In a double-blind research procedure, say, for a pill designed to combat depression (which, for convenience, I'll call Pill A), can be very beneficial to the research adjudicators. By both the research administrators and participants not knowing which pill is which (Pill A or a placebo), it guarantees that there are no human errors in the area regarding administrators' and participants' attitudes, mannerisms, or behavior towards each other or their perception as to whether the pill that has just been administered to the participant is the real Pill A or just a placebo.
It's essentially security through anonymity, as the results can't be skewed by the research adjudicators or participants. The placebo is just an added layer of anonymity in the sense of the hypothetical Pill A mentioned above. It could be the real Pill A, so the real Pill A, or it could be sugar. The point is simply that it removes human error in a key area of the study.
