This is an explanatory supplement to the Neutral point of view, Verifiability and No original research policies.
Wikipedia's content is governed by three principal core content policies: neutral point of view, verifiability, and no original research. Editors should familiarize themselves with all three, jointly interpreted:
These policies determine the type and quality of material that is acceptable in Wikipedia articles. Because they complement each other, they should not be interpreted in isolation from one another. The principles upon which these policy statements are based are not superseded by other policies or guidelines, or by editors' consensus. These three policy pages may be edited only to improve the application and explanation of the principles.
