Nudges have gained popularity as a behavioral change tool that aims to facilitate the selection of the sensible choice option by altering the way choice options are presented. Although nudges are designed to facilitate these choices without interfering with people’s prior preferences, both the relation between individuals’ prior preferences and nudge effectiveness, as well as the notion that nudges ‘facilitate’ decision-making have received little empirical scrutiny. Two studies examine the hypothesis that a social proof nudge is particularly effective when people (...) have no clear prior preference, either because people are indifferent (in a colour-categorization task; Study 1, N = 255) or because people experience a choice conflict (making shopping decisions about meat products; Study 2, N = 97). Both studies employed a social proof nudge to steer participants’ choices. The potential facilitating effect of the nudge was tested using a mouse-tracker paradigm that implicitly assessed experienced uncertainty during decision-making. Results showed that the nudge was effective in steering participants’ decisions; the facilitation effect (i.e., reduced uncertainty regarding the decision) was only observed for conflicting preferences, but not under indifference. A better understanding of when and how nudges can influence individuals’ behavior may help in deciding whether nudges are an appropriate policy tool for changing particular undesirable behavior.

Dynamical systems theory (DST) is a branch of mathematics that assesses abstract or physical systems that change over time. It has a quantitative part (mathematical equations) and a related qualitative part (plotting equations in a state space). Nonlinear dynamical systems theory applies the same tools in research involving phenomena such as chaos and hysteresis. These approaches have provided different ways of investigating and understanding cognitive systems in cognitive science and neuroscience. The ‘dynamical hypothesis’ claims that cognition is and can be (...) understood as dynamical systems. Common consequences for such an approach include rejecting understanding cognition as information processing in nature, including eschewing explanatory roles for computation or representation. Contemporary applications of DST include mouse‐tracking studies in cognitive science and nonrepresentational perspectives on motor control in neuroscience. Such work has philosophical implications concerning the boundaries of cognition, explanation, and representations. DST offers powerful methodology and theories that raise many topics of philosophical significance. (shrink)

Although mouse‐tracking has been taken as a real‐time window on different aspects of human decision‐making processes, whether purely semantic information affects response conflict at the level of motor output as measured through mouse movements is still unknown. Here, across two experiments, we investigated the effects of semantic knowledge by predicting participants’ performance in a standard keyboard task and in a mouse‐tracking task through distributional semantics, a usage‐based modeling approach to meaning. In Experiment 1, participants were (...) shown word pairs and were required to perform a two‐alternative forced choice task selecting either the more abstract or the more concrete word, using standard keyboard presses. In Experiment 2, participants performed the same task, yet this time response selection was achieved by moving the computer mouse. Results showed that the involvement of semantic components in the task at hand is observable using both standard reaction times (Experiment 1) as well as using indexes extracted from mouse trajectories (Experiment 2). In particular, mouse trajectories reflected the response conflict and its temporal evolution, with a larger deviation for increasing word semantic relatedness. These findings support the validity of mouse‐tracking as a method to detect deep and implicit decision‐making features. Additionally, by demonstrating that a usage‐based model of meaning can account for the different degrees of cognitive conflict associated with task achievement, these findings testify the impact of the human semantic memory on decision‐making processes.

How people distinguish well-justified from poorly justified arguments is not well known. To study the involvement of intuitive and analytic cognitive processes, we contrasted participants’ personal beliefs with argument strength that was determined in relation to established criteria of sound argumentation. In line with previous findings indicating that people have a myside bias, participants (N = 249) made more errors on conflict than on no-conflict trials. On conflict trials, errors and correct responses were practically equal in terms of response times (...) and mouse-tracking indices of hesitation. Similarly to recent findings on formal reasoning, these findings indicate that correct reasoning about informal arguments may not necessitate corrective analytic processing. We compared findings across four argument schemes but found few differences. The findings are discussed in light of intuitive logic theories and the notion that evaluating informal arguments could be based on implicit knowledge of argument criteria. (shrink)

Researchers have recently begun to question the specificity and reliability of conflict adaptation effects, also known as sequential congruency effects, a highly cited effect in cognitive psychology. Some have even used the lack of reliability across tasks to argue against models of cognitive control that have dominated the field for decades. The present study tested the possibility that domain-general processes across tasks might appear on more sensitive mouse-tracking metrics rather than overall reaction times. The relationship between SCE effects (...) on the Stroop and Flanker tasks were examined for the first time using a mouse-tracking paradigm. Three main findings emerged: Robust SCEs were observed for both the Stroop and Flanker tasks at the group level, Within-task split-half reliabilities for the SCE across dependent variables were weak at best and non-existent in many cases, and SCEs for the Flanker and Stroop tasks did not correlate with each other for overall reaction times, but did show significant correlations between tasks on more dynamic measures that captured processes before response execution. These findings contribute to the literature by highlighting how mouse-tracking may be a fruitful avenue by which future studies can examine the specificity and reliability of conflict adaptation and tease apart different theoretical models producing the effects.

Although several theories of online syntactic processing assume the parallel activation of multiple syntactic representations, evidence supporting simultaneous activation has been inconclusive. Here, the continuous and non‐ballistic properties of computer mouse movements are exploited, by recording their streaming x, y coordinates to procure evidence regarding parallel versus serial processing. Participants heard structurally ambiguous sentences while viewing scenes with properties either supporting or not supporting the difficult modifier interpretation. The curvatures of the elicited trajectories revealed both an effect of visual (...) context and graded competition between simultaneously active syntactic representations. The results are discussed in the context of 3 major groups of theories within the domain of sentence processing. (shrink)

The greatest intensity of “live” life is captured from as close as possible in order to be borne as far as possible away. Jacques Derrida. Echographies of Television . Rainer Ganahl has made a study of studying. As part of his extensive autobiographical art practice, he documents and presents many of the ambitious educational activities he undertakes. For example, he has been videotaping hundreds of hours of solitary study that show him struggling to learn Chinese, Arabic and a host of (...) other languages. The stacked boxes of tapes are then presented like minimalist monoliths, dense archives of effort. About fifteen years ago, Ganahl began photographing the lectures that he attends. At the time, he hadn’t seen anyone else doing it, so besides his spare selection of images of the speaker and the audience, much of the time the lectures would just pass into memory, undocumented, or recorded in writing alone. Since then, he has felt the transition to digital cause a significant shift in his process. At the same time, he has seen the habit become ubiquitous as others photograph, record, and videotape the lectures all around him. In keeping with the theme of this inaugural issue of continent. , can we propose each small grouping of photographs that result an isthmus stretching between two disparate bodies of mind? The first being the body of the lecture as spelled out in the title of each work – the experience of the event in all its constituent parts. The second is the body of the recipient, the listener, in this case an artist, who plays a minimal role just beyond the prescripted behavior of sitting and listening. He uses a gesture of documentation to draw a line between himself and the event, creating an artwork. Františka + Tim Gilman: As we mentioned before, the theme of the magazine for this issue is "isthmus." It seems like a very good way into your work, and it leads us to ask what connection you see between your photographs of the lecture and the lecture itself? Rainer Ganahl: The relationship is of course a concrete, pictorial one, or if you want a mimetic one but also an abstract one because the photographs carry the title of the lecture, the names of the lecturers, the site, the institution and the time of the lecture. Photos are fixed moments of time and can reproduce images displayed and reproduce visuals presented at a moment but they don’t come with time based recordings that video or sound takes are offering. What remains of a lecture is usually just the memory, some notes and all the announcements of it. In my case I end up with a visual product I declare as my artwork. It might not differ from any snapshot taken by any other student or member of the audience but I do this in a semi-systematic way with certain rules and procedures I have set up. While I am at a lecture I am mainly focusing on the lecture itself. Last night I went to one of Slavoj Žižek which demanded quite some concentration. I even was asking him a question at the end. I took photos as well but still didn’t lose track of the lecture. I didn’t walk around, I was not preoccupied by where I was sitting and what light I was having like some of the other photographing and filming people in the room who came and left, moved around and tried to capture him from this and that angle, from close and far. I just sat there and concentrated on the lecture and yet managed to take about 30 or so images of him, the public around me and of the film clips he presented. Once the lecture is over the story changes: it all becomes a question of the images, their selection, their visual qualities, their labeling and archiving. The function of the images also change: not only do they stand for an intellectual event in a row of lectures that become part of my intellectual history within many possible such histories but they also have to function as art, something not everybody else with images of lecturers demands of their images. This is my specific claim as an artist to impose them as artworks. And as with all artistic propositions the offer can be accepted or rejected. I basically spend my life trying to do exactly that: making what I declare as art, offering something to anybody interested in it as my art, an offer that is not and will never be accepted as such by all people. F+T: What are your criteria for selection, i.e. how do you choose which lectures to photograph, by lecturer, by topic, or do you photograph any and every lecture you can? RG: As everything in my life, I go by my interest which is the result of many factors. If I am aware of a lecturer, read his books or appreciate his works my interest of attending his much higher than if I am not aware of it. I usually don’t go to lecturers simply based on their subjects—something that can happen of course, if the subject, the title of the lecture is promising or at the heart of my interest. Sometimes I also wait for years to get a change to photograph certain people but I do that in a very low-level “keep your ears up” mentality and not in a systematic scanning of all channels and possibilities. I do not go into philosophy departments and photograph everybody teaching there. I go with the flow—and unfortunately a great deal of great talks I also miss because I hear too late of them. Often, I also stumble into them by traveling, by getting emails from friends and by simply being in the right spot at the right time. Somehow you could look at my lecture par cours as some kind of loose intellectual flâneurism . If you know of interesting lectures and events, please, let me know. F+T: Is your selection of images more of a production or post-production method? That is, do you take a lot of photos and select only a few images from each lecture, or do you take them very selectively? Do you have a particular methodology for the selection of images? RG: This all changed a bit with the arrival of digital photography. In the beginning I had to pay a lot of money for film developing. Hence, I was taking either one role - 36 images - or half a role - 13 images - depending on who talked and whether they projected images. With the unlimited capacity of digital imaging I easily end up between 30 and 150 images of one event still depending of whether images are presented or not. In the first years of that project when I wasn’t fully aware yet of what I was doing, I printed at least 2 images of any lecture and sometimes three or even four, a choice that was also constrained by costs. But again, since I have a web site and since images can easily be selected and presented on my web site without generating remarkable costs I have now more and more pain to reduce them to less than ten or eight images for an event. Now, before I have them printed which really is expensive, I can present them already as artwork on my web site without any immediate costs. Thus the economic factor is at the end of the chain which enables me to be more ‘generous’ and include more images. Over the last years I have been mostly selecting at least four photographs for a lecture unit but recently also as many as ten. But so far only one set above four images has been actually printed and sold. What might sound even more shocking is the likely fact that if a curator or a collector demands me to reduce the number of images due to costs, I might compromise at this current stage if the images have not been yet printed or published outside my own web site. This means that to a certain degree any selection that has only seen publication on my web site and not yet been produced runs the risk to change in numbers of images included. Needless to say, I am the last one that finally makes a decision and I do honor all given earlier decision if those were final. F+T: How do you feel the act of photographing the lecture affects your reception of the contents of the lecture? And your recollection afterwards, do you remember the lecture more having photographed it, or just having sat and listened? RG: As mentioned above, I get very little distraction from photographing since I can multitask well and do not obsess about the quality of the image: I photograph from where I am and listen with my ears and not my eyes. I am not sure whether the images serve as a mnemonic devise to the content of the lecture if there are no images involved but they at least remind me that the lecture existed, the title of the lecture and the name of the people and institutions involved. The titles of the hundreds of lectures I took during the past 15 years can also be read as an essay of theoretical life in that period. This will be come more and more visible as time passes by. These images age much better than I do. F+T: You mentioned at the outset of our discussions that you started this practice some time ago and have seen the practice of photographing lecturers become more commonplace. Why do you think that this shift has taken place? RG: The answer is very simple. Photographing is now free of any charge and hence omnipresent. You buy a phone or any other personal digital assistant and it has a camera integrated in it whether you want it or not. There is no need to develop images and there is no hassle to keep images, to distribute images, to organize images and save them. It is all virtual, not creating any costs and doesn’t require any efforts. You don’t spend twenty dollars for photo-developing anymore, you don’t need to walk anymore to your pharmacy or your photo shop to drop off and return to pick up and pay. You don’t need to go to the post office to send somebody a picture. You have a program like Photoshop already built into your camera. Photographing is now a thing for everybody—with functioning cameras made for two year olds. It is technically now nearly impossible to make bad images. The image quality is virtually guaranteed by cheap, high performing, mini-computers packed into miniscule cameras. With all these technological changes, we are undergoing now a cultural paradigm shift that includes permanent recording (not only still image taking) of everything. I wonder even whether babies are just born to be photographed—at least a process where the first photograph is right there. What is interesting now, is how the law is trying to catch up. I am experiencing and expecting more restrictions on photographing and recording—something already in place in many museums and in certain galleries—as the recording devices become more and more invisible and undetectable. It is an interesting cat and mouse play and will end up with some of us that are photographing the world around us in court. The world has become very transparent and everybody is contributing to it with social networking technologies—like twitter and Facebook—that are designed to monitor and communicate every step we make in our lives. F+T: Why did you start the practice? As a way to remember, or to capture the experience of the lecture and the environment there? RG: A couple of years earlier I started to photograph my own reading seminars as part of my art work with results that surprised me positively. I really liked these images of students and people discussing heavy non-fiction with me. The reading seminars justified this kind of pictorialism. Then in 1995 I had the chance to attend an entire seminar by Edward Said entitled “The Representation of Intellectuals at Columbia University,” which really gave me the idea to start this series. Why not also photograph these lectures I visit all the time since this really is a way of representing intellectuals? F+T: The constellation of images and the title seem like a kind of portrait, do you agree? If so, is it a portrait of the speaker, of yourself, or of the event? RG: Well, to follow up on the previous question the lectures are more than just portraits of lecturers since I include not only the speakers but also the audience, an audience that is not named or specifically highlighted as is the speaker. So if we stick with the metaphor of the portrait we would have to extend it also to the environment, the class room, the lecture hall, the arrangements of seats or benches, tables, lecture stands and other stuff typically seen on my images. Often the walls are decorated or even tagged with graffiti or posters and other stuff. There is a big difference between a small seminar room at the English Department of Columbia University, full with books and cabinets and a lecture room at a Paris or Frankfurt university that accommodates 50 to 150 people. We should, maybe, also distinguish between lectures that are one time events—mostly open to the public, free of charge or paid—and events that are weekly, closed to the public and held mostly in universities that can cost fortunes or be paid by the State as it is still predominantly the case in continental Europe. All this, of course, is not necessarily announced in the title of the lecture and is subject to information that isn’t visible on the images. To a certain degree we see also portraits of a general privilege when it comes to the public of certain institutions that are highly selective and extremely costly without forgetting that most of the lectures are dealing with theory, art, philosophy and other highbrow subjects. In general, I would say we see very little if we don’t know already what’s going on, who the lecturer, the institutions, the context are in which we subsequently can zoom into variants like sexual, racial, or age-related make-up without ignoring clothing fashions, hair styling, body mannerisms, gadgets and stuff. F+T: Do you see a relation between this body of work and your other work, for example your language studies? RG: Everything I do is “unfortunately” related. I say unfortunately because this makes my work not so easy to grasp. The relationship to the language studies is relatively clear since both are originally grounded in the domain of education and knowledge production. Nearly all my work comes across that nexus where knowledge and power are addressed. I was at one point wondering what the relationship was to some of my earlier indexical work where I was happy alone with footnotes from books painted on the walls: I came to understand that both are just different manifestations of knowledge and information. F+T: Do you foresee continuing the series indefinitely, or is there an end to it? RG: I think that I will continue this series indefinitely or to be more precise, as long as I go listen to lectures and want to learn something which brings me to your previous question: What do the reading seminars, language studies, historical research and lecture hopping have in common: I learn something.

Mouse tracking, a new action‐based measure of behavior, has advanced theories of decision making with the notion that cognitive and social decision making is fundamentally dynamic. Implicit in this theory is that people's decision strategies, such as discounting delayed rewards, are stable over task design and that mouse trajectory features correspond to specific segments of decision making. By applying the hierarchical drift diffusion model and the Bayesian delay discounting model, we tested these assumptions. Specifically, we investigated the (...) extent to which the “mouse‐tracking” design of decision‐making tasks (delay discounting task, DDT and stop‐signal task, SST) deviate from the standard “keypress” design of decision making tasks. We found remarkable agreement in delay discounting rates (intertemporal impatience) obtained in the keypress and mouse‐tracking versions of DDT (ρ = 0.90) even though these tasks were given about 1 week apart. Rates of evidence accumulation converged well in the two versions (DDT, ρ =.86; SST, ρ =.55). Omission/commission error in SST showed high agreement (ρ =.42, ρ =.53). Mouse‐motion features such as maximum velocity and AUC (area under the curve) correlated well with nondecision time (ρ = −.42) and boundary separation (ρ =.44)—the amount of information needed to accumulate prior to making a response. These results indicate that the response time (RT) and motion‐based decision tasks converge well at a fundamental level, and that mouse‐tracking features such as AUC and maximum velocity do indicate the degree of decision conflict and impulsivity.

The primary focus of agricultural research and extension in eastern Africa is technology generation and dissemination. Despite prior critiques of the shortcomings of this approach, the consequences of such activities continue to be measured through the number of technologies developed and introduced into the supply chain. At best, impact is assessed by the total numbers of adopters and by the household and system factors influencing adoption. While the diffusion research tradition has made substantive advances in recent decades, attention to what (...) happens to technologies after adaptive, on-farm research trials continues to be limited in practice. While a host of newer approaches designed to correct for past shortcomings in diffusion research is now available, integrative methodologies that capitalize on the strengths of these different traditions are sorely needed. This article presents a more encompassing methodology for tracking the fate of technological interventions, illustrating the potential applications of findings for enhancing the positive impact of agricultural research and extension in the region.

Developmental systems theory posits that development cannot be segmented by influences acting in isolation, but should be studied through a scientific lens that highlights the complex interactions between these forces over time ( Overton, 2013a ). This poses a unique challenge for developmental psychologists studying complex processes like language development. In this paper, we advocate for the combining of highly sophisticated data collection technologies in an effort to move toward a more systemic approach to studying language development. We investigate the (...) efficiency and appropriateness of combining eye-tracking technology and the LENA (Language Environment Analysis) system, an automated language analysis tool, in an effort to explore the relation between language processing in early development, and external dynamic influences like parent and educator language input in the home and school environments. Eye-tracking allows us to study language processing via eye movement analysis; these eye movements have been linked to both conscious and unconscious cognitive processing, and thus provide one means of evaluating cognitive processes underlying language development that does not require the use of subjective parent reports or checklists. The LENA system, on the other hand, provides automated language output that describes a child’s language-rich environment. In combination, these technologies provide critical information not only about a child’s language processing abilities but also about the complexity of the child’s language environment. Thus, when used in conjunction these technologies allow researchers to explore the nature of interacting systems involved in language development. (shrink)

Three online mouse cursor-tracking experiments investigated predictive sentence processing at speed. Participants viewed visual arrays with objects like a bike and kite while hearing predictive sentences like, “What the man will ride, which is shown on this page, is the bike,” or non-predictive sentences like, “What the man will spot, which is shown on this page, is the bike.” Based on the selectional restrictions of “ride” (i.e., vs. “spot”), participants made mouse cursor movements to the bike before (...) hearing the noun “bike.” Compellingly, this effect was observed at speech rates of ∼3 (Experiment 1), ∼6 (Experiment 2), and ∼9 (Experiment 3) syllables/s. While prior research suggests striking limits on prediction, these results highlight temporal dynamics that may impact comprehenders’ ability to preactivate information when hearing impressively rapid speech. Implications for theories of sentence processing are discussed. (shrink)

In biomedical measurement, biomarkers are used to achieve reliable prediction of, and useful causal information about patient outcomes while minimizing complexity of measurement, resources, and invasiveness.

Our aim is to present a systematic methodology for assessing the reliability of multiple surrogate markers (and biomarkers in general). To do this we draw upon the robustness analysis literature in the philosophy of science and the empirical use of clinical biomarkers. -/- After introducing robustness analysis we present two problems with biomarkers in relation to reliability. Next, we propose an intervention-based robustness methodology for organizing the reliability of biomarkers in general.

The ability to sequence thoughts and actions is impaired in Parkinson’s disease. In PD, a distinct error pattern has been found in the offline performance of sequential working memory. This study examined how PD’s performance of sequential working memory unfolds over time using mouse tracking techniques. Non-demented patients with mild PD and healthy controls completed a computerized digit ordering task with a computer mouse. We measured response dynamics in terms of the initiation time, ordering time, movement time, (...) and area under the movement trajectory curve. This approach allowed us to distinguish between the cognitive processes related to sequence processing before the actual movement and the execution processes of the actual movement. PD patients showed longer initiation times, longer movement times, and more constrained movement trajectories than healthy controls. The initiation time and ordering time negatively correlated with the daily exposure to levodopa and D2/3 receptor agonists, respectively. The movement time positively correlated with the severity of motor symptoms. We demonstrated an altered temporal profile of sequential working memory in PD. Stimulating D1 and D2/3 receptors might speed up the maintenance and manipulation of sequences, respectively. (shrink)

ABSTRACTWe tested the response dynamics of the evaluative priming effect using a mouse tracking procedure that records hand movements during the execution of categorisation tasks. In Experiment 1, when participants performed the evaluative categorisation task but not the non-evaluative semantic categorisation task, their mouse trajectories for evaluatively incongruent trials curved more toward the opposite response than those for evaluatively congruent trials, indicating the emergence of evaluative priming effects based on response competition. In Experiment 2, implementing a task-switching (...) procedure in which evaluative and non-evaluative categorisation tasks were intermixed, we obtained reliable evaluative priming effects in the non-evaluative semantic categorisation task as well as in the evaluative categorisation task when participants assigned attention to the evaluative stimulus dime...

Six essential genes located near the mouse albino locus have been identified as required during specific periods of development. Amongst these six, each is required either during the preimplantation stages of development, at specific times during gastrulation, within 12 hrs after birth or during juvenile development. These genes were identified as a result of extensive genetic complementation analysis using embryos homozygous for the albino deletions. Although, in principal, the associated developmental abnormalities could result from loss of multiple genes, the (...) deletion phenotype in one case is identical to that induced by chemical mutagenesis. These results indicate that the abnormalities observed in deletion homozygotes may result from single gene loss. The deletions have proven useful not only as genetic tools to localize the position of the genes, but also as molecular entry points to the regions containing these genes. The current methodology being used to isolate candidate genes from the albino region is also reviewed here. (shrink)

Tracking technology has been heralded as transformative for animal ecology. In this paper I examine what changes are taking place, showing how current animal movement research is a field ripe for philosophical investigation. I focus first on how the devices alter the limitations and biases of traditional field observation, making observation of animal movement and behaviour possible in more detail, for more varied species, and under a broader variety of conditions, as well as restricting the influence of human presence (...) and observer bias. I reconstruct these as shifts in scope, objectivity, accuracy and fruitfulness. The second transformation is slightly less obvious but equally significant for animal ecology. Tracking devices generate complex data that demands both statistical and biological expertise, which has led to increasingly frequent and intensive collaborations between statisticians and biologists. Based on interviews, I examine how researchers in these interdisciplinary collaborations negotiate the collection, analysis and interpretation of movement data, integrating research interests, methodological constraints, previous field observations, and background theory. Tracking technology is therefore also shifting which disciplinary considerations are brought to bear on research into animal movement and behaviour and how this research is conducted. (shrink)

Methodological individualism has a long, successful, and controversial track record in the social sciences. Its record in ecology is much shorter but proving as successful and controversial with so-called individual-based models. Distinctions and debates about methodological individualism in social sciences clarify the commitments of this general, individualistic approach to modeling ecological phenomena and show that there is a lot recommending it. In particular, a representational priority on individual organisms yields a cogent albeit deflationary account of ecological emergence and helps reveal (...) how quite disparate models and theories in ecology might be unified.

Multimodal Critical Discourse Analysis (MCDA) as a sub-discipline of Critical Discourse Analysis (CDA) emerged from the availability of social semiotic frameworks describing multimodal meaning making. However, weaknesses of these frameworks have raised concerns and prompted recent methodological reflections in MCDA. Inspired by these reflections, this paper critically assesses MCDA research on advertising persuasion and identifies a lack of attention in studies to account for the social and ideological impact of advertising. This shortcoming is argued to be attributable to the weak (...) empirical grounding of social semiotic frameworks which in turn is rooted in a ‘discursive gap’ (Bateman, Citation2019, p. 300) in multimodality as a discipline. The authors then propose methodological solutions involving eye tracking experiments and higher order data analytics which can strengthen the empirical basis of theoretical assumptions made in MCDA research on advertising. Drawing on methodological guidance for empirical multimodal research, the authors discuss specific issues in realizing this proposal, focusing on a strategy addressing operationalization challenges in experimental design and the affordance of a data cluster algorithm that calculates the common viewing path of a group of viewers.

Intonation plays an integral role in comprehending spoken language. Listeners can rapidly integrate intonational information to predictively map a given pitch accent onto the speaker's likely referential intentions. We use mouse tracking to investigate two questions: (a) how listeners draw predictive inferences based on information from intonation? and (b) how listeners adapt their online interpretation of intonational cues when these are reliable or unreliable? We formulate a novel Bayesian model of rational predictive cue integration and explore predictions derived (...) under a concrete linking hypothesis relating a quantitative notion of evidential strength of a cue to the moment in time, relative to the unfolding speech signal, at which mouse trajectories turn towards the eventually selected option. In order to capture rational belief updates after concrete observations of a speaker's behavior, we formulate and explore an extension of this model that includes the listener's hierarchical beliefs about the speaker's likely production behavior. Our results are compatible with the assumption that listeners rapidly and rationally integrate all available intonational information, that they expect reliable intonational information initially, and that they adapt these initial expectations gradually during exposition to unreliable input.

Recent work on the application of neural networks to language modeling has shown that models based on certain neural architectures can capture syntactic information from utterances and sentences even when not given an explicitly syntactic objective. We examine whether a fully data-driven model of language development that uses a recurrent neural network encoder for utterances can track how child language utterances change over the course of language development in a way that is comparable to what is achieved using established language (...) assessment metrics that use language-specific information carefully designed by experts. Given only transcripts of child language utterances from the CHILDES Database and no pre-specified information about language, our model captures not just the structural characteristics of child language utterances, but how these structures reflect language development over time. We establish an evaluation methodology with which we can examine how well our model tracks language development compared to three known approaches: Mean Length of Utterance, the Developmental Sentence Score, and the Index of Productive Syntax. We discuss the applicability of our model to data-driven assessment of child language development, including how a fully data-driven approach supports the possibility of increased research in multilingual and cross-lingual issues.

When people are asked to estimate the probabilities of uncertain events, they often neglect the additivity principle, which requires that the probabilities assigned to an exhaustive set of outcomes should add up to 100%. Previous studies indicate that additivity neglect is dependent on response format, self-generated probability estimates being more coherent than estimates on rating scales. The present study made use of eye-tracking methodology, recording the movement, frequency and duration of fixations during the solution of ten additivity problems (...) and two control tasks. Participants produced more non-additive estimates in the Scale format than in the Self-generated format. Self-generated estimates also led to longer decision time and a higher number of repeated inspections, suggesting a deliberate comparison process. In contrast, the Scale format seemed to encourage a case-based approach where each outcome is evaluated in isolation. (shrink)

Until recently, experimental philosophy has been associated with the questionnaire-based study of intuitions; however, experimental philosophers now adapt a wide range of empirical methods for new philosophical purposes. New methods include paradigms for behavioural experiments from across the social sciences as well as computational methods from the digital humanities that can process large bodies of text and evidence. This book offers an accessible overview of these exciting innovations. The volume brings together established and emerging research leaders from several areas of (...) experimental philosophy to explore how new empirical methods can contribute to philosophical debates. Each chapter presents one or several methods new to experimental philosophy, demonstrating their application in a key area of philosophy and discussing their strengths and limitations. Methods covered include eye tracking, virtual reality technology, neuroimaging, statistical learning, and experimental economics as well as corpus linguistics, visualisation techniques and data and text mining. The volume explores their use in moral philosophy and moral psychology, epistemology, philosophy of science, metaphysics, philosophy of language, philosophy of mind and the history of ideas. Methodological Advances in Experimental Philosophy is essential reading for undergraduates, graduate students and researchers working in experimental philosophy. (shrink)

Measuring the rate at which the universe expands at a given time–the ‘Hubble constant’– has been a topic of controversy since the first measure of its expansion by Edwin Hubble in the 1920s. As early as the 1970s, Sandage and de Vaucouleurs have been arguing about the adequate methodology for such a measurement. Should astronomers focus only on their best indicators, e.g., the Cepheids, and improve the precision of this measurement based on a unique object to the best possible? (...) Or should they “spread the risks”, i.e., multiply the indicators and methodologies before averaging over their results? Is a robust agreement across several uncertain measures, as is currently argued to defend the existence of a ‘Hubble crisis’ more telling than a single 1% precision measurement? This controversy, I argue, stems from a misconception of what managing the uncertainties associated with such experimental measurements require. Astrophysical measurements, such as the measure of the Hubble constant, require a methodology that permits both to reduce the known uncertainties and to track the unknown unknowns. Based on the lessons drawn from the so-called Hubble crisis, I sketch a methodological guide for identifying, quantifying and reducing uncertainties in astrophysical measurements, hoping that such a guide can not only help to re-frame the current Hubble tension, but serve as a starting point for future fruitful discussions between astrophysicists, astronomers and philosophers.

Information about the powers and abilities of acting entities is used to coordinate their actions in societies, either physical or digital. Yet, the commonsensical meaning of an acting entity being deemed able to do something is still missing from the existing specification languages for the web or for multi-agent systems. We advance a general purpose abstract logical account of evidence-based ability. A basic model can be thought of as the ongoing trace of a multi-agent system. Every state records systemic confirmations (...) and disconfirmations of whether an acting entity is able to bring about something. Qualitative inductive reasoning is then used in order to infer what acting entities are deemed able to bring about in the multi-agent system. A temporalised modal language is used to talk about deemed ability, actual agency, and confirmation and disconfirmation of deemed ability. What constitutes a confirmation and a disconfirmation is left to the modeller as in general it depends on the application at hand. So to illustrate the methodology we propose two extended examples, one in practical philosophy, the other in system engineering. We first use a logic of agency and ability to obtain a version of Mele’s general practical abilities. Then, we look at the management of abilities in a supervised system. (shrink)

Parallel language activation in bilinguals leads to competition between languages. Experience managing this interference may aid novel language learning by improving the ability to suppress competition from known languages. To investigate the effect of bilingualism on the ability to control native-language interference, monolinguals and bilinguals were taught an artificial language designed to elicit between-language competition. Partial activation of interlingual competitors was assessed with eye-tracking and mouse-tracking during a word recognition task in the novel language. Eye-tracking results (...) showed that monolinguals looked at competitors more than bilinguals, and for a longer duration of time. Mouse-tracking results showed that monolinguals’ mouse movements were attracted to native-language competitors, whereas bilinguals overcame competitor interference by increasing the activation of target items. Results suggest that bilinguals manage cross-linguistic interference more effectively than monolinguals. We conclude that language interference can affect lexical retrieval, but bilingualism may reduce this interference by facilitating access to a newly learned language. (shrink)

Abstract. The paper argues for the following points: (1) Marmor's own understanding of "legal positivism" is different from the understanding defended, e.g., by Herbert Hart and Norberto Bobbio, and apparently misleads him into the wrong track of a theoretical inversion; (2) Marmor's two-stages model of (legal) interpretation—the understanding-interpretion model—provides no support for Marmor's own positivistic theory of law; (3) Marmor's concept of interpretation is at odds both with the basic tenets of Hartian and Continental methodological legal positivism, on the one (...) hand, and with the actual practice of legal interpretation in the Western world, on the other hand; (4) Marmor's concept of an easy case is likewise objectionable.

Thirty years after the publication of Thomas Kuhn’s The Structure of Scientific Revolutions, sharp disagreement persists concerning the implications of Kuhn’s "historicist" challenge to empiricism. I discuss the historicist movement over the past thirty years, and the extent to which the discourse between two branches of the historical school has been influenced by tacit assumptions shared with Rudolf Carnap’s empiricism. I begin with an examination of Carnap’s logicism --his logic of science-- and his 1960 correspondence with Kuhn. I focus on (...) problems in the analysis applied to the unit of metascientific study or appraisal, arguing for a reassessment of historicist treatment of the internal/external distinction and historiographic meta-methodology. The critique of objectivism and relativism that eventuates from this re-assessment is a double-edged blade, undercutting both objectivist and relativist treatments of cognitive evaluation and scientific change. I use it to cut across an otherwise diverse group of historicist-influenced writers, including Imre Lakatos, Larry Laudan, H. M. Collins, Stephen Stich. I. Introduction.. (shrink)

The study of eye movements is a common way to non-invasively understand and analyze human behavior. However, eye-tracking techniques are very hard to scale, and require expensive equipment and extensive expertise. In the context of web browsing, these issues could be overcome by studying the link between the eye and the computer mouse. Here, we propose new analysis methods, and a more advanced characterization of this link. To this end, we recorded the eye, mouse, and scroll movements (...) of 151 participants exploring 18 dynamic web pages while performing free viewing and visual search tasks for 20 s. The data revealed significant differences of eye, mouse, and scroll parameters over time which stabilize at the end of exploration. This suggests the existence of a task-independent relationship between eye, mouse, and scroll parameters, which are characterized by two distinct patterns: one common pattern for movement parameters and a second for dwelling/fixation parameters. Within these patterns, mouse and eye movements remained consistent with each other, while the scrolling behaved the opposite way. (shrink)

This article examines viability of track II and III initiatives between India and Pakistan and their contribution in creating a cordial environment for track I diplomacy. The objective is the probe whether informal dialogues pave the way for states to communicate formally or their presence is cosmetic in nature. Pakistan and India share a belligerent history of bilateral relationships. Despite four wars, diplomacy has somehow remained at work between the two. Although the two countries have been engaged in official and (...) backdoor dialogues periodically, however, this diplomatic contact appeared fragile and felt prey of severity many times. Track II and Track III diplomacy initiatives were launched and sought as means to reach the end of cordiality in bilateral relationships. The methodology used in this article is qualitative with primary and secondary sources. Through analysis of semi-governmental and people to people initiative, it is found that unofficial contact between the two states has not contributed toward paving the way for track I diplomacy. Such initiatives enjoy at length in good times more, rather than converting hostility into harmony in tense times. From Neemrana Dialogue to Ashoka Theater, track II and track III were unable to substitute track I. (shrink)

In public health research, tracking folk racial categories (in disease risk, etc.) is a double-edged tool. On the one hand, tracking folk racial categories is dangerous because it reinforces a problematic but fairly common belief in biological race essentialism. On the other hand, ignoring racial categories also runs the risk of ignoring very real biological phenomena in which marginalized communities, likely in virtue of their marginalization, are sicker and in need of improved resources. Much of the conversation among (...) epidemiologists and philosophers of medicine concerning the issue of tracking folk racial categories in public health research springs forth from largely black/white binarized health inequities. While health inequities between black and white Americans are certainly a very important topic, I am interested in investigating the complications to this conversation about the potential harms of tracking folk racial categories in public health research generated by the consideration of Indigenous identities in the US—groups whose health inequities are typically tracked based on the folk racial category of “Native American” or “American Indian,” but whose unique identity categories and community membership problematize the current spectrum of approaches to tracking folk racial categories in epidemiologic research. This paper will draw on scholarship by and about Indigenous people in the US context to address an undertheorized facet of the conversations concerning the potential harms of tracking folk racial categories in public health research, including the potential undermining of American Indian sovereignty and Indigenous epistemologies. I will end on some methodological considerations inspired by the inclusion of Indigenous identities in the US in the conversation about tracking folk racial categories in epidemiologic research.

Fitness apps on mobile devices are gaining popularity, as more people are engaging in self-tracking activities to record their status of fitness and exercise routines. These technologies also evolved from simply recording steps and offering exercise suggestions to an integrated lifestyle guide for physical wellbeing, thus exemplify a new era of "quantified self" in the context of health as individual responsibility. There is a considerable amount of literature in science, technology and society (STS) studies looking at this phenomenon from (...) different perspectives, linking it with the sociology of self-surveillance and neoliberal regimes of health. However, the human-technology interface, through which the micro- (behavioral) and macro- (social) aspects converge, still calls for extensive examination. This paper approaches this topic from the postphenomenological perspective, in combination with empirical studies of design analysis and interviews of fitness apps, to reveal the human-technology link between the design elements and people's perception through the direct experiences and interpretations of technology. It argues that the intentionality of self-tracking fitness app designs mediates the human-technology relations by "guiding" people into a quantified knowledge regime. It shapes the perceptions of fitness and health with representations of meanings about a "good life" of individual success and management. This paper also gives a critique of current individual, performance-oriented fitness app designs and offers the possibility of seeking alternatives through the multistable nature of human-technology relations—how altering interpretation and meaning of the design with a cultural or social context could change the form of technological embodiment.

Purpose This paper aims to fill this gap by providing a conceptual framework for discussing “technologies of the self and other,” by showing that, in most cases, self-tracking also involves other-tracking. Design/methodology/approach In so doing, we draw upon Foucault’s “technologies of the self” and present-day literature on self-tracking technologies. We elaborate on two cases and practical domains to illustrate and discuss this mutual process: first, the quantified workplace; and second, quantification by wearables in a non-clinical and (...) self-initiated context. Findings The main conclusion is that these shapings are never neutral and have ethical implications, such as regarding “quantified otherness,” a notion we propose to point at the risk that the other could become an object of examination and competition. Originality/value Although there is ample literature on the quantified self, considerably less attention is given to how the relation with the other is being shaped by self-tracking technologies that allow data sharing.

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly support (...) RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and expertise, has been misconstrued at (...) times. (2) Questions of expertise and methodology could be separated more clearly. (3) The study of expertise may be important in its own right; however, there may be good reasons to give priority to methodological concerns. (4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project. (shrink)

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a process (...) of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’.

ABSTRACTSocial attentional biases are a core component of social anxiety disorder, but research has not yet determined their direction due to methodological limitations. Here we present preliminary findings from a novel, dynamic eye-tracking paradigm allowing spatial–temporal measurement of attention and gaze-following, a mechanism previously unexplored in social anxiety. 105 participants took part, with those high and low in social anxiety traits entered into the analyses. Participants watched a video of an emotionally-neutral social scene, where two actors periodically shifted their (...) gaze towards the periphery. HSA participants looked more at the actors’ faces during the initial 2s than the LSA group but there were no group differences in proportion of first fixations to the face or latency to first fixate the face, although HSA individuals’ first fixations to the face were shorter. No further differences in eye movements were found, nor in gaze-following beha... (shrink)

The visual behaviour of consumers buying products in a supermarket was measured and used to analyse the stages of their decision process. Traditionally metrics used to trace decision-making processes are difficult to use in natural environments that often contain many options and unstructured information. Unlike previous attempts in this direction, our methodology reveals differences between a decision-making task and a search task. In particular the second stage of a decision task contains more re-dwells than the second stage of a (...) comparable search task. This study addresses the growing concern of taking eye movement research from the laboratory into the ‘real-world’, so findings can be better generalised to natural situations. (shrink)

Digital parenting tools, such as child-tracking technologies, play an ever-increasing role in contemporary child rearing. To explore opinions and experiences related to the use of such tracking devices, we conducted Q methodology and a semi-structured individual interview-study with Estonian parents and their 8- to 13-year-old pre-teens. Our aim was to study how such caring dataveillance was rationalized within the families, and to explore the dominant parenting values associated with the practice. Relying upon communication privacy management theory, the (...) issues of privacy related to such intimate surveillance were also studied. Three factors relating to the use of tracking technologies were extracted from both parents and pre-teens. Tracking technologies were viewed as parental aids that made it possible to ease anxieties and provide assurance to parents and children alike. Although children did not associate the use of tracking technologies with intrusion on privacy, they expected to have a chance to coordinate their privacy boundaries. (shrink)

Purpose This paper explores and identifies customer-value-related sacrifices that consumers attach to interactive health/life insurance. This paper aims to increase understanding of why individual consumers are not willing to embrace behaviour-tracking-based insurance applications. Design/methodology/approach The authors analysed data from a qualitative survey of Finnish insurance consumers who were not keen on adopting interactive insurance products. Findings Developed through thematic analysis, the framework presented in this paper illustrates consumers’ value sacrifices on four dimensions: economic, functional, emotional and symbolic value. (...) Research limitations/implications The framework and insights emerging in the study hold several implications related to increased understanding of consumers’ perceptions of insurance and to developing interactive insurance services. In addition, this work provides a promising foundation and avenues for further considerations related to digital ethics in insurance. Originality/value To the best of the authors’ knowledge, this paper is the first piece applying a value sacrifice perspective in studying consumers’ unwillingness to adopt interactive insurance products.

The article focuses on process management in public administration using the specific case study of the statutory city of Ostrava. Based on the selected part of the PAPRIS methodology, the process management is verified, and conclusions from the application of information system e-SMO are generalized. Ostrava is third the biggest city in Czech Republic with approximately 320 thousand citizen. Article describes experiences with SW implements, which are used for model of process in public administration. Particulary at local authority of (...) Ostrava town. Model of process is a basis for reengineering of process in state administration and preparation for implementation of big information systems. Mapping of process is providing implement and confirmation methodology to identify existing processes. Problem with its using consist in that, senior manager don’t informs, what organization is determination by processes. If are not described in given to organization current processes, or how would have had look new optimum processes, will not endeavour about reengineering successful. Procedural analysis namely offer tool and check methodology to identification current suit and it is possible him use either as instruction for reengineering function handling administrative and self-rule activities. Purpose of the article: The PAPRIS methodology was used when defining the objectives for implementation of the information system for public administration. This methodology has been elaborated by one of the authors and published in a very general scheme when solving many case studies,,. We assume that the PAPRIS is primarily a methodology with incorporated elements of procedural approach for project management in public administration information systems. The specific supporting process of communication between the client and the e-SMO system has been chosen for verification. The model of supporting communication process, created by ARIS tools, is crucial, and the structure of scripts is subsequently made. The aim of this article is to verify that the methodology is sufficient and appropriate to manage such a large project such, undoubtedly, is the e-SMO. Methodology/methods: Defined productive and non-productive processes with their defined process cuts represent a crucial category for the process structure of IS projects. This is fully accepted by the PAPRIS methodology. Process cuts are understood, in the logic modelling according to the PAPRIS methodology, as clearly defined logic directional cuts in three-dimensional space of all project processes. The process set is systemically categorized, in a given logic directional cut, into mutually disjoint process subsets, which are characterized by this particular directional operator. The directional operator always has a clear logical allocation that is based on the construction of a process view. Theoretically, an infinite number of process views can be used. One of the important issues in a methodology for the case studies includes the size of the research sample. It is usually assumed that there is no ideal number of cases and that the number between four and ten usually provides good results. Other authors defining against any quantitative standards for any determination of the sample size of the case studies, since such an approach denies the internal logic of this methodology and the richness of the information obtained from participants in the research. Research which is carried out using case studies does not aspire on compliance with the requirement the representativeness of the sample.. Methodology of case studies is among the established guidelines of qualitative research. Research on using case studies in the last 30 years has seen an extraordinary increase in social-scientific research, including research on business and management. Scientific aim: The essential aim of this study is to describe the way the process cut defines a productive process and non-productive process, in accordance with the PAPRIS methodology using the specific example. While the triggering mechanism of the project production process is an event causing its own production - i.e. the specific output with added value for the customer, the project of non-productive process is caused by the project management event. Therefore, it is caused by the need to control, monitor, track, inspect, evaluate outputs, decide and regulate the project implementation. Findings: Within the support of the communication process, two examples were used to verify the methodology. The global perspective on the process was created in ARIS tools and the communication between the call centre and the client was made in Visio tools. The PAPRIS methodology is based on the concept of process variability, which has been clearly formulated. The fundamental direction of the process development, anticipated changes and the opportunity to react to them in accordance with defined objectives of the PAIS project are guaranteed. (shrink)

Clinical ethics, like the broader field of bioethics from which it emerged, is at a critical crossroads in its development, with conflicting paths ahead. It can either claim its distinctive place in the clinical arena, insisting unapologetically on certain minimal standards of professional training, practice and competence, addressing head on debates about various models of and methodological approaches to consultation, and establishing a shared vision of the purpose and meaning of the enterprise of clinical ethics itself. Or, it can devolve (...) into a hobby that untrained, albeit interested, and generally well intentioned individuals can dabble in for fun or even profit, as they see fit, and without regard to the deep history and rich disciplinary roots of the field, the serious debates in the academic literature of bioethics, the foundational case histories and legal theories, or even any sense of professional accountability.

This study investigated the impact of online product reviews on consumers purchasing decisions by using eye-tracking. The research methodology involved development of a conceptual framework of online product review and purchasing intention through the moderation role of gender and visual attention in comments, and empirical investigation into the region of interest analysis of consumers fixation during the purchase decision process and behavioral analysis. The results showed that consumers’ attention to negative comments was significantly greater than that to positive (...) comments, especially for female consumers. Furthermore, the study identified a significant correlation between the visual browsing behavior of consumers and their purchase intention. It also found that consumers were not able to identify false comments. The current study provides a deep understanding of the underlying mechanism of how online reviews influence shopping behavior, reveals the effect of gender on this effect for the first time and explains it from the perspective of attentional bias, which is essential for the theory of online consumer behavior. Specifically, the different effects of consumers’ attention to negative comments seem to be moderated through gender with female consumers’ attention to negative comments being significantly greater than to positive ones. These findings suggest that practitioners need to pay particular attention to negative comments and resolve them promptly through the customization of product/service information, taking into consideration consumer characteristics, including gender.

Purpose This paper aims to discuss research ethics in mixed-methods research and MMR development with a focus on ethical challenges that stem from working with technical instruments such as mobile eye-trackers. Design/methodology/approach The case of an interdisciplinary mixed-methods development study that aimed at researching the impacts of emerging mobile augmented-reality technologies on the perception of public places serves as an example to discuss research-ethical challenges regarding the practical implementation of the study, data processing and management and societal implications of (...) developing instruments to track and understand human practices. Findings This study reports challenges and experiences in ethical decision-making in the practical implementation of the study regarding the relationship to research subjects, the use of mobile research instruments in public places and the interdisciplinary cooperation among research team members. Further, this paper expounds on ethical challenges and recommendations in data processing and management and with a view to societal implications of method development and the aspirations of transdisciplinarity. This study concludes that institutionalized ethics need to become more flexible, while applied ethics and reflection must make their entry into university curricula across disciplines. Originality/value Complex interdisciplinary mobile and mixed-methods projects that involve sensors and instruments such as mobile eye-trackers are on the rise. However, there is a significant lack of engagement with practical research ethical challenges, practices and requirements in both mixed-methods and method-development literature. By taking a context- and process-oriented perspective focusing on doing ethics, the paper contributes a concrete empirical case to these underdeveloped fields. (shrink)

It has been widely recognized since ancient times that a standard way to resolve disagreement is for one party to extract concessions from the other which he or she is less prepared to give up than his original thesis. Central to this methodology is specifying the various forms of consequence which bear on matters already conceded. Not all disagreements are responsive to this methodology. I shall speak of a class of disagreements as intractable when parties are unwilling to (...) “split the difference” or to “agree to disagree” and yet are unable to agree on procedures to resolve their original disagreement.. When intractable disagreements turn on values that are widely held and widely judged to be of the first importance, intractable disagreements constitute an apparent impediment to social policy formation. An urgent question is this: “Is coherent and supportable public policy possible concerning matters subject to intractable disagreement?”. (shrink)
