Wikipedia:Wikipedia is a mainstream encyclopedia

Wikipedia is a mainstream encyclopedia. This means that writers and editors on Wikipedia should strive for articles that would be appreciated as being of the highest quality by a consensus of experts. To accomplish this goal, reliable sources need to be used to verify content. Beyond this, it is also necessary that subjects be handled as they are realized in reliable sources.

Wikipedia is neutral, which means it does not take sides in any dispute. If the preponderance of the best sources indicate that a subject has many equally valid sides, then Wikipedia gives equal space to the description of all sides. However, the best sources may indicate that a subject does not have equally valid sides. This is why Wikipedia gives the most space and prominence to descriptions of a subject that conform to the expert understanding while marginalizing in space and prominence the minority understanding. To do otherwise would create an encyclopedia that experts would not accept as being of the highest quality.

Wikipedia never endorses the expert understanding of a subject; it merely pays the most attention to it. Articles in Wikipedia maintain a neutral, dispassionate tone with regards to the subject, never indicating a preference for or against the perspective being examined.

Every statement made in Wikipedia can be reliably sourced as being disputed by somebody somewhere. This fact is irrelevant to our task at writing a mainstream encyclopedia, and should not be used as justification to create an article that differs from that of a mainstream encyclopedia. Unless the dispute is verifiably acknowledged to exist in high-quality sources, it does not belong in Wikipedia.

Is this situation fair? Perhaps not. But it is the situation we must tolerate if we are going to take Wikipedia being a mainstream encyclopedia seriously.
