For most of American political history, civic capacity was treated as background infrastructure — something that existed, served various functions, and did not require deliberate attention. The assumption was that it would sustain itself. The research of the past three decades suggests that assumption was wrong, and that its consequences are now measurable.
The academic literature on civic decline, political instability, and democratic resilience has converged on a set of findings that are uncomfortable to state plainly but that the evidence supports: civic capacity is not a luxury of stable democracies. It is one of the structural conditions that makes stability possible in the first place. When it atrophies over long periods, the preconditions for political instability accumulate. That is where the United States is now, according to multiple independent lines of research.
Turchin’s Structural-Demographic Theory
The most systematic attempt to model the relationship between structural conditions and political instability comes from complexity scientist and historian Peter Turchin, whose work in cliodynamics — the quantitative analysis of historical cycles — has produced a framework for understanding why societies move through periods of stability and breakdown.
Turchin’s structural-demographic theory models human societies as systems with three main components: the general population, the elites, and the state. The theory tracks how changes in these components and their interactions generate political stress over time. The framework identifies three primary precursors of instability: popular immiseration (declining real wages and living standards for most people), elite overproduction, and state fiscal distress.
Elite overproduction is the concept that has attracted the most attention. The theory describes it as the condition in which elite numbers and elite aspirants exceed the number of positions that carry real institutional authority. As the pool of credentialed, status-seeking elites grows faster than the structural positions that confer genuine power, the surplus creates a large class of individuals with high expectations and blocked paths — and those individuals eventually become the social base for political disruption. As Turchin documented in Ages of Discord, elite overproduction is not primarily about greed or pathology. It is a structural outcome of earlier periods of abundance and educational expansion that produced more credentialed aspirants than institutional authority could absorb.
The mechanism matters here. Intraelite competition intensifies as the surplus grows. Elites who cannot achieve the positions they expected do not quietly accept diminished status — they compete harder, undermine rivals, and are more likely to mobilize popular grievances to advance their own positions. This is what Turchin means by intraelite conflict: not simply disagreement among people at the top, but a structural condition in which large numbers of frustrated aspirants compete destructively for a fixed or slowly growing supply of apex positions. The social norms of cooperation that made elite conflict manageable in integrative periods unravel as competition intensifies.
Turchin’s analysis of American history identified two prior peaks of structural instability: the antebellum period preceding the Civil War, and the period of rising inequality and social conflict in the late nineteenth and early twentieth centuries. His structural indicators — tracked through the Political Stress Index, which integrates popular immiseration, elite overproduction, and state fiscal distress — show the current period reaching levels comparable to those prior peaks. In his structural-demographic analysis, Turchin identified the 2020s as a predicted peak of instability, a forecast made nearly a decade before the events of the 2020s began confirming the pattern.
The framework has critics. A 2023 empirical test published in PLOS ONE found that while the theory’s predictions about wage dynamics and elite numbers held up in industrial democracies, elite overproduction did not directly predict the Political Stress Index in recent decades — with rising inequality appearing to be the more direct driver. This is an important qualification. The structural-demographic theory is a model of complex systems, not a deterministic prediction machine, and the specific causal pathways it traces remain subjects of empirical debate. What the research does establish is that the structural conditions the theory tracks — inequality, institutional trust collapse, elite fragmentation — are measurable, are rising, and have historically preceded periods of major instability.
Putnam and the Social Capital Evidence
Robert Putnam’s research program, developed over three decades and synthesized in Bowling Alone (2000), approached civic decline from a different angle. Where Turchin tracked structural-demographic variables, Putnam tracked social capital — the networks of civic engagement, norms of generalized reciprocity, and trust that allow people to coordinate, solve collective problems, and exercise political voice.
Putnam’s central finding was that social capital in the United States increased during the first two-thirds of the twentieth century and then began declining sharply — a decline traceable across seven independent measures including political participation, civic participation, religious participation, workplace networks, informal social networks, mutual trust, and altruism. The decline was not a polling artifact. It showed up consistently across different data sources, different time periods, and different communities.
The political consequences Putnam identified were direct: communities with high social capital showed better governance, lower corruption, faster economic development, lower crime, and more effective public institutions. The connection ran in both directions — social capital made political institutions more responsive, and effective institutions reinforced civic engagement. The corollary is equally important: communities without it showed the reverse pattern. When social capital atrophies, the civic substrate that makes political accountability possible thins out.
Putnam was careful not to romanticize what was lost. The civic associational life of mid-twentieth-century America was racially exclusive in significant ways, and much of the social capital it built was bonding capital — capital within groups — rather than bridging capital that connected across difference. The Progressive Era associations that Putnam invoked as models were also, in many cases, engines of racial and class exclusion. That caveat matters. But it does not negate the finding that organized civic engagement correlates with better political outcomes, and that its decline correlates with the reverse.
Skocpol and the Organizational Transformation
Theda Skocpol’s contribution to this literature identified a structural change in how civic organizations work that Putnam’s social capital framework did not fully capture. In Diminished Democracy, Skocpol documented the transformation of American civic life from membership-based, cross-class federated organizations to professionally managed advocacy groups.
The historical American civic model — exemplified by organizations like the American Legion, the Elks, the PTA, and hundreds of comparable cross-class membership associations — had a specific structure. They were federated across local, state, and national levels. They required active participation from members at the local level. They created organizational channels through which ordinary Americans who were not professional advocates could have their interests represented at higher levels of political organization. They were imperfect in many ways, but they were genuinely mass organizations with genuine membership.
What replaced them, Skocpol argued, was a different model: professionally staffed advocacy organizations based in Washington and other urban centers, funded by foundations and large donors, representing membership primarily in the nominal sense of a mailing list. These organizations can do many things — produce policy research, run media campaigns, file litigation — but they do not build civic capacity among ordinary people in the way membership organizations did. They represent interests from the top down rather than aggregating participation from the bottom up.
Skocpol’s critique of Putnam was that he misdiagnosed the challenge. The problem was not primarily an aggregated decline in individual civic behavior. It was a structural transformation in how civic organizing was organized — a shift away from models that built participation capacity and toward models that substituted professional management for it. The implications for civic infrastructure are significant: a civic landscape dominated by professionally managed advocacy groups may produce sophisticated policy advocacy while failing to build the organized civic capacity that makes democratic accountability function.
Levitsky and Ziblatt on Democratic Backsliding
Steven Levitsky and Daniel Ziblatt’s How Democracies Die (2018) approached the question of democratic stability from a comparative politics perspective. Their central argument was that contemporary democratic breakdown does not look like the historical model of a military coup or revolutionary takeover. It looks like a slow erosion from within — elected leaders gradually undermining the institutions and norms that constrain their power.
The most useful contribution for this discussion is their emphasis on democracy’s informal infrastructure — the norms, unwritten rules, and what they call “soft guardrails” that prevent normal political competition from becoming destructive. Mutual toleration (the acceptance of political opponents as legitimate rivals) and institutional forbearance (restraint in the use of formal powers) are not written into constitutions. They are maintained by civic norms — norms that are sustained, in part, by civic organizations that enforce expectations and hold political actors accountable.
The implication is that democratic resilience depends not only on formal institutional structures but on the informal civic infrastructure that maintains the norms those structures require. When civic capacity weakens, the informal guardrails weaken with it. Political actors who might previously have been constrained by the civic costs of norm violations find those costs reduced when the civic organizations capable of imposing them have atrophied.
The Historical Pattern of Civic Surges
The research literature points toward a historical pattern in American politics that is important for understanding the current moment. The periods of peak instability in American history were not resolved by government action alone. They were addressed — when they were addressed — by surges of civilian organizing that rebuilt civic capacity and changed the political calculus.
The Progressive Era (roughly 1890s to 1910s) emerged from a period of intense inequality, elite conflict, and institutional dysfunction comparable in structural terms to what Turchin identifies as a disintegrative peak. What resolved it — partially and imperfectly — was not primarily top-down government action but an enormous wave of civic organization-building: the proliferation of reform associations, settlement houses, labor unions, professional associations, women’s organizations, and cross-class federated civic bodies that Putnam and Skocpol both document. That civic infrastructure created the organized constituency for Progressive Era political reform and the institutional capacity to implement it.
The New Deal period showed a similar pattern. The organizational infrastructure built during the Progressive Era and expanded through the 1920s and 1930s — particularly the labor movement — created the civic capacity for the political coalition that enacted the New Deal. As Turchin has observed, the New Deal did not create the integrative trend of the mid-twentieth century through government action alone. It worked with and through the civic infrastructure that had been built over the preceding decades.
The mid-century integration trend that followed — characterized by declining inequality, rising civic participation, relatively high institutional trust, and effective government performance — was not just a policy achievement. It was built on civic infrastructure: membership organizations, labor unions, community associations, and civic bodies that created organized participation across class lines.
That infrastructure began eroding in the 1970s. The structural conditions Turchin tracks have been moving in the disintegrative direction since then. Putnam’s social capital data shows the same trajectory. Skocpol’s organizational analysis shows the same structural transformation.
What the Research Suggests About the Current Moment
The structural-demographic indicators Turchin tracks — real wage stagnation for most workers, rising inequality, elite fragmentation, institutional trust collapse, state fiscal stress — currently resemble the conditions preceding prior instability peaks. That is not a prediction of a specific outcome. Structural conditions establish probabilities, not certainties. The Civil War was not the inevitable consequence of the antebellum instability peak; it was one possible outcome among others, and different choices might have produced different results.
What the research does suggest is that the current structural conditions require a civic response — the kind of organized civilian capacity-building that historically has been the mechanism by which structural crises get addressed rather than simply detonated.
That response is not guaranteed. One feature of the current moment that the research identifies as unusual is the weakness of the organizational infrastructure available to mount it. The membership organizations that provided the civic backbone for prior resolutions have largely been replaced by professional advocacy organizations that do not build participation capacity in the same way. The labor movement has contracted dramatically. Local news — a form of civic infrastructure that Tocqueville identified as essential to American civic life — has collapsed in hundreds of communities.
The research does not specify what a rebuilt civic infrastructure should look like. That is partly an empirical question about what forms of civic organization work in contemporary conditions, and partly a political question about what different communities and constituencies need. What the research establishes is the structural importance of the question. Civic capacity is not optional in periods of structural stress. It is one of the variables that determines whether structural crises produce reform or rupture.
America’s Plan is an early-stage project attempting to address part of this problem — specifically, the problem of building civilian-led civic infrastructure for long-term planning and accountability. Whether that particular approach contributes meaningfully to rebuilding civic capacity is an open question. The research reviewed here establishes why the problem it addresses is serious, and why the absence of sustained civilian-led civic infrastructure is not merely a procedural gap but a structural condition with measurable political consequences.
The historical record is consistent on this point: organized civic capacity has been a precondition for managing structural crises. The research is less clear on what that capacity needs to look like in contemporary conditions, or whether existing organizations and projects will be adequate to the moment. Those are questions the current period will answer empirically.
