The Selective Disclosure of Evidence: An Experiment
实验研究沟通中的选择性披露：发送者从证据池挑选证据披露而非全部隐瞒。发现选择性披露比隐瞒更普遍、对接收者扭曲更大，且部分发送者厌恶欺骗会过度沟通，接收者则过于乐观。对研究沟通与信息披露的实验者有用。
Abstract We conduct an experimental analysis of selective disclosure in communication. In the model, an informed sender aims to influence a receiver by disclosing verifiable evidence that is selected from a larger pool of available evidence. Our experimental design leverages this model’s rich comparative statics, allowing us to systematically quantify the effects of selection relative to concealment. Our findings confirm the key qualitative predictions of the theory, suggesting that selection, rather than concealment, is often the dominant distortion in communication. We also identify deviations from the theory: Some senders are “deception averse” and overcommunicate relative to predictions; receivers respond too optimistically to both concealed and selected evidence, with errors of similar magnitude. Yet selection generates greater overall distortion in receiver behaviour because it is far more prevalent than concealment.
