This paper contributes to growing debates over the decision-making ability of democracy by considering the epistemic value of deliberative democracy. It focuses on the benefits democratic deliberation can derive from its diversity, and the extent to which these benefits can be realised with respect to the complexities of political problems. The paper first calls attention to the issue of complexity through a critique of Hélène Landemore and the Diversity Trumps Ability Theorem. This approach underestimates complexity due to its reliance on (...) an ‘oracle assumption’ and this is shown to highlight more general difficulties for applying the benefits of diversity to the realities of political problems. The paper then develops a new model of deliberation—based on an relationship between cognitive diversity and diminishing returns to cognitive type—which does not involve an oracle assumption and can therefore support the epistemic value of deliberative democracy even for complex problems. The benefits of diversity are also argued to be better realised though sortition than either democratic elections or epistocracy, pointing to the value of deliberation between randomly selected citizens. Finally, and contrary to past work, the new account suggests that diversity cannot alone establish the superiority of democratic deliberation over all non-democratic alternatives, and that it is insufficient to mount a purely epistemic argument for deliberative democracy. The paper therefore furthers our understanding of the epistemic value of deliberative democracy by clarifying when and to what extent diversity is a benefit to political problem solving. (shrink)

On August 30, 2013, the American Political Science Association sponsored a roundtable on political epistemology as part of its annual meetings. Co-chairing the roundtable were Jeffrey Friedman, Department of Government, University of Texas at Austin; and Hélène Landemore, Department of Political Science, Yale University. The other participants were Scott Althaus, Department of Political Science, University of Illinois at Urbana-Champaign; Mark Bevir, Department of Political Science, University of California at Berkeley; Rogers Smith, Department of Political Science, University of Pennsylvania; and Susan (...) Stokes, Department of Political Science, Yale University. We thank the participants for permission to republish their remarks, which they subsequently edited for clarity. (shrink)

In Democratic Reason, Hne Landemore has built a case for the epistemic virtues of inclusive deliberative democracy based on the cognitive diversity of the group engaged in making collective decisions. She supports her thesis by appealing to the Diversity Trumps Ability Theorem of Lu Hong and Scott Page. This theorem is quite technical and the informal statements of it aimed at democratic theorists are inaccurate, which has resulted in some misguided critiques of the theorem's applicability to democratic politics. This paper (...) provides an exposition of the Diversity Trumps Ability Theorem that does not sacrifice precision for accessibility. It also shows that it is not possible to satisfy the assumptions of this theorem when there are only two options. Thus, the Diversity Trumps Ability Theorem cannot provide support for the epistemic virtues of inclusive democratic deliberation for binary collective decisions. (shrink)

ABSTRACT The “diversity trumps ability” model is often interpreted as a mechanism supporting epistemic democracy. However, as a variety of empirical and mathematical studies have shown, if we attempt to test the realism of the model, it turns out that it points as much toward epistocracy as democracy. This might appear to leave epistocracy with an advantage, since its rationale is not usually thought to rely on the DTA but on the obvious relevance of expertise to making complex decisions. Yet (...) if we apply the same test to epistocracy that we should apply to epistemic democracy—the test of realism—we find that it, too, is unsustainable. This suggests that epistemic democracy and epistocracy alike are indefensible on the basis of the abstract assumptions about diversity and expertise on which the DTA is predicated. (shrink)

Many political philosophers have held that democracy has epistemic benefits. Most commonly, this case is made by arguing that democracies are better able to track the truth than other political arrangements. Truth, however, is not the only epistemic good that is politically valuable. A number of other epistemic goods – goods including evidence, intellectual virtue, epistemic justice, and empathetic understanding – can also have political value, and in ways that go beyond the value of truth. In this paper, I will (...) survey those who have argued that democracy can be valuable because of these other epistemic benefits, considering (1) the ways in which these epistemic goods can be of political value and (2) the challenges that democracies face in producing them.

ABSTRACTReceived wisdom in most democracies is that voting should be seen as a political freedom that citizens have a right to exercise at their discretion. But I propose that we have a duty to vote, albeit a duty to vote well: with knowledge and a sense of impartiality. Fulfillment of this obligation would contribute to the epistemic advantages of democracy, and would thereby instantiate the duty to promote and support just institutions.

ABSTRACTThe idea that the crowd could ever be intelligent is a counterintuitive one. Our modern, Western faith in experts and bureaucracies is rooted in the notion that political competence is the purview of the select few. Here, as in my book Democratic Reason, I defend the opposite view: that the diverse many are often smarter than a group of select elites because of the different cognitive tools, perspectives, heuristics, and knowledge they bring to political problem solving and prediction. In this (...) essay I defend my epistemic argument against proceduralist democrats; the value of model thinking against empiricists; the bracketing of fundamental value diversity against critics who see such diversity as an essential feature of politics; the intelligence of the masses in the face of voter ignorance and systematic biases; and the normative priority of democracy over market mechanisms. I also consider challenges to my use of Hong and Page's formal results, the epistemically proper selection method for representatives, and the role of deliberation in problem solving. I finally chart three avenues for further research. (shrink)

ABSTRACTThis rejoinder represents a final installment in a debate between myself and Paul Gunn over the feasibility and desirability of deliberative democracy. Here I argue that our debate has helped clarify an ambivalence in the literature surrounding the ends and means of deliberative democracy. I specify two ways to understand both ends and means, establish their importance in deliberative theory, and show how they can be combined. I conclude by showing how this systemic view incorporates and overcomes several challenges facing (...) modern democracy, such as the necessity of expert authority, the role of partisanship, and the problem of social complexity.

ABSTRACTThe Hong-Page theorem holds that a group of low-ability, cognitively diverse problem solvers can outperform a more uniform group of high-ability problem solvers. Abigail Thompson’s recent mathematical criticisms of the theorem are incorrect, misleading, or irrelevant to the validity of the theorem. A common thread running through Thompson’s objections is a lack of appreciation for how mathematics is used in social science. One element of her critique that has considerable value for the epistemic democracy literature, however, is her discussion of (...) the importance of randomization for the Hong-Page result. (shrink)

“One who elects to serve mankind by taking the law into his own hands thereby demonstrates his conviction that his own ability to determine policy is superior to democratic decision making. [Defendants’] professed unselfish motivation, rather than a justification, actually identifies a form of arrogance which organized society cannot tolerate.” Those were the words of Justice Harris L. Hartz at the sentencing hearing of three nuns convicted of trespassing and vandalizing government property to demonstrate against U.S. foreign policy. Citizens engaging (...) in civil disobedience are indeed at times accused of being arrogant because they apparently think their own political judgment is superior to that of the democratic majority. This paper examines and evaluates the claim that dissenters are epistemically arrogant. Contrary to the dominant viewpoint in the literature, I argue that epistemic arrogance involves inflating the epistemic worth of one’s view. Indeed, the most plausible charge against civil dissenters consists of two claims: (A) civil dissenters have a higher degree of rational certainty in P than is warranted, and (B) civil dissenters use a method of expression that requires a higher level of rational certainty than is warranted in the propositions that their political view is right and the injustice they fight is substantial. I argue that civil disobedience does not necessarily involve epistemic arrogance. Whether an act of civil disobedience evinces epistemic arrogance has to be determined on a case-by-case basis depending on the extent to which each dissenter lives up to (A) and (B). (shrink)

ABSTRACTNormative political epistemologists, such as epistemic democrats, study whether political decision makers can, in principle, be expected to know what they need to know if they are to make wise public policy. Empirical political epistemologists study the content and sources of real-world political actors' knowledge and interpretations of knowledge. In recent years, empirical political epistemologists have taken up the study of the ideas of political actors other than voters, such as bureaucrats and politicians. Normative political epistemologists could follow this lead (...) if they were to focus on the technocratic orientation of nearly all political actors in the West: that is, on their desire to solve social and economic problems. Since most technocratic policy is made by political elites, the reliability of elites' knowledge of the causes of and cures for social and economic problems is a natural topic for normative political epistemology.

The normative and metanormative pluralism that figures among core self-descriptions of democratic theory, which seems incompatible with democratic theorists’ practical ambitions, may stem from the internal logic of research traditions in the social sciences and humanities and in the conceptual structure of political theory itself. One way to deal productively with intradisciplinary diversity is to appeal to the idea of a meta-consensus; another is to appeal to the argument from cognitive diversity that fuels recent debates on epistemic democracy. For different (...) reasons, both strategies fail, such that a metatheoretical step aside may be desirable, one that entails modeling democratic theory after the public justification approach.
