Today was Refine's third blogpost day. I find it hard to write blogposts. The voice of the inner critic is too loud. The voice of Adam Shimi too is powerful. I'm caught between a rock and a hard place.

so I wrote some shortforms:

Dutch Book Fundamentalism I:the bets we are willing to offer and take don't just constrain our beliefs - they are our beliefs

Two shortforms on Imprecise Probability (related to InfraBayesianism):

Imprecise Probability I: the Bid-Ask Spread measures AdversarialityI enumerate some examples where the bid-ask spread is a rational measure of adversarial action. Bid-ask spread is a fundamental notion of rational belief and action, not just an accidental feature of trading.

Speculations on the correct notion of Information FlowSome speculations on the correct definition of Information Flow. A major obstacle are collections of random variables XORed variables and higher-order dependencies. Shannon information theory does not deal well with these. I speculate on how and whether factored sets, cyclic causality and information cohomology might help.
