QuoteLying subjects sometimes claimed that the apparatus was causing them physical pain. They did this for at least one of several reasons. First, they hoped that the examiner would turn off the instrument, remove the apparatus, apologize for the pain that was caused, and then report to the investigators that the subject could not be examined because of pain sensitivity. Second, the complaint of pain provided them with an excuse for not sitting still, a behavior that prevented the examiner from obtaining a suitable recording. Third, they hoped that the examiner, when interpreting responses, would erroneously decide that their lie responses were pain responses and would thus turn in a favorable report.
Quote4.2 Standards for Rendering Polygraph Decisions
4.2.1 A member shall not render a conclusive diagnosis when the physiological records lack sufficient quality and clarity. This may include, but is not limited to, excessively distorted recordings possibly due to manipulations by the examinee, recordings with insufficient responsivity, or recordings with tracing amplitudes less than that generally accepted by the profession.
Quote4.3 Post-Examination Notification of Results
4.3.1 A member shall afford each examinee a reasonable opportunity to explain physiological reactions to relevant questions in the recordings. There are three exceptions:
4.3.1.1 When the examinee is represented by an attorney who requests that no post-examination interview be conducted, and that the results of the examination be released only to the attorney.
4.3.1.2 When the examination is being conducted by court order which stipulates that no post-examination interview is to be conducted.
4.3.1.3 Instances of operational necessity.
