I don’t see the connection to the Jeffrey-Bolker rotation? There, to get the shouldness coordinate, you need to start with the epistemic probability measure, and multiply it by utility; here, utility is interpreted as a probability distribution without reference to a probability distribution used for beliefs.

I think someone should show what P(X|M_2) looks like after a Jeffrey-Bolker rotation, and see if there’s a nice interpretation of what happens.
