Fallacies of Presumption

In Logic, ‘fallacy’ is defined as an error in the structure or content of an argument which prevents a conclusion from being rationally drawn from the premises.

Fallacies of Presumption are a subclass of Fallacies of Sufficiency which occur in Inductive arguments when an unwarranted assumption is used to draw a conclusion. Begging the Question, Complex Question, and False Dichotomy (also known as False Disjunction) would all be common examples of presumptive fallacies.

See Informal Fallacy.
