The Verifiability Approach (VA) is a new strategy-based lie detection tool. According to the VA, when liars provide many details to make an honest impression, they prefer to provide details that they perceive as non-verifiable. As a result, liars provide fewer verifiable details than truth-tellers, and the verifiability of the account provided is used as a diagnostic indicator for veracity. Originally developed for assessing the veracity of suspect accounts in police interviews, the VA has also been examined in other settings (e.g., insurance claims). The current chapter provides an overview of the current status of the VA and subsequently discusses its further development and extension to other real-world settings. Focusing on the border security setting as a test case, relevant challenges and future research directions are demonstrated.
