Discriminating Deceptive From Truthful Statements Using the Verifiability Approach
Bruno Verschuère, Glynis Bogaard, Ewout H. Meijer · Applied police briefings : · 2024
This brief is based on the following published work:Verschuere, B., Bogaard, G., & Meijer, E. (2020). Discriminating deceptive from truthful statements using the verifiability approach: A meta-analysis. Applied Cognitive Psychology, 35(2), 374–384. https://doi.org/10.1002/acp.3775 When considering suspect statements, truthful statements contain more verifiable details compared to deceptive statements, supporting a core prediction of the Verifiability Approach (VA) to lie detection. However, this difference of verifiable details between truthful and deceptive statements is not always found. For example, the difference emerges for alibi statements, but not for other types of statements, such as statements related to insurance claims. While the VA appears to be a useful tool for detecting lying in laboratory-based studies, the effectiveness of the VA in real-world policing contexts remains unknown.
