lie detector

lie detector
An instrument, sometimes called a pathometer, whose advocates claim for it that when attached to a witness, it will indicate whether he is testifying truthfully or not. People v Forte, 279 NY 204, 18 NE2d 31, 119 ALR 1198. An instrumentality used with some success to determine whether a person is telling the truth, being adapted to the registering of the blood pressure of a person being interrogated as he responds with answers to the questions propounded to him, the principle being that the blood pressure of a person changes upon the exertion of a conscious effort to tell an untruth. Anno: 34 ALR 147, s. 86 ALR 616. An instrumentality comparable to the blood pressure test but applied to the respiration, its operation being based upon the hypothesis that a person's breathing varies according to whether or not he is telling the truth. 29 Am J2d Ev § 831. See truth serum.
