Hide or Surprise? Persuasion without Common-Support Priors
نویسنده
چکیده
Often persuaders have a richer understanding of the world than their audience. This paper models such situations by letting persuader and audience have prior beliefs with different supports. This asymmetry adds unexplored aspects to the persuasion problem: Persuaders can hide their superior knowledge or surprise their audience with unexpected information; After surprises Bayes’ rule cannot describe how the audience responds. The paper examines persuaders’ incentives to hide and surprise and their resulting communication strategies. It also shows under which conditions they surprise their audience as well as hide some information, and which information they hide.

متن کاملBeliefs and disagreement in OrganizatiOns
Managers often face a choice between authority and persuasion. In particular, since a firm’s formal and relational contracts and its culture and norms are quite rigid in the short term, a manager who needs to prevent an employee from undertaking the wrong action has the choice between either trying to persuade this employee or relying on interpersonal authority.
