double-blind + study
The compound is compositionally built from 'double' (twofold) + 'blind' (unaware/not seeing) and combined with 'study' a B1 learner can often infer a study in which 'both sides are blind' (i.e. both participants and experimenters are unaware). However, the use of 'blind' in this technical, metaphorical research sense is somewhat specialized and may not be fully predictable without prior exposure, so it is only partially transparent.
Etymology
Double-blind study comes from a clear image: both the people taking part and the researchers are 'blind' to who gets the real treatment. Because double means two and blind means not seeing, this keeps opinions from changing the results, so the study 'prevents bias'.
