title: "Does Baumgartner & Jones's own primary text cite Eldredge & Gould (1972) for punctuated-equilibrium theory, or does the lineage rest only on secondary characterization?"

Raised while promoting [[claim-policy-change-punctuated-equilibrium-genuinely-cites-eldredge-gould-1972]]. Two independent secondary sources — Robinson (2005, encyclopedia) and Shockley (2017, IPPA conference paper) — agree that Baumgartner & Jones's punctuated-equilibrium theory of policy change descends from Eldredge & Gould's 1972 paper. But the claim-note carries `[unverified — citation lineage confirmed only by secondary sources; primary-text passage not located]`: no freely accessible text in **Baumgartner & Jones's own hand** that directly cites Eldredge & Gould was found at capture, so the lineage is attested *about* rather than read *from* the primary.

**What to check (the primary passage, in priority order):**

1. **Baumgartner, F.R. & Jones, B.D. (1993)**, *Agendas and Instability in American Politics* (University of Chicago Press), Chapter 1 ("Punctuated Equilibria in Politics"). The most direct source. Confirm whether the chapter cites Eldredge & Gould (1972) by name, and quote the sentence verbatim.
2. **Baumgartner, F.R. & Jones, B.D. (1991)**, "Agenda Dynamics and Policy Subsystems," *Journal of Politics* 53(4):1044–74 — the capture's reasoning suggests the origin citation most likely lives here or in the 1993 book, since the 2002 *Policy Dynamics* intro chapter (read in full) uses the term as already established and never cites Eldredge or Gould.
3. **Eissler, R., Russell, A. & Jones, B.D. (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 and squarely about PET's own origin; the most promising lead for a primary-pen confirmation. Only its abstract (scholars.uky.edu) was checked at capture, and the abstract alone did not mention Eldredge or Gould.

**Why it matters / what's load-bearing:** the kept claim-note is a genuine cross-domain lineage finding — the contrast case to the cricket-laws borrowing ([[claim-cricket-laws-phase-transition-independent-of-punctuated-equilibrium]]). The lineage itself is solid at Tier 2–3 (two independent witnesses); what is unverified is specifically the primary-text receipt. A direct read would let the note advance past `seedling`.

**Negative result already on record (not to be re-run):** Mortensen & Dias's 2022 "A bibliography of punctuated equilibrium studies" (author-hosted, Tier 1) does **not** list Eldredge & Gould 1972 — but that document is scoped to policy-studies applications of PET, not foundational biology, so its absence is a scope mismatch, not evidence against the lineage. The 1991 *Agendas and Instability* book proposal ("The Politics of Disequilibrium") used "disequilibrium" rather than "punctuated equilibrium," suggesting the explicit biological framing entered between the 1991 proposal and 1993 publication — a further lead on *when* the citation was adopted.

**How to get in:** the 1993 book and 1999 Sabatier-volume chapter are gated behind their publishers with no author-hosted PDF found; a future session with library/JSTOR access, or a reachable scan of the 1993 Chapter 1, would settle it. Medium priority — the note is honest and well-sourced at the secondary level; this closes the last rung.
