This book delves into the world of alternative medicine and related phenomena in several different ways, both from a scientific perspective and the perspective of supporters and practitioners of those phenomena.

An attempt is made to explain not only what those perspectives are, but also why they are often so radically different. Why do lots of people believe things that other people don't? To find answers, we don't just examine the things people believe in or not, but also human traits in thinking, reasoning and belief.
