There is little research concerning the question whether lying with gestures is possible. In this contribution, Antomo investigates this question within a traditional definition and, in a second step, within a commitment-based concept of lying. Exploiting cancellability, deniability, and the gesture-speech interaction in general, Antomo concludes that gestural lies should be possible within both accounts, but that this depends very much on the gesture type. For highly conventionalized emblematic gestures and deictic gestures that are necessary to establish reference, there is strong evidence that their content is part of the statement made and that it involves commitment. Highly ambiguous iconic gestures, that occur as co-speech gestures, on the other hand, seem to be less suitable for lying since their content is not part of the main proposition, but is contributed at the not-at-issue dimension, and, therefore, involves a lesser degree of commitment.
