Imagine how different your life would be if you knew when someone was lying or telling you the truth. Whether hiring a new employee, investing money, knowing when your boss is being completely up-front, finding out whether your child is being totally honest, or even dating someone new, having the ability to unmask a lie can have far-reaching and even life-altering consequences. As former CIA agents, Philip Houston, Mike Floyd and Susan Carnicero are among the world"s best at recognizing deceptive behaviour. Spy The Lie chronicles the fascinating story of how they used a methodology Houston developed to detect deception in the counter-terrorism and criminal investigation realms, and how these techniques can be applied in our daily lives. Through thrilling anecdotes from their careers in counterintelligence, the authors provide a foolproof means of identifying deceptive behaviour, showing readers how to study nuances, both verbal and non-verbal, such as putting hands to the face in response to a question; repeating a question, using qualifiers (‘basically, I…") and much, much more.
