There is a large gap between the specialized knowledge of scientists and laypeople’s understanding of the sciences. The novice-expert problem arises when non-experts are confronted with (real or apparent) scientific disagreement, and when they don’t know whom to trust. Because they are not able to gauge the content of expert testimony, they rely on imperfect heuristics to evaluate the trustworthiness of scientists. This paper investigates why some bodies of scientific knowledge become polarized along political fault lines. (...) Laypeople navigate conflicting epistemic and social demands in their acceptance of scientific testimony; this might explain their deference to scientific fringe theories, which often goes together with denying established scientific theories. I evaluate three approaches to mitigate denialism: improving the message, improving the messenger, and improving the environment in which the message is conveyed. (shrink)

Expert-informed public policy often depends on a degree of public trust in the relevant expert authorities. But if lay citizens are not themselves authorities on the relevant area of expertise, how can they make good judgements about the trustworthiness of those who claim such authority? I argue that the answer to this question depends on the kind of trust under consideration. Specifically, I maintain that a distinction between epistemic trust and recommendation trust has consequences for novices judging the (...) trustworthiness of experts. I argue for this by identifying the unique difficulties that emerge when a novice is asked not just to believe expert testimony, but to follow expert recommendations. I outline criteria for novice judgements of expert trustworthiness that have been proposed by Elizabeth Anderson and show that novel problems emerge for her criteria when we shift focus from epistemic trust to recommendation trust. More is needed when we are asked not just to believe the experts but to act as they recommend, because novices looking for trustworthy expert recommendations need to establish whether the recommended course of action supports what is important to them and accords with their values.

This paper tackles the problem of defining what a cognitive expert is. Starting from a shared intuition that the definition of an expert depends upon the conceptual function of expertise, I shed light on two main approaches to the notion of an expert: according to novice-oriented accounts of expertise, experts need to provide laypeople with information they lack in some domain; whereas, according to research-oriented accounts, experts need to contribute to the epistemic progress of their (...) discipline. In this paper, I defend the thesis that cognitive experts should be identified by their ability to perform the latter function rather than the former, as novice-oriented accounts, unlike research-oriented ones, fail to comply with the rules of a functionalist approach to expertise.

This paper aims to defend the Expertise Defense by addressing the problem of disanalogy, which represents one of the two main critiques against this argument. The Expertise Defense is an argument which defends the notion that philosophers’ judgments are more reliable than those of novices by making analogies between philosophy and other fields in which experts’ judgments are given a privileged position. Conventionally, this line of argumentation has aimed to demonstrate that philosophers' intuitions about thought experiments or metaphysical questions (...) are not as susceptible to being distorted by unrelated factors as those of novices. However, this paper reinterprets the Expertise Defense, proposing that it claims that philosophers' intuitions are considerably more reliable than novices, even if they are still susceptible to distorting factors. By adopting this interpretation, the current paper effectively counters the empirical objection that philosophers' intuitions are subject to distortion. Furthermore, I respond to the disanalogy problem, which contends that there is no meaningful analogy between philosophy and other domains because philosophical experience does not contribute significantly to philosophical intuitions. In response to this, I present a new model of philosophical expertise. According to this model, philosophical training plays a vital role in shaping philosophical intuitions by enabling expert philosophers to comprehend philosophical problems accurately and form well-grounded intuitions about them. Additionally, I provide empirical evidence supporting this model, particularly in the context of the debates about free-will. While the extent to which this model can be generalized remains an empirical question, it seems reasonable to think that it could plausibly be extended to other debates. (shrink)

In recent epistemology many philosophers have adhered to a moderate foundationalism according to which some beliefs do not depend on other beliefs for their justification. Reliance on such ‘basic beliefs’ pervades both internalist and externalist theories of justification. In this article I argue that the phenomenon of perceptual learning – the fact that certain ‘expert’ observers are able to form more justified basic beliefs than novice observers – constitutes a challenge for moderate foundationalists. In order to accommodate perceptual (...) learning cases, the moderate foundationalist will have to characterize the ‘expertise’ of the expert observer in such a way that it cannot be had by novice observers and that it bestows justification on expert basic beliefs independently of any other justification had by the expert. I will argue that the accounts of expert basic beliefs currently present in the literature fail to meet this challenge, as they either result in a too liberal ascription of justification or fail to draw a clear distinction between expert basic beliefs and other spontaneously formed beliefs. Nevertheless, some guidelines for a future solution will be provided. (shrink)

The acquisition of a new skill usually proceeds through five stages, from novice to expert, with a sixth stage of mastery available for highly motivated performers. In this chapter, we re-state the six stages of the Dreyfus Skill Model, paying new attention to the transitions and interrelations between them. While discussing the fifth stage, expertise, we unpack the claim that, “when things are proceeding normally, experts don’t solve problems and don’t make decisions; they do what normally works” (Dreyfus (...) & Dreyfus, 1988, pp. 30 – 31). This leads us to offer an account of the “perspectival deliberation” that arises for experts and masters and that is distinct from the calculative deliberation characteristic of the lower stages of skillfulness.

According to a recent account of epistemic authority proposed by Linda Zagzebski (2012), it is rational for laypersons to believe on authority when they conscientiously judge that the authority is more likely to form true beliefs and avoid false ones than they are in some domain. Christoph Jäger (2016) has recently raised several objections to her view. By contrast, I argue that both theories fail to adequately capture what epistemic authority is, and I offer an alternative account grounded in the (...) abilities that different kinds of authorities are required to possess.

Recent advances in neuroimaging technologies have rendered multimodal analysis of operators’ cognitive processes in complex task settings and environments increasingly more practical. In this exploratory study, we utilized optical brain imaging and mobile eye tracking technologies to investigate the behavioral and neurophysiological differences among expert and novice operators while they operated a human-machine interface in normal and adverse conditions. In congruence with related work, we observed that experts tended to have lower prefrontal oxygenation and exhibit gaze patterns that (...) are better aligned with the optimal task sequence with shorter fixation durations as compared to novices. These trends reached statistical significance only in the adverse condition where the operators were prompted with an unexpected error message. Comparisons between hemodynamic and gaze measures before and after the error message indicated that experts’ neurophysiological response to the error involved a systematic increase in bilateral dorsolateral prefrontal cortex (dlPFC) activity accompanied with an increase in fixation durations, which suggests a shift in their attentional state, possibly from routine process execution to problem detection and resolution. The novices’ response was not as strong as that of experts, including a slight increase only in the left dlPFC with a decreasing trend in fixation durations, which is indicative of visual search behavior for possible cues to make sense of the unanticipated situation. A linear discriminant analysis model capitalizing on the covariance structure among hemodynamic and eye movement measures could distinguish experts from novices with 91% accuracy. Despite the small sample size, the performance of the linear discriminant analysis combining eye fixation and dorsolateral oxygenation measures before and after an unexpected event suggests that multimodal approaches may be fruitful for distinguishing novice and expert performance in similar neuroergonomic applications in the field.

On peut identifier deux principales caractéristiques de Wikipédia pour expliquer son succès et sa spécificité. La première est sa liberté de modification et d’accès. La deuxième réside dans le système organisationnel ascendant (bottom-up) et égalitaire où les articles ne proviennent plus d’experts sélectionnés pour être ensuite distribués à la foule mais sont, au contraire, produits par une base composée d’amateurs inconnus. Ces deux caractéristiques, associées au succès populaire et qualitatif de l’encyclopédie, laissent peu de place à l’expertise individuelle (en particulier (...) à l’expertise académique et scientifique). De plus, le constat de l’auto-correction dynamique de l’encyclopédie a effacé l’idée d’une vérification a posteriori des articles par un ou plusieurs experts du domaine. La force de Wikipedia semble alors résider dans une harmonie systématique inhérente à sa forme. -/- Dans cet article, je tente de montrer qu’il faut dépasser l’antagonisme entre amateurs et experts (crowds versus experts) et que c’est justement le caractère libre et égalitaire de Wikipedia qui rend nécessaire une réflexion épistémologique sur l’expertise au sein de cette encyclopédie. Je prends l’exemple du problème du novice et des deux experts théorisé par Alvin Goldman (2001). Appliqué à Wikipédia, ce problème pose la question des options épistémiques disponibles pour les wikipédiens confronté à une guerre d’édition. Outre les solutions classiques (recours à des meta-experts, décision majoritaire, discussion), Goldman avance l’idée d’une prise en compte, par le novice, des (in)succès épistémiques précédents des différents experts en désaccord. Un expert s’étant majoritairement trompé par le passé en devient ainsi moins crédible et inversement. Même si cette solution pose un certain nombre de problèmes, elle semble particulièrement propice à étudier l’expertise au sein de Wikipédia. Elle permet de comprendre (1.) qu’il existe déjà une expertise wikipedienne régie par certaines règles et (2.) qu’il est possible d’aménager une place aux experts (en particulier scientifiques) dans cette encyclopédie libre. Au final, pour comprendre et améliorer la place de l’expertise dans Wikipedia, il semble qu’il faille adopter une certaine conception de l’expertise, centrée sur l’agent plus que sur le contenu épistémique. Cette conclusion soulève un paradoxe, Wikipedia s’étant construite sur l’anonymat des auteurs et la primauté du contenu. (shrink)

Making Sense of Messages Making Sense of Messages, now in its second edition, retains the apprenticeship approach which facilitates effectively learning the complex content and skills of rhetorical theory and criticism. A new chapter on “The Rhetoric of Ignorance” provides needed theory and examples that help students deal with the new rhetorical landscape marked by such discursive complexities as “fake news,” “whataboutism,” and denial of science that creates rather than reduces uncertainty in public argument. A new chapter, “Curating and Analyzing (...) Multimodal Mediated Rhetoric,” deals with problems of media criticism in the digital age. It provides theory, models of application, and commentary that help novice critics understand and rnindfully practice criticism that leads to insight, not mere opinion. Throughout the book, extended and updated examples and commentaries are designed to promote “novice—to—expert” agency in students. This textbook is ideal for introductory courses in contemporary rhetoric, rhetorical criticism, and critical analysis of mass media.

Valerie Tiberius’s Moral Psychology: An Introduction is a gem. Clearly and crisply drawing on empirical and non-empirical work in philosophy and psychology, Tiberius illuminates the many ways in which the issues central to moral psychology arise in and bear on normative ethics, meta-ethics, and the study of agency and responsibility. Tiberius articulates deep debates, complex concepts and rationales, intricate empirical data points, and obscure assumptions with an enviable ease. Further, though the book is pitched in a manner that is accessible (...) to novices, it offers experts an opportunity to see their discipline through a very informed and distinctive lens.

West Nile virus (WNV) is a mosquito-borne flavivirus that was first identified in 1937 in the West Nile district of Uganda. The virus is now widely distributed throughout the world and is considered a significant public health concern. WNV is primarily transmitted to humans through the bite of infected mosquitoes, with birds serving as the primary reservoir host. Most people infected with WNV will not experience any symptoms, but approximately 1 in 5 will develop a fever, and a smaller percentage (...) may develop more severe symptoms such as meningitis or encephalitis. There is no specific treatment for WNV infection, and prevention efforts focus on mosquito control measures and personal protective measures to avoid mosquito bites. While WNV is not typically considered a major threat to human health, outbreaks have occurred sporadically in various parts of the world, and ongoing surveillance and research are necessary to better understand and control the virus. Objectives: This paper will solve the problems of treatment of West Nile virus (WNV) through correct diagnosis and treatment. Methods: In this research, we provide an expert system for the diagnosis of West Nile virus (WNV) which will help doctors to explore everything related to the problems of West Nile virus (WNV). We look forward to providing simplified answers to West Nile virus (WNV). (shrink)

Questions about knowledge in expert sport are not only of applied significance: they also take us to the heart of foundational and heavily-disputed issues in the cognitive sciences. To a first (rough and far from uncontroversial) approximation, we can think of expert ‘knowledge’ as whatever it is that grounds or is applied in (more or less) effective decision-making, especially when in a competitive situation a performer follows one course of action out of a range of possibilities. In these (...) research areas, studies of motor expertise have for many years actively contributed to broader debates in philosophy and psychology (Abernethy, Burgess-Limerick, & Parks, 1994; Williams, Davids, & Williams, 1999). When we navigate the world flexibly and more or less successfully, how much is this due to a capacity to represent it? In considering alternative options, or planning future actions, we seem to transcend our present environment in some way: what is the balance or relation here between highly-tuned bodily dispositions and background knowledge of the world and its patterns? What changes in these regards as we gain experience and adapt to more complex and challenging environments? Is know-how fundamentally different in kind from ordinary factual knowledge of the world, or knowledge-that? And if expertise in a domain does involve or depend on a knowledge base that is somehow more organized or deeper than that of novices, how is this knowledge selectively and appropriately deployed, often under severe time constraints?

Our gums (gingiva) act as a significant barricade in guarding our teeth and their neighboring support structures. A tiny known fact is that gum disease is the foremost cause of tooth loss in grown persons. Healthy, strong, teeth are reliant on on healthy gums.

If left for a sufficient period of time, (...) bacterial plaque causes hurt to our teeth as well as our gums.

I propose to study one problem for epistemic dependence on experts: how to locate experts on what I will call cognitive islands. Cognitive islands are those domains for knowledge in which expertise is required to evaluate other experts. They exist under two conditions: first, that there is no test for expertise available to the inexpert; and second, that the domain is not linked to another domain with such a test. Cognitive islands are the places where we have the fewest (...) resources for evaluating experts, which makes our expert dependences particularly risky. -/- Some have argued that cognitive islands lead to the complete unusability of expert testimony: that anybody who needs expert advice on a cognitive island will be entirely unable to find it. I argue against this radical form of pessimism, but propose a more moderate alternative. I demonstrate that we have some resources for finding experts on cognitive islands, but that cognitive islands leave us vulnerable to an epistemic trap which I will call runaway echo chambers. In a runaway echo chamber, our inexpertise may lead us to pick out bad experts, which will simply reinforce our mistaken beliefs and sensibilities. (shrink)

In this paper, I will try to answer the question: How are we supposed to assess the expert’s opinion in an argument from the position of an outsider to the specialized field? by placing it in the larger context of the political status of epistemic authority. In order to do this I will first sketch the actual debate around the problem of expertise in a democracy and relate this to the issue of the status of science in society. (...) Secondly, I will review how Douglas Walton’s pragma-dialectical approach offers a practical procedure to assess the expert bias from a nonprofessional’s perspective. Thirdly, I will introduce the problem of group bias using insights from Bohman and Fischer and show how Walton’s solution does not address this specific type of bias. Lastly, I will try proposing a revision of Walton’s solution in order to address this problem. In order to make the explanation more easy to follow I will use a case study concerning the medical expertise in the public debate on second-hand smoke. (shrink)

Expert testimony figures in recent debates over how best to understand the norm of assertion and the domain-specific epistemic expectations placed on testifiers. Cases of experts asserting with only isolated second-hand knowledge (Lackey 2011, 2013) have been used to shed light on whether knowledge is sufficient for epistemically permissible assertion. I argue that relying on such cases of expert testimony introduces several problems concerning how we understand expert knowledge, and the sharing of such knowledge through testimony. Refinements (...) are needed to clarify exactly what principles are being tested by such cases; but once refined, such cases raise more questions than they answer. (shrink)

We sometimes seek expert guidance when we don’t know what to think or do about a problem. In challenging cases concerning medical ethics, we may seek a clinical ethics consultation for guidance.

The widespread practice of ethics consultations raises these questions (...) and more: -/- • What would it take to be a moral expert? • Is anyone a moral expert, and if so, how could a non-expert identify one? • Is it in any way problematic to accept and follow the advice of a moral expert as opposed to coming to moral conclusions on your own? • What should we think and do when moral experts disagree about a practical ethical issue? -/- In what follows, we address these theoretical and practical questions about moral expertise.

It has often been noted that Socratic cross-examination is problematic as a method of inquiry, i.e., as a method for 'acquiring' knowledge. Rarely has it been noticed that there are problems with cross-examination when used for the purposes of 'testing' for knowledge. In the 'Charmides', Socrates commits himself to the following principle: In order to discriminate between the person who knows and the person who does not know the subject matter covered by a particular discipline (technê), one must have mastered (...) that discipline. But if Socrates' disavowals of moral knowledge are sincere, it would seem to follow from this principle that, contrary to what Socrates says in many early dialogues, he cannot successfully test claims to moral expertise through cross-examination. Through an examination of the conditions that Socrates places on knowledge and on mastering a 'technê', I show how this problem can be resolved. (shrink)

Accounts of arguments from expert opinion take it for granted that expert judgments count as (defeasible) evidence for propositions, and so an argument that proceeds from premises about what an expert judges to a conclusion that the expert is probably right is a strong argument. In Mizrahi (2013), I consider a potential justification for this assumption, namely, that expert judgments are significantly more likely to be true than novice judgments, and find it wanting because (...) of empirical evidence suggesting that expert judgments under uncertainty are not significantly more likely to be true than novice judgments or even chance. In this paper, I consider another potential justification for this assumption, namely, that expert judgments are not influenced by the cognitive biases novice judgments are influenced by, and find it wanting, too, because of empirical evidence suggesting that experts are vulnerable to pretty much the same cognitive biases that novices are vulnerable to. If this is correct, then the basic assumption at the core of accounts of arguments from expert opinion, namely, that expert judgments count as (defeasible) evidence for propositions, remains unjustified.

Background: Depression (major depressive disorder) is a common and serious medical illness that negatively affects how you feel, the way you think and how you act. Fortunately, it is also treatable. Depression causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can lead to a variety of emotional and physical problems and can decrease a person’s ability to function at work and at home. Depression affects an estimated one in 15 adults (6.7%) in any given (...) year. And one in six people (16.6%) will experience depression at some time in their life. Depression can strike at any time, but on average, first appears during the late teens to mid-20s. Women are more likely than men to experience depression. Some studies show that one-third of women will experience a major depressive episode in their lifetime. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment and give the appropriate method of treatment through several tips that concern the disease and how to treat it and we will see it through the application on the expert system. Methods: in this paper the design of the proposed Expert System which was produced to help Psychologist in diagnosing depression disease through its symptoms such as: a loss of energy, a change in appetite, sleeping more or less, anxiety, reduced concentration, indecisiveness, restlessness, feelings of worthlessness, guilt or hopelessness and thoughts of self-harm or suicide.

When an agent learns of an expert's credence in a proposition about which they are an expert, the agent should defer to the expert and adopt that credence as their own. This is a popular thought about how agents ought to respond to (ideal) experts. In a Bayesian framework, it is often modelled by endowing the agent with a set of priors that achieves this result. But this model faces a number of challenges, especially when applied to (...) non-ideal agents (who nevertheless interact with ideal experts). I outline these problems, and use them as desiderata for the development of a new model. Taking inspiration from Richard Jeffrey's development of Jeffrey conditioning, I develop a model in which expert reports are taken as exogenous constraints on the agent's posterior probabilities. I show how this model can handle a much wider class of expert reports (for example reports of conditional probabilities), and can be naturally extended to cover propositions for which the agent has no prior.

Two challenges have faced policymakers during the Covid-19 pandemic: First, they must determine the reliability of expert testimony in the face of uncertainty; second, they must determine the relevance of different kinds of expertise with regard to particular decisions.

I contend that the problem of relevance highlights (...) the limited appeal of a thoroughly technocratic society. Value judgments, best realized through democratic processes, are always lurking in the background. (shrink)

This way we intend to show how the sociological explanation of the choice of experts can incorporate its epistemic justification. (shrink)

Background: There is no doubt that strawberry diseases are one of the most important reasons that led to the destruction of strawberry plants and their crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases after a good step for proper and correct treatment.

A perennial problem in social epistemology is the problem of expert testimony, specifically expert testimony regarding scientific issues: for example, while it is important for me to know information pertaining to anthropogenic climate change, vaccine safety, Covid-19, etc., I may lack the scientific background required to determine whether the information I come across is, in fact, true. Without being able to evaluate the science itself, then, I need to find trustworthy expert testifiers to listen to. (...) A major project in social epistemology has thus become determining what the markers of trustworthiness are that laypersons can appeal to in order to identify and acquire information from expert testifiers. At the same time, the ways in which we acquire scientific information has changed significantly, with much of it nowadays being acquired in online environments. While much has been said about the potential pitfalls of seeking information online, little has been said about how the nature of seeking information online should make us think about the problem of expert testimony. Indeed, it seems to be an underlying assumption that good markers of trustworthiness apply equally well when seeking information from expert testifiers in online and offline environments alike, and that the new challenges and opportunities presented by online environments merely affects the methods by which we can acquire evidence of said trustworthiness. Here I argue that in making this assumption one risks failing to account for how unique features of the ways in which we acquire information online affect how we evaluate the trustworthiness of experts. Specifically, I argue for two main claims: first, that the nature of information-seeking online is such that the extent to which information is susceptible to manipulation is a dominant marker of trustworthiness; second, as a result, one will be more likely to seek out a particular kind of expert testifier in online environments, what I call a cooperative as opposed to preemptive expert. The result is that criteria for expert trustworthiness may look significantly different when acquiring information online as opposed to offline. (shrink)

Plant diseases are numerous in the world of agriculture. These diseases cause a lot of trouble to most farmers. Among these common diseases, we single out the diseases that affect the Passion fruit, which is affected by about seven diseases, with different symptoms for each disease. Today, technology is facilitating human life in all areas of life, and among these facilities are expert system, a computer program that uses artificial-intelligence methods to solve problems within a specialized domain that ordinarily (...) requires human expertise. The first expert system was developed in 1965 by Edward Feigen Baum and Joshua Lederberg of Stanford University in California, U.S. Dendral, as their expert system was later known, was designed to analyses chemical compounds. Expert systems now have commercial applications in fields as diverse as medical diagnosis, petroleum engineering, and financial investing and other areas, and with reference to expert systems and their importance to humans, an integrated expert system has been created in the agricultural field that diagnoses Passion diseases using CLIPS Expert System language. The system was used to design and implement the proposed expert system. The system facilitates the diagnosis of Passion -related diseases.

Expert skill in music performance involves an apparent paradox. On stage, expert musicians are required accurately to retrieve information that has been encoded over hours of practice. Yet they must also remain open to the demands of the ever-changing situational contingencies with which they are faced during performance. To further explore this apparent paradox and the way in which it is negotiated by expert musicians, this article profiles theories presented by Roger Chaffin, Hubert Dreyfus and Tony and (...) Helga Noice. For Chaffin, expert skill in music performance relies solely upon overarching mental representations, while, for Dreyfus, such representations are needed only by novices, while experts rely on a more embodied form of coping. Between Chaffin and Dreyfus sit the Noices, who argue that both overarching cognitive structures and embodied processes underlie expert skill. We then present the Applying Intelligence to the Reflexes (AIR) approach?a differently nuanced model of expert skill aligned with the integrative spirit of the Noices? research. The AIR approach suggests that musicians negotiate the apparent paradox of expert skill via a mindedness that allows flexibility of attention during music performance. We offer data from recent doctoral research conducted by the first author of this article to demonstrate at a practical level the usefulness of the AIR approach when attempting to understand the complexities of expert skill in music performance.

The increasing demand for transparency in AI has recently come under scrutiny. The question is often posted in terms of “epistemic double standards”, and whether the standards for transparency in AI ought to be higher than, or equivalent to, our standards for ordinary human reasoners. I agree that the push for increased transparency in AI deserves closer examination, and that comparing these standards to our standards of transparency for other opaque systems is an appropriate starting point. I suggest that a (...) more fruitful exploration of this question will involve a different comparison class. We routinely treat judgments made by highly trained experts in specialized fields as fair or well-grounded even though—by the nature of expert/layperson division of epistemic labor—an expert will not be able to provide an explanation of the reasoning behind these judgments that makes sense to most other people. Regardless, laypeople are thought to be acting reasonably—and ethically—in deferring to the judgments of experts that concern their areas of specialization. I suggest that we reframe our question regarding the appropriate standards of transparency in AI as one that asks when, why, and to what degree it would be ethical to accept opacity in AI. I argue that our epistemic relation to certain opaque AI technology may be relevantly similar to the layperson’s epistemic relation to the expert in certain respects, such that the successful expert/layperson division of epistemic labor can serve as a blueprint for the ethical use of opaque AI.

In times of populist mistrust towards experts, it is important and the aim of the paper to ascertain the rationality of arguments from expert opinion and to reconstruct their rational foundations as well as to determine their limits. The foundational approach chosen is probabilistic. However, there are at least three correct probabilistic reconstructions of such argumentations: statistical inferences, Bayesian updating, and interpretive arguments. To solve this competition problem, the paper proposes a recourse to the arguments' justification strengths achievable (...) in the respective situation. (shrink)

SPECIAL ISSUE ON DISAGREEMENTS: The fact of moral disagreement is often raised as a problem for moral realism. The idea is that disagreement amongst people or communities on moral issues is to be taken as evidence that there are no objective moral facts. While the fact of ‘folk’ moral disagreement has been of interest, the fact of expert moral disagreement, that is, widespread and longstanding disagreement amongst expert moral philosophers, is even more compelling. In this paper, I (...) present three arguments against the anti-realist explanation for widespread and longstanding disagreement amongst expert moral philosophers. Each argument shows the argument from expert disagreement for moral anti-realism, that is, denial of morality’s objectivity, to be in one way or another self-undermining. I conclude that widespread and longstanding disagreement amongst expert moral philosophers is not a problem for moral realism. (shrink)

Artificial intelligence is one of the most rapidly evolving fields today. It is used in the majority of computer science applications nowadays. Expert systems are one of the most valuable types of AI; they are used to deliver predictions and decisions in order to make scientific, medical, and even architectural challenges easier to address; they will eventually take the place of a human expert. Without having to meet with a genuine human specialist, the user will be able to (...) get a precise solution or diagnose to his problem. This study provides an illustration of how computer systems can be used in agriculture. In order to construct an expert system that can forecast a disease based on its symptoms, we chose a Coriander plant and five of its recognized ailments. CLIPS was used to develop the system. This article contains a full summary of the work that has been done. (shrink)

There are many philosophical problems surrounding experts, given the power and status accorded to them in society. We think that what makes someone an expert is having expertise in some skill domain. But what does expertise consist in, and how closely related is expertise to the notion of an expert? Although most of us have acquired several practical skills, few of us have achieved the level of expertise with regard to those skills. So we can be easily misled (...) as to the nature of expertise, since it differs significantly from earlier stages of skill acquisition. Furthermore, this potential for misleading characterizations of skills and expertise leads to philosophers implicitly working with different conceptions of skills. This can interfere with their attempts to solve related problems about experts. In this paper I inquire into the nature of expertise, by drawing on recent psychological research on skill acquisition and expert performance. In addition, I connect this research on expertise to the larger context of psychological research on human cognition, as it will illuminate some of the differing elements of expertise. This allows me to then critique philosophical accounts of expertise, by showing how they make unwarranted assumptions about skills and expertise. Finally, I note the ways in which being credited as an expert can diverge from the possession of expertise itself. This can help us resist some of the power dynamics involved with those deemed to be experts. (shrink)

The study ascertained mathematical problem-solving skills and self-efficacy as correlates of Pre-service NCE Mathematics Teachers’ Performance in South-East, Nigeria. Seven research questions guided the study while seven hypotheses were tested at 0.05 level of significance. Correlation research design was used for the study. The population of the study was 197 pre-service NCE Mathematics teachers in South-East, Nigeria. All the population of 197 was studied as sample because, it is small and manageable. Mathematics Problem-Solving Skill Test (MPSST) and Pre-Service (...) Teachers’ Self-Efficacy Questionnaire (PSTSEQ) were used as instruments for data collection. Both instruments were validated by three experts in science Education while reliabilities of MPSST and PSTSEQ were established using Cronbach Alpha method and coefficient values of 0.82 and 0.80 respectively were obtained which were considered high enough to confirm the instruments as reliable. Data were collected and analyzed using Pearson product moment correlation coefficient. The findings revealed that a high positive and significant relationship existed between mathematical problem-solving skills scores and academic performance scores and between self-efficacy scores and academic performance scores of pre-service NCE mathematics teachers. It was recommended among others that Mathematics lecturers should make conscious effort towards improving the mathematical problem-solving skills and self-efficacy of the pre-service NCE mathematics teachers through modeling, conditioning, and behaviour modification for improved academic performance in Mathematics.

In the last chapter of The Public and its Problems John Dewey outlines the alleged fallacy of "the democratic creed". According to him the fallacy is described as conflating emancipation with the capacity to rule, i.e. the capacity to make policy decisions. His point is that the power to make decisions does not entail a capacity to make good choices. Capable are those in the know, the experts who are "intellectually qualified". The answer to the fallacy is to propose epistocracy: (...) The rule of experts – as Walter Lippman had come close to arguing. But Dewey tries to refute the argument for epistocracy. He rehearses the old platonic wisdom that the harmonious state... (shrink)
