Hot–cold reciprocation gaps
摘要
We study whether and why the mode of decision-making affects reciprocation in a binary trust game, using three preregistered online experiments. Trustees – some of whom were exogenously induced to be surprised by trust – either decided whether to reciprocate after observing their partner’s choice ( hot mode) or committed in advance to a contingent response plan ( cold mode). In our Baseline experiment, once participants gained experience, reciprocation became more likely under hot than under cold decision-making, especially when trust was unlikely – consistent with a model in which positive surprise at being trusted increases the utility of reciprocating. Results from the other two experiments show that surprise promotes reciprocation only when trust reflects an intentional choice by the trustor and when cognitive load in the decision environment is not too high.
中文摘要
我们通过三项预注册的在线实验，研究决策模式是否以及为何会影响二元信任博弈中的回馈行为。受托人——其中部分人被外生地诱导对信任感到意外——要么在观察到搭档的选择后决定是否回馈（热模式），要么事先承诺一项 contingent 回应计划（冷模式）。在我们的基线实验中，一旦参与者获得经验，热模式下的回馈比冷模式下更可能发生，尤其是在信任不太可能时——这与一个模型一致，即被信任所带来的正向意外会增加回馈的效用。另外两项实验的结果表明，只有当信任反映信任者的有意选择，且决策环境中的认知负荷不太高时，意外才会促进回馈。
