I do my best to tell the truth. But when I slip up and tell a lie, do my eye movements give me away?

A popular belief is that liars tend to look up and to the right when they are making something up. To test this, a group of researchers tracked the eye movements of volunteers who had been told to either lie or tell the truth. They found no major differences between eye movements, disproving the idea.
