Many Rationalistas believe that Bayes’s rule is among the normative models that are most frequently flouted in everyday reasoning and which, if better appreciated, could add the biggest kick to public rationality.

It would be nice to see people earn brownie points for acknowledging uncertainty in their beliefs, questioning the dogmas of their political sect, and changing their minds when the facts change, rather than for being steadfast warriors for the dogmas of their clique. Conversely, it could be a mortifying faux pas to overinterpret anecdotes, confuse correlation with causation, or commit an informal fallacy like guilt by association or the argument from authority. The “Rationality Community” identifies itself by these norms, but they should be the mores of the whole society rather than the hobby of a club of enthusiasts.

Man, that essay by Ray really gets around.
Overall sounds like he portrays us pleasantly, which is nice.
