Syllogistic fallacies – logical fallacies that occur in syllogisms. Affirmative conclusion from a negative premise (illicit negative) – a categorical syllogism has a positive conclusion, but at least one negative premise. [11] Fallacy of exclusive premises – a categorical syllogism that is invalid because both of its premises are negative ...
Maarten Boudry [27] and others [28] have argued that formal, deductive fallacies rarely occur in real life and that arguments that would be fallacious in formally deductive terms are not necessarily so when context and prior probabilities are taken into account, thus making the argument defeasible and/or inductive.
For example, "Nobody has ever proved to me there's a God, so I know there is no God". [4] Another version of the appeal to ignorance concludes from the absence of proof against a claim that this claim must be true. Arguments from analogy are also susceptible to fallacies of relevance. An analogy is a comparison between two objects based on ...
The Texas sharpshooter fallacy is an informal fallacy which is committed when differences in data are ignored, but similarities are overemphasized. From this reasoning, a false conclusion is inferred. [1]

In this ungracious move a brash generalization, such as No Scotsmen put sugar on their porridge, when faced with falsifying facts, is transformed while you wait into an impotent tautology: if ostensible Scotsmen put sugar on their porridge, then this is ...
An example: The second grade in Jefferson Elementary eats a lot of ice cream; Carlos is a second-grader in Jefferson Elementary; Therefore, Carlos eats a lot of ice cream; The converse of this fallacy is called fallacy of composition, which arises when one fallaciously attributes a property of some part of a thing to the thing as a whole.
Part of understanding fallacies involves going beyond logic to empirical psychology in order to explain why there is a tendency to commit or fall for the fallacy in question. [ 9 ] [ 1 ] In the case of the false dilemma , the tendency to simplify reality by ordering it through either-or-statements may play an important role.
I tried to remove neglects of probability, however, the article should still include more information on the typical usage of the fallacy in real life. Currently, it consists only of the true but unmotivated statement that "possibly" is not the same as "probably" and that "probably" is not the same as "guaranteed". You can help.
