Despite the importance and neutrality of constitutional rights, empirical research suggests that ideological inclinations unduly affect their assessment and application. In this study, we conducted two experiments in order to investigate the nature of the ideological bias in a constitutionally relevant decision (right-to-demonstration), and how to mitigate it. We find that ideological bias is driven by in-group favoritism. In addition, we find that prior commitment, through a signed declaration, to be impartial or to prioritize constitutional rights encourages participants not to disfavor out-groups. On the other hand, we do not find evidence that using a temporary blinding procedure mitigates the ideological bias.

宪法判断中的意识形态偏见：实验分析和潜在解决方案

尽管宪法权利的重要性和中立性，实证研究表明，意识形态倾向过度影响了它们的评估和应用。在这项研究中，我们进行了两项实验，以调查与宪法相关的决定（示威权）中意识形态偏见的性质，以及如何减轻它。我们发现意识形态偏见是由群体内偏袒驱动的。此外，我们发现，通过签署声明事先承诺不偏不倚或优先考虑宪法权利会鼓励参与者不偏袒外部群体。另一方面，我们没有发现证据表明使用临时盲法可以减轻意识形态偏见。
