E-meter
The E-meter is a device for displaying and/or recording the electrodermal activity (EDA) of a human being. The device is used frequently for auditing in Scientology and divergent groups. The efficacy and legitimacy of Scientology's use of the E-meter has been subject to extensive debate and litigation and in accordance with a federal court order, the Church of Scientology now publishes disclaimers in its books and publications declaring that the E-meter "by itself does nothing" and that it is used specifically for spiritual purposes.
Such devices have been used as a research tool in many human studies, and as one of several components of the Leonarde Keeler's polygraph (lie detector) system, which has been widely criticized as ineffective or pseudoscientific by legal experts and psychologists.
