Fun with Fallacies

Funny articles about fallacies:

Online Article


By Bradley Dowden. An article from the Internet Encyclopedia of Philosophy, written by one of the two editors of that reference work. Consists of a short introductory discussion of the scholarly controversies over fallacies, followed by a long list of named fallacies. There are 164 names of fallacies, though many of the fallacies have multiple names. I count 103 fallacies with substantive entries, though necessarily each entry is brief since the entire article is one long webpage! Unfortunately, the examples given are either short cooked-up ones, or the typical textbook chestnuts. If you can't find a fallacy listed in the Fallacy Files, this would be the most likely place to find a short but sound explanation of it on the web.

Logic Basics: Understanding Arguments

By Gary Curtis. This course consists of ten short lessons delivered by email daily by a company called Highbrow. It's a very brief introduction to the fundamental concepts of logic needed to analyze and evaluate reasoning―and, I might add, to understand fallacies. It's a Premium course, which means it's not free, but you can try out Highbrow's Premium service for a month for free, and the course only takes ten days!


Decision Academy

Mini-courses are short, online courses. The Clearer Thinking organization's Decision Academy offers free mini-courses on "Rhetorical Fallacies", "Probabilistic Fallacies", "The Planning Fallacy"―which I don't think is a logical fallacy―and "The Sunk Cost Fallacy"―which I'm often asked about―and some related ones on improving decision-making.
