Detecting Deception Across Cultures
Identifying Truth and Fiction
Project Objective: To identify cues indicating possible deception during security interviews, and explore ways to use combinations of such cues to improve the security screening process, particularly involving non-Western cultures.
Project Definition: Deception is the concealment or distortion of truth, with the purpose to mislead. It may take the form of intentional perversion of fact or omission of relevant information.
Project Importance: Although deception detection has been explored in academic settings involving people from Western cultures, we know very little about which cues may be universal across languages and cultures, and which may be language/culture-specific. Therefore, this research focuses on possible deception in interviewees from non-Western cultures.
Project Background: When different kinds of cues are used together, we improve our ability to identify deception. For example, when someone expresses praise while showing a conflicting facial expression, such cue conflict suggests deception.
Project Products:
- This research will:
- Yield recommendations for improving deception detection in non-Western cultures
- Assess the cultural dependence versus independence of known deception cues
- Suggest ways to train interviewers to identify and use deception cue combinations
Project Reports:
Project Activities:
- Verbal and non-verbal approaches to detecting deception during actual security interviews are combined:
- Linguistic analysis of transcribed interviews
- Facial movement and behavior coding
