This is a very inspiring talk by Julia Galef on the psychological phenomena of motivated reasoning – a very common scenario in conversations, in which you feel strong about an idea and look for any supporting detail to assist your argument, even if you feel you may be wrong. She looks at two mindsets: the soldier mindset and the scout mindset. The soldier mindset is aiming at winning the argument and looking for any supporting detail to shoot down the opposing idea. The scout mindset is focused on understanding the argument, looking for the reasoning of both opposing ideas, looking for the underlying information and yearning to see the world as clearly as one possibly can.
