Social choice theory is a subfield of political theory concerned with the logic of collective decision-making, whether voting or multicriterion decision-making.
As such it is a subset of rational choice theory, which includes the logic of individual as well as collective choice.

  SLINGING ARROWS AT DEMOCRACY: SOCIAL CHOICE THEORY, VALUE PLURALISM, AND DEMOCRATIC POLITICS   (Site not responding. Last check: 2007-10-16)
Social choice theory necessarily describes options in outcome-oriented terms: the choice is, to elect or defeat this candidate, [*2145] to pass or defeat this piece of legislation, to find for or against a plaintiff.
Social choice theorists, however, might respond by narrowing the scope of the claims made on behalf of the theory and arguing that it should be viewed to challenge merely the capacity of voting procedures to be both fair and rational.
Social choice theory is a response to the problem of defining the institutions or processes by which laws and policies must be generated before their coercive enforcement and pursuit is justified.

 Making Democracy Meaningful
Social choice, derived from economic theories of rationality, has become a dominant empirical and theoretical method, informing the assumptions and analysis of researchers in all subfields.
Accepting the premises of social choice theory, we show that the major theoretical understandings of democracy not only escape the social choice critique but are, in fact, both consistent with and even implied by the social choice approach.
After first rehearsing the social choice critique and discussing various general ways in which the integrity of the majority principle might survive the attack, we turn to a systematic analysis of some core understandings of democracy.

 Social Choice and Beyond - Papers
Social Choice is an important field because, if in fact Social Choice is impossible, there is no solid theoretical ground for a satisfactory version of political democracy and also any possible version of economic democracy would likewise be invalidated.
For the case of two alternatives, Arrow proves that social choice is possible only by virtue of violating the Principle of Neutrality (while complying with Citizens' Sovereignty) and treating x and y differently when half the voters prefer y to x and half prefer x to y.
A proof is presented that the algorithm provides a social choice solution for all values of m when individual and social choices are expressed in terms of the R (preference or indifference) operator, and for all values of n, the number of voters.

So, yeah, it sounds like the social choice guys are trying to reason without the complications of morality, and then some of them sneak it in at the end (wittingly or unwittingly).
Social choice theorists want to have a method which would be accepted as fair as a voting system even if we were under a "Rawlsian veil of ignorance" as to what the choices would be.

 Choice Summary
Choice consists of that mental process of thinking involved with the process of judging the merits of multiple options and selecting one for action.
On the contrary, unlimited choice may lead to confusion, regret of the alternatives not taken, and indifference in an unstructured existence; and the illusion that choosing an object or a course leads necessarily to control of that object or course can cause psychological problems.
Children and citizens are no longer able to practice free choice in what they believe because their beliefs have been tainted by social institutions-they no longer know in what to believe.

 Social Choice Theory
Social choice theory is the brance of decision theory concerning agents who all agree to be bound by the outcome of a social choice procedure, such as a vote.
It states that the socially chosen outcome should not change when unchosen options are eliminated from the preference profile.
These examples are instances of a more general problem, which is that it is impossible to find a social choice function which satisfies all the criteria we would like it to.

 Political Science 44
The general approach of rational choice theories is to begin with deductive principles of human behavior, construct models of what results these behaviors ought to have, given particular rules or laws, and come up with hypothetical results.
To critics of these models, rational choice theories represent a simplistic, and often unfalsifiable, explanation of human behavior that offers no role to chance, to personality, to human emotions, or other aspects of an event that cannot be neatly categorized within a mathematical model of what "should" happen.
We will attempt to contextualize these theories within the broader goals of the social sciences and to explore the controversies that still surround the question of whether these theories are a legitimate means of analyzing social and political phenomena.

 Amartya Sen: Rationality and Freedom
It is centrally important for social choice theory to relate formal analysis to informal and transparent examination.
Likewise, while Sen's ways of comparing utility or making social choice decisions are completely OK as far as I am concerned, they seem unlikely to be useful to an economist hoping to weave an rigorous, elaborate theoretical structure.
My opinion is that Sen has finally returned us to reasonable positions on rationality, distribution, and social choice which could easily have been attained fifty or sixty years ago (and probably was), and that the long detour through formalization has been harmful.

 Survivor, Social Choice, and the Impedi
Redlands, CA Social choice theory occupies a privileged explanatory position within much of the social sciences, particularly economics, psychology, sociology, and political science.
  Social choice theory argues that the outcomes of collective action may be explained in terms of the calculation of costs and benefits in pursuit of individual preferences.
  Rational choice encompasses a wide range of methods, all of which attempt to explain and predict human behavior by assuming the primacy of instrumental rationality, which merely means that individuals will always choose to pursue their self-interest by the most efficient strategy available to them.

 社会决策 Social Choice Theory-CPO心理热线
  The approval social choice function requires of each individual that she partition the set X into two subsets, one of which contains the alternatives she approves, while the other of which contains the alternatives she disapproves.
The problem is to find a general mechanism, called a social choice function, which transforms the set of preference orders, one for each individual, into a global societal preference order.
This social choice function should have several desirable properties: unrestricted domain or universality: the social choice function should create a complete societal preference order from every possible set of individual preference orders.

 Liberalism, Democracy, and Social Choice
David Miller, in "Deliberative Democracy and Social Choice," presents social choice theory within a deliberative model of democracy, juxtaposed against the liberal theory of the citizen which employs rational choice theory.
Both pieces are of significant weight within the scope of this course, the former primarily for the debate surrounding the supposed kinship between capitalism and democracy, and the latter mostly for exploration of the possibilities for the expansion of democracy.
Liberals claim that state ownership of all productive property would give it the power "to deny resources and even a livelihood to those" who were against its policies; plus it would have to do so, in order to prevent the emergence of parties which would work for the restitution of private property.
