Australian criminal justice student’s beliefs about lie detection methods

Abstract

Abstract Criminal justice practitioners’ use of erroneous lie-detection methods contributes to inaccurate convictions and research indicates some Queensland police are using fallible methods. A recent study showed that Queensland universities primarily ignore the topic of lie detection. Thus, criminal justice students entering Queensland universities with fallacious lie detection beliefs are unlikely to have them corrected. It was unknown if Australian criminal justice students hold inaccurate lie detection beliefs. Therefore, this mixed-methods study investigated undergraduate students’ beliefs about lie detection methods, many of whom were enrolled in criminal justice-focused degrees at a Queensland-based university. Sixty undergraduate students responded to open and closed-ended questions regarding their intentions to work in the criminal justice system, their opinion on their lie detection ability, methods used to determine deception, and thoughts about cross-cultural lie detection. The findings revealed a prevalence of false beliefs about cues to deception indicating educational needs for Australian criminal justice-career-focused students.
