Generally I'm pretty leery of books that make wild promises in the title or jacket. Claims of "I can make you happy!" or "Lose weight in 18 seconds!" to me just seem to scream SPAM - and not the curiously salty mystery meat that can last longer than most nuclear half-lives. Inherently, statements (or titles) that promise magical or miraculous results have a tang of desperation about them, and polarized, definitive statements tend to ring hollow. As a rule, I stay away from books like these. I just feel like I'm better off reading something that encourages more realistic expectations (case in point: "How to become a human lie detector in under 60 seconds" versus "An ex-FBI agent's guide to speed reading people.")
I don't know why I picked up Detect Deceit. It went against every internal guideline for appropriate book selection. It may be that the book is short, and I appreciated being able to get through something in a day or two. It may be that I was drawn to the glossy pages (I'm a kinesthetic/visual learner. It appeals to me.) There are also a lot of pictures. I like that. I'm not above admitting that I was drawn in by aesthetics more than content. At any rate, I took the book home with me. My impressions of Detect Deceit are mixed, and I'll try to be concise in explaining why.
I'll start off with the good things. Detect Deceit is a very easy read; clear cut and written in a no-nonsense fashion that still doesn't take itself too seriously. Craig has a very conversational yet direct tone that gets the information across. There isn't time to mince words - we only have 60 seconds to learn this stuff, after all! Another thing I liked about the book is the use of pictures to illustrate concepts. When you're covering a topic that relies heavily on perception and experience, I don't think you can overuse pictures and diagrams. Craig capitalizes on this and it's a strength of his book. Lastly, the author uses a very convenient acrostic to encapsulate the essential points and procedure for detecting deceit: M.A.G.I.C. I know, I know, what a fantastical term to pair with a behavioral science? Nevertheless, it does work - I won't say that it works like MAGIC, but it works. The simplicity is the elegance of Craig's content. I won't describe exactly what the acrostic represents, because then you wouldn't need to read the book. Suffice it to say, however, that the process involves establishing a baseline for people's behavior, asking specific questions in a particular style to evaluate guilt, and observing behavior. It works, I like it, and it's consistent with other books/research I've looked at. I don't think that you can stress enough the importance of establishing a baseline against which to compare abnormal or "guilt" behaviors. Anything out of context could be considered a "guilt indicator" and that's a definite point to Craig's credibility. There's also a handy summary at the end of the book that sums (literally) everything up into about 20 pages and you can use as a reference.
Now, the things I didn't really care for in the book. Firstly, reading the book (160) didn't take a ton of time, but it certainly took more than 60 seconds. Secondly, the content in Detect Deceit is good, but a little simplistic. There is no way that by the end of reading the book that I would consider myself or any other person to be an expert in lie detection. It's a good starting point, maybe; if nothing else I would consider Detect Deceit to be a sort of behavioral primer. It informs you of the basics, covers each aspect of behavior and lying to a degree, and gives you a framework within which to operate (M.A.G.I.C.) if you really do want to try to learn "catching" people in a lie. Remember though that this is an art and a science, so I honestly feel that this book, in and of itself, gives the reader a loaded gun and says "Now, be careful with this!" The simplicity of Craig's writing is also his greatest liability. I can see a lot of people making false accusations about "lies" that they caught and creating a lot of turmoil because of the M.A.G.I.C. in Detect Deceit. For that reason, I cannot find any way to support the idea that upon reading Detect Deceit I, or any other reader would now be a "human lie detector." At most I would call it being "mildly informed."
So, at the end of this review, what can I really say? Detect Deceit is a good, easy, quick (more than 60 seconds) read. It does what it can do in 160 pages very well - gives the reader an introduction to deception and how to determine if someone is telling the truth. However, that's about all that it can do in 160 pages. This book is a springboard, a primer, a jumping-off point (I'm lacking in other metaphors) and hopefully it spurs the reader on to other works that can then elaborate on the skeleton of knowledge (ah! one more metaphor!) Craig sets in place. So, if you know absolutely nothing about deception, Dectect Deceit is a good place to start. But please, whatever you do, don't stop there and call yourself a "lie detector!"
