[[entity-robert-merton|Robert K. Merton]]'s sociology of science inverts the intuitive picture of
discovery. On his account, "the pattern of independent multiple discoveries in
science is in principle the dominant pattern rather than a subsidiary one" — so
the phenomenon requiring explanation is not why the same thing gets discovered
twice, but why it is ever discovered only *once*. Singletons, on this reading,
are the anomaly; multiples are the rule, because a discovery becomes possible
when the prior state of knowledge makes it "in the air" for anyone positioned to
reach it.

This thesis supplies the general law behind the vault's recurring priority
threads. The [[myth-werbos-invented-backpropagation|Werbos backpropagation
myth]] is precisely a singleton credit imposed on a multiple: the [[entity-automatic-differentiation|reverse mode]]
of differentiation was
[[claim-reverse-mode-multiple-independent-discovery|independently reached at
least five times across five fields]] (Ostrowski, Hachtel, Linnainmaa, Werbos,
[[entity-david-rumelhart|Rumelhart]]–Hinton–Williams), which is Merton's dominant pattern in miniature —
and [[claim-linnainmaa-priority-not-paternity|priority without paternity]] is
the shape multiples take when there is no channel of transmission between them.
Adjudicating such a myth is the source-critical act described at
[[observation-priority-adjudication-is-documentary-source-criticism]].

The thesis has a standing rival in the vault:
[[claim-chandler-simultaneous-discoveries-are-incremental-repackagings|Tertius
Chandler]] holds that most apparent multiples are really shared descent from a
common prior — repackagings, not independent convergence. The [[entity-backpropagation|backprop]] story
sits inside exactly this dispute. Merton's framework also anchors the vault's
wider sociology-of-credit cluster
([[claim-credit-assignment-spans-sociology-and-backprop]],
[[claim-credit-detectors-are-themselves-misattributed]]).

The claim currently rests on a single Tier-3 blog quoting Merton; his 1961
primary has not been read, so the note stays `seedling` — routed to
[[question-verify-merton-multiples-dominant-pattern-and-predecessors]].
