Ninety-one detectives watched videofragments of 20 confederates who had been instructed either to tell the truth or to lie. After each videofragment the detectives indicated whether the confederate was lying. Although the study took place in a police context, and thus had higher ecological validity, the results strongly corresponded with those of previous studies: The accuracy rate was low (49%). Like the students in other deception studies, the detectives used the wrong cues to detect deception, and the actual situation (whether the confederates were telling the truth) did not predict suspiciousness.
91名侦探观看了20名被指示要么说实话要么说谎的同谋的视频片段。在每个视频片段之后，侦探们指出该同谋是否在说谎。尽管这项研究是在警方的背景下进行的，因此具有更高的生态效度，但结果与之前的研究结果高度一致：准确率很低（49%）。和其他欺骗研究中的学生一样，侦探们使用了错误的线索来检测欺骗行为，而且实际情况（同谋是否说实话）并不能预测可疑程度。
