Deception is a significant and pervasive social phenomenon. At the same time, technologies have suffused almost all aspects of human communication. The intersection between deception and information technology gives rise to many questions about deception in the digital age. How does communication technology change the way we lie? Why and how do people lie in online relationships? Can people detect if they are being lied to in an email? Can computer programs identify word patterns that reveal whether someone is lying or not? This talk will examine these questions and describe some recent research that may shed some light on the answers.
