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)

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)

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)

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.

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.

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)

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)

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.

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)

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.

Pretendeu-se dissertar acerca do conceito kantiano do Direito a partir da gênese da sua fundamentação moral, ressaltando a aprioricidade da mesma e seu reflexo na doutrina jurídica. Contrariamente ao moral sense da Filosofia empirista inglesa, a moralidade kantiana baseia-se completamente a priori, abdicando de uma antropologia em sua exposição e formulando-se como pura metafísica, a partir de conhecimentos abstratos. Coaduna à concepção de moralidade kantiana o seu conceito de Direito, que também não possui, portanto, qualquer fundamento na experiência. Desta forma, (...) pretende-se fornecer uma interpretação sistemática em relação aos problemas da doutrina do direito, especificamente sobre a sua exterioridade, a função da coerção e a formação do Estado.

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)

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.

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)

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)

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)

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)

Inner speech is commonly understood as the conscious experience of a voice within the mind. One recurrent theme in the scientific literature is that the phenomenon involves a representation of overt speech, for example, a representation of phonetic properties that result from a copy of speech instructions that were ultimately suppressed. I propose a larger picture that involves some embodied objects and their misperception. I call it “the Body Error Theory,” or BET for short. BET is a form of illusionism, (...) but the particular version I favor is a cross-modal illusion. Newly described here, my hypothesis is that the experience of inner speech arises from a mix of interoception and audition. Specifically, there is the detection of slight but well-confirmed activities in the speech musculature that occur during inner speech, which helps to transform representations of normal but quiet nonverbal sounds that inevitably occur during inner speech, from breathing to background noise, into a mistaken perception of inner speech. Simply put, activities in the speech musculature mix with sounds to create the appearance of speech sounds, which thus explains the “voice within the mind.” I also show how BET’s cross-modal system fits with standard information processing accounts for speech monitoring and how it accommodates the central insights of leading theories of inner speech. In addition, I show how BET is supported by data from experience-sampling surveys and how it can be empirically tested against its rivals. (shrink)

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.

Já a Fortuna constitui-se na indeterminabilidade de parte dos resultadosdo governo: ela deve ser dominada, conquistada para o benefício do príncipe.

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)

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.

This paper explores the evolution of consciousness and subjectivity through a biological framework for understanding the universe. It posits that functional patterns in biological systems mirror cosmic mathematical principles, defining our objective reality. Similar to wave and Fibonacci patterns in different physical phenomena, biological patterns are intrinsic to all things and can be quantified using Dedre Gentner’s approach to analogy. For example, Earth’s ocean currents and the melting and freezing of Antarctica resemble the circulatory system and heart, while the production (...) of music from instruments is analogous to ribosomal protein synthesis. Shelves, tables, and chairs function like cytosol by holding objects in space, and a coffee cup mirrors red blood cell distribution. These analogies reveal a universal order rooted in biology’s functional patterns, essential for shaping the emergence and evolution of life. The paper traces the development of consciousness from its rudimentary cellular states to complex human cognition, highlighting the role of biologically-patterned environments in driving evolutionary changes. Organisms that recognized and organized according to these patterns evolved as “pattern recognition engines” crucial for survival—thus, Life (survival) being the primary measure of consciousness. Humans advanced this capacity, gaining cognitive freedom by insulating themselves from environmental constraints, but faced increased subjectivity complexity. Consciousness, while inherently subjective and necessary for cognitive development, evolves in humans to understand objective reality and its biological nature, so to understand and navigate complexities of subjectivity. Ultimately, the paper asserts consciousness is the ability to recognize and adhere to life-sustaining patterns and principles. Successful adherence deems them worthy of continued existence, while failure leads to demise. Parallels with historical concepts like Atman and Brahman in Hinduism suggest ancient recognition of the correspondence between human and universal patterns. This ancient understanding, coupled with modern scientific evidence, reveals the interconnectedness and intrinsic biological nature of reality. (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)

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.

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)

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused attention is (...) needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

Functional reduction follows two familiar steps: a definition of a higher-level or special science property in terms of a functional role, then a statement describing a physical property that plays or occupies that role. But Kim (2005) adds a third step, namely, an explanation regarding how the physical property occupies the functional role. I think Kim is correct. But how is the third step satisfied? An examination of the pertinent scientific explanations reveals that the third step is best satisfied by (...) a multiple-subject, part-whole explanation, which is to say, a decomposition of the occupier’s causal capacities or relations. This is true even in cases wherein role and occupant properties are identical, for an occupier’s causal capacities are always underwritten by a part-whole explanation. As a consequence, functional reduction is transformed into a larger picture that at bottom always contains multiple layers of distinct, nonidentical properties that divide between parts and their whole systems. I call it “Part-Based Functional Reduction.” My aim is to develop this larger picture of reduction. (shrink)

No-one can read far into our subject without finding an author linking aesthetic experience and freedom in one sense or another: Kant, notably of course, but also Schopenhauer, Schiller, and many more. In this article I want first [A] to remind you in a sentence or two of those by now classic ways of connecting concepts of freedom and aesthetic experience, and then [B] to outline some thoughts of my own. Section [C] opens up in more detail a less frequented (...) and less well-charted topic: basically, the many- layered nature of much aesthetic experience, and how that can involve freedom in an ‘improvisatory’ contribution by the apprec iator. Each layer can be thought of as containing a ‘given’—the product of earlier syntheses, plus a new component, in its turn, to be synthesized, whether historical, scientific, religious, or other. This probably occurs most of all in the aesthetic appreciation of nature, since art offers some controlling, ‘mastering’ of the appreciator’s response. (shrink)

It is suggested that the relationship between visual attention and conscious visual experience can be simplified by distinguishing different aspects of both visual attention and visual experience. A set of principles is first proposed for any possible taxonomy of the processes involved in visual attention. A particular taxonomy is then put forward that describes five such processes, each with a distinct function and characteristic mode of operation. Based on these, three separate kinds—or possibly grades—of conscious visual experience can be distinguished, (...) each associated with a particular combination of attentional processes. (shrink)

Humans advanced this capacity, gaining cognitive freedom by insulating themselves from environmental constraints, but faced increased subjectivity complexity. Consciousness, while inherently subjective and necessary for cognitive development, evolves in humans to understand objective reality and its biological nature, so to understand and navigate complexities of subjectivity. Ultimately, the paper asserts consciousness is the ability to recognize and adhere to life-sustaining patterns and principles. Successful adherence deems them worthy of continued existence, while failure leads to demise. Parallels with historical concepts like Atman and Brahman in Hinduism suggest ancient recognition of the correspondence between human and universal patterns. This ancient understanding, coupled with modern scientific evidence, reveals the interconnectedness and intrinsic biological nature of reality. (shrink)

This essay explains Donald Hoffman's Interface Theory of Perception using The Biological Framework for a Mathematical Universe proposed by Ronald Williams. According to Hoffman, what we perceive is more like a “desktop interface with icons representing complex underlying processes, rather than a direct window into the true nature of the world." The theory of a biological framework for a mathematical universes suggests that these complex underlying processes of “the desktop interface with icons” contain correspondences to biological systems. For example, (...) “the desktop icons” of the ocean’s arctic currents and the melting and freezing of Antartica contain “complex underlying processes” which mirror the processes of a circulatory system and beating heart. While indeed we do interpret reality from a superficial perspective as Hoffman suggests, our cognitive abilities are enhanced enough to recognize correspondences to these patterns pertaining to these biological systems which reveal the true nature of the world/universe/reality and thus highlight our evolved perceptual systems which can enable us how to recognize these patterns and organize ourselves to them in order to best survive it. Another example of a “desktop icon” is human society—the order and properties of human society contain “complex underlying processes” that are analogous to the order and properties of cellular society—thus “socioeconomic problems” can be understood through cellular economic problems. Moreover, the solution to the cellular economic problem is the solution to the socioeconomic problem. (shrink)

[Ronald de Sousa] Taking literally the concept of emotional truth requires breaking the monopoly on truth of belief-like states. To this end, I look to perceptions for a model of non-propositional states that might be true or false, and to desires for a model of propositional attitudes the norm of which is other than the semantic satisfaction of their propositional object. Those models inspire a conception of generic truth, which can admit of degrees for analogue representations such as emotions; (...) belief-like states, by contrast, are digital representations. I argue that the gravest problem-objectivity-is not insurmountable. /// [Adam Morton ] It is accuracy rather than truth itself that is valuable. Emotional truth is a dubious though attractive notion, but emotional accuracy is much easier to make sense of. My approach to accuracy goes via an account of what makes a story accurate. Stories can be accurate but not true, and emotions can be accurate whether or not they are true. The capacity for emotional accuracy, for emotions that fit a person's situation, is an aspect of emotional intelligence, which is as important an aspect of rational human agency as the intelligent formation of beliefs and desires.

One of the more powerful impressions created by vision is that of a coherent, richly-detailed world where everything is present simultaneously. Indeed, this impression is so compelling that we tend to ascribe these properties not only to the external world, but to our internal representations as well. But results from several recent experiments argue against this latter ascription. For example, changes in images of real-world scenes often go unnoticed when made during a saccade, flicker, blink, or movie cut. This "change (...) blindness" provides strong evidence against the idea that our brains contain a picture-like representation of the scene that is everywhere detailed and coherent. (shrink)

D. C. Matthew argues that although integration offers blacks social and economic benefits, it also creates the conditions for phenotypic devaluation that leads to harm against black self-worth and servile behavior. Therefore, he advises against integration because the resulting self-worth harms outweigh the benefits of integration. I argue that Matthew’s cost-benefit calculation against integration lacks the requisite evidence, and amounts to a luxury belief that will result in more harm. Moreover, his interpretation of behavior — which he construes as being (...) indicative of a lack of self-worth — is unfounded. Further, his cost-benefit calculation results in socially reactionary sexual policing and ideological purity tests. (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)

Recent advances in our understanding of visual perception have shown it to be a far more complex and counterintuitive process than previously believed. Several important consequences follow from this. First, the design of an effective statistical graphics system is unlikely to succeed based on intuition alone; instead, it must rely on a more sophisticated, systematic approach. The basic elements of such an approach are outlined here, along with several design principles. An overview is then given of recent advances in our (...) understanding of visual perception, including rapid perception, visual attention, and scene perception. It then is argued that the mechanisms involved can be successfully harnessed to allow data to be displayed more effectively than at present. Several directions of development are discussed, including effective use of visual attention, the display of dynamic information, and the effective use of nonattentional and nonconscious perceptual systems.

Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption—which caused stimulus components to become inaccessible to rapid search—was an all-or-nothing effect, and so could serve as a powerful test of grouping. It is shown that these effects are unlikely to be due to blurring by simple spatial filters at (...) early visual levels. It is proposed instead that they are due to more sophisticated processes that rapidly bind contour fragments into spatially-extended assemblies. These results support the view that rapid visual search cannot access the primitives formed at the earliest stages of visual processing; rather, it can access only higher-level, more ecologically-relevant structures.

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.

Over the centuries, magicians have developed extensive knowledge about the manipulation of the human mind—knowledge that has been largely ignored by psychology. It has recently been argued that this knowledge could help improve our understanding of human cognition and consciousness. But how might this be done? And how much could it ultimately contribute to the exploration of the human mind? We propose here a framework outlining how knowledge about magic can be used to help us understand the human mind. Various (...) approaches—both old and new—are surveyed, in terms of four different levels. The first focuses on the methods in magic, using these to suggest new approaches to existing issues in psychology. The second focuses on the effects that magic can produce, such as the sense of wonder induced by seeing an apparently impossible event. Third is the consideration of magic tricks—methods and effects together—as phenomena of scientific interest in their own right. Finally, there is the organization of knowledge about magic into an informative whole, including the possibility of a science centered around the experience of wonder. (shrink)

We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)
