The Llewellyn Encyclopedia

Term: Double Blind

DEFINITIONS

Double Blind:

In scientific research, including parapsychology, a procedure wherein neither the subject nor even the experimenter is aware of valuable key aspects of the experiment. For example, one experimenter could put a variety of photos in separate envelopes. A second experimenter would randomly choose one of the envelopes and could not have any idea of what is in the envelope. The subject would try to determine, paranormally, what is in the envelope.
