This study assessed the ability of VericatorTM, a computer-based system that evaluates credibility through speech, to detect smugglers at a mock security checkpoint. A U.S. Federal inspector questioned participants while Vericator assessed their credibility. For some N77, the inspector followed a script of questions without follow-up Scripted for the remainder N93, follow-up questions were permitted Field-like. Smuggling base rates were 34 and 35, respectively. Few smugglers were correctly identified at the checkpoint 3 of 26 and 6 of 33, respectively while many non-smugglers were correctly identified 41 of 51 and 47 of 60, respectively. Subsequent analyses produced widely disparate results but indicate that future improvements may be possible. However, the use of Vericator at security checkpoints is not supported at this time.
