We examined the Devil's Advocate lie detection method which is aimed at detecting lying about opinions. In this approach, participants give reasons for why they hold an opinion in the eliciting-opinion question and counter-arguments to their opinion in a devil's advocate question. Truth tellers (n = 55) reported their true opinion about protestor actions, whereas lie tellers (n = 55) reported the opposite of their true opinion. Answers were coded for number of arguments and plausibility, immediacy, clarity and scriptedness. Data were analysed with analyses of variance with veracity being the sole factor. Supporting the hypothesis, truth tellers provided more pro-arguments than lie tellers and to all eliciting-opinion questions their answers sounded more plausible, immediate and clear than lie tellers' answers. The opposite pattern was predicted for the devil's advocate question but not found, likely caused by the simplification of the question. Neither was being scripted a diagnostic veracity indicator.
我们研究了旨在检测关于观点的说谎行为的“唱反调”测谎方法。在这种方法中，参与者在引出观点的问题中给出他们持有某种观点的理由，并在“唱反调”问题中给出与其观点相反的论据。说真话者（n = 55）报告了他们对抗议者行动的真实看法，而说谎者（n = 55）报告的是与其真实看法相反的观点。对回答的论据数量、合理性、即时性、清晰度和是否照本宣科进行了编码。以真实性为唯一因素进行方差分析来分析数据。支持该假设的是，说真话者比说谎者提供了更多的支持性论据，并且对于所有引出观点的问题，他们的回答听起来比说谎者的回答更合理、更即时、更清晰。对于“唱反调”问题，预测的情况相反，但未发现，这可能是由于问题简化所致。照本宣科也不是诊断真实性的指标。
