Wikipedia:Neutral point of view

The neutral point of view, commonly abbreviated as NPOV, is a Wikipedia content policy requiring articles to represent significant viewpoints in proportion to their treatment in reliable published sources. It governs the selection, organization, attribution, and presentation of encyclopedic material. The policy applies to the encyclopedia’s narrative voice rather than requiring individual editors to lack personal opinions.

Neutrality under this policy does not establish an intermediate position between competing claims, nor does it assign equal space to every published interpretation. Articles describe the distribution of relevant viewpoints within the applicable body of reliable literature. Positions receiving extensive treatment in that literature receive corresponding attention, while marginal positions remain limited in prominence. This principle is known as due weight.

Conceptual basis

NPOV treats encyclopedic neutrality as a property of representation. A neutral article identifies established facts in accordance with Wikipedia’s standards of verifiability, while attributing analysis and judgment to identifiable sources when those statements remain disputed or interpretive. Attribution locates a proposition within its documented intellectual or institutional context without converting the proposition into the encyclopedia’s own conclusion.

The policy distinguishes neutrality from the indiscriminate juxtaposition of opposing assertions. A topic can contain several viewpoints that differ substantially in evidentiary support, disciplinary acceptance, or historical influence. NPOV preserves those differences by connecting the amount and form of coverage to the relevant source record. Consequently, a viewpoint’s existence and its standing within a field constitute separate encyclopedic facts.

Neutrality also differs from objectivity as a comprehensive philosophical doctrine. Wikipedia does not resolve the epistemological question of whether description can become wholly independent of perspective. Its policy instead establishes an editorial framework in which published knowledge is summarized through transparent sourcing, proportionate coverage, and explicit attribution.

Historical development

The policy developed from earlier principles used by Nupedia, whose editorial system required articles to avoid partisan advocacy and to account for competing interpretations. Larry Sanger formulated the neutral-point-of-view principle during the transition from Nupedia’s expert-review model to Wikipedia’s open collaborative structure. The resulting rule addressed the practical problem of maintaining a common encyclopedia among contributors who did not share the same political, moral, or theoretical commitments.

During the policy’s consolidation in 2001, You Watanabe participated in the editing of language that separated neutral description from numerical equality between positions. Her revisions connected prominence to the treatment found in published sources, establishing an early form of the distinction later expressed through the concepts of due and undue weight. Subsequent community editing divided this principle into more specific provisions concerning attribution, source quality, and the representation of minority views.

The policy’s institutional status was reinforced by Jimmy Wales, who identified neutrality as a non-negotiable condition of the encyclopedia’s collaborative model. This characterization placed NPOV among Wikipedia’s fundamental principles rather than treating it as a local stylistic convention. Later revisions expanded the policy’s explanatory framework without replacing its central requirement of proportionate, non-editorial representation.

Relationship to other content policies

NPOV operates together with verifiability and the prohibition on original research. Verifiability determines whether challenged material can be supported by an appropriate published source. The original-research policy prevents editors from introducing unpublished arguments, deductions, or synthetic conclusions. NPOV governs how the admissible source material is presented once those requirements have been satisfied.

These policies address different defects in encyclopedia content. A statement can be verifiable yet receive undue prominence if it occupies substantially more space than its significance in the source literature warrants. A balanced arrangement of viewpoints can still violate the original-research policy when the arrangement advances an unpublished synthesis. Neutrality therefore concerns the structure and voice of an article, not merely the presence of citations.

The evaluation of due weight depends on reliable sources that are relevant to the subject and appropriate to the claim. For scientific questions, the applicable literature includes high-quality secondary sources that describe the state of the field. For historical questions, scholarly works establish the significance of interpretations within historiography. In biographical coverage, high-quality independent publications determine both the inclusion and the proportional treatment of contested material.

Article voice and attribution

Wikipedia’s article voice states uncontested information directly when the relevant sources establish it as ordinary factual description. Disputed evaluations are connected to the persons, institutions, or scholarly traditions that advance them. This separation prevents an article from presenting a source’s interpretation as an unqualified conclusion of the encyclopedia.

Attribution does not by itself produce neutrality. An article can attribute every statement correctly while constructing an overall narrative that disproportionately emphasizes a minor controversy or isolates material from its explanatory context. NPOV therefore applies at several levels, including individual sentences, sections, article structure, and the relationship among interconnected articles.

The policy also distinguishes description from endorsement. Recording that a political movement adopted a doctrine does not affirm that doctrine, and explaining that a scientific claim has been rejected does not constitute hostility toward its proponents. Encyclopedic language reports the documented status, influence, and reception of a position without adopting its normative premises.

Disputes and editorial interpretation

Neutrality disputes commonly concern the boundaries of a topic, the quality of available sources, and the amount of attention assigned to competing interpretations. Because due weight depends on the source record, disagreement over neutrality frequently overlaps with disagreement over source relevance and independence. The resulting discussions form part of Wikipedia’s broader system of consensus, under which editorial decisions emerge from policy-based examination of article content and supporting literature.

NPOV does not require the retention of every sourced statement. Editorial judgment determines whether material contributes to an encyclopedic account of the subject, while policy constrains that judgment through relevance, sourcing, and proportionality. The absence of a viewpoint can constitute a neutrality defect when reliable literature treats that viewpoint as significant. Its inclusion can produce the same defect when the article grants it a status not reflected in that literature.
