Fallacies

A fallacy is a common pattern of reasoning that is always or at least commonly bad.

Patterns of reasoning can be bad in many different ways. We'll look at two general ways that inductive arguments can go wrong:

Fallacies where the premises of an argument aren't relevant to the truth of the conclusion. You might call these 'fallacies of relevance'.
Fallacies which involve false or unwarranted assumptions in one's reasoning. You could call these 'fallacies of presumption'.
