Poe's law is an Internet adage which states that, without a clear indicator of the author's intent, parodies of extreme views will, to some readers, be indistinguishable from sincere expressions of the parodied views.
"Poe's law" was originally written by Nathan Poe in 2005, in a post on christianforums.com, an Internet forum about Christianity. The post was written in the context of a debate about creationism, where a previous poster had remarked "Good thing you included the winky. Otherwise people might think you are serious". Poe then replied, "Without a winking smiley or other blatant display of humor, it is uttrerly [sic] impossible to parody a Creationist in such a way that someone won't mistake for the genuine article." The original statement of Poe's law referred specifically to creationism, but it has since been generalized to apply to any kind of fundamentalism or extremism.
In part, Poe's post reiterated advice often posted on internet forums, about the need to clearly mark sarcasm and parody (e.g. with a smiling emoticon) to avoid confusion. As early as 1983, Jerry Schwarz, in a post on Usenet, wrote:
Avoid sarcasm and facetious remarks.
Without the voice inflection and body language of personal communication these are easily misinterpreted. A sideways smile, :-), has become widely accepted on the net as an indication that "I'm only kidding". If you submit a satiric item without this symbol, no matter how obvious the satire is to you, do not be surprised if people take it seriously.
