You are an extraordinary being, experiencing a wide spectrum of thoughts and emotions, from falling in love, recalling last Tuesday's events, and contemplating the meaning of life, to solving complex equations. You also engage in an almost infinite array of behaviors, such as walking down the street, juggling tennis balls, singing loudly off-key, or riding a unicycle. Psychology is the study of these things: how we think, feel, and behave, what makes each of us unique, and what we, as humans, have in common. Richard Wiseman, a psychologist, bestselling author, and YouTube star, believes psychology is fundamentally important in five key areas: it fosters critical thinking, reveals the hidden mechanisms of the mind, debunks common and harmful myths about human behavior, provides vital material for enriching discussions in politics, education, medicine, and other fields, and can be used to develop ourselves and our societies. If you've ever wondered why we fail to see what's directly in front of us, how to spot a liar, the secret to happiness, or how to build a more altruistic society, you'll find the answers to all your questions in this book. "This engaging and accurate introduction is perfect for those wondering what psychology is truly about." - Uta Frith, University College London. "A wonderful book. No one is better than Richard Wiseman to write about what psychology offers and what it doesn't. The quality of writing and the research presented are excellent." - Cara Flanagan, co-author of the bestselling book series.
