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)

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.

This article critically assesses the moral arguments that speak in favour of three consumer options: buying local food, buying global (non‐local) food, and buying global food while also purchasing carbon offsets to mitigate the environmental impact of food transportation. We argue that because the offsetting option allows one to provide economic benefits to the poorest food workers while also mitigating the environmental impact of food transportation it is morally superior to the alternatives.

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)

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.Send article to KindleTo send this article to your (...)

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)
