Frank Abagnale Jr, the confidence trickster who inspired the film "Catch Me If You Can", later became a security consultant for the FBI. There's intuitive logic to the agency's recruitment strategy - if you want to catch con artists, who better to spot them than a master con artist?

But does this logic apply at a more basic level? Do skilled liars really make skilled lie detectors? A pioneering study reported on our Research Digest suggests they do.
