Godwin's law

Godwin's Law (also known as Godwin's Rule of Nazi Analogies) is an adage formulated by Mike Godwin in 1990. The law states:

"As a Usenet discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one."

Godwin's Law is often cited in online discussions as a caution against the use of inflammatory rhetoric or exaggerated comparisons, and is often conflated with fallacious arguments of the reductio ad Hitlerum form.

The rule does not make any statement whether any particular reference or comparison to Hitler or the Nazis might be appropriate, but only asserts that one arising is increasingly probable. It is precisely because such a comparison or reference may sometimes be appropriate, Godwin has argued that overuse of Nazi and Hitler comparisons should be avoided, because it robs the valid comparisons of their impact. Although in one of its early forms Godwin's Law referred specifically to Usenet newsgroup discussions, the law is now applied to any threaded online discussion: electronic mailing lists, message boards, chat rooms, and more recently blog comment threads and wiki talk pages.

Godwin's law is a specific example of a more general principle that also appears to be true.

"As a Usenet discussion grows longer, the probability of any comparison of any given group to another approaches one."

This law, and Godwin's Law, is supported rationally by acceptance of the fact that, the longer a conversation takes place, the more likely any given idea is to be brought up.

History

Godwin has stated that he introduced Godwin's Law in 1990 as an experiment in memetics.

Linking by implication the fallacy of reductio ad Hitlerum to online discussion length had been done prior to 1990 by a poster named Richard Sexton in 1989: "You can tell when a USENET discussion is getting old when one of the participents [sic] drags out Hitler and the Nazis." Godwin's Law does not, however, claim to articulate a fallacy; it is instead framed as a memetic tool to reduce the incidence of inappropriate hyperbolic comparisons. It has not been established whether Sexton's quip had any influence on Godwin's law, though Sexton has stated that Godwin has acknowledged that he borrowed the idea from Sexton and named it.

Corollaries and usage

There are many corollaries to Godwin's law, some considered more canonical (by being adopted by Godwin himself) than others invented later. For example, there is a tradition in many newsgroups and other Internet discussion forums that once such a comparison is made, the thread is finished and whoever mentioned the Nazis has automatically "lost" whatever debate was in progress. This principle is itself frequently referred to as Godwin's Law. It is considered poor form to raise such a comparison arbitrarily with the motive of ending the thread. There is a widely recognized codicil that any such ulterior-motive invocation of Godwin's law will be unsuccessful (this is sometimes referred to as "Quirk's Exception").

Godwin's Law applies especially to inappropriate, inordinate, or hyperbolic comparisons of other situations (or one's opponent) with Hitler or Nazis or their actions. It does not apply to discussions directly addressing genocide, propaganda, or other mainstays of the Nazi regime. Whether it applies to humorous use or references to oneself is open to interpretation, because although mentioning and trivializing Nazism in an online discussion, this would not be a fallacious attack against a debate opponent.

However, Godwin's Law itself can be abused, as a distraction or diversion, that fallaciously miscasts an opponent's argument as hyperbole, especially if the comparisons made by the argument are actually appropriate. A 2005 Reason magazine article argued that Godwin's Law is often misused to ridicule even valid comparisons. In fact Godwin's law itself has been compared to Hitler's use of fiery rhetoric to destroy the arguments and comparisons of his debaters rather than actually disproving the argument or comparison.

In popular culture

While Godwin's Law is best known in Usenet, it has clearly spread to other forms of online communication. In 2007, Slashdot noted that Godwin's law affected an ongoing, highly public dispute between Linux founder Linus Torvalds and the GNOME project. A May 2007 issue of Randall Munroe's webcomic xkcd anachronistically portrays Allied officers trying to discuss Axis military tactics, but being interrupted by Godwin's Law. Similarly, a November 2007 issue of Jeph Jacques's webcomic Questionable Content, entitled "Godwin Wars", referenced (and contrasted) Godwin's law and the reductio ad Hitlerum. Such appearances, without explanatory material, may suggest that it is increasingly assumed that web users are generally already familiar with the adage. In its October 2007 issue and on its website, Wired published a "Geekipedia" piece that includes an entry for "Godwin's law" among "people, place, ideas, and trends you need to know now".

The concept appears to have entered the public consciousness more broadly, as well. In 2005, the aphorism was the subject of a question in the British television quiz show University Challenge. By 2007, The Economist had declared that "a good rule in most discussions is that the first person to call the other a Nazi automatically loses the argument." And in October 2007, the "Last Page" columnist in The Smithsonian stated that when an adversary uses an inappropriate Hitler or Nazi comparison, "you have only to say 'Godwin's Law' and a trapdoor falls open, plunging your rival into a pool of hungry crocodiles."
