This poster presents results from applying agent-based modeling to an exploration of risk attitudes and rational decision making in the context of group interaction. We are also interested in the place of agent-based modeling and computational philosophy within the computational humanities. Computational philosophy has not typically been included in Digital Humanities; computational work has been done using philosophy texts as a source for analysis (Kinney 2022; Malaterre et al. 2021; Fletcher et al. 2021; Zahorec et al. 2022), but there are (...) few examples of philosophical arguments being made based on computation (Zahorec et al. 2022). Modeling is largely accepted as a computational humanist method (McCarty 2004; So 2022), but typically models are based on data rather than designed simulations as a method analogous to a thought experiment (Mayo-Wilson / Zollman 2021). Agent-based modeling is not as common in computational humanities, but we are interested in its potential; for instance, see work modeling correspondence networks to better understand lost information and biases in correspondence data sets (Buarque / Vogl 2023), or work simulating past human societies (Romanowska et al. 2021). Our project explores Lara Buchak’s theory of risk-weighted rational decision making by extending it to the context of group populations and interactions. Buchak has proposed risk-weighted expected utility maximization, which incorporates individual risk attitudes into the standard expected utility (EU) calculation based on utility and probability of outcomes (Buchak 2017). This theory provides an explanation for differences of behavior seen in human populations, while still allowing those different choices to be rational. Buchak’s theory has previously only been applied to individual decision making; our work uses agent-based modeling to develop and analyze simulations which incorporate a variety of risk attitudes (risk avoidance and risk seeking) into game theoretic interactions. This project is a collaboration between a philosopher and a research software engineer; we have worked together to develop simulations that implement agents with risk attitudes making risky choices. This presentation focuses on results from an implementation of a hawk/dove game with multiple risk attitudes and risk attitude adjustment. In the hawk/dove game cooperation, or playing dove, is better for the population, but acting aggressively, or playing hawk, is better for an individual if they are in a neighborhood of doves. To set up the game, we place agents on a grid and have them play against each of their neighbors, and accumulate payoffs based on the success of their plays. We define risk attitudes 0 through 9, where that number corresponds to the minimum number of neighbors playing dove for an agent to play hawk. An agent with risk attitude 0 is most risk seeking and always plays hawk; an agent with risk attitude 1 will play hawk if at least one neighbor plays dove; an agent with risk attitude 9 always takes the safe choice and plays dove; an agent with risk attitude 4 or 5 is risk neutral (breaking ties in different ways), which corresponds to expected utility. In this simulation we randomly set agent initial risk attitudes, and then every ten rounds agents compare their payoffs with their neighbors and adopt the most successful risk attitude in their neighborhood. The simulation is coded to stop once risk attitude adjustments stabilize. We define 13 different population states based on primary and second majority of risk averse, risk inclined, or risk moderate, and analysis of over 1 million runs indicate that while it’s more likely to stabilize with the population having become majority risk inclined, that is not the only outcome; we also see cases where the population stabilizes as risk neutral, risk avoidant, and many cases with no clear majority. This diversity of stable populations provides support for the argument that no one risk attitude is uniquely rational, but rather that risk attitudes are conventional. This matches what we observe in the real world: that different populations have different risk attitudes. Our simulations include numerous parameters to vary grid size; adjustment frequency, strategy, and wealth comparison; neighborhood sizes for observing previous choice, playing against, and comparing payoffs for adjusting risk attitudes; and different distributions for initializing risk attitudes. Analysis of parameters and adjusted risk attitudes shows that the strongest correlations are the initial distribution of risk attitudes, which tend to be preserved. * * * This poster was accepted and presented at the DH2024 conference in Washington, D.C.

Thomas Reid claims to share Locke's view that consciousness is a kind of inner sense. This is puzzling, given the role the inner-sense theory plays in indirect realism and in the theory of ideas generally. I argue that Reid does not in fact hold an inner-sense theory of consciousness and that his view differs importantly from contemporary higher-order theories of consciousness. For Reid, consciousness is a first-order representational process in which a mental state with a particular content suggests the application (...) of recognitional concepts in forming beliefs or judgements to the effect that one is currently undergoing a state with that content. I take up the question of whether Reid's theory leads to a regress, and I argue that while the regress cannot be eliminated, it is mitigated by the non-hierarchical nature of Reid's theory of mind.

Some writers claim that ethicists involved in assessing future technologies like nanotechnology and human enhancement devote too much time to debating issues that may or may not arise, at the expense of addressing more urgent, current issues. This practice has been claimed to squander the scarce and valuable resource of ethical concern. I assess this view, and consider some alternatives to ‘speculative ethics’ that have been put forward. I argue that attempting to restrict ethical debate so as to avoid considering (...) unacceptably speculative scenarios would not only leave scientific progress devoid of ethical guidance, but would also rule out some of our most important ethical projects. I conclude that the issue of speculation is a red herring: what is most important is not that ethicists concentrate on current issues or those that are most likely to arise; but that ethicists, scientists, and others focus on maximising what is most valuable.

Thomas Reid’s epistemological ambitions are decisively at the center of his work. However, if we take such ambitions to be the whole story, we are apt to overlook the theory of mind that Reid develops and deploys against the theory of ideas. Reid’s philosophy of mind is sophisticated and strikingly contemporary, and has, until recently, been lost in the shadow of his other philosophical accomplishments. Here I survey some aspects of Reid’s theory of mind that I find most interesting. I (...) examine whether Reid is a mysterian about the mind, whether Reid has a direct realist theory of perception, and whether Reid has a higher-order, or “inner-sense,” view of consciousness. Along the way I will mention portions of the secondary literature that examine these aspects and point out whether and to what degree I part ways with the interpretations present in the literature.

Vocabulary size has been suggested as a useful measure of “verbal abilities” that correlates with speech recognition scores. Knowing more words is linked to better speech recognition. How vocabulary knowledge translates to general speech recognition mechanisms, how these mechanisms relate to offline speech recognition scores, and how they may be modulated by acoustical distortion or age, is less clear. Age-related differences in linguistic measures may predict age-related differences in speech recognition in noise performance. We hypothesized that speech recognition performance can (...) be predicted by the efficiency of lexical access, which refers to the speed with which a given word can be searched and accessed relative to the size of the mental lexicon. We tested speech recognition in a clinical German sentence-in-noise test at two signal-to-noise ratios (SNRs), in 22 younger (18–35 years) and 22 older (60–78 years) listeners with normal hearing. We also assessed receptive vocabulary, lexical access time, verbal working memory, and hearing thresholds as measures of individual differences. Age group, SNR level, vocabulary size, and lexical access time were significant predictors of individual speech recognition scores, but working memory and hearing threshold were not. Interestingly, longer accessing times were correlated with better speech recognition scores. Hierarchical regression models for each subset of age group and SNR showed very similar patterns: the combination of vocabulary size and lexical access time contributed most to speech recognition performance; only for the younger group at the better SNR (yielding about 85% correct speech recognition) did vocabulary size alone predict performance. Our data suggest that successful speech recognition in noise is mainly modulated by the efficiency of lexical access. This suggests that older adults’ poorer performance in the speech recognition task may have arisen from reduced efficiency in lexical access; with an average vocabulary size similar to that of younger adults, they were still slower in lexical access.

Background: Nonhuman animals are regularly enhanced genomically with CRISPR and other gene editing tools as scientists aim at better models for biomedical research, more tractable agricultural animals, or animals that are otherwise well suited to a defined purpose. This study investigated how genome editors and policymakers perceived ethical or policy benefits and drawbacks for animal enhancement and how perceived benefits and drawbacks are alike, or differ from, those for human genome editing. Methods: We identified scientists through relevant literature searches as (...) well as conference presentations. Policymakers were identified through rosters of genome editing oversight groups (e.g., International Commission on the Clinical Use of Human Germline Genome Editing, World Health Organization) or efforts aimed at influencing policy (e.g., deliberative democracy groups). Interviews covered participants’ views on ethical differences between interventions affecting somatic or germline cells and distinctions between using gene editing for disease treatment, prevention, and enhancement purposes. Results: Of the 92 participants interviewed, 81 were genome editing scientists, and 33 were policymakers, with 22 interviewees being both scientists and policymakers. Multiple areas were identified in which the ethical implications of genomic enhancements for nonhuman animals differ from those for human animals including with respect to experiential welfare; germline edits; environmental sustainability; and justice. Conclusions: Overall, respondents viewed that animal enhancement is unburdened by the ethical complexities of human enhancement. These views may be related to participant perceptions of animals’ lesser moral status and because germline editing in animals is common practice. (shrink)

There is an apparent epidemic of mental illness. At the end of 2011, untreated mental disorders accounted for 13% of the total global burden of disease, and for 25.3% and 33.5% of all years lived with a disability in low-and middle-income countries, respectively. Depression affects 350 million people globally and is the leading cause of disability. One in five U.S. adults takes psychiatric medication. One study found that by age 32, 50% of people surveyed qualified for an anxiety disorder, more (...) than 40% for a mood disorder, and more than 30% for substance dependence.

The climate crisis is beset by depoliticization. Couched as an issue that experts must solve through technological or technocratic knowledge, discussion about how to address environmental degradation is not amenable to democratic action or dissensus. This paper argues that approaching climate change through a human rights framework risks reinscribing such depoliticization and that this is politically hazardous. Human rights discourse can impede the demos’ exercise of power, obscure exercises of hegemony, and, via a fixed notion of progress, discourage normative contestation. (...) This discourse’s depoliticizing potential is further attested to by the debate over human rights’ relationship to the depoliticizing ideology of neoliberalism. Moreover, beyond the language of human rights, the larger legal phenomena of judicialization and juridification may further contribute to depoliticization. Depoliticization is risky because it can provoke politicizing backlashes likely to issue, in the case of climate change, in antidemocratically nationalistic and authoritarian responses to the environmental emergency.

Based on fieldwork in Newmarket, England, and Kentucky, this paper examines the acts of looking that take place at international thoroughbred horse auctions. Racehorse caretakers employ bloodstock agents to select the yearling thoroughbred who will make the best racehorse as a 2-year-old and, hopefully, successful stallion or broodmare after retiring from the track as a 4- or 5-year old. The paper assesses the criteria used to assess yearlings: pedigree, conformation, and "that something extra."The paper concludes that the ambiguous status of (...) the bloodstock agent derives from the liminal task the agent performs, communicating with a young, nonhuman animal to discover the animal's essential properties. Selecting yearlings depends upon a process of divination that mitigates against the characterization of western thought as "rational" and opposed to decision-making processes conventionally thought of as "non-normal" or irrational.

The terminology of “lives not worth living,” “worthwhile lives,” and “unworthwhile lives,” used by John Harris and many others, has become an accepted linguistic convention in bioethical discussions. These terms are used to distinguish lives of overwhelming negative experience from lives that are or are expected to be of overall positive value. As such, this terminology seems helpful in discussions around resource allocation, end-of-life decision making and questions of when it might be acceptable (and unacceptable) to reproduce. This paper argues (...) that there is, however, a problematic ambiguity inherent in these general terms that is particularly evident when it comes to discussing reproductive choices. It is suggested that in this context, this ambiguity can conceal authoritarian eugenic motivations that are difficult to justify and that many using these terms would not adhere to. As a result, it is argued that we should replace these terms with the terms “intrinsically valuable” and “intrinsically harmful.” This would make it more explicit what exactly is meant and would allow these matters to be debated with greater clarity.

I develop and defend a novel account of the private law of remedies according to which it is best understood as facilitating deliberations between the parties about the just outcome of their dispute rather than correcting injustice or righting wrongs. According to my democratic conception, the parties are the ones who ideally ought to resolve moral uncertainty about justice between them by deliberating together in good faith about what justice requires. The law of remedies should therefore often refrain from offering (...) a final judgment about what justice between the parties requires, instead setting and implementing fair default rules and principles in the shadow of which the parties will ideally articulate for themselves a joint vision of justice for their relationship.

ABSTRACT: Recently the discussion surrounding the conceivability thesis has been less about the link between conceivability and possibility per se and more about the requirements of a successful physicalist program. But before entering this debate it is necessary to consider whether conceivability provides us with even prima facie justification for our modal beliefs. I argue that two methods of conceiving—imagining that p and telling a story about p—can provide us with such justification, but only if certain requirements are met. To (...) make these arguments, I consider those of Paul Tidman, whose position I use as a foil.RÉSUMÉ: Dernièrement, le débat sur la thèse de la concevabilité a peu porté sur le lien entre la concevabilité et la possibilité per se et s’est plutôt intéressé aux conditions requises pour la réalisation du programme physicaliste. Toutefois, avant d’entrer dans ce débat, il est nécessaire de se demander si la concevabilité offre une justification même élémentaire des croyances modales. Je soutiens que deux méthodesde concevoir — imaginer que p et raconter une histoire à propos de p — sont susceptibles de nous fournir cette justification, mais seulement dans la limite de certaines conditions. À l’appui de mon propos, j’envisage la position de Paul Tidman, qui me sert de repoussoir. (shrink)

There is a large literature on technology adoption and environmental management in agriculture. Included in this literature are debates about the role world view or attitudinal variables play in adoption decisions, and whether smaller farms or larger farms exhibit superior environmental performance or differ in commitment to environmental values. In this paper we attempt to extend the literature in this area by proposing and measuring discrete environmental management approaches among sixty-six farmers in Northern New York. Using key informants interviews, purposeful (...) sampling of farmers and a mail survey we find two environmental management types: (1) the larger-scale conservation farmer; and (2) the alternative/ecological farmer.

In Christian books today readers can find dozens of spiritual practices. One resource of the Protestant tradition, however, that has largely been forgotten is the Puritan practice of conference. This article describes how for the English Puritans conference exemplified the importance of communal spiritual life, then considers applications for the contemporary church. Conference refers to intentional conversation among believers about spiritual matters. Conference particularly expresses the value of Christian community and the need for the body of Christ to function together (...) on the journey of faith. Understanding this practice not only illuminates the past but also offers valuable insights for the church today. (shrink)

Non-Western Christian missionaries from a variety of backgrounds represent Europe as being in decline in terms of its religiosity and morals. Such evaluations are set against a backdrop of Christian demographic shift from the global North to the global South and secularization theory. The shift in demographics is, however, unfinished, as is the inversion of relations implied by the vocal, critical presence of Southern Christians in Europe. There is great religious variety within Europe, the West and the global South. Hence (...) scholars are developing fresh theoretical lenses to take better account of contexts and connections in analyses, and further research into the relationship between rhetoric and reality is called for.

This chapter examines the consequences of Nietzsche's campaign against morality for the pursuit of knowledge in philosophy, and specifically, on values and methods of the German Enlightenment. In Dawn, Nietzsche explores how an experimental approach to knowing and to knowledge involves us in adopting different ways of being toward things in the world, as well as toward ourselves and our experiences, and in using associated diverse methods of inquiry. Nietzsche's free‐spirit writings, including Dawn, are works of a particular kind of (...) enlightenment project that works against all expressions of fanaticism, especially religious and moral, and in an effort to temper emotional and mental excess. Nietzsche's primary commitment in Dawn is to experimentation in which the love of, or passion for, knowledge gives humanity back its right to engage in self‐experimentation. (shrink)

Who should define what constitutes ethical and lawful medical practice? Judges? Doctors? Scientists? Or someone else entirely? This volume analyses how effectively criminal law operates as a forum for resolving ethical conflict in the delivery of health care. It addresses key questions such as: how does criminal law regulate controversial bioethical areas? What effect, positive or negative, does the use of criminal law have when regulating bioethical conflict? And can the law accommodate moral controversy? By exploring criminal law in theory (...) and in practice and examining the broad field of bioethics as opposed to the narrower terrain of medical ethics, it offers balanced arguments that will help readers form reasoned views on the ethical legitimacy of the invocation and use of criminal law to regulate medical and scientific practice and bioethical issues.

This essay considers Simone Weil's experiences in factories and her social–political reflections on work, time and energy, in conjunction with arguments from theorists Melissa Gregg, Theodor Adorno and Sara Ahmed, to raise questions about supposedly humane interventions, including the cultivation of resilience, in the contemporary workplace. The transition from time‐sense in factory work at the turn of the century is examined, along with the growth of corporate time management ideologies and practices in the mid–late 20th century, and finally, the associated (...) forms of disciplining resilience/elasticity in the worker that bring together certain notions of time, space and psychological investments.

Psychiatry uncomfortably spans biological, psychological, and social perspectives on mental illness. As a branch of medicine, psychiatry is under pressure to conform to a biomedical model, according to which diseases are characterized primarily in biological terms. But psychiatry also draws on the psychotherapeutic tradition, which explains mental distress in terms of life experience and social influences.These approaches ought to complement each other, but historically this has not happened. With no theory creating global, systematic links between the two approaches, psychiatry is (...) divided... (shrink)

Michael Dummett argued that, whilst we can imagine circumstances under which agents may rationally believe themselves capable of affecting the past, the attitude of such agents is bound to seem ‘paradoxical and unnatural to us’. Therefore, only agents very unlike us could intentionally affect the past. I argue that this is not the case. I outline circumstances in which the attitude of such agents is prudent, even by our own standards. Worlds in which backwards causation occurs could, then, contain agents (...) very much like us.

IntroductionThe Managing Cancer and Living Meaningfully therapy for patients with advanced cancer was tested against a supportive psycho-oncological counseling intervention in a randomized controlled trial. We investigated whether CALM was delivered as intended ; whether CALM therapists with less experience in psycho-oncological care show higher adherence scores; and whether potential overlapping treatment elements between CALM and SPI can be identified.MethodsTwo trained and blinded raters assessed on 19 items four subscales of the Treatment Integrity Scale covering treatment domains of CALM. A (...) random sample of 150 audio recordings were rated on a three-point Likert scale with 1 = “adherent to some extent,” 2 = “adherent to a sufficient extent,” 3 = “very adherent.”ResultsAll 19 treatment elements were applied, but in various frequencies. CALM therapists most frequently explored symptoms and/or relationship to health care providers and allowed expression of sadness and anxiety about the progression of disease. The exploration of CALM treatment element SC_1 was most frequently implemented in a satisfactory or excellent manner, whereas the treatment element SMP_4: Therapist promotes acknowledgment that some life goals may no longer be achievable was not implemented in a satisfactory manner. In terms of treatment differentiation, no treatment elements could be identified which were applied significantly more often by CALM therapists than by SPI therapists.ConclusionResults verify the application of CALM treatment domains. However, CALM therapists’ adherence scores indicated manual deviations. Furthermore, raters were not able to significantly distinguish CALM from SPI, implying that overlapping treatment elements were delivered to patients. (shrink)

Multilevel explanations abound in psychiatry. However, formulating useful such explanations is difficult or (some argue) impossible. I point to several ways in which Lane et al. successfully use multilevel explanations to advance understanding of psychotherapeutic effectiveness. I argue that the usefulness of an explanation depends largely on one's purpose, and conclude that this point has been inadequately recognised in psychiatry.

This investigation addresses the hypothesis that negative affect is associated with decreased ability to shift attention to a new focus. Thirty-nine participants completed a covert attentional orienting task and then viewed a distressing film clip. Mood was measured by self-report at the beginning and end of the session. Correlations between attentional orienting performance and self-reported mood indicated that participants with greater response time costs on invalidly cued trials reported more negative affect in response to the film. These results support the (...) hypothesis that negative affect is associated with a slowness to disengage attention. (shrink)

We provide a study of Russell’s argument (in _An Inquiry into Meaning and Truth_) against naive realism in which we distinguish five different forms of the argument. We agree with McLendon’s (1956) criticism, that Russell’s premiss that naive realism _leads to physics_ (our emphasis) is ambiguous as between “leads historically or psychologically” and “leads logically”. However, physics does logically lead to naive realism, in the sense that it presupposes it. In that case it is physics that is false. There is (...) also the possibility that physics and naive realism are compatible, and that possibility obtains if phenomenalism is true. (shrink)
