How we Catch a Liar


The wide applications and benefits of this emotion based training are outlined by Dr Ekman as follows: "In any transaction that matters whether it's between lovers, between parent and child, between salesman and client, between doctor and patient, between suspect and interrogator, between adversaries at an election, emotion is what we're looking for. Emotions tell us what matters."
