Wikipedia:Neutral point of view
|This page in a nutshell: Articles must not take sides, but should explain the sides, fairly and without editorial bias. This applies to both what you say and how you say it.|
All encyclopedic content on Wikipedia must be written from a neutral point of view (NPOV), which means representing fairly, proportionately, and, as far as possible, without editorial bias, all the significant views that have been published by reliable sources on a topic.
NPOV is a fundamental principle of Wikipedia and of other Wikimedia projects. It is also one of Wikipedia's three core content policies; the other two are "Verifiability" and "No original research". These policies jointly determine the type and quality of material acceptable in Wikipedia articles, and because they work in harmony, they should not be interpreted in isolation from one another. Editors are strongly encouraged to familiarize themselves with all three.
