What causes war? Many scholars have spent their careers attempting to study the psychology of leaders to understand what incentivizes them to undertake the human and financial costs of conflict, but economist and political scientist Chris Blattman takes a different approach to understanding interstate violence. He returns for his second appearance on Conversations with Tyler to discuss his research into the political and institutional causes of conflict, the topic of his new book ​​Why We Fight: The Roots of War and The Path to Peace. Chris and Tyler also cover why he doesn’t think demographics are a good predictor of a country’s willingness to go to war, the informal norms that restrain nations, the dangers of responding to cyberattacks, the breakdown of elite bargains in Ethiopia, the relationship between high state capacity and war, the greatest threats to peace in Ireland, why political speech isn’t usually a reliable indicator of future action, Vladimir Putin’s centralized motives for invading Ukraine, why he’s long on Colombia democratically – but not economically, why more money won’t necessarily help the Mexican government curb cartel violence, the single-mindedness necessary for bouldering, how Harold Innis’s insights about commodities led Chris to start studying war, how the University of Chicago has maintained a culture of free inquiry, and more.
