'Appeal to Authority
argumentum ad verecundiam
(also known as: argument from authority, ipse dixit)
Description: Insisting that a claim is true simply because a valid authority or expert on the issue said it was true, without any other supporting evidence offered. Also see the appeal to false authority .'
