# Dominance Hierarchies **The actual primatology of social rank**, as opposed to the cartoon version popularized in self-help, pickup-artistry, and the [[Intellectual Dark Web]]-adjacent political ecosystem. This page exists for two reasons: first, to document what working primatologists like [[Robert Sapolsky]] and Frans de Waal actually find when they spend decades measuring dominance in wild populations; second, to make the case against [[Jordan Peterson]]'s "lobster hierarchy" argument — a politically influential misuse of biology that has been criticized by Sapolsky and many others. ## The basic concept A dominance hierarchy is a stable pattern of competitive outcomes in a social group: individual A consistently displaces, gets priority over, or wins agonistic encounters with individual B. The pattern was first formally described in chickens (Schjelderup-Ebbe, 1921 — the original "pecking order"), then extended across vertebrates. Hierarchies vary along several dimensions: - **Linear vs. non-linear** — strict pecking orders (A>B>C>D) vs. networks with intransitive relationships - **Steep vs. shallow** — large vs. small fitness consequences of rank - **Stable vs. unstable** — whether ranks shift frequently - **Despotic vs. egalitarian** — winner-take-all vs. distributed - **Sex-based, age-based, kin-based** — multiple organizing axes The political payload of "hierarchies exist" depends entirely on *which kind*, *under what circumstances*, and *with what relevance to humans*. ## What real primatology finds Several findings from decades of field work routinely surprise lay audiences who absorbed the alpha-male story from popular media. ### 1. Pair-bonding vs. tournament species — humans are not chimps Primates fall along a spectrum: - **Tournament species** (baboons, gorillas, chimps) — pronounced sexual dimorphism (males much larger than females), high male-male competition, polygynous mating, steep dominance hierarchies - **Pair-bonding species** (marmosets, titi monkeys, owl monkeys, gibbons) — minimal sexual dimorphism, low male-male competition, monogamous or quasi-monogamous mating, shallow hierarchies **Humans sit in the middle, closer to the pair-bonding end on most metrics** (modest dimorphism, mostly biparental investment, mostly socially monogamous). [[Behave]] devotes substantial space to this point. The popular "alpha-male" frame imports a tournament-species template onto a species that did not evolve as a tournament species. ### 2. Dominance is mostly social, not violent Across long-term studies of chimps (de Waal), bonobos (Hare), baboons (Sapolsky, Cheney/Seyfarth), the alpha is usually the individual with the strongest *coalitions, grooming networks, and reciprocity history* — not the largest or most aggressive. De Waal's *Chimpanzee Politics* (1982) documented coalitional politics in detail: alphas who tried to maintain position through pure violence were typically overthrown by lower-ranking coalitions. Bonobos, our other closest relative, have female-dominated social structures with extensive sex-based conflict resolution. The cartoon "the strongest male wins by fighting" applies to almost no actual primate species. ### 3. Subordinates pay biological costs — see [[HPA Axis]] Sapolsky's contribution to the literature: low-ranking individuals in *stable* hierarchies experience chronic harassment, low control, low predictability, and few outlets — the textbook profile of pathogenic stress. The result is measurable health damage. Importantly, this means hierarchies aren't *just* differential access to resources; they impose direct biological costs on the subordinate body. See [[HPA Axis]] for the full mechanism. ### 4. Culture transmits, hierarchies can change The [[Forest Troop Study]] (Sapolsky and Share, *PLOS Biology* 2004) documented a savanna-baboon troop in which the most aggressive males died off in a tuberculosis outbreak. The remaining troop developed a less-violent culture characterized by high rates of male-female grooming, relaxed hierarchies, and lower subordinate stress. **The culture persisted across more than a decade** as new males immigrated in and adopted the troop's norms. This is direct evidence that even in a "tournament species," hierarchical patterns are partly cultural and can be remade. ### 5. Multiple hierarchies, not one Even within a single primate group, dominance is rank-specific to the resource or context. The chimp who controls access to a food patch may not be the same chimp who controls mating opportunities, who may not be the same chimp coalitions defer to in conflicts. The "alpha" abstraction collapses what is actually several overlapping, partially independent hierarchies into a single fictional summary statistic. David Mech, the wolf biologist who coined the "alpha wolf" terminology in the 1970s, **publicly retracted the alpha framing** for wild wolves in 1999, noting that wild wolf packs are family units led by breeding pairs (parents), not by combat-victorious dominants. ## The Jordan Peterson "lobster" argument The most politically influential misuse of dominance-hierarchy biology in the past decade is [[Jordan Peterson]]'s opening chapter of *12 Rules for Life* (2018), which uses lobster serotonin as a model for human social hierarchy. The summary of the argument: 1. Lobsters live in dominance hierarchies. 2. Lobster serotonin responses change based on dominance position. 3. Humans also have a serotonin system. 4. Therefore dominance hierarchies are deep evolutionary inheritances, neurochemically inscribed, and predate the human nervous system. 5. Therefore opposing social hierarchy is opposing nature itself. ### Why this fails as biology [[Robert Sapolsky]] and other working biologists have publicly criticized the argument on several grounds: **The phylogenetic gap is enormous.** Humans and lobsters last shared a common ancestor over **500 million years ago**, before the Cambrian explosion. The shared serotonergic biology at that distance is so generic — almost every animal with a nervous system uses serotonin for *something* — that it carries no inferential weight about specifically *human* social organization. You could equally argue that humans should mate via broadcast spawning because we share serotonin with fish. **The lobster hierarchy is not the kind of hierarchy under political dispute.** Lobster dominance interactions are dyadic combat events with neurochemical aftermath. Human political hierarchy is institutional, hereditary, legal, and rich with cooperative-coalitional structure. The two phenomena share a label, not a mechanism. **The serotonin-rank correlation in lobsters is also true in many primates — and points in the opposite direction.** In several primate studies, serotonin levels correlate with *prosocial* and *coalition-maintaining* behaviors more than with aggressive dominance. The neurochemistry doesn't underwrite a "fight your way to the top" story even within mammals. **The naturalistic fallacy.** Even if hierarchies were deep evolutionary inheritances, this would not entail that any particular human hierarchy is morally legitimate or politically untouchable. "It is natural" does not entail "it is good" or "it should be preserved." Philosophers identified this fallacy at least as far back as Hume; biologists writing for the public regularly slide past it. **The cherry-pick.** Lobsters and other crustaceans are an unusual model for human social behavior — they have decentralized nervous systems, no parental investment to speak of, and indeterminate growth. If the argument were really biological rather than political, the obvious models would be other primates, which (as above) tell a much more complicated and less consoling story. ### Why the argument has political traction anyway The argument is doing political work, not biological work. It gives a science-flavored cover to a particular conservative intuition: that **hierarchy is natural and immutable, and progressive opposition to it is therefore irrational rebellion against reality**. The lobster is interchangeable with any other prop; the conclusion was the goal. Sapolsky has made this point in multiple interviews, treating the lobster argument as an example of how popular self-help authors weaponize selective biology to validate their political priors. ## Adjacent ecosystem pages - [[Jordan Peterson]] — the person page - [[Intellectual Dark Web]] — the broader ecosystem that amplified the lobster argument - [[HPA Axis]] — what subordination actually does, biologically - [[Forest Troop Study]] — counter-evidence that hierarchies are remakeable - [[Robert Sapolsky]] — the working primatologist who has rebutted the lobster argument publicly - [[Behave]] — the synthesis text on humans-as-intermediate primates ## See also - [[Psychology]] — subject hub - [[Authoritarianism]] — adjacent literature on political dominance preferences (SDO, RWA) - [[Determinism]] — Sapolsky's larger frame
