Wikipedia:Core content 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:

  1. Neutral point of view (WP:NPOV) – All Wikipedia articles and other encyclopedic content must be written from a neutral point of view, representing significant views fairly, proportionately and without bias.
  2. Verifiability (WP:V) – Material challenged or likely to be challenged, and all quotations, must be attributed to a reliable, published source. In Wikipedia, verifiability means that people reading and editing the encyclopedia can check that information comes from a reliable source.
  3. No original research (WP:NOR) – Wikipedia does not publish original thought: all material in Wikipedia must be attributable to a reliable, published source. Articles may not contain any new analysis or synthesis of published material that serves to advance a position not clearly advanced by the sources.

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 The principles upon which these policy statements are based are not superseded by other policies or guidelines, or by editors' consensus.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.
