Social Choice Theory
Many revision proposals involve orderings over models representing the relative plausibility of the possible alternatives. The problem of merging amounts to combine a set of orderings into a single one expressing the combined plausibility of the alternatives. This is similar with what is done in social choice theory, which is the study of how the preferences of a group of agents can be combined in a rational way. Belief revision and social choice theory are similar in that they combine a set of orderings into one. They differ on how these orderings are interpreted: preferences in social choice theory; plausibility in belief revision. Another difference is that the alternatives are explicitly enumerated in social choice theory, while they are the propositional models over a given alphabet in belief revision.

Famous quotes containing the words social, choice and/or theory:
“The social kiss is an exchange of insincerity between two combatants on the field of social advancement. It places hygiene before affection and condescension before all else.”
—Sunday Correspondent (London, Aug. 12, 1990)
“Stupid or smart, there wasnt much choice about what was going to happen to me ... Growing up was like falling into a hole.... I might not quit school, not while Mama had any say in the matter, but what difference would that make? What was I going to do in five years? Work in the textile mill? Join Mama at the diner? It all looked bleak to me. No wonder people got crazy as they grew up.”
—Dorothy Allison (b. 1953)
“... liberal intellectuals ... tend to have a classical theory of politics, in which the state has a monopoly of power; hoping that those in positions of authority may prove to be enlightened men, wielding power justly, they are natural, if cautious, allies of the establishment.”
—Susan Sontag (b. 1933)
