This chapter focuses on one of the common fallacies in Western philosophy called the suppressed evidence. This fallacy is as simple as it seems: one commits the fallacy when one presents evidence or an argument for a position but leaves out (or suppresses) relevant evidence that would weaken or show false one's conclusion. Suppression of evidence is commonly found in the (mis)presentation of statistics. Suppression of evidence is most common among conspiracy theorists. The fallacy (...) of suppressing the evidence can come from left, right, or center. According to The Skeptics Dictionary, scientists sometimes do it, reporters do it, and pretty much everybody does it now and again. It is an extremely effective way to make one's argument appear stronger than it is. But those interested in the truth should always present all the evidence they can, regardless of whether it hurts or hinders what they want to believe. (shrink)

Analysis of the U.S., Canadian and English approaches to excluding illegally obtained real evidence, which passes the threshold test of authenticity, probative value and relevance, reveals various ways in which poisoned truths are treated in criminal legal systems. A person who has no interaction with the criminal legal system may of course be considerably sympathetic to the English rule which attempts always to reveal the immediate truth. For if one considers only an individual criminal case, the English rule certainlyappears (...) to value truth above all else. However, a contextual analysis makes it clear that there is a systemic effect in always revealing the truth that may result in fewer incidents of the truth being revealed in the future than if the immediate truth were suppressed in a particular case. The U.S. and Canadian exclusionary rules recognize the systemic harm of automatically revealing all truths the moment the truths become apparent. While the U.S. courts have had trouble agreeing on the rationale for excluding illegally obtained real evidence, they have come up with a rule which in the end balances the immediate harm of exclusion of the truth and the systemic harm of its inclusion. The U.S. rule is also very predictable, clearly setting out when a future truth is threatened by revealing an immediate truth. The Canadian rule is in the early stages of development, and, while there is a clearly stated rationale that seeks a justice of truth, it is not sufficiently concrete to allow one to predict when the rationale of a justice of truth will be achieved. In the final analysis, and in contrast to the English exclusionary rule, both the Canadian and U.S. rules address thesystemic harm of always including illegally obtained real evidence. (shrink)

Nurses in Ghana believe that training, practise, practitioner and policy reforms are required for total nursing profession reform to be effective. Their views for role reformation in the nursing profession, which is currently needed, are not only academic but also clinically relevant in the pursuit of health equity and quality nursing care. We explored and described nurses’ views on their roles in the profession using data collected from 24 professional nurses in three regional hospitals in Ghana. Using an inductive (...) descriptive qualitative design, data were gathered and analysed using a qualitative content analysis to describe the views of the nurses. Four major themes, namely practise reforms, practitioner reforms, training reforms and policy reforms have emerged in relation to role reformation in the nursing profession. Three strategic areas, practitioner attitudes, new training modalities and policy realignment, must be reviewed and remodelled for better positioning of the nursing profession before its entire role reformation.

Humans, unlike other animals, are equipped with a powerful brain that permits conscious awareness and reflection. A growing trend in psychological science has questioned the benefits of consciousness, however. Testing a hypothesis advanced by [Lieberman, M. D., Gaunt, R., Gilbert, D. T., & Trope, Y. . Reflection and reflexion: A social cognitive neuroscience approach to attributional inference. Advances in Experimental Social Psychology, 34, 199–249], four studies suggested that the conscious, reflective processing system is vital for logical reasoning. Substantial decrements in (...) logical reasoning were found when a cognitive load manipulation preoccupied conscious processing, while hampering the nonconscious system with consciously suppressed thoughts failed to impair reasoning . Nonconscious activation of the idea of logical reasoning increased the activation of logic-relevant concepts, but failed to improve logical reasoning performance unless the logical conclusions were largely intuitive and thus not reliant on logical reasoning . Meanwhile, stimulating the conscious goal of reasoning well led to improvements in reasoning performance . These findings offer evidence that logical reasoning is aided by the conscious, reflective processing system. (shrink)

S CIENTISTS often claim that an experiment or observation tests certain hypotheses within a complex theory but not others. Relativity theorists, for example, are unanimous in the judgment that measurements of the gravitational red shift do not test the field equations of general relativity; psychoanalysts sometimes complain that experimental tests of Freudian theory are at best tests of rather peripheral hypotheses; astronomers do not regard observations of the positions of a single planet as a test of Kepler's third law, even (...) though those observations may test Kepler's first and second laws. Observations are regarded as relevant to some hypotheses in a theory but not relevant to others in that same theory. There is another kind of scientific judgment that may or may not be related to such judgments of relevance: determinations of the accuracy of the predictions of some theories are not held to provide tests of those theories, or, at least, positive results are not held to support or confirm the theories in question. There are, for example, special relativistic theories of gravity that predict the same phenomena as does general relativity, yet the theories are regarded as.. (shrink)

There has been increased attention on how scientific communities should respond to spurious dissent. One proposed method is to hide such dissent by preventing its publication. To investigate this, I computationally model the epistemic effects of hiding dissenting evidence on scientific communities. I find that it is typically epistemically harmful to hide dissent, even when there exists an agent purposefully producing biased dissent. However, hiding dissent also allows for quicker correct epistemic consensus among scientists. Quicker consensus may be important (...) when policy decisions must be made quickly, such as during a pandemic, suggesting times when hiding dissent may be useful. (shrink)

This study examines whether religiosity is associated with the valuation multiples investors assign to fair-valued assets that are susceptible to managerial bias. Using a sample of U.S. banking firms, I find that the value relevance of such assets is higher for firms located in more religious counties than it is for firms located in less religious counties. Moreover, I find that this result is more consistent with the ethicality trait than the risk aversion trait of more religious individuals. Additional tests (...) show that the positive association between religiosity and value relevance of fair-valued assets is limited to firms with high fair value exposure, and it is stronger for firms with lower audit quality, lower institutional ownership, and lower analyst following. The results of this study suggest that investors perceive the role played by religiosity, in particular ethicality, in curbing managerial accounting biases and price accounting estimates accordingly.

The purpose of this paper is to show whether the two crucial dimensions used for assessing the quality of argumentation, argument-as-a-product (argument structure) and argument-as-a-process (relevance), are interrelated, and how they can be used to assess the effect of argumentative mode on students’ arguments. To this purpose, a twofold coding scheme will be developed, aimed at capturing: a) the argumentative function of evidence use and b) the dialogical relevance of evidence use. A study will be described in which (...) students’ use of evidence is elicited in two distinct argumentative modes (dialogical vs. non-dialogical). According to the results, in the dialogical mode students tended to use evidence in a more sophisticated way from both argument evaluation perspectives. (shrink)

How can philosophy of science be of more practical use? One thing we can do is provide practicable advice about how to determine when one empirical claim is relevant to the truth of another; i.e., about evidential relevance. This matters especially for evidence-based policy, where advice is thin—and misleading—about how to tell what counts as evidence for policy effectiveness. This paper argues that good efficacy results (as in randomized controlled trials), which are all the rage now, are (...) only a very small part of the story. To tell what facts are relevant for judging policy effectiveness, we need to construct causal scenarios about will happen when the policy is implemented. (shrink)

Financial conflicts of interest in medical research foster deviations from research standards and evidentially lead to the suppression of research findings that are at odds with commercial interests of pharmaceutical companies. Questionable research practices prevent data from being created, made available, or given suitable recognition. They run counter to codified principles of responsible conduct of research, such as honesty, openness or respect for the law. Resulting in ignorance, misrepresentation and suspension of scientific self-correction, suppression of medical evidence in its (...) various forms is both a threat to the epistemic and the moral integrity of medical science. This paper discusses an example of the suppression of medical evidence in recent influenza research and develops a conceptual framework for the description and assessment of questionable research practices applied in research and publication processes to suppress evidence.

The concepts of supportive evidence and of relevant evidence seem very closely related to each other. Supportive evidence is clearly always relevant as well. But must relevant evidence be defined as evidence which is either supportive or weakeking? In an explicit or implicit manner, this is indeed the position of many philosophers. The paradox of ideal evidence, however, shows us that this is to restrictive. Besides increasing or decreasing the probability attached (...) to some hypothesis, evidence can alter or interact with the background assumptions underlying the hypothesis.In most circumstances, the (post hoc) relevance of evidence can indeed be judged by its effect on the confidence one attaches to hypotheses. Occasionally, as in the circumstances described by Example I, and more generally called “the Paradox of Ideal Evidence”, the relevance of evidence to an hypothesis can only be understood by appeal to a broader sense.

This essay focuses on conceptual engineers who aim to improve other people's patterns of inference and attention by shaping their concepts. Such conceptual engineers sometimes engage in a form of epistemic paternalism that I call paternalistic cognitive engineering: instead of explicitly persuading, informing and educating others, the engineers non-consultatively rely on assumptions about the target agents’ cognitive systems to improve their belief forming. The target agents could reasonably regard such benevolent exercises of control as violating their sovereignty over their own (...) belief formation. This is a pro tanto reason against such engineering. In addition to the relevant projects of conceptual engineering, paternalistic cognitive engineering plausibly includes certain kinds of nudging and evidence suppression. I distinguish the sovereignty-based concern from other ethical worries about conceptual engineering and discuss how one might justify the relevant conceptual engineering projects despite the sovereignty-based reason against them.

It is widely assumed that it is the anti-realist who stakes his case on evidence from the history of science. I argue that realists have failed to recognize the need to collect evidence from the history of science to support their methodological claims, and anti-realists do not rely on evidence from the history of science to the extent that many suggest.

Jackendoff (2002) argues that grammatically relevant and irrelevant components of meaning do not occupy distinct levels of the semantic system. However, neuropsychological studies have found that the two components doubly dissociate in brain-damaged subjects, suggesting that they are in fact segregated. Neural regionalization of these multidimensional semantic subsystems might take place during language development.

Predictable somatosensory feedback leads to a reduction in tactile sensitivity. This phenomenon, called tactile suppression, relies on a mechanism that uses an efference copy of motor commands to help select relevant aspects of incoming sensory signals. We investigated whether tactile suppression is modulated by the task-relevancy of the predicted consequences of movement and the intensity of related somatosensory feedback signals. Participants reached to a target region in the air in front of a screen; visual or tactile feedback indicated the (...) reach was successful. Furthermore, tactile feedback intensity varied across two groups of participants. We measured tactile suppression by comparing detection thresholds for a probing vibration applied to the finger either early or late during reach and at rest. As expected, we found an overall decrease in late-reach suppression, as no touch was involved at the end of the reach. We observed an increase in the degree of tactile suppression when strong tactile feedback was given at the end of the reach, compared to when weak tactile feedback or visual feedback was given. Our results suggest that the extent of tactile suppression can be adapted to different demands of somatosensory processing. Downregulation of this mechanism is invoked only when the consequences of missing a weak movement sequence are severe for the task. The decisive factor for the presence of tactile suppression seems not to be the predicted action effect as such, but the need to detect and process anticipated feedback signals occurring during movement.

If we assume that Christian faith involves a propositional component whose content is historical, then the question arises as to whether Christian faith must be based on historical evidence, at least in part. One of Kierkegaard’s pseudonyms, Johannes Climacus, argues in Philosophical Fragments that though faith does indeed have such an historical component, it does not depend on evidence, but rather on a first-hand experience of Jesus for which historical records serve only as an occasion. I argue that (...) Climacus’ accountis coherent, and that on such a view historical evidence is not sufficient for faith for anyone. However, in contrast to Climacus, I argue that evidence might still be valuable and even necessary for some people. The resulting danger that the decision about faith might become a question for scholarship is best met, not by insulating faith from historical scholarship, but by recognizing the ability of faith to supply a context in which the evidence available is sufficient.

Approaches relying on fair procedures rather than substantive principles have been proposed for answering dilemmas in medical ethics and health policy. These dilemmas generally involve two questions: the epistemological (factual) question of which benefits an intervention will have, and the ethical (value) question of how to distribute those benefits. This article focuses on the potential of fair procedures to help address epistemological and factual questions in medicine, using the debate over antidepressant efficacy as a test case. In doing so, it (...) employs concepts from social epistemology such as testimonial injustice (bias resulting from the exclusion of evidence) and hermeneutical injustice (bias resulting from a prevailing discussion framework’s conceptual limitations). This article also explores the relevance of scientific consensus to determinations regarding medical evidence. (shrink)

Reducing inequalities in health and the determinants of health is a widely acknowledged health policy goal, and methods for measuring inequalities and inequities in health are well developed. Yet, the evidence base is weak for how to achieve these goals. There is a lack of high-quality randomised controlled trials reporting impact on the distribution of health and non-health benefits and lack of methodological rigour in how to design, power, measure, analyse and interpret distributional impact in RCTs. Our overarching aim (...) in this paper is to contribute to the emerging effort to improve transparency and coherence in the theoretical and conceptual basis for RCTs on effective interventions to reduce health inequity. We endeavour to achieve this aim by pursuing two more specific objectives. First, we propose an overview of three broader health equity frameworks and clarify their implications for the measurement of health inequality in RCTs. Second, we seek to clarify the relationship between theory and translational challenges that researchers would need to attend to, in order to ensure that equity-relevant RCTs are coherently grounded in theory.

The EEG and MEG studies cited in the target article found reduced gamma band power following pseudowords in comparison with words. Pulvermüller interprets this power difference in terms of reverberating lexical cell assemblies. An alternative interpretation in terms of latency jitter in the gamma band following pseudowords is proposed that does not appeal to lexical cell assemblies.

Starting with Jaakko Hintikka’s seminal work, epistemic logic has now grown up to a huge academic industry. When we look back to its history, however, there is a practical paradox. While Hintikka’s original purpose was to facilitate epistemological discussion, most subsequent work of epistemic logic has been done outside of philosophy, and has been ignored by most mainstream epistemologists. At the current point, one might naturally wonder, does epistemic logic still have something to do with epistemology? Along with Hintikka and (...) a growing number of formal epistemologists, we believe the answer is “yes”. Contemporary epistemology has largely focused on the goal of providing an analysis of knowledge and an answer to skepticism. To avoid skepticism, many epistemologists prefer to define knowledge in terms of evidence and relevant alternatives. A typical saying is that “in order to know that p, one only needs evidence to eliminate all relevant alternatives, rather than all alternatives”. We see such a project as perfectly congenial to the spirit of Hintikka’s epistemic logic. In this paper, we propose an epistemic logic to deal with evidence and relevant alternatives explicitly, and extend EREL to its dynamic version to investigate how different notions of knowledge behavior with the decrease and increase of relevant alternatives. To illustrate its philosophical application, we provide a new formalization of the so called factivity problem of epistemic contextualism. We conclude with some remarks on further developments of our framework. (shrink)

This article empirically examines how the performance of Indian manufacturing corporations is affected by corporate governance practices. The study has used panel data comprising of 76 manufacturing companies listed in BSE, for a consecutive six-year period, from 2015-2016 to 2020-2021. The study has applied panel data regression model to enquire the impact of ownership structure variables; and also board composition variables on firm performance using Tobin's Q and ROA. The findings reveal that ownership structure variables, board size and multiplicity of (...) the board positively affect both ROA and Tobin's Q. While independent board and women director show positive effect on Tobin's Q, the CEO-duality is negatively associated with Tobin's Q. The study suggests policymakers to enhance the multiplicity of directors and gender diversity, to maintain the right proportion of board independency, and to increase the size of board. Policymakers may also restrict the CEO to play dual role.Keywordsboard composition, ownership structure, CEO-duality, Tobin's Q. (shrink)

Key Words mental control, intrusive thought, rebound effect, ironic processes Abstract Although thought suppression is a popular form of mental control, research has indicated that it can be counterproductive, helping assure the very state of mind one had hoped to avoid. This chapter reviews the research on suppression, which spans a wide range of domains, including emotions, memory, interpersonal processes, psychophysiological reactions, and psychopathology. The chapter considers the relevant methodological and theoretical issues and suggests directions for future research.
