| "I think such high-ranking men are probably not representative of the typical Yanomamo man. Rising to the top of such groups likely requires a good deal of psychopathy. " It is not at all that clear to me. The thing with psychopathy at least. We have about 15 per cent of psychopaths up there (compared to the societal average of 1 per cent). Contrary to the general myth, even most high-ranking Nazis were paper-pushing conformists rather than psychopaths like Oskar Dirlewanger. Would the Amerindian society fare very differently? First, the groups are relatively small. 100 to 150 persons at most, not a whole country like Weimar Germany. Given high mortality and the fact that women didn't become chiefs, your purely numeric chance of becoming a chief was reasonably high if you lived to be 35 or so, just from the fact that you lived and had a lot of valuable experience (in an illiterate society, the elders are a vital knowledge source). Also, this was a fission-fusion society: smaller groups separated under their own chiefs, went their own way, then came back and fused for some time again. Which opened some positions of "junior chiefs" to prove themselves. Too much eagerness to engage in violence will likely get you killed at a younger age. Serious injuries amount to death in the forest, and even many lighter ones. If you really "optimize for max violence", odds are that you will be killed soon. You cannot win every battle, and some of the deaths described by Valero were basically murders from behind. There was certainly luck involved, but also a mix of other attributes, including your ability to fight. But it is not clear to me that psychopaths would have a decisive advantage. It is fundamentally physically dangerous to be a violent psychopath in a society with zero healthcare. |
