QUOTE : According to a 2002 University of Massachusetts study, 60 percent of adults will lie at least once within the course of a ten-minute conversation, with the average number of lies from the liars being three. And that is only what people admitted to. (If you are wondering, in this study men and women lied at about the same rate.) I don’t think there is any single number that captures how much people lie, as that depends greatly on context. Nonetheless, lying is rather deeply embedded in human nature.
