As an aside, a reason I find the rationality community interesting is that they nominally respect the epistemic values I strive for, but they generally embody the opposite and are wildly overconfident (ofc. there are exceptions)
I remember reading the pre-LW stuff and thinking "oh, cool. Other people who are trying to mitigate the impact of cognitive biases on their own thinking" and then "weird. These people are super overconfident about things they know nothing about, especially the leaders"
