Detecting deception through facial expressions in a dataset of videotaped interviews: A comparison between human judges and machine learning models

In the last decades, research has claimed facial micro-expressions are a reliable means to detect deception. However, experimental results showed that trained and naïve human judges observing facial micro-expressions can distinguish liars from truth-tellers with an accuracy just slightly above the chance level. More promising results recently came from the field of artificial intelligence, in which machine learning (ML) techniques are used to...
