Take homicide. Using old court and county records in England, scholars calculate that rates have plummeted by a factor of 10, 50 and, in some cases, 100—for example, from 110 homicides per 100,000 people per year in 14th-century Oxford to fewer than one homicide per 100,000 in mid-20th-century London. Similar patterns have been documented in Italy, Germany, Switzerland, the Netherlands and Scandinavia. The longer-term trend is even more dramatic, Pinker told me in an interview: “Violent deaths of all kinds have declined, from around 500 per 100,000 people per year in prestate societies to around 50 in the Middle Ages, to around six to eight today worldwide, and fewer than one in most of Europe.” What about gun-toting Americans and our inordinate rate of homicides (currently around five per 100,000 per year) compared with other Western democracies? In 2005, Pinker computes, just eight tenths of 1 percent of all Americans died of domestic homicides and in two foreign wars combined.
As for wars, prehistoric peoples were far more murderous than states in percentages of the population killed in combat, Pinker told me: “On average, nonstate societies kill around 15 percent of their people in wars, whereas today’s states kill a few hundredths of a percent.” Pinker calculates that even in the murderous 20th century, about 40 million people died in war out of the approximately six billion people who lived, or 0.7 percent. Even if we include war-related deaths of citizens from disease, famine and genocide, that brings the death toll up to 180 million deaths, or about 3 percent.

“Beginning in the 11th or 12th [century] and maturing in the 17th and 18th, Europeans increasingly inhibited their impulses, anticipated the long-term consequences of their actions, and took other people’s thoughts and feelings into consideration. A culture of honor—the readiness to take revenge—gave way to a culture of dignity—the readiness to control one’s emotions."
