Why do we lie? Are we all liars? Do animals lie? Are there contexts that encourage lying? Are there individuals who are more talented in lying than others? What is a successful lie? And also, how can we know if someone is lying to us?

Written in clear and concise language, this book presents the current state of research in psychology and in cognitive neuroscience on all these questions and on those recently raised by the appearance of lies on the internet and social media.

At a time when some suggest that when people tell lies they are simply expressing a difference of opinion, here is a particularly welcome work on the underbelly of lies, and on their possible detection.
