The chapter addresses a problem that affects both regulatory and tort law efforts to control exposure to carcinogens. What should be done when a disease may be the result of “joint causation”? That is, there are two or more possible causes, each of which alone would be sufficient to explain the presence of disease. Tort law has developed a solution to this problem which has recently been adopted by some courts considering toxic torts. However, the problem of joint causation and (...) more general issues raised by causation reveal weaknesses in tort law for compensating victims exposed to toxic substances. Because of these and other problems with tort law, administrative institutions at least _in principle_ may better control human exposure to toxic substances. However, such institutions face enough practical problems that they will not always reliably protect people from toxic substances. In the end, the chapter argues, there are several good reasons for preferring administrative agencies to tort law to provide environmental health protection. However, these theoretical advantages should not blind us to some of the political shortcomings of relying on administrative agencies. For that reason such agencies should not replace tort law, which can continue to serve a backup function to the agencies in our legal system. (shrink)

Scientists may sometimes generalize from their samples to broader populations when they have not yet sufficiently supported this generalization. Do such hasty generalizations also occur in experimental philosophy? To check, we analyzed 171 experimental philosophy studies published between 2017 and 2023. We found that most studies tested only Western populations but generalized beyond them without justification. There was also no evidence that studies with broader conclusions had larger, more diverse samples, but they nonetheless had higher citation impact. Our analyses (...) reveal important methodological limitations of many experimental philosophy studies and suggest that philosophical training may not protect against hasty generalizations. (shrink)

This chapter provides an overview of the topics discussed in the book and likens the assessment of toxic substances to the experience of peering through a glass darkly. The work is divided into five main chapters and these chapters give an exploration of the scientific background necessary for understanding the subject. The book examines the practice of predicting risks from animal bioassays and addresses the normative implications of the scientific uncertainties in risk assessment. In addition, the book examines problems in (...) the statistics of human epidemiological studies and animal bioassay and considers practical evidence-gathering problems, theoretical difficulties, and traditional practices in interpreting epidemiological studies and offers an alternative to traditional practices.

This chapter argues against the shift in paradigm in favor of scientific evidence in tort law cases. Recent proposals, seeking to require more demanding scientific evidence in toxic tort (and other) suits, are mistaken because these seem to impose a universal standard of evidence for quite different institutions—with the risk of distorting existing reasonable tort law relationships, and erring on the side of exclusion rather than admission of evidence. Since the plaintiff bears the burden of production, requiring that this be (...) met by proof equivalent to the criminal law's “beyond a reasonable doubt,” requirement, as some have argued, this substantially distorts the balance of interests between plaintiff and defendant. The appropriate paradigm is not that for scientific practice but the traditional tort law standard of evidence articulated in _Ferebee v. Chevron Chemical Co._, which said that the appropriate standard is not scientific certainty but “legal sufficiency.” The paradigm of choice in torts is in a sense inclined to retain much of the status quo. (shrink)

This chapter continues the argument of why ideal levels of scientific accuracy should not be applied in torts and administrative law by focusing on two issues. Firstly, the standards of evidence ought to be appropriate to the institutional context. Secondly, justice requires that priority be given to avoiding false negatives and underregulation. One requires justification of the epistemic presupposition, the other, justification of the underlying moral view. The first issue states that the burden of proof that must be satisfied in (...) order to make a particular institutional decision will depend at least in large part upon the kinds of mistakes one seeks to avoid. For example, criminal law stringently protects against convicting innocent people. To avoid this, the equivalent of false positives, the state must overcome a high burden of proof to establish its case. By contrast, in screening patients for life-threatening diseases we might seek very much to avoid missing someone who has the disease, to avoid false negatives. The second issue comes from the premise that in the common law of torts, distributive issues are not decided as a matter of consistent theory but are developed by means of case-by-case adjudication between two parties. Although judges try to produce consistent decisions over time, but they do not always succeed. If the law is not necessarily consistent, it is especially important to have a better view of more fundamental and consistent normative principles to guide epistemology. (shrink)

The chapter discusses some of the risk assessment issues that arise in administrative agencies charged with regulating carcinogens. It is argued that present assessment strategies, as well as some recommended by commentators, both of which are inspired by the paradigm of research science—the use of careful, detailed, science-intensive, substance-by-substance risk assessments—paralyze regulation. The identification, assessment, and regulation of potential carcinogens are all too slow to evaluate adequately the existing universe of 50,000–100,000 chemical substances, and the 1,000–1,500 new ones that are (...) added each year. Thus, for identified carcinogens we need to adopt something like the expedited approximation procedures, which permit faster evaluation of potentially toxic substances. Alternative approaches to regulatory science which acknowledge and use normative considerations to guide assessment procedures and which recognize the importance of the rate of evaluation will expedite risk assessments and reduce regulatory false negatives and underregulation. (shrink)

This chapter provides some scientific background of risk assessment and sets up some of the institutional questions concerning the appropriate evidentiary standards needed within torts and administrative law to establish the requisite harms or risks of harm. The discussion here focuses on animal bioassays and human epidemiological studies, two aspects of carcinogen risk assessment relied upon in regulatory institutions to ascertain risks to human beings. The best evidence that proves that a substance causes cancer to human beings is provided by (...) _well-done_ epidemiological studies with large samples and sufficient follow-up. However, the chapter begins by considering animal studies, which is the evidence much more frequently relied upon by regulatory agencies, although it is less typically used in tort law and some jurisdictions give it little credence. There are uncertainties in animal bioassays which are large enough such that two different researchers using exactly the same data points from an animal study can come to much different conclusions.

This article maintains that an important class of scientific generalizations should be reinterpreted: they have typically been understood as ceteris paribus laws, but are, in fact, generics. Four arguments are presented to support this thesis. One argument is that the interpretation in terms of ceteris paribus laws is a historical accident. The other three arguments draw on similarities between these generalizations and archetypal generics: they come with similar inferential commitments, they share a syntactic form, and the existing theories (...) to make sense of them are alike. Once these generalizations are properly understood as generics, the recent cognitive approach to generics can be extended to the study of the relevant sciences. The last section indicates ways in which this extension is fruitful for the two strands of research that we combine: the philosophy of science literature on generalizations and the semantics literature on generics.

In this paper we present the development from paradoxism to neutrosophy, which gave birth to neutrosophic set and logic and especially to NeutroAlgebraic Structures (or NeutroAlgebras) and AntiAlgebraic Structures (or AntiAlgebras) that are generalizations and alternatives of the classical algebraic structures.

Species in biology are traditionally perceived as kinds of organisms about which explanatory and predictive generalizations can be made, and biologists commonly use species in this manner. This perception of species is, however, in stark contrast with the currently accepted view that species are not kinds or classes at all, but individuals. In this paper I investigate the conditions under which the two views of species might be held simultaneously. Specifically, I ask whether upon acceptance of an ontology of (...) species as diachronic segments of the tree of life species can perform the epistemic role of kinds of organisms to which explanatory and predictive generalizations apply. I show that, for species-level segments of the tree of life, several requirements have to be met before the performance of this epistemic role is possible, and I argue that these requirements can be met by defining species according to the Composite Species Concept proposed by Kornet and McAllister in the 1990s.

It is well known that Gödel’s incompleteness theorems hold for ∑1-definable theories containing Peano arithmetic. We generalize Gödel’s incompleteness theorems for arithmetically definable theories. First, we prove that every ∑n+1-definable ∑n-sound theory is incomplete. Secondly, we generalize and improve Jeroslow and Hájek’s results. That is, we prove that every consistent theory having ∏n+1set of theorems has a true but unprovable ∏nsentence. Lastly, we prove that no ∑n+1-definable ∑n-sound theory can prove its own ∑n-soundness. These three results are generalizations of (...) Rosser’s improvement of the first incompleteness theorem, Gödel’s first incompleteness theorem, and the second incompleteness theorem, respectively.

Generalizations, such as “ducks are birds” and “ducks carry avian flu,” are a common way of conveying information about the world, yet their implied prevalence—how broadly they should be applied—can vary widely. To interpret how broadly a generalization should be applied, listeners rely on prior knowledge. Listeners who have considerable experience (“experts”) with the subject being discussed may thus interpret a generalization differently than those without such experience (“novices”). In the present study, we investigated the ways in which experts (...) and novices differ in how they interpret generalizations, using the esport League of Legends as a cultural microcosm. In the process, we investigated the extent to which expert listeners discount generalizations with which they disagree. We found that novices tended to interpret generalizations more broadly than experts, with only experts adjusting their interpretations based on the context. We also investigated whether expert speakers, when addressing novices, avoid generalizations that novices are likely to interpret differently. In line with research investigating the curse of knowledge and the challenge of designing utterances for specific audiences, we found that speakers did not adjust their use of generalizations when explicitly told that their audience was inexperienced. Taken together, these results point to novice listeners interpreting generalizations as applying more broadly than expert speakers intend. Future research can help clarify the practical impact of such a mismatch by examining how generalizations are used in relation to speakers' and listeners' goals. (shrink)

Many ethical frameworks require artificial intelligence (AI) systems to be explainable. Explainable AI (XAI) models are frequently tested for their adequacy in user studies. Since different people may have different explanatory needs, it is important that participant samples in user studies are large enough to represent the target population to enable generalizations. However, it is unclear to what extent XAI researchers reflect on and justify their sample sizes or avoid broad generalizations across people. We analyzed XAI user studies (...) (N = 220) published between 2012 and 2022. Most studies did not offer rationales for their sample sizes. Moreover, most papers generalized their conclusions beyond their target population, and there was no evidence that broader conclusions in quantitative studies were correlated with larger samples. These methodological problems can impede evaluations of whether XAI systems implement the explainability called for in ethical frameworks. We outline principles for more inclusive XAI user studies.

Some propositions are true, and it is true that some propositions are true. Each of these facts looks like an impeccable ground of the other. But they cannot both ground each other, since grounding is asymmetric. This paper explores two new diagnoses of this much discussed puzzle. The tools of higher-order logic are used to show how both diagnoses can be fleshed out into strong and consistent theories of grounding. These theories of grounding in turn demand new theories of the (...) granularity of propositions, properties, and relations. Even those who are uninterested in grounding should take seriously these pictures of reality’s logical structure, which are in many ways reminiscent of Russell’s and Wittgenstein’s logical atomism.

I argue that inferences from highly probabilifying racial generalizations are not solely objectionable because acting on such inferences would be problematic, or they violate a moral norm, but because they violate a distinctively epistemic norm. They involve accepting a proposition when, given the costs of a mistake, one is not adequately justified in doing so. First I sketch an account of the nature of adequate justification—practical adequacy with respect to eliminating the ~p possibilities from one’s epistemic statespace. Second, I (...) argue that inferences based on demographic generalizations tend to disproportionately expose group members to the risks associated with mistakenly assuming stereotypical propositions, and so magnify the wrong involved in relying on such inferences without adequate justification.

Aspects of a formal theory of approximate generalizations, according to which they have degrees of truth measurable by the proportions of their instances for which they are true, are discussed. The idealizability of laws in theories of fundamental measurement is considered: given that the laws of these theories are only approximately true "in the real world", does it follow that slight changes in the extensions of their predicates would make them exactly true?

An ongoing debate in comparative research is about whether we should see cultural diversities as manifestations of essential differences or as superficial variations on a universal blueprint. Edward Slingerland has pointed to cognitive science and the use of embodied metaphors to emphasize the universality of concept formation and cognition across cultures. He suggests that this should quiet the “cultural essentialists” who take fundamental differences in Eastern and Western thinking as their starting points. Michael Puett has also leveled a critique of (...) cultural essentialism in support of a presuppositionless approach, and Slingerland’s conclusions seem to offer him support. However, I will argue that even if all modern humans are broadly similar in metaphor use and cognitive processes, research in the humanities must continue to account for the differences implied by the particular metaphors employed and emphasized in diverse traditions. I contend that responsible hermeneutic practice does this through provisional, yet indispensable, generalizations. (shrink)

Epidemiology studies the variations in health in populations, according to different factors and parameters. In this field, probability and statistics are used in order to provide a quantitative description and analysis of the variations in exposure and disease, as well as of the effects of possible preventatives. Thus, one goal of epidemiology is to establish statistical generalizations about health and disease in populations. Consequently, it is important to understand how statistical generalizations are established and what use one can (...) make of them to establish medical knowledge or to design public health policies.

Machamer, Darden, and Craver argue that causal explanations explain effects by describing the operations of the mechanisms which produce them. One of this paper’s aims is to take advantage of neglected resources of Mechanism to rethink the traditional idea that actual or counterfactual natural regularities are essential to the distinction between causal and non-causal co-occurrences, and that generalizations describing natural regularities are essential components of causal explanations. I think that causal productivity and regularity are by no means the same (...) thing, and that the Regularists are mistaken about the roles generalizations play in causal explanation. Humean, logical empiricist, and other Regularist accounts of causal explanation have had the unfortunate effect of distracting philosophers’ from important non-explanatory scientific uses of laws and lesser generalizations which purport to describe natural regularities. My second aim is to characterize some of these uses, illustrating them with examples from neuroscientific research. (shrink)

Source: Author: Leonila C. Crisostomo, Ma. Teresa G. Generales, Amelita L. de Guzman The primary purpose of this study is to ascertain the benefits of the National Service Training Program implementation and to identify the problems encountered by its implementers. Results showed that the benefits derived from the program were topped by enhancement of skills on basic leadership with emphases on the ability to listen and ability to communicate which were rated very important and very much benefited among other training (...) aspects of the program. Results also revealed that students are aware of the importance of physical, mental and social health as well as the observance of proper hygiene for overall sense of well-being. Although recreation is one aspect that the respondents find important, appreciation of it underscores the need to have more time for assignments and projects as most of the respondents are enrolled in their respective courses with 29 units, making them unable to appreciate the perks of involving themselves into various recreational activities. Problems in the implementation showed lack of provision of materials and equipment and of budgetary allocation which rendered full implementation weak as students and faculty involved in the community immersion have to rely on their own resources, in addition to the indifference and passivity of the local government officials. Based on the findings, the researchers recommended that: the school administrators need to allocate adequate budget for materials and equipment; periodic faculty development trainings and; to look into the passive attitude of the local officials to ensure that implementation NSTP projects will benefit both clients and implementers. ]]>.

At the beginning of the pandemic, many music ensembles had to stop their activities due to the confinement. While some found creative ways to start making music again with the help of technologies, the transition from “real” rehearsals to “online” rehearsals was challenging, especially among older amateur musicians. The aim of this case study was to examine the effects of this transition on three community band conductors and three older amateur musicians. Specific objectives were to explore intergenerational relationships to support (...) online group music-making; digital literacy and access in later life; and online music-making in a COVID-19 context. Semi-structured interviews were conducted and theoretical thematic analysis was undertaken. Results were analyzed from the conductors’ and older musicians’ perspectives, and common trends were combined to facilitate interpretation. The first theme showed that being part of an intergenerational ensemble contributed positively to the learning experience online. The second theme demonstrated that because both conductors and musicians were new to the online rehearsals, it contributed to attenuate the age-related digital divide that may have been observed in other studies. Regarding access in later-life, older musicians reported benefits associated with rehearsing online, specifically in terms of distance/commute, time, energy, and cost. However, for those who did not already have internet and electronic devices, the cost of acquiring all the necessary equipment to make music online could have been too high. Finally, the third theme revealed that musicians appreciated the opportunity to make music online and indicated that it was definitely better than having nothing, especially for its social aspects. In conclusion, while participants noted several challenges associated with online music-making, they were also appreciative of the opportunity to continue making music at a time when in-person rehearsals were not possible. Pedagogical implications are discussed, specifically the importance of the support network, of meeting people where they are, of learning to adapt, and of collaborative teaching. (shrink)

In defending the scientific legitimacy of ceteris paribus qualified causal generalizations, we situate and specify the reference of the ceteris paribus proviso within a fundamental causal framework consisting of causal agents, pathways of influence, mediators, moderators, and causal consequences. In so doing, we provide an explication of the reference and utility of the ceteris paribus proviso in terms of mediators and moderators as these constitute the range of factors that can impinge on the relation between cause and effect. We (...) argue that the conceptual causal roadmap embodied by the ceteris paribus qualification serves as a schematic template for the ongoing identification of causally relevant factors and plays an indispensable heuristic role in advancing scientific inquiry into causal relations. We then provide guidelines for differentiating between acceptable and unacceptable uses of ceteris paribus and describe how mediators and moderators conceptually encompassed by the ceteris paribus proviso can be employed in evaluating the meaning and acceptability of proposed ceteris paribus causal generalizations, as well serve as a guide to investigators in the process of designing studies to identify a causal agent, mediators, moderators, pathways of influence, and causal consequences. 2012 APA, all rights reserved).

By using the notions of exact truth and exact falsity, one can give 16 distinct definitions of classical consequence. This paper studies the class of relations that results from these definitions in settings that are paracomplete, paraconsistent or both and that are governed by the Strong Kleene schema. Besides familiar logics such as Strong Kleene logic, the Logic of Paradox and First Degree Entailment, the resulting class of all Strong Kleene generalizations of classical logic also contains a host of (...) unfamiliar logics. We first study the members of our class semantically, after which we present a uniform sequent calculus that is sound and complete with respect to all of them. Two further sequent calculi and \ calculus) will be considered, which serve the same purpose and which are obtained by applying general methods to construct sequent calculi for many-valued logics. Rules and proofs in the SK calculus are much simpler and shorter than those of the \ and the \ calculus, which is one of the reasons to prefer the SK calculus over the latter two. Besides favourably comparing the SK calculus to both the \ and the \ calculus, we also hint at its philosophical significance. (shrink)

It has become something of a consensus among philosophers of history that historians, in contrast to natural scientists, explain in a narrative fashion. Unfortunately, philosophers of history have not said much about how it is that narratives have explanatory power. they do, however, maintain that a narrative’s explanatory power is sui generis and independent of our empathetic or reenactive capacities and of our knowledge of law-like generalizations. In this article I will show that this consensus is mistaken at least (...) in respect to explanatory strategies used to account for rational agency using the “folk-psychological” framework of intentions, beliefs, desires, and the like. philosophers distinguish insufficiently among different aspects and different types of information needed for a historian to persuasively account for an agent’s behavior in particular circumstances. If one keeps these aspects apart it will become apparent exactly how one should understand the epistemic contribution of empathy, generalizations, and narrative for the explanation of action. (shrink)
