The Fallacy Detective
By Nathaniel Bluedorn & Hans
Bluedorn
Thirty-Six Lessons on How to Recognize Bad Reasoning

by Nathaniel Bluedorn and Hans Bluedorn

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

These are fallacies:

“A cloud is 90% water. A watermelon is 90% water. Therefore, since a
plane can fly through a cloud, a plane can fly through a watermelon.�

“This new book, The Fallacy Detective, must do a good job teaching
logic. It has been on the bestseller list for months.�

We wrote this book to meet the needs of Christian parents who want a do-
able text for introducing logic and critical thinking to their children.

Fun to use – not dry like a math textbook.
Self-teaching – not intimidating, starts students with skills they can use
right away.
Each lesson has exercises for students, with an answer key at the back.
Covers logical fallacies and propaganda techniques. We divided the most
common fallacies and propaganda techniques into thirty-six lessons. We
explain how you can spot fallacies, and we give exercises to stretch your
abilities for detecting fallacies.
Geared for ages thirteen and older – we suggest using The Fallacy
Detective before advancing onto more difficult logic programs.
Includes The Fallacy Detective Game, giving you and your friends an
entertaining way to spot and make up your own examples of fallacies.
