Since the seminal work of Tversky & Kahneman (Science, 185:1124-1131, 1974), the anchoring effect has generated considerable interest and its effects have been extensively documented in numerous everyday situations. However, few studies have paid attention to the influence of multiple successive anchors. To analyze how the presentation of a second anchor influences legal decision-making depending on its relevance, we conducted two studies. In both experiments, participants were asked to read a text describing a trial in which two anchors (one relevant given by a prosecutor in Experiment 1 (N = 538) or a magistrate in Experiment 2 (N = 284), the other less relevant given by a baker) appeared in succession. The results show an anchoring effect when there is one anchor (relevant and less relevant). However, the effect of a relevant anchor disappears in the presence of a contradictory less relevant anchor. We discuss the psychological processes underlying this phenomenon.
自特沃斯基和卡尼曼的开创性研究（《科学》，185:1124 - 1131，1974年）以来，锚定效应引发了广泛关注，其影响在众多日常情境中都有大量记录。然而，很少有研究关注多个连续锚定的影响。为了分析第二个锚定的呈现如何根据其相关性影响法律决策，我们进行了两项研究。在两个实验中，参与者都被要求阅读一篇描述审判的文本，其中两个锚定（在实验1（N = 538）中由检察官给出的一个相关锚定，或在实验2（N = 284）中由治安法官给出的一个相关锚定，另一个不太相关的锚定由面包师给出）相继出现。结果表明，当只有一个锚定（相关和不太相关）时存在锚定效应。然而，在存在矛盾的不太相关锚定的情况下，相关锚定的效应消失了。我们讨论了这一现象背后的心理过程。
