Our concepts of the world come from our common activities in the world. Without coastal fishing, or seafaring, in boats too large for their crews to draw them ashore, there is no place for the concept of a harbour. And without reindeer herding, there will be no concept of JASSA. That is one point. The other is this: without some of the coastal fisherman's skill and local knowledge, you will not be able to recognize a natural harbour when you see (...) one. And without the reindeer herder's skill, you will not be able to recognize a JASSA when you see one. To put it all rather bluntly. Though there is more of both work and experience behind the first part of this article, about the world of coastal fishing, most of my academic friends have found the latter part, about the concept JASSA, the better and more readable. Can it be that the better teacher is the one who has just learnt the lesson himself? (shrink)

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

Machine learning (ML) refers to a class of computer-facilitated methods of statistical modelling. ML modelling techniques are now being widely adopted across the sciences. A number of outspoken representatives from the general public, computer science, various scientific fields, and philosophy of science alike seem to share in the belief that ML will radically disrupt scientific practice or the variety of epistemic outputs science is capable of producing. Such a belief is held, at least in part, because its adherents take ML (...) to exist on novel epistemic footing relative to classical mathematical or statistical modelling approaches utilised in science. Namely, they take modelling with ML to be a “theory-free” enterprise, in the sense of not resting essentially on input from human conceptual grasp on the target phenomenon and domain expertise. I take this view to arise from the further, and more deeply entrenched belief that data is worldly and objective; i.e., data is viewed as recapitulating or representing with perfect fidelity the structure or properties of the systems in nature it is sampled from. Yet most contemporary philosophers of science take on board, in one version or other, the thesis of theory-ladenness or theory-mediation of observation or measurement. From this, it follows that most philosophers of science (and, I will venture, many scientists) hold irreconcilable views on the nature of data, an internal tension which threatens the integrity of their appraisals of ML in science. Taking the thesis of theory-ladenness on board---and its implications for the nature of data seriously---it follows that there is no reason to believe that ML differs fundamentally in its epistemic footing from established mathematical modelling approaches in the sciences. I show that usage and interpretation can differ from “standard practice” in scientific projects which wield the tools of ML without accepting a difference in the epistemic or representational status of such tools.

Pancreatitis is a complex, progressively destructive inflammatory disorder. Alcohol was long thought to be the primary causative agent, but genetic contributions have been of interest since the discovery that rare PRSS1, CFTR and SPINK1 variants were associated with pancreatitis risk. We now report two associations at genome-wide significance identified and replicated at PRSS1-PRSS2 and X-linked CLDN2 through a two-stage genome-wide study. The PRSS1 variant likely affects disease susceptibility by altering expression of the primary trypsinogen gene. The CLDN2 risk allele is (...) associated with atypical localization of claudin-2 in pancreatic acinar cells. The homozygous CLDN2 genotype confers the greatest risk, and its alleles interact with alcohol consumption to amplify risk. These results could partially explain the high frequency of alcohol-related pancreatitis in men. © 2012 Nature America, Inc. All rights reserved. (shrink)

In this paper, we sketch a programme for AI-driven social theory. We begin by defining what we mean by artificial intelligence (AI) in this context. We then lay out our specification for how AI-based models can draw on the growing availability of digital data to help test the validity of different social theories based on their predictive power. In doing so, we use the work of Randall Collins and his state breakdown model to exemplify that, already today, AI-based models can (...) help synthesise knowledge from a variety of sources, reason about the world, and apply what is known across a wide range of problems in a systematic way. However, we also find that AI-driven social theory remains subject to a range of practical, technical, and epistemological limitations. Most critically, existing AI-systems lack three essential capabilities needed to advance social theory in ways that are cumulative, holistic, open-ended, and purposeful. These are (1) semanticisation, i.e., the ability to develop and operationalize verbal concepts to represent machine-manipulable knowledge; (2) transferability, i.e., the ability to transfer what has been learned in one context to another; and (3) generativity, i.e., the ability to independently create and improve on concepts and models. We argue that if the gaps identified here are addressed by further research, there is no reason why, in the future, the most advanced programme in social theory should not be led by AI-driven cumulative advances.

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

For f, g $ \in \omega ^\omega $ let $c_{f,g}^\forall $ be the minimal number of uniform g-splitting trees (or: Slaloms) to cover the uniform f-splitting tree, i.e., for every branch v of the f-tree, one of the g-trees contains v. $c_{f,g}^\exists $ is the dual notion: For every branch v, one of the g-trees guesses v(m) infinitely often.

It appears that consciousness science is progressing soundly, in particular in its search for the neural correlates of consciousness. There are two main approaches to this search, one is content-based (focusing on the contrast between conscious perception of, e.g., faces vs. houses), the other is state-based (focusing on overall conscious states, e.g., the contrast between dreamless sleep vs. the awake state). Methodological and conceptual considerations of a number of concrete studies show that both approaches are problematic: the content-based approach seems (...) to set aside crucial aspects of consciousness; and the state-based approach seems over-inclusive in a way that is hard to rectify without losing sight of the crucial conscious-unconscious contrast. Consequently, the search for the neural correlates of consciousness is in need of new experimental paradigms. (shrink)

Organisations that design and deploy artificial intelligence (AI) systems increasingly commit themselves to high-level, ethical principles. However, there still exists a gap between principles and practices in AI ethics. One major obstacle organisations face when attempting to operationalise AI Ethics is the lack of a well-defined material scope. Put differently, the question to which systems and processes AI ethics principles ought to apply remains unanswered. Of course, there exists no universally accepted definition of AI, and different systems pose different ethical (...) challenges. Nevertheless, pragmatic problem-solving demands that things should be sorted so that their grouping will promote successful actions for some specific end. In this article, we review and compare previous attempts to classify AI systems for the purpose of implementing AI governance in practice. We find that attempts to classify AI systems proposed in previous literature use one of three mental models: _the Switch_, i.e., a binary approach according to which systems either are or are not considered AI systems depending on their characteristics; _the Ladder_, i.e., a risk-based approach that classifies systems according to the ethical risks they pose; and _the Matrix_, i.e., a multi-dimensional classification of systems that take various aspects into account, such as context, input data, and decision-model. Each of these models for classifying AI systems comes with its own set of strengths and weaknesses. By conceptualising different ways of classifying AI systems into simple mental models, we hope to provide organisations that design, deploy, or regulate AI systems with the vocabulary needed to demarcate the material scope of their AI governance frameworks.

Jennifer Lackey has recently presented a new and lucid analysis of the notion ofjustified group belief, i.e. a set of individually necessary and jointly sufficient conditions for a group to justifiedly believe some proposition. In this paper, however, I argue that theanalysansshe proposes is too narrow: one of the conditions she takes to be necessary for justified group belief is not necessary. To substantiate this claim, I present a potential counterexample to Lackey's analysis where a group knows and thus justifiedly (...) believes some proposition but there is no single group member who actually believes that proposition. I close by defending the example against the objection that the group in question does notknowbut is at mostin a positionto know the target proposition. (shrink)

Este texto contrasta o entendimento comum do "perspectivismo de Nietzsche" com o seu uso da palavra "Perspektive" e termos semelhantes. As primeiras seções proporcionam uma breve pesquisa do desenvolvimento dos diversos significados através da carreira de Nietzsche e a influência de Gustav Teichmüller. As seções subsequentes revelam alguns problemas de leituras comuns do perspectivismo, como a teoria do conhecimento de Nietzsche. Discutindo os assuntos de falsificação, objetividade e autorreferência, as seções remanescentes levam à conclusão que o perspectivismo não deve ser (...) entendido como a doutrina epistemológica de Nietzsche, mas como algo que não o deixa criar tal doutrina.This paper contrasts common understandings of "Nietzsche's perspectivism" with his use of the word "Perspektive" and related wordforms.

The next sections unfold some problems of common readings of perspectivism as Nietzsche's theory of knowledge. Discussing the issues of falsification, objectivity and self-reference, the remaining sections lead to the conclusion that perspectivsm should not be understood as Nietzsche's doctrine of epistemology but rather as what keeps him from providing such a doctrine.

In an attempt to demonstrate that local hidden variables are mathematically possible, Pitowsky constructed “spin- functions” and later “Kolmogorovian models”, which employs a nonstandard notion of probability. We describe Pitowsky’s analysis and argue that his notion of hidden variables is in fact just super-determinism. Pitowsky’s first construction uses the Continuum Hypothesis. Farah and Magidor took this as an indication that at some stage physics might give arguments for or against adopting specific new axioms of set theory. We would rather argue (...) that it supports the opposing view, i.e., the widespread intuition “if you need a non-measurable function, it is physically irrelevant”. (shrink)

This could be in the shape of a patient's flawed background beliefs, or biases, which somehow modulate perception or ensure delusional interpretations of experience. There is little agreement about what kind of mechanism is primary in delusion formation, or, indeed, what the particular mechanisms and their neural substrates might be.In the evaluation of top-down and bottom-up mechanisms in delusion formation, a number of conceptual questions should be addressed (Davies and Coltheart 2000). For example, if there is an experiential component, why is a hypothesis with a delusional explanation of the unusual experience seen as relevant? Why do the subjects come to believe it tenaciously? How come some unusual experiences do not develop into delusions?A number of empirical findings also need to be taken into account: for example, the damage to the autonomic system in Capgras delusion (Ellis et al. 1997), the decreased ability for fast error correction in schizophrenia (Frith and Done 1989), modulation of activity in parietal cortex in delusions of alien control and other passivity experiences (Blakemore, Oakley, and Frith 2003), and also in schizophrenia, the increased sensitivity to self-produced stimuli, such as tickling oneself (Blakemore et al. 2000) and the sound of one's own voice (Ford et al. 2001).Theory choice can also be guided by philosophical doctrines about, for example, the nature of belief, the constitutive role of rationality, and intersubjectivity and the nature of judgements about the external world. It is natural, however, to let beliefs about philosophical doctrine be secondary to empirical findings and conceptual issues.The distinction between bottom-up and top-down mechanisms is particularly sharp in John Campbell's (2001) account of delusions and in Tim Bayne and Elisabeth Pacherie's (2004) discussion of Campbell. In this discussion, top-down approaches are associated with the general philosophical doctrine of rationalism, and bottom-up approaches with the philosophical doctrine of empiricism. Campbell's account is top-down because he posits delusional framework beliefs that arise directly as a result of brain damage or malfunction, and that work in some top-down fashion on the interpretation of experience. Bayne [End Page 65] and Pacherie convincingly defend empiricism against Campbell's rationalist account. Among their many other objections, they briefly puzzle about how a delusional framework belief (e.g., that one's spouse is an impostor) in a top-down fashion could cause the damage to the autonomic system seen in the Capgras and Cotard delusions (2004, 1). I think this is a very important objection because skin conductance data are part of the evidence for the bottom-up hypothesis concerning the Capgras delusion. We could add to this, for example, that it is mysterious how belief in a top-down fashion could cause people with schizophrenia to be worse at fast error correction than normal controls, to be better at tickling themselves than normal controls, and to have an increased response to the sound of their own voice.On the other hand, although the skin conductance response (SCR) evidence suggests a bottom-up approach to the Capgras delusion, it does not explain the character of the subjective experience that is hypothesized to give rise to the delusional belief: reduced SCR is not part of the experience itself (thanks to Ian Gold for discussion of this). Something more is required to give a full account of the type of experience that gives rise to the delusion. Further, as they stand, most bottom-up accounts are unable to account for why reality testing fails for beliefs based on these experiences.Neither rationalism nor empiricism on their own seem able to address the conceptual questions while paying...

The topic of this article is religious materiality in a Finnish, Lutheran setting. Reflecting on the altar cross of the Luther Church Helsinki – and more specifically the elevated role the cross played in the re-opening of the church in 2016 – the article supports the argument of recent scholars that Protestant engagement with materiality is not unambiguously negative but rather ambivalent. Using James Bielo’s concept of “legitimizing frames” – i.e. boundaries or landmarks within which Protestants feel safe enough to (...) deal with things and objects – the article suggests a so-called heritagization frame. Objects or things used within such a frame induce in people a sense of past events and experiences – preferably events in which God has made himself known in this world. This, in turn, enables people’s engagement with the objects. (shrink)

We introduce transitive nep and present a simplified version of Shelah’s “preserving a little implies preserving much”: If I is a Suslin ccc ideal (e.g. Lebesgue-null or meager) and P is a transitive nep forcing (e.g. P is Suslin+) and P does not make any I-positive Borel set small, then P does not make any I-positive set small.

The origins of landscape are usually explained in two complementary ways: on the one hand, landscape is initially related to the artistic genre of the same name, i.e. to the painted landscape; on the other hand, and much more recently, it corresponds to landscape experienced by someone, to the mental representa-tion of a piece of nature. This article is based on a third hypothesis: according to him landscape is, at least partly, the result of a series of modern technologies. The (...) modern window, cartography, central perspective and various other human inventions have made it possible to forge a landscape image of the world. Fram-ing a glimpse of nature through the gaze is a cultural fact, mediated by scopic devices, and not a capacity that human beings possess a priori. (shrink)

It has been widely discussed whether the existence of other universes than the known universe is a purely metaphysical consideration. This paper argues to the contrary that the existence of other universes is a meaningful hypothesis, which can be tested based on observable data. The paper applies the perspective of observer bias as an approach for assigning probabilities to the mutually excluding hypotheses of universe vs. multiverse, i.e., whether the known universe is the only universe, or just one universe in (...) an ensemble of universes, a so-called multiverse. The basic idea of the paper relies on the following consideration. In a multiverse, the vast majority of observers would live in universes that are more life friendly. Thus, conditional on there being a multiverse, we should expect to find ourselves in a universe with values of the fundamental parameters that provide particularly fertile grounds for life. In contrast, if there is only a single universe, it may well be the case that there is still a few observers even if the parameters are far from ideal for life, and in that case, those observers will find values of the parameters that are not ideal for intelligent life. It may well be the case that, among all parameter configurations that allow life at least somewhere, those that are not ideal for life far outnumber those that are ideal for life. Based on this elementary consideration, the paper proceeds to propose a quantitative framework to determine probabilities for either hypothesis. In particular, it is described how a future ab initio determination of some of the factors in the Drake equation may be used to infer which one of the two hypotheses is the more likely. A quantitative approach to this end is proposed. Expressing these factors of the Drake equation in the context of the two hypotheses, a general likelihood approach is first described. Then, to support intuition, example computations are provided, illustrating how an actual hypothesis test would work in practice. (shrink)

Francesco Praolini has recently put pressure on the view that justified believability is closed under conjunction introduction. Based on what he calls ‘the hybrid paradox,’ he argues that accepting the principle of conjunction closure for justified believability, quite surprisingly, entails that one must also accept the principle of factivity for justified believability, i.e. that there are no propositions that are justifiably believable and false at the same time. But proponents of conjunction closure can do without factivity, as I argue in (...) this short note. A less demanding principle is available. (shrink)

Wenn eine Person unter einer tödlichen Krankheit leidet und nicht über die Ressourcen für eine medizinische Behandlung verfügt, sind wir normalerweise dazu verpflichtet, ihr die notwendigen Ressourcen bereitzustellen. Wären wir aber in einem biotechnischen Zukunftsszenario, in dem die menschliche Lebensspanne durch Eingriffe in den Alterungsprozess erhöht werden kann, auch dazu verpflichtet, anderen Personen die notwendigen Ressourcen für solche Maßnahmen bereitzustellen? John Harris hat argumentiert, dass wir zu solch einer direkten biotechnischen Lebensverlängerung verpflichtet wären, da ein Leben zu verlängern das Gleiche (...) sei, wie ein Leben zu retten. Im vorliegenden Aufsatz wird gezeigt, dass Harris’ Argument nicht schlüssig ist, da entgegen seiner Prämisse ein begrifflicher Unterschied zwischen der Rettung und der Verlängerung eines Lebens besteht. Auf Grundlage von Harris’ zurückgewiesenem Argument werden dann aber zwei alternative Argumente für eine (prima facie) Pflicht zur direkten Lebensverlängerung konstruiert. Das erste Argument basiert auf der Überlegung, dass durch eine direkte biotechnische Lebensverlängerung trotz des begrifflichen Unterschieds mit einer substanziellen Wahrscheinlichkeit Leben gerettet werden würden. Das zweite Argument besagt, dass trotz deskriptiver Unterschiede eine moralische Äquivalenz zwischen der Rettung und der Verlängerung eines Lebens besteht, sofern durch die bloße Lebensverlängerung das Leben um die gleiche Dauer und Qualität verlängert wird wie durch die Lebensrettung. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------- When a person suffers from a deadly disease and is lacking the resources for a medical treatment, we are normally obliged to provide the necessary resources. But would we also be morally obliged to provide the resources for an extension of someone’s lifespan through anti-aging treatments which might be developed due to biotechnological progress? John Harris has argued that there would be an obligation to such a direct biotechnical life extension because extending a life is the same as saving a life. In the present paper, it will be shown that Harris’ argument is not sound since, contrary to his premise, there is a conceptual difference between extending and saving a life. On the basis of Harris’ rejected argument, though, two alternative arguments for a (prima facie) obligation to direct biotechnical life extension will be developed. The first argument is based on the idea that, despite the conceptual difference, one saves someone’s life with a substantial probability when extending it by direct biotechnical means. In the second argument, it will be argued that there is a moral equivalence between extending and saving someone’s life despite the descriptive differences as far as the additional lifetime has the same duration and quality in both cases.

Resumo: No capítulo 5 do Livro III De anima (430a10-19) Aristóteles distingue entre o νοῦς ποιητικός (nous poietikós), chamado pelos Latinos intellectus agens (intelecto agente), e νοῦς παθητικός (nous pathetikós), chamado pelos Latinos intellectus passivus, ou seja, intellectus possibilis (intelecto possível), termos técnicos e filosóficos mais comuns. O capítulo 5 é de grande importância não só para a filosofia antiga e para os comentadores das obras de Aristóteles, como os comentários de Teofrasto, de Alexander de Afrodisias, de Simplício e Themístius (...) entre outros, mas também para a filosofia do mundo árabe e da Europa latina. Sabe-se que Aristóteles não escreveu um tratado próprio sobre o intelecto, embora possam ser encontradas várias observações acerca do intelecto em suas obras. Os tratados do Intelecto começam com Al-Kindi, Al-Farabi, Avicena e sobretudo Averróis, e se refletem, num sentido crítico e afirmativo, (nos debates) dos tratados latinos, por exemplo, nos tratados de Alberto Magno, de Tomás de Aquino, de Sigério de Brabant entre outros. Este artigo apresenta observações preliminares e preparatórias ao projeto de traduções bilíngue (Latim-Português) dos tratados medievais sobre o intelecto ‘Teorias do Intelecto na Idade Média’ que está em desenvovlimento no Centro Internacional de Estudos Medievais da UFU. Palavras-chaves: Unidade do intelecto; Imaginação; Intencionalidade; Luz intelectual e cognição. Theories of the Intellect in the Latin Middle Ages. De anima III, cap. 5 of Aristotle and his Medieval Tradition Abstract: In the chapter 5 of the III. Book of De anima (430a10-19) Aristotle distinguishes between the νοῦς ποιητικός (nous poietikós) called by the Latins intellectus agens (agent intellect) and the νοῦς παθητικός (nous pathetikós) called by the Latins intellectus passivus, or intellectus possibilis (possible intellect), most common technical and philosophical terms. The chapter 5 is of great importance not only to ancient philosophy and to the commentators of Aristotle’s works such as the commentaries of Theophrastus, Alexander of Aphrodisias, of Simplicius, and Themistius among others, but also to the philosophy of the Arabic World and the Latin Europe. One knows well that Aristotle does not have written a proper treatise on intellect; although there are several observations about the intellect in his works. Separate treatises begin with Al-Kindi, Al-Farabi, Avicenna, and especially Averroes, which Latin treatises as of Albert the Great, Thomas Aquinas, Siger of Brabant among others reflect in a critical as well as an affirmative sense. This article can be read as preliminary and preparatory observations to a bilingual (Latin-Portuguese) translation project of treatises corresponding to ‘Theories of Intellect in the Middle Ages’ which is ongoing at the International Center for Medieval Studies at UFU. Key-words: Unity of the Intellect; Imagination; Intentionality; Intellectual Light; and Cognition. Theorien des Intellekts im Lateinischen Mittelalter. De anima III, 5 des Aristoteles und seine mittelalterliche Tradition Zusammenfassung: Im 5. Kapitel des III. Buchs von De anima (430a10-19) unterscheidet Aristoteles zwischen dem νοῦς ποιητικός (nous poietikós), von den Lateinern intellectus agens (tätiger Intellekt) genannt und dem νοῦς παθητικός (nous pathetikós), von den Lateinern intellectus passivus oder auch intellectus possibilis (möglicher Intellekt) genannt, gemeinhin bekannte technische und philosophische Begriffe. Dieses 5. Kapitel ist von grösster Bedeutung nicht nur für die antike Philosophie und die Kommentatoren der Werke des Aristoteles wie die Kommentare des Theophrastus, des Alexander von Aphrodisias, Simplicius und Themistius unter anderen, sondern auch für die Philosophie der arabischen Welt und des lateinischen Europas. Bekanntlich hat Aristoteles keinen eigenen Traktat über den Intellekt geschrieben, obgleich sich viele Beobachtungen zum Intellekt in seinem Werk antreffen. Selbständige Traktate über den Intellekt beginnen mit Al-Kindi, Al-Farabi, Avicenna und besonders Averroes, die sich in den lateinischen Traktaten, z.B. des Albertus Magnus, Thomas von Aquin, Siger von Brabant und anderen zustimmend wie kritisch widerspiegeln. Dieser Artikel kann als vorläufige und vorbereitende Bemerkungen zu einem zweisprachigen (lateinisch-portugiesischen) Übersetzungsprojekt von Texten gelesen werden, welche „Theorien des Intellekts im Lateinischen Mittelalter“ betreffen. Dieses Projekt ist am Internationalen Zentrum für Mittelalterstudien der UFU in Arbeit genommen worden. Schlüsselwörter: Verstand; Vernunft; Intentionalität; Anschauung und Erkenntnis.

The normative character of meaning creates deep problems for the attempt to give a reductive explanation of the constitution of meaning. I identify and critically examine an increasingly popular Carnap-style position, which I call Internalized Meaning Factualism (versions of which I argue are defended by, e.g., Robert Brandom, Paul Horwich and Huw Price), that promises to solve the problems. According to this position, the problem of meaning can be solved by prohibiting an external perspective on meaning constituting properties. The idea (...) is that if we stick to a perspective on meaning that is internal to meaning discourse, then we can preserve the normativity of meaning and yet locate meaning in the natural world. I develop a generic motivation for this position, but argue that, since this motivation is consistent with the Ramsey–Carnap–Lewis–Jackson reductionist strategy, internalized meaning factualism is unstable. The problems about the normativity of meaning can therefore not be sidestepped in this way. (shrink)

In recruitment, promotion, admission, and other forms of wealth and power apportion, an evaluator typically ranks a set of candidates in terms of their competence. If the evaluator is prejudiced, the resulting ranking will misrepresent the candidates’ actual rankings. This constitutes not only a moral and a practical problem, but also an epistemological one, which begs the question of what we should do—epistemologically—to mitigate it. In a recent paper, Jönsson and Sjödahl in [Episteme 14:499–517, 2017], argue that the epistemic problem (...) can be fruitfully addressed by way of a novel statistical method that changes the products of biased behaviour, i.e. the rankings themselves, rather than the biased persons. Jönsson and Sjödahl’s pioneering proposal is a both a welcome addition to the literature on implicit bias, due the problems with existing implicit bias interventions [see e.g. Lai et al. in J Exp Psychol Gen 143:1765–1785; J Exp Psychol Gen 145:1001–1016, 2014; 2016; Forscher et al. in J Person Soc Psychol 117:522–559, 2019] but also to the literature on prejudice more generally, where many proposed prejudice-reduction strategies enjoy less than adequate empirical support [Paluck and Green in Ann Rev Psychol 60:339–367, 2009]. Their proposal, however, needs supplementation in two ways: the circumstances that must hold in order for it to work needs to be refined, and their claim that it works as intended in these circumstances needs to be validated. We argue that four of Jönsson and Sjödahl’s method’s presumed presuppositions can be weakened, but needs to be supplemented by two additional assumptions, overlooked by Jönsson and Sjödahl. Moreover, we demonstrate that the method does work as intended by way of a statistical simulation. (shrink)
