On The Mind Report, Paul talks to David about his recent TED talk about the politics of disgust. Paul asks David for a theory of why we connect repugnance and wrongness, and they argue about whether we pass moral judgment on a baby with a dirty diaper. Both Paul and David agree that disgust is not a good guide to morality. They next consider the dismissal of reason as a trend in academic psychology. Paul and David close by explaining how the lessons of social psychology can help with everyday life.
