Th is paper investigates the epistemic powers of democratic institutions through an assessment of three epistemic models of democracy : the Condorcet Jury Th eorem, the Diversity Trumps Ability Th eorem, and Dewey's experimentalist model. Dewey's model is superior to the others in its ability to model the epistemic functions of three constitutive features of democracy : the epistemic diversity of participants, the interaction of voting with discussion, and feedback mechanisms such as periodic elections and protests. It views democracy as (...) an institution for pooling widely distributed information about problems and policies of public interest by engaging the participation of epistemically diverse knowers. Democratic norms of free discourse, dissent, feedback, and accountability function to ensure collective, experimentallybased learning from the diverse experiences of diff erent knowers. I illustrate these points with a case study of community forestry groups in South Asia, whose epistemic powers have been hobbled by their suppression of women's participation. (shrink)

A good part of the early literature on deliberative democracy has focused on moral arguments for or against deliberative democracy. These arguments have typically been divided into instrumental and non‐instrumental arguments. More recently, there has been an epistemic turn in the literature on deliberative democracy. The main question under debate is no longer whether we have moral reasons to make our political decisions in deliberative democratic fashion, but whether or not we have epistemic reasons to do so. Epistemic arguments for (...) and against deliberative democracy can also be divided instrumental and non‐instrumental arguments. My chapter on the epistemology of deliberative democracy will give an overview over this new debate. (shrink)

Jury theorems are mathematical theorems about the ability of collectives to make correct decisions. Several jury theorems carry the optimistic message that, in suitable circumstances, ‘crowds are wise’: many individuals together (using, for instance, majority voting) tend to make good decisions, outperforming fewer or just one individual. Jury theorems form the technical core of epistemic arguments for democracy, and provide probabilistic tools for reasoning about the epistemic quality of collective decisions. The popularity of jury theorems spans across various disciplines such (...) as economics, political science, philosophy, and computer science. This entry reviews and critically assesses a variety of jury theorems. It first discusses Condorcet's initial jury theorem, and then progressively introduces jury theorems with more appropriate premises and conclusions. It explains the philosophical foundations, and relates jury theorems to diversity, deliberation, shared evidence, shared perspectives, and other phenomena. It finally connects jury theorems to their historical background and to democratic theory, social epistemology, and social choice theory. (shrink)

Inspired by impossibility theorems of social choice theory, many democratic theorists have argued that aggregative forms of democracy cannot lend full democratic justification for the collective decisions reached. Hence, democratic theorists have turned their attention to deliberative democracy, according to which “outcomes are democratically legitimate if and only if they could be the object of a free and reasoned agreement among equals” (Cohen 1997a, 73). However, relatively little work has been done to offer a formal theory of democratic deliberation. This (...) article helps fill that gap by offering a formal theory of three different modes of democratic deliberation: myopic discussion, constructive discussion, and debate. We show that myopic discussion suffers from indeterminacy of long run outcomes, while constructive discussion and debate are conclusive. Finally, unlike the other two modes of deliberation, debate is path independent and converges to a unique compromise position, irrespective of the initial status quo. (shrink)

We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) (...) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (nonasymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

In Between Facts and Norms, Jürgen Habermas works out the legal and political implications of his Theory of Communicative Action (1981), bringing to fruition the project announced with his publication of The Structural Transformation of the Public Sphere in 1962. This new work is a major contribution to recent debates on the rule of law and the possibilities of democracy in postindustrial societies, but it is much more. The introduction by William Rehg succinctly captures the special nature of the work, (...) noting that it offers a sweeping, sociologically informed conceptualization of law and basic rights, a normative account of the rule of law and the constitutional state, an attempt to bridge normative and empirical approaches to democracy, and an account of the social context required for democracy. Finally, the work frames and caps these arguments with a bold proposal for a new paradigm of law that goes beyond the dichotomies that have afflicted modern political theory from its inception and that still underlie current controversies between so-called liberals and civic republicans. The book includes a postscript written in 1994, which restates the argument in light of its initial reception, and two appendixes, which cover key developments that preceded the book. Habermas himself was actively involved in the translation, adapting the text as necessary to make it more accessible to English-speaking readers. (shrink)

This latest work from one of the world's leading political philosophers will appeal to audiences from a variety of fields, including philosophy, political science, women's studies, ethnic studies, sociology, and communications studies.

The maze and the masses -- Democracy as the rule of the dumb many? -- A selective genealogy of the epistemic argument for democracy -- First mechanism of democratic reason: inclusive deliberation -- Epistemic failures of deliberation -- Second mechanism of democratic reason: majority rule.

This paper argues in favor of the epistemic properties of inclusiveness in the context of democratic deliberative assemblies and derives the implications of this argument in terms of the epistemically superior mode of selection of representatives. The paper makes the general case that, all other things being equal and under some reasonable assumptions, more is smarter. When applied to deliberative assemblies of representatives, where there is an upper limit to the number of people that can be included in the group, (...) the argument translates into a defense of a specific selection mode of participants: random selection.

The two most influential traditions of contemporary theorizing about democracy, social choice theory and deliberative democracy, are generally thought to be at loggerheads, in that the former demonstrates the impossibility, instability or meaninglessness of the rational collective outcomes sought by the latter. We argue that the two traditions can be reconciled. After expounding the central Arrow and Gibbard-Satterthwaite impossibility results, we reassess their implications, identifying the conditions under which meaningful democratic decision making is possible. We argue that deliberation can promote (...) these conditions, and hence that social choice theory suggests not that democratic decision making is impossible, but rather that democracy must have a deliberative aspect.

This book examines the Condorcet Jury Theorem and how its assumptions can be applicable to the real world. It will use the theorem to assess various familiar political practices and alternative institutional arrangements, revealing how best to take advantage of the truth-tracking potential of majoritarian democracy.

This essay asks why Aristotle, certainly no friend to unlimited democracy, seems so much more comfortable with unconstrained rhetoric in political deliberation than current defenders of deliberative democracy. It answers this question by reconstructing and defending a distinctly Aristotelian understanding of political deliberation, one that can be pieced together out of a series of separate arguments made in the Rhetoric, the Politics, and the Nicomachean Ethics.

Why democracy? Most often this question is met with an appeal to some decidedly moral value, such as equality, liberty, dignity or even peace. But in contemporary democratic societies, there is deep disagreement and conflict about the precise nature and relative worth of these values. And when democracy votes, some of those who lose will see the prevailing outcome as not merely disappointing, but morally intolerable. How should citizens react when confronted with a democratic result that they regard as intolerable? (...) Should they revolt, or instead pursue democratic means of social change? In this book, Robert Talisse argues that each of us has reasons to uphold democracy - even when it makes serious moral errors - and that these reasons are rooted in our most fundamental epistemic commitments. His original and compelling study will be of interest to a wide range of readers in political philosophy and political theory. (shrink)

This essay criticizes the current approach to epistemic democracy. Epistemic democrats are preoccupied with the question of how a society can best exploit a given stock of knowledge. This article argues that the problem-solving capability of a society depends on two factors rather than one. The quality of decision-making depends both on how a democracy is able to make use of its stock of knowledge and on the size of the knowledge stock. Society’s problem-solving capability over time is therefore a (...) function of its ability to develop its knowledge exploitation mechanisms and the growth rate of its knowledge stock. Based on this enhanced model of social problem-solving, this essay compares two different political ideal types: experimental democracy, as commonly defended by epistemic democrats; and polycentric democracy, a model defended most commonly by political economists.

Abstract:We present a model of collective decision making in which aggregation and deliberation are treated simultaneously. Individuals debate in a public forum and potentially revise their judgements in light of deliberation. Once this process is exhausted, a rule is applied to aggregate post-deliberation judgements in order to make a social choice. Restricting attention to three alternatives, we identify conditions under which a democracy is ‘truth-revealing’. This condition says that the deliberation path and the aggregation rule always lead to the correct (...) social choice being made, irrespective of both the original profile of judgements and the size of the electorate.
