The Tuttle Twins Guide to Logical Fallacies

by Connor Boyack, Elijah Stanfield (Illustrator)

In a society where countless ideas are being shared, debated, and analyzed, it’s more important than ever to sift out the good ones from among the bad ones. And when people you respect and trust use arguments that sound persuasive, how can you determine if they are correct?

One of the most commonly used methods of spreading misinformation is the use of a logical fallacy—a bad argument that makes something seem truthful that actually might not be. These types of arguments are used repeatedly, and there are many different types.

Fortunately, these logical fallacies can be learned, so they can be avoided. Armed with this information, you’ll be equipped to understand when people are sharing an idea that is wrong or making a claim that isn’t true. You’ll become an expert debater by being able to point out a flaw in an opponent’s argument.

That makes this book dangerous—a guidebook for teenagers and young adults who want to explore the ins and outs of how to win arguments and point out problems in others’ ideas. Use this book wisely!

Reviews

This book was very thorough yet incredibly understandable. I'm really glad I picked it up because I've been wanting to learn about logic for a while, but it had seemed rather complicated until now. The author presents each fallacy very well with clear examples and explanations. Even though this book is likely for middle schoolers, I think high schoolers would understand it more. I definitely recommend.

I love the tuttle twins and I’ll be going through this with my kids.

It’s a reference book on an essential topic. The vast majority of dialogue on all platforms is nonsense, this book will help kids spot it and deal with it.

[Adam Bloch]

Good guide to logical fallacies. I'm going to make my kids read a book on logical fallacies, and while this one is fine I think I like another choice more.

[Sandy]

My attempt to read nonfiction (I tried several grown up nonfiction books but couldn't get through more than a couple chapters so I am resorting to middle grade nonfiction).

Obviously biased examples, but overall I learned a lot about establishing a well researched argument and avoiding Logical fallacies that do nothing to back your claim.
I truly wish those who were running for government positions would be well versed in and avoid using these techniques as it would be much easier to understand what the candidates actually stood for.

[Meg]

Sauna book- like the now-obsolete bathroom readers, I need something short, interesting, and capable of being read over many sessions to read while in the sauna (that won’t melt in the heat, like the phones that have replaced bathroom readers). This book fit the bill perfectly. Refreshed my knowledge of logical fallacies and will help me explain them to my kids using scenarios they will understand.

[Stephanie]

I got about half way through reading this out loud to my girls. I wanted to have a little bit of a discussion about logical fallacies and critical thinking. It is written in short little chapters with some cartoons and such. It was perfect for what I wanted to accomplish. I told my girls that they could finish it if they wanted to. But I feel like what we did read served it’s purpose for the discussion I wanted to have with them.

[Melody]

This presented logical fallacies in a way that was fairly engaging and easy to follow. It gave examples and explained how to identify fallacies and emphasized that the point of identifying fallacies is to be able to stop them from interrupting the exchange of ideas. I don't think I completely agreed with everything in it, but, overall, it was a useful tool.

[Nikki]

Simple and quick read laying out pitfalls of arguments/debates and how to spot loggical fallicies; great for young HSers who want to question everything in a smart way. Easy to start applying what you have learned just by analyzing modern day politicians and media reports (unfortunately!)

[Lila Mable]

Conner Boyack did an excellent job teaching what the common debating fallacies are, how to politely combat them, and how to avoid them in your own argument. He got his points across well through funny little comics and big real world examples. I feel inspired to go practice my debate skills!

[JL Salty]

rating: g no profanity, sex or violence.
recommend: 4-6th logic instruction.
diversity: includes a healthy dose of Bible, mentions of God.

VERY conservative book. When examples of LACK of logic are given, they tend to be NON-conservative ideas. There is a definite bias / political bent.

[Chappyfamily]

A great introduction to fallacies and teaching your kids how to find the truth.

shelving this til i get back to it

[Cassie Coy]

This has great information younger teens about different styles of communication during a debate and different ways someone might approach topics, such as politics.

[Sarah]

Great reference resource for those starting out in the fallacies research, or for middle school and up.
The examples in each chapter really helped solidify the concepts in my head.

[Kiah Kinnaman]

This book was fascinating!
