The Male-Warrior Hypothesis

> Synthesis layer. This page is the brain. The full extracted text lives at inbox/zotero-articles/JSCWQNGT. Rob Henderson's essay on the male-warrior hypothesis — the claim that human males evolved to coordinate aggression against outgroups while suppressing within-group hostility, and that this coalitional psychology is distinct from (and more developed in) males.

The meta-take: this is the framework that explains why men compete violently with rivals but cooperate violently with allies, and why women's intergroup psychology is qualitatively different (fear-and-avoidance, not coalition-formation). The male-bonding-through-insult pattern is the cleanest behavioral signature.

Why it matters: the hypothesis is the missing link between dominance/prestige (status) and the modern "male friendships are looser but more activated" observation.
