Logical Fallacy Handbook

by Stephanie Simoes

Logical fallacies are flaws in reasoning. They are often called informal fallacies. Unlike formal fallacies, which always break a rule of logic, informal fallacies are context-dependent: the same argument can be fine in one situation and faulty in another.

The first 10 fallacies in this handbook are covered in Fallacy Detectors, so it is especially useful for parents and teachers who have purchased the course.

Recommended for teens and adults.
