 Yet, the concept of qualitative probability is sometimes considered flawed: a complete set of probabilistic-logical principles guaranteeing that every complete description in the logical language corresponds to a unique probability measure turns out to require a complex calculus, involving an opaque infinite rule (Kraft, Pratt, &amp; Seidenberg 1959; Scott 1964). A new angle has been proposed in Harrison-Trainor, Holliday, and Icard (2016) and Ding, Holliday, and Icard (2021)  through axiomatizing a low-complexity qualitative probabilistic logic that emerges from relaxing the above unique correspondence requirement to merely requiring compatibility with all probability measures of a certain family.
