To properly evaluate different forensic techniques, it is important to know how reliable these different techniques are. The reliability of scent identification line-ups is unknown. The purpose of this study was to describe, and employ, a reliability testing method for scent identifications using trained police dogs and a novel scent identification procedure. Two kinds of experiments were prepared: suspect = perpetrator experiments, and suspect not equal to perpetrator experiments. Six dog/handler teams participated in 10 experiments, five of each kind. The reliability of an identification, or the diagnostic ratio, is the percentage correct identification in suspect = perpetrator experiments divided by the percentage false identification of the suspect in suspect not equal to perpetrator experiments. Factors that influence the reliability of scent identifications are discussed, and the results of the scent identifications are compared with recent reliability estimates of other forensic techniques.
为了正确评估不同的法医技术，了解这些不同技术的可靠性很重要。气味识别列队的可靠性尚不清楚。本研究的目的是描述并采用一种使用训练有素的警犬和新颖气味识别程序的气味识别可靠性测试方法。准备了两种实验：嫌疑人=作案人的实验和嫌疑人≠作案人的实验。六个警犬/训导员小组参与了10次实验，每种实验各5次。识别的可靠性，即诊断率，是嫌疑人=作案人实验中正确识别的百分比除以嫌疑人≠作案人实验中对嫌疑人错误识别的百分比。讨论了影响气味识别可靠性的因素，并将气味识别结果与其他法医技术最近的可靠性估计进行了比较。
