“In a study of the components of lying,2 Harvard Business School professor Deepak Malhotra and his coauthors found that, on average, liars use more words than truth tellers and use far more third-person pronouns. They start talking about him, her, it, one, they, and their rather than I, in order to put some distance between themselves and the lie. And they discovered that liars tend to speak in more complex sentences in an attempt to win over their suspicious counterparts. It’s what W. C. Fields meant when he talked about baffling someone with bullshit. The researchers dubbed this the Pinocchio Effect because, just like Pinocchio’s nose, the number of words grew along with the lie. People who are lying are, understandably, more worried about being believed, so they work harder—too hard, as it were—at being believable.”
