THE RESULTS OF A STUDY SHOW THAT POLYGRAPH EXAMINERS ARE ABLE TO SUCCESSFULLY DIAGNOSE DECEPTION SOLELY FROM AN ANALYSIS OF POLYGRAPH RECORDS.
Abstract
THE STUDY ALSO FOUND THAT THE ACCURACY OF THE EXPERIENCED EXAMINERS WAS SIGNIFICANTLY BETTER THAN THAT OF THE INEXPERIENCED EXAMINERS. IN ACTUAL TESTING SITUATIONS THE EXAMINER PLACES THE UTMOST RELIANCE UPON RESPONSES OR LACK OF RESPONSES ON POLYGRAPH RECORDS, BUT HE IS AFFORDED THE ADDITIONAL OPPORTUNITY TO EVALUATE THE ATTITUDE OF THE SUBJECT AND TO MAKE ALLOWANCES FOR A RESENTFUL OR ANGRY ATTITUDE, A CONDITION WHICH COULD CAUSE AN ERROR IN INTERPRETATION OF POLYGRAPH RECORDS. AN OPPORTUNITY TO OBSERVE THE SUBJECT AND EVALUATE HIS ATTITUDE TOWARD THE TEST WOULD ALLOW AN EXAMINER TO DIAGNOSE TRUTH AND DECEPTION EVEN MORE RELIABLY THAN THE EXAMINERS IN THIS STUDY.
