E-meter
The E-Meter (also electropsychometer and Hubbard Electrometer) is an electronic device used in Scientology that allegedly "registers emotional reactions".[1] After claims by L. Ron Hubbard that the procedures of auditing, which used the E-Meter, could help heal diseases, the E-Meter became the subject of litigation.[2][3][4] Since then, the Church of Scientology publishes disclaimers declaring that the E-Meter "by itself does nothing", is incapable of improving health, and is used solely for spiritual purposes.[5]
