Outside biology, does 'punctuated equilibrium' have a genuine citation lineage in policy-change theory?

Prompted by the vault's own finding that Chia et al.'s cricket-laws paper uses "punctuated"/"phase transition" language without citing any part of the punctuated-equilibrium literature (claim-cricket-laws-phase-transition-independent-of-punctuated-equilibrium). The question here is whether political science's "punctuated equilibrium theory of policy change" (Baumgartner & Jones) is a different case — a domain that actually engages Eldredge & Gould rather than just wearing the phrase.

Claim: Baumgartner & Jones's punctuated-equilibrium theory of policy change has a genuine, named citation lineage back to Eldredge & Gould (1972) — confirmed by two independent secondary sources, not merely borrowed vocabulary

Claim type: historical/citation-genealogy — load-bearing for this capture, so escalated beyond the Tier 3-4 floor that uncontested historical claims would otherwise clear; corroborated across two independent named-author sources in two different venues (Tier 2-3), though a direct primary-text quote from Baumgartner & Jones's own pen was not obtained (see Claim 3).

Scott E. Robinson, in an encyclopedia entry on "Punctuated Equilibrium" written for the Encyclopedia of Public Administration and Public Policy (Taylor & Francis, 2005), states that Baumgartner and Jones, having observed a mixed pattern of long stable "attention" to policy issues (e.g., nuclear power) occasionally broken by abrupt shifts (e.g., Three Mile Island), reached for a biological model to name and structure that pattern — and names the source directly (see Claim 2 for the exact citation).

Independently, Gordon Shockley (Associate Professor of social entrepreneurship, Arizona State University), in a paper prepared for the Third International Conference on Public Policy Research (Singapore, 2017), states that assessing "PET's development in other fields, most notably in the paleobiology of Stephen J. Gould and Niles Eldredge (Eldredge & Gould, 1972; Stephen Jay Gould, 1992, 2002)" is where "the idea of PET originates," and writes explicitly that Baumgartner and Jones "did not themselves invent its conceptual framework. That distinction, rather, belongs to the paleobiologists Stephen J. Gould and Niles Eldredge."

This is the opposite pattern from Chia et al.: where the cricket-laws paper's "punctuated" is ordinary English used without citation, political science's punctuated-equilibrium-of-policy-change tradition names its biological source directly, in its own secondary literature.

Claim: The citation lineage both secondary sources point to is a specific paper — Eldredge & Gould (1972), "Punctuated equilibria: an alternative to phyletic gradualism," in Models in Paleobiology

Claim type: definitional/bibliographic-identity — Tier 3-4 acceptable for an uncontested citation-identity claim; achieved Tier 3.

Robinson's encyclopedia-entry reference list gives the full citation Baumgartner & Jones drew upon. Shockley's paper independently cites the same underlying work by its standard short form. Both sources agree on the same anchor paper, the same year, and the same pair of authors — the paper the vault's own punctuated-equilibrium cluster already treats as foundational (claim-punctuated-equilibrium-derives-from-mayr-peripatric-speciation).

Separately, Baumgartner's own 550-entry bibliography of policy literature using punctuated-equilibrium theory (Mortensen & Dias, "A bibliography of punctuated equilibrium studies," April 2022, author-hosted) does not itself list Eldredge & Gould 1972 — unsurprising, since that document is scoped to policy-studies applications of PET rather than the foundational biology texts PET draws on; its absence there is not evidence against the lineage, just a mismatch of document scope.

Claim: No freely accessible primary text of Baumgartner & Jones's own writing was located that directly quotes their citation of Eldredge & Gould — the lineage claim rests on Tier 2-3 secondary confirmation, not a primary-text read

Claim type: historical/sourcing-gap — this is the load-bearing claim of the capture, and the floor calls for Tier 1-2 escalation where the underlying claim is this central; despite substantial effort, only a negative result (absence) was obtained at Tier 1.

A search of Frank Baumgartner's own site (fbaum.unc.edu) — the 1991 book proposal, the full introductory chapter to the 2002 companion volume Policy Dynamics ("Positive and Negative Feedback in Politics," read in full, 24 pages), the papers directory, and the PET bibliographies — did not surface a freely available full text of either Agendas and Instability in American Politics (University of Chicago Press, 1993) Chapter 1 ("Punctuated Equilibria in Politics") or the widely-cited True, Jones & Baumgartner chapter "Punctuated-Equilibrium Theory: Explaining Stability and Change in Public Policymaking" (in Sabatier, ed., Theories of the Policy Process, Westview Press, 1999). Both are gated behind their publishers with no author-hosted PDF located.

Notably, the 2002 Policy Dynamics introductory chapter — read in full via extract_pdf — uses "punctuated equilibrium" repeatedly as the organizing concept of the book but does not, across its 24 pages, cite Eldredge or Gould by name; it treats the term as already established from the authors' prior work. This means the Eldredge & Gould citation, if present in the authors' own corpus, most likely lives in the 1993 book or the 1991 Journal of Politics article ("Agenda Dynamics and Policy Subsystems," 53(4):1044–74) rather than in every later restatement — ordinary citation practice (cite the origin once, refer back to one's own prior work thereafter), but it means this capture cannot show the primary-text passage directly.

Further leads

• fbaum.unc.edu's 1991 book proposal for what became Agendas and Instability (then titled "The Politics of Disequilibrium") lists its Chapter 1 as "Politics without Equilibrium" and uses the word "disequilibrium" rather than "punctuated equilibrium" throughout — suggesting the explicit biological framing/naming entered sometime between the 1991 proposal and 1993 publication. Source: https://fbaum.unc.edu/books/agendas/Baumgartner_Agendas_and_Instability_proposal.pdf (Tier 1, author-hosted).
• Eissler, Russell & Jones (2016), "The Transformation of Ideas: The Origin and Evolution of Punctuated Equilibrium Theory" (in Peters & Zittoun, eds., Contemporary Approaches to Public Policy, Palgrave Macmillan, 95–112) — co-authored by Bryan D. Jones himself, this chapter is squarely about PET's origin and would be the most direct source to chase next for a primary-pen confirmation; only its abstract page (scholars.uky.edu) was checked this session, which did not mention Eldredge or Gould within the abstract alone.
• Shockley's paper also quotes Gould & Eldredge's own 1993 retrospective directly — a "novel interpretation for the oldest and most robust of paleontological observations" (Gould & Eldredge, 1993, p. 223) — a lead toward the biology side of this exchange if the vault wants it.
• Per Shockley's footnote, other social-science fields independently discovered similar punctuational patterns around the same time as Baumgartner & Jones: Burnham (1991) on electoral realignment, Kelly (1994), Schubert (1992), and Tushman, Newman & Romanelli (1986) — the last already partly covered by the vault's organizational-theory cluster (claim-gersick-1991-punctuated-equilibrium-deep-structure).
• The Robinson encyclopedia entry also documents True, Jones & Baumgartner's demonstration that U.S. federal budget changes follow a leptokurtic ("punctuated") distribution — a quantitative claim not pursued here since it would need the primary budgetary-data paper, not the encyclopedia summary.

Entity candidates

• Niles Eldredge — person — co-originator (with Gould) of the 1972 paper both secondary sources name as the direct source Baumgartner & Jones drew on; the foundational figure this entire lineage claim rests on, and the one most likely to be under-flagged relative to Baumgartner & Jones themselves.
• Stephen Jay Gould — person — co-originator of the 1972 punctuated-equilibria paper; already has vault presence via entity-punctuated-equilibrium, flagged again here as the figure the policy-theory lineage measures itself against.
• Frank R. Baumgartner — person — co-originator of punctuated-equilibrium theory of policy change; maintains the primary web archive (fbaum.unc.edu) this capture drew most of its Tier 1 material from.
• Bryan D. Jones — person — co-originator of punctuated-equilibrium theory of policy change; co-author of the 2016 "Transformation of Ideas" retrospective chapter on PET's own origin, the most promising lead for a direct primary-text confirmation.
• Scott E. Robinson — person — author of the 2005 "Punctuated Equilibrium" encyclopedia entry that supplied the explicit Eldredge & Gould citation used in Claims 1 and 2.
• Gordon Shockley — person — author of the 2017 IPPA conference paper independently confirming the Eldredge & Gould lineage from a different venue and angle.
• Peter B. Mortensen — person — co-compiler (with Megan Dias) of the 2022 550-entry PET policy-studies bibliography.
• Agendas and Instability in American Politics (1993) — document — the founding book of policy punctuated-equilibrium theory; its own text (not located in full here) is the single most direct source that could resolve Claim 3.
