Judicial Reform Charging Station - JUDICIAL PRO X: Oh God, Please Tell Me If This Person Is Lying!
Last edited: 2026-07-27
I wonder if you have ever had the strong desire to know whether someone was lying. In daily life, people might judge whether someone is lying through their gaze, facial expressions, body language, or whether their statements are contradictory. The same situation exists in judicial cases.
In judicial proceedings, there is a method of forensic evaluation called "lie detection" (polygraph testing), which claims to monitor a subject's various physiological responses through instruments to determine whether the subject is lying. Doesn't this sound impressive? Lie detection was once seen as the hope for ending wrongful convictions because it supposedly cannot be wrong. However, as successive wrongful conviction cases involving polygraphs have come to light, questions began to arise: How is a polygraph test properly conducted? What makes its interpretation and application reasonable?
This event invites a polygraph examiner to explain, from the perspective of an examiner, the principles of lie detection, current methods available, the possibilities and limitations of different methods, and how to identify procedural issues in lie-detection cases. We will also explore what makes judicial practitioners' interpretations and uses of polygraph results reasonable or unreasonable from an examiner's perspective.
※ Polygraph equipment will be available on-site, offering a chance to experience a lie detection test firsthand.
