Help:方針與指引簡介/2
維基百科是一部百科全書，而我們社群正不斷追求維基百科的準確性。維基百科的條目應當中立，並僅能包含已有可靠來源的可查證資訊與見解。

中立觀點（或簡稱NPOV）意思是條目內容必需以客觀無偏見的觀點撰寫而成，並只能包含事實與他人的顯著觀點。Encyclopedias are inherently written in this way as the truth is often subjective, and it would make no sense to have an article that favored a particular viewpoint. This also helps prevent articles from becoming mere advertisements or propaganda by vested parties. |
|
Verifiability means that articles should only contain material that has been published by reliable sources. All content should ideally be supported by a reliable source, but content that is controversial or likely to be challenged will definitely require them! Unsourced material may be removed at any time and it is the obligation for the editor adding material to provide a reliable source. |
|
No original research means that articles may not contain previously unpublished arguments, concepts, data, opinions, or theories. This includes any new analysis or synthesis of these facts. Basically, Wikipedia is a record of human knowledge, viewpoints, and summaries that already exist and are expressed elsewhere. |
