Imagine how different your life would be if you knew when someone was lying or telling you the truth. Whether hiring a new employee, assessing the veracity of legal testimony, investing in a financial interest, knowing when your boss is being completely up-front, ascertaining whether your child is being totally honest with you, 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 worlds 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, including: Hand(s) to the face in response to a question; Grooming gestures; Invoking religion ("I swear to God"); Repeating the question; Qualifiers ("Basically"); and much, much more.
