Griffin Spy the Lie: Former CIA Officers Teach You How to Detect When Someone is Lying

Books was received in good quality

The content of this book is very good. They comprimised their practical knowledge in this book. And it actually works. It is not about being a lie detector - that does not work. And the science behind it also shows, that lie detection on a specific person can't be trusted. But this book combines detecting lies and getting the lie out through interaction. They minimize speculation and show, not to trust your bias. Their theory behind their practical knowledge also makes sense and is biological based. It is amazing, how much you can learn about lies and learn to uncover it in everydays interaction - the more important, if they lie to you, because they want to sabotage you. I also read scientific papers about this theme and try to learn from other sources. But I made the decision, most of them are actually not helpful and by far not practical. But this book is. This book actually gave me much more for the money, than I paid for (both) of their books.

easy to understand and worth of money

Fast delivery. Will purchase again

If wanna spy some lies, this is the book for you. I am outta control spying. I spot lies on the train. I spot lies on a plane. I spy lies in the eyes, sighs and thighs. Now I just need an awesome badge, some credentials and a microphone in my lapel. Old school.

After completing this book, I realized that I could have saved tens of thousands of dollars, had I read this material just one year ago. The authors explain how Time and Cluster are key components to catching a lie. They explain why and how the first five seconds (Time) following a question are crucial and how verbal and non-verbal behavior (Cluster) are important. Hence, the L-squared model: always listen and watch. If, like me, you were used to trusting too much and believing easily, this book is for you. If you want to know when someone is being deceptive or want to spare yourself some lasting regret because of your naivety, then study this book. I am a fast reader but it took me a week to finish this book as I wanted to grasp every detail and technique in it. I will read it again. We live in a beautiful world but from time to time you will bump ito deceptive people and it is your full responsibiity to protect yoursel from being taken advantage if you want to be successful. No one will proctect your interest expect yourself. So, buy and study this book.
