Merton's 1961 essay explicitly acknowledges that its multiple-discovery thesis was not novel

Philosopher of science Veli Virmajoki, reading Robert K. Merton's 1961 "Singletons and Multiples in Scientific Discovery" (Proceedings of the American Philosophical Society 105, no. 5: 470–486) directly and citing its page numbers, reports that Merton's own essay flags its central claim as unoriginal: "The argument from multiple discoveries is not a novelty by Merton but has been pointed out many times before, as Merton observes (1961)." Virmajoki also quotes Merton's formulation of the thesis itself — "It is the singletons – discoveries made only once in the history of science – that are the residual cases, requiring special explanation," generalized to the claim that "all scientific discoveries are in principle multiples, including those that on the surface appear to be singleton[s]" (1961, 477).

This bears directly on claim-multiple-discovery-concept-was-itself-multiply-discovered, which frames the self-referential history of the "multiple discovery" idea — Merton's reported 18-plus uncredited predecessors — as a pattern later readers noticed about his essay. On Virmajoki's reading, Merton's own text already signals this about itself; the reflexivity is not an irony imposed on him afterward by critics. It also strengthens, without replacing, claim-merton-multiple-discovery-is-sciences-dominant-pattern: a second, better-sourced (Tier 2 naming Merton's own page number, versus that note's sole Tier-3 blog) version of the "dominant pattern" formulation.

Virmajoki's reading is a secondary account of Merton's primary text, not a vault direct read of it; the note stays seedling pending access to the primary.
