The logical fallacy of accident (also called destroying the exception or a dicto simpliciter ad dictum secundum quid) is a deductive fallacy occurring in statistical syllogisms (an argument based on a generalization) when an exception to a rule of thumb is ignored. It is one of the thirteen fallacies originally identified by Aristotle. The fallacy occurs when one attempts to apply a general rule to an irrelevant situation.
