By questionnaire, 631 police investigators reported on their interrogation beliefs and practices-the first such survey ever conducted. Overall, participants estimated that they were 77% accurate at truth and lie detection, that 81% of suspects waive Miranda rights, that the mean length of interrogation is 1.6 hours, and that they elicit self-incriminating statements from 68% of suspects, 4.78% from innocents. Overall, 81% felt that interrogations should be recorded. As for self-reported usage of various interrogation tactics, the most common were to physically isolate suspects, identify contradictions in suspects' accounts, establish rapport, confront suspects with evidence of their guilt, and appeal to self-interests. Results were discussed for their consistency with prior research, policy implications, and methodological shortcomings.
通过问卷调查，631名警方调查人员报告了他们的审讯理念和做法——这是有史以来首次进行此类调查。总体而言，参与者估计他们在辨别真话和谎言方面的准确率为77%，81%的嫌疑人放弃米兰达权利，审讯的平均时长为1.6小时，他们能从68%的嫌疑人那里获取自证有罪的陈述，从4.78%的无辜者那里获取此类陈述。总体而言，81%的人认为审讯应该进行记录。至于自我报告的各种审讯策略的使用情况，最常见的是将嫌疑人进行身体隔离、找出嫌疑人陈述中的矛盾之处、建立融洽关系、用嫌疑人有罪的证据与其对质以及诉诸自身利益。讨论了这些结果与先前研究的一致性、政策含义以及方法上的不足。
