This page is a proposed guideline for establishing which non-mainstream "theories" should have articles in Wikipedia. This refers to "theory" in a very broad sense, including (self-described) scientific thories, conspiracy theories, or things which in a stricter sense may be hypotheses, conjectures, or speculations. These guidelines refer specifically to the creation of entire articles about said topics, not to the inclusion of alternative points of view in individual articles. These guidelines do not speak to the content of the articles, which are still completely subject to WP:NPOV and other policies.
Proposed guidelines
- "Mainstream" here refers to ideas which are accepted or at least somewhat discussed as being plausible within major publications (large-circulation newspapers or magazines) or respected and peer-reviewed scientific publications. This should be understood in a commonsense sociological way and not as an attempt to create a rigorous philosophical demarcation between "mainstream" and "non-mainstream", which is likely impossible.
- Any non-mainstream theories should be referenced in at least one major mainstream publication or by another mainstream group. Even a debunking or incredulous reference is fine.
- The discussion of a non-mainstream theory by other non-mainstream groups is not a criteria for notability.
