Beta Testers Needed for The Fallacy Detective and The Thinking Toolbox

For those who have been asking for a test companion for The Thinking Toolbox, all can breathe a sigh of relief and exclaim, “finally!” Hans Bluedorn, one of the co-authors of The Thinking Toolbox and The Fallacy Detective book series announced an updated Fallacy test and a new Toolbox test are now available in beta versions. The authors need people to review and provide feedback on both tests as they prepare the final versions for publications.

“Over the years, we have had many requests for a test for The Thinking Toolbox and are finally getting around to making one. The Fallacy Detective test is also being updated a little bit,” said Hans Bluedorn, who notes both tests are “fairly rough drafts.” “I want to see how the students do on the test and then make any needed changes.”

If you homeschool, The Fallacy Detective and The Thinking Toolbox books have probably come across your radar at one time or another. Both books teach logic and critical thinking skills. The Fallacy Detective includes 38 fallacies that help students easily identify bad reasoning. The Thinking Toolbox includes 35 lessons that help readers build their reasoning skills to improve the way they process information.

“We have been working on revising the final test for The Fallacy Detective. We are also creating a final test for The Thinking Toolbox. We will combine both tests into a single PDF for teachers to use after each book is completed,” said Hans, who hopes both tests become valuable resources for parents and teachers using the book series. “They can test students of The Thinking Toolbox [and The Fallacy Detective] to see if they have been paying attention in class!” 

Hans noted testers can be anyone who has gone through The Fallacy Detective or The Thinking Toolbox. Some of the feedback he is seeking is:

• Which questions were too hard?
• Which questions were too easy?
• Which questions didn’t make sense?
• Which answers did the students disagree with?
• How was scoring of the test?
• Were some of the answers too vague for accurate scoring?
• How would you improve these tests?
• Note any typos or errors you found.

Answers to those questions as well as any other information you think will improve the final versions of the tests will be helpful. If you would like to be a beta tester, you may access the tests here.

The final versions are expected to be published summer 2026.
