" In the classic case of the Mountain Arapesh, Margaret Mead maintained they were and had been peaceful, yet there is solid evidence that no more than a generation earlier they had engaged in substantial warfare, thus demonstrating the problem that arises involving warfare with all such studies.25 Thus research by university-trained anthropologists of the twentieth century is much less useful for understanding forager warfare than the early accounts of explorers, missionaries and patrol officers. Such early historic and ethnographic data on the Alaskan Iñupiaq and Aboriginal Australians can be extremely enlightening.26 These early accounts have the potential for bias and lack of completeness and must be used with caution, but such is the case with all data. It appears that the failure to comprehend the problems with recent, twentieth-century ethnographic studies renders the opinions of people like Douglas Fry and Brian Ferguson about peaceful societies virtually worthless.”
