 This resulted in the rise of a new probabilistic paradigm  (Oaksford and Chater 2007,  Pfeifer and Douven 2014) where  probability theory provides a calculus for rational belief update. Although the program is sometimes phrased in decidedly anti-logicist  terms,[7]  logic is here usually understood as monotonic and deductive. The relation to NML is less clear and it has been argued that there are close connections especially to probabilistic accounts of NML  (Over 2009,  Pfeifer and Kleiter 2009).  Politzer and Bonnefon 2009  warn against the premature acceptance of the probabilistic paradigm in view of the rich variety of alternatives such as possibility measures, plausibility measures, etc.).
