3.2 Social Choice Theory Social Choice Theory is the study of collective decision making processes, most commonly used to analyze voting systems. It has its roots in the 18th century with the mathematical contributions to social sciences of Nicolas de Condorcet and Jean-Charles de Borda. Through the work of a few notable scholars (Sen, 1984; Arrow, 1951; Rawls, 1999), the theory became known as a tool to understand individual utility and one’s ability to function within the same capability set as any other member of society. The theory is most often attributed to Kenneth Arrow and his book, ‘Social Choice and Individual Values’ (1951). In it, he discusses different aggregation methods of individual preferences meant to lead to collective …show more content…

Sen understood Arrow’s Theorem as proof that ordinal analysis of individual preferences was not well suited to the creation of social choices. Instead, Sen argues, what is needed is simply a stronger informational base (Sen, 1986). John Rawls’ ‘Difference Principle’ was a first step in satisfying this requirement and a direct response to Arrow’s Impossibility Theorem. The principle was most concerned with the utility level of those considered worst off in a society by focusing on interpersonal comparisons and non-utility information in analyses of wellbeing (Rawls, 1999). In other words, it is not satisfactory to simply compare utility in its traditional sense; one must compare social states, personal circumstance and all other criteria deemed valuable to a person’s life. Rawls, like Kant, believed humans have the capacity to reason from a universal point of view. Rawls’ called this the ‘original position’ (Rawls, 1999) and argued humans reach their individual moral and political understandings through an impartial analysis of the world around them. In this Rawlsian state of nature, humans are free of the biases that come with knowledge of individual circumstance, which thus leaves them free to consider principles that, Rawls argues, are inherently
