Amazon.com Review

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."

But that is not all that drives him. The difference between our pretensions and reality is absurd and humorous, and the numerate can see this better than those who don't speak math. "I think there's something of the divine in these feelings of our absurdity, and they should be cherished, not avoided."

Paulos is not entirely successful at balancing anger and absurdity, but he tries. His diatribes against astrology, bad math education, Freud, and willful ignorance are leavened with jokes, mathematical or the sort (he claims) favored by the numerate.

It remains to be seen if Innumeracy will indeed be able, as Hofstadter hoped, to "help launch a revolution in math education that would do for innumeracy what Sabin and Salk did for polio"--but many of the improvements Paulos suggested have come to pass within 10 years. Only time will tell if the generation raised on these new principles is more resistant to innumeracy--and need only worry about being incomputable. --Mary Ellen Curtin --This text refers to an out of print or unavailable edition of this title.

5.0 out of 5 stars GOOD ANALYSIS, GREAT ANECDOTES ABOUT THE VALUE OF NUMERACY, April 3, 2004

By	Denis Benchimol Minev "Amazonia" (Manaus, Amazonas, Brazil) - See all my reviews

In this short book, Paulos does an outstanding job of pointing out what lack of number intimacy can do to a person. The anecdotes are outstanding, especially the ones on large numbers and on probability. For example, he shows how one is fooled by probability: If we have 23 people in a room, what is the probability that two of them have the same birthday? 50%!! Very conterintuitive.

The author also tries to understand why it is almost considered acceptable for a person to admit that one is "bad with numbers", while it not being ok to be "bad with words". The realm of psychology is not his forte, but the ideas he points to are interesting.

Overall, this is an easy to read book, much easier even to one literate with numbers. I was done with it in 3 hours, and was left wanting more, so much so that I am now buying some more of his works. If they are half as good as Innumeracy, then they will be good enough.

5.0 out of 5 stars lifting the shackles of cultural innumeracy, February 15, 2001

By	A. G. Plumb "Greg Plumb" (Melbourne, Australia) - See all my reviews (REAL NAME)

This review is from: Innumeracy: Mathematical Illiteracy and Its Consequences (Vintage) (Paperback)

I read this book several years ago and believe it to be a classic that would enhance any mathematics study course by making it topical and a part of the reader/student's everyday environment. What mathematics teaching needs is humanising - this book could go some way towards doing this.

This short review follows a review I have just written for 'I Think Therefore I Laugh' - another of Mr Paulos' books. Because I rate 'Innumeracy' so highly I decided to look at Customer Reviews for it, and found some clashed with my own assessment.

Some reviewrs are offended by Mr Paulos' perceived attitude towards the innumerate - believing that he is condescending in an off-putting way. I don't see it that way except inasmuch as we are all innumerate at some level and have to learn to become more numerate - just as a golfer has to learn to read the cut of the green if they want to be a good putter. And numeracy skills will certainly enhance the way we see the world and respond to its mysteries as Mr Paulos shows so cleary.

3.0 out of 5 stars interesting book, but lacking focus, March 8, 2004

By	Nadyne Mielke (Mountain View, CA USA) - See all my reviews (REAL NAME)

The problem that resulted in this book is far-reaching: the public simply doesn't understand mathematics. Statistics, ranging from a 10%-off sale to the sort found in opinion polls, are unfathomable to the general populace. Probability, especially in the context of gambling, is understood by only a scant handful of people. The list of misunderstood mathematics is nearly endless.

In the first few chapters of the book, Paulos describes various issues that the innumerate (that is, those who don't understand numbers and math) often have issues understanding. He describes the issue to a reasonable level of detail, then derives answers for them. Don't let the use of the word 'derive' scare you off: the answers are readable and readily understandable to a general audience. In some cases, if you're really rusty, you might need to read them a second time to grasp the solution.

Later chapters, however, are not written for the innumerate. They are attempts to convince the reader that mathematical education needs to be improved. I think that everyone agrees that education should be improved, but he offers suggestions that are impractical or nonsensical.

Ultimately, the problem of this book is a lack of focus. Paulos could have written either a book that tackles basic mathematical issues that the general public doesn't understand, or he could have written a book that describes the consequences of innumeracy. He tried to do both, and stuffed both topics into a single slim volume. In doing so, he shortchanges both audiences. The result is a book that is good, but does not fully address the needs of anyone.

If you find yourself uncomfortable with mathematics, pick up a copy of this book and read up to chapter five. If you are comfortable with mathematics and are looking for fodder to prove the point that improving mathematical knowledge at any level is productive, this book will not serve your purpose.
