Fallacies are defects in an argument - other than false premises - which cause an argument to be invalid, unsound or weak. Fallacies can be separated into two general groups: formal and informal. A formal fallacy is a defect which can be identified merely by looking at the logical structure of an argument rather than any specific statements.
Lesson Summary. A logical fallacy is an argument that appears on the surface to be reasonable but in reality is weak or faulty and misleading. There are a few subcategories of fallacies: the structural fallacy, the verbal fallacy and the material fallacy (the last of which was the focus of this lesson). Logical fallacies are most often accidental or unintentional, based on a misinterpretation of information or the need for more evidence.
