An important theme in recent experimental philosophy is that certain judgements (e.g. our judgements involving intentional action and causation) exhibit a kind of normative penetration whereby, in spite of a not-obviously-normative subject matter, they turn out to be sensitive to, and co-vary with, our normative attitudes in interesting and surprising ways. We present the results of several new experimental studies that suggest that our judgements about feasibility also appear to exhibit this kind of normative penetration in at least some cases; (...) that the best explanation of it involves attributing to subjects a certain kind of extensional error that results from conflating the question at hand with another question that is more salient given their normative attitudes; and that these conclusions have significant, though not straightforward, implications for our understanding of both normative penetration and feasibility, respectively.

This paper provides a new argument for the relevance of empirical research to moral and political philosophy and a novel defense of the positive program in experimental philosophy. The argument centers on the idea that normative concepts used in moral and political philosophy can be evaluated in terms of their fruitfulness in solving practical problems. Empirical research conducted with an eye to the practical problems that are relevant to particular concepts can provide evidence of their fruitfulness along a number of (...) dimensions. An upshot of the argument is that philosophers should not only engage with but must also be involved in conducting experimental studies that examine the practical roles that normative concepts can play. Rather than just clearing the way for philosophical work to be done, the argument has the further implication that empirical research will be required to advance at least some important debates in moral and political philosophy.

We present evidence from a pre-registered experiment indicating that a philosophical argument––a type of rational appeal––can persuade people to make charitable donations. The rational appeal we used follows Singer’s well-known “shallow pond” argument (1972), while incorporating an evolutionary debunking argument (Paxton, Ungar, & Greene 2012) against favoring nearby victims over distant ones. The effectiveness of this rational appeal did not differ significantly from that of a well-tested emotional appeal involving an image of a single child in need (Small, Loewenstein, and (...) Slovic 2007). This is a surprising result, given evidence that emotions are the primary drivers of moral action, a view that has been very influential in the work of development organizations. We did not find support for our pre-registered hypothesis that combining our rational and emotional appeals would have a significantly stronger effect than either appeal in isolation. However, our finding that both kinds of appeal can increase charitable donations is cause for optimism, especially concerning the potential efficacy of well-designed rational appeals. We consider the significance of these findings for moral psychology, ethics, and the work of organizations aiming to alleviate severe poverty. (shrink)

Social contract theorists often take the ideal contract to be the agreement or bargain individuals would make in some privileged choice situation. Recently, experimental philosophers have explored this kind of decision-making in the lab. One rather robust finding is that the exact circumstances of choice significantly affect the kinds of social arrangements experimental subjects unanimously endorse. Yet prior work has largely ignored the question of which of the many competing descriptions of the original position subjects find most compelling. This paper (...) aims to address this gap, exploring how attractive experimental subjects find various characterizations of these circumstances of choice. We find evidence suggesting that no one choice situation can fulfill the role that social contract theorists have hoped it would play. We also find that, contrary to what some prominent social contract theorists have expected, there is no robust relationship between an individual’s ranking of distributive principles and their ranking of various descriptions of the original position. In conclusion, we discuss the broader implications of these results for political philosophy. (shrink)

Two main types of philosophical arguments have been given in support of the claim that the citizens of affluent societies have stringent moral duties to aid the global poor: “positive duty” arguments based on the notion of beneficence and “negative duty” arguments based on noninterference. Peter Singer’s positive duty argument (Singer 1972) and Thomas Pogge’s negative duty argument (Pogge 2002) are among the most prominent examples. Philosophers have made speculative claims about the relative effectiveness of these arguments in promoting attitudes (...) and behaviors that could lead to the alleviation of poverty. In this article we present the results of two empirical studies that evaluate these claims, and suggest that both arguments have a modest effect on people’s attitudes and behaviors regarding global poverty. In a replication of the second study, the negative duty argument, in particular, had a statistically significant effect on donations. We discuss the theoretical and practical significance of these results and suggest directions for further research on the role that philosophical arguments can play in engendering concern and action on pressing moral problems.

Empirical support is offered for the claim that the original Knobe effect, whereby our intentional action ascriptions exhibit certain asymmetries in light of our moral attitudes, can be successfully cancelled. This is predicted by the view that the Knobe effect can be explained in purely pragmatic terms (Adams and Steadman 2004a, 2004b, 2007). However, previous cancelling studies (Adams and Steadman 2007; Nichols and Ulatowski 2007) have failed to identify evidence of cancellability. The key to the successful cancelling strategy presented here (...) is to provide subjects with the opportunity to assent to statements that involve sufficiently strong forms of moral censure.

In the burgeoning philosophical literature on conceptual engineering improving our concepts is typically portrayed as the hallmark activity of the field. However, Herman Cappelen has challenged the idea that we can know how and why conceptual changes occur well enough to actively intervene in revising our concepts; the mechanisms of conceptual change are typically inscrutable to us. If the ‘inscrutability challenge’ is correct, the practical aspect of conceptual engineering may seem to be undermined, but I argue that endorsing such pessimism (...) would be a mistake. Even if the inscrutability challenge is correct, conceptual engineers often have good reasons to try to preserve existing concepts. I examine several cases where concept preservation is important and draw lessons about this activity for conceptual engineers. (shrink)

According to the traditional state sovereignty view in the ethics of immigration literature, societies have a great deal of latitude in determining and implementing their immigration policies. This view is typically defended by appealing to the rights of members of societies, for instance to political self-determination. Opponents of the view have often criticized its partiality to members, arguing that nonmembers can also make stringent demands on societies to be admitted and given the same treatment in matters of immigration policy as (...) other nonmembers. In this paper, I take a different approach to responding to the state sovereignty view. I argue that even if we grant the premise that the rights of members generally trump the rights of nonmembers in matters of immigration policy, societies are greatly constrained in setting their immigration policies by considerations of domestic justice. The considerations that I focus on involve relationships between members and nonmembers that hold due to a shared quality or set of qualities on the basis of which members identify with nonmembers. The argument appeals to premises and principles that defenders of the state sovereignty view are committed to but concludes that this view cannot serve as a satisfactory framework for the normative assessment of immigration policies.

Traditionally, moral philosophers have distinguished between doing and allowing harm, and have normally proceeded as if this bipartite distinction can exhaustively characterize all cases of human conduct involving harm. By contrast, cognitive scientists and psychologists studying causal judgment have investigated the concept ‘enable’ as distinct from the concept ‘cause’ and other causal terms. Empirical work on ‘enable’ and its employment has generally not focused on cases where human agents enable harm. In this paper, we present new empirical evidence to support (...) the claim that some important cases in the moral philosophical literature are best viewed as instances of enabling harm rather than doing or allowing harm. We also present evidence that enabling harm is regarded as normatively distinct from doing and allowing harm when it comes to assigning compensatory responsibility. Moral philosophers should be exploring the tripartite distinction between doing harm, allowing harm, and enabling harm, rather than simply the traditional bipartite distinction. Cognitive scientists and psychologists studying moral judgment, who have so far largely adopted the bipartite distinction in this area of research, should likewise investigate the tripartite distinction.

In the course of presenting a compelling and comprehensive framework for immigration justice, Brock addresses discriminatory immigration policies, focusing on recent attempts by the Trump administration to exclude Muslims from the U.S.. This essay critically assesses Brock’s treatment of the issue, and in particular the question of what made the Muslim ban and similar policies unjust. Through examining these issues, further questions regarding the immigration justice framework on offer arise.

The view that innocent beneficiaries of injustice bear special duties to victims of injustice has recently come under attack. Luck egalitarian theorists have argued that thought experiments focusing on the way innocent beneficiaries should distribute the benefits they’ve received provide evidence against this view. The apparent special duties of innocent beneficiaries, they hold, are wholly reducible to general duties to compensate people for bad brute luck. In this paper we provide empirical evidence in defense of the view that innocent beneficiaries (...) have genuine special duties to victims of injustice. Through a series of four experiments, we show that judgments about the kinds of cases that luck egalitarian critics have provided do not undermine but rather support this view. We also explore a number of other questions that theorists working in this area have yet to discuss and provide suggestions for further research on the moral significance of benefiting from injustice.

This article highlights two interlocking themes in moral and political philosophy in the Kantian tradition and examines their import for issues in international relations. First, I examine how constructivist interpretations of Kantian moral theory can inform an understanding of Kant’s Perpetual Peace and passages in other key texts that deal with international relations. Second, drawing on the constructivist tradition, I examine Kant’s remarks on the dependency of domestic justice on international justice. By bringing these two themes together, I put forward (...) a Kantian view of international relations that emphasizes the role of morality in resolving practical problems at the international level and draws attention to the ways in which solving problems of domestic justice is contingent on also solving problems of international justice. Each of these points provides a Kantian response to, and the second puts pressure on, realist views in international relations. (shrink)

Discriminatory attitudes towards Muslim refugees are common in liberal democracies, and Muslim citizens of these countries experience high rates of discrimination and social exclusion. Uniting these two facts is the well-known phenomenon of Islamophobia. But the implications of overlapping discrimination against citizens and non-citizens have not been given sustained attention in the ethics of immigration literature. In this paper, I argue that liberal societies have not only duties to discontinue refugee policies that discriminate against social groups like Muslims, but remedial (...) duties to citizens who are in these social groups to adopt a more welcoming stance towards the groups that they are in. Further, I argue that a fitting way of adopting this more welcoming stance is to give refugees in these groups preferential treatment in asylum and resettlement. (shrink)

This article argues that citizens have a basic right to invite family members and spouses into their society on the basis of Rawlsian egalitarian premises. This right is argued to be just as basic as other recognized basic rights, such as freedom of speech. The argument suggests further that we must treat immigration and family reunification, in particular, as central issues of domestic justice. The article also examines the implications of these points for the importance of immigration in liberal domestic (...) justice and suggests avenues for further research on the interplay of considerations of justice towards citizens and non-citizens.

Liberal societies typically prefer relatives and spouses of their members over other prospective immigrants seeking admission. Giving this preferential treatment to only certain categories of relationships requires justification. In this paper, I provide a defense of a category-based system for "unification admissions," non-members seeking admission for the purpose of living in the same society with members on a stable basis, that is compatible with liberalism and, in particular, does not violate the requirement of liberal neutrality. This defense does not commit (...) liberal theorists to the traditional state sovereignty view on immigration, according to which societies have wide latitude to exclude immigrants as they see fit, and shows that, contra Ferracioli, societies are not required to treat relatives, spouses, friends, and creative partners of their members on a par in matters of immigration policy.

This article compares the moral significance of two types of immigration, that which is based on the unification of citizens and non-citizens and that which is based on the skilled labor needs of the receiving society. I assess the interests of both citizens and non-citizens affected by each of these types of inflows and argue that unification admissions should be given priority over skilled workers but states retain a qualified moral permission to incentivize skilled worker migration.
