In nature, animals roar and bare their teeth to intimidate adversaries — but one side usually backs down, and real fights are rare. The wisdom of evolution is that the risk of violence is just too great.Which might make one wonder: if war is so destructive, why does it happen? The question may sound naïve, but in fact it represents a deep puzzle. If a war will cost trillions and kill tens of thousands, it should be easy for either side to make a peace offer that both they and their opponents prefer to actually fighting it out.The conundrum of how humans can engage in incredibly costly and protracted conflicts has occupied academics across the social sciences for years. In today's episode, we speak with economist Chris Blattman about his new book, Why We Fight: The Roots of War and the Paths to Peace, which summarises what they think they've learned. Links to learn more, summary and full transcript. Chris's first point is that while organised violence may feel like it's all around us, it's actually very rare in humans, just as it is with other animals. Across the world, hundreds of groups dislike one another — but knowing the cost of war, they prefer to simply loathe one another in peace. In order to understand what’s wrong with a sick patient, a doctor needs to know what a healthy person looks like. And to understand war, social scientists need to study all the wars that could have happened but didn't — so they can see what a healthy society looks like and what's missing in the places where war does take hold. Chris argues that social scientists have generated five cogent models of when war can be 'rational' for both sides of a conflict: 1. Unchecked interests — such as national leaders who bear few of the costs of launching a war. 2. Intangible incentives — such as an intrinsic desire for revenge. 3. Uncertainty — such as both sides underestimating each other's resolve to fight. 4. Commitment problems — such as the inability to credibly promise not to use your growing military might to attack others in future. 5. Misperceptions — such as our inability to see the world through other people's eyes. In today's interview, we walk through how each of the five explanations work and what specific wars or actions they might explain. In the process, Chris outlines how many of the most popular explanations for interstate war are wildly overused (e.g. leaders who are unhinged or male) or misguided from the outset (e.g. resource scarcity). The interview also covers: • What Chris and Rob got wrong about the war in Ukraine • What causes might not fit into these five categories • The role of people's choice to escalate or deescalate a conflict • How great power wars or nuclear wars are different, and what can be done to prevent them • How much representative government helps to prevent war • And much more Chapters:Rob’s intro (00:00:00)The interview begins (00:01:43)What people get wrong about violence (00:04:40)Medellín gangs (00:11:48)Overrated causes of violence (00:23:53)Cause of war #1: Unchecked interests (00:36:40)Cause of war #2: Intangible incentives (00:41:40)Cause of war #3: Uncertainty (00:53:04)Cause of war #4: Commitment problems (01:02:24)Cause of war #5: Misperceptions (01:12:18)Weaknesses of the model (01:26:08)Dancing on the edge of a cliff (01:29:06)Confusion around escalation (01:35:26)Applying the model to the war between Russia and Ukraine (01:42:34)Great power wars (02:01:46)Preventing nuclear war (02:18:57)Why undirected approaches won't work (02:22:51)Democratic peace theory (02:31:10)Exchanging hostages (02:37:21)What you can actually do to help (02:41:25)Producer: Keiran HarrisAudio mastering: Ben CordellTranscriptions: Katy Moore
