Societal and Cultural Trauma
The Biological Baseline: Animals Don't Kill Their Own Kind
Before the argument about collective trauma can be made, it needs biological grounding. Levine provides it through ethology: the observation that most animals, despite powerful evolutionary imperatives toward aggression within their species, have evolved ritualized behaviors that prevent mortal injury to members of their own species.
Male deer lock antlers — a wrestling match for dominance, not a duel to the death. When one establishes superiority, the other leaves. Dogs and wolves bite to wound, not to kill, within species. Rattlesnakes butt heads with each other; piranhas fight each other with tail-lashing rather than teeth. The most lethally equipped animals do not deploy their lethal equipment against their own kind. Submissive posturing — rolling onto the back to expose the belly — is universally recognized across species as a signal that terminates aggression; the signal is honored even by the victor who could easily press the advantage.1
These are not accidents of evolution. They reflect a clear evolutionary advantage: intra-species killing undermines the group and the species. Ritualized aggression establishes dominance hierarchies and reproductive hierarchies without destroying the social structure that makes the group viable. Killing your competitors reduces the gene pool you are competing within.
Among some human hunter-gatherer cultures, Levine notes, similar ritualized forms of conflict resolution existed: Eskimo communities that settled disputes through wrestling, ear-cuffing, and head-butting. Singing duels — elaborate ceremonial competitions in which songs were composed for the occasion and an audience determined the winner. Some cultures ended skirmishes when a single member was injured or killed, operating under the same intra-species inhibition that prevents wolves from continuing to press a defeated opponent.1
Modern warfare breaks this pattern systematically. Levine's question: what happened? What removed the evolutionary prohibition against killing members of one's own species that appears to be present across the animal kingdom? His answer is not primarily ideological or political — it is traumatological. The mechanism that removes the prohibition is collective trauma's mass re-enactment cycle, described in the section that follows.
[Note: Levine acknowledges this is his most speculative argument. The ethological observations about animal intra-species behavior are empirically grounded; the leap to collective human trauma as the primary mechanism of modern warfare's scale is speculative. Both the evidence and the speculative leap are preserved here.]
The Mass Re-enactment Cycle
If individual trauma produces re-enactment — the organism's compulsive return to the unresolved threat scenario without the discharge that would resolve it — then collective trauma produces collective re-enactment: entire populations caught in behavioral loops driven by undischarged survival energy that was never permitted to complete.
Levine's extension of the individual somatic trauma framework to societal and historical scales is his most speculative territory, and he acknowledges it as such. The mechanism he proposes: traumatized populations carry chronically elevated levels of undischarged arousal. This arousal requires an outlet. When the outlet is not provided through somatic resolution, the population finds external targets that match the internal arousal — enemies whose existence seems to justify and explain the activation the population was carrying before the conflict began. War, in this account, is not primarily the result of ideological difference or territorial ambition. It is the re-enactment mechanism operating at collective scale: the traumatized population seeks an external source for the internal danger they cannot locate or discharge.1
[SPECULATIVE — Levine's most ambitious claim; limited empirical grounding; reductive as a single-cause account of political violence. Hold with significant epistemic caution. See Tensions below.]
The Prescott Research
The most empirically grounded element of Levine's societal argument is his citation of James Prescott's cross-cultural research (1975, published in The Bulletin of the Atomic Scientists). Prescott examined 49 pre-state societies and found a strong negative correlation between rates of physical affection toward infants and levels of adult violence. Societies in which infants received high levels of physical contact, holding, and touch showed significantly lower rates of adult violence, theft, and warfare. Societies with low rates of infant touch showed significantly higher rates of adult violence.1
Levine interprets this through his framework: physical affection toward infants provides the regulatory co-presence (the witnessing, the somatic attunement) that allows the infant's nervous system to complete arousal cycles rather than trapping them. Infants who are touched, held, and rhythmically regulated develop the nervous system's discharge capacity. Infants who are isolated or under-touched develop stuck survival energy patterns early — patterns that then persist into adulthood as chronic arousal without resolution, and which require external outlets.
Prescott's research predates much of current developmental neuroscience and has not been fully replicated in controlled contexts. It is presented here as a plausible mechanism, not established fact. [PLAUSIBLE — needs corroboration; verify Prescott 1975 against subsequent developmental neuroscience]
The Norway Infant-Bonding Work
Levine mentions work by researchers (unnamed in his text as Wedaa, but needing verification) studying infant-mother bonding interventions in Norway — community-based programs that supported early physical bonding, co-regulation, and rhythmic infant care. These programs were associated with reduced rates of social violence in the communities where they operated.1

Rhythm and Movement as Collective Medicine
Levine proposes that the healing mechanism for collective trauma parallels the individual healing mechanism: somatic discharge through rhythm, movement, and communal physical practice. Indigenous cultures — he argues — embedded this mechanism in their collective life through dance, drumming, communal movement rituals, and ceremony. These practices provided regular, culturally sanctioned opportunities for the social nervous system to activate and discharge, preventing the accumulation of trapped arousal that would otherwise require a war to release.1
Modern industrial cultures have systematically eliminated most of these collective somatic discharge mechanisms. The consequences, on Levine's account, are visible in the scale and persistence of modern political violence. This is a sweeping claim with minimal empirical specificity; it is worth holding as a generative hypothesis rather than a demonstrated conclusion.
Tensions
Reductionism: Levine's account of warfare as mass re-enactment of collective trauma is a single-cause explanation for a phenomenon that historians, political scientists, and evolutionary psychologists have documented as multiply determined — resource competition, ideological conflict, in-group/out-group dynamics, leader manipulation of group psychology, territorial logic, and more. Reducing warfare to "undischarged collective arousal seeking an external target" flattens this complexity. The framework may identify a contributing mechanism without having identified the mechanism. [VAULT — not from Levine]
The Bernays/Boot counter-evidence: The vault contains detailed accounts (Boot's Invisible Armies, Bernays's persuasion framework) of how political leaders manufacture consent for violence through active propaganda and manufactured grievance — not through pre-existing traumatic arousal that happens to find a target. These accounts do not require a trauma substrate at all. Both mechanisms may operate simultaneously; neither is sufficient alone.
Prescott's methodology: Cross-cultural correlational research across 49 pre-state societies faces significant methodological challenges (confounding variables, anthropological source quality, causation directionality). The Prescott finding is suggestive, not conclusive. [PLAUSIBLE — needs corroboration]
Cross-Domain Handshakes
Group Psychology and Herd Instinct Doctrine (Psychology) Trotter's herd instinct doctrine and Levine's collective trauma framework offer parallel accounts of why populations become susceptible to violence and mass movement. Trotter's account is evolutionary-social: the logic-proof compartments of herd psychology make populations susceptible to any narrative that promises group cohesion and enemy identification. Levine's account adds a somatic substrate: the arousal that the traumatized population is already carrying makes them actively seek the enemy-identification narrative that Trotter describes as being accepted by susceptible herd-members. Both mechanisms may be necessary together: the herd instinct provides the cognitive susceptibility; the traumatic arousal provides the motivational fuel.
Open Questions
- Is there empirical evidence for the claim that collective somatic discharge practices (dance, drumming, communal movement) reduce rates of political violence in the communities that practice them? What research would test this hypothesis?
- Prescott's finding has a correlation but not a demonstrated mechanism. Does developmental neuroscience support the claim that early touch and co-regulation directly affect adult arousal-discharge capacity in ways that would predict adult violence rates?
- If collective trauma drives re-enactment cycles, what would a collective renegotiation process look like? Is the South African Truth and Reconciliation Commission a candidate? What elements of its design reflect renegotiation-vs-re-enactment logic?
