Cross-cultural deception detection: Measuring perceptions of different cultural cues to deceit and Australian security officials’ ability to detect cross-cultural deceit, in interpersonal interactions.

This study investigates the effectiveness of Australian Federal Police (AFP) officers in detecting deception across cultural boundaries, focusing specifically on individuals from Australian and Asian backgrounds.

Using a replica of the Global Deception Research Team’s (GDRT) 2006 study, the research compares contemporary beliefs about deceptive behaviours to past findings and further assesses practical deception detection abilities via a video-based task involving Australian and cross-cultural storytellers.

Results from surveys and video assessments reveal persistent reliance on stereotypical cues such as gaze aversion and body movement, though belief in such cues has generally diminished since 2006.

The AFP were not any better than non-AFP respondents at detecting deceit after reviewing several different video interviews.

Overall, the AFP were better at detecting deception from Australian rather than overseas subjects and demonstrated a lie bias when assessing credibility across both groups.

These findings underscore the complexity of cross-cultural deception detection, highlight the limitations of stereotypical indicators, and suggest a need for more nuanced, culturally informed training approaches for law enforcement and security professionals.
