I bought this book after reading a lengthy newspaper article based on an interview with the author. His approach to negotiating appeared far more intelligent and perceptive than other authors on the subject. Unfortunately, within a chapter or so of this book it had already become clear that 80% of the information and ideas it contains were present in the original 1000-word interview.
So essentially, this book is an excellent 2000-word essay inflated to a nauseating 80000-word paperback through endless repetition. The book is saturated with "real-life examples" from students that he has taught. Examples might conceivably be useful as a means of exploring his ideas in greater depth if they were deconstructed, or used as a means to analyse subtle mistakes in negotiation. But they don't -- they are all superficial, happy-ending retellings of the same storyline: "I had this student once, they used my ideas brilliantly in some negotiation, and now they are rich and happy!". These intrude constantly on the narrative, so that after the first half-dozen, it feels as though the programme is interrupted every five minutes by yet another commercial for a product I have already paid for.
Presumably Stuart Diamond fell victim to the familiar publisher's belief that customers think that 2000 words repeated 40 times is worth 40 times more, and that everything has to be crammed into a familiar, fashionable format. Indeed, traces of the publisher's interference are regularly evident, which is never a good sign. For instance, Diamond states, more than once (as with everything else he states) that the book is called "Getting More" not "Getting Everything" because it is central to his approach that one should do what they can to improve their chances of a successful negotiation, but accept that they cannot succeed in every instance. So what did his publishers choose to add as a subtitle? "Get what you want every time." It's as if they hadn't read the actual book -- and maybe they haven't.
