Citogenesis
Where Citations Come From: Citogenesis Step #1 Through a convoluted process, a user's brain generates facts. These are typed into Wikipedia. [Hairy sits at a desk, typing on a laptop.] Hairy: (typing) The "scroll lock" key was was designed by future Energy Secretary Steven Chu in a college project.
Step #2 A rushed writer checks Wikipedia for a summary of their subject. [Ponytail sits at a desk, typing on a desktop.] Ponytail: (typing) US Energy Secretary Steven Chu, (Nobel Prizewinner and creator of the ubiquitous "scroll lock" key) testified before Congress today...
Step #3 Surprised readers check Wikipedia, see the claim, and flag it for review. A passing editor finds the piece and adds it as a citation. [Cueball sits on a couch with a laptop in his lap, typing.] Cueball: Google is your friend, people. (typing) <ref>{{cite web|url=
Step #4 Now that other writers have a real source, they repeat the fact. [A flow chart, with "Wikipedia citation" in the center. The word "Wikipedia" is in black, the word "citations" is white with a red background. [A black arrow leads from "brain" to "Wikipedia."] [A black arrow labeled "words" leads from "Wikipedia" to "careless writers," and a red arrow labeled "citations" leads back to "Wikipedia citations."] [A black & red arrow leads from "Wikipedia" to "cited facts" which leads to "slightly more careful writers," which leads to "more citations," which leads back to :"Wikipedia" (all black & red arrows).] References proliferate, completing the citogenesis process.

This comic is calling into question the reliability of Wikipedia . This is a favorite pastime of librarians, teachers, and professional researchers, and not usually one of Randall 's. Wikipedia is a free and freely editable encyclopedia that aims to become a comprehensive, neutral compilation of verifiable and established facts .  Wikipedia aims to provide only facts backed by reliable sources . However, this comic strip details a process in which Wikipedia can not only spread misinformation but make said misinformation seem reliable through a process of "circular reporting".
The title of the comic is a play on the word cytogenesis . Cytogenesis is the formation of cells and their development. Citogenesis , on the other hand, is a portmanteau of 'Citation' and 'Genesis'. A Citation is a reference to a source, used to back up a specific claim, and genesis means the origin of something.  By extension, citogenesis is the creation of text in a reliable source that can be cited to back up a claim.
In the process described here, someone adds an untrue claim to an article in Wikipedia. A writer of some supposedly "reliable source" checks Wikipedia for information, and blindly relies on it, without checking for proper sources - the comic uses rushed writers, such as those responsible for news stories, as an example of someone who may do this. Eventually, someone notices the claim in the reliable source and cites it in the Wikipedia article. The citation now gives the claim credence, as readers don't realize that the official source was based on the Wikipedia article. Thanks to this citation, other reporters, slightly more cautious than the first, consider this bit of information to be reliable and then cite it in articles of their own. Those articles then get cited in Wikipedia, making the claim seem more reliable, encouraging even more reporters to believe it and repeat the claim. Eventually, a long list of citations is available, giving an impression of consensus, even though all of it originated with a single article, which was based on an uncited Wikipedia edit.
Four years before, Randall commented on Wikipedia about that process happening to him (on a minor detail), which probably indicates the inception of this comic:
In turn, Randall originated the untrue assertion in this comic that Steven Chu , a physicist, and at the time of the strip the U.S. Secretary of Energy, invented the Scroll lock key, a common button on computer keyboards. Since most people are aware of the scroll lock key but know little about its function or origins, this false information would make for an interesting piece of trivia that would likely spread very quickly.
Following this comic, the actual Scroll Lock and Steven Chu articles were both vandalized by "helpful" editors trying to project Randall's reality on Wikipedia. As of May 2022, the Wikipedia article on Citogenesis redirects to the " Circular reporting on Wikipedia " section on the article " Circular reporting ". The section credits the term "citogenesis" to Randall Munroe, with a citation linking to this comic. To make matters even more surreal, a Wikipedia editor once flagged the link to this xkcd comic as "Dubious - The material near this tag is possibly inaccurate or non-factual."!
We haven't seen a book like the one Randall describes in the title text.  But one example of the misuse of Wikipedia by "reliable sources" concerns the former German minister Karl-Theodor zu Guttenberg . His complete name contains fifteen names/words and reads: Karl-Theodor Maria Nikolaus Johann Jacob Philipp Franz Joseph Sylvester Freiherr von und zu Guttenberg. An anonymous user added one more ("Wilhelm") to the German Wikipedia, just the evening before Karl-Theodor zu Guttenberg was presented as the new Federal Minister of Economics and Technology on February 10, 2009. The next day many major German newspapers published this wrong name ( translation of bildblog.de ).
