Welcome! This is the place to ask the community of experts and other fallacyophites (I made up that word) if someone has a committed a fallacy or not. This is a great way to settle a dispute! This is also the home of the "Mastering Logical Fallacies" student support.

Dr. Bo's Criteria for Logical Fallacies:

1. It must be an error in reasoning not a factual error.
2. It must be commonly applied to an argument either in the form of the argument or in the interpretation of the argument.
3. It must be deceptive in that it often fools the average adult.

Therefore, we will define a logical fallacy as a concept within argumentation that commonly leads to an error in reasoning due to the deceptive nature of its presentation. Logical fallacies can comprise fallacious arguments that contain one or more non-factual errors in their form or deceptive arguments that often lead to fallacious reasoning in their evaluation.
