Abstract: The present study aimed at investigating whether the influence of the indirect self-relevance hindsight bias, and the strategies to reduce hindsight bias in mock judges′ decision-making. A 3(debiasing strategy: hindsight group, alternative strategy and instructing strategy)× 3(indirect relevancy: irrelevancy, positive indirect relevancy and negative indirect relevancy)between-subjects design was adopted in the experiment. This experiment investigated the effect of hindsight bias with homemade questionaries of two different kinds of legal cases. The results suggested that compared with positive indirect relevancy and irrelevancy, more mock judges made legal decision to judge the existence of the fault of defendants′ actions in both legal cases, and assessed significantly higher value of severity of the fault in negative indirect relevancy. In mock judges′ decisions, the indirect self-relevance made hindsight bias to impact the admition of defendant′s faults, differently. Mean while, both stratedies were able to reduce hindsight bias in mock judges′ decision-making.
