We offer a case-study in irrationality, showing that even in a high stakes context, intelligent and well trained professionals may adopt dominated practices. In multiple-choice tests one cannot distinguish lucky guesses from answers based on knowledge. Test-makers have dealt with this problem by lowering the incentive to guess, through penalizing errors (called formula scoring), and by eliminating various cues for outperforming random guessing (e.g., a preponderance of correct answers in middle positions), through key balancing. These policies, though widespread and intuitively (...) appealing, are in fact ‘‘irrational’’, and are dominated by alternative solutions. Number-right scoring is superior to formula scoring, and key randomization is superior to key balancing. We suggest that these policies have persisted since all stake-holders – test-makers, test-takers and test-coaches – share the same faulty intuitions. (shrink)

Name der Zeitschrift: Das Mittelalter Jahrgang: 22 Heft: 2 Seiten: 294-313.

Das menschliche Leben vollzieht sich in der Spannung von "Natürlichkeit und Künstlichkeit". Jede Epoche definiert ihre Lebensvollzüge in dieser Spannung neu. Die Gegenwart verzeichnet in ihrem technisch zivilisierten Ambiente neue Schübe von "Künstlichkeit", denen kompensatorisch neue Ideen von "Natürlichkeit" entgegentreten. Der Sport ist davon zentral betroffen. Diese Tagung versucht, von unterschiedlichen philosophischen Fragestellungen her sich dem Problem der Künstlichkeit unseres gegenwärtigen Lebens (und des Sports) zu nähern und das Postulat der "Natürlichkeit" in seiner regulativen Funktion zu begreifen. Die nun in (...) Schriftfassung vorgelegten Vorträge dieser Tagung bieten Diskussionsgrundlagen für notwendige Überlegungen, wenn es darum geht, Konzepte von Bewegung, Spiel und Sport kulturell-historisch zu verstehen und moralisch-ethisch zu kritisieren und zu würdigen.

The doxastic view (DV) of trust maintains that trust essentially involves belief. In a recent paper, Arnon Keren (Citation2020) gestures toward a new objection to the view, labeled Trust’s Meno Problem (TMP), which calls into question the DV’s ability to explain the widely held intuition that trust has distinct and indispensable value. As of yet, there has been no attempt to take up TMP on behalf of DV. This paper aims to fill precisely this lacuna. I do so in three (...) main stages. In §1 I contextualize and elucidate the problem, to which Keren gestures but does not address in detail. In §2 I disambiguate multiple possible interpretations of TMP, seeking to identify the most philosophically challenging. Finally, in §3, I argue that DV can solve even this interpretation. In order to do so, I make use ofthe highly plausible claim we find in the work of Katherine Hawley (Citation2012, 2019): that trust pays a compliment to the trustee. The payoffs of exploring the doxastic view in the context of Trust’s Meno Problem are twofold: we better understand the nature of the problem itself, and we see that the doxastic view can give a satisfying answer.

According to Milner and Goodale’s dual visual systems (DVS) theory, a division obtains between visual consciousness and motor action, in that the visual system producing conscious vision (the ventral stream) is distinct from the one guiding action (the dorsal stream). That there would be this division is often taken (by Andy Clark and others) to undermine the folk view on how consciousness and action relate. However, even if this division obtains, this leaves open the possibility that con- scious ventral information (...) is often transmitted to the uncon- scious dorsal stream and then used to guide action, a possibility seeming to preserve a significant role for consciousness in action. This article assesses this possibility. In course of doing so, we will review those arguments recently having been made against the DVS view on how visual consciousness and action relate (ones due to, e.g., Briscoe and Schwenkler, or Schenk and McIntosh). What we will find is that, if we properly analyze the data upon which these arguments are based, we are still left with the impression that the DVS view is largely correct; i.e., it is only rarely that visual experience guides action.

Despite widespread support for the claim that death can harm the one who dies, debate continues over how to rescue this harm thesis (HT) from Epicurus’s challenge. Disagreements focus on two of the three issues that any defense of HT must resolve: the subject of death’s harm and the timing of its injury. About the nature of death’s harm, however, a consensus has emerged around the view that death harms a subject (when it does) by depriving her of the goods (...) life would’ve afforded had she continued living. This deprivation view of death’s harm (DV) derives some of its credibility from the general deprivation theory of which it is an instance: mortal harm is subject to the same kind of analysis plausibly given of other non-mortal harms. Furthermore, note that the weak formulation of HT—asserting only that death can inflict harm, not that it always or necessarily does—accommodates the intuition that instances of rational suicide and justifiable euthanasia present cases in which death fails to harm. DV is equipped to explain how in these cases the harms involved in continued existence outweigh the goods of which death deprives the subject. I agree that suicide can be rational and that euthanasia can be justifiable. Likewise I accept both HT and DV as far as they go. But they do not go far enough. Specifically, I argue here that death harms even those who die as a result of rational suicide or justifiable euthanasia; that death’s harm is neither undifferentiated nor wholly contingent, but multifaceted and partly necessary; that the necessary part of death’s harm is distinctive, inflicting a peculiar restriction on the autonomy of one who dies; and, regarding the timing and subject issues, that this restriction harm is inflicted on the antemortem subject prior to her death.

Groups do better at reasoning tasks than individuals, and, in some cases, do even better than any of their individual members. Here is an illustration. In the standard version of Wason selection task (Wason, 1966), the most commonly studied problem in the psychology of reasoning, only about 10% of participants give the correct solution, even though it can be arrived at by elementary deductive reasoning.1 Such poor performance begs for an explanation, and a great many have been offered. What makes (...) the selection task relevant here is that the difference between individual and group performance is striking. Moshman & Geil for instance (1998, see also Maciejovsky & Budescu, 2007) had participants try and resolve the task either individually or in groups of five or six participants. While, unsurprisingly, only 9% of the participants working on their own found the correct solution, an astonishing 70% of the groups did. Moreover, when groups were formed with participants who had first tried to solve the task individually, 80% of the groups succeeded, including 30% of the groups in which none of the members had succeeded on his or her own. How are such differences between individual and group performance to be explained? (shrink)

Defenders of doxastic voluntarism accept that we can voluntarily commit ourselves to propositions, including belief-contravening propositions. Thus, defenders of doxastic voluntarism allow that we can choose to believe propositions that are negatively implicated by our evidence. In this paper it is argued that the conjunction of epistemic deontology and doxastic voluntarism as it applies to ordinary cases of belief-contravening propositional commitments is incompatible with evidentialism. In this paper ED and DV will be assumed and this negative result will be used (...) to suggest that voluntary belief-contravening commitments are not themselves beliefs and that these sorts of commitments are not governed by evidentialism. So, the apparent incompatibility of the package views noted above can be resolved without ceding evidentialism with respect to beliefs. (shrink)

Dummett's logic LC quantified, Q-LC, is shown to be characterized by the extended frame Q+, ,D, where Q+ is the set of non-negative rational numbers, is the numerical relation less or equal then and D is the domain function such that for all v, w Q+, Dv and if v w, then D v . D v D w . Moreover, simple completeness proofs of extensions of Q-LC are given.

A statistical method for inference of formal causes was introduced. The procedure, referred to as the method of corresponding regressions, was explained and illustrated using a variety of simulated causal models. The method reflects IV/DV relations among variables traditionally limited to correlational or structural equation analysis. The method was applied to additive, subtractive, multiplicative, recursive and reflected models, as well as models of unrelated and correlated dependent variables. Initial applications to data from physical science, biology, economics, marketing and psychology were (...) developed, with generally supportive results. (shrink)

Most legal theorists, including almost all positivists and many others, take for granted or are implicitly committed to an assumption that is not an official part of positivism. The assumption is that the content of the law is determined by the contents of legally authoritative pronouncements. I call it the Pronouncement View (PV, for short). The kind of determination at issue here is constitutive, not epistemic. That is, PV concerns what makes the content of the law what it is, not (...) how we ascertain the content of the law. PV is more of an organizing principle or core idea, than a precise doctrine. I have introduced PV in an unqualified form, but there are a variety of ways in which its claim could be moderated. For example, a qualified version of PV could hold that the contents of legally authoritative pronouncements play a central or predominant role in determining the content of the law. The debate between positivists and anti-positivists is often framed in a way that takes PV for granted. For example, one typical characterization takes the debate to concern whether laws must pass a moral test in order to be valid. The use of “laws” here betrays an assumption that the starting point is legally authoritative pronouncements. Given this starting point, if morality is relevant it will have to be as a way of screening the content of authoritative pronouncements. I suggest that the issue of whether a PV-based view of law is correct is more fundamental than the issue that divides legal positivists and anti-positivists, at least as the latter issue is commonly understood. For example, one common understanding of the latter issue is that positivists claim, and anti-positivists deny, that the criteria of legal validity – the criteria that determine whether a norm is legally valid – need not include moral facts. As will become clear, however, the picture of law presupposed by this way of framing the debate – according to which candidate norms qualify as legal norms by satisfying criteria of validity – is closely associated with PV and need not be accepted by non-PV-based views of law. PV leads to a characteristic set of concerns and problems, and yields a distinctive way of thinking about how law is supposed to operate. In this paper, I will offer an alternative to PV, which I call the Dependence View (DV, for short). I begin to develop the picture of law that it yields. The discussion throughout is exploratory and tentative. The goal is to sketch the alternative picture and identify problems and possible ways of developing it, not to refute the picture associated with PV. (shrink)

BackgroundConventionally, transcranial direct current stimulation (tDCS) aims to focalize the current reaching the target region-of-interest (ROI). The focality can be quantified by the dose-target-determination-index (DTDI). Despite having a uniform tDCS setup, some individuals receive focal stimulation (high DTDI) while others show reduced focality (“non-focal”). The volume of cerebrospinal fluid (CSF), gray matter (GM), and white matter (WM) underlying each ROI govern the tDCS current distribution inside the brain, thereby regulating focality.AimTo determine the regional volume parameters that differentiate the focal and (...) non-focal groups.MethodsT1-weighted images of the brain from 300 age-sex matched adults were divided into three equal groups- (a) Young (20 ≤ × < 40 years), (b) Middle (40 ≤ × < 60 years), and (c) Older (60 ≤ × < 80 years). For each group, inter and intra-hemispheric montages with electrodes at (1) F3 and right supraorbital region (F3-RSO), and (2) CP5 and Cz (CP5-Cz) were simulated, targeting the left- Dorsolateral Prefrontal Cortex (DLPFC) and -Inferior Parietal Lobule (IPL), respectively. Both montages were simulated for two current doses (1 and 2 mA). For each individual head simulated for a tDCS configuration (montage and dose), the current density at each region-of-interest (ROI) and their DTDI were calculated. The individuals were categorized into two groups- (1) Focal (DTDI ≥ 0.75), and (2) Non-focal (DTDI < 0.75). The regional volume of CSF, GM, and WM of all the ROIs was determined. For each tDCS configuration and ROI, three 3-way analysis of variance was performed considering- (i) GM, (ii) WM, and (iii) CSF as the dependent variable (DV). The age group, sex, and focality group were the between-subject factors. For a given ROI, if any of the 3 DV’s showed a significant main effect or interaction involving the focality group, then that ROI was classified as a “focal ROI.”ResultsRegional CSF was the principal determinant of focality. For interhemispheric F3-RSO montage, interaction effect (p < 0.05) of age and focality was observed at Left Caudate Nucleus, with the focal group exhibiting higher CSF volume. The CSF volume of focal ROI correlated positively (r ∼ 0.16, p < 0.05) with the current density at the target ROI (DLPFC). For intrahemispheric CP5-Cz montage, a significant (p < 0.05) main effect was observed at the left pre- and post-central gyrus, with the focal group showing lower CSF volume. The CSF volume correlated negatively (r ∼ –0.16, p < 0.05) with current density at left IPL. The results were consistent for both current doses.ConclusionThe CSF channels the flow of tDCS current between electrodes with focal ROIs acting like reservoirs of current. The position of focal ROI in the channel determines the stimulation intensity at the target ROI. For focal stimulation in interhemispheric F3-RSO, the proximity of focal ROI reserves the current density at the target ROI (DLPFC). In contrast, for intrahemispheric montage (CP5-Cz), the far-end location of focal ROI reduces the current density at the target (IPL). (shrink)

Artikkelen undersøker hvordan NIPT ble vedtatt implementert i det norske fosterdiagnostiske systemet gjennom en fagligpolitisk prosess mellom 2012 og 2017. Prosessen innebar at Nasjonalt kunnskapssenter for helsetjenesten, Helsedirektoratet, Bioteknologirådet og Helse- og Omsorgsdepartementet ga sine vurderinger av testen og sine råd omkring en eventuell innføring. Artikkelen viser at det i denne prosessen foregikk en forsiktig tilnærming eller sammensmelting mellom de tradisjonelt helt ulike måtene å forstå og å ramme inn fosterdiagnostikk på i Norge, dvs. i en ‘autonomi/ behandlingsramme’ og en (...) ‘sorteringsramme’. Artikkelen argumenterer videre for at denne tilnærmingen eller konvergensen var mulig fordi prosessen ble holdt innenfor de fagligpolitiske byråkratiene, og de ulike etatene var innstilt på å ‘samarbeide’ om å inkludere både kunnskap og verdier fra begge rammene i sine tilrådninger. Politikk for fosterdiagnostikk er imidlertid et svært politisk betent område i Norge, og denne konvergensen var et skjørt byggverk. Den sprakk da også opp i løpet av tre uker i mai 2020, da Fremskrittspartiet plutselig inngikk et ‘bioteknologiforlik’ med Arbeiderpartiet og SV etter at de hadde gått ut av Solbergregjeringen. Dermed endte spørsmålet om implementeringen av NIPT i Stortinget, hvor konvergensen i den fagpolitiske prosessen ble erstattet av de tradisjonelle frontene, og de gamle innrammingene igjen ble ‘satt i arbeid’. Artikkelen diskuterer avslutningsvis kort de bortimot uløselige dilemmaene disse innrammingene både representerer og produserer. Nøkkelord: NIPT, fosterdiagnostikk, humanmedisinsk bioteknologi, regulering English Title: Fetal diagnostics between medicine and ethics: Implementation of Prenatal Invasive Testing in a turbulent policy area: The article examines how the decision to implement Prenatal Invasive Testing in the Norwegian Fetal Diagnostic System was reached through a professional policy process between 2012 and 2017. The process involved the Norwegian Research Centre for Health Services, the Norwegian Directorate of Health, the Norwegian Biotechnology Advisory Board and the Ministry of Health and Care Services, which provided their individual assessments and advice regarding the potential implementation of the test. The article finds that a careful convergence took place between traditionally opposing ways to understand and frame fetal diagnostics in Norway – either as a ‘treatment frame’ or a ‘sorting frame’. The article further argues that this convergence was possible because the process was kept within these bureaucracies, and that the different agencies were willing to collaborate to include knowledge and values from both frames in their recommendations. However, policy for fetal diagnostics is a very turbulent political area in Norway, and this convergence was a fragile construction. During three weeks in May 2020, the convergence collapsed when the Norwegian Progress Party suddenly entered a “biotechnology settlement” with the Labour Party and the Socialist Left Party after exiting the conservative Government coalition. Hence, the question of implementing NIPT ended up in the Norwegian Parliament, where the convergence from the professional policy process was replaced by the traditional fronts, and the old framings were again set in motion. Lastly, the article briefly discusses the almost unsolvable dilemmas these framings both produce and represent. Keywords: NIPT, non-invasive prenatal testing, fetal diagnostics, medical biotechnology, regulation. (shrink)
