“Daniel Levitin’s field guide is a critical-thinking primer for our shrill, data-drenched age. It’s an essential tool for really understanding the texts, posts, tweets, magazines, newspapers, podcasts, op-eds, interviews, and speeches that bombard us every day. From the way averages befuddle to the logical fallacies that sneak by us, every page is enlightening.”—Charles Duhigg, author of The Power of Habit and Smarter, Faster, Better
“The world is awash with data, but not always with accurate information. A Field Guide to Lies does a terrific job of illustrating the difference between the two with precision—and delightful good humor.”—Charles Wheelan, senior lecturer and Policy Fellow, Rockefeller Center, Dartmouth College, author of Naked Economics

I really liked the author splitting his subject in three main categories: 1) evaluating numbers; 2) evaluating words; 3) how the scientific method works. Each section covers its respective subject in a thorough and entertaining way.
Within the evaluating numbers section the author covers all the ways in which visual quantitative data (graphs) can fool you. You really have to watch very carefully the scale of the X- and Y-axes to understand if someone is trying to trick you. The author does a good job of explaining the difference between correlation and causation (and how not to confuse the two). He also warns you not to confuse what is tested as statistically significant and yet can be immaterial (small differences pop up as statistically significant that have little bearing on the outcome when you have very large samples). The author also warns against extrapolating trends especially when you go outside the boundaries of the variable values you observed within the learning sample of your data set. The author covers well the various biases and errors that can affect sampling (participation bias, reporting bias, etc.). The chapter on probabilities is excellent with a well-defined differentiation between classic probabilities, frequentist probabilities, and Bayesian probabilities.
Within the evaluating words section, the author warns about understanding the actual domain narrowness of experts. He does a good job of explaining the difference between incidence and prevalence rate. He provides a very good coverage on behavioral risk perception that is so detached from probabilistic thinking.
Within the scientific method section, the author defines the different types of reasoning (deduction, induction, abduction). He also covers logic and logic notation. He also covers in greater detail Bayesian statistics. The latter is a subject that permeates every section of the book. And, he does a good job of explaining Bayes thanks to his four- quadrant framework that is really helpful in calculating the related Bayesian statistics.
The author makes just one small error where he confuses R Square with R (correlation). R Square explains how much the variance in one variable can be explained by the other variable. Meanwhile, R simply tells you the strength and the direction of the relationship between those two variables. Also, remember R is often negative (so the explanation bit here not only is wrong but is divergent) meanwhile R Square can’t be negative by definition. This is a minor typo. I know the author knows that stuff. One math typo in a 250-page book is far better than most books on the subject.
I'd love to see this book as part of a high school curriculum, to arm the next generation with the skills they need. The primer on Bayesian thinking is worth studying and keeping.
The book may be a hard read for high school students and for many readers, particularly in its discussion of statistics and probabilities which are on a college level. But the discussion at the college level is necessary in order to validate the author’s message.
While I think it is an outstanding book, I pondered over whether or not to give it a 5 star or a 4 star rating. Because it has some shortcomings, I chose to give it a 4 stars. My principle reason is the organization of the book. In the back of the book is a section which displays all the sources for the statements made in the book. In other words, a compendium of end notes. The problem, and it is a serious problem, is that the text of the book does not reference the end notes.
This is important to those like myself, who are serious about checking the sources of the statements and data mentioned in the text. I never accept an author’s statements of fact unless I can verity the source. An example is the statement in “A Field Guide” is the statement on page 17 that “The average annual temperature in Death Valley is a comfortable 77 degrees... but that the range can kill you , with temperatures ranging from 15 degrees to 134 degrees on record.” The end note gives as its reference Wikipedia. Wikipedia is not a primary source and thus not the best source. In fact, Wikipedia does not say that. It says that the mean average temperature is 77 degrees and that was not for Death Valley as a whole but at a particular location. Moreover, the extremes of 134 degrees and 15 degrees happened in 1913 and accuracy of the 134 degree reading has been challenged. (Court, 1949: How hot is Death Valley? Geographical Review, 39, pp. 214-220). Professor Court makes a compelling case that the 134 degrees reading was erroneous and when the historical data for Death Valley is examined, the 134 degrees is not plausible.
Perhaps this is minutia because all that the author is trying to establish is that a number provided by a person does not necessarily represent the actual conditions. But the author should have been more careful in picking the example and setting forth its source, partiuclarly given the subject matter of the book.
The author states that “If something appears in Nature, the Lancet, or Cell, for example, you can be sure that it went through vigorous peer review.” (P. 144) Ergo it can be trusted. Perhaps but several articles in the Economist magazine challenge this. “How science goes wrong.” (Oct 21st 2013); “What’s wrong with Science”, challenging Nature and Cell (Dec 16th 2013). My advice is never trust any publication even if it is supposedly peer reviewed, without thoroughly checking it out. Peer review often is shoddy and sporadic and it isn’t as reliable as it is cracked up to be.
The author praises Consumer Reports as a reliable source. Not so. After 55 years as a subscriber, I cancelled my subscription because I found it very unreliable. CR’s processes are subjective to a fault. Its ratings often depend on personal tastes by the person or people doing the testing. For example, a tester gives a product a poor rating because in his or her opinion the product has a cheap finish but others might prefer the finish because it is durable and to them nice looking. Moreover, when testing a product, in most cases only one sample of the product is tested. It may the one bad sample in a thousand. I can’t count the times I bought a product that was top rated by CR which turned out to be a lemon. Nor the times I purchased a product that had an average rating that turned out to be a gem. I bought an SUV 15 years ago that CR was critical of and had also given it a low reliability rating. But I tested 16 other more highly rated SUVs and did not find any of them that met my needs better than the SUV I bought. It is the best car I have ever owned and I have had only routine maintenance problems. We have had Mercedes and Cadillacs but my wife thinks this SUV has the best ride of any car we have ever owned or tested. And we got it for far less than its higher rated rivals.
Consumers Reports reliability ratings are not scientific. The annual questionnaire is subjective and we never know if the sampling is representative of the owners participating. If one goes on line and reads he product reviews by the public, public opinion of the product is almost always at variance with the ratings given to products by CR. That is because the public isn’t just testing one sample but many samples and the public is finding the faults. CR does not have the resources to test more than one sample of a product and since CR needs to publish its results quickly before the manufacturer changes models, it cannot test a product long enough to find out how reliable the product is.
In conclusion, despite its few faults, the book is outstanding. I recommend as a read for everyone.
