Chris Blattman on Why We Fight: The Roots of War and Paths to Peace

Chris Blattman, a professor at the University of Chicago, delves into the fundamental causes of violence and war, drawing from economics, political science, and psychology. His new book, "Why We Fight: The Roots of War and the Paths to Peace," posits that war, defined as a prolonged violent struggle between groups, is fundamentally puzzling because it is almost always costly for all parties involved and rarely the best option. He distinguishes this from short, communicative acts of violence or individual conflicts, emphasizing that true war represents a breakdown of reason and negotiation, where a more efficient, less brutal outcome should theoretically be achievable.

Blattman challenges the common perception that war is an inherent, deeply human impulse, arguing instead that humans are primarily cooperative. He uses a medical analogy, suggesting that war is a 'disease' in a generally 'healthy' system, and by understanding its roots, we can become 'better doctors of politics.' He outlines five primary reasons why conflicts escalate into war, categorizing three as strategic (leaders not bearing costs, uncertainty/information asymmetry, and commitment problems due to anticipated power shifts) and two as human (ideologies/principles overriding costs, and irrationalities/misperceptions leading to wrong calculations).

The discussion explores the complexities of defining war, noting the difficulties in quantitative analysis due to subjective start/end points and the propaganda of self-defense. It touches upon the concept of 'just war' and the strategic considerations that can compel a nation to invade, even when an alternative, peaceful resolution seems possible. Blattman highlights that most potential conflicts (e.g., 999 out of 1000 disputes between nations or ethnic groups) are actually avoided, demonstrating the prevalence of peaceful, albeit sometimes resentful, coexistence.

Ultimately, the podcast emphasizes that while game theory can model many strategic aspects of conflict, the human element of irrationality and misperception remains a significant, complex factor. By understanding these underlying mechanisms—both strategic and psychological—Blattman aims to provide a framework for comprehending why wars occur and, by extension, how they might be prevented, moving beyond simplistic notions of inherent human aggression to a more nuanced view of conflict as a breakdown of otherwise sensible cooperation.

"Let me be clear what I mean when I say war I don't just mean countries duking it out I mean any kind of prolonged violent struggle between groups that includes villages clans gangs ethnic groups religious sects political factions and nations"

"The thing that all of it has in common is that it doesn't generally make sense. It's not your best option most of the time."

"War is the thing that we shouldn't be doing or where's the violence that doesn't make sense."

"Everybody loses something from war and there was usually not always but this the point is there was usually a way to get what you wanted or be better off without having to fight over it."

"Fighting is just politics by other means and it's just inefficient costly brutal devastating means."

"Most people don't know about the US invasion of Haiti in 1994... it didn't actually happen because before the troops could land the person who'd taken power in a coup basically said fine."

"Whatever some number like 999 out of a thousand don't don't fight... because they just find some other way they don't like each other but they they just loathe in peace because that's the sensible thing to do."

"I actually don't think war beats in our heart it does a little bit but we're actually very cooperative we're as a species we're deeply deeply cooperative we're really really good."

"Let's be better doctors of politics in the world by recognizing that like normal state is health and then we're going to identify like what are the diseases that are causing this warfare."

"There's a reason for every war and a war for every reason and that's true and it's kind of overwhelming."

"Four of those five [roots of war] are really on some level easy to think strategically and model in a simple way."

"The downside of of game theory is not that it helps us make sense of the world it projects a simple model of the world that brings us comfort in thinking we understand."
