The Hidden Circuitry of the Four Turnings

The Neuroeconomic Cycle Driving Empathy, Fear, and the Shape of History

What if history doesn’t just repeat, but pulses—rising and falling in ways we rarely notice until it’s too late?

This article started as a simple list of events that shaped the world we live in. But as I followed the threads, I found something deeper—a hidden feedback loop connecting economic stress, brain chemistry, ideological shifts, and the cycles of history described by Strauss and Howe’s “Four Turnings.”

The Hidden Circuitry of the Four Turnings explores that loop, how it might explain the rhythm of fear and hope that shapes our society, and whether we might soften the impact of the next wave before it crashes.

Who This Is For

This essay is for curious readers—those who sense deep patterns behind the chaos of modern life, and want a clearer picture of how history, psychology, and society interlock. You don’t need a background in neuroscience or generational theory. Just bring your intellect, your instincts, and a willingness to follow the deeper currents beneath our political storms.

1. The Hidden Circuitry of the Four Turnings

What if history doesn’t just repeat—it pulses?

For decades, the Strauss–Howe generational theory has described an 80-year cycle of American history, divided into four “Turnings”: a High, an Awakening, an Unraveling, and a Crisis. In this view, history isn’t linear, but rhythmic—an echoing pattern of social moods rising and falling through generations. But while the Turnings map the shape of history, they don’t explain why the cycle
occurs. What drives it? What gives it force, urgency, emotion?

What if the answer lies inside us?

Emerging research in neuroscience and psychology suggests that mass behavior—ideological rigidity, empathy, rebellion, conformity—may be influenced by more than just events. Our economic conditions influence our biology, especially brain chemistry like dopamine, which governs motivation, fear, openness, and trust. When the economy crashes, dopamine drops. When hope rises, so does flexibility. Fear tightens us. Safety relaxes us. And these chemical shifts ripple outward into politics, crime, culture, and collective identity.

This article explores a new idea: that the Four Turnings may be underpinned by a multi-level feedback loop connecting economics, brain chemistry, ideology, leadership, and institutions. A system that moves not just across time, but through us.

If this circuitry exists, can we see the warning signs as we approach another breaking point? And if we can’t stop the cycle entirely, could we at least soften its hardest turns?

2. A Brief Tour of the Four Turnings

History doesn’t move in straight lines—it moves in seasons.

According to Strauss and Howe, American history cycles through a repeating pattern roughly every 80 to 100 years, called a saeculum. Each saeculum is divided into four Turnings, each lasting about 20–25 years, reflecting a generational mood swing that reshapes society.

These are the Four Turnings:

1. The High – A time of collective confidence and institutional strength, following a major crisis. Post–WWII America (1946–1964) is the textbook High: the GI Bill, infrastructure, rising middle class, strong labor unions, and a shared belief in the American Dream.
2. The Awakening – As prosperity grows stale, the next generation pushes back. This is a time of spiritual upheaval and questioning of established norms. Think of the 1960s and 1970s: civil rights, anti-war protests, feminism, environmentalism, the counterculture.
3. The Unraveling – Institutions weaken. Cynicism rises. Trust erodes. Individualism peaks while the social fabric frays. The 1980s–2000s saw deregulation, wealth inequality, and the rise of culture wars.
4. The Crisis – The unraveling reaches a breaking point. Institutions fail. Conflict surges. The 2008 financial crash, climate emergencies, and political extremism may mark our current era.

It’s worth noting that not every Turning arrives on a precise schedule. Historical crises and realignments sometimes come earlier or later than expected, and Strauss and Howe’s timeline predictions have faced fair criticism. But this doesn’t weaken the feedback model beneath the Turnings. The circuitry described here is less about fixed dates and more about recurring human dynamics shaped by economic, emotional, and institutional forces.

Where we go next depends on how this Crisis resolves.

Saeculum	High	Awakening	Unraveling	Crisis
Revolutionary	Colonial Order (1701–1746)	First Great Awakening (1746–1773)	Imperial Strain (1773–1794)	American Revolution (1794–1820)
Civil War	Jacksonian Era (1820–1844)	Transcendental Awakening (1844–1860)	Sectional Conflict (1860–1865)	Civil War & Reconstruction (1865–1884)
Great Power	Gilded Age Stability (1884–1908)	Progressive Upheaval ( 1908–1929)	Roaring Twenties (1929–1939 )	Great Depression & WWII (1939–1946)
Millennial	Postwar Consensus (1946–1964)	Counterculture Rebellion (1964–1984)	Culture Wars/ Neoliberalism (1984–2008)	Financial Collapse to Present (2008–?)

3. The Chemistry of Fear and Hope

Dopamine is often called the “reward chemical,” but it’s more accurate to say it governs how motivated we feel—how much we care, how much we want something, and how open we are to risk and new experiences.

When dopamine levels are high, people feel optimistic, flexible, and energized. They explore. They trust more easily. They can imagine a better future and work toward it. When dopamine is low, the opposite happens: fear rises. People become rigid, suspicious, protective. They cling to certainty and close ranks. Creativity and empathy decline.

This isn’t just personal. When large numbers of people experience stress and uncertainty at the same time, their collective dopamine tone can shift. You see it in rising crime, addiction, conspiracy theories, and authoritarian movements. You also see it in declining trust, political polarization, and social fragmentation.

Dopamine isn’t just a brain chemical; it’s a social weathervane.

But dopamine is only half the equation. As uncertainty becomes chronic, cortisol, the body’s primary stress hormone, rises. While dopamine promotes openness and exploration, cortisol reinforces vigilance, control-seeking, and fear. When it stays elevated over time, it impairs memory, narrows focus, and reduces emotional regulation. Societies saturated in cortisol feel overwhelmed, not just politically but cognitively. The brain rewires itself for survival, not imagination. The result isn’t just stress, it’s structural.

You can think of dopamine as the thermostat of a society’s mind. Just as thermodynamics governs how heat and energy flow through physical systems, dopamine helps regulate the flow of mental and emotional energy, like motivation, curiosity, and trust. When social conditions feel stable and hopeful, dopamine levels rise. That fuels exploration, flexibility, and imagination. But when stress and chaos dominate, dopamine drops, and with it comes fear, rigidity, and withdrawal. Like a heat engine shifting modes, society’s cognitive climate changes, seeking predictability over openness. This shift isn’t just emotional, it’s informational. People aren’t just reacting to threats; they’re trying to reduce uncertainty and restore a sense of order, even if it means becoming more closed-off or authoritarian.

3.1. Generational Chemistry

The Four Turnings aren’t just political or cultural phases, they’re neurochemical climates. As one generation comes of age under rising stress, and another under rising possibility, their baseline chemistry diverges. Each generation becomes conditioned by the neurochemical atmosphere they inhale during their formative years.

For example, Artist generations often grow up during Crises, when stress is high and order is imposed. They experience strong external structure and tend to internalize a high degree of social sensitivity and conformity. Nomads, on the other hand, often come of age during Awakenings, when institutions are questioned, disorder rises, and adults seem distracted. Their emotional environment is less stable, their protections more fragmented, and the result is a generation more skeptical, self-reliant, and pragmatic.

These are not just psychological profiles, they reflect social neurobiology. Cortisol and dopamine shape our openness, trust, impulsivity, and worldview. If you grow up surrounded by order, predictability, and optimism, your brain wires one way. If you grow up in chaos, distrust, or neglect, it wires another. Each generation carries the fingerprint of its chemical upbringing, and those fingerprints add up to social mood swings that are anything but random.

4. Layer One: The Economic Pulse of Society

Every cycle needs a rhythm. For civilizations, that rhythm is often economic.

When the economy is growing—when wages rise, jobs feel secure, and basic needs are met—people feel safe enough to plan for the future. They invest in their communities. They raise families with confidence. They trust institutions, because those institutions seem to be working.

But when the economy falters, everything changes. Insecurity takes root. Jobs vanish or feel precarious. Prices rise, savings shrink, futures blur. Economic stress is more than numbers on a spreadsheet—it’s psychological destabilization at scale.

This isn’t abstract. In the post–World War II era, America experienced a historic boom: veterans returned to good jobs, bought homes, and built a thriving middle class. It was a time of rising expectations, union strength, and broad-based opportunity.

But beginning in the 1970s and accelerating through the ’80s and ’90s, things began to shift. Deregulation, outsourcing, and automation hollowed out the working class. Real wages stagnated. Entire towns lost their economic purpose. By the time the 2008 financial crash hit, millions were already teetering on the edge.

These economic shocks didn’t just reshape the balance sheets—they reshaped the mood of the nation. And that mood is where the cycle takes its next turn.

5. Layer Two: Dopamine and the Emotional Climate

The saeculum isn’t just a cultural pattern. It’s a layered system, with feedback loops running across economics, biology, and ideology.

We’ve already described how economic boom-and-bust cycles create cascades of opportunity and stress that affect dopamine tone. But there’s a deeper chemical rhythm behind the cultural story, a push and pull between dopamine and cortisol.

In First Turnings, the world feels orderly, structured, and optimistic. Cortisol is low, dopamine is relatively high. Institutions feel trustworthy. Second Turnings (Awakenings) challenge that trust. Disorder and tension rise. Cortisol increases, and with it, rebellion and emotional volatility. Third Turnings (Unravelings) burn out what’s left of the old moral order. As institutions collapse and individualism soars, cortisol often remains elevated, but is met with cynicism, addiction, and distrust. Fourth Turnings bring systemwide stress. Cortisol dominates. But in the fire of shared struggle, something shifts: coherence. Clarity. People begin to realign, and dopamine slowly starts to rise—preparing the ground for the next First Turning.

The result is a long biological arc: hope to challenge to chaos to cohesion, and back to hope again. Not in everyone, and not all at once. But enough to shift the emotional chemistry of a society over time.

This cycle isn’t metaphysical. It’s molecular. And it explains why the saeculum continues to turn, even when nobody wants it to.

It’s not just political and economic threats that trigger these neurochemical shifts. The physical world is now reacting too. Ecological systems, long strained by centuries of expansion and extraction, are reaching their own limits. Melting ice, dying forests, disrupted weather patterns: these are not just background crises. They are direct consequences of past optimism, fueled by high dopamine societies that prioritized growth and innovation over restraint. Now, as climate tipping points trigger cascading consequences, they are becoming a new, external source of uncertainty and chronic stress. The result is a biological feedback loop between human systems and natural ones: climate collapse doesn’t just result from social breakdown—it now feeds it, reinforcing the very cortisol-driven behaviors that make coordinated response more difficult. In this way, ecological tipping points are no longer outside the circuitry. They are woven into it.

6. Layer Three: Ideology in a Chemical Mirror

Ideology doesn’t float in a vacuum—it rises from how people feel.

When dopamine is high, people tend to be more open: to new ideas, unfamiliar people, uncertain futures. Liberalism, in the broadest sense—not just politically, but psychologically—flourishes in these times. So does empathy. People believe that problems can be solved, systems can be reformed, and strangers can be trusted.

But when dopamine drops, the ideological climate hardens.

A society under chronic stress becomes less flexible. People crave certainty, clarity, and strong in-group identities. Fear makes nuance intolerable. Complexity feels like a threat. In these conditions, rigid ideologies gain traction—not just on the right, but across the spectrum. What matters is not left vs. right, but open vs. closed.

You can see this shift across recent history:

• In the 1960s, economic abundance fueled expansive liberal movements—from civil rights to environmentalism to space exploration.
• By the 1980s and 1990s, as economic anxiety grew, political rhetoric turned toward punishment, deregulation, and moral panic.
• After 2008, the ideological temperature spiked. Populist movements surged. Trust collapsed. Conspiracy theories flourished, not because people were ignorant, but because they were desperate for control.

While this framework uses U.S. history as its anchor, the underlying mechanisms—economic stress, cognitive rigidity, ideological polarization—are not uniquely American. They may be manifesting globally, especially in a world increasingly bound together by information, finance, and crisis.

In such climates, fear narratives and conspiracy beliefs often flourish—not simply from ignorance, but as emotional coping mechanisms. Panics about “globalist agendas,” cultural invasions, or deep-state plots tap into the same psychological currents: a desperate need for clarity, control, and simple enemies during times of deep uncertainty.

These dynamics echo in our culture as well—reflected in the books we write, the films we watch, and the stories that resonate. Each Turning leaves fingerprints on our art and entertainment, offering another window into the mood of the age.

Ideology becomes the symptom of a society’s dopamine tone. And once that shift happens, the leaders we choose—and the decisions they make—begin to reflect that chemical mood.

These feedback loops don’t just repeat—they build. Unresolved tensions and institutional shortcuts from one cycle often carry forward, compounding fragility over time. The result is a system more brittle than it appears, especially when stressed by new forms of disruption.

7. Layer Four: Policy, Power, and the Mood of the Moment

We like to think of leaders as shapers of history—but more often, they are expressions of it.

Political leaders don’t rise in a vacuum. They reflect the emotional climate of their time, channeling the public’s mood—sometimes skillfully, sometimes manipulatively. And because they hold power, their decisions can amplify that mood, for better or worse.

In times of high dopamine and economic optimism, we tend to elect builders: leaders who invest in infrastructure, expand rights, and try to lift everyone. Think Roosevelt after the Great Depression. Eisenhower during the postwar boom. Even Obama, whose message of hope resonated after the 2008 crash—until the system proved more resistant than expected.

But in low-trust, low-dopamine eras, we often reach for breakers: leaders who promise control, scapegoats, or revenge. They don’t rise because they’re persuasive. They rise because they mirror the desperation of a population that feels betrayed and unseen.

These leaders often succeed not despite their cruelty, but because of it. Societies under stress are drawn to figures who reject empathy, who treat negotiation as weakness, and who seem willing to “do what it takes” without flinching. The strongest followers don’t just tolerate this behavior—they celebrate it. Cruelty becomes a performance of strength, and the leader’s lack of empathy is mistaken for clarity or courage. History has seen this before, from industrial tycoons to political demagogues. It is not new—but it is dangerous, because what looks like control often accelerates collapse.

Their policies tend to follow suit:

• Public goods are gutted instead of invested in.
• Institutions are attacked rather than strengthened.
• Policy becomes reactive, tribal, and theatrical—feeding the crisis instead of resolving it

It’s tempting to blame individuals, but the deeper truth is systemic. As Einstein himself said, “the world won’t be destroyed by those who do evil, but by those who watch and do nothing.” And ironically, even Einstein himself may not have become Einstein without the world being ready for someone like him. If it hadn’t been him in 1905, it would’ve been someone else by 1915. Societies produce the leaders they are primed to need—scientists, reformers, or demagogues—based on the emotional and material conditions already in place.

And when those leaders make decisions under stress, those decisions reshape not just laws—but trust. That’s when institutions begin to bend—or break.

8. Layer Five: Institutions—The Breakers or Buffers of the Cycle

Institutions are supposed to steady the ship. At their best, they channel society’s energy into productive action: education systems that prepare the next generation, public health that cushions crisis, journalism that informs, courts that hold power accountable.

But institutions don’t run on autopilot. They depend on trust, on leadership, on participation. When economic pressure and ideological rigidity rise—when dopamine falls and fear takes hold—institutions begin to bend. And under enough pressure, they break.

Sometimes that pressure is internal: underfunding, corruption, or partisan rot. Sometimes it’s external: leaders deliberately undermining public trust for political gain. Often, it’s both.

What matters is this: as institutions weaken, they stop moderating the cycle and start amplifying it

• A justice system that’s seen as rigged encourages vigilante thinking.
• A press that chases clicks over clarity deepens outrage and confusion.
• A government that fails to respond to crisis erodes the belief that anyone is steering the ship.

Weak institutions make low-trust environments feel permanent—and that drags the cycle further down. But strong institutions can absorb shock, preserve empathy, and dampen the volatility that otherwise defines Crisis periods.

They can’t prevent the wave—but they can stop it from crashing as hard.

9. Closing the Loop: The Feedback Cycle of History

We’ve followed five layers—from economic shocks to brain chemistry, ideology, leadership, and institutional strength. On their own, each is powerful. But together, they form a closed feedback loop, where each part reinforces the next.

It works like this:

1. Economic & Social Conditions rise or fall.
2. These shifts influence dopamine tone at the population level—changing how people feel, think, and relate.
3. That mood drives collective ideological behavior: openness vs. rigidity, trust vs. fear.
4. Those behaviors influence the leaders we elevate and the policies they choose.
5. Those decisions either strengthen or weaken our institutions, which then shape the next round of economic outcomes

And back we go.

This is not just a cycle—it’s a system. A multi-level loop. A kind of circuitry that operates beneath the surface of Strauss and Howe’s Four Turnings.

Just as in software, where stopgap patches accumulate into brittle technical debt, so too do societies inherit unresolved solutions from past Crises. These “legacy fixes” may stabilize one era but quietly erode the next—until accumulated strain overwhelms the system again.

Mapping the Loop onto the Turnings:

• High (Post-Crisis Rebuilding): Economic optimism → high dopamine → social trust and empathy →institution building → liberal openness → long-term planning.
• Awakening (Ideological Upheaval): Sustained abundance → dopamine shifts from security to self-expression → generational rebellion → weakened institutions via disillusionment or neglect.
• Unraveling (Fragmentation): Inequality rises → dopamine stratifies (high for elites, low for most)→ polarization, cynicism, and addiction → populist leaders and punitive policy → institutional decay.
• Crisis (Collapse and Realignment): Widespread stress and fear → dopamine bottoms out, cortisol surges → tribalism, rigidity, scapegoating → cognitive overload and vigilance fatigue → institutions fail when needed most → a new economic system must emerge.

This isn’t fate. It’s momentum. The loop can spin smoothly—or spiral violently—depending on how we manage each layer.

But even if we can buffer the system or recognize the signals in time, there’s a deeper question we still have to answer: why does the cycle keep resetting in the first place, even when we see it coming? To explore that, we need to look not just at systems, but at psychology.

Cortisol and Me
I’ve noticed this in myself. Even when I feel intellectually grounded, I still find my attention fraying. I’ll open a tab to work on something meaningful—and wind up watching a YouTube video instead. This isn’t laziness. It’s my brain, adapting to stress by seeking easy rewards and dodging ambiguity. If this model is correct, then we’re not just thinking differently—we’re being re-wired by the world we live in.

9.1 – The Perpetuation of the Cycle

If the loop is so clear—economics shapes dopamine, dopamine shapes ideology, ideology shapes leadership, leadership shapes institutions, institutions in turn shape economic conditions, then why can’t we stop it? Why does the cycle continue, even when we see it coming?

The answer may lie not in our institutions, but in ourselves.

When a society enters a Crisis Turning, the need for collective action becomes urgent. Institutions are faltering, trust is low, and critical decisions loom. Yet paradoxically, this is often the moment when large numbers of people disengage. They stop voting. They stop organizing. They stop believing that anything can change. This mass withdrawal isn’t just political, it’s psychological. And it may be the most important reason the cycle resets.

The very people most capable of helping society navigate the Crisis, empathetic, conscientious, community-oriented individuals, are also the most likely to be overwhelmed by the very stress the Crisis generates. Elevated cortisol levels narrow their focus, erode their sense of agency, and push them into retreat. They’re not apathetic. They’re overloaded. Their disengagement is not a failure of will, it’s a biological coping mechanism.

This creates a devastating mismatch of timing. We need people to override their stress responses just when those responses are most overwhelming. We need them to lean in just when they most want to pull back. If they don’t, the system tips, not because of bad actors alone, but because the good actors stayed home.

This may be the reason the cycle repeats.

This isn’t to say that disengagement is the only force at work. Structural inequality, elite capture, and institutional decay all contribute. But when empathetic participants retreat, those forces face less resistance, and become self-reinforcing.

It’s not just external pressures or elite sabotage. It’s a deeper flaw in the wiring of mass democracy under stress: the very people who could stabilize the system exit the field right when they’re most needed. That exit creates a vacuum, and vacuums don’t stay empty for long. Into that space flow opportunists, demagogues, and parasites who are less constrained by empathy and more willing to seize control.

This pattern isn’t universal, but it’s consistent enough to shape history.

To understand it more clearly, we can map how different types of individuals respond to stress, and how their behaviors affect long-term civic outcomes:

Figure 3: Social Orientation Spectum

This isn’t just sociology, it’s neurology. Stress chemistry drives behavioral patterns at population scale. And if too many Group-Aligned individuals become Disengagers, the feedback loop tilts toward collapse, not reform.

The chart also suggests why this problem is so hard to solve: it’s not that no one wants to help, it’s that the helpers are burning out. They’re not missing in action because they don’t care. They’re missing because they cared too much, for too long, without support, and their brains flipped into self-protection mode.

To soften the Turnings, to prevent the cycle from resetting in the harshest way, we’ll need to solve this problem. We’ll need to build systems, stories, and scaffolding that help people stay engaged even when every instinct says to retreat.

That may be the most difficult task of all.
But if we can’t solve it, the cycle will continue.

And even when Disengagers return, after the cortisol ebbs, after the chaos cools, it may be too late. The world has already shifted without their input. Institutions may have been restructured, norms rewritten, and coalitions formed in their absence. When they reengage, they don’t feel empowered. They feel disoriented. Alienated. Sometimes even betrayed.

That reentry can trigger its own reaction. Instead of stabilizing the new order, they may reject it, fueling backlash, nostalgia, or revolt. They say, “We didn’t vote for this,” even if they literally didn’t vote. In that moment, their long silence becomes a political force, not through action, but through the timing of their return. And that force, however well-intended, can help launch the next Turning.

10. Can We Soften the Cycle?

We can’t escape the wave. But maybe we can smooth it.

The generational Turnings described by Strauss and Howe aren’t laws of nature—but they do describe something deeply human. Our societies, like our bodies, go through phases of expansion and contraction, confidence and doubt. And if the model in this article is right—if our economic systems influence our brain chemistry, which in turn shapes our politics and institutions—then the cycle isn’t just historical. It’s biological. It’s emotional.

That doesn’t make it hopeless. It makes it knowable.

We don’t need to stop the cycle to make progress. What we need is to find the points of leverage—places where a small intervention could change the tone of a generation.

Some possibilities:

• Economic buffering: Policies that reduce chronic insecurity—like universal healthcare, housing stability, or basic income—can prevent mass dopamine collapse.
• Empathy as infrastructure: Treat social trust as a public good, not a luxury. Fund schools that teach perspective-taking. Promote restorative justice over retribution.
• Strengthen institutions early: Don’t wait for the Crisis to hit. Rebuild transparency, accountability, and civic trust before things break.
• Recognize the midpoints: Every Turning has a moment where the mood shifts. If we can see those coming, we might steer—not the wave itself, but how hard it crashes
• Prevent what we might call Reentry Shock. When Disengagers return after the peak of the Crisis, they often find a world that no longer feels like theirs, one they didn’t help shape. That disorientation can turn into rejection, even rebellion. To soften the cycle, we’ll need ways to keep people partially engaged even when they can’t fully engage, whether through low-stakes civic scaffolds, stress-aware communication, or systems that welcome reentry with clarity instead of confusion.

If history moves in pulses of fear and hope, then the task isn’t to flatten the line—it’s to preserve empathy through the troughs, and extend wisdom through the peaks.

Recognizing these patterns is only the first step. If the circuitry is real, then the next challenge is architectural: how might we redesign our institutions—not to escape the cycle entirely, but to soften its extremes and lengthen its arcs? That work begins where this framework leaves off.

The future will always bring another Turning. The question is: what kind of people will be standing when it comes?
