Empirical research can’t reconcile disputes about core values, but it is very good at addressing questions of fact. Neutral point of view and No original research policies demand that we present the prevailing medical or scientific consensus, which can be found in recent, authoritative review articles or textbooks and some forms of monographs, as Wikipedia:Identifying reliable sources demands. Good and unbiased research, based upon the best and most reputable authoritative sources available, helps prevent NPOV disagreements. Try the library for reputable books and journal articles, and look for the most reliable online resources. If you need help finding high-quality sources for something, ask other editors on the talk page of the article you are working on, or ask at Wikipedia:Reference desk.
- Due and undue weight part of Neutral point of view demands other viewpoint held by an extremely small (or vastly limited) minority does not belong in Wikipedia regardless of whether it is true or not and regardless of whether you can prove it or not, except perhaps in some ancillary article. Keep in mind that, in determining proper weight, we consider a viewpoint's prevalence in reliable sources, not its prevalence among Wikipedia editors or the general public.
- Giving "equal validity" part of Neutral point of view explains the Wikipedia neutrality policy does not state, or imply, that we must "give equal validity" to minority views such as pseudoscience, the claim that the Earth is flat, or the claim that the Apollo moon landings never occurred. If that were the case, the result would be to legitimize and even promote such claims. Policy states that we must not take a stand on these issues as encyclopedia writers; but that does not stop us from describing the majority views as such; from fairly explaining the strong arguments against the pseudoscientific theory; from describing the strong moral repugnance that many people feel toward some morally repugnant views; and so forth.
- Neutrality weights viewpoints in proportion to their prominence. However, when reputable sources contradict one another and are relatively equal in prominence, describe both approaches and work for balance. This involves describing the opposing views clearly, drawing on secondary or tertiary sources that describe the disagreement from a disinterested viewpoint.
