Economist [[entity-benjamin-f-jones|Benjamin F. Jones]] (Northwestern, Kellogg) argues in "The Burden of Knowledge and the 'Death of the Renaissance Man'" (NBER Working Paper 11360, 2005) that as a field's accumulated knowledge grows, each new innovator must climb further just to reach its working frontier before they can contribute anything new. That rising climb forces one of two adaptations: narrower specialization within a field, or collaboration in teams that pool complementary specialties instead of requiring any one person to master them all. Jones's broader claim is that both adaptations show up empirically across the twentieth century — later ages at first major innovation, and larger inventive/research teams.

He illustrates the mechanism with an invention popular memory credits to a single name: "The microprocessor was one person's inspiration, but several people's invention." Ted Hoff conceived the general-purpose processor architecture; the transistor-level silicon design was executed separately by Federico Faggin. Distinct expertise, one team, one name that survives in the retelling. The vault already holds this exact case in detail, previously unlinked to any team-science framework: [[claim-ted-hoff-widrow-phd-student-architected-intel-4004]].

This is a mechanistic account of *why* research teams grow, distinct from the empirical measurement of *that* they grow — see the companion data at [[claim-wuchty-jones-uzzi-2007-team-size-in-science-grew-1955-2000]]. Together the two supply the missing middle step argued in [[observation-burden-of-knowledge-bridges-population-scaling-and-credit-compression]], which connects this note to the vault's population-scaling cluster ([[observation-population-scaled-improvement-hits-a-sublinear-brake-across-domains]]) and its credit-misattribution cluster ([[claim-credit-detectors-are-themselves-misattributed]]).

Note on authorship: this Jones is Benjamin F. Jones, not Charles I. Jones — co-author of [[claim-bloom-2020-ideas-are-getting-harder-to-find]] — a genuine surname collision between two economists working adjacent territory (team-size economics vs. idea-production economics), confirmed by checking both authors' faculty pages directly.

> [!note] Seek's commentary:
> The line that earns the paper its citation: a name is a summary, and summaries lose to the actual roster the moment anyone checks the acknowledgments. Hoff's architecture and Faggin's silicon aren't one invention wearing two footnotes — they're two inventions wearing one name, and "burden of knowledge" is the first mechanism I've read that explains why this keeps happening, instead of just cataloguing that it does.
