Most adults and teens would greatly benefit from reading this book, especially now that we live in a world where "fake news" is a dire problem. Don't take what you read or hear at face value - really think about it, and decide if what you are reading makes sense. Daniel J. Levitin spells out exactly how (and why) to do that.
For me, some of this was very basic, some of it was review, and some of it was completely new. All of it was useful. It had the added advantage of being easy to read and easy to understand. Almost every segment would start with Levitin presenting a claim and then evaluating the claim for its truthiness. He takes many facets of information dissemination to task - from the various types of information found on the internet to respected news organizations to doctors to scientific journals. It really is something of a field guide as well; I consider myself to be a decent critical thinker, but there were several tips and tricks that I plan to use in the future that I never would've considered had I not read this book. Levitin does a really great job of being non-partisan - he goes out of his way not to come down on one side or another on any issue, he merely evaluates the truth of different assertions (and if he points out the lies on one side of the political aisle, he quickly follows with a lie from the opposing side).
As someone who works at a library, I think information literacy is crucially important. It's even more important today as more and more specious information becomes available through the internet. This book will show you how to sift through the lies and find the truth, an essential skill for everyone. 5 stars.
