Abstract

This experiment explored the combined use of two approaches used in interrogations: The Comparable Truth Baseline (CTB) and verifiable details. Thirty-seven university students performed two sets of tasks that mimicked an undercover mission. All told the truth about the first set, while for the second half, half of the participants lied, and half told the truth. Results showed that focusing on verifiable details in CTB interviews could be an effective strategy, as only liars reported a different amount of verifiable details between the two task sets. However, there are limitations that have been discussed.
