false premise

Unsound starting point

A false premise is a statement assumed to be true that is actually incorrect, used as the basis for an argument or conclusion.

Reasoning built on a false premise may be logically valid yet still reach a wrong conclusion: The argument fails because it rests on a false premise.

The phrase often appears in debates and logical analysis.
