Use layered citations to make arguments checkable

The memoir test also explains why academic works sometimes attach two or three citations to one claim. An archival government document anchors the argument in a primary source, while accessible histories let readers check how the author has interpreted that evidence. Multiple references are especially valuable when the conclusion is unusual because they make the evidential chain visible. Such citations let readers test whether the supporting works have been represented accurately. Historians build trust by making their reasoning open to verification.
