Circular reporting


Circular reporting, false confirmation, or citogenesis is a situation in source criticism where a piece of information appears to come from multiple independent sources, but in reality comes from only one source. In many cases, the problem happens mistakenly through sloppy intelligence-gathering practices. However, at other times the situation can be intentionally contrived by the original source as a way of reinforcing the widespread belief in its information.
This problem occurs in a variety of fields, including intelligence gathering, journalism, and scholarly research. It is of particular concern in military intelligence because the original source has a higher likelihood of wanting to pass on misinformation, and because the chain of reporting is more prone to being obscured. The case of the 2002 Niger uranium forgeries was a classic instance of circular reporting by intelligence agencies.

Examples involving Wikipedia

is sometimes criticized for being used as a source of circular reporting. Wikipedia advises researchers and journalists to, and instead focus on verifiable information found in an article's cited references.
In the following examples, false claims were propagated on Wikipedia and in news sources because of circular reporting. Randall Munroe, in his comic xkcd, called this phenomenon citogenesis.
