What is a fallacy? A fallacy is an error in logic -- a place where someone has made a mistake in his thinking.

This is an easy book for learning to spot common errors in reasoning.

For ages twelve through adult.

Fun to use -- learn skills you can use right away.

Exercises with answer key.

Review

I love your book! I never knew how much fun logic was until I read your book. P.S. I am 12 years old. --Paul Muenzler -- Student

I'm always delighted when two sides that seem mutually opposed come together in harmonious agreement. I'm even more delighted when I've taken one of those sides. In this case, I write of the efforts of Nathaniel and Hans Bluedorn, brothers from Iowa who advocate homeschooling and create educational materials from a Christian worldview. The fruit of the latest Bluedorn effort is a short text, The Fallacy Detective, designed to be a primer in logic for older children, specifically homeschooled Christian children, though the book is intended for anyone who wants to explore the subject. . . . I find it wonderful that the Bluedorns, among others, are actively reinvigorating the religious world with a healthy dose of independent thought . . . --Andrew C. Thomas -- The Tech, Massachusetts Institute of Technology

My family and I are really enjoying your book. Even my youngest son, who is eight, enjoys attempting to answer the questions. Your book was a great introduction to another program that I had purchased. Going directly into that program probably would have bored my children to tears but now they are interested in the concepts of logic. My children became instantly attracted to the program because of the the comic segments but later couldn't put it down. --LaVera, MD -- Parent

About the Author

In 1999 Nathaniel Bluedorn and Hans Bluedorn decided to try to turn their interest in logic into a livelihood by starting FallacyDetective.com. Since then, they have written two books on logic for children and adults, The Fallacy Detective and The Thinking Toolbox.

5.0 out of 5 stars critical thinking awesomeness, October 26, 2009
This review is from: The Fallacy Detective: Thirty-Eight Lessons on How to Recognize Bad Reasoning (Paperback)
Have you ever watched a political commercial or read a magazine ad and come away perplexed? You knew that you were being bamboozled, that the ads were somehow deceptive ... but you couln't quite put your finger on why?

The Fallacy Detective will help you get to the bottom of the many logical fallacies you encounter every day. Using Socratic teaching methods including lists of examples that are discussed and identified at the end of every chapter, you and your child will learn to easily recognize everything from Red Herrings and Straw Men to Ad Hominem attacks ... and many other attempts to lead you in the wrong direction logically. And a fallacy recognized, is a fallacy thwarted.

5.0 out of 5 stars My 14 year old read The Fallacy Detective like it was a novel., January 7, 2010
This review is from: The Fallacy Detective: Thirty-Eight Lessons on How to Recognize Bad Reasoning (Paperback)
I've heard of The Fallacy Detective for years, and it has been on my wish list for awhile. When the opportunity to review it arose, I quickly volunteered. I haven't seen the earlier versions, so this review will not be a comparison of the 3rd edition with previous editions. It will focus solely on the recently released 3rd edition of the book. The cover does state that the new book contains more fallacies and more cartoons, though.

If you're wondering what a fallacy is, the very first sentence of the book defines it as "an error in logic -- a place where someone has made a mistake in his thinking." Sometimes we do this unintentionally, but sometimes these fallacies are used intentionally to mislead consumers and the general public. The ability to recognize fallacies is important.

My first reaction to the book when it arrived was that the cover design is very catchy and pleasing, and the softcover book was well-made. The 9" x 6.5" size is a nice one to hold, larger than a standard paperback, but not as bulky as a full-size text book. The book includes Peanuts, Dilbert, Calvin and Hobbes, and other cartoons. Its design, with the cartoons and short lessons, is appealing to myself and my students.

The book is divided into 38 logic lessons. It begins with an introduction that explains what a fallacy is, then moves into 3 lessons on thinking and listening skills. After that, the fallacy lessons begin: 9 lessons on methods used to "Avoid the Question", 9 lessons on "Making Assumptions", 7 lessons on "Statistical Fallacies", and 10 lessons on "Propaganda". The book concludes with "The Fallacy Detective Game" and the Answer Key to the lessons.

Each lesson begins with a concise and enjoyable description of that fallacy, complete with cartoons to help illustrate the point. Then there are a variety of exercises to help you understand the fallacy and identify it in the world around you. The lessons rely heavily on discussion to help students assimilate the information.

My plans were to use this book with my 12 and 14 year old daughters, doing one lesson together at a time. That backfired when my 14 year old (9th grader) ran off with the book and began to devour it. She was fascinated with learning to identify the fallacies, and quickly read through the book. She then started trying to trick us into using a fallacy in our discussions so she could pounce on it. It didn't work, but it was fun to see her looking for fallacies.

I still plan to continue to go through the book with the girls, one lesson at a time. Although my daughter has enjoyed reading it quickly, I am sure she'll get more out of it when we take it more slowly and discuss the exercises together. Once we've finished the book, we can enjoy "The Fallacy Detective Game" together ... sounds like a good car game for family trips.

It is well worth the $22.00 cost, is completely reusable and non-consumable. It can be used to provide a year long curriculum in logic, covering one fallacy a week and spreading the exercises out over the course of the week. My ideal method would be to read the fallacy lesson together on Monday, discuss a few exercises together, then assign additional exercises to be completed independently. This should also lead to great discussion as we spot fallacies in the world around us.

The Fallacy Detective is an excellent logic book for junior and senior high students. It will give students a foundation in logic that will help them think critically about the information surrounding them in life. It will also give them an advantage in school subjects like essay writing, speech, and debate. Its format is easy to use, enjoyable, and most importantly ... effective in teaching the fallacies.

5.0 out of 5 stars An excellent book!, November 12, 2009
This review is from: The Fallacy Detective: Thirty-Eight Lessons on How to Recognize Bad Reasoning (Paperback)
What a great book for learning logic and critical thinking. While homeschooling, I taught a class at our co-op in "Worldview and Literature" where I (hopefully) led the students to realize all writing is done from a particular worldview and to realize how all our media influences our thinking.

That is one of the reasons this book would be well worth using in your homeschool, your co-op, or even with non-homeschooling families who enjoy discussing such subjects. I read a little of it here and there to Christopher, who said it reminded him of the important subjects he learned in debate at the co-op. This is the perfect book for use in co-op debate and/or critical thinking classes!

Having one child graduate from the University and another going through right now... I can't emphasize enough how important it is for young people to be able to stand firm in their beliefs in today's culture. Not only that, but to communicate their beliefs, challenging wrong teaching, and having the ability to reach the culture with good skills.

The Fallacy Detective is full of stories and cartoons to make (what could be) a challenging subject easy and fun to learn for younger students (age twelve and above) but it is "deep" enough to be used by high school and adult students. It is one of those books that you can use over and over again with multiple age students.
