Belief Revision - Social Choice Theory

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 conservative assumes sickness as a necessity, and his social frame is a hospital, his total legislation is for the present distress, a universe in slippers and flannels, with bib and papspoon, swallowing pills and herb-tea.
    Ralph Waldo Emerson (1803–1882)

    The majority of persons choose their wives with as little prudence as they eat. They see a trull with nothing else to recommend her but a pair of thighs and choice hunkers, and so smart to void their seed that they marry her at once. They imagine they can live in marvelous contentment with handsome feet and ambrosial buttocks. Most men are accredited fools shortly after they leave the womb.
    Edward Dahlberg (1900–1977)

    The theory of rights enables us to rise and overthrow obstacles, but not to found a strong and lasting accord between all the elements which compose the nation.
    Giuseppe Mazzini (1805–1872)
