which the sender and receiver make psychological predictions about the other's behavior based on specific prior knowledge; this conceptual ambiguity limited IDT's explanatory power. However, Buller and Burgoon responded to this type of critique, saying the theory "was not meant to advance a single explanatory mechanism but instead to fit a broad communicative perspective on the phenomenon and to include multiple causal mechanisms that fit a general interpersonal communication account of the process." Park and Levine (2015) provide additional commentary questioning IDT stating that “because both interactive and noninteractive experiments lead to the same conclusions about truth-bias and accuracy regardless of interactivity, interactivity is not the all-important consideration as IDT claims.” In IDT, a crucial emphasis is placed in the aspect of interactivity to determine deception detection accuracy. However, Park and Levine do not see an empirical basis for this foundational claim of IDT.

Experiment Buller and Burgoon asked participants to put themselves in the following situation: "You've been dating Pat for nearly three years and feel quite close in your relationship. Since Pat goes to a different school upstate, the two of you have agreed to date other people. Nevertheless, Pat is quite jealous and possessive. During the school year you see Pat only occasionally, but you call each other every Sunday and talk for over an hour. On Friday one of your friends invites you to a party on Saturday night, but the party is 'couples only' so you need a date. There's no way that Pat could come down for the weekend. You decide to ask someone from your class who you've been attracted to so that you can go to the party. The two of you go and have a great time. On Sunday afternoon, there's a knock on your door and it's Pat. Pat walks in and says, 'Decided to come down and surprise you, tried calling you all last night, but you weren't around. What were you doing? The researchers listed three possible responses:
