The Slow Death of Violence

A fascinating, counterintuitive article by Steven Pinker on the slow decline of of violence over the ages:

Our seemingly troubled times are routinely contrasted with idyllic images of hunter-gatherer societies, which allegedly lived in a state of harmony with nature and each other. The doctrine of the noble savage—the idea that humans are peaceable by nature and corrupted by modern institutions—pops up frequently in the writing of public intellectuals like, for example, Spanish philosopher José Ortega y Gasset, who argued that "war is not an instinct but an invention."

But now that social scientists have started to count bodies in different historical periods, they have discovered that the romantic theory gets it backward: Far from causing us to become more violent, something in modernity and its cultural institutions has made us nobler. In fact, our ancestors were far more violent than we are today. Indeed, violence has been in decline over long stretches of history, and today we are probably living in the most peaceful moment of our species' time on earth…

When the archeologist Lawrence Keeley examined casualty rates among contemporary hunter-gatherers—which is the best picture we have of how people might have lived 10,000 years ago—he discovered that the likelihood that a man would die at the hands of another man ranged from a high of 60 percent in one tribe to 15 percent at the most peaceable end. In contrast, the chance that a European or American man would be killed by another man was less than one percent during the 20th century, a period of time that includes both world wars. If the death rate of tribal warfare had prevailed in the 20th century, there would have been two billion deaths rather than 100 million, horrible as that is…

When the criminologist Manuel Eisner scoured the records of every village, city, county, and nation he could find, he discovered that homicide rates in Europe had declined from 100 killings per 100,000 people per year in the Middle Ages to less than one killing per 100,000 people in modern Europe.

And since 1945 in Europe and the Americas, we've seen steep declines in the number of deaths from interstate wars, ethnic riots, and military coups, even in South America. Worldwide, the number of battle deaths has fallen from 65,000 per conflict per year to less than 2,000 deaths in this decade. Since the end of the Cold War in the early 1990s, we have seen fewer civil wars, a 90 percent reduction in the number of deaths by genocide, and even a reversal in the 1960s-era uptick in violent crime.

There's a terrific book by political scientist James L. Payne (who's also mentioned in Pinker's article) called A History of Force that documents all of this in much more detail.
