In tribal warfare among non-state societies, men do not regularly take high lethal risks for the group; pitched battles have few casualties and real combat is by raids and ambushes.

The claim has three parts: (a) men in non-state tribal warfare do not regularly take high lethal risks for the group, (b) pitched battles have few casualties, and (c) most real killing happens through raids and ambushes. True: the ethnographic and archaeological literature as of 2012 supports all three. Mostly true: all three are broadly supported, with a minor overstatement in a detail. Mixed: roughly half of the parts are supported, or the literature is substantially divided. Mostly false: the claim rests on something true, such as raids and ambushes being the dominant form of lethal violence, but distorts it, for example where well-documented studies show men regularly accepting substantial lethal risk for the group. False: the evidence shows that tribal warriors regularly accept high lethal risks and that pitched battles are typically high-casualty.

   “In several instances involving formal primitive battles begun or terminated by agreement (the Mtetwa, Cahto-Yuki, and Mae Enga confrontations), the proportion of warriors killed in action is below 2 percent,”

2. E2 War Before Civilization Oxford University Press (Lawrence H. Keeley, book; hosted at thetedkarchive.com) · 1996

   “The safest conclusion to draw from such a small and mixed sample is that no evidence consistently indicates that primitive battles are proportionately less lethal or less injurious than civilized ones.”

   “the modal pre-state society, that is, nomadic HGs, which represents the broad sweep of human prehistory from roughly 200,000 BC to 10,000 BC, rarely engaged in war and did not suffer high casualties.”

   “However, the majority of killing in non-state warfare occurs during ambushes and small raids on villages.”

E4 supports part (c), stating that most killing in non-state warfare happens in ambushes and small raids. On part (b), the same Keeley source is split: E1 reports under 2 percent of warriors killed in several formal battles, while E2 concludes the small, mixed sample does not show primitive battles were proportionately less lethal than civilized ones. No evidence directly addresses part (a) on whether men regularly accept high lethal risk, and E3 concerns nomadic hunter-gatherers rather than tribal warfare. With one part supported, one divided and one unaddressed, the evidence points to a mixed outcome.
