Ninety-nine police officers, not identified in previous research as belonging to groups that are superior in lie detection, attempted to detect truths and lies told by suspects during their videotaped police interviews. Accuracy rates were higher than those typically found in deception research and reached levels similar to those obtained by specialized lie detectors in previous research. Accuracy was positively correlated with perceived experience in interviewing suspects and with mentioning cues to detecting deceit that relate to a suspect's story. Accuracy was negatively correlated with popular stereotypical cues such as gaze aversion and fidgeting. As in previous research, accuracy and confidence were not significantly correlated, but the level of confidence was dependent on whether officers judged actual truths or actual lies and on the method by which confidence was measured.
99名警察在对嫌疑人进行录像讯问时，试图辨别嫌疑人所说的真话和假话。这些警察在以往的研究中并未被认定为属于测谎能力较强的群体。他们的准确率高于欺骗研究中的典型水平，达到了以往研究中专业测谎仪所获得的水平。准确率与在讯问嫌疑人时的感知经验以及提及与嫌疑人陈述相关的欺骗检测线索呈正相关。准确率与诸如目光回避和坐立不安等常见的刻板印象线索呈负相关。与以往的研究一样，准确率和信心之间没有显著相关性，但信心水平取决于警察判断的是实际的真话还是实际的假话，以及信心的测量方法。
