I've been reading a number of books on human behavior and marketing, and this book was extremely highly recommended, so I picked it up. I would certainly recommend this book to anybody, whether you're interested in marketing or not. The author looks at a list of factors that can unconsciously influence people's decisions. He presents the research clearly and with easily understood examples, and concludes each chapter with advice on how to identify when someone is trying to influence you in these ways, and how to defend yourself from being unwillingly influenced or pressured. He also discusses how knowledge of these ways we are influenced can be used ethically to improve our communications (both personal and in regard to marketing). A very interesting and enlightening book.
