ESP forced-choice test

in parapsychology experiments, a technique in which a participant’s “calls,” or guesses, are restricted to a predetermined set of targets, as with Zener cards. The main advantages of this procedure are that the success or failure of the participants’ calls should be (a) unambiguous and (b) statistically measurable, enabling them to be compared with chance expectations.
