Who should join the suspect in a police photo array?

传统的警察列队往往产生不准确的决定，证人未能挑选罪犯或挑选无辜的嫌疑人。令人惊讶的是，尽管在收集目击者证据方面取得了所有的科学进步，但在选择嫌疑人的“填充物”方面绝对没有客观的依据。指南只是建议填充物不应该与嫌疑人太相似或太不相似。然而，填充物很可能对决策准确性产生至关重要的影响。该项目旨在通过开发和测试一种灵活且普遍适用的照片阵列合成方法来弥补这一显著缺陷，该方法将优化判断的可辨别性并减少偏见。

The traditional police line-up often produces inaccurate decisions, with witnesses failing to pick the culprit or picking an innocent suspect. Surprisingly, despite all the scientific advances with respect to the collection of eyewitness evidence, there is absolutely no objective basis for selecting the ‘fillers’ to accompany the suspect in the line-up. Guidelines merely suggest the fillers should not be too similar or too dissimilar to the suspect. However, the fillers are likely to have a crucial influence on decision accuracy. This project aims to remedy this striking deficiency by developing and testing a flexible and universally applicable methodology for photo array composition that will optimise judgmental discriminability and curtail bias.
