Former Scientologist Chris Shelton spent thousands of hours using the e-meter to “audit” fellow members of the Church—but what does the device actually measure, and why do Scientologists trust it as an infallible guide to the truth? Chris takes us inside a typical auditing session, explaining the personal questions auditors ask, the needle movements they watch for, and what they believe those reactions reveal. We compare the e-meter with the polygraph, explore how relentless questioning can produce false memories and confessions, and examine how auditors can sincerely believe they are helping even when their methods become coercive or abusive. If you’re interested in Scientology, interrogation, or behavior reading, this is a fascinating look at how a simple machine can acquire enormous power through belief.
