Research output: Contribution to journalLetterpeer-review

Abstract

In our recent review of the current status of forensic lie detection (Iacono & Ben-Shakhar, 2019), we critiqued a novel method for estimating comparison question polygraph technique accuracy introduced by Ginton (2013). Ginton (2020) has argued that we misconstrued and misinterpreted his study. In this rejoinder, we dismiss Ginton’s (2020) critical points and maintain that his polygraph validity estimates cannot be trusted.
