Logical Fallacies are faulty arguments, that is: arguments that might seem valid on the surface, but actually violate the rules of logic; they can arise spontaneosly by mistake, bias or incompetence, but can also be used intentionally by dishonest arguers for the purpose of deceiving the audience.
This page includes a list of universally recognized fallacies, but also introduces new ones that, though not officially recognized, still violate universally accepted rules of logic and therefore can still be unequivocably classified as fallacies.
It is important to notice that many fallacies are not defined by their mere form, but also by their context: arguments that might be correct in a specific context might become a fallacy in another, but also the other way around; for this reason many entries also include a specific disclaimer in order to educate the reader to discriminate between real fallacies and false ones, since a false accusation of a fallacy is a fallacy in itself.
