First paragraph: "The Journal of Criminal Justice has been on a roll. Once considered a somewhat middling publication — not in the same league as top journals like Criminology and Justice Quarterly — it is now ranked No. 1 in the field according to its impact factor, which measures the average number of citations a journal receives and is meant to indicate which titles are generating the most..." It sounds like the tl;dr is: the incentives created by how 'impact factor' is measured caused the journal to game the system by citing itself ad nauseum.
