A former CIA analyst shared her detailed experience undergoing polygraph tests as part of the agency's applicant screening process. During her time at the CIA and subsequent work as a contractor for organizations like the National Reconnaissance Office (NRO), FBI, and Defense Intelligence Agency (DIA), she faced rigorous testing to assess honesty and suitability. Her journey began with reading *A Tremor in the Blood* by David T. Lykken, which introduced her to polygraph techniques such as control versus relevant questions and countermeasures like stress-inducing tactics. Despite knowing these methods, she chose not to use them, opting instead to answer truthfully, believing honesty was key.
The analyst described her first polygraph experience at a nondescript building in Vienna, Virginia. After signing a consent form, she was wired up for the test, which involved answering questions about past behavior, including whether she had ever lied to her boss or made false statements on applications. Though she answered truthfully, she struggled with physical discomfort from the testing equipment and the pressure of maintaining stillness. Midway through the exam, the evaluator left to show charts to a supervisor, prolonging her anxiety. She ultimately failed the test, leading to uncertainty about her future in intelligence work.
Reflecting on her experience, the analyst highlighted the emotional toll of the process. She felt judged by the examiner's probing questions and struggled with self-doubt after failing the polygraph, questioning her integrity. Despite this, she emphasized the importance of honesty in security roles, even when it comes at personal risk.
