Does power corrupt, or are corrupt people drawn to power? Are entrepreneurs who embezzle and cops who kill the result of poorly designed systems or are they just bad people? Are tyrants made or born? If you were suddenly thrust into a position of power, would you be able to resist the temptation to line your pockets or seek revenge against your enemies? To answer these questions, I spoke to Dr. Brian Klaas, who is Associate Professor in Global Politics at University College London, a columnist for The Washington Post, and who has advised governments, US political campaigns, NATO, the European Union and multi-billion dollar NGOs. In his latest book, Corruptible: Who Gets Power and How it Changes Us, Brian combined decades of research with over 500 interviews with leaders including presidents, philanthropists, cult-leaders, dictators and entrepreneurs. In this interview, I speak to Dr. Brian Klaas about why our societies concentrate power into hierarchies and why our power systems attract certain types of leaders. We also talk about how we can design systems that can prevent corruption and abuses of power together with how we can attract, and empower, a better class of leader.
