Think you’re absolutely right on the hot political, social or religious debate of the day? Before you get into it with your brother-in-law over Thanksgiving dinner, make sure you read this book. Jonathan Haidt does a masterful job of showing that the other side isn’t as crazy as we think, and in fact, we’re all a bit more crazy than we’d like to admit. He draws on decades of research to show that what we consider to be moral judgments are not formed by sound reasoning, but by intuition. Understanding why and how that happens is critical to understanding each other. And a necessary part of having an opinion.
