Lying is a normal part of human communication and is sometimes necessary to protect someone's feelings. At the same time, there are also malicious lies meant to deceive, cheat, and defraud. Especially in today's world, in which technology, media, and the government have blurred the lines between fact and fiction, you can't always rely on what comes out of someone's mouth or what you see on the internet or television. It doesn't take mind-reading superpowers to be able to tell when someone is lying--but it does take special skills and a little practice. In How to Become a Human Shit Detector, international expert in undercover operations Dr. David Craig provides readers with an easy-to-follow guide on applying lie-detection skills to your everyday life. From the simple skills of bargaining, making a purchase, or dealing with children, to the more serious business of negotiating a contract, identifying infidelity, or understanding lies in politics, Craig delivers simple but effective tips and techniques we can all use to see behind the fa ade and find our way to the truth. The culmination of more than twenty years of practical criminology and hundreds of hours of academic research, this book is the premier guide to the art of lie-detecting. Split into three parts, the book looks at understanding lies and how to detect lies, and it includes an easy reference section that summarizes all the main points. The mystery of what a person is really thinking is finally unlocked in this fascinating and informative book.
