The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p-hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view. I argue that questionable and other research practices do not usually inflate relevant Type I error rates. I begin (...) by introducing the concept of Type I error rates and distinguishing between statistical errors and theoretical errors. I then illustrate my argument with respect to model misspecification, multiple testing, selective inference, forking paths, exploratory analyses, p-hacking, optional stopping, double dipping, and HARKing. In each case, I demonstrate that relevant Type I error rates are not usually inflated above their nominal level, and in the rare cases that they are, the inflation is easily identified and resolved. I conclude that the replication crisis may be explained, at least in part, by researchers’ misinterpretation of statistical errors and their underestimation of theoretical errors. (shrink)

Kerr coined the term ‘HARKing’ to refer to the practice of ‘hypothesizing after the results are known’. This questionable research practice has received increased attention in recent years because it is thought to have contributed to low replication rates in science. The present article discusses the concept of HARKing from a philosophical standpoint and then undertakes a critical review of Kerr’s twelve potential costs of HARKing. It is argued that these potential costs are either misconceived, misattributed to HARKing, lacking evidence, (...) or that they do not take into account pre- and post-publication peer review and public availability to research materials and data. It is concluded that it is premature to conclude that HARKing has led to low replication rates. (shrink)

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to 0.025 (...) when testing H1,1 and H1,2, find a significant result for H1,1 (p < 0.025) and not for H1,2 (p > .0.025), and so claim support for H1,1 and not for H1,2. However, these separate individual inferences do not require an alpha adjustment. Only a statistical inference about the union alternative hypothesis “H1,1 or H1,2” requires an alpha adjustment because it is based on “at least one” significant result among the two tests, and so it refers to the familywise error rate. Hence, an inconsistent correction occurs when a researcher corrects their alpha level during multiple testing but does not make an inference about a union alternative hypothesis. In the present article, I discuss this inconsistent correction problem, including its reduction in statistical power for tests of individual hypotheses and its potential causes vis-à-vis error rate confusions and the alpha adjustment ritual. I also provide three illustrations of inconsistent corrections from recent psychology studies. I conclude that inconsistent corrections represent a symptom of statisticism, and I call for a more nuanced inference-based approach to multiple testing corrections. (shrink)

The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two (...) types of Type I error probability: the Neyman–Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman–Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman–Pearson Type I error rate across a long run of exact replications.

In lieu of an abstract, here is a brief excerpt of the content:Epistemic Leaks and Epistemic Meltdowns: A Response to William Morris on Scepticism with Regard to Reason Mikael M. Karlsson I. In an excellent paper which appeared in the April, 1989 issue of this journal,2 William Morris attemptsto demonstrate thatthe arguments which make up Hume's notorious chapter, "Of scepticism with regard to reason, are, in the first place, coherent—both internally and with the overall strategy of the Treatise—and, in (...) the second place, successful. Morris' paper is an exercise in the noble art of what I style constructive exegesis, an enterprise to which many readers of Hume Studies, and myself as much as any, are committed. It is a guiding principle ofthis art that we donotunderstandaphilosophical textuntil we can interpret it in such a way as to render it both coherent and correct. From this point ofview, coherence and correctness are not as independent of one another as they may seem to be to others who are differently committed. Some texts, such as Hume's chapter, "Ofscepticism with regard to reason," are notoriously resistant to constructive exegesis, despite the formidable bag of tricks which scholars and interpreters have developed; so resistant, that in gloomier moments we may be brought to wonder about our interpretative enterprise itself. Constructive exegesis is indeed a strange, and peculiarly optimistic, enterprise. Someday, I imagine, in a leisurely moment, I will think more reflectively about the principles ofour art. But not now.6 As a fellow practitioner of constructive exegesis, I am in full sympathy with what Morris tries to do in his paper; and I think that he does contribute substantially to our understanding of what Hume is up to in the chapter, "Ofscepticism with regard to reason." The third section of Morris' paper is, in my judgement, particularly successful in showing how Hume's chapter fits into the larger framework of the Treatise: Hume is, we see, attacking both what Morris labels "intellectualist rationalism" and its counterpart, which we may call 'unmitigated scepticism', although the chapter's two main arguments go primarily to the former. I also think that Morris gives very helpful, Volume XVI Number 2 121 MIKAEL M. KARLSSON and to my mind accurate, accounts of these two arguments, which I dub, respectively, the epistemic leak argument, and the epistemic meltdown argument. However, I have personally never found either of these arguments remotely convincing; and I still do not, despite Morris' clarification and defense. In what follows, I shall indicate some ofthe reasons for my dissatisfaction.?. Theepistemicleakargumentpurportsto"prove"(in Hume's sense)that reason or demonstration cannot support knowledge. Morris rightlyreminds us that whatHume meansby knowledge is perfect assurance or conviction: Knowledge is, in short, subjective certainty. This has caused confusion, for this is not what we usually mean nowadays by knowledge; nor was it what people, philosophers included, generally meant prior to Descartes. In Hume itis the product ofthe attempttoresolve all epistemic statesintomental eventsorwhat he calls "perceptions." In any case, we must—as Morris rightly explains—be clear that the epistemic leak argument is aimed at showing that demonstration cannot supportperfect conviction. Inoutline, the argumentissimple: Itworks, asMorrismakes clear, by shifting attention away from the subject-matter or "objects" of demonstration, that is, relations of ideas, to the exercise of demonstrative reason by human agents. The necessity of relations of ideas may suggest to us that we can be certain about them. Against this, one may point out that people do err in the conclusions arrived at by demonstration; this presumably shows that our (rational) understandingis fallible. And once we recognize this, our confidence in any conclusion produced by exercising this facultyislessened—thus do we move from knowledge, or subjective certainty, toprobability: belief, or imperfect conviction. Arguments ofthis general type (we can call them, using Descartes' famous figure, Totten-apple arguments ) were around long before Hume, although they were more commonly directed against the senses than against reason. We find them in antiquity—in Plato and Sextus Empiricus, for instance —and in Descartes, in parallel passages in the Discourse on Method, the First Meditation and the Principles of Philosophy, wherein one can discern a version directed precisely against reason and demonstration.12 To find out what, if anything, Hume has...

Scientists often adjust their significance threshold during null hypothesis significance testing in order to take into account multiple testing and multiple comparisons. This alpha adjustment has become particularly relevant in the context of the replication crisis in science. The present article considers the conditions in which this alpha adjustment is appropriate and the conditions in which it is inappropriate. A distinction is drawn between three types of multiple testing: disjunction testing, conjunction testing, and individual testing. It is argued that alpha (...) adjustment is only appropriate in the case of disjunction testing, in which at least one test result must be significant in order to reject the associated joint null hypothesis. Alpha adjustment is inappropriate in the case of conjunction testing, in which all relevant results must be significant in order to reject the joint null hypothesis. Alpha adjustment is also inappropriate in the case of individual testing, in which each individual result must be significant in order to reject each associated individual null hypothesis. The conditions under which each of these three types of multiple testing is warranted are examined. It is concluded that researchers should not automatically assume that alpha adjustment is necessary during multiple testing. Illustrations are provided in relation to joint studywise hypotheses and joint multiway ANOVAwise hypotheses. (shrink)

The metaphysical vision of Advaita Vedānta has been making its way into some corners of Western analytic philosophy, and has especially garnered attention among those philosophers who are seeking to develop metaphysical systems in opposition to both reductionist materialism and dualism. Given Vedānta’s monistic view of consciousness, it might seem natural to put Vedānta in dialogue with the growing position of panpsychism which, although not fully monistic, similarly takes mind to be a fundamental feature of reality. This paper will evaluate (...) to what extent Śaṅkara’s monism can bypass the most pressing issues facing panpsychism, namely combination and individuation problems. As will be seen in this paper, while Advaita Vedānta is able to avoid some of the panpsychist problems, it struggles ultimately to ontologically ground illusion in a coherent manner. As a result, a conclusion of this paper is that although Śaṅkara’s vision offers a promising route for those philosophers who take consciousness to be fundamental – including panpsychists – it cannot be uncritically adopted due to the problem of grounding Illusion.

Several researchers have recently argued that p values lose their meaning in exploratory analyses due to an unknown inflation of the alpha level (e.g., Nosek & Lakens, 2014; Wagenmakers, 2016). For this argument to be tenable, the familywise error rate must be defined in relation to the number of hypotheses that are tested in the same study or article. Under this conceptualization, the familywise error rate is usually unknowable in exploratory analyses because it is usually unclear how many hypotheses have (...) been tested on a spontaneous basis and then omitted from the final research report. In the present article, I argue that it is inappropriate to conceptualize the familywise error rate in relation to the number of hypotheses that are tested. Instead, it is more appropriate to conceptualize familywise error in relation to the number of different tests that are conducted on the same null hypothesis in the same study. Under this conceptualization, alpha level adjustments in exploratory analyses are (a) less necessary and (b) objectively verifiable. As a result, p values do not lose their meaning in exploratory analyses. (shrink)

Fisher criticised the Neyman-Pearson approach to hypothesis testing by arguing that it relies on the assumption of “repeated sampling from the same population.” The present article considers the responses to this criticism provided by Pearson and Neyman. Pearson interpreted alpha levels in relation to imaginary replications of the original test. This interpretation is appropriate when test users are sure that their replications will be equivalent to one another. However, by definition, scientific researchers do not possess sufficient knowledge about the relevant (...) and irrelevant aspects of their tests and populations to be sure that their replications will be equivalent to one another. Pearson also interpreted the alpha level as a personal rule that guides researchers’ behavior during hypothesis testing. However, this interpretation fails to acknowledge that the same researcher may use different alpha levels in different testing situations. Addressing this problem, Neyman proposed that the average alpha level adopted by a particular researcher can be viewed as an indicator of that researcher’s typical Type I error rate. Researchers’ average alpha levels may be informative from a metascientific perspective. However, they are not useful from a scientific perspective. Scientists are more concerned with the error rates of specific tests of specific hypotheses, rather than the error rates of their colleagues. It is concluded that neither Neyman nor Pearson adequately rebutted Fisher’s “repeated sampling” criticism. Fisher’s significance testing approach is briefly considered as an alternative to the Neyman-Pearson approach. (shrink)

Hypothesizing after the results are known, or HARKing, occurs when researchers check their research results and then add or remove hypotheses on the basis of those results without acknowledging this process in their research report (Kerr, 1998). In the present article, I discuss three forms of HARKing: (1) using current results to construct post hoc hypotheses that are then reported as if they were a priori hypotheses; (2) retrieving hypotheses from a post hoc literature search and reporting them as a (...) priori hypotheses; and (3) failing to report a priori hypotheses that are unsupported by the current results. These three types of HARKing are often characterized as being bad for science and a potential cause of the current replication crisis. In the present article, I use insights from the philosophy of science to present a more nuanced view. Specifically, I identify the conditions under which each of these three types of HARKing is most and least likely to be bad for science. I conclude with a brief discussion about the ethics of each type of HARKing. (shrink)

Gelman and Loken (2013, 2014) proposed that when researchers base their statistical analyses on the idiosyncratic characteristics of a specific sample (e.g., a nonlinear transformation of a variable because it is skewed), they open up alternative analysis paths in potential replications of their study that are based on different samples (i.e., no transformation of the variable because it is not skewed). These alternative analysis paths count as additional (multiple) tests and, consequently, they increase the probability of making a Type I (...) error during hypothesis testing. The present article considers this forking paths problem and evaluates four potential solutions that might be used in psychology and other fields: (a) adjusting the prespecified alpha level, (b) preregistration, (c) sensitivity analyses, and (d) abandoning the Neyman-Pearson approach. It is concluded that although preregistration and sensitivity analyses are effective solutions to p-hacking, they are ineffective against result-neutral forking paths, such as those caused by transforming data. Conversely, although adjusting the alpha level cannot address p-hacking, it can be effective for result-neutral forking paths. Finally, abandoning the Neyman-Pearson approach represents a further solution to the forking paths problem. (shrink)

In this essay, I maintain that although atheism, minimally construed, consists simply of the belief that there is no God or gods, atheists must embrace a secular worldview of one kind or another. Since they cannot be without a worldview, atheists must develop an alternative to the religious, especially the theistic, worldviews which they, by implication, reject. Further, I argue that there are, at the very least, two options available to atheists and that these should not be conflated or treated (...) as one and the same. The two options that I explore and distinguish are scientism and secular humanism. I also maintain that the things that might count as good grounds for or against secular or religious worldviews are shaped significantly by whether atheists embrace scientism or secular humanism.

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests. In this article, we challenge this proposition and argue that there (...) are several advantages of exploratory hypothesis tests that can make their results more compelling than those of confirmatory hypothesis tests. We also consider some potential disadvantages of exploratory hypothesis tests and conclude that their advantages can outweigh the disadvantages. We conclude that exploratory hypothesis tests avoid researcher commitment and researcher prophecy biases, reduce the probability of data fraud, are more appropriate in the context of unplanned deviations, facilitate inference to the best explanation, and allow peer reviewers to make additional contributions at the data analysis stage. In contrast, confirmatory hypothesis tests may lead to an inappropriate level of confidence in research conclusions, less appropriate analyses in the context of unplanned deviations, and greater bias and errors in theoretical inferences.

In this paper, we provide a detailed review of previous classifications of 2 × 2 games and suggest a mathematically simple way to classify the symmetric 2 × 2 games based on a decomposition of the payoff matrix into a cooperative and a zero-sum part. We argue that differences in the interaction between the parts is what makes games interesting in different ways. Our claim is supported by evolutionary computer experiments and findings in previous literature. In addition, we provide a (...) method for using a stereographic projection to create a compact 2-d representation of the game space. (shrink)

In this essay I identify and develop an alternative to pluralism which is overlooked in contemporary debate in philosophy of religion and in theology. According to this view, some but not all of the great world religions are equally correct, that is to say, they are just as successful when it comes to tracking the truth and providing a path to salvation. This alternative is not haunted by the same difficulty as pluralism, namely the problem of emptiness. It is therefore (...) more rational at least for many Muslims, but probably also for many Christians and Jews, to embrace it rather than to embrace pluralism. Whether it is also to be preferred over exclusivism and inclusivism is a topic which I will not address in this essay. (shrink)

O artigo analisa a leitura crítica de Hans Kelsen acerca da concepção jurídico-política de Thomas Hobbes, considerando críticas posteriores à própria interpretação de Kelsen. Para tanto, investigou-se primeiramente a posição de Kelsen sobre o jusnaturalismo buscando esclarecer conceitos centrais como os do ser e dever-ser e como o autor os associa a Hobbes. Nesse sentido, observouse a limitação da leitura de Kelsen em relação à filosofia jurídica do autor – uma doutrina jusnaturalista metafísica, tendo na regra de ouro o fundamento (...) natural para o direito positivo. Em contraposição, procurou-se apresentar uma postura crítica, que contesta a posição jusnaturalista atribuída a Hobbes e sustenta a tese de que o autor inglês é um precursor do positivismo jurídico.

Metascientists have studied questionable research practices in science. The present article considers the parallel concept of questionable metascience practices (QMPs). A QMP is a research practice, assumption, or perspective that has been questioned by several commentators as being potentially problematic for metascience and/or the science reform movement. The present article reviews ten QMPs that relate to criticism, replication, bias, generalization, and the characterization of science. Specifically, the following QMPs are considered: (1) rejecting or ignoring self-criticism; (2) a fast ‘n’ bropen (...) scientific criticism style; (3) overplaying the role of replication in science; (4) assuming a replication rate is “too low” without specifying an “acceptable” rate; (5) an unacknowledged metabias towards explaining the replication crisis in terms of researcher bias; (6) assuming that researcher bias can be reduced; (7) devaluing exploratory results as being more “tentative” than confirmatory results; (8) presuming that questionable research practices are problematic research practices; (9) focusing on knowledge accumulation; and (10) focusing on specific scientific methods. It is stressed that only some metascientists engage in some QMPs some of the time, and that these QMPs may not always be problematic. Research is required to estimate the prevalence and impact of QMPs. In the meantime, QMPs should be viewed as invitations to ask questions about how we go about doing better metascience. (shrink)

Popper’s (1983, 2002) philosophy of science has enjoyed something of a renaissance in the wake of the replication crisis, offering a philosophical basis for the ensuing science reform movement. However, adherence to Popper’s approach may also be at least partly responsible for the sense of “crisis” that has developed following multiple unexpected replication failures. In this article, I contrast Popper’s approach with Lakatos’ (1978) approach and a related approach called naïve methodological falsificationism (NMF; Lakatos, 1978). The Popperian approach is powerful (...) because it is based on logical refutation, but its theories are noncausal and, therefore, lacking in scientific value. In contrast, the Lakatosian approach considers causal theories, but it concedes that these theories are not logically refutable. Finally, the NMF approach subjects Lakatosian causal theories to Popperian logical refutations. However, its approach of temporarily accepting a ceteris paribus clause during theory testing may be viewed as scientifically inappropriate, epistemically inconsistent, and “completely redundant” (Lakatos, 1978, p. 40). I conclude that the replication “crisis” makes the most sense in the context of the Popperian and NMF approaches because it is only in these two approaches that replication failures represent logical refutations of theories. In contrast, replication failures are less problematic in the Lakatosian approach because they do not logically refute theories. Indeed, in the Lakatosian approach, replication failures can be legitimately ignored or used to motivate theory development. (shrink)

A presente dissertação tem como tema central a proposta da abordagem hermenêutica da decisão judicial em Hans Kelsen considerando seu relativismo filosófico. No primeiro momento expõe a concepção de decisão judicial no autor e as suas reformulações conceituais no decorrer das suas obras – as passagens do formalismo normativista das primeiras obras até o ceticismo de regras na Teoria geral das normas. Também propõe a dissolução entre as leituras formalistas e realistas através da possibilidade de uma leitura realista moderada. Após (...) expõe a filosofia relativista do autor e seu resultado na exclusão dos elementos da moralidade do conceito de direito. Finalmente deduz regras de interpretação a partir de uma visão abrangente das obras do autor. O objetivo da dissertação, nesse sentido, é analisar a dinâmica da criação normativa pelo judiciário, a discricionariedade daí resultante e a possibilidade de interpretar os vários sentidos das normas sem recorrer a qualquer moralismo para tal.

Habermas frequentemente adota o termo Estado de direito na sua obra Direito e democracia: entre facticidade e validade. O objetivo deste artigo, então, consiste na investigação da possibilidade desse conceito, no seu fundamento e na apresentação dos problemas dele decorrentes, contrapondo-o especificamente a sua antítese, isto é, ao monismo entre Estado e direito de Kelsen. Ocorre que a filosofia habermasiana, conforme entendimento do artigo, implica a adoção de uma teoria dualista entre os conceitos de Estado e de direito. Observa-se, assim, (...) o compromisso do filósofo alemão com a reformulação de uma doutrina jurídica específica e sua radical incompatibilidade com o positivismo kelseniano. (shrink)

Pretendeu-se estudar a aquisição da virtude em Aristóteles a partir da interpretação de M. F. Burnyeat. Para esse, a virtude aristotélica exige dimensões cognitivas e emocionais, sendo que ao aprendiz não basta conhecer os princípios e as regras gerais da ação, mas deve ter internalizado, através do hábito, uma vontade de praticar ações nobres e justas. Compete ao sujeito virtuoso, portanto, ter o conhecimento do que é correto (the that), assim como, subsidiariamente, a justificativa do porquê é apropriada determinada ação (...) (the because). Da análise dessas variáveis, o autor procura esclarecer a figura conflituosa do akratic (incontinente) e do akalastos (perverso) e elucidar a hipótese do desenvolvimento moral. Concomitantemente este artigo pretende introduzir o problema criminológico da ideia de ressocialização ou da pena capital, entendendo ser o argumento aristotélico ainda influente para a filosofia da virtude e jurídica hodierna e necessário quando se discutem novos paradigmas éticos e jurídicos.

O objetivo do artigofoi especular sobre a epistemologia proposta por David Hume (1711-1776), especificamente a perspectiva empirista e cética. Procurou-se, assim, expor os principais conceitos da sua filosofia, especialmente acrítica à concepção de causalidade, o problema da probabilidade e os conceitos de percepções, imagens e ideias. Finalmente buscou-se expor uma interpretação que entende haver um ceticismo mitigado no autor e a superação de uma teoria do conhecimento exclusivamente psicológica.

O presente artigo aborda o problema da soberania para Hans Kelsen. Tem como objetivo analisar a posição do autor sobre o tema (especialmente através do texto Sovereignty), traçando paralelamente algumas considerações. Ocorre que para Kelsen o conceito de soberania mostra-se impreciso a partir da doutrina tradicional. Ainda, mesmo superando essa doutrina e a teoria dualista, também o conteúdo do direito nacional e internacional permanece inalterado. Portanto, prova-se a irrelevância de tal para a teoria jurídica.

O artigo tem como objetivo apresentar o problema da determinação do sentido das normas para o Kelsen considerando a flexibilidade do quadro de interpretações. Expõe, primeiramente, a suposta transição do conceito de interpretação normativa, passando de um formalismo-normativismo restritivo para um realismo jurídico a partir das suas últimas obras; em um segundo momento apresenta o decorrente conflito ainda atual constituído por essas reformulações. Finalmente, defende a hipótese de superação da dicotomia formalismo-normativismo versus realismo jurídico através de uma leitura realista normativista.

O trabalho busca esclarecer dois pontos centrais da Filosofia política de Maquiavel – as figuras da Virtù e da Fortuna. A virtú deve ser vista como uma forma do livre-arbítrio do governante, sendo a principal variável na condução do principado.Destaca-se, também, a utilização da variável nacontestação aos valorestradicionais. Já a Fortuna constitui-se na indeterminabilidade de parte dos resultadosdo governo: ela deve ser dominada, conquistada para o benefício do príncipe.

A separação entre o ser, isto é, o ato, e o dever-ser, ou seja, o sentido de comando, permissão etc.. do ato é parte fundamental para o entendimento da epistemologia proposta por Hans Kelsen. Dessa discriminação entre o ser e o dever-ser há o principal argumento do autor para a separação do direito das ciências causais e, principalmente, a superação da falácia naturalista no âmbito teórico e moral. Nesse sentido, também o artigo se propôs a analisar a refutação de Kelsen (...) a doutrinas morais e jurídicas negadoras de tal distinção e, consequentemente o reflexo de tal posicionamento na perspectiva da responsabilidade.

No final do trabalho apresentou-se seis críticas ao texto estudado – o problema da arrogância e dissimulação filosófica, (...) a adoção tácita de um platonismo e a não originalidade filosófica, o problema da falácia naturalista e do falsificacionismo e, finalmente, a não razoabilidade política das propostas.

O objetivo do trabalho é auxiliar o jurista desocupado responsável pelo ensino da cadeira de filosofia do direito. A situação mais frequente nas faculdades de direito são as aulas de filosofia e de outras cadeiras do eixo fundamental serem tapeadas por qualquer bacharel sem nada melhor para fazer. Ocorre que tais ociosos juristas muitas vezes se veem receosos quando instituídos nos seus cargos, isso porque não possuem qualquer conhecimento na matéria em que lecionam, ao mesmo tempo em que são lançados (...) em sala de aula expostos às dúvidas e críticas dos alunos. Nesse sentido apresento a esses professores, juristas desocupados, uma técnica pedagógica resumida e de fácil compreensão para ministrarem sem maiores sobressaltos a cadeira de filosofia do direito. Seguindo os passos propostos, o jurista desocupado não terá riscos de ser questionado pelos alunos ou pela instituição, mantendo seu complemento de renda garantido. (shrink)

A teoria do Direito internacional de Kelsen é monista, ou seja, o autor reúne a legislação nacional e internacional em um único sistema normativo. Com isso, descarta o dualismo e promove uma tese fundada no princípio lógico da não-contradição, traduzido juridicamente para o princípio da imputação. Por essa afirmação, o Direito internacional, considerando o primado estadual, existe a partir do reconhecimento interno da validade da legislação externa; mais, a recepção dos acordos internacionais na legislação nacional acopla internamente o Direito internacional, (...) com seus tratados bi/multilaterais, pactos, instituições, costumes e tribunais. A teoria de Kelsen torna-se complexa, porém, quando, indagando o inverso dessa premissa, o Direito internacional posto e eficaz, já inserido internamente, não reconhece a validade normativa de eventual interpretação ou norma interna e atua como agente determinante da ordem jurídica nacional. Com isso, o Direito externo torna-se decisivo desse mesmo sistema jurídico interno, não necessariamente por uma ação coercitiva, mas por intermédio do seu reconhecimento da validade da legislação interna. Vimos esse fenômeno materializar-se no caso dos dois presidentes simultâneos da Venezuela: tanto o presidente Nicolás Maduro, quando o presidente Juan Guaidó, foram formalmente designados, por países e instituições distintas, como governantes válidos. Sendo assim, o objetivo do livro consiste em compreender esse fenômeno de reconhecimento externo dos sistemas normativos nacionais através da segunda edição da Teoria de pura do Direito como marco teórico. Igualmente, utiliza-se do estudo de caso sobre a determinação do presidente válido da Venezuela como elemento empírico e de falseabilidade. Com isso, defende a hipótese da necessidade do reconhecimento normativo-objetivo do Estado a partir da formação do Direito internacional, independentemente de seu primitivismo. Os quatro primeiros capítulos, na primeira seção, estabelecem uma interpretação sobre a obra de Kelsen, focada em seu aspecto internacionalista. Nos quatro últimos, na seção II, submeto as conclusões teóricas ao caso concreto, falseando-as ou não conforme seu teste empírico. (shrink)

Nudge is a concept of policy intervention that originates in Thaler and Sunstein's (2008) popular eponymous book. Following their own hints, we distinguish three properties of nudge interventions: they redirect individual choices by only slightly altering choice conditions (here nudge 1), they use rationality failures instrumentally (here nudge 2), and they alleviate the unfavourable effects of these failures (here nudge 3). We explore each property in semantic detail and show that no entailment relation holds between them. This calls into question (...) the theoretical unity of nudge, as intended by Thaler and Sunstein and most followers. We eventually recommend pursuing each property separately, both in policy research and at the foundational level. We particularly emphasize the need of reconsidering the respective roles of decision theory and behavioural economics to delineate nudge 2 correctly. The paper differs from most of the literature in focusing on the definitional rather than the normative problems of nudge. (shrink)

When evidence-based policymaking is so often mired in disagreement and controversy, how can we know if the process is meeting its stated goals? We develop a novel mathematical model to study disagreements about adequate knowledge utilization, like those regarding wild horse culling, shark drumlines and facemask policies during pandemics. We find that, when stakeholders disagree, it is frequently impossible to tell whether any party is at fault. We demonstrate the need for a distinctive kind of transparency in evidence-based policymaking, which (...) we call transparency of reasoning. Such transparency is critical to the success of the evidence-based policy movement, as without it, we will be unable to tell whether in any instance a policy was in fact based on evidence. (shrink)

Environmental ethicists have been arguing for decades that swift action to protect our natural environment is morally paramount, and that our concern for the environment should go beyond its importance for human welfare. It might be thought that the widespread acceptance of moral anti-realism would undermine the aims of environmental ethicists. One reason is that recent empirical studies purport to show that moral realists are more likely to act on the basis of their ethical convictions than anti-realists. In addition, it (...) is sometimes argued that only moral realists can countenance the claim that nature is intrinsically valuable. Against this, we argue that the acceptance of moral anti-realism is no threat to the environmentalist cause. We argue, further, that the acceptance of moral realism is potentially an obstacle to delivering on a third core environmental ethicist demand: namely, that successful action on climate change and environmental destruction requires us to change some of our commonly-held ethical views and to achieve a workable consensus.

A tese defende o antiplatonismo presente na obra do jusfilósofo Hans Kelsen como núcleo argumentativo da sua teoria do direito. Sustenta que a melhor definição da sua filosofia não é como neokantiana, mas como antiplatônica. Isso porque há significativas inconsistências na sua interpretação de Kant, o que a impossibilita de ser classificada como tal. Além, encontra-se na sua leitura sobre Platão referências mais sólidas e conceitos mais claros. Nesse sentido, advoga a hipótese de que a obra de Kelsen tem como (...) constante e como chave de entendimento a sua objeção e contestação às teses de Platão, sobretudo a questão da separação entre alma e corpo, isto é, forma e matéria. O primeiro e segundo capítulos defendem a hipótese da inconsistência das teses de Kelsen sobre Kant. Entende que a sua pressuposição de contradição entre a razão pura e a razão prática, assim como a ideia de uma contradição entre ser e dever-ser, não se sustenta considerando as próprias obras de Kant e a literatura especializada sobre o autor. No segundo capítulo apresenta a sua leitura sobre Platão, concentrada na obra A Ilusão da justiça (Dei Illusion der Gerechtigkeit). O quarto capítulo expõe, sopesando seu antiplatonismo, as duas principais referências teóricas para Kelsen a par de Kant, isto é, as teorias de David Hume e Sigmund Freud. O quinto capítulo demonstra como o antiplatonismo de Kelsen articula com os principais conceitos de suas teses, isto é, mostra que mesmo refutando a classificação do autor como neokantiano, conceitos como norma fundamental, liberdade, o monismo entre direito e Estado, monismo entre direito internacional e nacional e o problema da decisão judicial possuem justificativa e base filosófica coerente. Finalmente, conclui com a possiblidade da ideia de uma teoria kelseniana do direito desvinculada do neokantismo e fundada sobre os pressupostos céticos humeanos e freudianos, tanto moral, quanto teórico, ou seja, reconhece a unidade das obras do autor, desde que condicionada a sua interpretação como antiplatônica.

One justification for preregistering research hypotheses, methods, and analyses is that it improves the transparent evaluation of the severity of hypothesis tests. In this article, I consider two cases in which preregistration does not improve this evaluation. First, I argue that, although preregistration can facilitate the transparent evaluation of severity in Mayo’s error statistical philosophy of science, it does not facilitate this evaluation in Popper’s theory-centric approach. To illustrate, I show that associated concerns about Type I error rate inflation are (...) only relevant in the error statistical approach and not in a theory-centric approach. Second, I argue that a preregistered test procedure that allows deviations in its implementation does not provide a more transparent evaluation of Mayoian severity than a non-preregistered procedure. In particular, I argue that sample-based validity-enhancing deviations cause an unknown inflation of the test procedure’s Type I (familywise) error rate and, consequently, an unknown reduction in its capability to license inferences severely. I conclude that preregistration does not improve the transparent evaluation of severity in Popper’s philosophy of science or when deviations are allowed. (shrink)

A metainference is usually understood as a pair consisting of a collection of inferences, called premises, and a single inference, called conclusion. In the last few years, much attention has been paid to the study of metainferences—and, in particular, to the question of what are the valid metainferences of a given logic. So far, however, this study has been done in quite a poor language. Our usual sequent calculi have no way to represent, e.g. negations, disjunctions or conjunctions of inferences. (...) In this paper we tackle this expressive issue. We assume some background sentential language as given and define what we call an inferential language, that is, a language whose atomic formulas are inferences. We provide a model-theoretic characterization of validity for this language—relative to some given characterization of validity for the background sentential language—and provide a proof-theoretic analysis of validity. We argue that our novel language has fruitful philosophical applications. Lastly, we generalize some of our definitions and results to arbitrary metainferential levels. (shrink)

A subject of a conversation is the social context for the emergence of a doxology as a project of the naturalised theory of knowledge. The Swedish philosopher Mats Rosengren developed the doxology. From his point of view, human knowledge has never been and will never be epistemic (in the Platonic sense). It is always cultural and historical determined, situational and changeable. During the conversation, Rosengren discusses the specifics of the doxological understanding of the constructive nature of scientific knowledge. He speaks (...) about the importance of reception of the French philosophy of the 20th century for the emergence of a doxology. Mats Rosengren gave an interview on June 14, 2018, in Stockholm in the House of the Union of the Swedish writers. Mikael Nydahl did the simultaneous translation from Swedish. Further, Dmitry Vorobev made the transcript and editing of the conversation written text. The paper allows better to understand what the doxology is – as a modern version of the Protagorean theory of knowledge – and what is not. Предметом беседы стал социальный контекст возникновения доксологии – натурализованной теории познания, предложенной шведским философом Матсом Розенгреном. С его точки зрения человеческое знание никогда не было и не будет эпистемическим (в платоновском смысле). Оно всегда культурно-исторически обусловлено, ситуативно, изменчиво. В ходе беседы Розенгрен говорит о специфике доксологического понимания конструктивного характера научного познания, о значении рецепции французской философии XX века для возникновения доксологии. Профессор Розенгрен дал интервью 14 июня 2018 года в Стокгольме в доме Союза шведских писателей. Синхронный перевод с шведского сделал Микаэль Нюдаль. В дальнейшем на базе аудиозаписи беседы Дмитрием Воробьевым был создан и отредактирован текст интервью. Новизна данной работы заключается в том, что она позволяет лучше понять, чем является и чем не является доксология, заявленная ее автором как современный вариант протагорейской теории познания.

Although many libertarians share similar moral foundations, they disagree about whether the state can be justified. The most famous libertarian attempt to justify the state is that of Robert Nozick. This attempt has been criticized by, among others, the libertarian anarchist Murray Rothbard. In this article, Nozick’s theory and Rothbard’s critique are discussed, as well as some other attempts to justify the state from libertarian premises. Keeping the criticisms of those theories in mind, an alternative theory, which attempts to bypass (...) the criticisms, is put forward. This alternative theory explains how a state—most probably a nonminimal democratic state—can legitimately be formed in a condition of anarchy without violating anyone’s libertarian rights. One result of this is that the rights-based case for minarchism is severely weakened. (shrink)

Wicked problems are tricky to solve because of their many interconnected components and a lack of any single optimal solution. At the science–policy interface, all problems can look wicked: research exposes the complexity that is relevant to designing, executing and implementing policy fit for ambitious human needs. Expertise in philosophical research can help to navigate that complexity.

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

It has seemed, to many, that there is an important connection between the ways in which some theoretical posits explain our observations, and our reasons for being ontologically committed to those posits. One way to spell out this connection is in terms of what has become known as the explanatory criterion of ontological commitment. This is, roughly, the view that we ought to posit only those entities that are indispensable to our best explanations. Our primary aim is to argue that (...) the moral nonnaturalist places herself in an invidious position if she simply accepts that the nonnatural moral facts that she posits are not explanatory. Instead, we offer the nonnaturalist an alternative strategy for dealing with moral explanations. The strategy is to retain the explanatory criterion of ontological commitment and maintain that moral properties are, in fact, explanatory. The explanations they provide are not causal explanations; instead, moral properties make a non-causal difference to the physical facts. (shrink)
