As a Statistics teacher, I jump when I see that a new book on this subject has come out. The study of how numbers are understood and misunderstood by the public can be very fascinating indeed. Unfortunately, this book ranks slightly below average in a crowded field. Here's why:
1) The book doesn't offer a whole lot of innovative thinking on the subject. Some examples and phraseology were new, and I especially enjoyed the chapter called "The Whole Elephant" (on the foolishness of quantitative goal setting by heads of companies), but much has been rehashed in other books in some form or another.
2) I wasn't entertained. The book lacked humor, and while not what I would outright call dry, it didn't exactly come alive either.
3) Most examples were from studies related to Great Britain. This may or may not bother some people.
On the flip side, it is a very quick read, with independent chapters that can be read in 10-15 minute bites. Not a bad bathroom book, I suppose.
Better books on the subject, or related subjects: The Drunkard's Walk, Innumeracy, Damned Lies and Statistics, 200% of Nothing, Predictably Irrational, Chances Are
