Wikipedia:List of citogenesis incidents

Randall Munroe in his comic XKCD coined the term of Citogenesis to describe the creation of "reliable" sources through Circular reporting. Wikipedia has been a source of much of this citogenesis over the years, and this list is intended to capture all such instances. It is a superset of the list provided at Circular reporting because not all incidents in this list have been reported by the media and thus some of them are based on original research by editors here.
