The Evolutionary Foundations of Loyalty, National Cohesion, and America’s Crisis of Coalition Identity
How Elite Ideology, Naïveté, and Coalition Misjudgment have Eroded National Loyalty
Introduction: Values as Revealed Commitments, Not Slogans
American public life is full of references to “values.” Schools publish lists of them, corporations celebrate them, political movements claim them, and the military codifies them in the well-known set of Army Values. But whether we are speaking of a Soldier or a civilian, a society or an individual, values are not what we say they are. They are what our actions reveal we truly place value upon. Economists call these “revealed preferences.” Anthropology describes them as “lived norms.” In ordinary language, they are simply what we prove we care about when it costs us something.
The problem in modern America is that publicly stated values have increasingly taken on the character of platitudes, statements affirmed out of habit or social expectation, detached from the lived commitments they demand. People can repeat words like loyalty, duty, or community while living in ways that demonstrate radically different priorities. Institutions, including the Army, sometimes reinforce this problem by presenting values as lists to memorize rather than deep obligations to understand.
The Army’s values are particularly illustrative because, unlike corporate slogans, they must be lived under danger. Combat exposes whether a Soldier’s values are real or rhetorical. Fear, hardship, exhaustion, and moral pressure strip away pretense. Under those conditions, only values that are deeply internalized, values supported by emotion, instinct, and identity, survive.
Among the Army Values, loyalty stands out because it connects directly to the founding principles of the United States. The Army asks its members to bear true faith and allegiance to the Constitution, a remarkable demand in world history. Soldiers are asked to risk their lives not for a monarch, tribe, kin group, or religious authority, but for a written framework of principles and laws binding together a vast, diverse population. Yet loyalty to an abstraction cannot be sustained merely by reciting a definition. It must be anchored in the deeper psychological machinery of human coalition-building

This point matters far beyond the military. The recent shooting of two National Guard soldiers in Washington, D.C. by an Afghan national brought to the United States after the fall of Kabul forces us to confront how deeply the American public misunderstands loyalty, its origins, its limits, and the biological conditions required for it to flourish. The reason tens of thousands of Afghans were admitted to the United States was not a carefully reasoned assessment of coalition psychology; it was a felt sense of loyalty by American service members who fought beside them. But feelings of loyalty formed under wartime pressure do not automatically translate into enduring allegiance inside a peaceful domestic society.
America has been making this mistake for half a century, repeatedly extending loyalty to foreign partner forces after losing wars fought on their soil. This practice rests on a profound misunderstanding of human nature, one shared across the American foreign policy establishment, particularly by neo-conservative theorists who believed that democracy and market capitalism could transform societies whose social structures, values, and identities evolved under entirely different pressures.
If Americans, Soldiers and civilians alike, wish to recover meaningful national loyalty, we must begin by understanding what loyalty actually is, where it comes from, and why our modern assumptions about it are so badly misaligned with human psychology.
The Evolutionary Origins of Loyalty
Predation, Fighting Back, and the Birth of Moral Coalitions
Loyalty did not begin as a cultural invention or a philosophical ideal. Its origins lie in the earliest survival strategies shaped by predation. Yet not all survival strategies produce the psychology of loyalty. Many organisms survive by blending into the herd, escaping danger through anonymity or scattering when a predator approaches. Species such as antelope, sheep, or shoaling fish form aggregations, but these groupings do not constitute coalitions. They are defensive formations without obligations; when danger strikes, individuals flee independently. No member intentionally accepts risk for another. Evolution favors self-preservation, not sacrifice.
Anthropologists and evolutionary biologists note that this form of “group living” does not generate the emotional architecture necessary for what humans call morality or loyalty. As Hamilton’s (1971) selfish herd model demonstrates, such aggregations emerge from individuals reducing their own predation risk, not from feelings of mutual responsibility or coalition membership.
By contrast, morality and loyalty emerged from species that fight back. In species that engage in coordinated defense or offense, individuals incur personal risk to protect other members of the group. These are the species in which the evolutionary ingredients of loyalty, honor, and duty first appear.
Cape buffalo will charge lions to protect a calf that is not their own. Predator coalition forming species such as Wolves and Chimpanzees, add to this. They both defend and expand their territories as coordinated packs, engaging in organized violence against rival groups, conducting border patrols and lethal intergroup raids (Wrangham, 1999). These behaviors require trust, memory for past support, and punishment of defectors. These animals do not scatter like prey herds; they organize and retaliate.
In such species, natural selection begins to favor psychological traits that support coalitional cohesion:
reciprocal obligation,
the expectation of mutual aid,
emotional bonding under shared threat,
shame and punishment for defection,
reward for loyalty and bravery,
and attentional biases toward those who stand and fight beside them.
Tooby and Cosmides (2010) describe these as the cognitive foundations of “coalitionary psychology,” noting that they arise specifically under conditions in which coordinated danger response is critical for survival.
In this sense, the earliest moral organisms were not the gentlest or most submissive. They were the species that stood and fought together, the ones that developed the capacity to incur personal cost for the group’s benefit. Morality evolves not from avoidance but from confrontation, shared danger, shared fate, and collective violence used to defend or advance the coalition.
From Fighting Coalitions to Human Loyalty
Humans extend this coalitional heritage to an extraordinary degree. We wage war in coordinated units, defend territories, and maintain alliances through complex social norms. But this required not only cognition, it required an emotional system capable of sustaining loyalty across time, danger, and distance.
Thus the neurochemical systems that anchor human loyalty, oxytocin-mediated bonding, opioid-based social reward, and dopaminergic reinforcement, did not evolve for “niceness.” They evolved to maintain cohesion in fighting groups, where survival depended on coordination, trust, and mutual defense (De Dreu et al., 2011; Machin & Dunbar, 2011).
These mechanisms created the psychological architecture later elaborated into honor, duty, courage, and national identity. Loyalty is ancient, powerful, and deeply rooted in the biology of coalitionary violence. But because it evolved under very specific conditions, it is also fragile. It requires:
clear coalition boundaries,
shared danger,
mutual dependence, and
the punishment of betrayal.
When those conditions weaken, as in modern, safe, affluent societies, loyalty becomes unstable. When they collapse, loyalty dissolves altogether.
The Neurochemistry of Coalition Bonds
Loyalty is not merely cognitive; it is neurochemical. Oxytocin increases trust toward in-group members while intensifying vigilance and aggression toward out-groups (De Dreu et al., 2011). Endogenous opioids reinforce social bonding and shared hardship (Machin & Dunbar, 2011). Dopaminergic pathways encode the reward of coalition success.
These mechanisms evolved because coalitions that stayed together survived. Those that fragmented under stress perished. Loyalty, therefore, is not an abstract virtue, it is a survival strategy shaped by millions of years of violent competition.
Human Coalitions and the Protector Class
Coalition Warfare and Shared Danger
Humans are the only primate species that wage organized, premeditated war at scale (Otterbein, 2004). For most of our evolutionary history as hunter–gatherers, participation in inter-coalition violence was nearly universal among adult males; survival depended on collective defense, and every able-bodied man was part of the fighting strength of the band. A true “protector class” did not yet exist because the demands of subsistence tied every member directly to the group’s survival.
It was only with the advent of agriculture, beginning roughly 12,000 years ago, that large, settled communities emerged, producing food surpluses and enabling social specialization. Some individuals could now devote themselves primarily to tasks other than food gathering, craftsmanship, ritual leadership, administration, and, crucially, warfare. As villages became towns and towns became early states, the scale and stakes of intergroup conflict increased, and societies developed a dedicated protector class: individuals (overwhelmingly men) who specialized in border defense, territorial warfare, and the organized application of violence on behalf of the wider community. This specialization amplified the importance of loyalty, cohesion, and internal moral codes, because these protectors now bore risks on behalf of a population that no longer fought collectively.
Evolution favored cognitive and emotional traits that enhanced group cohesion under danger: reciprocal obligation, honor, shame, memory for betrayal, and a bias toward those who risked themselves for the coalition (Tiger & Fox, 1971). In every traditional society, warriors hold elevated moral status not because of ideology but because the coalition’s survival depends on them.
Modern Safety and the Collapse of Visible Dependence
In modern America, most citizens live in unprecedented safety. Predators are gone; raiding parties do not descend upon neighborhoods; soldiers patrol far from home. The protector class still exists, U.S. Soldiers, Marines, Sailors, Airmen, but most citizens rarely see them operating in contexts of real danger.
The human nervous system, evolved to feel loyalty when dependence is felt, does not respond to invisible threats. As a result, national loyalty weakens. Civilians cease to feel bonded to the protectors. The protector class becomes socially distant. Shared hardship disappears, removing the conditions under which loyalty naturally arises.
This is not a moral failure, it is an evolutionary mismatch.
America’s Eroding National Loyalty
Coalition Boundaries in Modern States
Loyalty depends on clear coalition boundaries: who is “us” and who is “them.” These boundaries determine obligation, trust, and the willingness to fight or sacrifice (Tooby & Cosmides, 2010).
When boundaries blur, coalitions collapse.
In ancestral environments, boundary collapse was existential. A tribe that misread strangers as safe, or welcomed them without the instinctive caution we now label xenophobia, invited death. Human cognition is therefore wired to be exquisitely sensitive to betrayal, defection, and ambiguous membership.
The American Problem: Boundaries Ignored
In modern America:
Political elites treat coalition membership as ideological, not biological.
The public treats safety as ambient and permanent.
The protector class is culturally segregated.
The nation imports individuals from defeated coalitions without understanding the psychological consequences.
This combination yields declining national loyalty because it violates the ancient logic of coalition maintenance.
Case Study: The Washington, D.C. National Guard Shooting
On November 26, 2025, two West Virginia National Guard soldiers on duty in Washington, D.C., were shot by an Afghan national, Rahmanullah Lakanwal—reportedly a former member of a U.S.-backed partner force who was relocated to the United States after the 2021 withdrawal from Afghanistan.
This incident is a paradigm example of coalition-boundary failure.
Instrumental vs. Identity-Based Cooperation
Partner forces cooperate with the United States instrumentally, because American power temporarily aligns with their survival interests. This is cooperation, not allegiance. Once the mutual threat disappears (e.g., the Taliban’s rise, U.S. withdrawal), their incentives shift. There is no evolutionary reason for their wartime alliance to translate into domestic loyalty.
The assumption that it does is uniquely modern, and uniquely Western.
The Protector Class Pays the Price
The individuals endangered by these misjudgments are not diplomats or policymakers, they are members of the protector class. And unlike elites, these men live inside the ancient psychological architecture that governs risk, trust, and coalition loyalty. When they fight beside allied units, especially in missions built around training and empowering indigenous forces, they form the same deep bonds that ancestral warriors always have. Nowhere is this more evident than in U.S. Special Forces, whose core mission is to embed with local fighters, train them, and then stand shoulder-to-shoulder with them in combat over months or even years. Living, bleeding, and surviving together triggers the full suite of biological mechanisms that evolved to forge loyalty: shared danger, reciprocal sacrifice, coalition interdependence
When political leaders later reverse course, abandon allies, change strategic priorities, or misread the local tribal landscape, the burden of that naiveté falls squarely on the protector class. They are the ones forced to break bonds their nervous systems are wired to honor, and they are the ones who pay the price for elite miscalculations, often in blood, moral injury, or lifelong psychological scars.
Alienation From the Protected Class
This same biological machinery of loyalty also creates a mirror-image reaction at home. Warriors who risk their lives beside foreign partners naturally feel a profound sense of betrayal when members of their own protected class, those who enjoy the safety and prosperity secured by the protector class, show indifference or hostility toward their mission. Our nervous systems evolved in small coalitions where every member understood the necessity of defense and the cost of failure. When modern elites or segments of the civilian population lose touch with that reality, the protector class experiences a deep, visceral moral dissonance.
To fight beside someone in a foreign valley and trust him with your life, only to return home and find fellow citizens who question the legitimacy of the mission, resent the culture of warriors, or fail to grasp the existential function of collective defense, triggers the same ancient circuits that once signaled a breach of coalition integrity. The men who bear the risks instinctively expect reciprocal loyalty from those they protect. When that loyalty is absent, the psychological injury is real, an evolutionary echo of betrayal within the tribe.
The Half-Century Pattern: Importing Defeated Partner Forces
Since the 1970s, the United States has repeatedly brought tens of thousands of partner force members, interpreters, militia affiliates, and their families to America after losing wars fought on their behalf:
Vietnam (1975): South Vietnamese officers and intelligence partners
Somalia (1990s): militia affiliates and clan partners
Iraq (2003–2011): interpreters and members of local security forces
Syria (2010s): Kurdish fighters and militia families
Afghanistan (2021): over 80,000 partner force members, police, and intelligence personnel relocated after defeat
From the standpoint of coalition psychology, this is extraordinary.
No successful warrior society in history—Greek, Roman, Mongol, medieval European, or tribal—ever brought the remnants of a defeated foreign coalition into its own homeland and treated them as immediate, full members of the tribe. When ancient peoples absorbed outsiders at all, it was only under strict conditions: they were either conquered and tightly controlled, or slowly assimilated over generations through intermarriage, military service, and cultural adoption. Coalition boundaries were sacred because survival depended on them. The modern Western instinct, to admit intact, loyalty-bound groups from failed wars directly into the homeland and grant them instant equality, is unprecedented. There is no historical parallel for a victorious society importing foreign coalitions whose primary loyalties were forged elsewhere.
Such a move violates:
the logic of defeat
the logic of coalition boundaries
the logic of cultural cohesion
and the logic of evolved-likelihood assessment of loyalty
America does it because America no longer understands coalition logic.
The Neo-Conservative Error: Universalizing Western Political Psychology
Democracy and Markets as Universal Aspirations
Neo-conservative theory, emerging in the late 20th century, held that liberal democracy and market capitalism were universally desired endpoints of human civilization. Francis Fukuyama’s (1992) “End of History” thesis encapsulated this view: the world was converging toward liberalism.
The foreign policy establishment believed:
Individuals everywhere want self-rule.
Free markets generate peace.
Removing dictators unleashes natural democratic instincts.
Western institutions can override deep cultural differences.
This worldview shaped interventions in Iraq and Afghanistan. U.S. policymakers believed they could dissolve anti-Western violence, and the coalitions behind it, by exporting democracy, education, and economic opportunity. But that high-minded logic was never what the public was told. Instead, Americans were rallied around more concrete and emotionally charged claims: weapons of mass destruction, imminent threats, and the specter of a hostile regime handing nuclear or biological agents to terrorists.
The reliance on these questionable excuses revealed something deeper: the ideological commitment of the policymakers outweighed their commitment to honesty. They believed so completely in their civilizational project that they treated public consent as an obstacle to be managed rather than a trust to be honored, perhaps revealing their lack of loyalty to the common citizen. These arguments were effective precisely because they concealed the deeper neo-conservative ambition, the belief that transforming foreign societies was both possible and morally obligatory. Most citizens, and even many soldiers, still default to those public justifications today, unaware of the elite motivations and assumptions driving the wars they were asked to fight.
Anthropologically, This Was False
This worldview was not grounded in anthropology or evolutionary psychology; it was grounded in Western secular optimism, and in a kind of civilizational hubris. It assumed that Western political ideals, such as human rights and democracy, were universal aspirations rather than cultural products spread historically through power, conquest, and coercion. From this conceit flowed a belief that other societies would naturally embrace these values once exposed to them. It assumed that:
individual autonomy is universal
clan-based social organization is obsolete
religion is not a totalizing political system
liberal norms can displace honor-based cultures
But Islam is not merely a religion. It is a civilizational order with its own legal, moral, and political architecture. Tribal identity remains primary across Afghanistan and large portions of the Middle East. Kinship, honor, and religious duty outweigh democratic norms in organizing social behavior (Atran, 2010).
The Result: A Catastrophic Misreading of Human Nature
Neo-conservative universalism represents a profound failure to understand the diversity of evolved human psychologies. Coalition loyalty, identity, moral obligation, and political legitimacy vary dramatically across societies. The assumption that Western norms can be mailed into foreign populations, at gunpoint or through development programs, is historically unsupported.
The same naïveté drove both:
the attempt to impose Western democracy in Islamic societies, and
the assumption that partner forces would become loyal Americans once relocated.
Both rested on a false belief in universal Western-style psychology.
Why These Errors Undermine National Loyalty
A Coalition That Cannot Define Its Boundaries Cannot Inspire Loyalty
Humans evolved to invest loyalty in coalitions that:
face real danger
maintain clear boundaries
reward sacrifice
punish betrayal
share hardship
and demonstrate internal coherence
Modern America satisfies almost none of these conditions.
Civilians see no danger.
Boundaries are ideological rather than functional.
Sacrifice is invisible.
Betrayal is tolerated.
Shared hardship is nonexistent.
Cohesion is eroding.
Meanwhile, the protector class still inhabits the ancient logic of survival and coalition warfare. Their loyalties are shaped by shared danger, hardship, and the bonds forged under threat—forces far older than any modern ideology. As this happens, the wider society is fragmenting in ways that weaken the very concept of a shared coalition. Some elites no longer feel any obligation to the common people who fill the ranks of the protector class; they do not send their own children to serve, and they no longer experience national defense as a reciprocal duty. At the same time, cultural and ethnic subgroups increasingly direct their primary loyalties inward—toward their own identity groups, rather than toward the nation as a whole. Historically oppressed minorities do this for understandable reasons; now an increasingly large sub-group of the once-dominant majority are beginning to do the same in reaction. The result is a widening chasm: a protector class whose loyalty is forged in blood and danger, and a civilian coalition whose internal divisions threaten the very notion of a unified coalition. In such conditions, the protector class may begin redirecting its loyalty away from the national whole and toward its own sub-coalitions, a shift that history shows is difficult to reverse.
The Final Contradiction
America behaves as if it is:
a victorious superpower with global allies, and simultaneously
a defeated coalition importing the remnants of failed wars into its homeland.
This contradiction violates the basic principles of coalition psychology. But the problem is not immigration itself. Some groups join the American coalition, adopt its civic identity, and ultimately strengthen it. Former South Vietnamese allies are the clearest case: they fought beside American forces, admired American institutions, and arrived prepared to embrace constitutional government, mutual freedom, representative law, and the idea that governments derive “their just powers from the consent of the governed.”
Other groups, however, come from worlds where legitimate authority flows not from free citizens but from lineage, sect, or sacred law, deep, ancient forms of loyalty that do not dissolve upon crossing a border.
Yet a growing portion of our own society has convinced itself that loyalty, to the nation, to the Constitution, to the coalition that protects their freedoms, is not only unnecessary but regressive. They treat borders as arbitrary lines, citizenship as a mere formality, and the very idea of a defined American people as an immoral relic. They reject the notion that citizens have any collective right to decide who may join their coalition.
And from within that worldview, they eagerly invite in groups whose internal loyalties, to kin, sect, clan, or tribe, are far stronger than any allegiance they can immediately feel toward an abstract constitutional nation they have just entered. These loyalties are not malicious. They are adaptive strategies for survival in environments where the state was weak, factional conflict was constant, and trust flowed inward rather than outward.
But no coalition can survive this contradiction:
a native elite that denies the legitimacy of loyalty and boundaries, combined with incoming groups whose loyalties are intense, cohesive, and often incompatible with American civic identity.
History shows that coalitions fragment when their members no longer share the same foundational commitments.
The American coalition is held together by something specific and historically fragile:
loyalty to the Constitution and the ideas it encodes, mutually supported freedom, representative law, and the principle that legitimacy arises from the consent of the governed.
These ideals do not emerge naturally. They must be learned, internalized, and defended.
When parts of the population abandon these civic loyalties, while other parts arrive with loyalties that compete with or override them, the coalition’s coherence erodes.
And when citizens no longer believe they have the right or responsibility to maintain the boundary of their own coalition, they cease being a coalition at all.
Conclusion
Loyalty evolved under conditions of danger, dependence, shared hardship, and clear coalition boundaries. Modern America, insulated from danger and governed by ideological universalism rather than evolutionary realism, has lost the conditions that generate loyalty. The result is a society where the protector class remains loyal to a coalition that no longer remembers what loyalty requires.
The Washington, D.C. shooting was not an isolated tragedy, it was a symptom of a broader civilizational naïveté. For half a century, the United States has misunderstood the nature of human loyalty, misread its partners, universalized its own values, and imported defeated allies into its domestic population under the assumption that shared danger abroad translates into shared identity at home.
It does not.
It never has.
Evolution did not build us that way.
In Dante’s Inferno, the worst region of Hell, the frozen floor of the Ninth Circle, is reserved for betrayers. Not murderers, not tyrants, not the wrathful or the proud, but those who violate the bonds of trust that hold a community together. Dante intuited something our evolutionary history confirms: betrayal is the ultimate moral crime because it dissolves the coalition on which survival depends.
When a society loses the ability to define its coalition, when it abandons the obligations of reciprocity, when it treats loyalty as optional and boundaries as outdated, it drifts toward the same moral vacuum Dante imagined in ice. A nation can withstand danger, hardship, poverty, and war. What it cannot withstand is the quiet corrosion of loyalty, between citizens, between classes, between the protector class and the people they defend.
A nation that ignores the biology of loyalty will eventually discover that loyalty has laws older than states, older than armies, older than civilization itself.

Outstanding writing/analysis of a complex topic, Matt! 👏 I also find the evolution paradigm very clarifying about which virtues and values humans embrace across time and culture. You might enjoy Seligman & Peterson’s analysis of all that in their book which I reference in this essay:
https://open.substack.com/pub/bairdbrightman/p/what-is-a-good-person?utm_campaign=post&utm_medium=web
Which values are expressed in action (rather than just preached in words) has a lot to do with what behaviors the environmental conditions reward and reinforce. When the most “successful” and admired people in a culture are mostly narcissists and charlatans, many people take notice and act accordingly.
Another great post. This comment really struck me: “…importing the remnants of failed wars into its homeland.” What if the importation is not due to naivety, but intentionality? What if the Regime did the research and figured this out long before you did, and thus imported the “remnants of failed wars” with the intention to produce exactly the results it’s produced? Unanswered questions that lead me to ask if it was intentional include, 1) The murderer worked with the CIA in Afghanistan; does he still have CIA connections? 2) How did he get 2500 miles from Washington State to D.C. with a handgun? 3) Where did he get the handgun? 4) Given what he learned in the Zero Units in his homeland, did he stake out / recon the pattern of his victims? 5) Where did he stay & how was he supported in DC? 6) Did someone (CIA?) use knowledge of Islam to convince the murderer that if he died killing an infidel he would get instant atonement for his failure to be a good Muslim? I’m very troubled that this whole event goes much deeper than an “Afghan war vet with PTSD.” Anyway, thanks for all the research and thought you invested in this post.
