People who are more trusting are actually better at spotting liars than those who are more cynical. Researchers from the University of Toronto showed people job interviews of 2nd year M.B.A. students. Some of them were telling the truth while others were telling lies to improve their chances. Before they watched the videos the participants filled out questionnaires asking them how much they agreed with statements such as 'Most people are basically honest,' and 'Most people are basically good-natured and kind.' The participants who had a more optimistic view of human nature were less willing to hire liars and better able to spot them than those who were more pessimistic.
