| 4 | +OSF, Dryad, IDEAS/RePEc and publisher pages. "Verified" = bibliographic record confirmed by Crossref/Europe PMC or a | ||||

| 8 | +## 1. Shin, Price, Wolpert, Shimao, Tracey & Kohler (2020) | ||||
| 9 | +Citation (verified, Europe PMC PMC7224170): Nature Communications 11, 2394, DOI 10.1038/s41467-020-16035-9. | ||||
| 10 | +Claim: development proceeds in phases — scale growth, then information-processing/economic growth, then further scale; | ||||
| 11 | +a "Scale Threshold" (PC1 ≈ −2.5) and an "Information Threshold" (PC1 ≈ −0.5). Data: Seshat, 285 polities, 30 NGAs, | ||||
| 12 | +414 polity-centuries, nine CCs. Method: PCA; PC1 77.2% (loadings PolPop 0.93, PolTerr 0.85, CapPop 0.89, levels 0.90, | ||||
| 13 | +gvrnmt 0.88, infrastr 0.88, writing 0.87, texts 0.92, money 0.80); PC2 ≈ 6% opposes scale (negative loadings) to | ||||
| 14 | +information (positive). On instability: explicitly hypothetical — "mismatch among aspects of social development should | ||||
| 15 | +be considered as a generic cause of instability"; Seshat "too small" to test; "a topic for future research". | ||||
| 16 | +Relation: closest existing hypothesis; never operationalizes a mismatch index, never links to CrisisDB, no predictive test. | ||||
| 17 | + | ||||
| 18 | +## 2. Johnson (1982) | ||||
| 19 | +Citation (verified via library records; chapter not read): in Renfrew, Rowlands & Segraves (eds.), Theory and | ||||
| 20 | +Explanation in Archaeology, Academic Press, pp. 389–421, ISBN 0-12-586960-6. Content known through Alberti (2014, | ||||
| 21 | +PLoS ONE, PMC3953443) and annotations: scalar stress grows disproportionately with units per level; fission or added | ||||
| 22 | +hierarchy; modal ~6 units per level; Alberti estimates a fission threshold near 127 persons (Hutterites). Relation: | ||||
| 23 | +theoretical ancestor; no cross-polity instability test. | ||||
| 24 | + | ||||
| 25 | +## 3. Wright & Johnson (1975) | ||||
| 26 | +American Anthropologist 77(2), 267–289; DOI 10.1525/aa.1975.77.2.02a00020 (confirmed by Crossref in the main session). | ||||
| 27 | +State = administrative hierarchy of ≥ 3 decision levels; population growth and exchange rejected as sufficient causes | ||||
| 28 | +(Susiana survey data). Relation: definition of K; not about instability. | ||||
| 29 | + | ||||
| 30 | +## 4. Turchin et al. (2018) | ||||
| 31 | +PNAS 115(2), E144–E151, DOI 10.1073/pnas.1708800115 (verified). 414 polity-centuries, 30 regions, 51 variables → 9 CCs; | ||||
| 32 | +PCA with multiple imputation; PC1 ≈ 77%. Relation: D- and K-type variables share PC1 → mismatch is a residual. | ||||
| 33 | + | ||||

| 36 | +>100,000 combinations; best: agricultural productivity × military technology. Relation: growth, not instability. | ||||
