Wikipedia 'Neutral Point of View' Citation Source Drift
This page tracks how Wikipedia’s ‘Neutral Point of View’ (NPOV) policy is affected by citation decay. When claims rely on external sources, those links can break or domains can change, leaving evidence unsupported. We measure the 404 rate, domain change rate, and how quickly citations decay over time. The data comes from analysing NPOV-tagged claims across Wikipedia articles, highlighting how often evidence disappears and how fast this happens. Understanding this drift helps editors maintain reliable sourcing and shows where Wikipedia’s citation infrastructure needs attention.
