Thanksgiving guilt trip: How warlike were Native Americans before Europeans showed up?

The approach of Thanksgiving, that quintessential American holiday, has me brooding over recent scientific portrayals of Native Americans as bellicose brutes. When I was in grade school, my classmates and I wore paper Indian headdresses and Pilgrim hats and reenacted the "first Thanksgiving," in which supposedly friendly Native Americans joined Pilgrims for a fall feast of turkey, venison, squash and corn. This episode seemed to support the view—often (apparently erroneously) attributed to the 18th-century philosopher Jean-Jacques Rousseau—of Native Americans and other pre-state people as peaceful "noble savages".

As I've pointed out previously, prominent scientists now deride depictions of pre-state people as peaceful. "Contra leftist anthropologists who celebrate the noble savage," the Harvard psychologist Steven Pinker wrote in 2007, "quantitative body counts—such as the proportion of prehistoric skeletons with ax marks and embedded arrowheads or the proportion of men in a contemporary foraging tribe who die at the hands of other men—suggest that pre-state societies were far more violent than our own." According to Pinker, the 17th-century philosopher Thomas Hobbes "got it right" when he called pre-state life a "war of all against all."
