The paper investigates how field experimentation of genetically modified crops became central to the French controversy on genetically modified organisms in recent years. Initially constructed in the 1980s as a cognitive endeavor to be preserved from lay interference, field trials of genetically modified crops were reconceived as “an intrusion in the social space,” which had to be negotiated with actors from that space. In order to analyze this transformation, the authors suggest that it is necessary to develop an (...) interpretive framework that combines theoretical perspectives from science and technology studies and the sociology of social problems, and emphasizes the importance of the way in which actors compete in a heterogeneous public space, to put forward alternative framings of problems. The authors present a detailed analysis of the interactions and conflicts between actors in diverse social arenas in order to better understand the dynamics of this sociotechnical controversy.

A universal basic income (UBI) would be a guaranteed income floor for both the employed and the unemployed, from which economic theory predicts a gain in bargaining power and a disincentive to work. For high earners, the increase in taxes necessary to fund this program would decrease their motivation to earn. To assess these aspects, we conducted a lab-in-the-field experiment at a State Employment Service office in Spain. The unemployed participants received either an initial unconditional endowment, framed under (...) the logic of the solidarity condition of UBI (UBI treatment) – to examine the taxes’ effect – or as a participation fee (FEE) or no initial endowment (NONUBI). Subsequently, they faced one default randomized task from a set of four paid real-effort tasks. To study bargaining power, they could change the task up to three times and/or skip all tasks and conclude the experiment. In the FEE treatment, they yielded the highest earnings. While we did not find a statistically significant difference in earnings between the FEE and the NON-UBI treatments, the UBI differed from the NON-UBI and FEE. A likely reason could be a crowding-out of motivation by the pressure to reciprocate without believing in other participants’ deservingness of the UBI. In addition, the results reveal that females change tasks more frequently than males. (shrink)

While the history and methodology of laboratory experiments in economics have been extensively studied by philosophers, those of field experiments have not attracted much attention until recently. What is the historical context in which field experiments have been advocated? And what are the methodological rationales for conducting experiments in the field as opposed to in the lab? This article addresses these questions by combining historical and methodological perspectives. In terms of history, we show that the movement toward (...) field experiments in economics has two distinct roots. One is the general orientation of medical and social sciences to evidence-based policy evaluation, which gave rise to randomized field experiments in economics. The other is an awareness of several methodological limitations of lab experiments in economics, which required practitioners to get out of the lab and into the field. In these senses, the movement is a consequence of influences from both outside and inside economics: the general evidence-based trend in policy science and an internal methodological development of experimental economics. In terms of methodology, we show that these two roots resulted in two somewhat different notions of “external validity” as methodological rationales of field experiment. Finally, we suggest that analysis of experiments as exhibits highlights a methodological strategy in which both strands complement each other. (shrink)

In May 2021, Alan Bechaz, Racher Du, Will Cailes and Thomas Spiteri interviewed Sandra Leonie Field for UPJA’s Conversations from the Region. A series of discussions that invites philosophers from or based in Australasia to share their student and academic experiences. The segment looks into what inspires people to study philosophy, how they pursue their philosophical interests, and gives our audiences a better idea of philosophy as an undergraduate.

In many experimental sciences, like particle physics or molecular biology, the proper place for establishing facts is the laboratory. In the sciences of population biology, however, the laboratory is often seen as a poor approximation of what occurs in nature. Results obtained in the field are usually more convincing. This raises special problems: it is much more difficult to obtain stable, repeatable results in the field, where environmental conditions vary out of the experimenter’s control, than in the laboratory. (...) We examine here how this problem affected an influential experimental research tradition in community ecology, the study of the ecology of the rocky seashores. In the 1960s, a handful of North-American ecologists, most notably Joseph Connell, Robert Paine and Paul Dayton, made the rocky seashores a model study system for experimenting in the field. Their experiments were deceptively simple: they removed species living on the seashore and described the resulting effects on the local ecology. These experiments exerted a deep influence on community ecology. They provided evidence for speculative developments concerning the theory of interspecific competition, the factors responsible for species richness and the ecology of food webs. They also stimulated novel conceptual developments. In particular, Paine developed the predation hypothesis, which states that the presence of predators can favour species richness, before introducing the keystone species concept, according to which some species exert disproportionate effects on ecological systems. More broadly, these experiments gave support to a methodological trend in favour of field experimentation. Only controlled perturbations in the field, it seemed, provided a reliable method to get insights into the structure of ecological communities. However, as experiments were continued in time and repeated in different sites, divergent results appeared. We analyse here how intertidal researchers coped with the variability of environmental conditions and tried to stabilize their results. In the process, they reconsidered not only their early conclusions, but also the exclusive status given to field experiments. Expanding on this case study, we discuss some significant differences between laboratory and field experiments. (shrink)

"Combining aspects of his acclaimed street work with an innovative approach to portraiture, Chicago-based photographer Jed Fielding has concentrated closely on these children's features and gestures, probing the enigmatic boundaries between surface and interior. Design, composition, and the play of light and shadow are central elements in these photographs, but the images are much more than formal experiments; they confront disability in a way that affirms life. Fielding's sightless subjects project a vitality that seems to extend beyond the limits of (...) self-consciousness. In collaborative, joyful participation with the children, he has made pictures that reveal essential gestures of absorption and the basic expressions of our creatureliness. Fielding's work achieves what only great art, and particularly great portraiture can: it launches and then complicates a process of identification across the barriers that separate us from each other.

Recent policy reports documented that a growing group of students in secondary education could perform better given their expected performance. Studies showed that school performance is related to a range of social-emotional factors, including self-awareness, self-management, social awareness and responsible decision making. However, experimental studies in schools on the relation between these factors and school performance are scarce and results are mixed. This study used a randomized field experiment to examine whether self-reflection on school behavior of underperforming secondary (...) school students affected their school performance (GPA), school engagement and self-concept. The sample comprised 337 9th grade students (M = 15.74 years old; SD = 0.58) from 18 secondary schools in the Netherlands. The intervention was designed in co-creation with teachers, to be as close to school practice as possible. Underperformance was measured using achievement test scores from both primary and secondary school, supplemented with teacher and parental assessments. Different model specifications were estimated to perform the analyses, and test for robustness of findings. The results showed that for treatment compliance, students with higher school motivation were approximately 29 percent more likely to comply. Students who reported higher levels of self-concept of school tasks were 17 percent less likely to comply. No significant effects of the treatment were observed on students’ GPA, school motivation, hours spent on homework or self-concept of school tasks. The treatment showed a negative effect on self-concept of leadership skills. (shrink)

Randomized experiments, as developed by Esther Duflo and Abhijit Banerjee at the Abdul Latif Jameel Poverty Action Lab, offer a novel, evidence-based approach to fighting poverty. This approach is original, in that it imports the methodology of clinical trials for application in development economics. This paper examines the analogy between J-PAL’s field experiments in development economics and randomized controlled trials in medicine. RCTs and randomized field experiments are commonly treated as identical, but such treatment neglects some of the (...) major distinguishing features that make each experiment specifically apt for use in its respective field. The central claim of this paper is that the analogy between medicine and development economics is incomplete because the central dimensions of RCTs are not simply different but altogether lacking in J-PAL’s approach. This weakens both the political and the theoretical power of such experiments in development economics. (shrink)

This paper discusses social mechanisms of discrimination and reviews existing field experimental designs for their identification. We first explicate two social mechanisms proposed in the literature, animus-driven and statistical discrimination, to explain differential treatment based on ascriptive characteristics. We then present common approaches to study discrimination based on observational data and laboratory experiments, discuss their strengths and weaknesses, and elaborate why unobtrusive field experiments are a promising complement. However, apart from specific methodological challenges, well-established experimental designs fail to (...) identify the mechanisms of discrimination. Consequently, we introduce a rapidly growing strand of research which actively intervenes in market activities varying costs and information for potential perpetrators to identify causal pathways of discrimination. We end with a summary of lessons learned and a discussion of challenges that lie ahead. (shrink)

In the middle of the twentieth century, physiologists interested in human biological rhythms undertook a series of field experiments in natural spaces that they believed could closely approximate conditions of biological timelessness. With the field of rhythms research was still largely on the fringes of the life sciences, natural spaces seemed to offer unique research opportunities beyond what was available to physiologists in laboratory spaces. In particular, subterranean caves and the High Arctic became archetypal ‘natural laboratories’ for the (...) study of human circadian (daily) rhythms. This paper is explores the field experiments which occurred in these ‘timeless spaces’. It considers how scientists understood these natural spaces as suitably ‘timeless’ for studying circadian rhythms and what their experimental practices can tell us about contemporary physiological notions of biological time, especially its relationship to ‘environmentality’ (Formosinho et al. in Stud History Philos Sci 91:148–158, 2022). In so doing, this paper adds to a growing literature on the interrelationship of field sites by demonstrating the ways that caves and the Arctic were connected by rhythms scientists. Finally, it will explore how the use of these particular spaces were not just scientific but also political – leveraging growing Cold War anxieties about nuclear fallout and the space race to bring greater prestige and funding to the study of circadian rhythms in its early years.

In this dissertation I offer a theory of intrinsic value based on contextualist principles drawn from the value theories of John Dewey and Alfred North Whitehead. The point of departure for the argument is the contextualist view that the qualitative patters representing in experience objects of states of affairs to which we attribute values provide necessary, but not sufficient, conditions to elicit particular valuations, and ground the evaluative judgments we make. The sufficient conditions for valuation include a broader context of (...) memories, beliefs, and peripheral qualia that combine in an integral experiential whole whose value is not reducible to that of its parts. It is first argued that value is, as G.E. Moore suggested, a simple, indefinable property. This property is emergent from experiential qualitative patterns in the sense that value is conditioned by the patterns, but is not itself a condition of them. An analysis of experiential qualitative pattern is then offered, which indicates how some parts of these patterns are focused on in evaluative judgment as crucial for the reproduction of particular values through practical action, whereas the influence of other parts is largely ignored, thus forming a relatively constant experiential context. Finally, a theory of evaluative judgment is offered based on contextualist principles. It is suggested that a contextualist theory can answer the challenge of value relativism by showing how evaluative judgment is 'position relative' rather than 'author relative'. That is, two subjects many come to different evaluative judgments on account of their differing positions or situations, while both may agree that the other's judgment is sound given his or her situation.

This dual methods study explored one social studies teacher education program as it attempted to incorporate a cycle of practice-based teacher education into a methods course for the purpose of democratizing the teacher education experience. In addition to detailing the pedagogical decisions of the course instructor, researchers followed two social studies teacher candidates into their student teaching experience. Findings suggested that promoting social studies practice through a pedagogy of enactment is not enough. Rather, mentor teachers, course instructors, and teacher candidates (...) need to be aligned pedagogically as to the purposes and practices of social studies education. (shrink)

These days many gyms and fitness centers are closed to reduce transmission of the SARS-CoV-2 virus in society. The gym is an environment rich in microorganisms, and careful hygiene is a necessity to keep infections at bay. Exercise centers strive for better hygiene compliance among their members. This effort has become essential in light of the current pandemic. Several experimental studies show that others’ physical presence, or the “illusion” of being watched, may alter behavior. This article reports on a natural (...) field experiment testing one specific social nudge intended to increase gym members’ hygienic behavior. The study was conducted before the SARS-COV-2 pandemic. A picture of “observing eyes” was attached to paper dispensers and cleanser spray bottles at two different gyms in Norway. A reversal design, also called an ABA design, with and without the nudge’s presence, was used to investigate the impact on gym members’ hygienic behavior. A follow-up study was conducted in one of the centers to investigate whether the nudge stimuli would function over time. The study included 254 individual choice situations during nine observation sessions conducted over 9 weeks. The results from both centers provide evidence of a strong effect of the nudge. However, the effect decreased during the follow-up study. These findings support previous research indicating that human behavior is influenced by the presence of implicit observation cues – in this case – observing eyes. However, insights into the long-term effect of implicit observation cues are still needed since the salience of the stimuli faded over time. (shrink)

In ‘Field Experiments and Methodological Intolerance,’ Glenn Harrison develops a criticism of randomized field experiments and denounces ‘intolerance’ for lab experiments and a ‘disconnect from theory.’ We argue that lab experiments and RCTs are based on different methodological approaches and therefore fulfill different scientific objectives; key features of the RCT methodology make it highly relevant for policy-making, which accounts for a large part of its uptake; RCTs foster a convergence of interests between policy-makers and researchers around the study (...) of economic mechanisms, which makes it possible to challenge and improve economic theory based on real-world facts; and hybrid forms of experimentation are being increasingly used and open promising avenues. In sum, economic research based on RCTs is more and more connected to theory and other forms of experiment, while also helping policy-makers tackle daunting problems of poverty and exclusion.

Two experiments are described that investigate the effects of attention in moderating evaluative conditioning (EC) effects in a picture‐picture paradigm in which previously discovered experimental artifacts (e.g., Field & Davey, 1999 Field, AP, and Davey, GCL, (1999). Reevaluating evaluative conditioning: A nonassociative explanation of conditioning effects in the visual evaluative conditioning paradigm, Journal of Experimental Psychology. Animal Behavior Processes 25 ((1999)), pp. 211–224.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) were overcome by counterbalancing conditioned stimuli (CSs) and unconditioned (...) stimuli (USs) across participants. Conditioned responses for individuals who had attention enhanced were compared against a control group and groups for whom attention was impeded using a distracter task. In a second experiment the effects of attention were dissociated from those of contingency awareness by using backward‐masked US presentations. The results of these experiments indicate that although associative EC effects may not be disrupted by a lack of contingency awareness, attention is an important factor in establishing conditioning. These results shed some light onto the possible boundary conditions that could explain past inconsistencies in obtaining EC effects in the visual paradigm. (shrink)

_Experience and Value: Essays on John Dewey and Pragmatic Naturalism _brings together twelve philosophical essays spanning the career of noted Dewey scholar, S. Morris Eames. The volume includes both critiques and interpretations of important issues in John Dewey’s value theory as well as the application of Eames’s pragmatic naturalism in addressing contemporary problems in social theory, education, and religion. The collection begins with a discussion of the underlying principles of Dewey’s pragmatic naturalism, including the concepts of nature, experience, and philosophic (...) method. Essays “Experience and Philosophical Method in John Dewey” and “Primary Experience in the Philosophy of John Dewey” develop what Eames believed to be a central theme in Dewey’s thought and provide a theoretical framework for subsequent discussion. The volume continues with specific applications of this framework in the areas of value theory, moral theory, social philosophy, and the philosophy of religion. Eames’s analysis of value exposes the connection between the immediately felt values of experience and the more sophisticated judgments of value that are the product of reflection. From this basis in moral theory, Eames considers the derivation of judgments of obligation from judgments of fact. This discussion provides a grounding for a consideration of contemporary social issues directed by naturalistic and scientific principles. In the third section, with regard to educational theory, Eames considers possible resolutions of the current dichotomy between the factual worldview of science and the humanistic worldview of the liberal arts. The comprehensive article, “Dewey’s Views of Truth, Beauty, and Goodness,” connects the essays of the first and second sections and explores the placement of Dewey’s value theory with respect to morals and aesthetics. With “Creativity and Democracy,” in the fourth section, Eames also considers the concept of democracy from the standpoint of current and historical issues faced by society. This article hints at a major project of Eames’s intellectual life—the theory of democracy. The volume concludes with a discussion of the difficulty of maintaining the values of religious experience in a scientifically and technologically sophisticated world, the very topic that first brought Eames to philosophy—the meaning of religion and the religious life. Suggested solutions are offered in “The Lost Individual and Religious Unity.” _Experience and Value: Essays on John Dewey and Pragmatic Naturalism _illuminates Eames’ life of inquiry, a life that included moral, social, aesthetic, and religious dimensions of value—all suffused with the influence of John Dewey. _ _ __.

Helen Fielding, in examining Yael Bartana’s video art works, in particular, Wild Seeds (2005), argues that politics seem to privilege the temporal, and video art thus lends itself to this enactment. Drawing upon Hannah Arendt, she concludes that the in-between, while a space and not a territory, is more a spacing, a taking place between people “no matter where they happen to be” than a place as such. In Bartana’s works, the temporal aspect of video allows her to open up (...) a time-space, or rather a spacing as a relation rather than a place. It is a spacing that takes place only when the art work sets to work in its engagement with viewers, that is, when the video is playing in a public space. Moreover, Bartana generally takes up temporally circumscribed events that are deeply embedded in the past, yet show up either disjuncture or parallels between national identity and individual embodied narratives. While national identity might rely upon fusion, Bartana’s videos upset that identity by opening up a spacing where identity can be questioned. Filming events such as a demonstration, an initiation into military weapons training, as well as play, her videos draw upon ritualized events that, in their repetition, are often meant to work performatively at a corporeal level to create a national and cultural unity. Her videos affectively and phenomenally draw the viewer into the corporeal experience of these rituals in order to show up the ruptures; indeed, they seem to suggest that it is at the level of the corporeal that this cohesion can both be effected and also undone. In other words, rather than focusing on national identity which is exclusive and hence spatial, corporeal being-with is temporal—the polis is figured as embodied intermittent relations or spacings rather than as an actual territory or space. -/- .

According to the experimental results, we are able to quantify the size and the impact of (...) three main biases that explain the anomalous behavior of participants: Bayesian updating, illusion of control and status quo bias.

Phenomenally strong artworks have the potential to anchor us in reality and to cultivate our perception. For the most part, we barely notice the world around us, as we are too often elsewhere, texting, coordinating schedules, planning ahead, navigating what needs to be done. This is the level of our age that shapes the ways we encounter things and others. In such a world it is no wonder we no longer trust our senses. But as feminists have long argued, thinking (...) grounded in embodied experience can be more open to difference; such embodied thinking helps us to resist the colonization of a singular, only seemingly neutral, perspective that closes down living potentialities.

Many in the international development community have embraced the randomized controlled field experiment, akin to a biomedical clinical trial for social interventions, as the new “gold evidential standard” in program impact evaluation. In response, critics have called upon the method’s advocates to consider the moral dimensions of randomization, leading to a debate about the method’s ethics. My research intervenes in this debate by empirically investigating how researchers manage the perception of randomization in the field. Without the possibility (...) of a placebo, researchers rhetorically and materially frame the experiment differently for the control and treatment groups. Three technologies allow for this differential framing: geographic separation, temporal delay, and public randomization ceremonies. Geographic separation is a “technology of opacity” designed to obscure unequal resource distribution by disentangling the intervention and research components of the experiment for the control group. The latter two are technologies of transparency designed to expose the element of randomization but downplay conditions that may affect participant buy in. All three technologies work to preclude collective definitions of fair resource allocation, yet they are not fully successful in preventing modes of confrontation and resistance that lie outside of the experiment’s framing.

There is good evidence that, in general, autonomic conditioning in humans occurs only when subjects can verbalize the contingencies of conditioning. However, one form of conditioning, evaluative conditioning (EC), seems exceptional in that a growing body of evidence suggests that it can occur without conscious contingency awareness. As such, EC offers a unique insight into what role contingency awareness might play in associative learning. Despite this evidence, there are reasons to doubt that evaluative conditioning can occur without conscious awareness. This (...) paper aims to critically review the EC literature and to draw some parallels to what is known about autonomic conditioning. In doing so, some important general issues about measuring contingency awareness are raised. These issues are illustrated with a brief report of an experiment in which a sensitive measure of contingency awareness is compared against a commonly used measure. (shrink)

Anecdotal evidence has long lamented the status of social studies in elementary classrooms as observed by preservice teachers. As standardized testing has risen for mathematics and language arts, social studies has been pushed aside. In the aftermath of accountability legislation such as No Child Left Behind, research indicates that social studies is less visible in elementary classrooms due to an instructional focus on tested content areas (e.g. math, language arts, reading). In this study, approximately 90 elementary preservice teachers enrolled in (...) a social studies methods course responded to a survey and indicated the frequency and quality of lessons they observed over the course of a single semester. Findings report that preservice elementary teachers witnessed few, if any, lessons in social studies in the elementary classroom. Implications for teacher education are discussed. (shrink)

Students often have difficulty connecting theoretical and text-based scholarship to the real world. When teaching in Asia, this disconnection is exacerbated by the European/American focus of many canonical texts, whereas students' own experiences are primarily Asian. However, in my discipline of political philosophy, this problem receives little recognition nor is it comprehensively addressed. In this paper, I propose that the problem must be taken seriously, and I share my own experiences with a novel pedagogical strategy which might offer a possible (...) path forward. Recent scholarship has championed an active learning approach, where students engage in their own research, and deliver outward-facing products that have a meaning and purpose beyond the confines of the student-professor relationship. In this spirit, I have put into practice a strategy of course design, where active learning is used to overcome students' disconnection with the course content. In particular, as a major component of course assessment, students are required to write an 'opinion piece', which is then showcased on a public website. The opinion piece must address a real-world issue which the student himself or herself selects and deems important; furthermore, it must build on the theoretical tools of the course and be written in a style which makes it accessible to a wider audience. I discuss the implementation of this strategy in two political philosophy courses, including strategies to avoid 'dumbing down' and ‘diluting’ the process of critical thinking. While no formal analysis of impact of the strategy on learning outcomes has been conducted, an anonymous pedagogical survey has yielded an overwhelmingly positive response for students' self-reported perceptions of the curricular innovations.

In lieu of an abstract, here is a brief excerpt of the content:Response to the CommentariesLloyd FieldsAbstractIn this response, I address three points raised in the commentaries: the question of whether there is a legitimate formal use of “moral,” the claim that a certain sort of affective capacity is required for acquiring the capacity to form other-regarding moral beliefs, and the problem of how to show that psychopaths lack the capacity to form other-regarding moral beliefs. I maintain that there is (...) a use of “moral” according to which moral beliefs need not be rational. Regarding the affective capacity that Adshead identifies, I explain that I had not intended that such a capacity be constitutive of a moral belief, even an other-regarding one. I then try a new approach, in the light of Adshead’s commentary, to the third point addressed, according to which the psychopath is unable to form other-regarding moral beliefs because a causally necessary condition for doing so is absent in him.KeywordsMoral beliefs, moral understanding, personality disorder, empathy, incapacity, responsibilityThe criticisms offered in the three excellent commentaries on my paper raise deep and important issues. I agree with many of the points made and will respond to three key issues: (1) the question of whether there is a legitimate formal use of “moral”; (2) the claim that there is a certain sort of affective capacity that is required in order to form other-regarding moral beliefs; (3) the problem of how to show that psychopaths lack the capacity to form other-regarding moral beliefs.I concede that Duff establishes (Duff 1977) that the psychopath lacks moral understanding in Duff’s own content-based sense of “moral.” It is illuminating, however, to emphasize that in my formal sense a psychopath of the kind that I consider in my paper is capable of some degree of understanding of “moral” concepts. Unlike Duff, I do not build rationality into my account of moral principles. Hence, I can accommodate eccentric, irrational or even “crazy” moral beliefs like that of Duff’s split-infinitive fanatic. A person can have irrational factual beliefs; why not irrational moral beliefs?Adshead in her commentary attributes to me the claim that moral beliefs, including other-regarding beliefs, “result” in a disposition to experience certain emotions, and to have certain attitudes in certain situations. She then writes, “it is arguable that the disposition to experience certain emotions and have certain attitudes towards others could be critical to acquiring the capacity to have other-regarding beliefs.” There is only an apparent disagreement here. First, I intended to claim that a disposition to experience certain emotions, etc., is partly constitutive of having a moral belief, not a result of having one. Second, in specifying my third condition of having a moral belief, I had in mind such attitudes and emotions as approval, disapproval, indignation and remorse. Adshead identifies an affective capacity, aspects of which are the recognition of, empathy with, and sympathy with, another’s distress. This capacity seems to correspond more or less to what Rousseau described as “natural compassion” (Rousseau [End Page 291] 1973, 66–69), which arises prior to reflection and the use of reason, and which is exemplified by a mother’s responsiveness to the distress of her child. Rousseau distinguished natural compassion from moral virtues, which require the use of reason. I agree with Adshead that having this affective capacity is likely to be critical to acquiring the capacity to have other-regarding moral beliefs.Radden’s incisive commentary poses the problem of how to show that the psychopath lacks the capacity to form other-regarding moral beliefs, since this does not follow from the fact that he fails to form them. In the light of Adshead’s commentary, I should like to try a different approach to this problem. At least one type of situation in which we say that something, x, cannot do a certain sort of thing, d, is one where a causally necessary condition for x doing d is absent. For example, we should say of a car, not simply that it does not run, but that, as it is presently constituted, it cannot run, if we found that the carburetor of its... (shrink)

A large-scale field experiment in Rotterdam, Netherlands, tested whether nudging could increase public transport use. During one work week, 4000 commuters on six bus lines, received a free travel card holder. On the three bus lines in the experimental condition, the card holders displayed a social label that branded bus passengers as sustainable travelers because of their bus use. On the three bus lines in the control condition, there was no such message on the card holders. Analysis of (...) the number of rides per hour showed that the intervention led to a change from pre-intervention to post-intervention period that was estimated to be 1.18 rides per day greater on experimental lines than on control lines. This experiment shows that public transport operators can increase public transport use by incorporating messages that positively label passengers as sustainable travelers in their communication strategies.

I show that Eric Winsberg’s principles of model-building given in Science in the Age of Computer Simulation are insufficient to argue for the external validation of simulation data in cases in which simulation results conflict, and that laboratory experiments have an advantage over simulations because conflicting experimental results can be decided between on the basis of reproducibility. I also argue that robustness of predictions serves the same function for simulations as repeatability does for laboratory experiments in either adjudicating between conflicting (...) results or allowing us to say that we do not have sufficient justification to validate the results. Finally, I argue for an interpretation of the argument from robustness that appeals to the convergence of many well-built and diverse models rather than the more common interpretation which appeals to the probability that one of a set of models is likely to be true.

Glenn Harrison [Journal of Economic Methodology, 2013, 20, 103–117] discusses four related forms of methodological intolerance with respect to field experiments: field experiments should rely on some form of randomization, should be disconnected from theory, the concept of causality should only be defined in terms of observables, and the role of laboratory experiments is dismissed. As is often the case, the cause of intolerance is ignorance, as it is here. To acquire knowledge about potential influences, which we need (...) for both the evaluation of internal and external validity of experimental results, we cannot do without theory. A purely empiricist methodology will be unable to give us sufficient understanding of the validity of these results. An account of causality only based on directly observed things, is an account based on factual influences only. This account will be too restricted, because it will not deal with the unobserved potential influences, which we need – again – for the evaluat... (shrink)

The relationship between philosophy and research on artificial intelligence (AI) has been difficult since its beginning, with mutual misunderstanding and sometimes even hostility. By contrast, we show how an approach informed by both philosophy and AI can be productive. After reviewing some popular frameworks for computation and learning, we apply the AI methodology of “build it and see” to tackle the philosophical and psychological problem of characterizing perception as distinct from sensation. Our model comprises a network of very simple, but (...) interacting agents which have binary experiences of the “yes/no”-type and communicate their experiences with each other. When does such a network refer to a single agent instead of a distributed network of entities? We apply machine learning techniques to address the following related questions: i) how can the model explain stability of compound entities, and ii) how could the model implement a single task such as perceptual inference? We thereby find consistency with previous work on “interface” strategies from perception research. While this reflects some necessary conditions for the ascription of agency, we suggest that it is not sufficient. Here, AI research, if it is intended to contribute to conceptual understanding, would benefit from issues previously raised by philosophy. We thus conclude the article with a discussion of action-selection, the role of embodiment, and consciousness to make this more explicit. We conjecture that a combination of AI research and philosophy allows general principles of mind and being to emerge from a “quasi-empirical” investigation. (shrink)

It is really impossible to say anything worth saying about Plato in general within the limits of a single article. Indeed, the more one studies Plato the more impossible does it become—if the concept of degrees of impossibility may be used in a philosophical journal. The reasons for this are manifold. The first lies in the supreme greatness of Plato as a thinker. Hardly anyone who has made a serious effort to study Plato has escaped receiving the impression of him (...) as probably the greatest thinker of all ages. The difficulty is intensified by the particular form in which his greatness is conveyed to us. One may make a distinction, a relative distinction at least, between different philosophers in this respect. With some, their message is conveyed to us with comparative rapidity, even perhaps on the first careful reading, and subsequent study adds little except in the way of detail. Among these it would perhaps not be unfair to place Hume. Others, on first reading, will appear obscure and difficult, sometimes even repellent. It is only after a much more careful study that their real greatness emerges, and they may go on increasing in stature at every subsequent reading. Such, I believe, to be the experience of the majority of readers with Kant. Plato is almost unique in that he makes his impression in both ways.

In this chapter, the author articulates two Hobbesian models of interpersonal power relations that can be used to understand gender relations: what he will call the dominion model and the deference model. Hobbes himself analyses the relation between men and women through the dominion model. The author lays out Hobbes's model of interpersonal power relations as dominion, including his application of the model to the case of gender relations. The centerpiece of Hobbes's method is his “state of nature” thought (...) class='Hi'>experiment. Hobbes's analysis is radical insofar as he understands familial relations according to the general model of interpersonal relations just outlined, without any reference to sui generis principles. The author indicates some shortcomings of the dominion model for grasping contemporary social life. The much‐celebrated social contract between equal male citizens is quietly underpinned by the sexual contract, a contract of domination between men and women. (shrink)

Costly punishment's scarcity does not belie strong reciprocity theory as Guala claims. In the presence of strong reciprocators, strategic defectors will cooperate and sanctioning will not occur. Accordingly, natural field experiments are necessary to assess a reading of costly punishment experiments. One such field experiment exists, and it supports the hypothesis that costly punishment promotes cooperation.

The concentration of high-frequency controls in a limited period of time constitutes an important feature of many law-enforcement policies around the world. In this paper, we offer a comprehensive investigation on the relative efficiency and effectiveness of various crackdown policies using a lab-in-the-field experiment with real passengers of a public transport service. We introduce a novel game, the daily public transportation game, where subjects have to decide, over many periods, whether to buy or not a ticket knowing that (...) there might be a control. Our results show that concentrated crackdowns are less effective and efficient than random controls; prolonged crackdowns reduce fare-dodging during the period of intense monitoring but induce a burst of fraud as soon as they are withdrawn; pre-announced controls induce more fraud in the periods without control. Overall, we also observe that real fare-dodgers fraud more in the experiment than non-fare-dodgers. (shrink)

Problems of cooperation have often been simplified as the choice between defection and cooperation, although in many empirical situations it is also possible to walk away from the interaction. We present the results of two lab-in-the-field experiments with a diverse pool of subjects who play optional and compulsory public goods games both with and without punishment. We find that the most important institution to foster cooperation is punishment, which is more effective in a compulsory game. In contrast to Rand (...) and Nowak (Nat Commun 2(1):1–7, 2011), we find that loners are not responsible for anti-social punishment, which is mostly imputable to low-contributors (free-riders). Loners neither totally free-ride nor they significantly punish cooperators (or other types of players): they simply avoid all forms of participation whenever possible. (shrink)

To understand how small business entrepreneurs respond to government policy one has to know their risk and time preferences. Are they risk averse, or have high discount rates, such that they are hard to motivate? We have conducted a set of field experiments in Denmark that will allow a direct characterization of small business entrepreneurs in terms of these traits. We build on experimental tasks that are well established in the literature. The results do not suggest that small business (...) entrepreneurs are more or less risk averse than the general population under the assumption of Expected Utility Theory. However, we generally find an S-shaped probability weighting function for both small business entrepreneurs and non-entrepreneurs, with entrepreneurs being more optimistic about the chance of occurrence for the best outcome in lotteries with real monetary outcomes. The results also point to a significant difference in individual discount rates between entrepreneurs and non-entrepreneurs: entrepreneurs are willing to wait longer for certain rewards than the general population.

Decompositional equivalence is the principle that there is no preferred decomposition of the universe into subsystems. It is shown here, by using a simple thought experiment, that quantum theory follows from decompositional equivalence together with Landauer’s principle. This demonstration raises within physics a question previously left to psychology: how do human—or any—observers identify or agree about what constitutes a “system of interest”?

It is really impossible to say anything worth saying about Plato in general within the limits of a single article. Indeed, the more one studies Plato the more impossible does it become—if the concept of degrees of impossibility may be used in a philosophical journal. The reasons for this are manifold. The first lies in the supreme greatness of Plato as a thinker. Hardly anyone who has made a serious effort to study Plato has escaped receiving the impression of him (...) as probably the greatest thinker of all ages. The difficulty is intensified by the particular form in which his greatness is conveyed to us. One may make a distinction, a relative distinction at least, between different philosophers in this respect. With some, their message is conveyed to us with comparative rapidity, even perhaps on the first careful reading, and subsequent study adds little except in the way of detail. Among these it would perhaps not be unfair to place Hume. Others, on first reading, will appear obscure and difficult, sometimes even repellent. It is only after a much more careful study that their real greatness emerges, and they may go on increasing in stature at every subsequent reading. Such, I believe, to be the experience of the majority of readers with Kant. Plato is almost unique in that he makes his impression in both ways. Almost everyone is captivated by him at first reading, but it is only to those who take the trouble of reading him again and again with the intellectual effort that he himself would have demanded.
