| Supervaluation, philosophy: The term goes back to a proposal by B. van Fraassen (“The Journal of Philosophy”, Vol. 63, No. 17, (Sept. 15, 1966), pp. 481-495). If not enough information is available for a decision, the consequences of different possible decisions are compared. Cases which each time produce the truth value t are called "super-true", corresponding for the truth value f as "super-false". One problem is the persistence of truth value gaps. See also truth value clusters, truth value gaps, valuation, evaluation, vagueness, sorites, indeterminacy, dialethism, paradoxes._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Niko Strobach on Supervaluation - Dictionary of Arguments
Strobach I 142 Supervaluation/van Fraassen/Strobach: Proto value: is awarded for a possible world at a time. >Truth values, >Possible worlds. But not true/false, but pure offsetting unit. Junctors: like in propositional logic. >Juctions, >Connectives, >Propositional logic. Atomic statements: then automatically with location and date. Accessibility: varies with the point of time. Alternatives: are worlds that are identical up to t. >Accessibility. Alternatives: Alternatives are worlds that are identical up to t. >Situations, >Identity, >Comparisons, >Comparability, >Change. Evaluation/Supervaluation: ProtoV(~a,‹w,t›) = 1 iff ProtoV(a,‹w,t›) = 0. ProtoV(a v b,‹w,t›) = 1 iff ProtoV(a ,‹w,t›) = 1 ProtoV(~b,‹w,t›) = 1 Accessible world w-™ applies: ProtoV(a,) = 0. Future: here truth value gaps are allowed. >Future, >Truth value gaps. "V(p,) = 1" can be interpreted as "p is true up to w-like reality including t". Actual world: is neither w1 nor w2. >Actual world._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
