Truth, Deceit, and Neuroimaging: Can Functional Magnetic Resonance Imaging Serve as a Technology-Based Method of Lie Detection?

摘要

The United States legal system places great emphasis on juries, tasking them with determining the credibility of witnesses that testify in court. However, extensive research has found that humans are generally good at lying and quite bad at detecting the lies of others. Studies have found that in face-to-face meetings, the average individual is able to detect deception at a rate only slightly better than 50%, the same rate that would be expected by chance. This has led courts to search for a more objective, technology-based method of lie detection, which could potentially improve on humans' natural ability (or inability) to detect deception.
