Section III, "Pre-Test Paperwork," Dean discusses the pre-test questionnaires that some agencies require be filled out prior to a polygraph interrogation. One interesting tip she provides is this: Quote:
Section IV, "Interview" discusses the pre-test interview phase of the polygraph interrogation. Dean warns against attempts to ingratiate oneself with the polygrapher, or to "try to use humor to get through the test." She urges the reader to be sure to accurately complete their "Personal History Statement," noting, "It has been my experience that 90% of applicant's [sic] PHS's [sic] or other background forms contain errors or omissions." Subsections to Section IV discuss how to respond to questions, emphasizing the importance of providing specific rather than general answers, for example: Quote:
In a subsection on semantics, Dean advises: Quote:
Here, Dean fails to warn readers about the dangers of "spilling one's guts" to one's polygrapher during the pre-test interview. As noted in The Lie Behind the Lie Detector, admissions made during the pre-test phase may be spun out of all proportion if the polygrapher later thinks he/she sees signs of deception in the charts. Section 22 [sic], "The Test" notes in subsection 1: Quote:
Dean has just described a commonly used "control" question. (She is incorrect, however, in stating that the examiner "must" ask a question about theft from an employer. Other "control" questions may be used instead.) Moreover, Dean fails to warn the reader that his/her answer to this question is expected to be untrue, even after any admissions have been made. In subsection C., "Nervousness," Dean writes: Quote:
Dean might honestly believe the above nonsense, but she is dead wrong. There is no such thing as a "lie reaction" which can be distinguished from a "nervous reaction." If your heart races, your palmar perspiration rate increases, or your breathing becomes erratic after you truthfully but nervously answer an accusatory relevant question, you run a strong risk of becoming a false positive. Dean's next suggestion in this subsection is quite right, however: Quote:
As noted in The Lie Behind the Lie Detector, polygraphers tend to interpret slow, deep breathing as an attempt at polygraph countermeasures. continued in following post... |
