Abstract
Lying or deliberate deception is a problem that can arise in criminal investigations. Research suggests that professional judgment is a far from reliable way of determining who is dissimulating. Special procedures have been developed, such as the polygraph and statement reliability analysis, but these have proved to be less than wholly accurate and typically produce an appreciable level of false positives. This paper explores how a method for the detection of malingering in clinical contexts, which can deliver highly reliable outcomes, might usefully be adapted for use with witnesses and suspects in criminal investigations.
