The courtier's reply is a type of informal fallacy, coined by American biologist PZ Myers, in which a respondent to criticism claims that the critic lacks sufficient knowledge, credentials, or training to pose any sort of criticism whatsoever. It may be considered an inverted form of argument from authority, where a person without authority disagreeing with authority is presumed incorrect prima facie. A key element of a courtier's reply, which distinguishes it from an otherwise valid response that incidentally points out the critic's lack of established authority on the topic, is that the respondent never shows how the work of these overlooked experts invalidates the arguments that were advanced by the critic. Critics of the idea that the courtier's reply is a real fallacy have called it the "Myers shuffle", implying calling someone out for an alleged courtier's reply is a kind of rhetorical dodge or trick. Usage history American biologist and academic PZ Myers coined the term "courtier's reply" in a December 2006 entry on his blog, Pharyngula. Myers was reacting to some of the criticism leveled at the 2006 book The God Delusion, in which author Richard Dawkins argued against the existence of a supernatural creator. Critics argued that Dawkins' lack of qualifications in philosophy or theology called into question a number of his arguments. Myers responded to this criticism by making an analogy, comparing Dawkins to the boy at the end of the fable The Emperor's New Clothes, who is the only reasonable voice that recognizes the Emperor is naked. Myers satirized the aforementioned critics as follows: I have considered the impudent accusations of Mr Dawkins with exasperation at his lack of serious scholarship. He has apparently not read the detailed discourses of Count Roderigo of Seville on the exquisite and exotic leathers of the Emperor's boots, nor does he give a moment's consideration to Bellini's masterwork, On the Luminescence of the Emperor's Feathered Hat. We have entire schools dedicated to writing learned treatises on the beauty of the Emperor's raiment, and every major newspaper runs a section dedicated to imperial fashion; Dawkins cavalierly dismisses them all. He even laughs at the highly popular and most persuasive arguments of his fellow countryman, Lord D. T. Mawkscribbler, who famously pointed out that the Emperor would not wear common cotton, nor uncomfortable polyester, but must, I say must wear undergarments of the finest silk. Dawkins arrogantly ignores all these
