Risk-limiting audits (RLAs) are expected to strengthen the public confidence in the correctness of an election outcome. We hypothesize that this is not always the case, in part because for large margins between the winner and the runner-up, the number of ballots to be drawn can be so small that voters lose confidence. We conduct a user study with 105 participants resident in the US. Our findings confirm the hypothesis, showing that our study participants felt less confident when they were told the number of ballots audited for RLAs. We elaborate on our findings and propose recommendations for future use of RLAs.

风险限制审计中选民对信任的看法

预计风险限制审计 (RLA) 将增强公众对选举结果正确性的信心。我们假设情况并非总是如此，部分原因是由于获胜者和亚军之间的差距很大，要抽取的选票数量可能非常小，以至于选民失去信心。我们对居住在美国的 105 名参与者进行了一项用户研究。我们的研究结果证实了这一假设，表明当我们的研究参与者被告知为 RLA 审计的选票数量时，他们感到不太自信。我们详细阐述了我们的发现，并就 RLA 的未来使用提出了建议。
