摘要：National security professionals have few scientifically valid methods for detecting deception inpeople who deny being involved in illicit activities relevant to national security. Numerous detectingdeception studies have demonstrated that the Modified Cognitive Interviewing (MCI) method is onesuch method - yielding detecting deception rates (i.e. 80-85%) that are significantly above thoseachieved by chance (i.e. 50%) or by human judgments (i.e. 54-56%). To date, however, no MCIstudies have involved dilemmas of ethological interest to national security professionals. This projectbegins to address this gap in the scientific literature. In it, we compared the efficacy of MCI to that ofhuman judgments for detecting deception in scientists with expertise in biological materials. Sixty-four scientists were recruited for study; 12 met with a "terrorist" and were paid to make biologicalmaterials for illicit purposes. All 64 scientists were interviewed by investigators with lawenforcement experience about the bio-threat issue. MCI elicited speech content differences indeceptive, compared to truthful scientists. This resulted in a classification accuracy of 84.4%;Accuracies for Human Judgments (interviewers/raters) were 54% and 46%, respectively. MCIrequired little time and its efficacy suggests it is reasonable to recommend its use to national securityexperts
