An Empirical Study on Dynamic Effects on Deception Detection

Abstract

A threat to accurate deception detection is the dynamic nature of deceptive behavior. Deceivers tend to adapt their communication style over time by continuously monitoring their targets for signs of suspiciousness. As a result, deceivers manage to tell lies that sound more and more like truth. Such trends imply that deception detection in later phases of an interaction would be more difficult and thus less accurate than detection in earlier phases. This paper studies dynamic effects that influence deception detection and provides empirical evidence supporting the prediction.
