groups are blind, kept 'in the dark' about who gets the real medicine and who gets a fake one. So it means an experiment where neither the people taking part nor the researchers know who has the treatment, which helps keep the results fair.
