Yes, the "E-meter" is a primitive form of lie-detector equipment: https://rationalwiki.org/wiki/Dianetics#E-Meter https://rationalwiki.org/wiki/Dianetics#E-Meter "Basically it is a simple ohmmeter that measures galvanic skin response (electronic resistance of the skin), somewhat similar to a polygraph; the user (the "preclear") provides one of the elements in a Wheatstone bridge."
