|This page in a nutshell: A term with many related meanings should be presented as an article on the broadest understanding of the term, rather than as a disambiguation page merely listing variations on that meaning.|
A broad-concept article is an article that addresses a concept that may be difficult to write about because it is abstract, or because it covers the sometimes-amorphous relationship between a wide range of related concepts. Due to the difficulty of explaining this relationship (and the comparative ease of merely listing articles to which the title relates), ors often create disambiguation pages for such titles, even though there is an unambiguous meaning that can be discerned from the relationship between the listed topics.
However, if the primary meaning of a term proposed for disambiguation is a broad concept or type of thing that is capable of being described in an article, and a substantial portion of the links asserted to be ambiguous are instances or examples of that concept or type, then the page located at that title should be an article describing it, and not a disambiguation page. Where the primary topic of a term is a general topic that can be divided into subtopics, such as chronologically (e.g., History of France) or geographically (e.g., Rugby union in the British Isles), the unqualified title should contain an article about the general topic rather than a disambiguation page.
A disambiguation page should not be created just because it is difficult to write an article on a topic that is broad, vague, abstract, or highly conceptual. Where there are additional meanings that are not instances or examples of a "Foo" primary concept or type, those should be included on a "Foo (disambiguation)" page.
There are some common tests that can be used to determine whether an article can potentially be considered a broad concept article. One of these is "expert" test: could a person reasonably represent themselves as an expert in [name of page], without having to be an expert in multiple fields of knowledge (i.e. without having degrees from different departments in the typical university)? For example, although there are many species of tuna that are called "bluefin tuna" an icthyologist could be an expert in "bluefin tuna" without needing to specify a particular species. Compare that to a person claiming to be a "Mercury" expert, or a "battery" expert. The expert on "Mercury" would need to have both Roman mythology and astronomy in their knowledge base, along with chemistry. The expert on "battery" would need both chemical engineering and legal training, as well as some military history and (depending how significant the subtopic was considered) baseball.
In writing articles on these subjects, it is useful to directly address the scope of the term, and the history of how the concept has developed. Each of the examples of the concept or type of thing should be included at some point in the article, possibly in a list, so that no information is lost from what would have been presented in the disambiguation page format. Consider using summary style to incorporate information about the subtopics into the main article.
