Effects of Examiner's and Examinee's Race on Psychophysiological Detection of Deception Outcome Accuracy.
Abstract
This study was designed to assess how the race of the examinee and/or the race of the examiner affected the accuracies of Modified General Question Technique (MGQT) and Zone Comparison Test (ZCT) psychophysiological detection of deception (PDD) examinations. The study utilized 213 military (50 African-American, 108 Caucasian, 52 Hispanic, and 3 other), and 168 civilian (45 African-American, 110 Caucasian, and 10 Hispanic, and 3 other) examinees. Two hundred and thirty-two examinees were male and 147 examinees were female. The examiners were three African-American, three Hispanic, and seven Caucasian student examiners from the Department of Defense Polygraph Institute (DoDPI) Basic Polygraph Examiners Training Course (91-1). The students participated in the study during their 7th, 8th, 10th, and 11th weeks of instruction. Students utilized field polygraph instruments. A variety of scenarios (rape, murder, robbery) were used to program examinees to be guilty. Analyses of the data included an assessment of the effect of the race of the examinee on the accuracies of the examinations, the effect of the race of the examiner on the accuracies of the examinations, and the effect of the interaction of the race of the examinee and the race of the examiner on the accuracies of the examinations. The accuracies of the examinations were not different based on the race of the examinee, the race of the examiner, nor the interaction of the races of the examinee and examiner.
