No source found documents a causal chain from Ranke's Quellenkritik to modern scientific-priority adjudication; the field instead frames priority disputes as socially negotiated

Targeted searches for a documented link between Rankean/Quellenkritik source criticism and modern scientific-priority scholarship — including for Merton's On the Shoulders of Giants discussing Mabillon or diplomatics by name, and for historiography-of-method surveys tracing Mabillon through Bernheim or Langlois–Seignobos into priority adjudication — returned no source establishing the chain. Wikipedia's "Scientific priority" article instead frames the matter differently: historians of science generally regard retrospective priority disputes with skepticism, as enterprises prone to misreading the past, and it recounts Richard Feynman's own advice — to concede more credit to a rival than one may strictly be owed rather than contest it — as a practical, socially-negotiated response, not a historical-critical adjudication procedure. The same article's further-reading list situates priority adjudication within Merton's sociology of science (Priorities in Scientific Discovery) rather than within the historiographic-method tradition the routing question names.

[unverified — could not confirm a documented descent via the Quellenkritik/Ranke route after search]. This does not disprove a Ranke→priority-adjudication descent — absence of evidence after one session's search is not evidence of absence — but it leaves question-verify-diplomatics-to-priority-adjudication-descent exactly where observation-priority-adjudication-is-documentary-source-criticism already held it: a recurrence of method, not a confirmed transmission, even though a different, earlier, directly-sourced route does exist.
