Current fears of a “reproducibility crisis” have led researchers, sources of scientific funding, and the public to question both the efficacy and trustworthiness of science. Suggested policy changes have been focused on statistical problems, such as p-hacking, and issues of experimental design and execution. However, “reproducibility” is a broad concept that includes a number of issues. Furthermore, reproducibility failures occur even in fields such as mathematics or computer science that do not have statistical problems or issues with (...) experimental design. Most importantly, these proposed policy changes ignore a core feature of the process of scientific inquiry that occurs after reproducibility failures: the integration of conflicting observations and ideas into a coherent theory.

We philosophically discuss phenomena that occur when computational technology reaches a technological singularity and triggers an intelligence explosion, realizing an AI to produce AI by themselves. By providing a philosophical definition of superintelligence, we estimate the change of societal values. While AI agents are moving toward superintelligence, their ability to produce artificial reality approaches the technological critical point where their capability exceeds that of biological entities to distinguish between the empirical reality and AR. As Self-Reproducing Machines improve by themselves, we (...) consider that society moves to the ambiguous condition executed by the undetectable intervention by superintelligence. Although this is similar to the ideal capitalism, it is not able to be simply classified such as the current executed capitalism, socialism, or communism. In contrast to singularitalianism which mainly focuses on technological singularity, we propose to call the principle after singularity until criticality as criticalitalianism. (shrink)

In this paper, we show that reproducibility is a severe problem that concerns simulation models. The reproducibility problem challenges the concept of numerical solution and hence the conception of what a simulation actually does. We provide an expanded picture of simulation that makes visible those steps of simulation modeling that are numerically relevant, but often escape notice in accounts of simulation. Examining these steps and analyzing a number of pertinent examples, we argue that numerical solutions are importantly different (...) from usual mathematical solutions. They are do not merely approximate the latter, but introduce new problems, including issues of artificiality, stability, and well-posedness. Consequently, simulation modelling can attain reproducibility only to a certain degree because it is working with numerical solutions. (shrink)

Computational reproducibility possesses its own dynamics and narratives of crisis. Alongside the difficulties of computing as an ubiquitous yet complex scientific activity, computational reproducibility suffers from a naive expectancy of total reproducibility and a moral imperative to embrace the principles of free software as a non-negotiable epistemic virtue. We argue that the epistemic issues at stake in actual practices of computational reproducibility are best unveiled by focusing on software as a pivotal concept, one that is surprisingly (...) often overlooked in accounts of reproducibility issues. Software is not only about designing and coding but also about maintaining, supporting, distributing, licensing, and governance; it is not only about developers but also about users. We focus on openness debates among computational chemists involved in molecular modeling software packages as empirical grounding for our argument. We then identify and analyse four epistemic characteristics as key to the role of software in computational reproducibility. (shrink)

The reproducibility movement in psychology has resulted in numerous highly publicized instances of replication failures. The goal of the present work was to investigate people’s reactions to a psychology replication failure vs. success, and to test whether a failure elicits harsher reactions when the researcher is a woman vs. a man. We examined these questions in a pre-registered experiment with a working adult sample, a conceptual replication of that experiment with a student sample, and an analysis of data compiled (...) and posted by a psychology researcher on their public weblog with the stated goal to improve research replicability by rank-ordering psychology researchers by their “estimated false discovery risk.” Participants in the experiments were randomly assigned to read a news article describing a successful vs. failed replication attempt of original work from a male vs. female psychological scientist, and then completed measures of researcher competence, likability, integrity, perceptions of the research, and behavioral intentions for future interactions with the researcher. In both working adult and student samples, analyses consistently yielded large main effects of replication outcome, but no interaction with researcher gender. Likewise, the coding of weblog data posted in July 2021 indicated that 66.3% of the researchers scrutinized were men and 33.8% were women, and their rank-ordering was not correlated with researcher gender. The lack of support for our pre-registered gender-replication hypothesis is, at first glance, encouraging for women researchers’ careers; however, the substantial effect sizes we observed for replication outcome underscore the tremendous negative impact the reproducibility movement can have on psychologists’ careers. We discuss the implications of such negative perceptions and the possible downstream consequences for women in the field that are essential for future study. (shrink)

BackgroundThe objective of this study was to evaluate the nature and extent of reproducible and transparent research practices in neurology publications.MethodsThe NLM catalog was used to identify MEDLINE-indexed neurology journals. A PubMed search of these journals was conducted to retrieve publications over a 5-year period from 2014 to 2018. A random sample of publications was extracted. Two authors conducted data extraction in a blinded, duplicate fashion using a pilot-tested Google form. This form prompted data extractors to determine whether publications provided (...) access to items such as study materials, raw data, analysis scripts, and protocols. In addition, we determined if the publication was included in a replication study or systematic review, was preregistered, had a conflict of interest declaration, specified funding sources, and was open access.ResultsOur search identified 223,932 publications meeting the inclusion criteria, from which 400 were randomly sampled. Only 389 articles were accessible, yielding 271 publications with empirical data for analysis. Our results indicate that 9.4% provided access to materials, 9.2% provided access to raw data, 0.7% provided access to the analysis scripts, 0.7% linked the protocol, and 3.7% were preregistered. A third of sampled publications lacked funding or conflict of interest statements. No publications from our sample were included in replication studies, but a fifth were cited in a systematic review or meta-analysis.ConclusionsCurrently, published neurology research does not consistently provide information needed for reproducibility. The implications of poor research reporting can both affect patient care and increase research waste. Collaborative intervention by authors, peer reviewers, journals, and funding sources is needed to mitigate this problem. (shrink)

I discuss reproducibility issues in animal-based research in biomedicine and scrutinise the notion that the causes of non-reproducible results are, by and large, the same as in other disciplines. I argue that there are certain challenges of animal experimentation that are important for a proper analysis of reproducibility problems but have not been sufficiently analysed in this context. I focus on challenges related to standardisation practices and trade-offs between epistemic ideals and moral considerations in animal experimentation. Using an (...) approach that integrates epistemological and ethical perspectives, I explore these challenges and draw out normative consequences of my analysis for the discussion revolving around questionable research practices in animal-based biomedicine and generic reform initiatives.

A review of the scientific method. In the scientific method, results must be capable of being reproduced to be valid.

The ‘Sixth Report—Reproducibility and Research Integrity’ (UK House of Commons Science, Innovation and Technology Committee 2023. ‘Sixth Report—Reproducibility and Research Integrity’) (‘The Report’) recommends measures designed to tackle an alleged ‘reproducibility crisis’ in scientific research. Our systematic analysis of the content of this report revealed that its findings and recommendations are consistent with the scientific literature, including the acknowledgement that conclusive evidence demonstrating the existence of a ‘reproducibility crisis’ is lacking. Though conceding that there is currently (...) no way to determine the size of the crisis or whether it even exists, The Report nevertheless proposes actions to tackle the alleged crisis. However, without a quantitative understanding, the efficacy of the proposed measures cannot be verified. Hence, the current approach towards the alleged reproducibility crisis, here exemplified by The Report, does not adhere to the standards that would normally applied to the scientific method. An evidence-based approach requires the establishment of a quantitative understanding of whether data variability in the research literature exceeds technically achievable levels of reproducibility. If it does, the resulting understanding will enable the design of actions, whose success can be monitored. Our findings emphasise that the research environment requires the same level of rigour and scrutiny as the scientific experiments themselves. (shrink)

Current report assessed measurement reproducibility and reliability of magnetic resonance spectroscopy (1H-MRS) at 3 Tesla in left and right posterior insular, pregenual and anterior midcingulate subdivisions. 10 healthy male volunteers aged 20 to 30 years were tested on four different days, of which 9 were included in the data analysis. Intra- and inter-subject variability of myo-Inositol (mI), Creatine (Cre), Glutamate (glu), total-Choline (tCho), total-N-acetylaspartate (tNAA) and combined Glutamine-Glutamate (Glx) were calculated considering the influence of movement parameters, age, daytime of (...) measurements and tissue composition. Overall mean intra-subject variability revealed small mean coefficients of variation (CV) across the four regions: 5.3% in aMCC, 6.6% in pgACC, 7.3% in pIL and 8.2% in pIR. For all neurochemicals combined, mean inter-subject variability demonstrated mean CVs of 9.05% (aMCC), 8.84% (pgACC), 10.00% (pIL) and 10.55% (pIR). Head movement, tissue composition and day time revealed no significant explanatory variance contribution suggesting a negligible influence on data. A strong correlation between Cramer-Rao Lower Bounds (CRLB; a measure of fitting errors) and the mean intra-subject CV (r=0.799, p<0.001) outlined the importance of low CRLB in order to obtain robust and finally meaningful 1H-MRS measures. The present findings confirm 1H-MRS as a reliable tool to measure brain neurochemistry in small subregions of the human brain. (shrink)

This paper investigates the concept of reproduction in an evolutionary context. It draws a distinction between objects that are reproduced (reproducees), objects that reproduce thanks to some reproductive autonomy (reproducers), and Darwinian individuals that are reproducers with a high degree of reproductive causal control. This threefold distinction is then applied to different biological objects classically invoked in reproduction processes (e.g., genes, viruses, cells) to explain why they do not have the same status with respect to reproduction. The distinction also provides (...) some fuel for the view proposed by Griesemer: that material overlap during reproduction is a condition for reproduction. (shrink)

The author uses census data to assess the consequences of two alternative theoretical formulations of care work for understanding the intersections of gender, race, and economic inequalities in paid care. The nurturance conceptualization focuses on care as relationship while the reproductive labor framework includes both relational and nonrelational jobs that maintain and reproduce the labor force. An empirical application of both models to the labor market shows that placing increasing theoretical emphasis on nurturant care privileges the experiences of white women (...) and excludes large numbers of very-low-wage workers from consideration.

In his influential book, "Changing Order", H.M. Collins puts forward the following three claims concerning experimental replication. (i) Replication is rarely practiced by experimentalists; (ii) replication cannot be used as an objective test of scientific knowledge claims, because of the occurrence of the so-called experimenters' regress; and (iii) stopping this regress at some point depends upon the enculturation in a local community of practitioners, who tacitly learn the relevant skills. In my paper I discuss and assess these claims on the (...) basis of a more comprehensive analysis of experimentation and experimental reproducibility. The main point is that Collins' claims are not, strictly speaking, wrong, but rather too one-sided and therefore inadequate. This point also calls for a reconsideration of the radical (social constructivist) conclusions that Collins has drawn from his studies of scientific experimentation. (shrink)

The reproductive rights of women have been a central topic in feminist bioethics. The focus has been predominantly on the right not to reproduce, and so not to be subject to pronatalist social forces that make motherhood compulsory for women. That is the case despite many women and other members of marginalized groups experiencing anti-natalism, or in other words, social pressure to avoid biological reproduction. For these groups, the right to reproduce is as important, if not more important, than the (...) right not to reproduce. This chapter concentrates on the right to reproduce and considers what form it should take in feminist bioethics. The main claim of the chapter is that feminists should ground the right in the need to protect marginalized groups from anti-natalism. (shrink)

A methodological imperative, reproducibility, is proposed for experimental research. This is motivated by recent discussions of normative naturalism as well as the recent interest in the philosophical implications of experimental research. The role of this norm is examined in the context of the routine research procedures in a high-energy scattering experiment. The specific details of the experimental analysis of resonance production in the interaction π +P→ Pπ + π + π - π 0 at 18.5 Ge V/c are discussed (...) in light of the importance of reproducing experimental results. In this context, a more complex meaning of this norm emerges. It is suggested that this type of empirical evaluation of hypothetical imperatives should be at the core of the normative naturalist's program. (shrink)

The American Sign Language Sentence Reproduction Test (ASL-SRT) requires the precise reproduction of a series of ASL sentences increasing in complexity and length. Error analyses of such tasks provides insight into working memory and scaffolding processes. Data was collected from three groups expected to differ in fluency: deaf children, deaf adults and hearing adults, all users of ASL. Quantitative (correct/incorrect recall) and qualitative error analyses were performed. Percent correct on the reproduction task supports its sensitivity to fluency as test performance (...) clearly differed across the three groups studied. A linguistic analysis of errors further documented differing strategies and bias across groups. Subjects' recall projected the affordance and constraints of deep linguistic representations to differing degrees, with subjects resorting to alternate processing strategies when they failed to recall the sentence correctly. A qualitative error analysis allows us to capture generalizations about the relationship between error pattern and the cognitive scaffolding, which governs the sentence reproduction process. Highly fluent signers and less-fluent signers share common chokepoints on particular words in sentences. However, they diverge in heuristic strategy. Fluent signers, when they make an error, tend to preserve semantic details while altering morpho-syntactic domains. They produce syntactically correct sentences with equivalent meaning to the to-be-reproduced one, but these are not verbatim reproductions of the original sentence. In contrast, less-fluent signers tend to use a more linear strategy, preserving lexical status and word ordering while omitting local inflections, and occasionally resorting to visuo-motoric imitation. Thus, whereas fluent signers readily use top-down scaffolding in their working memory, less fluent signers fail to do so. Implications for current models of working memory across spoken and signed modalities are considered. (shrink)

Breeding companion animals as well as allowing them to reproduce is controversial. In this chapter three kinds of argument for an alternative course of action are presented, namely preventing companion animals from reproducing, usually by sterilization. These are anti-natalist arguments, abolitionist arguments, and harm prevention arguments. The anti-natalist and abolitionist arguments are categorically opposed to all breeding of companion animals. The harm prevention argument, on the other hand, is a conditional one, according to which people should desist from breeding companion (...) animals until such time as the demand for such animals exceeds the number of these animals already in existence. However, given how many unwanted animals there currently are, people are nowhere near that point. Thus, all three arguments converge on the conclusion that reproducing companion animals is wrong. The case against breeding companion animals is significantly overdetermined. (shrink)

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our (...) sample – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Exploring whether clades can reproduce leads to new perspectives on general accounts of biological development and individuation. Here we apply James Griesemer's general account of reproduction to clades. Griesemer's account of reproduction includes a requirement for development, raising the question of whether clades may bemeaningfully said to develop. We offer two illustrative examples of what clade development might look like, though evaluating these examples proves difficult due to the paucity of general accounts of development. This difficulty, however, is instructive about (...) what a general account of development should look like and how it may usefully be applied to research problems (further suggesting a means for evaluating general accounts of development). Reproduction also requires individuation of parent and offspring. We argue that there is no special problem of individuating older and younger clades. The vagaries involved with determining when clades begin, mature, and end are precisely the same as those that arise when the same questions are asked of cells, organisms, or species. Though the question of clade reproduction and selection may still be open, the process of discovery presents new insights into old problems. (shrink)

Despite shifts in science policy and funding modalities, international research collaborations continue to be shaped by inequalities that structure global science. These include a skewed division of tasks and unequal scientific authority in North-South partnerships. Existing scholarship highlights scholars’ experiences of such inequalities, but offers little explanation of how they are reproduced and affect joint knowledge production. We address this gap with an empirical study of six African-European research projects on forests. Drawing on Bourdieu’s sociology of science, we employ a (...) praxeological methodology that includes participant observation in collaborative meetings, analysis of project-related documents and reflexive interviews with scholars involved. We show discrepancies between how collaborators’ relations were designed and practiced: Even when projects had been set up as equal partnerships aimed at joint knowledge making, the emerging collaboration orders tended to reflect differential roles and unequal authority in epistemic choices. While African scholars exerted authority over field work, European scholars directed the ‘how to’ of conducting forest governance research. We explain the continuity of this pattern with Bourdieu’s notion of the habitus: a practical sense of roles scholars have internalised, resulting from their positions in global science and the capitals (economic, scientific, social, symbolic) they are endowed with. The study illuminates how and why inequalities in research collaborations persist, regardless of formal project constellations and contrary to individual intentions. It highlights the potential of Bourdieusian theory for empirical science studies, with habitus as a concept explaining discrepancies between desired forms of collaboration and actual collaboration practice.

ABSTRACTHow should we conceive of a right to reproduce? And, morally speaking, what might be said to justify such a right? These are just two questions of interest that are raised by the technologies of assisted reproduction. This paper analyses the possible legitimate grounds for a right to reproduce within the two main theories of rights; interest theory and choice theory.

This article investigates the critical potential of a contemporary dystopia, The Handmaid’s Tale (Miller 2017-), a U.S. television series adapted from a popular novel by Canadian author Margaret Atwood (1985). The text is widely understood as a feminist intervention that speaks to ongoing struggles against gender oppression, but in this article I consider the invitations that the show offers its viewers in treating race the way that it does, and consider what it means to refuse these invitations in pursuit of (...) a critical feminist understanding of authority, legal subjectivity, and violence. Drawing on the recent turn to genre, my reading focuses on how whiteness is reproduced through this cinematic text and its inculcation of particular ways of seeing, modes of identification and attachment. The Handmaid’s Tale’s post-racial aesthetic means that its thematic engagement with gender, sexuality and resistance actively disavows national and international histories of racist state violence and white supremacy. Its problematic feminism is thus uniquely instructive for understanding how whiteness is reproduced in contemporary (neo)liberal configurations of legal subjectivity and state authority. (shrink)

Human knowledge would benefit greatly if images of all works of art in the public domain - i.e. those for which the creator's copyright has expired - were readily available on the web. Scholars pay a high price in reproduction fees to illustrate their articles, while institutions profit from the exposure their collections and archives are given in the pages of scholarly publications. Legal and commercial forces of regulation and licensing are attempting to extend their control over copyright at a (...) time when digital technology makes the dissemination, downloading and reproducing of electronically generated and scanned images easier than it has ever been. Some collections of photographic images of works of art are charging high fees in situations where their right to claim ‘ownership’ is contentious. The author argues, with reference to the work of Robert Baron, that because digitization has made control of intellectual property a for-profit business, the net result could be an undermining of public domain. Subscription deals with non-profit institutions could be a fairer way forward, and ARTstor is cited as a positive example. (shrink)

Focusing on a textbook controversy that emerged in Kanawha County, West Virginia, in 1974, Mason explores the discursive production of white ethnicity in the rhetorical, visual, and political strategies used during an organized protest against the new multicultural curriculum adopted by the local school board. What the author finds puzzling is the ways in which these productions of “soul” and “nation” enabled unlikely political alliances between national conservative elites and the local, historically left-leaning working class protesters. The author argues that (...) “soul” is reproduced through racialized discourse signifying the spiritual and ethnic purity of whiteness, the consolidation of white ethnicity, and the spirit of white resistance, articulated through campaigns to save children from future captivity in an “alien” world. Through this on-site theoretical analysis, the author demonstrates how a right-wing narrative of victimhood facilitates the reproduction of ethnic identification among the protesters, whose whiteness apparently can be jeopardized by reading the “wrong” books.

The field of experimental philosophy has received considerable attention, essentially for producing results that seem highly counter-intuitive and at the same time question some of the fundamental methods used in philosophy. A substantial part of this attention has focused on the role of intuitions in philosophical methodology. One of the major contributions of experimental philosophy on this topic has been concrete evidence in support of intuitional diversity; the idea that intuitions vary systematically depending on variables such as ethnicity, socioeconomic background, (...) or gender. Because of the important implications, these findings have been the subject of extensive debate. Despite the seeming significance of the findings and despite all the debates that the experimental philosophy movement has prompted, what has not been examined systematically is the reproducibility of the results. Instead, the reported findings have been simply accepted as established facts. We set out to replicate a wide range of experiments and surprisingly failed to reproduce many of the reported findings, some of which are from the most cited and attention grabbing papers of the field. We draw two conclusions from our findings. The first is that the instability of intuitions has been exaggerated by experimental philosophers. Intuitions appear to be more uniform across different demographic groups. The argument that intuitions need to be discarded because they depend on arbitrary factors such as ethnicity, socioeconomic background, or gender does not seem tenable anymore. The second conclusion is that experimental philosophy needs a better system to ensure the reproducibility of published findings. The current research-publication system of various empirical fields, especially those employing statistical methods, leads to an overproduction of false-positive findings in the published literature. Unless changes are made to the current research-publication system, this overproduction is likely to continue, in experimental philosophy as well as other disciplines. (shrink)

The article addresses the production of reproducibility as a topic that has become acutely relevant in the recent discussions on the replication crisis in science. It brings the ethnomethodological stance on reproducibility into the discussions, claiming that reproducibility is necessarily produced locally, on the shop floor, with methodological guidelines serving as references to already established practices rather than their origins. The article refers to this argument empirically, analyzing how a group of novice neuroscientists performs a series of (...) measurements in a transcranial magnetic stimulation experiment. Based on ethnography and video analysis, the article traces a history of the local measurement procedure invented by the researchers in order to overcome the experimental uncertainty. The article aims to demonstrate how reproducibility of the local procedure is achieved in the shop floor work of the practitioners and how the procedure becomes normalized and questioned as incorrect in the course of experimental practice. It concludes that the difference between guidelines and practical actions is not problematic per se; what may be problematic is that researchers can be engaged in different working projects described by the same instruction.

In this commentary, we point to guidelines for performing human neuroimaging studies and their reporting in microbiota-gut-brain articles.

Purpose: This study aimed to develop a stroke effectiveness test in table tennis based on the temporal game structure to assess the ball speed and ball placement of the players, with a purpose to analyze its reproducibility and validity. Methods: Nineteen male table tennis players participated in this study. The test was performed twice during the first session and once during the second session to assess the intrasession and intersession reproducibility, respectively. Moreover, the test was examined on its (...) ability to discriminate between regional and local performance-level players and on the relationship between the test results and the table tennis performance to assess the discriminant and concurrent validity, respectively. In general, the test consisted of 11 simulated rallies of 2–5 balls with the effort and rest ratio of 0.5, and focused on attack with offensive strokes at defensive balls delivered by a robot randomly between the left and right positions on the table. Results: Ball speed, ball placement, and ball speed-ball placement index showed satisfactory reliability and agreement outcomes. Additionally, the Bland-Altman plots show the systematic error of the analyses closer to 0, and that most values were within the limits of agreements. Concerning validity analyses, regional players had higher scores of ball placement and ball speed-ball placement index as well as made fewer errors than local players. Moreover, ball placement, ball speed-ball placement index, and percentage error presented a strong and significant correlation with table tennis performance. However, ball speed was slightly different between the regional than local players and this variable was not related to table tennis performance. Conclusion: Our findings show evidences that the test is reproducible. Moreover, discriminant and concurrent validity are confirmed for ball placement and ball speed-ball placement index. (shrink)

Since 2015, the ‘refugee crisis’ is possibly the most photographed humanitarian crisis in history. Photographs taken, for instance, in Lesvos, Greece, and Bodrum, Turkey, were instrumental in generating waves of public support for, and populist opposition to “welcoming refugees” in Europe. But photographs do not circulate in a vacuum; this book explores the visual economy of the ‘refugee crisis,’ showing how the reproduction of images is structured by, and secures hierarchies of gender, sexuality, and ‘race,’ essential to the functioning of (...) bordered nation-states. Taking photography not only as the object of research, but innovating the method of photographìa— the material trace of writing/grafì with light/phos—this book urges us to view images and their reproduction critically. Part theoretical text, part visual essay, "Reproducing Refugees" vividly shows how institutional violence underpins both the spectacularity and the banality of ‘crisis.’ This book goes about synthesising visual studies with queer, feminist, postcolonial, post-structuralist, and post-Marxist theories. "Reproducing Refugees: Photographìa of a Crisis" offers theoretical frameworks and methodological tools to critically analyse representations, both those circulated through hegemonic institutions, and those generated from ‘below’. It carves a space between logos and praxis, ways of knowing and ways of doing, by offering a new visual language that problematises reified categories such as that of the ‘refugee’ and makes possible disruptive, alternative, resistant perceptions. The book contributes to the fields of migration and border studies, critically engaging visual narratives drawn from migration movements to question dominant categories and frameworks, from a decolonial, no-borders, queer feminist perspective.

In this article, we use qualitative methodology to explore how 15 low‐income women of diverse sociocultural location construct and experience health and weight gain during pregnancy, as well as how they position themselves in relation to messages pertaining to weight gain, femininity and motherhood that they encounter in their lives. Discussing the findings through a feminist poststructuralist lens, we conclude that the participants are complex, fragmented subjects, interpellated by multiple and at times conflicting subject positions. While the discourse of maternal (...) responsibility (i.e. managing personal behaviours for the baby's health) is very much in evidence in their narratives, embodied experiences of pregnancy, lived experiences of financial constraints and religious beliefs provided some with an alternative discourse and resistant subject position. Participants also had mixed emotions about weight gain; they recognized the need to gain weight in order to have a healthy pregnancy, but weight gain was also not welcome as participants reproduced the dominant discourse of obesity and the discourse of ‘feminine’ bodily norms. Based on our results, we advocate for change to recent clinical guidelines and social discourses around pregnancy and weight gain, as well as for policies that provide pregnant women with a range of health‐promoting resources.

Every day, in professional work and in our personal lives, we reproduce by words and behaviors particular understandings of life and how it works. This includes understandings about what is ‘normal’ and ‘not normal’ masculinity and who are ‘normal’ and ‘not normal’ boys and men. Being marginalized or outcast from the norm is rarely a free choice. The language that constructs normal and abnormal is not innocent and does not simply arrive in our minds transparently reflected in our behavior or (...) in our client advice or student education. Examining words and behaviors from adolescent boys and from media sources, this research explores the role of cultural discourses in producing normative and marginalized masculinities. It builds upon recent scholarship that questions cultural prescriptions for masculinity and traditional male norms. Feminist, poststructural, psychoanalytic discourse analysis and multiple methods were used to explore links between cultural discourses of masculinity and performativity of masculinity. Practices of heterosexuality, homophobia, athleticism, economic privilege, toughness, and violence provided pathways toward achieving and/or maintaining status as the hegemonic masculine norm in adolescence. ‘Popularity’ signified the norm and ‘outcasts’ from the norm signified marginalized masculinities.

Building animated conversational agents requires developing a fine-grained analysis of the motions and meanings available to interlocutors in face-to-face conversation and implementing strategies for using these motions and meanings to communicate effectively. In this paper, we describe our research on signaling uncertainty on an animated face as an end-to-end case study of this process. We sketch our efforts to characterize people’s facial displays of uncertainty in face-to-face conversation in ways that allow us to simulate those behaviors in an animated agent. (...) Our work has led to new insights into the structure, timing, expressive content and communicative function of facial actions that we must take into account to explain our empirical findings and to build agents that reproduce people’s effective use of the face in managing the dynamics of conversation.

A heated debate surrounds the significance of reproducibility as an indicator for research quality and reliability, with many commentators linking a "crisis of reproducibility" to the rise of fraudulent, careless and unreliable practices of knowledge production. Through the analysis of discourse and practices across research fields, I point out that reproducibility is not only interpreted in different ways, but also serves a variety of epistemic functions depending on the research at hand. Given such variation, I argue that (...) the uncritical pursuit of reproducibility as an overarching epistemic value is misleading and potentially damaging to scientific advancement. Requirements for reproducibility, however they are interpreted, are one of many available means to secure reliable research outcomes. Furthermore, there are cases where the focus on enhancing reproducibility turns out not to foster high-quality research. Scientific communities and Open Science advocates should learn from inferential reasoning from irreproducible data, and promote incentives for all researchers to explicitly and publicly discuss their methodological commitments, the ways in which they learn from mistakes and problems in everyday practice, and the strategies they use to choose which research component of any project needs to be preserved in the long term, and how.

Replicability and reproducibility of computational models has been somewhat understudied by “the replication movement.” In this paper, we draw on methodological studies into the replicability of psychological experiments and on the mechanistic account of explanation to analyze the functions of model replications and model reproductions in computational neuroscience. We contend that model replicability, or independent researchers' ability to obtain the same output using original code and data, and model reproducibility, or independent researchers' ability to recreate a model without (...) original code, serve different functions and fail for different reasons. This means that measures designed to improve model replicability may not enhance (and, in some cases, may actually damage) model reproducibility. We claim that although both are undesirable, low model reproducibility poses more of a threat to long-term scientific progress than low model replicability. In our opinion, low model reproducibility stems mostly from authors' omitting to provide crucial information in scientific papers and we stress that sharing all computer code and data is not a solution. Reports of computational studies should remain selective and include all and only relevant bits of code. (shrink)

In this response to Robert Hudson’s article, “Should We Strive to Make Science Bias-Free? A Philosophical Assessment of the Reproducibility Crisis,” we identify three ways in which he misrepresents our work: he conflates value-ladenness with bias; he describes our view as one in which values are the same as evidential factors; and he creates a false dichotomy between two ways that values could be considered in science for policy. We share Hudson’s concerns about promoting scientific reproducibility and reducing (...) bias in science, but we reject his view that the value-free ideal provides helpful guidance for addressing these issues.

Recent philosophical work has praised the reward structure of science, while recent empirical work has shown that many scientific results may not be reproducible. I argue that the reward structure of science incentivizes scientists to focus on speed and impact at the expense of the reproducibility of their work, thus contributing to the so-called reproducibility crisis. I use a rational choice model to identify a set of sufficient conditions for this problem to arise, and I argue that these (...) conditions plausibly apply to a wide range of research situations. Currently proposed solutions will not fully address this problem. Philosophical commentators should temper their optimism about the reward structure of science. (shrink)

Most discussions of the reproducibility crisis focus on its epistemic aspect: the fact that the scientific community fails to follow some norms of scientific investigation, which leads to high rates of irreproducibility via a high rate of false positive findings. The purpose of this paper is to argue that there is a heretofore underappreciated and understudied dimension to the reproducibility crisis in experimental psychology and neuroscience that may prove to be at least as important as the epistemic dimension. (...) This is the communication dimension. The link between communication and reproducibility is immediate: independent investigators would not be able to recreate an experiment whose design or implementation were inadequately described. I exploit evidence of a replicability and reproducibility crisis in computational science, as well as research into quality of reporting to support the claim that a widespread failure to adhere to reporting standards, especially the norm of descriptive completeness, is an important contributing factor in the current reproducibility crisis in experimental psychology and neuroscience.

Transcranial direct current stimulation (tDCS) has been recognized as a promising tool for investigating the causal relationship between specific brain areas of interest and behavior. However, the reproducibility of previous tDCS studies is often questioned because of failures in replication. This study focused on the effects of tDCS on one cognitive domain: beauty perception. To date, the modulation of beauty perception by tDCS has been shown in two studies:Cattaneo et al. (2014)andNakamura and Kawabata (2015). Here, we aimed at replicating (...) their studies and investigating the effects of tDCS on beauty perception using the following parameters: (1) cathodal stimulation over the medial prefrontal cortex (mPFC) (Nakamura and Kawabata, 2015); (2) anodal stimulation over the left dorsolateral prefrontal cortex (lDLPFC) (Cattaneo et al., 2014). We also performed a more focal stimulation targeting the orbitofrontal cortex (OFC) to determine the optimal stimulation site for modulating beauty perception (3). Participants rated the subjectively-perceived beauty of the images before and after the tDCS administration. We divided images into four clusters according to the obtained scores in our preliminary study and examined changes in beauty ratings in each image cluster separately to exclude factors, such as stimuli attributions that may reduce tDCS effects. The results showed no strong effects of tDCS with the same parameters as in previous studies on beauty rating scores in any image cluster. Likewise, anodal stimulation over the OFC did not result in a change in rating scores. In contrast to previous studies, the current study did not corroborate the effects of tDCS on beauty perception. Our findings provide evidence regarding the recent reproducibility issue of tDCS effects and suggest the possible inflation of its effects on cognitive domains. (shrink)

In the life sciences, there is an ongoing discussion about a perceived ‘reproducibility crisis’. However, it remains unclear to which extent the perceived lack of reproducibility is the consequence of issues that can be tackled and to which extent it may be the consequence of unrealistic expectations of the technical level of reproducibility. Large-scale, multi-institutional experimental replication studies are very cost- and time-intensive. This Perspective suggests an alternative, complementary approach: meta-research using sociological and philosophical methodologies to examine (...) researcher trust in data. An improved understanding of the criteria used by researchers to judge data reliability will provide crucial, initial evidence on the actual scale of the reproducibility crisis and on measures to tackle it.

In this paper, we examine the governance of fertility services and situate our analysis in the broader context of reproductive ageing. Most countries restrict access to these services in reference to the age of people (especially women) who are unable to conceive and the causes of such inability. Despite the popularity of this approach, we argue that age- and cause-based restrictions actively rely on, and hence perpetuate, the constraints that hinder the realization of reproductive aspirations. To motivate this view, we (...) provide an overview of the demographic trends that have reconfigured women’s reproductive lifecourse. We then argue that the criteria governing access to publicly funded services are anachronistic, as they alienate policy from citizens’ circumstances. In closing, we question the legitimacy of a reproductive governance that perpetuates existing inequality of opportunity, and propose the following changes: (1) de-responsibilizing (in)fertility; (2) reconsidering restrictions; (3) recognizing reproductive aspirations as a public good.

Examples from the sciences showing that mechanisms do not always succeed in producing the phenomena for which they are responsible have led some authors to conclude that the regularity requirement can be eliminated from characterizations of mechanisms. In this article, I challenge this conclusion and argue that a minimal form of regularity is inextricably embedded in examples of elucidated mechanisms that have been shown to be causally responsible for phenomena. Examples of mechanistic explanations from the sciences involve mechanisms that have (...) been shown to produce phenomena with a reproducible rate of success. By contrast, if phenomena are infrequent to the point that they amount to irreproducible observations and experimental results, they are indistinguishable from the background noise of accidental happenings. The inability to detect or measure the phenomenon of interest against the background noise of accidental correlations makes it impossible to elucidate a mechanism by experimental means, to demonstrate that a proposed mechanism actually produces the phenomenon, and ultimately to justify why a hypothetical scenario involving an irregular mechanism should be preferred over attributing irreproducible happenings to chance.

Feelings of guilt have been reported by (formerly) pregnant people, for example, after miscarriage, stillbirth, induced abortion, or preterm birth. However, it is sometimes held that they should not feel that way. In this article, the authors (a) scrutinize attributions of guilt, (b) problematize philosophical approaches to guilt—especially Thomas Scanlon’s approach—and moral emotions more broadly, and (c) criticize such theoretical-normative interventions in light of sociopolitical expectations surrounding pregnancy. They conclude that, rather than denouncing experiences of guilt in perinatal contexts as (...) “inapt” or “misplaced,” the norms and expectations that trigger and cultivate such feelings should be addressed.

The status quo on parental licensing in most Western jurisdictions is that licensing is required in the case of adoption but not in the case of assisted or unassisted biological reproduction. To have a child via adoption, one must fulfill licensing requirements, which, beyond the usual home study, can include mandatory participation in parenting classes. One is exempt from these requirements, however, if one has a child via biological reproduction, including assisted reproduction involving donor gametes or a contract pregnancy. In (...) an earlier paper, we challenged this system of parental licensing by showing that arguments in favour of it do not succeed. One argument we failed to consider, however, is that prospective biological parents have a right to reproduce that protects them against the sort of state interference that is involved in parental licensing. According to this argument, because prospective adoptive parents do not exercise a similar right when attempting to become parents, they are not similarly protected. In this paper, we argue that this reproductive rights argument, like other arguments in favour of the status quo on parental licensing, is flawed. We also question whether people in fact have a right to reproduce, and in doing so distinguish this right from others that we think are legitimate, including a right to become a parent and a right to bodily autonomy.
