We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers in an international airport departure hall told the truth or lied about their forthcoming trip in an interview. Their skin temperature was recorded via a thermal imaging camera. Liars' skin temperature rose significantly during the interview, whereas truth tellers' skin temperature remained constant. On the basis of these different patterns, 64% of truth tellers and 69% of liars were classified correctly. The interviewers made veracity judgements independently from the thermal recordings. The interviewers outperformed the thermal recordings and classified 72% of truth tellers and 77% of liars correctly. Accuracy rates based on the combination of thermal imaging scores and interviewers' judgements were the same as accuracy rates based on interviewers' judgements alone. Implications of the findings for the suitability of thermal imaging as a lie detection tool in airports are discussed.
我们测试了热成像作为机场筛查中谎言检测工具的准确性。在国际机场候机厅的 51 名乘客在接受采访时如实或撒谎陈述了他们即将到来的旅行。他们的皮肤温度通过热成像摄像机记录下来。说谎者的皮肤温度在采访过程中显著升高，而说实话者的皮肤温度保持不变。基于这些不同的模式，64%的说实话者和 69%的说谎者被正确分类。访谈者独立于热记录做出真实性判断。访谈者的表现优于热记录，正确分类了 72%的说实话者和 77%的说谎者。基于热成像分数和访谈者判断的组合的准确率与仅基于访谈者判断的准确率相同。讨论了这些发现对热成像作为机场谎言检测工具的适用性的影响。
