Who's the deceiver? Identifying deceptive intentions in communication
研究在沟通游戏中识别欺骗意图的新方法，通过实验发现仅依赖传统策略性博弈和信念问卷可能误判大量发送者的真实意图，新方法能更好区分实际欺骗者与悲观诚实者。
Recognizing people's deceptive intentions when communicating is crucial to detect statements that may drive us to unintended harmful decisions. This paper studies individuals' intentions in games where players can tell the truth with deceiving purposes. In a preregistered experiment, we combine a sender-receiver game with possible strategic considerations and the associated belief elicitation questionnaire, with a sender-receiver game with no room for strategic considerations. We propose a new method that improves the identification of senders' intentions to deceive. Our findings reveal that relying solely on the strategic sender-receiver game and the elicited beliefs, as previously proposed in the literature, can lead to misinterpreting the actual intentions of a substantial proportion of senders. In particular, our new method helps discern actual deceivers from pessimistic truth-tellers and identifies senders who try to excuse their previous deceiving message. All in all, our method identifies more senders with deceptive intentions compared to previous methods.
