摘要：The United States legal system places great emphasis on juries,tasking them with determining the credibility of witnesses that testifyin court. However, extensive research has found that humans are generallygood at lying and quite bad at detecting the lies of others.1 Studieshave found that in face-to-face meetings, the average individual isable to detect deception at a rate only slightly better than 50%, thesame rate that would be expected by chance.2 This has led courts tosearch for a more objective, technology-based method of lie detection,which could potentially improve on humans’ natural ability (or inability)to detect deception.3
