Digital Detectives: Websleuthing Reduces Eyewitness Identification Accuracy in Police Lineups (dataset).xlsx

This dataset was used for the analysis in the article Digital Detectives: Websleuthing Reduces Eyewitness Identification Accuracy in Police Lineups. 

The article explores whether searching for a culprit on social media affects eyewitnesses' subsequent identification accuracy in a police lineup.

Results showed a significant association between social media exposure and lineup accuracy for the Target Present lineup (30% more of the participants who saw the lookalike on social media failed to positively identify the culprit than participants in the other conditions), but for the Target Absent lineup (which also included the lookalike) there was no significant association with lineup identification accuracy. 

The results suggest that if an eyewitness sees a lookalike (where they are expecting to see the culprit) when conducting a self-directed search on social media, they are less likely to subsequently identify the culprit in the formal ID procedure.

The dataset includes demographics, response type and accuracy, and confidence ratings data for each of the participant conditions.

本数据集被应用于《数字侦探：社交媒体搜索降低目击者在警察 lineup 中的识别准确度》一文的实证分析。该文探讨了在社交媒体上搜寻嫌疑人是否会影响目击者在警察 lineup 中的后续识别准确度。研究结果揭示了社交媒体接触与目标存在 lineup（其中30%更多的参与者因在社交媒体上看到相似人而在正式识别程序中未能正确识别嫌疑人）的识别准确度之间存在显著关联，而对于目标不存在 lineup（同样包括相似人）而言，则未发现其与 lineup 识别准确度之间存在显著关联。研究结果提示，当目击者在社交媒体上进行自我导向搜索时，若看到与其预期中嫌疑人相似的个体，则他们在正式识别程序中识别嫌疑人的可能性较低。该数据集包含了针对每个参与者条件的人口统计学、响应类型及准确度，以及信心评分数据。
