and seeing people talk about how they’ve never tried rice before having it at the restaurant

And this is the fundamental, absolute, no-further-down essential appeal of rationalism. Fans have never encountered ideas before, or not in any way that they’ve been able to digest them (“what the author really meant: the curtains are fucking blue”). And it bubbles up throughout, in every environ of the culture. If you are ever as stupid and masochistic as I am and find yourself on TheMotte.org, it’s the key to everything they say: they literally have never encountered facts from beyond their own rabid whirlpool of hatred, and everything that they learned in the whirlpool was laced with contrarian ressentiment towards an enemy they literally haven’t seen.

Reading the article is like seeing a guy at a party pick up a guitar, announce he’s going to play wonderwall, but for whatever reason he starts holding the guitar like a trumpet, blowing on the headstock and everything. There’s no indication that this is a joke. A crowd forms and they love it, tunelessly and arrhythmically chanting “wonder wall! Wonder wall!” Over and over. It’s not even part of the song. You see him later making out in a puddle, people still chanting “wonder wall!” at the puddle. Your only recourse is to set the couch on fire and leave.

If you want more of this, I wrote a full critique of his mangled intro to quantum physics, where he forgets the whole "conservation of energy" thing.

Personally, I've always found Cromwell's rule a deeply boring proposal for screwing with the axioms. Try doing the Dutch-book argument with surreal numbers, then I'll pay attention. :-P

(I would expect that many subjectivist Bayesians would take Cromwell's rule as an addition to the basic rules that are themselves justified by Dutch book or some such means. Not assigning sharp-edged probabilities out of general prudence is a thing an individual gambler can choose to do, if that's the way their tendencies lie, while not being part of the mathematical definition of the subject itself. But, well, 46,656 varieties and all that. Moreover, it is hard to do physics having chopped off the endpoints of the interval without chopping other structures as well. For example, if you don't even allow 0 and 1 to be available as idealizations, you might end up peeling the skin off quantum state space. Some could cope with this, but not Yud, since he demands that all of reality be a single pure quantum state. Insofar as any sense can be made out of Yud's rambles, he is wanting something stronger than Cromwell's rule, anyway, since he wants to forbid probability 1 even for logical implications, which Lindley allowed.)
