Circular reporting

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 reporting or intelligence-gathering. However, the situation can also be intentionally contrived by the source or reporter as a way of reinforcing the widespread belief in its information.

Circular reporting 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. It is also a problem in journalism and the development of conspiracy theories, in which the primary goal of a source spreading unlikely or hard-to-believe information is to make it appear to be widely known.

The case of the 2002 Niger uranium forgeries was a classic instance of circular reporting by intelligence agencies.

Author Alex Haley grew up hearing the oral history that his family's first ancestor to enter the United States was a young man named Kunta Kinte, who lived near the Kamby Bolongo, or Gambia River, and was kidnapped into slavery when out gathering wood. As an adult, Haley researched his family genealogy for what would become the 1976 novel Roots: The Saga of an American Family, and he traveled to the Gambia in an attempt to confirm the family history of Kinte. Haley told the story of Kinte to a seminar of Gambian tribal experts, who searched for a griot—an oral historian—who might be able to confirm the story. Ultimately, Haley met a man named Kebba Fofana in the town of Juffure who was able to relate a story of Kunta Kinte that was strikingly similar to Haley's lifelong family history, an apparent confirmation that grounded Haley's novel (as well as the landmark 1977 miniseries adapted from the novel). After publication, however, it was discovered that griot oral histories were not reliable for dates before the 19th century, that Fofana was not a true griot, and that Fofana's confirmation of Haley's history was ultimately a retelling of the story Haley himself told Gambian experts.

In 2001, the Niger uranium forgeries, documents initially released by SISMI (the former military intelligence agency of Italy), seemed to depict an attempt made by Saddam Hussein in Iraq to purchase yellowcake uranium powder from Niger during the Iraq disarmament crisis. They were referenced by other intelligence agencies to convince their governments or public that such a purchase had taken place.

In 2004, the Chairman of the US Senate Report on Pre-war Intelligence on Iraq told NBC's Tim Russert that a single informant, 'Curveball' "had really provided 98 percent of the assessment as to whether or not the Iraqis had a biological weapon." This was despite the fact that "nobody inside the U.S. government had ever actually spoken to the informant—except [for a single] Pentagon analyst, who concluded the man was an alcoholic and utterly useless as a source."

In early 2012, a TV Tropes user named Tunafish claimed that a bug existed in Civilization that caused Gandhi to be much more aggressive. Tunafish did not provide any proof. The repetition of this false information led to the "Nuclear Gandhi" internet meme.

In 2018, Shehroze Chaudhry was identified as an active member of the Islamic State who participated in the killing of several individuals, through reporting involving a New York Times podcast, among others. The podcast and other outlets referenced blog posts authored by Chaudhry starting in 2016. The podcast was taken by government officials and others as evidence of the crime; however, the original posts were unverified and later renounced by the author.
