The Department of Defense Polygraph Institute's Law Enforcement Pre-Employment Test includes five "control" or comparison questions in Sequence/Phase 1 and four in Sequence/Phase 2. (See Appendices E and F.)

See also Appendices A and B of the 3rd edition of The Lie Behind the Lie Detector for information regarding the Modified General Question Test (MGQT) and Zone Comparison Test (ZCT), respectively.

Hello,
Read through the "Lie Behind Lie Detector"
Can anyone tell me approximately how many control questions are in a typical polygraph exam?
