4.3 Aggression, status, and dominance

Aggression is not a senseless drive but a strategy — costly and dangerous, deployed when its expected payoff exceeded its expected cost. Understanding when it pays clarifies the patterns of human violence.

Aggression as strategy

Selection would never favor indiscriminate violence; fighting risks injury and death. Instead it favors conditional aggression, calibrated to context: the value of the contested resource, the probability of winning, and the costs of losing. Animals (and people) assess these factors and usually settle conflicts through displays and assessment rather than escalating to combat.

The young male syndrome

Daly and Wilson described the young male syndrome: risk-taking and violence peak in young men, precisely the demographic that historically faced the fiercest competition for status and mates and had the least to lose. Homicide statistics across virtually every society show the same age-sex signature — a curve that bends sharply upward in young adulthood for men.

Status and dominance vs. prestige

Humans pursue rank through two routes. Dominance is status taken by force and intimidation; prestige is status freely conferred because of valued skills or knowledge. Both raise reproductive prospects, but prestige is the distinctively human route, built on the value others place on learning from the skilled.

A grounding example

Daly and Wilson analyzed homicides and found that a large share of male-male killings arose from seemingly "trivial" altercations — insults, status challenges, disputes over face in front of others. To an outsider the stakes look absurdly small. But in the ancestral world, a reputation for not tolerating disrespect deterred future exploitation, and status translated into mating opportunity. The "trivial" trigger is a status contest, and status was anything but trivial for a young man's reproductive future.
