Previously Published as A Field Guide to Lies
We’re surrounded by fringe theories, fake news, and pseudo-facts. These lies are getting repeated. New York Times bestselling author Daniel Levitin shows how to disarm these socially devastating inventions and get the American mind back on track. Here are the fundamental lessons in critical thinking that we need to know and share now.
Investigating numerical misinformation, Daniel Levitin shows how mishandled statistics and graphs can give a grossly distorted perspective and lead us to terrible decisions. Wordy arguments on the other hand can easily be persuasive as they drift away from the facts in an appealing yet misguided way. The steps we can take to better evaluate news, advertisements, and reports are clearly detailed. Ultimately, Levitin turns to what underlies our ability to determine if something is true or false: the scientific method. He grapples with the limits of what we can and cannot know. Case studies are offered to demonstrate the applications of logical thinking to quite varied settings, spanning courtroom testimony, medical decision making, magic, modern physics, and conspiracy theories.
This urgently needed book enables us to avoid the extremes of passive gullibility and cynical rejection. As Levitin attests: Truth matters. A post-truth era is an era of willful irrationality, reversing all the great advances humankind has made. Euphemisms like “fringe theories,” “extreme views,” “alt truth,” and even “fake news” can literally be dangerous. Let's call lies what they are and catch those making them in the act.

All around excellent
I have read numerous books on this subject. Many of them have too many errors, focus on trivial considerations or arcane mathematical technicalities, and few cover the important subject of applying critical thinking not only to numbers but words (logic, reasoning protocol, etc.). Given that, this is one of the very best books on the topic I have read yet.
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.

A must read in this foggy world
By Faik Cem ARI
There’s an old saying that “a day will come when one won’t believe what his one has seen is the one what the other one has seen”. I believe that day is today. In order to know and to believe that -for this moment- what I know is the real known known I must think critically and search for the truth. This is the book that helps and encourages people who want to know the truth to be scientifically oriented and to be sceptic. As another saying tells: “Don’t even trust your father”.
