The bogus pipeline as lie detector: two validity studies.

Abstract

The validity of the bogus pipeline procedure for eliciting truthful responses from subjects in social psychological experiments was tested in two studies. Subjects were illegitimately informed about how to perform well on an experimental test, were tested, and then were asked whether they had possessed this prior information. As compared to subjects responding to pencil-and-paper questions or face-to-face questionning by the experimenter, those in a bogus pipeline condition confessed more often.
