Recent debates about memetics have revealed some widespread misunderstandings about Darwinian approaches to cultural evolution. Drawing from these debates, this paper disputes five common claims: (1) mental representations are rarely discrete, and therefore models that assume discrete, gene-like particles (i.e., replicators) are useless; (2) replicators are necessary for cumulative, adaptive evolution; (3) content-dependent psychological biases are the only important processes that affect the spread of cultural representations; (4) the “cultural fitness” of a mental representation can be inferred from its (...) successful transmission; and (5) selective forces only matter if the sources of variation are random. We close by sketching the outlines of a unified evolutionary science of culture. (shrink)

Pragmatic presupposition is analyzed in this paper as grounded on an implicit reasoning process based on a set of presumptions, which can define cultural differences. The basic condition for making a presupposition can be represented as a reasoning criterion, namely reasonableness. Presuppositions, on this view, need to be reasonable, namely as the conclusion of an underlying presumptive reasoning that does not or may not contain contradictions with other presumptions, including the ordering of the hierarchy of presumptions. Presumptions are in turn (...) analyzed considering their nature and their hierarchy, namely their object and their possible contextual backing, which eliminates some of their possible defaults. This analysis of presupposition brings to light the relationship between communicative infelicities or misunderstandings deriving from presuppositional failures and the underlying system of presumptions and presumptive reasoning. This approach can be applied to the investigation of communicative problems within the medical context, and more precisely the communication in diabetes cases. (shrink)

In Pregnancy and superior moral status: A proposal for two thresholds of personhood, Robinson argues that pregnant women are unique beings with superior moral status (MS) to that of other adult human beings. Robinson’s defence of this view relies on metaphysical and moral claims. The first set of claims concerns the ontological status of the pregnant woman, whom she considers a ‘unique organism’,‘more than just one person’and ‘numerically increased’.1 The second set of claims concerns the ‘superior’ MS of the pregnant (...) woman. In this commentary, we address this second set of claims and argue that Robinson’s view rests on a misunderstanding of the concept of MS and its role in supplying reasons for action (and forbearance from action). While we welcome the conclusion of Robinson’s argument—which we take to be that pregnant women ought to be treated with more consideration—on an appropriate understanding of MS, her argument does not yield that conclusion at all. We feel strongly that medical ethics needs to be grounded in good philosophy and worry that too much of the literature falls short of this ideal. As such, the spirit in which we write this commentary is that of constructive criticism. ### One plus one equals one plus one and the grounds of MS The philosophical literature on the grounds of MS essentially addresses the question of what properties (Ps) determine whether an agent (A) has MS.1 Examples of Ps are: sophisticated cognitive capacities,2 such as the capacity to value, being self-aware or rational, or more controversially, ….

Writers on organisational change often refer to the cosmology of Heraclitus in their work. Some use these references to support arguments for the constancy and universality of organisational change and the consignment to history of organisational continuity and stability. These writers misunderstand the scope of what Heraclitus said. Other writers focus exclusively on the idea that originated with Heraclitus that the universe is composed of processes and not of things. This idea, which has been particularly associated with Heraclitus’s thought from (...) the time of Plato, does indeed provide a rich source of insights into organisational analysis, not least the current trends towards giving proper attention to processual studies of organisational change. Yet there is some uncertainty as to whether Heraclitus actually said that the universe was composed exclusively of processes rather than things, and even if that was what he thought, he intended his ideas on flux to be understood not in isolation but in the context of other aspects of his cosmology. Writers on organisational change seldom make reference to this wider context. Heraclitus was a rational but also a religious thinker. A central element in his thought was the notion of divine Justice, which to a Greek of his era meant the order of the universe. Remote as his Olympian theology may seem today, it sets a crucial and entirely rational context for understanding his ideas about flux. It means that ideas about continuity and stability were quite as important in Heraclitus’s cosmology as his more commonly quoted ideas about change. This paper sets out an overview of Heraclitus’s philosophy, insofar as it appears to have potential relevance to organisational analysis, and discusses how far it supports or contradicts the ideas that organisational change scholars have drawn from it.

This paper argues that vice-charging, the practice of charging other persons with epistemic vice, can itself be epistemically vicious. It identifies some potential vices of vice-charging and identifies knowledge of other people as a type of knowledge that is obstructed by epistemically vicious attributions of epistemic vice. The hazards of vice-charging are illustrated by reference to the accusation that parents who hesitate to give their children the MMR triple vaccine are guilty of gullibility and dogmatism. Ethnographic and sociological research is (...) used to make the case that this charge is, in a significant range of cases, epistemically unjust and hinders attempts to make sense of vaccine hesitancy. This epistemic injustice consists in the representation of vaccine hesitant parents as less than full epistemic agents. A case is made for a more tolerant and inclusive approach, not only to vaccine hesitancy but also to other forms of unorthodoxy or non-compliance. The primary objective in these cases should be to achieve Verstehen of seemingly alien outlooks and practices so that policy makers and practitioners in public services can more effectively educate a sceptical public about the risks of vaccine hesitancy.

The article focuses on understanding some of the self-evident premises of the philosophy of the 17th–19th centuries that make up the horizon of the Enlightenment. One of these premises is Immanuel Kant’s idea of independent thinking. Based on the analysis of the polemics of Kant and Friedrich Heinrich Jacobi about the “extrasensible abilities” of the reason, the question is raised about the possibility of understanding someone else’s concept based on other existential preferences. Answering this question, we distinguish between the concept (...) of the Enlightenment and the practical principle of the Enlightenment and show that the supporter of the ideology of the Enlightenment (Kant) and his critic (Jacobi) appear in the light of the principle of independent thinking as the spokesmen of the spirit, not the letter of the Enlightenment. A condition for understanding someone else’s concept is a productive misunderstanding, which is one of the aspects of the principle of independent thinking: the acceptance of the self-evident as incomprehensible, the shift of one’s attention to one’s own how-being and the perception of thought as a gift.

Misunderstanding Science? offers a challenging new perspective on the public understanding of science. In so doing, it also challenges existing ideas of the nature of science and its relationships with society. Its analysis and case presentation are highly relevant to current concerns over the uptake, authority, and effectiveness of science as expressed, for example, in areas such as education, medical/health practice, risk and the environment, technological innovation. Based on several in-depth case-studies, and informed theoretically by the sociology of scientific knowledge, (...) the book shows how the public understanding of science questions raises issues of the epistemic commitments and institutional structures which constitute modern science. It suggests that many of the inadequacies in the social integration and uptake of science might be overcome if modern scientific institutions were more reflexive and open about the implicit normative commitments embedded in scientific cultures.

Intelligibility relates to a person’s agency in guiding their behavior to be logical and reasonable, and it makes sense during action. However, it does not always happen. Sometimes, intelligibility fails, and the subject’s actions become distanced from what had previously made sense to them or others. At that moment, what I have called misunderstandings within the agency appear. When the emotional process interferes with the action process, it is one of the causes of misunderstandings within the agency. Then, (...) emotions interfere with the action and produce a cognitive dissociation that makes it difficult for the agents to interpret what is happening in the scene. It breaks between intelligibility and meaning. This also creates problems of understanding and communication. This is why the analysis of the misunderstandings within the agency is of such great importance. (shrink)

Today, the tone of discussion in the public sphere is dominated by misunderstanding. A common assumption is that misunderstanding comes from a failure of understanding. This article argues that misunderstanding is in fact a type of meaning change. To fully understand the contrast between misunderstanding as a failure of understanding and misunderstanding as a type of meaning change, the article uses Ludwig Wittgenstein and Hans-Georg Gadamer as a starting point to tease out an unthought assumption. Both thinkers challenge traditional preconceptions (...) of how language shapes understanding and they make prominent use of the concept of misunderstanding to do so. Yet both rely on a de facto model of misunderstanding as a failure of understanding. To consider an alternative notion of misunderstanding, the article looks at examples from thinkers influenced by Wittgenstein's and Gadamer's philosophy. Finally, the article concludes by positing a new definition of misunderstanding. (shrink)

The commonest misunderstanding of Schopenhauer is that he taught, contradicting Kant, that we can have direct knowledge of the noumenon. Then there is the mistake that this noumenon is the will understood in a conative sense, the will as we experience it in agency, or the will to live, or the will to power. A careful reading of Schopenhauer's work is able to show that these are misinterpretations. He does not believe we can know the noumenon; and by ‘will’ he (...) means a blind force that is as present in inorganic nature as elsewhere. It was an error on Schopenhauer's part to use the term ‘will’ in a way that invites these misunderstandings; but the damage has been done. (shrink)

Traditionally, intelligibility is associated with rationality. It is also associated with the meaning and understanding of the agent’s actions when interacting in a context. What is proposed in this work is an analysis – at the moment in which the agent is interacting – of what happens when intelligibility and meaning are decoupled. It causes a person’s actions to be misunderstood or misinterpreted by others. It is even possible that the same person will not understand, later, why she has acted (...) the way she has. The explanation proposed is that this link is broken when the action process, made up of the three stages of action, is not developed correctly. This results in misunderstandings that, because they are directly related to the action, I have called misunderstandings within agency. The analysis of this kind of misunderstanding could be essential to understanding the conflicts that arise in the communicative act and mutual understanding. (shrink)

Developmental systems theory (DST) is a general theoretical perspective on development, heredity and evolution. It is intended to facilitate the study of interactions between the many factors that influence development without reviving `dichotomous' debates over nature or nurture, gene or environment, biology or culture. Several recent papers have addressed the relationship between DST and the thriving new discipline of evolutionary developmental biology (EDB). The contributions to this literature by evolutionary developmental biologists contain three important misunderstandings of DST.

This paper considers the role of ‘vices of culture’ in Immanuel Kant’s account of radical evil and education. I argue that Kant was keenly aware of a uniquely human tendency to allow a self-centered concern for status to misunderstand or co-opt the language of dignity and equal worth for its own purposes. This tendency lies at the root of the ‘vices of culture’ and ‘aggravated vices’ that Kant describes in the Religion and Doctrine of Virtue, respectively. When it comes to (...) moral education, then, it will be crucial that the developing agent have a clear understanding of the shared dignity of rational agents and the particular duties that are defined, in part, by their tendency to alter status among agents. I argue that the casuistical questions that Kant attaches to these discussions in the Doctrine of Virtue are an example of a pedagogical device that might help pupils to overcome this tendency so closely associated with radical evil.

Clinical trials play a crucial role in generating evidence about healthcare interventions and improving outcomes for current and future patients. For individual trial participants, however, there are inevitably trade‐offs involved in clinical trial participation, given that trials have traditionally been designed to benefit future patient populations rather than to offer personalised care. Failure to understand the distinction between research and clinical care and the likelihood of benefit from participation in clinical trials has been termed the ‘therapeutic misconception’. The evolution of (...) the clinical trials landscape, including greater integration of clinical trials into healthcare and development of novel trial methodologies, may reinforce the significance of the therapeutic misconception and other forms of misunderstanding while at the same time (paradoxically) challenging its salience. Using cancer clinical trials as an exemplar, we describe how methodological changes in early‐ and late‐phase clinical trial designs, as well as changes in the design and delivery of healthcare, impact upon the therapeutic misconception. We suggest that this provides an impetus to re‐examine the ethics of clinical research, particularly in relation to trial access, participant selection, communication and consent, and role delineation.

Lifelines by Steven Rose is supposed to present a new perspective on biology replacing an emphasis on genes with one on organisms. However, much of the book is a highly biased critique of sociobiology and behavior genetics. Some of the flaws in Rose's description and depiction of these fields are presented and refuted. Also, it would appear that these aspects of the book and many others are, in fact, related more to Rose's perennial concern for the ideology, social origins or (...) social consequences of behavioral biology. These concerns are, I believe based, in part, upon Rose's misunderstandings and misinterpretations of genetics, behavior genetics, and sociobiology. (shrink)

This paper uses examples of conversational understandings, misunderstandings and non-understandings to explore the role of prototypes and schemata in conversational understanding. An investigation of the procedures by which we make sense of lexical items in utterances by fitting prototypes into schemata is followed by an examination of how schemata are instantiated across conversational sequences by means of topics. In interaction, conflicts over meaning illuminate the decisive role of social and cultural factors in understanding. Overall, understanding is seen to be (...) critically dependent on principles of categorisation and contrast, which form the basis of both cognitive and sociocultural means of organisation. (shrink)

Basic concepts of communicational elements are explained: culturally institutionalized or individually internalized conscious or unconscious, intentional and unintentional encoding and decoding systems of verbal and nonverbal behavior, metacommunicational cues, various modes of communication , the rôle of situational context and of background information.Examples of complex misunderstandings in interpersonal interactions are given and analysed. This analytical method has been useful in psychiatry as well as in daily life situations.

Two important objections have been raised against exclusivist public reason. First, it has been argued that EPR entails an unjust burden for citizens who want to appeal to non-public reasons, especially religious reasons. Second, it has been argued that EPR is based on a problematic conception of religious reasons and that it ignores the fact that religious reasons can be public as well. I defend EPR against both objections. I show that the first objection conflates two ideas of public justification (...) and that the second objection conflates two ways to understand and identify religious reasons. Ultimately, it turns out that those who defend such objections actually share the concerns that justified EPR in the first place. In other words, if we are clear about the idea of public justification and the kind of religious reasons that EPR is really about, it appears that justificatory liberals are in fact all exclusivists.

The public rejection of scientific claims is widely recognized by scientific and governmental institutions to be threatening to modern democratic societies. Intense conflict between science and the public over diverse health and environmental issues have invited speculation by concerned officials regarding both the source of and the solution to the problem of public resistance towards scientific and policy positions on such hot-button issues as global warming, genetically modified crops, environmental toxins, and nuclear waste disposal. The London Royal Society’s influential report (...) “Public Understanding of Science”, which spearheaded the now-thriving area of science... (shrink)

The long‐standing issue of Wittgenstein's controversial remarks on Gödel's Theorem has recently heated up in a number of different and interesting directions [, , ]. In their , Juliet Floyd and Hilary Putnam purport to argue that Wittgenstein's‘notorious’ “Contains a philosophical claim of great interest,” namely, “if one assumed. that →P is provable in Russell's system one should… give up the “translation” of P by the English sentence ‘P is not provable’,” because if ωP is provable in PM, PM is (...) ω ‐inconsistent, and if PM is ω‐inconsistent, we cannot translate ‘P’as ’P is not provable in PM’because the predicate‘NaturalNo.’in ‘P’“cannot be…interpreted” as “x is a natural number.” Though Floyd and Putnam do not clearly distinguish the two tasks, they also argue for “The Floyd‐Putnam Thesis,” namely, that in the 1930's Wittgenstein had a particular understanding of Gödel's First Incompleteness Theorem. In this paper, I endeavour to show, first, that the most natural and most defensible interpretation of Wittgenstein's and the rest of is incompatible with the Floyd‐Putnam attribution and, second, that evidence from Wittgenstein's Nachla strongly indicates that the Floyd‐ Putnam attribution and the Floyd‐Putnam Thesis are false. By way of this examination, we shall see that despite a failure to properly understand Gödel's proof—perhaps because, as Kreisel says, Wittgenstein did not read Gödel's 1931 paper prior to 1942‐Wittgenstein's 1937–38, 1941 and 1944 remarks indicate that Gödel's result makes no sense from Wittgenstein's own perspective.

This article investigates some of the various ways in which theorists have used Machiavelli (and more specifically The Prince) in a business and management context and suggests that the two most common approaches, the use of metaphor and the use of analogy, are both flawed. Metaphor often relies on a reading of Machiavelli that cannot be sustained, whereas analogy takes Machiavelli too far out of historical context. This article discusses how business and management can more usefully incorporate Machiavelli’s ideas by (...) placing them within a tradition of discourse, along the lines of Lockyer’s historical method. We outline three potential discourses: those of humanism; of guides to leadership; and of power. In so doing the article suggests that historical texts (in particular Machiavelli) can prove useful to students and practitioners of business and management. (shrink)

Abstract The paper examines the differences between Kuhn's account, in The Structure of Scientific Revolutions, of the sciences as necessarily communal activities with internally set standards of procedure and achievement, and that view of the sciences which calls itself ?Scientific Realism? and regards them as striving toward, and perhaps asymptotically approaching, some external and objective reality that bestows truth or falsity on scientific theories. The main argument turns on Poincaré's demonstration that Newton's Second Law (f = ma) is not a (...) testable, provable proposition with a truth value, but something that is simply adopted. It is adopted in the light of experience, certainly, but there is no logical necessity in the adoption. My suggestion is that it is a ?way of looking? and ?a method of analysis? and that the necessity of its adoption by any individual lies in its being a necessary condition of entry into the scientific community. That community itself adopts ways of looking or methods of analysis for their fruitfulness in dealing with old problems and defining new ones. Incoherences in the ?approach? account of scientific progress are looked at, and the individualistic assumptions that motivate it. These require the sciences to be presented as the source and basis of agreement and community amongst separated individuals. This picture and its requirement inverts reality as well as Kuhn's account, which makes community and agreement the starting point. The notion of reality as a transcendental convergence point becomes redundant. The old problem of the incommensurability of paradigms is discussed by relating them to the notions of ways of looking and methods of analysis. These may be incompatible in that one cannot look at things in two different ways at once, but at the same time they cannot be measured on any common scale. (shrink)

“Our acts shall be misunderstood [falsch verstanden], as Epicurus is misunderstood! […] I want to be misunderstood for a long time”.1 So proclaims Nietzsche in a notebook passage from 1883, thereby making one of several positive claims for identification with the Hellenistic Greek philosopher from Samos.2 Epicurus, the full remark suggests, was untimely—misunderstood, unappreciated by his contemporaries—much as Nietzsche himself aims to be untimely; and this point is hardly the only moment of convergence between the two thinkers. Although he is (...) not quite the most discussed Greek philosopher in Nietzsche’s writing—Plato and Socrates appear more frequently— Epicurus is an undeniably persistent.. (shrink)

This article defends Ernesto Laclau against the charge that his work, manifested most clearly in On Populist Reason, affirms an authoritarian politics to account for the genesis of collective identity. To outline this, I read Laclau’s thought through three logics – termed the logics of universal imposition, negation, and symbolic mediation – to argue that he rejects the first but adopts the latter two, with the logic of symbolic mediation being particularly important. Rather than unity resulting when distinct groups agree (...) over a positive meaning of a signifier or when it is imposed on them by an authoritarian leader, Laclau claims that unity depends upon the existence of empty signifiers that lack substantial meaning. Engaging with the structure and functioning of this lack, I utilize Laclau’s notion of ‘constitutive distortion’ to highlight an often overlooked structural component of his account that I call ‘misunderstanding’. Rather than a negative occurrence, misunderstanding is a fundamental and positive condition of collective identity because it permits the various groups to affirm different, even contradictory, positions regarding the meaning of empty signifiers (permitted by the fundamental lack of such signifiers), all the while (through the shared but mistaken belief that they agree over its meaning) binding each group into a collective identity. This misunderstanding, which must remain hidden from the participants of the collective identity, is a fundamental condition of the process through which collective identity is created and sustained because it permits the various groups to believe that they share a collective identity while maintaining the heterogeneity that is necessary, on Laclau's telling, for the continued existence of the collective.

Wittgenstein seeks to throw light on our concept of understanding by looking at how misunderstandings arise and what kinds of failure they involve. He discerns a peculiar sort of misunderstanding in the writings of the social anthropologist James Frazer. In Frazer’s hands, the anthropological project of enabling us to understand human behavior seems to yield the result that there are certain forms of human behavior that simply cannot be understood. The source of Frazer’s misunderstanding, according to Wittgenstein, is that (...) he places narrow requirements on what could count as meaningful, prior to and independently of his encounter with the subjects of his interpretation. Frazer, like some of the philosophers Wittgenstein addresses in his other works, succumbs to nonsense in his very attempt to draw the limits of sense. My aim in this chapter is to clarify the connections between Wittgenstein’s criticism of Frazer and his criticism of his fellow philosophers, in particular of Frege. The materials I draw on stem from various periods in Wittgenstein’s career, and they reveal, in my mind, an important continuity in Wittgenstein’s thought: addressing misunderstanding, in Wittgenstein’s view, is fundamentally an ethical problem, not a theoretical one.

There is no paucity of academic studies, medical literature, or media attention given to concerns about gender ideology and being transgender. When reporting their findings, however, some researchers and practitioners working from a purely secular perspective overstep medical observations to make metaphysical pronouncements. This causes considerable confusion and stifles dialogue that could occur if the line between medicine and philosophy were clearly delineated. Properly understood, transgender describes an observable distress due to incongruence between one’s birth sex and gender identity. Conversely, (...) gender ideology is a metaphysical conclusion, which argues that a person’s gender is fluid and open to personal choice. Clearly distinguishing between these can help families, clinicians, and society provide medically appropriate and culturally competent care to those with gender dysphoria, especially children.

Taking as its point of departure a systematic presentation of the various types of misunderstandings, ranging from the most banal and benign to the most perverse and pernicious, this text principally examines the ways in which they can pave the way for disagreement. While it is possible that a rational examination of motives and sources pertaining to a misunderstanding may help to minimize its undesirable effects upon communication, a misunderstanding may also signal the incontrovertible and irresolvable nature of a (...) disagreement. This paper, therefore—while basically Habermasian in its orientation—also questions the validity of Jürgen Habermas's premises regarding the ethics of communication: the scope given to speculative reason and the effectiveness of an explicative metadiscourse for clarifying misunderstanding or resolving conflicts; the possibility of authentic discourse in certain conflict situations; consensus as the ultimate goal of dialogue. Although Habermas stipulates that the expectation of validity is incumbent upon any authentic exchange, this paper underscores instead the expectation of satisfaction, which compels all individuals seeking to communicate. Through this comparison, the paper attempts to show that even the most tenacious disagreement originates in this affective nexus, and to show as well how we may construct ethical practices that are contingent upon disagreement.

To anyone who has been engaged in teaching and studying Plato, particularly the Republic , for the last thirty or forty years, one fact must stand out with special prominence. That is the remarkable increase during that period of the direct applicability of Plato's discussions to our own problems. Thirty-five years ago the concrete situations which Plato had in mind in these discussions, the general assumptions at the back of them, the possibilities for good or evil that he envisaged, would (...) all seem to the student of that time remote and almost unreal, and it required a considerable exercise of the imagination to discover that there were certain underlying ideas in them which had application to our own time. If we wanted contemporary illustrations of the rise of a tyrant we had to turn to some of the most backward States in South America. The idea of a completely planned society existed only in the minds of the writers of Utopias, to whom we were accustomed, sometimes, to say rather patronizingly that they had forgotten that constitutions, grow and are not made. We could study the criticisms of democracy as an intellectual exercise without any feeling that they might be one day applied in practice. How different is the situation now! Many of the possibilities are as near for us as they were to Plato. Many of the general ideas of Plato's day are as readily assumed by us as they were by him. Indeed the difficulty now is greater in trying to gain a sympathetic hearing for the ideas of thirty or forty years ago than for the ideas of the fourth century b.c. (shrink)

This chapter discusses the mistaken ways in which Beauvoir's work is interpreted by some of France's leading feminists. It counterposes their reception by arguing that Beauvoir's concept of the free ethical way of life is Hegelian rather than Kantian in character. In The Ethics of Ambiguity she outlines ethics as an always situated, embodied life project, a perspective that is the theoretical framework of The Second Sex as well and that calls for a plural feminism in world perspective.

This paper addresses two questions about audience misunderstandings of contemporary art. First, what is the institution’s responsibility to prevent predictable misunderstandings about the nature of a contemporary artwork, and how should this responsibility be balanced against other considerations? Second, can an institution ever be justified in intentionally mounting an inauthentic display of an artwork, given that such displays are likely to mislead? I will argue that while the institution has a defeasible responsibility to mount authentic displays, this is (...) not always sufficient to avoid misunderstanding; the institution will sometimes need to supply auxiliary information. And even where competing considerations require mounting an inauthentic display, thoughtful museum practice can promote the audience’s ability to grasp the work. The argument will be developed with consideration of artworks by El Anatsui, Lygia Clark, and Glenn Ligon. (shrink)

Online educational technologies offer opportunities for providing individualized feedback and detailed profiles of students' skills. Yet many technologies for mathematics education assess students based only on the correctness of either their final answers or responses to individual steps. In contrast, examining the choices students make for how to solve the equation and the ways in which they might answer incorrectly offers the opportunity to obtain a more nuanced perspective of their algebra skills. To automatically make sense of step‐by‐step solutions, we (...) propose a Bayesian inverse planning model for equation solving that computes an assessment of a learner's skills based on her pattern of errors in individual steps and her choices about what sequence of problem‐solving steps to take. Bayesian inverse planning builds on existing machine learning tools to create a generative model relating (mis)‐understandings to equation solving choices. Two behavioral experiments demonstrate that the model can interpret people's equation solving and that its assessments are consistent with those of experienced teachers. A third experiment uses this model to tailor guidance for learners based on individual differences in misunderstandings, closing the loop between assessing understanding, and using that assessment within an educational technology. Finally, because the bottleneck in applying inverse planning to a new domain is in creating the model of possible student misunderstandings, we show how to combine inverse planning with an existing production rule model to make inferences about student misunderstandings of fraction arithmetic.

Schober et al. describe two studies on how survey interview respondents misunderstand interview questions. After answering a survey, participants are given standardized definitions of the questions they have just answered. Even apparently simple questions such as “Have you smoked more than 100 cigarettes?” are interpreted very differently by participants. Moreover, clarifying the meaning of the definitions with the interviewer does not always help resolve the miscommunication.
