Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about (...) fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

Understanding how teacher leaders are engaged in curriculum affairs is critical with the implementation of instructional decentralization. The current study adopts a qualitative approach to investigate Teaching Research Group leaders’ involvement in curriculum leadership in the Chinese context. It explores the conceptions of TRG leaders by interviewing 20 of them, observing four meetings held by TRG leaders, and collecting 10 extracts from appraisal summaries of TRG leaders in secondary schools in China. Drawing on the findings, this paper examines the (...) characteristics of TRG leader’s engagement in CL. More importantly, data highlighted significant problems the participants perceived and faced in their work as TRG leaders, which consisted of amplifying the necessity for empowering TRG leaders and identifying the phenomenon that said leaders are less empowered and less motivated to undertake the CL role. The results add to the international body of knowledge on the teachers’ engagement in CL. (shrink)

The aim of this paper is to present some important contributions to ethics, value theory and political philosophy the former members of the Bioethics Research Group have made. The group was established at the University of Copenhagen in 1992 and was formally dissolved in 1997, but the members continued to work in ethics and political philosophy and set up research groups and centres at four Danish universities. Within four research themes, contributions made over the years are (...) described. Research outputs of the group have, in various ways, served to bring studies of ethics and political philosophy originating in Denmark into the wider international research arena. Members of the group have increasingly included empirical approaches in their research and have thereby participated in the more general “empirical turn” in analytic philosophy. Some members of the group can also be said to have participated in a “pluralist turn”. (shrink)

American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) recently provided two recommendations about predictive genetic testing of children. The Clinical Sequencing Exploratory Research Consortium's Pediatrics Working Group compared these recommendations, focusing on operational and ethical issues specific to decision making for children. Content analysis of the statements addresses two issues: (1) how these recommendations characterize and analyze locus of decision making, as well as the risks and benefits of testing, and (2) whether the guidelines conflict (...) or come to different but compatible conclusions because they consider different testing scenarios. These statements differ in ethically significant ways. AAP/ACMG analyzes risks and benefits using best interests of the child and recommends that, absent ameliorative interventions available during childhood, clinicians should generally decline to order testing. Parents authorize focused tests. ACMG analyzes risks and benefits using the interests of the child and other family members and recommends that sequencing results be examined for additional variants that can lead to ameliorative interventions, regardless of age, which laboratories should report to clinicians who should contextualize the results. Parents must accept additional analysis. The ethical arguments in these statements appear to be in tension with each other. (shrink)

The Nietzsche Studies Group in Brazil is an international research group that gathers Brazilian scholars of Nietzschean philosophy and, more recently, also French and Italian researchers. Founded by Scarlett Marton in 1996, GEN was originally linked to the Philosophy Department of University of São Paulo. Having spread throughout the country, GEN continues to advance Nietzsche studies and, toward this goal, welcomes different interpretations of Nietzsche’s thought. As a pioneering initiative in South America, the Nietzsche Studies Group in Brazil intends (...) to promulgate research on Nietzsche’s thought in our own country while nonetheless remaining well connected with the different international Nietzsche...

This book investigates how collaborative scientific practice yields scientific knowledge. At a time when most of today’s scientific knowledge is created in research groups, the author reconsiders the social character of science to address the question of whether collaboratively created knowledge should be considered as collective achievement, and if so, in which sense. Combining philosophical analysis with qualitative empirical inquiry, this book provides a comparative case study of mono- and interdisciplinary research groups, offering insight into the (...) day-to-day practice of scientists. The book includes field observations and interviews with scientists to present an empirically-grounded perspective on much-debated questions concerning research groups’ division of labor, relations of epistemic dependence and trust.

This paper aims to explore disciplinary variation in valuation practices by comparing the way research groups accumulate credibility across four epistemic cultures. Our analysis is based on case studies of four high-performing research groups representing very different epistemic cultures in humanities, social sciences, geosciences and mathematics. In each case we interviewed about ten researchers, analyzed relevant documents and observed a couple of meetings. In all four cases we found a cyclical process of accumulating credibility. At the (...) same time, we found significant differences in the manifestation of the six main resources that are part of the cycle, the mechanisms of conversion between these resources, the overall structure and the average speed of the credibility cycle. The different ways in which the groups use data and produce arguments affect the whole cycle of accumulating credibility. In some cultures, journal publications are the main source of recognition, but in others one can earn significant amounts of recognition for conference contributions or service to the academic community. Moreover, the collaboration practices in the respective fields strongly influence the connection between arguments and publications. In cultures where teams of researchers collaboratively produce arguments, it is more strongly embedded in the process of writing publications. We conclude that the credibility cycle can only be used as an analytical tool to explain the behavior of researchers or research groups when taking differences across epistemic cultures into account.

There is an increased focus on fostering integrity in research by through creating an open culture where research integrity dilemmas can be discussed. We describe a pilot intervention study that used Moral Case Deliberation (MCD), a method that originated in clinical ethics support, to discuss research integrity dilemmas with researchers. Our research question was: can moral case deliberation in research groups help to navigate research integrity dilemmas? We performed 10 MCDs with 19 researchers (...) who worked in three different research groups from three different disciplinary fields at a university in the Netherlands. We analyzed the dilemmas and values discussed, sent out a survey questionnaire to assess self-perceived moral competencies, and conducted in-depth interviews. We found research integrity dilemmas pertained to authorship disputes, supervision of junior co-workers, and questionable handling of data. Participants perceived the majority of moral competencies to a higher degree during the MCD when compared to perceiving them in daily practice afterward. Interviewees told us that they felt most comfortable discussing dilemmas among peers with whom they were not closely affiliated. We conclude that MCD sessions could be relevant in navigating research integrity dilemmas, but that revisions to ensure commitment and safety are required. (shrink)

The authors study how an aerosol technology research group constructed a research agenda for itself and how its activity was changed in the process. The group's research agenda was heterogeneous, comprising several research areas in which the knowledge of aerosols was applied in different industrial contexts. The authors analyze the development of one of these areas, the research on the production of ultrafine particles from 1992 to 1997, employing the concept of mediated activity that has (...) been developed in the cultural-historical theory of activity. In the analysis, the activity is seen as the coevolution of the subject, the means, and the research object and the networks of collaboration with other activities. The applications developed in the collaborative networks significantly influence the identity and learning of the researchers, the construction of tools and instruments, and the selection of the phenomena to be studied.

This chapter describes the development of a workshop series focused on helping students develop research lab ethics guidelines. The workshop was developed through a National Science Foundation-funded project that situates ethics education within the research environment. Students in four departments at a private research university were recruited to join a Student Ethics Committee that collaboratively developed context-specific codes-of-ethics-based guidelines for their departments. These bottom-up developed guidelines were revised in an iterative process, including feedback from faculty, other graduate (...) students, and the original Student Ethics Committee. The goal of the workshops was to promote the cultivation of an ethical culture in experimental laboratories by integrating research stakeholders in a bottom-up approach to developing context-specific guidelines and to identify factors that students consider relevant to the ethical conduct of research. After describing the workshop series, this chapter presents a qualitative content analysis of the guidelines. The guidelines developed by the Student Ethics Committees reflect the current culture of experimental labs in these departments and the ethical issues that students think are important. The content of these guidelines and the ethical issues the students focused on contrast in some key ways with what ethical issues faculty who head research groups saw as paramount. The chapter describes the first two iterations of the ethics education workshop module, a qualitative analysis of the first draft of these guidelines, and finally reflects on future work in this area of in situ ethics education.

Social science research on the anthropomorphisms of computers and robots has been devoted to studying intellectual anthropomorphism, emotional anthropomorphism, bodily anthropomorphism, and the limits of computer and robot anthropomorphism. Although these represent important patterns for studying the anthropomorphisms of computers and robots, there are other important patterns. The limitation of anthropomorphism is one of these patterns. The limitation of anthropomorphism is a discursive practice which places limits on anthropomorphism. Discursive practices are interactional and practical activities for making sense of (...) who and what we encounter. In this article, I analyze the limitation of anthropomorphism as another important activity to investigate. Drawing on an ethnographic study of a robotics research group, I show the importance of the limitation of anthropomorphism by documenting how it contributes to research group identity. In the final section, I describe some implications for future studies of the anthropomorphisms of computers and robots. (shrink)

A book review of Susann Wagenknecht: A Social Epistemology of Research Groups, Palgrave, 2016.

This monograph investigates the collaborative creation of scientific knowledge in research groups. To do so, I combine philosophical analysis with a first-hand comparative case study of two research groups in experimental science. Qualitative data are gained through observation and interviews, and I combine empirical insights with existing approaches to knowledge creation in philosophy of science and social epistemology. -/- On the basis of my empirically-grounded analysis I make several conceptual contributions. I study scientific collaboration as the (...) interaction of scientists within research groups. Thereby, I argue that research groups and their role in scientific practice deserve more philosophical attention than they have hitherto received. In contemporary natural science, research groups are key to the formulation and corroboration of scientific knowledge claims prior to their publication. Specifically, I suggest epistemic difference and the porosity of social structure as two conceptual leitmotifs in the study of group collaboration. With epistemic difference, I emphasize the value of socio-cognitive heterogeneity in group collaboration. With porosity, I underline the fact that a research group as social structure does not entirely contain the inter-individual efforts necessary to formulate and corroborate knowledge claims. -/- In my analysis of research groups, I focus on the division of epistemic labor among group members. Through their complementary collaborative efforts single scientists engage in relations of mutual epistemic dependence. To deepen philosophy’s understanding of scientific practice in its diversity, a distinction should be made between opaque and translucent epistemic dependence. While opaque epistemic dependence involves asymmetries in expertise, translucent epistemic dependence does not. As epistemic dependence is facilitated by trust, I investigate the dynamics of epistemic trust in group collaboration. Trust among collaborating scientists is inherently incomplete, and I show that scientists make use of diverse strategies to increase and to supplement personal trust. Based on my reflections on trust and dependence, I give an account of the relation between individual knowing and collaboratively created knowledge in research groups. Together these investigations contribute to the discussion of philosophical methodology in the study of scientific practice and promote the use of empirical methods. (shrink)

This article contains critical reflections of a multidisciplinary research group studying the human and technological dynamics around some newly offered electronic services in a specific rural area of Finland. For their research, the group adopted ethnography. On facing the challenges of doing ethnographic research in a multidisciplinary setting, the group evolved its own breed of research practice based on multiple forms of triangulation. This implied the use of multiple data sources, methods, theories, and researchers, in different (...) combinations. One of the outcomes of the work is a model for collaborative research. It highlights, among others, the importance of creating a climate for collaboration within the research group and following a process of individual and collaborative writing to achieve the potential benefits of such research. The article also identifies a set of remaining challenges relevant to collaborative research. (shrink)

There is increasing interest in farmers’ organizations as an effective approach to farmer participatory research (FPR). Using data from an empirical study of farmers’ research groups (FRGs) in Uganda, this paper examines the patterns of participation in groups and answers questions such as: Who participates? What types of participation? How does participation occur? What are the factors determining participation? Results show that there is no single type of participation, but rather that FPR is a dynamic process (...) with types of participation varying at different stages of the process. Farmers’ participation does not follow the normal adoption curve. Rather, it is characterized by high participation at the initial stages, followed by dramatic decrease and dropping-out, and slow increases toward the end. There is usually significantly higher participation among male farmers at the beginning of the process. However, as FRGs evolve, the proportion of men decreases sharply while the relative proportion of women continues to increase until it dominates the group. The findings do not support the common assumption that groups usually exclude women and the poor. On the contrary, we argue that FRGs are an effective mechanism to provide women and the poor with opportunities to participate in research. However, to be effective, this requires moving beyond head counting to promote more proactive gender and equity perspectives for amplifying the benefits of agricultural research to those who tend to be marginalized or excluded by mainstream development initiatives. This will be critical for making agricultural research more client-oriented and demand-driven. (shrink)

ABSTRACT Genetics research, like research in sociology and anthropology, creates risks for groups from which research subjects are drawn. This paper considers what sort of protection for groups from the risks of genetics research should be provided and by whom. The paper categorizes harms by distinguishing process‐related from outcome‐related harms and by distinguishing two kinds of group harms. It argues that calls for community engagement are justified with respect to some kinds of harms, but (...) not with respect to others; and it cautions that community engagement may itself be harmful.

This article reports on a method of group mentoring to strengthen responsible research conduct. A key feature of this approach is joint exploration of the issues by trainees and their faculty research supervisors. These interactions not only help participants learn about current ethical norms for research practice, but also draw on the accumulated experience of faculty and staff about practical problems of research conduct, and help to make faculty more articulate about responsible research conduct and (...) so better able to guide their trainees. By working with departments or laboratories as a whole the method facilitates the formulation of specific norms appropriate to particular research situations and to strengthen the group’s ability to support appropriate behavior and deal with new issues as they arise. It also gives students more ways to ask questions about research practice and to benefit from the experience of all members of their department or group as well as their own research supervisors. The method is well tested and has been well received by a wide variety of departments and research groups. It provides the means for a constructive and enjoyable response to the Public Health Service’s (PHS) new Policy on Instruction in the Responsible Conduct of Research (RCR) that requires education in the responsible conduct of research for all those funded by PHS funds, including faculty and staff as well as trainees.

How are “interesting” research problems identified and made durable by academic researchers, particularly in situations defined by multiple evaluation principles? Building on two case studies of research groups working on rare diseases in academic biomedicine, we explore how group leaders arrange their groups to encompass research problems that latch onto distinct evaluation principles by dividing and combining work into “basic-oriented” and “clinical-oriented” spheres of inquiry. Following recent developments in the sociology of valuation comparing academics to (...) capitalist entrepreneurs in pursuit of varying kinds of worth, we argue that the metaphor of the portfolio is helpful in analyzing how group leaders manage these different research lines as “alternative investment options” from which they were variously hoping to capitalize. We argue portfolio development is a useful concept for exploring how group leaders fashion “entrepreneurial” practices to manage and exploit tensions between multiple matrices of valuation and conclude with suggestions for how this vocabulary can further extend analysis of epistemic capitalism within science and technology studies.

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical (...) reproductive applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.

This article considers different ways in which keywords and concepts have been, and might be, explored. It summarizes the methodological discussions of a project to analyse 'commonwealth' in the period 1450-1800. 'Commonwealth' was a part of a conceptual field of terms to do with the public good and thus serves as a case study for wider problems of approaching such keywords through a collaboration across disciplines and reflects the importance of recent attempts to provide social and literary contexts for political (...) discourse. Early modern states and their authority are now recognized to be as much socially and culturally as politically constructed, thus widening not only the essential 'context' which students of political discourse must take into account, but also requiring social historians to engage with the language of politics, the metaphors, images and genres of which scholars of literature and art likewise can illuminate. This social and cultural turn to political discourse helps the recovery of the language of vice and virtue which was so intrinsic to the deployment of keywords and concepts. The German conceptual history school is also relevant and useful in requiring us to think about how concepts were constituted and change over time, though its chronological focus needs to be extended to embrace more fully the fifteenth, sixteenth and seventeenth centuries. Finally, the article offers some pointers about how technology might be utilized to maximize the necessary collaborations that have been outlined. (shrink)

Biomedical research using data from participants’ mobile devices borrows heavily from the ethos of the “citizen science” movement, by delegating data collection and transmission to its volunteer subjects. This engagement gives volunteers the opportunity to feel like partners in the research and retain a reassuring sense of control over their participation. These virtues, in turn, give both grass-roots citizen science initiatives and institutionally sponsored mHealth studies appealing features to flag in recruiting participants from the public. But while grass-roots (...) citizen science projects are often community-based, mHealth research ultimately depends on the individuals who own and use mobile devices. This inflects the ethos of mHealth research towards a celebration of individual autonomy and empowerment, at the expense of its implications for the communities or groups to which its individual participants belong. But the prospects of group harms — and benefits — from mHealth research are as vivid as they are in other forms of data-intensive “precision health” research, and will be important to consider in the design of any studies using this approach.

One of the important determinants of development during the transition to adulthood is the undertaking of social roles characteristic of adults, also in the area of finishing formal education, which usually coincides with beginning fulltime employment. In the study discussed in this paper, it has been hypothesized that continuing full-time education above the age of 26, a phenomenon rarely observed in Poland, can be considered as an unpunctual event that may be connected with difficulties in the process of identity formation. (...) Relationships between identity dimensions and identity statuses, and age and educational context were analyzed. 693 individuals aged 19-35 took part in the study. The participants attended three types of educational institutions: full-time university studies, part-time university studies, and full-time post-secondary school. Among the students of full-time university studies predictable dependencies, also in respect of highlevels of indicators of identity crisis and a high frequency of diffused identity occurrence, were observed. Such dependencies were not found in the group of full-time post-secondary school students. (shrink)

Harms and risks to groups and third-parties can be significant in the context of research, particularly in data-centric studies involving genomic, artificial intelligence, and/or machine learning technologies. This article explores whether and how United States federal regulations should be adapted to better align with current ethical thinking and protect group interests. Three aspects of the Common Rule deserve attention and reconsideration with respect to group interests: institutional review board (IRB) assessment of the risks/benefits of research; disclosure requirements (...) in the informed consent process; and criteria for waivers of informed consent. In accordance with respect for persons and communities, investigators and IRBs should systematically consider potential group harm when designing and reviewing protocols, respectively. Research participants should be informed about any potential group harm in the consent process. We call for additional public discussion, empirical research, and normative analysis on these issues to determine the right regulatory and policy path forward. (shrink)

: Some argue that human groups have a stake in the outcome of population-genomics research and that the decision to participate in such research should therefore be subject to group permission. It is not possible, however, to obtain prior group permission, because the actual human groups under study, human demes, are unidentifiable before research begins. Moreover, they lack moral standing. If identifiable social groups with moral standing are used as proxies for demes, group approval (...) could be sought, but at the expense of unfairly exposing these surrogates to risks from which prior group approval is powerless to protect them. Unless population genomics can proceed without targeting socially defined groups, or can find other ways of protecting them, it may fall to individuals to protect the interests of the groups they care about, and to scientists to warn their subjects of the need to do so.

: This essay distinguishes between two kinds of group harms: harms to individuals in virtue of their membership in groups and harms to "structured" groups that have a continuing existence, an organization, and interests of their own. Genetic research creates risks of causing both kinds of group harms, and engagement with the groups at risk can help to mitigate those harms. The two kinds of group harms call for different kinds of group engagement.

The research climate plays a key role in fostering integrity in research. However, little is known about what constitutes a responsible research climate. We investigated academic researchers’ perceptions on this through focus group interviews. We recruited researchers from the Vrije Universiteit Amsterdam and the Amsterdam University Medical Center to participate in focus group discussions that consisted of researchers from similar academic ranks and disciplinary fields. We asked participants to reflect on the characteristics of a responsible research (...) climate, the barriers they perceived and which interventions they thought fruitful to improve the research climate. Discussions were recorded and transcribed at verbatim. We used inductive content analysis to analyse the focus group transcripts. We conducted 12 focus groups with 61 researchers in total. We identified fair evaluation, openness, sufficient time, integrity, trust and freedom to be mentioned as important characteristics of a responsible research climate. Main perceived barriers were lack of support, unfair evaluation policies, normalization of overwork and insufficient supervision of early career researchers. Possible interventions suggested by the participants centered around improving support, discussing expectations and improving the quality of supervision. Some of the elements of a responsible research climate identified by participants are reflected in national and international codes of conduct, such as trust and openness. Although it may seem hard to change the research climate, we believe that the realisation that the research climate is suboptimal should provide the impetus for change informed by researchers’ experiences and opinions.

Under what conditions is a group of scientists rational? How would rational scientists collectively agree to make their group more effective? What sorts of negotiations would occur among them and under what conditions? What effect would their final agreement have on science and society? These questions have been central to the philosophy of science for the last two decades. In this 2007 book, Husain Sarkar proposes answers to them by building on classical solutions - the skeptical view, two versions of (...) the subjectivist view, the objectivist view, and the view of Hilary Putnam. Although he finds these solutions not completely adequate, Sarkar retrieves what is of value from them and also expropriates the arguments of John Rawls and Amartya Sen, in order to weave a richer, deeper, and more developed theory of group rationality.

Lakatos’s methodology of scientific research programmes centres around series of theories, with little regard to the role of models in theory construction. Modifying it to incorporate model-groups, clusters of developmental models that are intended to become new theories, provides a description of the model dynamics within the search for physics beyond the standard model. At the moment, there is no evidence for BSM physics, despite a concerted search effort especially focused around the standard model account of electroweak symmetry (...) breaking. Using the framework provided by Lakatosian research programmes, we can capture the way the periphery of a model-group changes as the available parameter space shrinks, while its central tenets remain untouched by unfavourable experimental findings. By way of motivation, I provide two case studies of model-groups that offer alternative mechanisms for electroweak symmetry breaking: supersymmetry and composite-Higgs models. Both of these model-groups are under pressure from the discovery of the Higgs boson, yet they have both been active research projects in the years after the Higgs discovery. However, a proper assessment of the progress of an ongoing research programme is impossible through a purely Lakatosian lens, so I propose replacing it with Laudan’s problem-solving account, which provides ongoing assessment, while offering normative guidance concerning the pursuit-worthiness of research programmes. My incorporation of model-groups into Lakatosian research programmes captures the developments of two attempts to expand our physical description of the world, and Laudan’s problem-solving rationality allows us to assess their pursuit-worthiness.

In a very short time, it is likely that we will identify many of the genetic variants underlying individual differences in intelligence. We should be prepared for the possibility that these variants are not distributed identically among all geographic populations, and that this explains some of the phenotypic differences in measured intelligence among groups. However, some philosophers and scientists believe that we should refrain from conducting research that might demonstrate the (partly) genetic origin of group differences in IQ. (...) Many scholars view academic interest in this topic as inherently morally suspect or even racist. The majority of philosophers and social scientists take it for granted that all population differences in intelligence are due to environmental factors. The present paper argues that the widespread practice of ignoring or rejecting research on intelligence differences can have unintended negative consequences. Social policies predicated on environmentalist theories of group differences may fail to achieve their aims. Large swaths of academic work in both the humanities and social sciences assume the truth of environmentalism and are vulnerable to being undermined. We have failed to work through the moral implications of group differences to prepare for the possibility that they will be shown to exist. (shrink)
