Merton's 1957 paper observes that priority disputes are typically waged by the disputants' partisans, third parties who sometimes act as arbitrators rather than advocates — as Lyell and Hooker did for Darwin and Wallace

Robert K. Merton's 1957 paper "Priorities in Scientific Discovery" observes that priority disputes are characteristically waged not by the discoverers themselves but by their partisans — friends and followers, or more detached scientists who take up a colleague's cause. In a footnote qualifying that pattern (footnote 15, p. 639; confirmed as one contiguous sentence by the 2026-10-11 audit), Merton notes: "Sometimes, of course, they act as judges and arbitrators rather than advocates, as was true of Lyell and Hooker in the episode involving Darwin and Wallace." Rather than pressing one claimant against the other, Charles Lyell and Joseph Dalton Hooker brokered the joint 1858 Linnean Society presentation of Darwin's and Wallace's independently reached theories of natural selection.

This adds the social dynamics of a priority fight to the vault's Merton-1957 cluster, which otherwise documents the institutional machinery — the Newton–Leibniz Royal Society committee (claim-merton-1957-newton-leibniz-committee-textbook-institutional-norm-case) and the general documentary toolkit of sealed dated deposits, journals' received-dates, and a proposed patent-office equivalent (claim-merton-1957-documentary-infrastructure-catalogue-for-priority-norm-enforcement). It is a distinct facet of the same reward-system account (claim-merton-priority-disputes-institutional-norm-enforcement): a disputed priority draws in a whole community because a violated priority norm is felt as a communal wrong, and the community sometimes supplies its own arbitrators rather than only its advocates.

Third-party arbitration is not an alternative to documentary adjudication. In the Darwin–Wallace case the arbitration itself ran on dated documents: the Lyell–Hooker covering letter laid the materials before the Society "Taken in the order of their dates," presenting Darwin's dated 1839/1844 manuscripts and his 1857 letter to Asa Gray as evidence of his earlier date (see commentary). Arbitration and documentary source-criticism coincide here rather than oppose — the same reading the vault reaches from the institutional side at observation-merton-quellenkritik-null-chain-pairing-is-confirmed-bridge-via-1957-primary, where Merton's norm is enforced through dated-document comparison, and the same method-identity named at observation-priority-adjudication-is-documentary-source-criticism.
