The subtitle of the book is the Skeptic’s Guide Field Guide to Spotting Fallacies and Deceptive Arguments. The skeptical inquirer, whether a student, an academic or a member of the public, is a person who has the habit of questioning assertions made by others.
This second edition of Humbug! has been expanded and now includes three sections. Part 1 provides a rationale for the book and an introduction to critical thinking, Part 2 provides some simple techniques that are useful in the analysis of arguments and in forming a position, and Part 3 describes and provides examples of common fallacies and flawed arguments.
