Episode 40 of the NonProphets podcast, in which Atief, Robert, and Scott discuss Bitcoin (4:50), summer forecasts (14:10), hurricanes (21:30), team forecasting (32:15), problems of homogeneity in forecasting (37:00), WEIRD bias (42:50), whether egalitarian groups combat groupthink (45:20), and when political opinions become motivated reasoning (50:10). They close with a serious discussion of which trick is best: consulting a Magic 8 Ball or betting against the most unlucky person you can find.
