The Collapse Trigger Matrix is not a doom feed. It is a structured measurement instrument. Every number on the dashboard — every severity score, every precondition card, every cascade arrow — is grounded in a body of academic work on how complex societies actually break down. This page exists so a first-time visitor can understand what they are looking at: what each metric measures, why it was chosen, and how it ties back to the two researchers whose work forms the analytical spine of the matrix — Peter Turchin and his structural-demographic theory, and Luke Kemp and the argument set out in Goliath's Curse. It also maps the secondary scaffolding: Goldstone, Minsky, Deaton, Ferguson, Polanyi, Tainter, Scheidel, and the survival-analysis work of Scheffer and colleagues.
The matrix fuses two complementary lenses. They were chosen because they are quantitative rather than anecdotal, because both survive cross-validation against large datasets, and because they answer different halves of the same question: how much pressure, and how brittle the container.
Peter Turchin is an evolutionary biologist who turned the quantitative toolkit of population ecology onto human history, founding the field he named cliodynamics. The core of his work is structural-demographic theory (SDT) — a model, originally devised by historical sociologist Jack Goldstone and later mathematically formalized by Turchin and Andrey Korotayev, that explains political instability as the product of three slow-moving structural forces rather than the actions of individuals.
SDT identifies three engines that, when they move together, drive a society from an integrative (stable, cohesive) phase into a disintegrative (unstable, fragmenting) one:
The connecting mechanism is what Turchin calls the "wealth pump" — an institutional arrangement that transfers income from labor to the asset-owning elite. The same pump immiserates commoners and overproduces elites, so the two pressures rise in lockstep. Turchin compresses these forces into a composite Political Stress Indicator (PSI, or Ψ): when PSI crosses a threshold, instability becomes structurally favored — not certain, but the path of least resistance.
The model is empirically anchored in the Seshat Global History Databank and the associated CrisisDB project, and has been back-tested against secular cycles in Rome, China, France, England, the Ottoman Empire, and the United States. In a 2010 Nature commentary Turchin used SDT to forecast that political instability in the West would peak in the 2020s — a prediction that has aged conspicuously well.

Luke Kemp is a research affiliate at the University of Cambridge's Centre for the Study of Existential Risk. His 2025 book Goliath's Curse: The History and Future of Societal Collapse is a "deep systems" survey of collapse — a historical autopsy spanning roughly five millennia and several hundred societal lifespans, from the first Egyptian dynasty to the modern era. Where earlier collapse literature (Jared Diamond's Collapse, for instance) leaned on a handful of case studies, Kemp's argument rests on the largest dataset he could assemble.
Kemp's central object of study is the "Goliath" — a large-scale, hierarchical political order built on dominance, force, and elite rule. Goliaths are spawned by what he calls "Goliath fuel": concentratable, lootable resources — grain, fossil fuels, weapons, and now digital technology — that let a small group capture power over information, politics, and the economy. His thesis is that this same fuel is a double-edged sword:
One counterintuitive thread runs through the book and is worth flagging for any reader of this dashboard: historically, collapse has often been a release for ordinary people, not a catastrophe — weaker, more fragmented successor authority frequently improved local conditions. Kemp's warning is specifically about this collapse: a tightly-coupled global system with humanity-ending tail risks attached.

Turchin and Kemp are the spine, but the matrix cross-references a wider literature. Each theorist below is invoked at specific points in the metric definitions; this section is the key to those references.
The originator of structural-demographic theory. Goldstone's state-breakdown model showed that revolutions cluster where fiscal distress, elite competition, and mass mobilization potential rise together. Turchin formalized his framework; in 2020 the two jointly forecast sustained US unrest. Invoked across the governance and fiscal metrics.
"Stability is destabilizing." Minsky argued that long calm periods push financial actors from hedge finance toward speculative and Ponzi finance, until a "Minsky moment" forces a disorderly unwind. The backbone of the matrix's credit, household-debt, and shadow-banking metrics.
Nobel laureate Deaton and Case documented rising mortality from suicide, alcohol, and drugs among working-age Americans without college degrees. This work is the independent corroboration of Turchin's immiseration engine, and grounds the life-expectancy metric.
Ferguson argues that complex systems do not decline gracefully — they appear stable until they fail suddenly, because tightly-linked networks transmit shocks faster than hierarchies can respond. The basis of the matrix's cascade-pathway logic and its emphasis on non-linear failure.
Polanyi's "double movement": when markets are dis-embedded from social control, society generates a protective counter-movement. Useful for reading polarization, populism, and de-globalization not as noise but as predictable backlash against the wealth pump.
Tainter's thesis: societies solve problems by adding complexity, but complexity has diminishing marginal returns; eventually the cost of maintaining the system exceeds its benefit. Directly relevant to the infrastructure-grade and state-capacity metrics, and a key influence on Kemp.
A sobering empirical claim: across history, large inequality has only ever been compressed by catastrophic "levelers" — mass war, revolution, state collapse, plague. Frames why the wealth-inequality metric is treated as a structural rather than a cyclical variable.
The survival-analysis study — co-authored by Luke Kemp — showing that the risk of state termination climbs steeply over a polity's first ~two centuries, then plateaus, giving the first quantitative evidence that state resilience declines with age. The empirical engine behind the matrix's resilience-loss score.
Five methods turn raw indicators into the numbers on the dashboard. Each is a deliberate analytical choice with a theoretical justification.
Each catalogued event carries a severity score estimating the magnitude of systemic damage if it were to occur — a blend of direct economic loss, breadth of contagion, and the difficulty of recovery. It is an analyst's ordinal estimate, not a probability. A score of 9–10 denotes an existential, cascade-capable event; 3–4 a compounding stressor that matters only in combination.
Why it is built this way: following Ferguson and Kemp, severity deliberately weights cascade potential heavily. An event is dangerous less for its first-order cost than for its capacity to detonate other events — which is why the scatter plot pairs severity against resilience loss rather than against probability.
For every event the matrix estimates how much worse the same shock would land today than it would have against the United States of 1998 — chosen as the last broadly-agreed period of fiscal, institutional, and social health. An average resilience loss of ~−48% means the system's shock-absorbing capacity is roughly half of what it was.
Why it is built this way: this is the matrix's Kemp axis. The Scheffer–Kemp survival-analysis finding — that state resilience erodes with age and scale — is operationalized here as a measurable decay rate. It separates the question "how big is the shock?" (severity) from "how brittle is the container?" (resilience), exactly the distinction the two frameworks were chosen to capture.
Events are sorted into four tiers: Tier 1 existential cascade triggers (severity 9–10), Tier 2 severe systemic stressors (7–8.9), Tier 3 significant destabilizers (5–6.9), and Tier 4 compounding stressors (3–4.9). Tiering communicates triage priority at a glance and structures the collapse thesis.
Why it is built this way: Turchin's secular-cycle work implies collapse is rarely one event — it is the coincidence of several. The working thesis the matrix tests is that a Russian-1990s-scale unraveling requires roughly two to three Tier 1–2 events inside an 18-month window while the slow Tier 3–4 erosions continue unchecked.
The dashboard's live cascade panel traces a shock through the system as an explicit chain — e.g. energy shock → inflation → forced central-bank positioning → Treasury yields → credit tightening → housing → social despair. Each node is either a live data point or a qualitative stage.
Why it is built this way: this is Ferguson's network-fragility thesis made operational, and it is how Turchin's three engines are linked to real-time market data. A cascade map shows not just that pressure is high but which transmission channel is currently carrying it.
Each of the 16 precondition cards carries a four-level status flag. These are the standing conditions that determine how a trigger event will propagate — the ground state of the system, monitored continuously rather than scored once.
Why it is built this way: the preconditions are, in effect, the live inputs to a Political Stress Indicator. Turchin's PSI combines mass-mobilization potential, elite-mobilization potential, and state fiscal health; the cards below are the contemporary, observable proxies for those latent variables.
Fiscal cluster These four metrics proxy Turchin's third engine — state fiscal distress — and Minsky's claim that debt structures grow fragile during long calm periods.
Total federal debt held by the public as a share of annual economic output — the standard gauge of a sovereign's debt burden relative to its capacity to service it.
A rising ratio narrows the fiscal room a state has to respond to crises — to fund stimulus, bailouts, defense, or social transfers. Past a point it also raises the perceived risk premium on new borrowing, which feeds back into the interest-burden metric. It is the single clearest reading of state capacity.
A direct measure of state fiscal distress — engine three. When fiscal room shrinks, the state loses the ability to buy social peace, accelerating the disintegrative phase.
An aging Goliath's costs outrun its benefits; mounting public debt is the ledger entry for that drift. Extractive systems borrow against the future to sustain present consumption.
Annual federal net interest outlays — in dollars, as a share of GDP, and as a share of federal revenue. It captures what the debt actually costs to carry, as distinct from its stock.
Interest is a non-discretionary claim on the budget that crowds out everything else. When it climbs past defense or major social programs in the spending rankings, it signals that the fiscal arithmetic has begun to compound on itself — debt service forcing more issuance, which raises yields, which raises debt service.
The sharp edge of fiscal distress. A state spending a fifth of revenue on interest has correspondingly less capacity to absorb shocks or dampen popular grievance.
A textbook "rising cost to citizens": interest paid to bondholders is, in distributional terms, a transfer from taxpayers to asset-holders — the wealth pump expressed as a budget line.
The creditworthiness assessment assigned to U.S. sovereign debt by the major rating agencies — and, just as importantly, the outlook (stable / negative) and the direction of recent revisions.
A rating is a third-party verdict on whether the fiscal trajectory is sustainable. A downgrade — or a shift to negative outlook — is a coordination signal that can raise borrowing costs system-wide and force forced-selling by mandate-constrained institutional holders.
A proxy for elite confidence in the state. When the financial elite formally marks down the sovereign, it signals erosion of the legitimacy and trust that hold the integrative phase together.
An external instrument registering declining resilience — the same "aging state" signal the survival-analysis work detects, here priced by markets rather than measured by historians.
Total outstanding consumer debt — mortgages, auto loans, credit cards, student loans — together with delinquency rates by category. The private-sector mirror of the federal fiscal metrics.
Household balance sheets determine how a financial shock transmits to the real economy. Elevated debt with rising delinquency means consumers have no buffer — a rate shock or job loss converts directly into defaults and demand collapse.
Debt-financed consumption is how popular immiseration is hidden: living standards are maintained on credit rather than on rising real wages, until the credit runs out.
Falling household net benefit, padded by borrowing — the Goliath's curse operating at the kitchen-table level.
Monetary & energy cluster These metrics track the live transmission channel — the fast-moving prices and rates through which a geopolitical or financial shock actually propagates. They are the matrix's real-time pulse.
The market yield on the 30-year U.S. Treasury bond — the long end of the curve, and the purest available reading of the market's long-run confidence in U.S. fiscal sustainability and inflation.
The long bond prices the cost of rolling the national debt. The matrix flags a specific non-linear threshold — the "Schiff trajectory": once the 30-year holds above roughly 5%, each additional 100 basis points adds an outsized increment to annual debt service after rollover, because the principal stack is so large. Above that inflection, 5→6% comes faster than 4→5%.
A continuously-updating gauge of state fiscal distress and elite confidence — arguably the highest-frequency PSI input available.
A real-time resilience meter: a rising long yield is the market pricing the Goliath's diminishing capacity to carry its own weight.
The market-implied probability of a Federal Reserve rate increase over a defined horizon, derived from fed funds futures pricing. The matrix tracks it alongside the implied probability of a cut.
It quantifies the "Fed policy trap" (catalogued as Event #27). When markets price a hike and a cut as both plausible, it reveals a central bank with narrowing options: cutting would validate energy-driven inflation; hiking would worsen debt-service math and freeze the credit channel. Lost optionality is itself a systemic-risk signal.
The monetary expression of declining state adaptive capacity — the toolkit for managing a shock is jammed precisely when a shock is active.
A complex Goliath whose central management institution can no longer act without triggering harm somewhere else — complexity past the point of diminishing returns.
The EIA Europe Brent Spot Price (FOB) — the U.S. Energy Information Administration's free daily physical-market assessment, closely tracking Dated Brent. This is deliberately the spot price — what a physical importer actually pays today — not an ICE front-month futures price, which reflects a different instrument.
Oil is the master transmission variable of the active cascade. An energy shock feeds inflation within weeks, which constrains the Fed, which moves Treasury yields, which tightens credit. Brent is the first domino, and the EIA spot series is the metric that correctly represents the real economic cost.
An external shock amplifier. SDT holds that triggers strike a system already loaded with structural pressure — an oil spike is the spark to Turchin's accumulated tinder.
Fossil energy is paradigmatic "Goliath fuel," and Kemp names the fossil-fuel industry an agent of doom. A supply shock is the curse turned acute.
The U.S. dollar's share of allocated global foreign-exchange reserves, reported quarterly by the IMF's COFER database. A proxy for the dollar's standing as the world's reserve currency.
Reserve-currency status is what lets the U.S. run large deficits at low cost — "exorbitant privilege." A slow decline in the dollar's share is a slow erosion of that privilege, and a leading indicator for the petrodollar and de-dollarization events in the matrix.
Reserve status is a deep structural foundation of U.S. state capacity. Its erosion is the geopolitical-finance counterpart to internal fiscal distress.
The single global Goliath partly rests on dollar hegemony; a falling reserve share is one measurable thread of that order loosening.
The direction and persistence of 30-year fixed mortgage rates, read together with lender behavior — tightening FICO cutoffs and underwriting overlays — that does not show up in the headline rate.
Housing is the largest single household asset and the most rate-sensitive part of the real economy. Sustained rate increases plus quiet credit-box tightening — currently concentrated in the 640–720 FICO band — squeeze first-time and middle-income buyers and can freeze transaction volume well before prices visibly move.
Blocked access to housing is a concrete form of immiseration and of frustrated mobility — the lived experience behind the credentialed-precariat dynamic.
Rising cost of a basic good with no offsetting benefit — the curse measured at the level of the household ledger.
These metrics proxy Turchin's first engine — popular immiseration — and the legitimacy and cohesion variables that determine whether a society can absorb a shock together or fractures under it. They are the heart of the Political Stress Indicator.
The University of Michigan Index of Consumer Sentiment — a monthly survey of how households perceive their financial situation and the economic outlook.
Sentiment is partly self-fulfilling: pessimistic households cut spending, which slows the economy, which validates the pessimism. A sharp drop — especially below pandemic-era lows — signals that the population's psychological buffer is thin.
The subjective face of immiseration. SDT cares not only about objective well-being but about the perceived gap between expectations and reality, which is what mobilizes people.
An early reading of the breakdown of the "all in it together" belief that Kemp identifies as the load-bearing wall of any Goliath.
The share of the public that approves of the job Congress is doing, tracked longitudinally by Gallup.
Congress is the institution that must legislate the response to any slow-moving crisis — entitlement reform, fiscal adjustment, disaster funding. Approval in the low double digits is a measure of how little political capital exists to do exactly that.
A direct read on declining state legitimacy — the soft side of engine three. Legitimacy is what lets a state act without coercion.
Falling benefit-to-citizen perception aimed at the governing institution itself — consent visibly draining from the Goliath.
The ideological and affective distance between partisans — both policy disagreement and the degree to which each side views the other as a threat. Tracked through long-run survey work, principally by Pew Research.
Polarization is the variable that converts every other stressor into gridlock. A polarized polity cannot form the broad coalitions needed to legislate crisis responses, and is far more vulnerable to the zero-sum, norm-breaking competition that drives disintegration.
The political signature of elite overproduction. Surplus elite aspirants compete by mobilizing mass factions against each other; polarization is what that competition looks like from the outside.
Status competition — which Kemp places at the center of collapse — scaled up to the level of mass political identity.
The share of the public expressing trust in core institutions — especially the federal government — tracked by Pew and Gallup over decades.
Trust is the invisible infrastructure of crisis response: it determines whether people comply with public-health measures, accept election outcomes, hold their savings in the banking system, and believe official information. Low trust raises the cost and lowers the effectiveness of every state action.
One of the clearest summary indicators of where a society sits in the integrative–disintegrative cycle. High-trust societies are, almost by definition, in the integrative phase.
The "all in it together" belief, measured directly. Kemp's argument is that once it fails, even small shocks become collapse triggers.
U.S. life expectancy at birth, reported by the CDC's National Center for Health Statistics — and, by extension, the "deaths of despair" (suicide, alcohol, drug overdose) that have weighed it down.
Life expectancy is the hardest, least-spinnable measure of population well-being. A wealthy country whose life expectancy stalls or falls — and lags every G7 peer — is sending an unambiguous signal that something structural is wrong with the lived experience of its population.
The gold-standard proxy for popular immiseration — engine one. Turchin treats falling well-being, especially mortality, as a leading structural pressure.
The ultimate "declining benefit to citizens": under an extractive Goliath, the population is, measurably, not living as long as it should.
Structural cluster These two metrics move slowly and rarely reverse without a major event. They are the deep parameters of the system — the variables Turchin's wealth pump and Kemp's curse act through.
The concentration of wealth — most directly the share of total net worth held by the top 1% — drawn from the Federal Reserve's Distributional Financial Accounts.
Inequality is not merely a fairness question in this framework; it is the master structural variable. It is simultaneously the output of the wealth pump and the input to elite overproduction, popular immiseration, and the collapse of social cohesion.
The single number that best summarizes the wealth pump. Turchin's exit condition for a disintegrative phase is, essentially, reversing it — historically rare and difficult.
Kemp's "constant variable" — the recurring Achilles' heel that, across hundreds of cases, sooner or later causes every Goliath to buckle.
The American Society of Civil Engineers' periodic letter-grade report card on U.S. physical infrastructure — roads, bridges, water, energy, transit — together with the estimated investment gap.
Infrastructure is the literal substrate on which the economy and crisis response run. A mediocre grade and a multi-trillion-dollar investment gap mean reduced redundancy — fewer backup paths when a shock hits, and a higher chance that one failure cascades into others.
Physical evidence of declining state capacity: a state in fiscal distress defers maintenance, and deferred maintenance is borrowed-against resilience.
A direct reading of declining resilience — exactly the "aging state" effect, here measured in concrete and steel rather than in survival curves.
The matrix catalogues 27 trigger events. The preconditions above are the standing state of the system; the events are the shocks that test it. Each event below is tagged with the framework lens most relevant to reading it — T for Turchin's internal-pressure dynamics, K for Kemp's resilience / Goliath-aging lens, M for Minsky financial fragility, F for Ferguson network cascades. The full live scoring lives on the matrix dashboard.
