Using a standard cheating game, we investigate whether the request to sign a no-cheating declaration affects truth-telling. Our design varies the content of a no-cheating declaration (reference to ethical behavior vs. reference to possible sanctions) and the type of experiment (online vs. offline). Irrespective of the declaration's content, commitment requests do not affect truth-telling, neither in the laboratory nor online. The inefficacy of commitment requests appears robust across different samples and does not depend on psychological measures of reactance.

承诺要求不影响实验室和在线实验的真实性

使用标准作弊游戏，我们调查要求签署不作弊声明是否会影响说真话。我们的设计改变了不作弊声明的内容（参考道德行为与参考可能的制裁）和实验类型（在线与离线）。无论声明的内容如何，​​承诺请求都不会影响说真话，无论是在实验室还是在网上。承诺请求的无效性在不同的样本中显得很明显，并且不依赖于心理反应的测量。
