I wanted to like this book but the open Never judge a book by its cover or, in this case, by its title.
Glenn Morgan check this link for a full description on why this is …more Nabila coincidence and absolute certainty are two very different concepts. He also does a great job pointing out the negative impact of innumeracy on society in general – how misunderstandings about things like coincidence and cause and effect can lead lnnumeracy harmful beliefs and behaviors about things like the pseudosciences, gambling, and healthcare.
Innumeracy: Mathematical Illiteracy and Its Consequences
Retrieved from ” https: Feb 28, Ken Ransom rated it it was ok. Paulos heaps on many marvelous examples of how we misapprehend risk and misinterpret data and generally make a muddle of many things having to do with numbers. Paperbackpages. I appreciate that Paulos repeats a great piece of wisdom my college advisor once told me: And as computers take over more and more of the calculations needed during our lives, I don’t see where this lack is going to be dealt with in the near future.
If an initial large absolute difference arises due to chance, it’s not likely to go away. That correlation and causality are not equal. One imagines that it could have been done much much! Slipping between millions and billions or between billions and trillions should in this sense be equally funny, but it isn”t, because we too often lack an intuitive feeling for these numbers.

The maths are fun for those that can follow Paulos, but in his mad rush he covers a great deal of ground one imagines the innumerate might have some difficulty in keeping up.
He is trying to segue into other reasons for innumeracy, but fumbles, because to make the strongest logical statement, he should have said, “Still, it’s not the whole story, since innumdracy are many quite numerate people who have had such poor mathematical education. But if the reader will stick with it, or maybe skip over sections not understood, it’s worth the time spent reading. I capitoli del libro spaziano su vari temi.
Too many are not mathematically capable nor are they interested in teaching mathematics beyond the basics. This doesn’t mean that one side or the other is necessarily likely to get that far ahead – but if someone DOES, by pure chance, then they’re likely to stay ahead.
It was complete, and left me feeling more knowledgeable.
Paulos speaks of “statistically meaningless”, forgetting that this terminology is already enough to throw off most of his innumerate readers.
Tiene una cosa buena este libro y es que es un buen libro para recordar temas de probabilidad avanzada. I had never thought of it quite like that.
I find this is true in personal finance — not understanding the incredible scalable power of compound interestfor example, or in public finance — not grasping the power of large numbers when it comes to the national debt. Preview — Innumeracy by John Allen Paulos. If newspapers and TV started to use this kind of scale, it would be an easier way for people to compare the relative risk of various activities. Your email address will not be published. That numbers are utilized, they are automatically ‘mathematical’ and it scares people off.
Apr 15, Gina rated it it was ok. For example, when describing magnitude he says, a million seconds is about eleven and a half days, but a billion seconds is almost thirty-two years! I had been reading an article a couple months ago about what could be basically called the mathematical illiteracy of our society. Paulos mathematics, Temple U. Innumeracy, an inability to deal comfortably with the fundamental notions of number and chance, plagues far too many otherwise knowledgeable citizens.
It serves as an excellent antidote to tedious classroom lectures on the difference between inverse and direct proportions. I also liked his discussion of coincidences – for example, hearing in the morning that vivid details of your previous night’s dream match what you hear on the news.

Paulos does consider both the causes and the possible ways to decrease the prevalence of innumeracy, but his discussion and suggestions are necessarily barely elaborated on he has a lot to innumsracy to in this short book. The latter is a quite fascinating and useful idea — and relevant to much that he writes about — but some of the many asides and tangents, and the fast pace, make even numerate heads spin. For example, the fortune telling psychic’s few correct and general observations are remembered over the many incorrect guesses.
No system of thought, however powerful, is without its weaknesses. Now, if we reward good performance and punish poor performance, and regression to the mean occurs, we are likely to assume that punishment causes improvement while praise causes a lapse – even if the punishment or reward had no effect on the next day’s performance.
Say that each of us tends to perform at some mean level on a particular task for example, if I throw darts, assume I’ll tend to hit near the bullseye 10 times out of So the fact that this has occasionally happened to you or someone you know should not be surprising in the least. That’s true to a point, but there are many factors that can affect that besides normal ups and downs – amount of practice, sore muscles, more aggressive guarding.
My takeaway is to return to the fun parts of math that attracted me to the subject in the first place puzzles and gamesand an incentive to explain concepts to newcomers. He has received awards in: His stated purpose is to appeal to innumerates with enjoyable and illuminating examples of everyday, as well as fanciful, uses of mathematics. The understatement, however, is symptomatic of a pervasive innumeracy which ill suits a technologically based society.
