Abstract

For unfamiliar faces, deciding whether two photographs depict the same person or not can be difficult. One way to substantially improve accuracy is to defer to the 'wisdom of crowds' by aggregating responses across multiple individuals. However, there are several methods available for doing this. Here, we investigated performance in three tests of unfamiliar face matching. In all cases, we found that going with the option chosen by the majority of people provided the best approach. No benefit was found by weighting an option's popularity using average confidence, while choosing the 'surprisingly popular' option resulted in a sizeable decrease in accuracy. Therefore, rather than incorporating metacognitive judgements, we endorse a simple majority vote for this particular task.

大多数人的脸部匹配:从人群中获得最好的。
对于不熟悉的面孔,判断两张照片是否描绘的是同一个人可能会很困难。有效提高准确性的一种方法是通过汇总多个个体的反应来遵从“群体智慧”。然而,有几种方法可以做到这一点。在这里,我们研究了在三个不熟悉面孔匹配测试中的表现。在所有情况下,我们发现大多数人选择的选项提供了最好的方法。使用平均置信度对一个选项的受欢迎程度进行加权并没有发现任何好处,而选择“非常受欢迎”的选项则导致准确性大幅下降。因此,我们不考虑元认知判断,而是支持对这个特定任务进行简单多数投票。
