Circular reporting or false confirmation 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.
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.
Wikipedia and The Northern Echo: In January 2014 a statement was anonymously added to the Wikipedia page on UK comedian/broadcaster Dave Gorman stating that "he had taken a career break for a sponsored hitch-hike around the Pacific Rim countries". When this was questioned, an article published at a later date (September 2014) in The Northern Echo, a daily regional newspaper in North East England was cited as evidence. The falsity of the original claim was confirmed by Gorman in an episode of his UK TV show Modern Life Is Goodish (first broadcast 22 November 2016).

This became a classic case of circular reporting," said a U.S. intelligence official who spoke on condition of anonymity because he is not authorized to talk to reporters.
