It's one thing to continue educating myself with book such as these, and make headway towards being fooled less and less by ridiculous statistics and pseudoscience in general. It's another to have it delivered by a clever, snarky individual to make the reading pleasure even more profound. I seriously enjoyed this one. ( ) Similar to Charles Seife's Proofiness, John Paulos discuss the devasting consequences of how innumeracy - people's inability to comprehend very large numbers - could be. Innumeracy could lead to susceptibility to pseudoscience. Unlike Seife's book, the quality of this book is severely lacking. Other than the short about the author section indicating that the author is a professor of mathematics, this book does not have a bibliography or an index. As someone who has background knowledge of mathematics, I was able to understand and appreciate the complexities of the issues discussed. This book could not be assigned to high school students as the language is very technical and heavy with statistics. It is difficult to follow the amount of data given. To a high school student with insufficient math background, this book may as well be written in a foreign language. My reactions to reading this book in 1993. An entertaining, funny, and very informative book. There were some things I did know like the difference between correlation and causality, the filtering effect of pseudosciences (only remembering your seemingly pre-cognitive feelings and dreams – not all the ones that didn’t come true), and a lot of things I didn’t know (mainly all sorts of mathematical paradoxes which are demonstrably true but go against common sense), and some things I always wondered about (like just how many “precognitive” dreams you’d get in the U.S. if only 1 dream in 10,000 came “true”?). Paulos is straightforward and full of witty, relevant examples which show the relevance of law to politics (the non-transistive situations of voting such as A>B>C but C beats A in the election), the law (probability in polygraphs, drug tests, and trials), medicine, and psychology (for instance, should you get discouraged when the doctor says you test positive for a fatal disease). Paulos exposes innumeracy in a wide variety of areas, highlights misuse of statistics and shows how vital a seemingly dry subject can be. I also think he’s right on in denouncing the way math is taught (with elementary school teachers being particularly bad). I also think he’s right to scoff at people who want to be called educated but can’t reason even a little bit mathematically. My only quibble with this book is oddly, even though I’m only seminummerate, I would have liked some equations formally showing a principle. I can understand, given his audience, why he didn’t put any in though. On one hand, everybody should be made to read this book. It gives nice examples about how statistics work and what numbers actually mean. This is especially important in this day and age where statistics are so misused as to mean something completely different than what is actually shown (Republican claims vs Democrats claims using the same statistics!) I have a good understanding of how numbers work, but there were a few eye-opening discussions here (See Effective Results of a Cancer drug or 50% off of 50% is not 100 %). One thing, this book uses a lot of math to make the its case. While the math is very valid and essential in statistics, it can bog down the reading. Luckily, the author is able to sum up what the math means in word form. This book is definitely dated. But all the points made are still valid today, maybe even more so where media sensationalized most stories, without very much content. An incredibly fun read, especially considering the subject and my own mathematical deficiencies. This was on my "to read" list for far too long; many less deserving books made it to the top of the pile, probably because I was uncomfortable facing my own shortcomings. I really had only one problem with it, a nitpick, I suppose, but enough of one to rob it of a full fifth star. It was just one passage in the course of dismissing charlatanism of one sort or another where Paulos off-handedly dismisses "simpleminded atheism." He does so in the context of advocating agnosticism as the more reasonable position. It was the kind of dismissal made by the smug and self-righteous. Perhaps he meant something specific by "simpleminded atheism"? Since he doesn't distinguish it from perfectly reasonable simple atheism, it's hard to know. A predilection for agnosticism, insufficiently justified, indicates a kind of insidious, mush-brained tolerance for magical bullshit that is particularly out of place in this book. That one passage aside, I was bucked up and more than a little inspired to hone those limited mathematical chops I do possess.
Mr. Paulos is the sort of person who, when he hears that something or other is selling at a fraction of its normal cost, is likely to remark ''that the fraction is probably 4/3.'' He writes that this is often greeted by ''a blank stare.'' He takes it to be one of incomprehension, but a reader of ''Innumeracy'' may suspect behind the look an impulse to throttle Mr. Paulos. Still, there is so much of value in his book that one can easily restrain such an urge. He takes us a couple of steps closer to numeracy, and it is all in all an enlightening place to be.

This is the book that made "innumeracy" a household word, at least in some households. Paulos admits that "at least part of the motivation for any book is anger, and this book is no exception. I'm distressed by a society which depends so completely on mathematics and science and yet seems to indifferent to the innumeracy and scientific illiteracy of so many of its citizens." |
