 Roorda (1995) calls this the received view of how full and partial belief ought to interact. Gärdenfors (1986) is a representative of this view, as are van Fraasen (1995) and Arló-Costa (1999), although the latter two accept a slightly non-standard probabilistic modeling for partial belief. For fans of deductive cogency, the following observations ought to count in favor of the received view.
