Lie detection procedures are typically aimed at determining guilt or innocence of a single suspect. Serious security threats, however, often involve groups, such as terrorist networks or criminal organizations. In this report, we describe a variant of the skin conductance-based Concealed Information Test (CIT) that allows for the extraction of critical information from such groups. Twelve participants were given information about an upcoming (mock) terrorist attack, with specific instructions not to reveal this information to anyone. Next, each subject was subjected to a CIT, with questions pertaining to the details of the attack. Results showed that for every question, the average skin conductance response to the correct answer option differed significantly (p < 0.05) from those to all other options. These results show that the information about the upcoming attack could be extracted from the group of terror suspects as a whole.
测谎程序通常旨在确定单个嫌疑人是否有罪。然而，严重的安全威胁往往涉及团体，如恐怖网络或犯罪组织。在本报告中，我们描述了一种基于皮肤电传导的隐蔽信息测试（CIT）变体，该变体能够从此类团体中提取关键信息。12名参与者被告知即将发生的（模拟）恐怖袭击信息，并被明确指示不得向任何人透露此信息。接下来，对每个受试者进行CIT测试，问题涉及袭击的细节。结果表明，对于每个问题，对正确答案选项的平均皮肤电传导反应与对所有其他选项的反应存在显著差异（p < 0.05）。这些结果表明，可以从整个恐怖嫌疑人团体中提取有关即将发生袭击的信息。
