You've probably watched a talk show or political magazine program featuring politicians from different parties or political movements. And you've likely noticed at least two things: First, it's surprisingly easy to predict which opinions and arguments the politicians will present on a given topic. Second, these media discussions, at best, contribute to a collection of available opinions, but never to any kind of rapprochement or consensus. Bestselling author Bernhard Hommel explains why this is the case in his new book and shows how we can better understand each other.
