| Abstract: | This essay continues a debate about the relative scientific merits of the Park‐Levine Model (PLM) and Interpersonal Deception Theory (IDT) with regard to accuracy in deception detection. Key points of disagreement include (a) the degree to which message recipients are sensitive to sender veracity and (b) the extent to which interactivity moderates the veracity and base‐rate effects specified by PLM. According to PLM, people are truth‐biased, truth‐bias makes people insensitive to deception, and as a consequence, base rates affect accuracy regardless of interactivity. IDT, in direct contrast, holds that people are sensitive to the veracity of other's communication and that interactivity is a key moderator. Consistent with PLM, data repeatedly show that people are insensitive to other's veracity and that this insensitivity is general across media affordances including interactivity. This rejoinder uses Burgoon's (2015) own interactive data to demonstrate the empirical superiority of PLM over IDT. |
