The Monty Hall Problem (MHP), a process of two-stage decision making, was presented in atypical form via a custom software game. Differing from the normal three-box MHP, the game added one additional box on-screen for each game—culminating on game 23 with 25 on-screen boxes to initially choose from. A total of 108 participants played 23 games (trials) in one of four conditions; (1) “Vanish” condition—all non-winning boxes totally removed from the screen; (2) “Empty” condition—all non-winning boxes remain on-screen, but with (...) an “empty” label on them; (3) “Steroids” condition—all non-winning boxes removed from the screen, with initially chosen box becoming 25% larger; (4) “Steroids2” condition—all non-winning boxes removed from the screen, box not currently chosen becomes 25% larger. Results indicate second-stage on-screen presence of boxes influences switching; with their absence having the opposite effect. Size manipulation appears to elicit demand characteristics resulting in indeterminate influence. (shrink)

Eliminativists sometimes invoke evolutionary debunking arguments against ordinary object beliefs, either to help them establish object skepticism or to soften the appeal of commonsense ontology. I argue that object debunkers face a self-defeat problem: their conclusion undermines the scientific support for one of their premises, because evolutionary biology depends on our object beliefs. Using work on reductionism and multiple realizability from the philosophy of science, I argue that it will not suffice for an eliminativist debunker to simply appeal to some (...) object-free surrogate theory of evolution that results from converting any scientific proposition about some object K into a proposition about simples arranged K-wise. In the process, I examine some hazards peculiar to eliminative reductions of scientific theories, and propose a trilemma for eliminativists who attempt to recoup generality for ontologically sparse reducing theories by appealing to pluralities of simples arranged K-wise. The paper is intended to define and develop the object debunker’s self-defeat problem for further study, and to clarify some of the ways sparse and abundant ontologies interact with scientific theory.

The field of psychology, including cognitive science, is vexed by a crisis of confidence. Although the causes and solutions are varied, we focus here on a common logical problem in inference. The default mode of inference is significance testing, which has a free lunch property where researchers need not make detailed assumptions about the alternative to test the null hypothesis. We present the argument that there is no free lunch; that is, valid testing requires that researchers test the null against (...) a well-specified alternative. We show how this requirement follows from the basic tenets of conventional and Bayesian probability. Moreover, we show in both the conventional and Bayesian framework that not specifying the alternative may lead to rejections of the null hypothesis with scant evidence. We review both frequentist and Bayesian approaches to specifying alternatives, and we show how such specifications improve inference. The field of cognitive science will benefit because consideration of reasonable alternatives will undoubtedly sharpen the intellectual underpinnings of research. (shrink)

Current arguments to increase shareholder power in the large public U.S. corporation need to take account of the well-established historical practice of extensive delegation by shareholders of business decision-making and agenda-control to management and the board, what might be characterized as an absolute delegation rule. This practice sharply limits the power of shareholders to put either business or governance proposals to the shareholders for dispositive resolution. The paper, originally published in 1991 but newly relevant, argues that the rule is based (...) on potential pathologies in shareholder voting rather than the inherent information asymmetry between shareholders and managers. Rational shareholders who know of this asymmetry (and know that others know) would simply vote against most shareholder proposals. But shareholder voting gives rise to potential cycling problems, as shifting shareholder majorities vie for preferred policies, and potential opportunism, as shareholders engage in side deals with management and other shareholders to extract rents in corporate decision-making. Since shareholding patterns are in part a response to control rights, deviations from the absolute delegation rule will predictably lead to greater block ownership, for defensive and offensive reasons. These concerns need to be addressed in arguments for the expansion of shareholder power. (shrink)

Cognitive scientist Donald Hoffman and others have recently advanced an evolutionary debunking argument aimed at our perceptual beliefs in ordinary objects, based on the Interface Theory of Perception. In contrast with most recent criticisms of Interface Theory, which have targeted its characterizations of perception and veridicality, I raise a broad dialectical problem for Hoffman’s debunking argument. I show that the argument is self-defeating, and that responding to this problem by appealing to Universal Darwinism leads to a fatal dilemma for the (...) view. (shrink)

This essay assesses the way that issues relating to freedom of speech and public and private forms of dissent have and have not changed in the People’s Republic of China in recent decades. It looks at the way China’s unusual trajectory suggests that Nathan Sharansky’s famous “town square test,” which is often used to divide countries along a single axis (with “free” nations on one side, “fear” nations on the other) is problematic. The need to take regional variations within China (...) into account is one theme that is stresses. (shrink)

Some metabolic pathways are nearly ubiquitous among organisms: the genes encoding the enzymes for such pathways must therefore be ancient and essential. De novo pyrimidine biosynthesis is an example of one such metabolic pathway. In animals a single protein called CADAbbreviations: CAD, trifunctional protein catalyzing the first three steps of de novo pyrimidine biosynthesis in higher eukaryotes; CPS, carbamyl phosphate synthetase domain; CPSase, carbamyl phosphate synthetase activity; ATC, aspartate transcarbamylase domain; ATCase, aspartate transcarbamylase activity; DHO, dihydroorotase domain; DHOase, dihydroorotase activity; (...) GLN, glutaminase subdomain or subunit of carbamyl phosphate synthetase, GL Nase, glutaminase activity; SYN, synthetase subdomain or subunit of carbamyl phosphate synthetase; SYNase, synthetase activity. carries the first three steps of this pathway. The same three enzymes in prokaryotes are associated with separate proteins. The CAD gene appears to have evolved through a process of gene duplication and DNA rearrangement, leading to an in‐frame gene fusion encoding a chimeric protein. A driving force for the creation of eukaryotic genes encoding multienzymatic proteins such as CAD may be the advantage of coordinate expression of enzymes catalyzing steps in a biosynthetic pathway. The analogous structure in bacteria is the operon. Differences in the translational mechanisms of eukaryotes and prokaryotes may have dictated the different strategies used by organisms to evolve coordinately regulated genes. (shrink)

This article examines the way in which selfhood is constructed in direct-to-consumer advertisements for antidepressant medications. The sample consists of advertisements that appeared in nine popular magazines between 1997 and 2005, television commercials that ran between 2003 and 2005, and online promotional Web sites. The analysis is divided into three sections. First, it is argued that the ads rely on metaphors of communication, information exchange, and plenitude to construct a relationship between biology and selfhood. Second, in offering the choice for (...) antidepressant treatment, the ads grant individuals a new capacity for the exercise of personal agency. Third, the author describes antidepressants as pills that perform a narrative “magic.” In contrast to religious and psychoanalytic narratives that required individuals to incorporate disavowed elements of their selves into an ongoing life narrative, antidepressants are medications that allow individuals to put aside, or jump over, inexplicable and painful moments in their life.

Students in 1989 were at pains to distinguish their actions from those taken by students in the Cultural Revolution. Yet there were important similarities. In the present paper, we identify influence on the Democracy Movement from the Cultural Revolution through (1) the expansion and/or widespread familiarization of repertories of collective action available to Chinese activists; (2) precedents for collective action that may have lowered the barriers to action for some while raising them for others; (3) the participation of people at (...) different stages of their lives in both movements; (4) the transformation of the significance of the ideas of democracy and political authority wrought by the Cultural Revolution for many Chinese; (5) the impact of the Cultural Revolution on Chinese intellectuals; (6) the material consequences of the Cultural Revolution which contributed to China's position in the post-Mao era and the specific issues reform and protest sought to confront; (7) the discourse of corruption which provided the 1989 movement with its strongest links between students and ordinary citizens, and which was accentuated in the Cultural Revolution; (8) the affirmation of the value of ordinary life by which students in the 1980s, encouraged by the `literature of the wounded', rebelled against the Puritanism and denigration of `unauthorized' personal relationships that had been characteristic of the Cultural Revolution; (9) the role of the Cultural Revolution as a cautionary tale, shaping the movement itself, inhibiting some older intellectuals from participating, and determining much of how the government viewed and responded to the Democracy Movement; and (10) the embeddedness in different ways of both Cultural Revolution and 1989 protests in an international context.

Making recognition decisions often requires us to reference the contents of working memory, the information available for ongoing cognitive processing. As such, understanding how recognition decisions are made when based on the contents of working memory is of critical importance. In this work we examine whether recognition decisions based on the contents of visual working memory follow a continuous decision process of graded information about the correct choice or a discrete decision process reflecting only knowing and guessing. We find a (...) clear pattern in favor of a continuous latent strength model of visual working memory–based decision making, supporting the notion that visual recognition decision processes are impacted by the degree of matching between the contents of working memory and the choices given. Relation to relevant findings and the implications for human information processing more generally are discussed. (shrink)

The proposal that the criminal justice system should focus on rehabilitation – rather than retribution, deterrence, or expressive denunciation – is among the least popular ideas in legal philosophy. Foremost among rehabilitation’s alleged weaknesses is that it views criminals as blameless patients to be treated, rather than culpable moral agents to be held accountable. This article offers a new interpretation of the rehabilitative approach that is immune to this objection and that furnishes the moral foundation that this approach has lacked. (...) The view rests on the principle that moral agents owe it to one another to maintain the dependability of their moral capacities. Agents who culpably commit criminal wrongs, however, betray an unacceptable degree of moral unreliability. Punishment, on this theory, consists in the enforcement of the duties that offenders have to reduce their own likelihood of recidivism. (shrink)

The idea that victims of social injustice who commit crimes ought not to be subject to punishment has attracted serious attention in recent legal and political philosophy. R. A. Duff has argued, for example, a states that perpetrates social injustice lacks the standing to punish victims of such injustice who commit crimes. A crucial premiss in his argument concerns the fact that when courts in liberal society mete out legitimate criminal punishments, they are conceived as acting in the name of (...) all citizens—on behalf of the whole political community. Resisting this premiss, Peter Chau has suggested that courts ought to be conceived as acting only in the name of “just citizens”: citizens who cannot be plausibly seen as having contributed to distributive injustice. When conceived in this way, Chau argues, courts can no longer plausibly be regarded as lacking standing to punish. This article uses the debate between Duff and Chau to explain why the question of whether to punish socially deprived offenders can only be answered adequately when connected to broader concerns of democratic theory. Specifically, it argues that Chau’s proposal is not available within the context of the kind of political community upon which (Duff rightly believes) a system of liberal criminal law depends for its justification and maintenance: a community in which citizens see the law as embodying shared norms whose specific demands they disagree about. State officials are morally permitted to see themselves as acting on behalf of a subset of the citizenry, I argue, only in circumstances of democratic crisis : circumstances in which a moral community can no longer be plausibly said to exist.

Most accounts of why physicians have a duty to treat patients during a pandemic look to the special ethical standards of the medical profession. An adequate account must be deeper and broader: it must set the professional duty alongside other individual commitments and broader social values.

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

This article presents empirical evidence to address how some visitors build relationships with a wildland place over time. Insights are drawn from qualitative interviews of recreation visitors to the backcountry at Rocky Mountain National Park in Colorado. The article describes relationship to place as the active construction and accumulation of place meanings. The analysis is organized around three themes that describe how people develop relationships to place: time and experience accrued in place, social and physical interactions in and with the (...) setting, and an active reflective process of regulating sense of identity to affirm commitment to place.

This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect (...) from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.

Should governments pay ransoms to terrorist organisations that unjustly kidnap their citizens? The United Kingdom and the United States refuse to negotiate with terrorist groups that kidnap and threaten to kill their people. In contrast, continental European countries, such as France and Germany, have regularly paid ransoms to rescue hostages. Who is right? This debate has raged in the public domain in recent years, but no sustained attempt has been made to subject the matter to philosophical scrutiny. This article explores (...) this issue, focusing on the case of ransom payments to terrorist organisations. It contends that the state's duty to protect its citizens from murder grounds a defeasible obligation to pay ransoms. It considers the objection that a policy of paying ransoms endangers citizens abroad by increasing the likelihood of future kidnappings, and it explains why this objection is not sufficiently weighty. It then identifies a more powerful objection: namely, that a state's payment of ransoms makes the state complicit in the serious injustices that its ransom payments fund. It concludes that unless states can offset their contributions to such injustices, paying ransoms is wrong. (shrink)

Extract in lieu of Abstract: The purpose of this paper is to propose a hypothesis to illuminate Ortega's critical response to Heidegger's question of being (Seinsfrage). While Ortega integrated the classical requirements for the idea of Being into his idea of human life as radical reality, Heidegger's delineation of human life (Dasein) was only preliminary to the final philosophical task of understanding the question of Being itself (Sein) as the transcendent horizon for human life. For Ortega human life is not (...) merely a preliminary ontology that points to another transcendent reality, but final reality itself. I shall argue here that: (1) Ortega saw Heidegger's Seinsfrage as both empty and dead-ended as a philosophical enterprise; (2) by Heidegger's refusal to understand human life and its circumstances as the final goal of philosophy, he failed to account for the reality of human life in its circumstantial, historical, and methodological dimensions; and (3) Heidegger's philosophical project results in a frozen and metaphysical concept of human nature that transcends the historicality of humanity's actual existence and artificially bifurcates history into opposed metaphysical and empirical dimensions that only Ortega's doctrine of historical reason can synthesize.

Several issues are raised concerning the notion that a single strategy explains Fitts' law and the linear speed/accuracy trade-off. Two additional concerns are discussed: (1) distance is programmed, (2) the fact that movements produced without the aid of vision obey Fitts' law does not mean that sighted movements must be explained without regard to vision.

Why, exactly, should we punish children who commit crimes more leniently than adults who commit the same offenses? Gideon Yaffe thinks it is because they cannot vote, and so the strength of their reasons to obey the law is weaker than if they could. They are thus less culpable when they disobey. This argument invites an obvious objection: why not simply enfranchise children, thereby granting them legal reasons that are the same strength as enfranchised adults, and so permitting similarly severe (...) punishment? Yaffe answers this question by arguing that child enfranchisement would objectionably undermine the values of political equality and self-government. This article explores some serious doubts about these arguments. It closes by questioning Yaffe’s reliance on a retributivist theory of punishment, contending that, once we reject retributivism in favor of more humane and productive alternatives, the thesis that child criminals deserve a break—which Yaffe assumes to be undeniably correct—becomes less plausible.
