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!
