When Messages With Persuasive Motives Are AI ‐Enhanced: An Examination of Receivers' Evaluations of the Sender

ABSTRACT The rapid development of easily accessible AI‐based tools makes it possible for senders to enhance the text in their messages. Yet, how receivers react to such messages, particularly when the use of AI is not disclosed, is far from clear. This study examines the effects of AI‐enhanced text on the receiver's reactions to the individual sender. The results from three experiments, in which messages from senders with persuasive intent were manipulated (no AI enhancement vs. AI enhancement), show that receivers reacted with reduced evaluations of the sender when the text was AI‐enhanced. Moreover, in each experiment, this effect was mediated by beliefs about AI use and trust in the sender. The results imply that senders (who want to be positively evaluated) should avoid enhancing their texts by means that boost receivers' beliefs about the involvement of AI tools.
