An informal fallacy is an argument whose stated premises fail to support their proposed conclusion. Informal fallacies often come about because of an error in reasoning. The premises are then erroneously linked to the conclusion. In contrast to a formal fallacy, the error has to do with issues of inference because language is used to state the propositions; natural language allows to say more than the symbolism of formal logic can represent.
For the formal concept in philosophy and logic, see formal fallacy. For other uses, see Fallacy (disambiguation). A fallacy is the use of invalid or otherwise faulty reasoning, or wrong moves in the construction of an argument. A fallacious argument may be deceptive by appearing to be better than it really is.
