Abstract
Lie detection research has reached a stage where theory building is possible. We believe practitioners should contribute to theory as it is being developed. With this in mind, we briefly review contemporary theories - namely the Adaptive Lie Detector theory and Truth Default Theory - and consider the practical implications for reducing bias and increasing accuracy when making lie-truth judgements. There are practical issues that theory has yet to address, which are briefly considered. This article intends to spotlight the on-going academic work in lie detection in hope that practitioners will feedback to researchers about how theory may relate to their work, and in turn help steer the direction of future research.

Lie detection research has reached a stage where theory building is possible
Theorising in the area is still nascent, and so while we consider the implications of theory for practitioners, we would encourage caution in adopting any suggestions here until further research has more rigorously tested the theories. This forward-looking article aims to spotlight the academic work on-going in the area with the hope that practitioners will feed back to researchers about how theoretical work may relate to their practice, and to work with researchers to help steer the direction of future research
Truth Default Theory (TDT) does not offer instruction on how to incorporate this into a questioning script, it does argue that people can be trained in this approach, and that it results in higher rates of accuracy when compared to passive lie detection (Blair et al, 2010; Levine, Clare, Green, Serota & Park, 2014; see Levine & McCornack, 2001, for evidence that active questioning can increase the bias to believe rather than increase accuracy)
