Speakers often do not state requests directly but employ innuendos such as Would you like to see my etchings? Though such indirectness seems puzzlingly inefficient, it can be explained by a theory of the strategic speaker, who seeks plausible deniability when he or she is uncertain of whether the hearer is cooperative or antagonistic. A paradigm case is bribing a policeman who may be corrupt or honest: A veiled bribe may be accepted by the former and ignored by the latter. (...) Everyday social interactions can have a similar payoff structure (with emotional rather than legal penalties) whenever a request is implicitly forbidden by the relational model holding between speaker and hearer (e.g., bribing an honest maitre d’, where the reciprocity of the bribe clashes with his authority). Even when a hearer’s willingness is known, indirect speech offers higher-order plausible deniability by preempting certainty, gossip, and common knowledge of the request. In supporting experiments, participants judged the intentions and reactions of characters in scenarios that involved fraught requests varying in politeness and directness. (shrink)

Developmental psychologists have long argued that the capacity to distinguish moral and conventional transgressions develops across cultures and emerges early in life. Children reliably treat moral transgressions as more wrong, more punishable, independent of structures of authority, and universally applicable. However, previous studies have not yet examined the role of these features in mature moral cognition. Using a battery of adult-appropriate cases (including vehicular and sexual assault, reckless behavior, and violations of etiquette and social contracts) we demonstrate that these features (...) also distinguish moral from conventional transgressions in mature moral cognition. Each hypothesized moral transgressions was treated as strongly and clearly immoral. However, our data suggest that although the majority of hypothesized conventional transgressions also form an obvious cluster, social conventions seem to lie along a continuum that stretches from mere matters of personal preference (e.g., getting tattoos or wearing black shoes with a brown belt) to transgressions that are treated as matters for legitimate social sanction (e.g., violating traffic laws or not paying your taxes). We use these findings to discuss issues of universality, domain-specificity, and the importance of using a well-studied set of moral scenarios to examine clinical populations and the underlying neural architecture of moral cognition.

Explanation can be distinguished between linguistic practices and metaphysical relations. At least with respect to metaphysical explanation, some are skeptical that any knowledge gained via explanation qua linguistic practices confers knowledge of explanation qua metaphysical relation. I argue that this skepticism is unfounded. Engaging in the linguistic practice of explanation gives us no reason to skeptical in beliefs about corresponding metaphysical relations like causation or grounding. Moreover, those very linguistic practices can provide resources to justify beliefs in those relations. So, (...) exploring those practices can move us forward in developing an epistemology of grounding and metaphysical explanation. (shrink)

The fact that genes and environment contribute differentially to variation in human behaviors, traits and attitudes is central to the field of behavior genetics. Perceptions about these differential contributions may affect ideas about human agency. We surveyed two independent samples (N = 301 and N = 740) to assess beliefs about free will, determinism, political orientation, and the relative contribution of genes and environment to 21 human traits. We find that lay estimates of genetic influence on these traits cluster into (...) four distinct groups, which differentially predict beliefs about human agency, political orientation, and religiosity. Despite apparent ideological associations with these beliefs, the correspondence between mean lay estimates and published heritability estimates for the surveyed traits is large (r = .77). Belief in genetic determinism emerges as a modest predictor of accuracy in these lay estimates. Additionally, educated mothers with multiple children emerge as particularly accurate in their estimates of the genetic contribution to these traits. (shrink)

Socratic dialogue is widely recognized as an effective teaching tool inside of the classroom. In this paper I will argue that Socratic dialogue is also a highly effective teaching tool outside of the classroom. I will argue that Socratic dialogue is highly effective outside of the classroom because it is a form of learning based assessment. I will also show how instructors can use technology like email to implement Socratic dialogue as a form of teaching and assessment, and thus offer (...) a viable alternative to traditional assessments like exams and papers.

This paper will argue for the teaching of component skills in philosophy. We can distinguish between complex and component skills. Component skills bear a kind of constitutive relation to complex skills. We observe this distinction at use in standard pedagogies related to activities like sports, music performance, and mathematics. The central thesis is that devoting pedagogical resources to the development of component skills, especially at introductory levels, promotes better learning outcomes with respect to complex philosophical skills. Aside from defending this (...) thesis, I will also provide a number of examples of activities that can be used to develop component skills. (shrink)

This paper defends a theory of how it is that games are identical both at a time and over time. I argue that this view is an improvement over the account that Michael Ridge defends in his paper “Individuating Games”. This improvement involves a distinction between two kinds of individuation: constitutive individuation and relational individuation. I argue that this distinction does a better job at solving the various puzzles that are related to the synchronic and diachronic identity of games. I (...) go on to show how this approach can be applied to other social entities. (shrink)

This review examines the final three books in the late Professor Sir Neil MacCormick's series "Law, State and Practical Reason": Rhetoric and the Rule of Law; Institutions of Law: An Essay in Legal Theory; and Practical Reason in Law and Morality . The books represent a monumental accomplishment, providing a restatement of his positions in jurisprudence, while embracing and confronting a remarkable range of traditions and philosophical approaches. Advancing what he terms a "post-positivistic view of law". MacCormick provides "a substantial (...) reworking of ideas [he had] developed over the years". The aim here is to adumbrate and reflect upon some of the themes in the books, with a view to demonstrating the significant and serious contribution which they make to contemporary jurisprudence. Since various themes permeate the books, these are considered broadly in order of the book in which they appear. In particular, such an approach enables us to trace the progression of MacCormick's theory since the publication of his seminal Legal Reasoning and Legal Theory . It is argued that, in many respects, the process can be considered to be one of radical evolution. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Peculiarly Favored Condition of GeneticsJames J. Lee, PhD (bio) and Damien Morris, MSc (bio)Turkheimer and Greer (2024) (henceforth “T&G”) make some fair points about problems in the scientific profession, including the regrettable tendency to promise practical applications of research that then never materialize. However, T&G’s sustained critique of a body of work associated with one particular researcher to make these general points struck us as uncharitable. More pressingly, (...) we feel that the far-reaching conclusions that T&G attempt to draw from the results they review from the Spit for Science (S4S) cohort are unjustified and risk misleading readers that psychiatric and behavioral genetics is in a parlous state.T&G state that S4S “produced a clear answer to the question it was designed to address,” namely, that its results “unambiguously contradict the hypothesis that alcohol-related behaviors have a meaningful genetic basis.” But S4S cannot possibly have provided affirmative evidence for the null hypothesis, because as a single cohort it lacked the statistical power to do so. Elsewhere T&G acknowledge that the sample size of S4S does not suffice for many purposes; they cannot have it both ways. When GCTA has been applied to samples of greater size, it has unambiguously supported the hypothesis that alcohol-related behaviors have a meaningful genetic basis. The UK Biobank yielded estimates exceeding 0.10 for the contribution of single nucleotide polymorphisms (SNPs) with minor allele frequency of greater than 0.05 to the heritability of drinks per week, estimates more than ten times their standard errors (Liu et al., 2019).This heritability contributed by common variants is sometimes called “SNP heritability,” and T&G disparage it for the alleged “disadvantage of being substantially smaller” than “twin and family heritabilities.” Nowhere do T&G consider what the precise numbers actually mean—an approach that can be hazardous to your scientific health, as the late John Loehlin might have said. Let us, then, consider these numbers. Under a model of pure neutrality, SNP and pedigree narrow-sense heritabilities should be fairly close, essentially as a result of factors p(1 − p) canceling in the multiplication of the numbers of SNPs to be found at a given allele frequency by the average heritability contributed per SNP (Hill, 2010). If SNP and pedigree heritabilities are not close, then natural selection must have been acting on [End Page 441] the trait, preventing new mutations of large effect from becoming common and thereby concentrating heritability at allele frequencies lower than those typically studied in genome-wide association studies (GWAS). This deduction has been abundantly confirmed: the tendency of GWAS SNPs to reside in evolutionarily conserved regions (Finucane et al., 2015; Kim et al., 2019), the younger age of GWAS SNPs when compared to control SNPs of comparable frequencies (Gazal et al., 2017), the discovery of several rare variants with larger effects than those observed in typical GWAS (Barton et al., 2021; Chen et al., 2023; Marouli et al., 2017), the directly measured deleterious fitness effects of mutations in evolutionarily constrained genes (Gardner et al., 2022), and the substantial additional genetic variance accumulated when rare variants are included in GCTA-type studies, sometimes enough to close the gap between SNP and pedigree heritabilities (Evans et al., 2018; Jang et al., 2022; Pathan et al., 2024; Wainschtein et al., 2022).The genetic architecture of a typical quantitative trait consists of many sites across the genome that can mutate to affect it, numbering potentially in the millions (Agarwala et al., 2013; Zeng et al., 2021), of which those that are common SNPs have very small effects as a result of selection. This is the message, but T&G seem to find fault with the messenger, painting “tiny” effect sizes as an embarrassment to the field of behavioral genetics as a whole. We prefer to view the finding of high polygenicity as a revelation about nature, rather than as a debating point. What is this finding telling us? If one takes the action of stabilizing selection as the initial assumption (Uyeda et al., 2011), then the extreme polygenicity revealed by GWAS becomes part of the answer to the question regarding how traits can...
