Francesco Guala has developed some novel and radical ideas on the problem of external validity, a topic that has not received much attention in the experimental economics literature. In this paper I argue that his views on external validity are not justified and the conclusions which he draws from these views, if widely adopted, could substantially undermine the experimental economics enterprise. In rejecting the justification of these views, the paper reaffirms the importance of experiments in economics.

Humphreys and Forde argue that semantic memory is divided into separate substores for different kinds of information. However, the neuro-imaging results cited in support of this view are inconsistent and often methodologically and statistically unreliable. Our own data indicate no regional specialisation as a function of semantic category or domain and support instead a distributed unitary account.

Résumé Le problème de Duhem-Quine a été considéré comme un problème majeur de la philosophie des sciences et a donné lieu au déploiement de nombreux efforts pour tenter de le circonvenir ou d’affaiblir ses implications. Plus récemment, le problème est devenu une question majeure au sein de la méthodologie de l’économie expérimentale. Dans cet article, l’auteur soutient que la plupart de ces discussions soit sacrifient trop du pouvoir explicatif de la science, soit ne réussissent pas à traiter proprement du problème. (...) Dans le prolongement de discussions récentes en philosophie des sciences, on peut voir que le meilleur moyen de traiter du problème est de critiquer la conception même de la science développée par Quine.

We provide and interpret a new measure independent characterization of the Gödel speed-up phenomenon. In particular, we prove a theorem that demonstrates the indifference of the concept of a measure independent Gödel speed-up to an apparent weakening of its definition that is obtained by requiring only those measures appearing in some fixed Blum complexity measure to participate in the speed-up, and by deleting the “for all r” condition from the definition so as to relax the required amount of speed-up. We (...) interpret our results as correlating the relative difficulty of mechanically recognizing theories with the relative power and the relative abstractness of the theories. We conclude by providing two open problems concerning possible similarities and relationships between the Blum speedability and Gödel speed-up phenomena. MSC: 03D15, 03F20. (shrink)

We study the measure independent character of Godel speed-up theorems. In particular, we strengthen Arbib's necessary condition for the occurrence of a Godel speed-up [2, p. 13] to an equivalence result and generalize Di Paola's speed-up theorem [4]. We also characterize undecidable theories as precisely those theories which possess consistent measure independent Godel speed-ups and show that a theory τ 2 is a measure independent Godel speed-up of a theory τ 1 if and only if the set of undecidable sentences (...) of τ 1 which are provable in τ 2 is not recursively enumerable.

In this paper we interpret a characterization of the Gödel speed-up phenomenon as providing support for the ‘Nagel-Newman thesis’ that human theorem recognizers differ from mechanical theorem recognizers in that the former do not seem to be limited by Gödel's incompleteness theorems whereas the latter do seem to be thus limited. However, we also maintain that (currently non-existent) programs which are open systems in that they continuously interact with, and are thus inseparable from, their environment, are not covered by the (...) above (or probably any other recursion-theoretic) argument.

In normative multi-agent systems, the question of “how an agent identifies norms in an open agent society” has not received much attention. This paper aims at addressing this question. To this end, this paper proposes an architecture for norm identification for an agent. The architecture is based on observation of interactions between agents. This architecture enables an autonomous agent to identify prohibition norms in a society using the prohibition norm identification (PNI) algorithm. The PNI algorithm uses association rule mining, a (...) data mining approach to identify sequences of events as candidate norms. When a norm changes, an agent using our architecture will be able to modify the norm and also remove a norm if it does not hold in the society. Using simulations of a park scenario we demonstrate how an agent makes use of the norm identification framework to identify prohibition norms. (shrink)

The purpose of this article is to show that animal rights are not necessarily at odds with the use of animals for research. If animals hold basic moral rights similar to those of humans, then we should consequently extend the ethical requirements guiding research with humans to research with animals. The article spells out how this can be done in practice by applying the seven requirements for ethical research with humans proposed by Ezekiel Emanuel, David Wendler and Christine Grady to (...) animal research. These requirements are i) social value, ii) scientific validity, iii) independent review, iv) fair subject selection, v) favorable risk-benefit ratio, vi) informed consent, and vii) respect for research subjects. In practice, this means that we must reform the practice of animal research to make it more similar to research with humans, rather than completely abolish the former. Indeed, if we banned animal research altogether, then we would also deprive animals of its potential benefits – which would be ethically problematic. (shrink)

Digital contact tracing, in combination with widespread testing, has been a focal point for many plans to “reopen” economies while containing the spread of Covid‐19. Most digital contact tracing projects in the United States and Europe have prioritized privacy protections in the form of local storage of data on smartphones and the deidentification of information. However, in the prioritization of privacy in this narrow form, there is not sufficient attention given to weighing ethical trade‐offs within the context of a public (...) health pandemic or to the need to evaluate safety and effectiveness of software‐based technology applied to public health.

Within medical ethics, there is widespread agreement that morally valid consent includes an understanding condition. Disagreement centers on what is meant by that understanding condition. Tom Dougherty proposed that this understanding condition should be divided into the two mutually exclusive categories of descriptive information and contextual information. Further, Dougherty argues that each type of information is necessary to satisfy the understanding condition. In contrast, I argue that when the deontic aspect of valid consent is in view, each type of information (...) can be sufficient to satisfy the understanding condition on its own. Moreover, by analyzing delegation, which is conceptually related to consent since both are morally transformative actions, I show that delegation often depends not on descriptive or contextual information but on trust. So, I argue that trustworthiness can also be a type of information that does the same work as descriptive and contextual information in satisfying the understanding condition for valid consent.

In this chapter, it is argued that some animal shelters fulfill the conditions that make triage protocols necessary, namely, the operation with limited financial budgets, space, medical resources, and staff. It is suggested that requirements presented for triage in humans can be fruitfully applied to the context of animal shelters. The focus lies on the criteria of maximizing benefit, justice, medical criteria, life-span considerations, fair decision-making, patient will, re-evaluation of triage decisions and changes in the therapeutic goal, and burden of (...) triage and staff support. The establishment of triage protocols for shelters will make the decision-making process less arbitrary, fairer, and more transparent. Furthermore, it is argued that, in situations where disagreement persist among shelter staff, an external Ethics Board could be called in to help analyze and potentially resolve some of the remaining ethical issues.

Although it seems that ethics and religion should be related, past research suggests mixed conclusions on the relationship. We argue that such mixed results are mostly due to methodological and conceptual limitations. We develop hypotheses linking Cornwall et al.’s (1986, Review of Religious Research, 27(3): 266–244) religious components to individuals’ willingness to justify ethically suspect behaviors. Using data on 63,087 individuals from 44 countries, we find support for three hypotheses: the cognitive, one affective, and the behavioral component of religion are (...) negatively related to ethics. Surprisingly, one aspect of the cognitive component (i.e., belief in religion) shows no relationship. Implications for research and practice are discussed. (shrink)

There is broad agreement that humans can be wronged independently of their incurring any harm, that is, when their welfare is not affected. Examples include unnoticed infringements of privacy, ridiculing unaware individuals, or disregarding individuals’ autonomous decision-making in their best interest. However, it is less clear whether the same is true of animals—that is, whether moral agents can wrong animals in situations that do not involve any harm to the animals concerned. In order to answer this question, I concentrate on (...) the illustrative case of treating animals in a demeaning yet harmless way that would be disrespectful if humans were concerned. I discuss whether such actions are permissible or unjustifiably discriminatory from a moral point of view. I conclude that moral agents cannot directly wrong animals without harming them and thus do not owe it to a particular animal to refrain from such actions. However, if the actions increase the likelihood that animal abuse will occur, this presents a strong indirect reason against performing them. Thus, the reasons for refraining from such actions are merely indirect rather than direct. (shrink)

While human vulnerability has been discussed for some time in the contemporary philosophy and bioethics literature, animal vulnerability has received less attention. In this article, I investigate whether the concept of vulnerability, as it is currently used in bioethics, can be meaningfully extended to animals. Furthermore, I discuss the ethical implications of ascribing vulnerability to animals and I show what vulnerability discourse can add to debates on animal ethics. In a first step, I analyse the conditions of vulnerability ascription. By (...) taking as my basis the definition of vulnerability presented by Martin, Tavaglione and Hurst, I demonstrate that some animals fulfil the conditions of vulnerability ascription. I explore the ethical implications of vulnerability ascriptions in three domains: livestock farming, animal experimentation, and animals living in the wild. I argue that many groups of animals currently qualify as particularly vulnerable and should be afforded special protection so that they receive what they are due. I conclude by outlining the differences between vulnerability and sentience ascriptions: while sentience is a sufficient reason to ascribe moral status to a being, vulnerability draws our attention to those who are more likely to be denied what they are due.

According to Williams, human facially expressed pain, and its perception by conspecifics, is generated by evolved mechanisms. We argue that a key variable – sex (male, female) – needs to be considered for a complete theory of pain expression and perception. To illustrate, we cite findings on sex differences in pain and pain perception, and in crying and crying responsiveness.

In this chapter, Angela Martin explores what moral agents owe to insects as a potential food source. Given that no scientific consensus has yet been reached on the question of whether or not insects are sentient, she investigates three assumptions on that head, along with their moral implications: i) the view that insects are definitely not sentient; ii) the view that there is uncertainty about insect sentience; and iii) the view that insects are definitely sentient. Martin argues that (...) under assumptions i) to iii), there are no strong reasons against eating insects. She thus concludes that it is morally permissible (although not morally obligatory) to use insects for human consumption. (shrink)

Human and animal interests are often in conflict. In many situations, however, it is unclear how to evaluate and weigh competing human and animal interests, as the satisfaction of the interests of one group often inevitably occurs at the expense of those of the other group. Human-animal conflicts of this kind give rise to ethical questions. If animals count morally for their own sake, then we must ask in which cases the satisfaction or frustration of the interests of humans and (...) animals in conflict situations is justified or unjustified from an ethical perspective. In this article, we argue that limited aggregation accounts represent a promising means for resolving interspecies conflicts. The reason for this is that they can appropriately consider the qualitative relevance of interests, their relative importance to each other, and the number of individuals affected. For our argument, we start from the premise that animals count morally for their own sake, albeit to a lesser extent than humans. That is, we accept the view that animals may be used, for example, as a source of food or in animal research. However, as we will show, many basic interests of animals are sufficiently similar to human interests and can thus be compared to them. Hence, they ought to be aggregated in cases of conflict with human interests. We illustrate our account and its practical implications with the real-world example of a human-animal conflict during the outbreak of a zoonotic disease among farmed animals. We conclude that, in many cases, animal interests ought to be given more importance than they currently receive, which includes distributing the burdens and risks of farming practices more fairly.

Philosophy has much to offer psychiatry, not least regarding ethical issues, but also issues regarding the mind, identity, values, and volition. This has become only more important as we have witnessed the growth and power of the pharmaceutical industry, accompanied by developments in the neurosciences. However, too few practising psychiatrists are familiar with the literature in this area. -/- The Oxford Handbook of Philosophy and Psychiatry offers the most comprehensive reference resource for this area ever published. It assembles challenging and (...) insightful contributions from key philosophers and others to the interactive fields of philosophy and psychiatry. Each contributions is original, stimulating, thorough, and clearly and engagingly written - with no potentially significant philosophical stone left unturned. Broad in scope, the book includes coverage of several areas of philosophy, including philosophy of mind, science, and ethics. For philosophers and psychiatrists, The Oxford Handbook of Philosophy and Psychiatry is a landmark publication in the field - one that will be of value to both students and researchers in this rapidly growing area.

Summary Coursework is an integral part of the GCSE framework, valued for its motivational qualities and its curricular validity. It is a common perception, widely reported in the national press and educational media, that coursework can be held at least partly accountable for differential performances at GCSE; coursework, it is argued, advantages girls. This article reports on an analysis of data arising from a project which offered an opportunity to study current and post-GCSE students’ perceptions of coursework. The outcomes indicate (...) that, when categorised by their relative levels of attainment, girls’ and boys’ perceptions show limited evidence of homogeneity. In other words, to suggest that girls’ and boys’ perceptions of coursework are a function of gender is a gross over-simplification. Other factors are at play and further, more specific and tailored research is essential if we are to understand how best to optimise the benefits that are claimed for coursework. (shrink)
