ASSESSING THE AWARENESS OF 4TH YEAR IN BCP BS CRIMINOLOGY STUDENTS IN THE CONDUCT OF POLYGRAPH EXAMINATION

Abstract

This study aims to examine the complex relationship between lie detector technology and legal procedures, focusing on its historical background, scientific validity, ethical considerations, and potential impact on the justice system. The admissibility of polygraph tests—commonly referred to as lie detector tests—has long been a controversial issue in legal proceedings. These tests, also known as deception detection assessments, involve asking a subject a series of questions while monitoring physiological responses such as blood pressure, heart rate, respiration, and skin conductivity. The premise is that deceptive responses trigger detectable physiological changes; however, the reliability and scientific validity of polygraph results continue to be widely debated. The study identified several limitations in polygraph training. The highest-ranked issue was the limited availability of assessment tools, followed by insufficient practical experience and, in third place, limited exposure to real-world applications and a lack of specific knowledge about polygraph procedures. To address these gaps, the top recommendation is to organize small group sessions where students can practice conducting polygraph examinations on one another, as well as invite professional examiners from law enforcement and forensic agencies to share their expertise and provide mentorship. The second-ranked solution is to offer hands-on training with polygraph equipment through simulations and practical exercises under the guidance of qualified instructors. The most strongly supported solution among respondents directly addressed the primary concern they identified. The recommendation to organize small group sessions where students practice conducting polygraph examinations on one another received the highest level of agreement, with 43 respondents (86%) in favor. Conversely, the least preferred measure was the suggestion to have students write reflective essays on their understanding of polygraph examinations, including ethical implications, limitations, and potential biases, which was supported by 35 respondents (64%).
