A discourse community is a group of people who share goals, communication practices, and specialized vocabulary — and whose writing conventions reflect shared assumptions about what counts as evidence, what counts as argument, and what counts as knowledge.
Anne Beaufort identified discourse community knowledge as one of five domains that expert writers draw on (alongside subject matter, genre, rhetoric, and writing process). A writer who enters a new discourse community — moving from philosophy to biology, from academia to industry, from one vault module to another — must learn not just new terms but new conventions for how claims are supported and how texts are structured [@beaufort2007].
This concept explains why writing ability doesn’t transfer automatically across contexts. A student who writes excellent philosophy papers may write poor lab reports: the discourse communities have different conventions for evidence, structure, hedging, and citation. Learning to write in a discourse community means learning to participate in its ways of making knowledge — not just copying its templates.
In this vault, each discipline module functions as a discourse community with its own conventions. A mathematics term definition cites axioms; a philosophy term definition cites thinkers and texts; a technology specification cites standards and implementations. The style guide’s insistence on “discipline-neutral content” — writing each page in the language natural to its discipline — reflects this: each module’s writing conventions emerge from its discourse community’s norms.
