Bayesian Persuasion describes the phenomena where a sender of information intends to sway a receiver to take his/her desired action by choosing what information the receiver can access. This occurs in many economic and social settings, for example a prosecutor persuading a judge to convict a suspect or a politician persuading voters that he/she is the best candidate and therefore deserve their vote. While Bayesian Persuasion has been studied in theory, there has been little real world study of its implications. Given the prevalence and complexity of the use of Bayesian Persuasion, it is important to investigate whether the sender can find the best information to induce his/her desired action with the maximum frequency, and if not, what makes it so difficult. This proposed research will use a series of experiments to study the Bayesian Persuasion phenomenon. Such an investigation helps to build an understanding about several situations that involve Bayesian Persuasion, such as how a prosecutor chooses to investigate a criminal case and how politicians design their promotion campaigns. The results of this research will improve the efficiency of advertising, public policy campaigns, and general policy discussions.This project uses a series of lab experiments to test the theory of Bayesian Persuasion. The researchers will design laboratory experiments where the process of Bayesian Persuasion is maximally simplified for the sender. The experimental design will eliminate the need for the sender to perform any Bayesian updating. Because people are in general not capable of Bayesian updating, such simplification allows researchers to focus solely on the key parts of the Bayesian Persuasion reasoning. The experiment will then introduce some realistic difficulties to the problem to check the robustness of the results. The research goal is to shed light on the empirical soundness of the theory of Bayesian Persuasion---to what extent is the theoretical prediction correct and how should economists revise their understanding of the theory if necessary. The results of this research project will not only (in)validate the theory of Bayesian Persuasion but also show its practical application. This will improve discourse on important issues in business, public policy, and governance generally.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

贝叶斯劝说描述了这样一种现象，即信息发送者打算通过选择接收者可以访问的信息来影响接收者采取他/她想要的行动。这在许多经济和社会环境中都会发生，例如检察官说服法官判定嫌疑人有罪，或政客说服选民他/她是最佳候选人，因此值得他们投票。尽管人们在理论上对贝叶斯劝说进行了研究，但很少有人在现实世界中研究它的含义。鉴于贝叶斯劝说使用的普遍性和复杂性，重要的是调查发送者是否能找到最佳信息，以最大频率诱导他/她想要的行动，如果不能，是什么使其如此困难。这项拟议的研究将使用一系列实验来研究贝叶斯说服现象。这样的调查有助于建立对涉及贝叶斯劝说的几种情况的理解，例如检察官如何选择调查刑事案件，政客们如何设计他们的宣传活动。这项研究的结果将提高广告、公共政策活动和一般政策讨论的效率。本项目使用一系列实验室实验来检验贝叶斯说服理论。研究人员将设计实验室实验，为发送者最大限度地简化贝叶斯劝说过程。实验设计将消除发送者执行任何贝叶斯更新的需要。由于人们通常不能进行贝叶斯更新，这样的简化使研究人员能够只关注贝叶斯说服推理的关键部分。然后，实验将为问题引入一些现实困难，以检查结果的稳健性。研究的目标是阐明贝叶斯说服理论的经验合理性-理论预测在多大程度上是正确的，以及经济学家应该如何在必要时修改他们对该理论的理解。本课题的研究结果不仅验证了贝叶斯劝说理论的正确性，而且显示了其实际应用价值。这将改善对商业、公共政策和治理中的重要问题的讨论。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
