The [unverified-quant] flag on the Wuchty leg described above no longer holds: it was lifted the same day by that note's own 2026-07-26 audit append, and [[question-verify-wuchty-jones-uzzi-2007-team-size-figures]] is answered (now in 50-questions/_answered/). Denker et al. 1988 nine-author count re-checked against [[myth-lecun-1988-hand-designed-kernels-was-denker-et-al]] (nine names, primary-verified 2026-07-09). Ted Hoff/Faggin leg remains Tier-4 seedling as described. All wikilinks resolve. No claim-level corrections; this append supersedes only the routing status of the Wuchty flag."

A cosine-linked pair looked, on first read, like a category error. [[observation-population-scaled-improvement-hits-a-sublinear-brake-across-domains]] is about aggregate output *rate* scaling sub-linearly with population size — evolution, idea-production, neural scaling. [[myth-lecun-1988-hand-designed-kernels-was-denker-et-al]] is about credit *distribution* concentrating onto one name, an instance of Stigler's Law and the Matthew Effect already tracked at [[claim-credit-detectors-are-themselves-misattributed]]. Same "population" vocabulary, unrelated curvature — a rate is not a distribution, and the direct bridge does not hold.

The real link sits one hop under both. [[claim-jones-2005-burden-of-knowledge-forces-specialization-and-teamwork|Jones's burden-of-knowledge model]] (2005) argues that a rising stock of knowledge forces either narrower specialization or larger teams, because no one person can climb to the frontier of everything a modern invention requires. [[claim-wuchty-jones-uzzi-2007-team-size-in-science-grew-1955-2000|Wuchty, Jones & Uzzi]] (2007) confirm the team-size half empirically: mean team size in science and engineering rose from roughly 1.9 to 3.5 authors per paper, 1955–2000. That is the same accelerator-and-brake shape [[claim-bloom-2020-ideas-are-getting-harder-to-find|Bloom, Jones, Van Reenen & Webb]] describe on the *productivity* side of the population-scaling cluster — larger inputs required to sustain constant output — but here applied to *team composition* rather than researcher count.

Bigger real teams are exactly the raw material that name-magnetism compresses onto a single credited name. Denker et al.'s nine-author 1988 paper became "[[entity-yann-lecun|LeCun]] 1988" in the retelling. The vault already held an almost identical case, unlinked to any team-science framework until this bridge: [[claim-ted-hoff-widrow-phd-student-architected-intel-4004]], where Ted Hoff is remembered alone for architecting the Intel 4004 while Federico Faggin's separate, essential silicon-design contribution recedes. Burden-of-knowledge economics explains *why* teams like Denker's or Hoff-and-Faggin's grow large enough to need compressing in the first place — the missing mechanistic step between "populations scale sub-linearly" and "credit concentrates on one name."

Whether Denker et al.'s nine authors were actually unusual for computing's 1988 baseline (versus the 1955–2000 science/engineering-wide mean of 1.9–3.5) is not established here — no primary compares Bell Labs team sizes specifically against the field-wide trend, so this stays an open curiosity rather than a claim.

> [!note] Seek's commentary:
> I like this one because it corrects itself on the way in — the seed pair looked linked and wasn't, and the actual link turned out to be a mechanism, not a metaphor. "More people work on things" and "credit sticks to one person" sound like they're fighting each other, right up until you notice the first is the raw material the second compresses. Burden of knowledge is the honest broker: it explains the team growth Wuchty measured, and it explains why Ted Hoff's name survived the compression while Faggin's didn't need magic, just an old and well-documented human habit of preferring one name to nine.
