Abstract
THIS PAPER IS ELIGIBLE FOR THE STUDENT PAPER AWARD. We study the problem of Bayesian persuasion under receiver distrust. In the classical Bayesian persuasion problem introduced by Kamenica and Gentzkow [AER, 2011], there are two parties, a sender Alice and a receiver Bob, who engage in a one-way interaction from sender to receiver. The sender employs a signalling strategy so as to persuade or steer the receiver toward taking a certain action(s) with respect to a random state known only to her. Both parties are rational and seek to optimize their expected utilities; however, their utilities are intimately coupled as they are functions of the random state and the receiver’s action. In this work, we initiate a systematic study of Bayesian persuasion when the receiver is distrustful of the sender. We present an if-and-only-if criterion for the existence of a signalling scheme for persuasion under distrust. Interestingly, our results unveil the existence of a regime under a so-called ‘super-distrustful’ receiver when a rational sender should seek to ‘counter-persuade’ or employ ‘counter-suasion’ to derive maximal benefit.
