BackgroundBilateral cerebral palsy is the most common type of CP in children and is often accompanied by different degrees of communication impairment. Several studies have attempted to identify children at high risk for communication impairment. However, most prediction factors are qualitative and subjective and may be influenced by rater bias. Individualized objective diagnostic and/or prediction methods are still lacking, and an effective method is urgently needed to guide clinical diagnosis and treatment. The aim of this study is to (...) develop and validate an objective, individual-based model for the prediction of communication impairment in children with BCP by the time they enter school.MethodsA multicenter prospective cohort study will be conducted in four Chinese hospitals. A total of 178 children with BCP will undergo advanced brain magnetic resonance imaging at baseline. At school entry, communication performance will be assessed by a communication function classification system. Three-quarters of children with BCP will be allocated as a training cohort, whereas the remaining children will be allocated as a test cohort. Multivariate lesion- and connectome-based approaches, which have shown good predictive ability of language performance in stroke patients, will be applied to extract features from MR images for each child with BCP. Multiple machine learning models using extracted features to predict communication impairment for each child with BCP will be constructed using data from the training cohort and externally validated using data from the test cohort. Prediction accuracy across models in the test cohort will be statistically compared.DiscussionThe findings of the study may lead to the development of several translational tools that can individually predict communication impairment in children newly diagnosed with BCP to ensure that these children receive early, targeted therapeutic intervention before they begin school.Trial registrationThe study has been registered with the Chinese Clinical Trial Registry.

The assessment of text quality is a transdisciplinary issue concerning the research areas of educational assessment, language technology, and classroom instruction. Text length has been found to strongly influence human judgment of text quality. The question of whether text length is a construct-relevant aspect of writing competence or a source of judgment bias has been discussed controversially. This paper used both a correlational and an experimental approach to investigate this question. Secondary analyses were performed on a large-scale dataset with (...) highly trained raters, showing an effect of text length beyond language proficiency. Furthermore, an experimental study found that pre-service teachers tended to undervalue text length when compared to professional ratings. The findings are discussed with respect to the role of training and context in writing assessment. (shrink)

A conflict of interest is a situation in which a person has competing loyalties or interests that make it difficult to fulfil his or her duties impartially. Conflict of interest is not categorically improper in itself but requires proper management. A SCOPUS literature search was performed for publications on the efficacy/safety of Phospho-Di-Esterase Inhibitors for treating erectile dysfunction. A categorization tool was used to review and classify the publications as supportive/not-supportive for the discussed active ingredient and reporting or not reporting (...) a COI for that specific drug or for the remaining PDEIs. Multivariable binary logistic regression was performed. In the 419 selected records the prevalence of supportive opinions was higher when a COI for the index label was declared. The CoOpCaT showed good internal consistency, discriminative validity and intra/inter-rater agreement. The strongest predictor for a supportive opinion was the total number of financial COIs for the index label. A mild protective effect of the total number of financial COIs for any competitor label was noted. Financial COIs have frequently been associated with bias, and the measures currently adopted to restrain it lack effectiveness. Some evidence for monitoring and/or compensating this bias is reported here, but the ultimate solution remains distant. (shrink)

Adults with chronic pain interpret ambiguous information in a pain and illness related fashion. However, limitations have been highlighted with traditional experimental paradigms used to measure interpretation biases. Whilst ambiguous scenarios have been developed to measure interpretation biases in adolescents with pain, no scenario sets exist for use with adults. Therefore, the present study: sought to validate a range of ambiguous scenarios suitable for measuring interpretation biases in adults, whilst also allowing for two response formats ; and investigate paradigm efficacy, (...) by assessing the effects of recent pain experiences on task responding. A novel ambiguous scenarios task was administered to adults. Participants were presented with 62 ambiguous scenarios comprising 42 that could be interpreted in a pain/pain-illness or non-pain/non-pain illness manner: and 20 control scenarios. Participants generated their own solutions to each scenario, then rated how likely they would be to use two researcher-generated solutions to complete each scenario. Participants also rated their subjective experiences of pain in the last 3 months. Tests of reliability, including inter-rater agreement and internal consistency, produced two ambiguous scenario stimulus sets containing 18 and 20 scenarios, respectively. Further analyses revealed adults who reported more recent pain experiences were more likely to endorse the pain/pain-illness solutions in the Likelihood Ratings Task. This study provides two new stimulus sets for use with adults in pain research and/or interventions. Results also provide evidence for a negative endorsement bias in adults. (shrink)

Peer assessment is employed as one fundamental practice of classroom-based assessment in terms of its learning-oriented and formative nature. The exercise of peer assessment has multiple and additional benefits for student learning. However, research into the learning processes in peer assessment is scarce both in theory and in practice, making it difficult to evaluate and pinpoint its value as a tool in assessment as learning. This study focuses both on the learning process and outcome through assessment activities. We set out (...) with three goals in mind: to examine students' assessment performance in context, to evaluate its impact on student progress, and to illuminate teachers on organizing assessment activities. Three specific research questions are answered in this study: How do student raters perform in the process of PA in an advanced English class? To what extent do assessment activities influence the students' speaking ability? What are students' perceptions of PA regarding its benefits and caveats? A total of 29 undergraduate students participated in two assessment activities on argumentative speaking. Many-Facet Rasch Model analysis was conducted to measure the rater effects both at the group level and the individual level. Bias/interaction analyses were performed to diagnose rater behavior in different contexts including the rating session, speaking session, and peer assessment vs. self-assessment. Questionnaire and semi-structured interview data were also collected to explore factors and strategies that could interfere with PA as AaL. Results show that students exhibited stable rating behavior and made progress in argumentative speaking in all dimensions, including delivery, organization, and language use. They are more stringent with themselves than with peers although there is one rare case with a bias against peers. Participants acknowledged the benefits of PA but also shared reasonable concerns in practice. This study validated the feasibility and the effectiveness of PA for student learning. Discussion on findings and guidelines for effective implementation of PA as AaL are provided. (shrink)

Medical scientists employ ‘quality assessment tools’ (QATs) to measure the quality of evidence from clinical studies, especially randomized controlled trials (RCTs). These tools are designed to take into account various methodological details of clinical studies, including randomization, blinding, and other features of studies deemed relevant to minimizing bias and error. There are now dozens available. The various QATs on offer differ widely from each other, and second-order empirical studies show that QATs have low inter-rater reliability and low inter-tool (...) reliability. This is an instance of a more general problem I call the underdetermination of evidential significance. Disagreements about the strength of a particular piece of evidence can be due to different—but in principle equally good—weightings of the fine-grained methodological features which constitute QATs.

The integration of artificial intelligence into bioethics education represents a new pedagogical approach that addresses complex moral issues in healthcare. The use of AI-driven platforms like ChatGPT in bioethics education can enhance critical thinking and decision-making skills among students by providing a diverse range of perspectives and solutions. To assess the ability of ChatGPT-4 to understand and resolve ethical dilemmas using validated clinical case vignettes, thereby determining its suitability as a teaching aid in bioethics. Ten clinical scenarios, each with inherent (...) ethical issues, were presented to ChatGPT-4. These scenarios were expert-validated to ensure relevance and complexity. ChatGPT's responses were evaluated by two blinded external raters to eliminate bias. The assessment criteria included identification of bioethical principles, recognition of stakeholders and their outcomes, and comprehension of ethical and legal frameworks. Additionally, the quality of responses was scored on a scale of 1–10. ChatGPT showed proficiency in identifying the pertinent bioethical principles and stakeholders involved in the ethical dilemmas presented. It achieved an overall score of 84.5%, with high marks for its analytical capabilities in complex scenarios. However, the study identified areas for improvement, particularly in proposing comprehensive solutions and alternative actions. ChatGPT demonstrates potential as an effective tool for bioethics education, capable of guiding learners through the resolution of ethical issues in clinical practice. However, to fully integrate ChatGPT into bioethics education, it requires enhancements in delivering detailed, actionable guidance in ethical decision-making. Future development should focus on refining ChatGPT’s ability to offer nuanced solutions aligned with patient values and clinician needs. (shrink)

Business ethics journals have appeared on a few ranked lists that are specific to this niche discipline. As with more traditional academic disciplines, these rankings are used for academic rewards such as faculty tenure and promotion, along with department and school ratings. Journal ranking has been subject to considerable criticism even as its administrative use persists. Among the criticisms are that journal quality is a poor proxy for article quality, citation rate is an imperfect reflection of article influence, and (...) class='Hi'>bias may be introduced into rankings by visibility characteristics such as journal age, size, circulation, and experience of the rater with a journal. This research note studies the effect of journal age and size on the rankings of business ethics journals compiled by Beets, Lewis, and Brower, by Albrecht, Thompson, Hoopes, and Rodrigo, and by Serenko and Bontis. Significant correlation was found for journal age with the administratively derived Beets et al. ranking. No significant correlation was found for size in any ranking study. Results were not significant for the Albrecht et al. and the Serenko and Bontis rankings representing the perspectives from surveys of active researchers or citation analysis. Perhaps sometimes a journal’s reputation precedes it, as perception of journal quality may be biased by journal visibility, either because it has been published and available for a number of years, or because it is well known and likely to be cited.

Traditionally, recovered memories of childhood sexual abuse have been classified as those emerging spontaneously versus those surfacing during the course of suggestive therapy. There are indications that reinterpretation of memories might be a third route to recovered memories. Thus, recovered memories do not form a homogeneous category. Nevertheless, the conceptual distinctions between the various types of recovered memories remain difficult for researchers and clinicians. With this in mind, the current study explored whether recovered memories can be reliably classified. We found (...) that classification is rather problematic in a subset of cases. To reduce potential bias, we urge for the development and subsequent use of a more reliable classification system and multiple expert raters in research on recovered memories. (shrink)

BackgroundThe Patient-Centered Outcomes Research Institute is obligated to peer review and to post publicly “Final Research Reports” of all funded projects. PCORI peer review emphasizes adherence to PCORI’s Methodology Standards and principles of ethical scientific communication. During the peer review process, reviewers and editors seek to ensure that results are presented objectively and interpreted appropriately, e.g., free of spin.MethodsTwo independent raters assessed PCORI peer review feedback sent to authors. We calculated the proportion of reports in which spin was identified during (...) peer review, and the types of spin identified. We included reports submitted by April 2018 with at least one associated journal article. The same raters then assessed whether authors addressed reviewers’ comments about spin. The raters also assessed whether spin identified during PCORI peer review was present in related journal articles.ResultsWe included 64 PCORI-funded projects. Peer reviewers or editors identified spin in 55/64 submitted research reports. Types of spin included reporting bias, inappropriate interpretation, inappropriate extrapolation of results, and inappropriate attribution of causality. Authors addressed comments about spin related to 47/55 of the reports.Of 110 associated journal articles, PCORI comments about spin were potentially applicable to 44/110 articles, of which 27/44 contained the same spin that was identified in the PCORI research report. The proportion of articles with spin was similar for articles accepted before and after PCORI peer review.DiscussionJust as spin is common in journal articles and press releases, we found that most reports submitted to PCORI included spin. While most spin was mitigated during the funder’s peer review process, we found no evidence that review of PCORI reports influenced spin in journal articles. Funders could explore interventions aimed at reducing spin in published articles of studies they support. (shrink)

The Fibromyalgia Survey Questionnaire was self-administered by a sample of 207 Italian individuals with obesity to screen for fibromyalgia. We aimed to investigate the inter-rater reliability and the agreement in the detection of FM symptomatology between the self-administered FSQ and the clinical interview conducted by a rheumatologist. All the patients were divided randomly into two groups : a rheumatologist first interviewed patients of group A and after 48 h, the patients completed the self-report FSQ. Patients of group B first (...) completed the FSQ and 48 h later were interviewed by a rheumatologist. The agreement between the measurements was good with the Bland-Altman analysis showing low bias scores for the two subscales of the FSQ. Results showed that 33% of the sample satisfied the criteria for a diagnosis of fibromyalgia. The FSQ is a self-reporting measure that showed substantial reliability providing fast screening for FM symptomatology. (shrink)

Gender discrimination continues to be a problem in organizations. It is therefore important that organizations use performance evaluation methods that ensure equal opportunities for men and women. This article reports the results of an experiment to investigate whether and, if so, how the gender of the rater and that of the ratee moderate the relationship between the level of subjectivity in performance appraisals and organizational attractiveness. Participants in the experiment were 313 undergraduate students. We predicted, and indeed established, that (...) as the probability increases that employee performance is evaluated by a female manager, women expect more positive outcomes of subjective, but not objective evaluation processes. Our data did not support our expectation that as the probability of being evaluated by a female manager increases, men expect less positive outcomes of subjective evaluation processes. The findings of this study contribute to our understanding of why women are over-represented in jobs with objective formula-based reward systems, such as piece-rate systems. They are also of interest to organizations that are looking for more ethical human resource management practices. (shrink)

Most arguments of Applied Ethics are well analyzed. An exception is the argument 'I do not do this because it is not my duty'. It makes sense to call the argument the 'argument of supererogation' : Since J. Urmson's essay Saints and Heroes of 1958, those actions are called 'supererogations' which are not supposed to be duties. The argument is widely used not only in Applied Ethics, but also in ordinary moral everyday life. Nevertheless, there is a need of investigation (...) because it has an indecency-problem. The argument is convincing if an actor does not want to risk his life. It seems indecent, however, if an actor refuses a simple favor or a service of friendship with the 'argument of super-erogation', although they both constitute no duties. This paper reconstructs the 'argument of supererogation' as a syllogism. It analyzes its formal structure by benefitting from current Anglo-American literature on supererogation. The overall aim of this paper is to solve the problem of indecency. (shrink)

In his 1939 essay, “Some Questions on Dewey’s Aesthetics,” Stephen Pepper gave the following assessment of Dewey’s Art as Experience of 1934: “We are deprived of a pragmatic theory of ugliness” because Dewey “was reverting to Hegelianism in his later years.” By ‘Hegelianism’ Pepper meant the Second Oxford Hegelianism of Bernard Bosanquet. Similarly, Dale Jacquette wrote in 1984 that “nothing is ugly” in Bosanquet’s Three Lectures on Aesthetics, a work that Jacquette sees as bearing the influence of Hegel. But neither (...) critic has taken into account the following: Hegel and Bosanquet both employ an aesthetic-technical as well as a conventional concept of ‘beauty.’ In order to call an artwork ‘aesthetically excellent,’ both thinkers refer to artwork in an aesthetic-technical sense as ‘beautiful artwork.’ However, artworks that are beautiful in the aesthetic-technical sense can be ugly in the conventional sense. In order to evaluate the potential of a Hegelian aesthetic of the ugly, a distinction must be made between the aesthetic-technical and the conventional use of the terms ‘beautiful’ and ‘ugly’ in both Hegel and Bosanquet. And this the early Bosanquet — i.e., the Bosanquet of the 1892 A History of Aesthetic — did not see in Hegel. (shrink)

ZusammenfassungViele Menschen erwarten Dankbarkeit von den Geflüchteten, die in Europa aufgenommen werden. Nun kann mit dem Satz „Geflüchtete sollen dankbar sein“ eine moralische Pflicht oder ein Ratschlag gemeint sein. Mein Essay zeigt in einem ersten Schritt, dass es keine Pflicht zur Dankbarkeit geben kann. Dankbarkeit ist vielmehr Supererogation, nämlich eine moralisch wertvolle Handlungsweise, die keine Pflicht sein kann. Das gilt auch für Geflüchtete. Anschließend zeige ich, dass Dankbarkeit als sympathischer Ausdruck einer Tugendhaltung jedermann anzuraten ist. Wer sich für erwiesene Wohltaten (...) dankbar zeigt, wird gemocht und geschätzt. Das gilt wiederum auch für Geflüchtete. Mein Essay schließt mit einem kurzen Ausblick zu der Frage, wofür und in welchem Umfang Geflüchteten Dankbarkeit anzuraten ist. (shrink)

Over millennia, epidemics have wielded as much sway over human affairs as have wars, economic crises, and political upheavals. Devastating epidemics in the past have changed the course of history. This article focuses on the yellow fever epidemic of 1802 in St. Domingue to demonstrate how science has deepened our understanding of the epidemic, and hence of the Haitian Revolution. Genetics, affirming epidemiology, demonstrated that the origin of the virus was in Africa, and genomics demonstrated that the vector of yellow (...) fever, the _Aedes aegypti_ mosquito, evolved in the context of the ecological creation of the Sahara and the Sahel. The vector fed on humans and reproduced in man-made water containers, allowing transport to the Caribbean during the African slave trade. Serological studies in Africa later demonstrated that many African-origin slaves would have had adaptive immunity. French fighters did not, and they were decimated. The French withdrew, Haiti was created, and the Louisiana Purchase was executed. (shrink)

It is commonplace by now that moral philosophy has a long history of gender biases, not only regarding the pertinent moral issues but also regarding the development of concepts and theories. This insight from feminist philosophy, however, has not yet received sufficient attention in the debate on supererogation. That is not least surprising, since we all are familiar with the phenomenon that what is morally expected of an agent is not gender-neutral but at least to some extent relates to gender (...) roles and social expectations. Therefore, the main aim of this chapter is to build on theoretical and methodological insights from feminist philosophy to carve out this research gap and to map the field for future research. It will be argued that feminist approaches can only be ignored within the debate on supererogation at the cost of philosophical rigor since they do not only give rise to novel perspectives and insights on questions already discussed, but also make matters visible that would have been overlooked otherwise. Thereby this chapter seeks essentially to contribute to a more extensive understanding of the social, political, and epistemic dimensions of supererogation that have hitherto been neglected.

Das Handbuch Angewandte Ethik soll folgenden beiden Interessen Rechnung tragen: sowohl dem allgemeinen Informationsbedarf, beispielsweise von Journalisten, Politikern, Rechtswissenschaftlern und Fachleuten der jeweils betroffenen Disziplinen, als auch dem spezifischen der Kolleginnen und Kollegen, Studierenden und Lehrenden in der Angewandten Ethik. Entsprechend öffnen die neun Teile des Buches mehrere Zugangswege in das Handbuch. Nicht nur der Aufbau des Handbuchs ist mehrdimensional, auch die Beiträge stammen aus unterschiedlichen Bildungshintergründen und Arbeitskontexten. So wie die Angewandte Ethik durch die verschiedenen Fächer und Traditionen geprägt (...) ist, aus denen ihre Vertreterinnen und Vertreter stammen, so lassen auch die Kapitel dieses Handbuchs deutlich die persönliche Handschrift und Haltung der einzelnen Autorinnen und Autoren erkennen.

Das Handbuch erfasst die Angewandte Ethik systematisch und historisch, beschreibt ihre rechtliche und institutionelle Situation sowie die relevanten Teilbereiche, wie z.B. Forschungs-, Wirtschafts- und Bioethik. Im Zentrum stehen konkrete Fragen aus dem Privat- und Sozialleben des Menschen, der medizinischen Ethik sowie der Umwelt- und Tierethik.

Considerable attention has focused on studying reviewer agreement via inter-rater reliability (IRR) as a way to assess the quality of the peer review process. Inspired by a recent study that reported an IRR of zero in the mock peer review of top-quality grant proposals, we use real data from a complete range of submissions to the National Institutes of Health and to the American Institute of Biological Sciences to bring awareness to two important issues with using IRR for assessing (...) peer review quality. First, we demonstrate that estimating local IRR from subsets of restricted-quality proposals will likely result in zero estimates under many scenarios. In both data sets, we find that zero local IRR estimates are more likely when subsets of top-quality proposals rather than bottom-quality proposals are considered. However, zero estimates from range-restricted data should not be interpreted as indicating arbitrariness in peer review. On the contrary, despite different scoring scales used by the two agencies, when complete ranges of proposals are considered, IRR estimates are above 0.6 which indicates good reviewer agreement. Furthermore, we demonstrate that, with a small number of reviewers per proposal, zero estimates of IRR are possible even when the true value is not zero. (shrink)

The Ethics Consultation Quality Assessment Tool (ECQAT) establishes standards by which the quality of ethics consultation records (ECRs) can be assessed. These standards relate to the ethics question, consultation-specific information, ethical analysis, and recommendations and/or conclusions, and result in a score associated with one of four levels of ethics consultation quality. For the ECQAT to be useful in assessing and improving the quality of healthcare ethics consultations, individuals who rate the quality of ECRs need to be able to reliably use (...) the tool.We developed a short course to train ethics consultants in using the ECQAT, and evaluated whether the participants (1) achieved an acceptable level of calibration in matching expert-established quality scores for a set of ethics consultations, and (2) were satisfied with the course. We recruited 28 ethics consultants to participate in a virtual, six-session course. At each session participants and faculty reviewed, rated, and discussed one to two ECRs. The participants’ calibration in matching expert-established quality scores improved with repeated exposure at all levels of ethics consultation quality. Participants were generally more accurate when assessing consultation quality at the dichotomous level of “acceptable” (scores of three or four) versus “unacceptable” (scores of one or two) than they were with a more specific score. Participants had higher rates of accuracy with the extreme ratings of “strong” (level four) or “poor” (level one). Although participants were highly satisfied with the course, only a minority of participants achieved the prespecified acceptable level of calibration (that is, 80 percent or greater accuracy between their score and expert-established scores). These results suggest that ECQAT training may require more sessions or need modification in the protocol to achieve higher reliability in scoring. Such trainings are an important next step in ensuring that the ECQAT is a tool that can be used to promote improvement in ethics consultation quality. (shrink)

Young, middle-aged, and older raters (N=154) evaluated 1,026 prototypical facial poses of neutrality, happiness, anger, disgust, fear, and sadness stemming from 171 young, middle-aged, and older posers. The majority of poses were rated as multi-faceted, that is, to comprise several expressions of varying intensities. Consistent with the notion of age-related increases in negativity–avoidance/positivity effects, crossed-random effects analyses showed an age-related decrease in the attributions of negative, but not positive and neutral, target expressions (that the poser intended to show), and an (...) age-related increase in the attributions of positive and neutral, but not negative, non-target expressions (that the posers did not intend to show). Expressions were more difficult to read the older the posers, particularly for male posers. These age-of-poser effects were independent of the valence of the expression, but partly differed across age groups of raters. The study supports the idea of multi-dimensionality and age-dependency of emotion perception. (shrink)

What is the mental representation that is responsible for implicit bias? What is this representation that mediates between the trigger and the biased behavior? My claim is that this representation is neither a propositional attitude nor a mere association. Rather, it is mental imagery: perceptual processing that is not directly triggered by sensory input. I argue that this view captures the advantages of the two standard accounts without inheriting their disadvantages. Further, this view also explains why manipulating mental imagery (...) is among the most efficient ways of counteracting implicit bias. (shrink)

When interests and preferences of researchers or their sponsors cause bias in experimental design, data interpretation or dissemination of research results, we normally think of it as an epistemic shortcoming. But as a result of the debate on science and values, the idea that all extra-scientific influences on research could be singled out and separated from pure science is now widely believed to be an illusion. I argue that nonetheless, there are cases in which research is rightfully regarded as (...) epistemologically deficient due to the influence of preferences on its outcomes. I present examples from biomedical research and offer an analysis in terms of social epistemology. (shrink)

This book is a philosophical exploration of bias and our practices of attributing it. It develops and defends the norm-theoretic account of bias, according to which objectionable biases involve systematic departures from objective norms or standards of correctness. It explores the perspectival character of bias attributions, or the ways in which our views about which people and sources of information are biased about a topic are influenced and constrained, both rationally and psychologically, by our views about the (...) topic itself. The book defends a robust pluralism about bias, according to which a radical diversity of things are genuinely biased, with none of these more fundamental than all of the rest. Biases of people are understood as multiply realizable dispositions to depart from objective norms. It offers a novel account of the bias blind spot, or our tendency to fail to see bias in ourselves in a way that we see it in others. It explores the connections between bias and central topics in the theory of knowledge, including truth, knowledge, rationality, reliability, introspection, skepticism, and disagreement. A number of racial conclusions are defended: that both rationality and morality sometimes require us to be biased; that in many cases of disagreement, we are rationally required to view those who disagree with us as biased, even if we know nothing about how they arrived at their views or why they hold them; and that even God could not have made us reliable detectors of our own biases through introspection.

This paper examines the role of prestige bias in shaping academic philosophy, with a focus on its demographics. I argue that prestige bias exacerbates the structural underrepresentation of minorities in philosophy. It works as a filter against (among others) philosophers of color, women philosophers, and philosophers of low socio-economic status. As a consequence of prestige bias our judgments of philosophical quality become distorted. I outline ways in which prestige bias in philosophy can be mitigated.

Elongation bias is consumer’s faulty perception toward a product. Elongation bias happens on visual, touch, and hearing senses. This research focused on product of tea that bottled in different kind of container and volume. Results on visual perception show that elongation bias exists in subject’s perception about the volume of tea. A taller bottle is always perceived has a greater volume than a shorter one. Therefore for the economical reason, with the same price of tea, subjects prefer (...) to buy a taller bottle.  . (shrink)

Many philosophers appeal to intuitions to support some philosophical views. However, there is reason to be concerned about this practice as scientific evidence has documented systematic bias in philosophically relevant intuitions as a function of seemingly irrelevant features (e.g., personality). One popular defense used to insulate philosophers from these concerns holds that philosophical expertise eliminates the influence of these extraneous factors. Here, we test this assumption. We present data suggesting that verifiable philosophical expertise in the free will debate-as measured (...) by a reliable and validated test of expert knowledge-does not eliminate the influence of one important extraneous feature (i.e., the heritable personality trait extraversion) on judgments concerning freedom and moral responsibility. These results suggest that, in at least some important cases, the expertise defense fails. Implications for the practice of philosophy, experimental philosophy, and applied ethics are discussed.

Philosophers have long noted, and empirical psychology has lately confirmed, that most people are “biased toward the future”: we prefer to have positive experiences in the future, and negative experiences in the past. At least two explanations have been offered for this bias: belief in temporal passage and the practical irrelevance of the past resulting from our inability to influence past events. We set out to test the latter explanation. In a large survey, we find that participants exhibit significantly (...) less future bias when asked to consider scenarios where they can affect their own past experiences. This supports the “practical irrelevance” explanation of future bias. It also suggests that future bias is not an inflexible preference hardwired by evolution, but results from a more general disposition to “accept the things we cannot change”. However, participants still exhibited substantial future bias in scenarios in which they could affect the past, leaving room for complementary explanations. Beyond the main finding, our results also indicate that future bias is stake-sensitive and that participants endorse the normative correctness of their future-biased preferences and choices. In combination, these results shed light on philosophical debates over the rationality of future bias, suggesting that it may be a rational response to empirical realities rather than a brute, arational disposition.

An important assumption underlying meaningful comparisons of scores in rater-mediated assessments is that measurement is commensurate across raters. When raters differentially apply the standards established by an instrument, scores from different raters are on fundamentally different scales and no longer preserve a common meaning and basis for comparison. In this study, we developed a method to accommodate measurement noninvariance across raters when measurements are cross-classified within two distinct hierarchical units. We conceptualized random item effects cross-classified graded response models and (...) used random discrimination and threshold effects to test, calibrate, and account for measurement noninvariance among raters. By leveraging empirical estimates of rater-specific deviations in the discrimination and threshold parameters, the proposed method allows us to identify noninvariant items and empirically estimate and directly adjust for this noninvariance within a cross-classified framework. Within the context of teaching evaluations, the results of a case study suggested substantial noninvariance across raters and that establishing an approximately invariant scale through random item effects improves model fit and predictive validity.
