The Fallacy Detective by Nathaniel Bluedorn and Hans Bluedorn*

Thirty-Eight Lessons on How to Recognize Bad Reasoning
These two brothers have written a stellar book that has the potential to be used as philosophy, critical thinking and logic curriculum!
First they share how to develop an inquiring mind and then they delve into four main categories of "bad reasoning": 1. avoiding the question 2. making assumptions 3. statistical fallacies 4. propaganda.
Under each of these categories they explain different methods that our society uses (ie "red herring", "circular reasoning", "weak analogy", "bandwagon" etc-many, many more!).
What I liked best was after each explanation, they provide scenarios and the reader must determine which bad reasoning is being used.  They include prior bad reasoning examples so one receives lots of practice of discerning which fallacy is being employed.  Of course, they supply an answer key in the back.
Another perk is they have created a test for teachers to give to their students if they want to utilize this book in a classroom!
Description of a fallacy game is included.
-Borrowed from the library (but I want to buy this book!).
**Highly, highly recommend.
Recommended ages: ages 12 through adult.
