In theory, people should want to know accurate facts about the state of the world. In practice, it's not so simple. Because of the way we evolved, and how our brains work, there are often things that we prioritize above the truth (such as fitting in with some tribal identity). On this week's Odd Lots podcast, we speak with NYU professor Jay Van Bavel, about a new paper he co-authored titled "The Partisan Brain: An Identity-Based Model of Political Belief." It explains how political ideology leads people to have distorted views of the world, and though this paper is specifically about politics, it contains important lessons for people in the market, as they seek to overcome the biases that make them bad traders and investors.
