We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers an international departure hall told truth or lied about their forthcoming trip interview. Their skin temperature was recorded via camera. Liars' rose significantly during interview, whereas tellers' remained constant. On basis these different patterns, 64% tellers and 69% liars were classified correctly. The interviewers made veracity judgements independently from recordings. outperformed recordings 72% 77% Accuracy rates based on combination scores interviewers' same alone. Implications findings for suitability airports are discussed.
