ABSTRACT In its attempt to prove that voters, politicians, and bureaucrats are motivated by the public interest, Self-Interest and Public Interest in Western Politics overlooks a great deal of public-choice research, to which much has been added during the two decades since it was published. The importance of self-interest at both the micro and macro levels of politics becomes clear once one looks not simply at the ?inputs? of a democracy but at its ?outputs? as well. The prevalence of interest (...) groups, the dysfunction of the United States tax code, the lobbying by unions for their members? self-interest, the earmarks in the Patriot Act, the numerous cases of corruption in Western democracies, and the dissatisfaction of citizens with their governments? failings all point to the importance of self-interest in politics.

This paper generalises the classical Condorcet jury theorem from majority voting over two options to plurality voting over multiple options. The paper further discusses the debate between epistemic and procedural democracy and situates its formal results in that debate. The paper finally compares a number of different social choice procedures for many-option choices in terms of their epistemic merits. An appendix explores the implications of some of the present mathematical results for the question of how probable majority cycles (as in (...) Condorcet's paradox) are in large electorates. (shrink)
