This article examines two questions about scientists’ search for knowledge. First, which search strategies generate discoveries effectively? Second, is it advantageous to diversify search strategies? We argue pace Weisberg and Muldoon, “Epistemic Landscapes and the Division of Cognitive Labor”, that, on the first question, a search strategy that deliberately seeks novel research approaches need not be optimal. On the second question, we argue they have not shown epistemic reasons exist for the division of cognitive labor, identifying the errors that led (...) to their conclusions. Furthermore, we generalize the epistemic landscape model, showing that one should be skeptical about the benefits of social learning in epistemically complex environments. (shrink)

Geoffrey Rose's ‘prevention paradox’ occurs when a population-based preventative health measure that brings large benefits to the community – such as compulsory seatbelts, a ‘fat tax’, or mass immunisation – offers little to each participating individual. Although the prevention paradox is not obviously a paradox in the sense in which philosophers understand the term, it does raise important normative questions. In particular, should we implement population-based preventative health measures when the typical individual is not expected to gain from them? After (...) canvassing other attempts to address the paradox, I argue that what is significant about the prevention paradox is that it involves intra-personal trade-offs; the costs and benefits of the choice to implement or not implement a preventative health measure fall on the same individuals. The intra-personal nature of these trade-offs has two implications. First, the solutions to the paradox proposed by other authors are deficient. Second, the policy choice to not implement some preventative health measures can be normatively justified. (shrink)

Multiple-vote majority rule is a procedure for making group decisions in which individuals weight their votes on issues in accordance with how competent they are on them. When individuals are motivated by the truth and know their relative competence on different issues, multiple-vote majority rule performs nearly as well, epistemically speaking, as rule by an expert oligarchy, but is still acceptable from the point of view of equal participation in the political process.

A standard view of trust sees trust as intimately related to reliance; on this standard view, trust is reliance plus some other factor. A significant literature has now developed that seeks to explain what factor, in addition to reliance, serves to distinguish cases of trust from cases of mere reliance. I argue that this approach to the analysis of trust is misguided. Although reliance, properly understood, frequently accompanies trust, reliance is not a necessary condition of trust.

Christian List and Philip Pettit have recently developed a model of group agency on which an autonomous group agent can be formed, by deductive inference, from the beliefs and preferences of the individual group members. In this paper I raise doubts as to whether this type of group agent is a moral agent. The sentimentalist approach to moral responsibility sees a constitutive role for moral emotions, such as blame, guilt, and indignation, in our practices of attributing moral responsibility. These moral (...) emotions are important for the alignment of moral understandings, and for valuing other members of the moral community. I argue that while the intentional objects of beliefs and preferences are propositions, the intentional objects of moral emotions are other agents. Because agents are not subject to rules of inference, we cannot generate group agent emotions—such as guilt—in the same way as we can generate group agent beliefs and preferences. And because the group agents lack moral emotions, we have reason to resist treating them as moral agents. (shrink)

I aim to show that the failure of the California Class Size Reduction initiative highlights an important class of situations in the application of evidence to policy. There are some circumstances in which the implementation of a policy will be self-defeating. The introduction of the factor assumed to have causal efficacy into the target population can lead to changes in the conditions of the target population that amount to interfering factors. Because these interfering factors are a direct result of the (...) policy implementation they should be relatively easy to predict, and so part of the tricky issue of judging where evidence is relevant should in some circumstances be relatively straightforward. -/- The failure of the California Class Size Reduction initiative also shows how important it is to identify the correct causal factor. The more accurate the attribution of causality, the less susceptible it will be to interfering factors and breaks in the causal chain. (shrink)

The standard epistemic justification for inclusiveness in political decision making is the Condorcet Jury Theorem, which states that the probability of a correct decision using majority rule increases in group size (given certain assumptions). Informally, majority rule acts as a mechanism to pool the information contained in the judgements of individual agents. I aim to extend the explanation of how groups of political agents track the truth. Before agents can pool the information, they first need to find truth-conducive information. Increasing (...) group size is also important in the initial search for truth-conducive information. (shrink)

This article address the ways in which contemporary psychologists might usefully engage in a dialogue with Catholic philosophers and theologians influenced by the thought of St. Thomas Aquinas. The specific point of common agreement and vision between these diverse approaches lies in the general notion that human action is directed toward an end which the individual judges to be good in some sense. Despite the considerable differences in foundational issues, boththe clinical psychologist and Thomist are perhaps able to come to (...) a constructive, common vision around the notion that all human action is directed toward the achievement of some good.

The warrant for investigating the relationship between Augustine and narrative ethics is prompted, among other things, by a consideration of the appeals to Augustine among a diversity of views within the vast field of narrative ethics. Disparate thinkers from distinctively different backgrounds and with different motives and purposes, while all sharing an interest in the category of "narrative," also share a common interest in employing Augustine's Confessions in their efforts. Thus the question emerges as to what it is about this (...) ancient text which so readily serves such diverse yet unified purposes. ;After a thorough investigation and evaluation of the appeals to Augustine among a sampling of contemporary narrativists I turn to the Confessions directly. I argue that an examination of the anti-Manichaean aspects of its composition yield important insights regarding its usefulness in the efforts of contemporary narrativists. Specifically, I argue that implicit in this work is a theology of creation which supplies essential foundations to the contemporary discussion of narrative ethics. (shrink)
