 Combinative preferences can be derived from exclusionary preferences, which are then taken to be more basic. In most variants of this approach, the underlying alternatives (to which the exclusionary preferences refer) are possible worlds, represented by maximal consistent subsets of the language (Rescher 1967, von Wright 1972).  However, it has been argued that a more realistic approach should be based on smaller alternatives that cover all the aspects under consideration – but not all the aspects that might have been considered. This approach may be seen as an application of Simon’s “bounded rationality view” (Simon 1957, 196–200).
