#15. Kevin Dorst has amazing theories on the rationality of human thinking.
Timeline
03:30 - You just believe that because...: people from different environments with different upbringings predictably develop different political beliefs
7:30 There's something problematic about the fact that you could've believe differently than you do now so easily (if I would have been born 100km to the north-east I probably would believe in God right now)
12:00 Why the fact that your beliefs will predictably move in a certain direction is often a sign you're being irrational
16:00 How ambigious evidence explains polarization
26:00 Why confirmation bias is rational
30:00 What really drives confirmation bias
38:00 Is it rational to be more critical of uncongenial evidence?
44:00 Recent studies (e.g. Anglin 2019) show polarization and belief perseverance to be rarer than previously thought
48:00 Standard normative models of rational belief and action are wrong about how rational people would think and act
