It’s scary to imagine a world in which all people cut the truth: they would probably kill each other! Only lies can save you from aggression, anxiety, suspicion, smoothing out all acute problems. Yes, psychologists justify white lies when circumstances require it. But they oppose the endless lies that poison the lives of those around them. And they call for fighting liars with the help of special skills in recognizing lies by facial expressions and body movements of a person. They also offer to reveal his true essence by his appearance, habits, manners, and lifestyle. Having mastered the methods of famous doctors Vladimir Morozov, Paul Ekman and Alan Pease, you can easily identify a deceiver. Knowing the secret signs will help you move through life more confidently, bringing closer those you can trust and weeding out those from whom you should expect a dirty trick at any moment.
