While some researchers have claimed that war between nations is in decline, a new analysis suggests we shouldn’t be too quick to celebrate a more peaceful world.
The study finds that there is no clear trend indicating that nations are less eager to wage war, said Bear Braumoeller, author of the study and associate professor of political science at The Ohio State University.
Conflict does appear to be less common than it had been in the past, he said. But that’s due more to an inability to fight than to an unwillingness to do so.
“As empires fragment, the world has split up into countries that are smaller, weaker and farther apart, so they are less able to fight each other,” Braumoeller said.
“Once you control for their ability to fight each other, the proclivity to go to war hasn’t really changed over the last two centuries.”
Braumoeller presented his research Aug. 29 in Chicago at the annual meeting of the American Political Science Association.
Several researchers have claimed in recent years that war is in decline, most notably Steven Pinker in his 2011 book The Better Angels of Our Nature: Why Violence Has Declined.
As evidence, Pinker points to a decline in war deaths per capita. But Braumoeller said he believes that is a flawed measure.
“That accurately reflects the average citizen’s risk from death in war, but countries’ calculations in war are more complicated than that,” he said.
Moreover, since population grows exponentially, it would be hard for war deaths to keep up with the booming number of people in the world.
Because we cannot predict whether wars will be quick and easy or long and drawn-out (“Remember ‘Mission Accomplished?'” Braumoeller says) a better measure of how warlike we as humans are is to start with how often countries use force—such as missile strikes or armed border skirmishes—against other countries, he said.
