 Popper never succeeded in formulating a good formal theory to measure this amount of information although in later writings he suggests that Shannon’s theory of information might be useful (Popper 1934 [1977], 404 [Appendix IX, from 1954]). These issues were later developed in philosophy of science. Theory of conformation studies induction theory and the way in which evidence “supports” a certain theory (Huber 2007  [OIR]).  Although the work of Carnap motivated important developments in both philosophy of science and philosophy of information the connection between the two disciplines seems to have been lost. There is no mention of information theory or any of the more foundational work in philosophy of information in Kuipers (2007a), but the two disciplines certainly have overlapping domains. (See, e.g., the discussion of the so-called Black Ravens Paradox by Kuipers (2007b) and Rathmanner &amp; Hutter (2011).)
