Presidents, Supreme Court justices, and CEOs are all disproportionally debaters. This is hardly a coincidence. By tracing his own journey from immigrant kid to world champion, Seo shows how the skills of debating--information gathering, truth finding, lucidity, organization, and persuasion--are often the cornerstone of successful careers and happy lives. Drawing insights from its strategies, structure, and history, Seo teaches readers the skills of competitive debate, and in doing so shows how they can improve their communication with friends, family, and colleagues alike. He takes readers on a thrilling intellectual adventure into the eccentric and brilliant subculture of competitive debate, touching on everything from the radical politics of Malcom X to Artificial Intelligence. Seo proves beyond a shadow of a doubt that, far from being a source of conflict, good-faith debate can enrich our daily lives. Indeed, these good arguments are essential to a flourishing democracy, and are more important than ever at time when bad faith is all around, and our democracy seems so imperiled.
