“Our Ancestors Had A Capacity For Violence, But This Was Just One Capacity Among Many”

Carl Zimmer has a really good New York Times profile of pugnacious evolutionary psychologist Steven Pinker, who believes that the world has gotten markedly less violent. An excerpt:

“Dr. Pinker finds an explanation for the overall decline of violence in the interplay of history with our evolved minds. Our ancestors had a capacity for violence, but this was just one capacity among many. ‘Human nature is complex,’ he said. ‘Even if we do have inclinations toward violence, we also have inclination to empathy, to cooperation, to self-control.’

Which inclinations come to the fore depends on our social surroundings. In early society, the lack of a state spurred violence. A thirst for justice could be satisfied only with revenge. Psychological studies show that people overestimate their own grievances and underestimate those of others; this cognitive quirk fueled spiraling cycles of bloodshed.

But as the rise of civilization gradually changed the ground rules of society, violence began to ebb. The earliest states were brutal and despotic, but they did manage to take away opportunities for runaway vendettas.

More recently, the invention of movable type radically changed our social environment. When people used their powers of language to generate new ideas, those ideas could spread. ‘If you give people literacy, bad ideas can be attacked and experiments tried, and lessons will accumulate,’ Dr. Pinker said. ‘That pulls you away from what human nature would consign you on its own.'”
