Learn to apply lie-detection skills to your everyday life with this easy-to-follow guide. 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.
