A CIA analyst has published a detailed personal account exposing the flaws and inconsistencies in polygraph testing used for government security clearances. The anonymous analyst describes their experience with both initial applicant screening and regular five-year reinvestigations, revealing how the tests often produce wildly inaccurate accusations.

The analyst's journey began with extensive preparation, including reading David T. Lykken's _A Tremor in the Blood_, which they found the examiner had never heard of despite its significance in the field. During testing, they experienced physical discomfort and witnessed colleagues accused of crimes completely inconsistent with their character - from major drug use to foreign espionage. The analyst discovered that failing applicants often faced repeated testing until they passed, with one manager reportedly failing seven times before being allowed to keep his position.

Despite the agency's prohibition on discussing polygraph results, the culture of secrecy couldn't prevent widespread sharing of experiences. The analyst's account suggests systematic problems with the testing process, where examiners made accusations ranging from massive debt to computer hacking that bore no relation to the truth. Their story raises serious questions about the reliability of polygraphs as a screening tool for sensitive government positions.
