People often assume the worst of people we disagree with, especially those who hold opposing political views, and especially in America today. We know that when *other* people do this, they are usually being irrational — they're experiencing what behavioral economist Dan Stone calls "undue hate." But we very rarely see this in ourselves. Why do we tend to make this mistake — to dislike people we disagree with more than we should — and how can we become more self-aware when we make this mistake? Our best bet may be to better understand the range of cognitive biases that contribute to undue hate. In this talk, Stone explains four of these biases and how all four boil down to one underlying psychological factor: WYSIATI (What You See Is All There Is).#UndueHate #Politics #DisagreeBetter #Right #Left #Bias Dan Stone is Associate Professor and chair of the Economics department at Bowdoin College, author of Undue Hate (MIT Press, 2023), and advisor to the anti-polarization organizations Starts With Us, More Like Us, and Braver Angels. His team's submission to Stanford University's Strengthening Democracy Challenge yielded the largest reduction in emotional polarization among the 25 tested. Stone has taught behavioral economics at Bowdoin and Oregon State University since 2011, and his research is on polarization, biases in beliefs, media, sports, and socially responsible capitalism. He has also served with Americorps, worked for the consulting company Novantas, and coaches youth baseball, basketball, and soccer. Originally from Charlottesville, VA, Stone lives in Brunswick, Maine, with his spouse and two children.
