Can You Spot The Liar In The Photo?

How good are you at picking out fibbers from a crowd? According to a new paper from researchers at the University of Rochester, New York, there are particular (involuntary) quirks and facial movements that give us away – whether we like it or not. The team used a combination of big data, machine learning technology, and automated facial feature analysis software to identify differences in facial and verbal cues between people who are lying and people who are telling the truth. Volunteers were recruited from Amazon Mechanical Turk and split into pairs. In total, there were 151 couples and 1.3 million frames of expressions for the team to analyze.
