This paper is about a tension between two theses. The first is Value of Evidence: roughly, the thesis that it is always rational for an agent to gather and use cost‐free evidence for making decisions. The second is Rationality of Imprecision: the thesis that an agent can be rationally required to adopt doxastic states that are imprecise, i.e., not representable by a single credence function. While others have noticed this tension, I offer a new diagnosis of it. (...) I show that it arises when an agent with an imprecise doxastic state engages in an unreflective inquiry, an inquiry where they revise their beliefs using an updating rule that doesn't satisfy a weak reflection principle. In such an unreflective inquiry, certain synchronic norms of instrumental rationality can make it instrumentally irrational for an agent to gather and use cost‐free evidence. I then go on to propose a diachronic norm of instrumental rationality that preserves Value of Evidence in unreflective inquiries. This, I suggest, may help us reconcile this thesis with Rationality of Imprecision. (shrink)

In sequential decision problems, an act of learning cost-free evidence might be symptomatic, in the sense that performing this act itself provides evidence about states of the world it does nothing to causally promote. It is well known that orthodox causal decision theory, like its main rival evidential decision theory, may sanction such acts as rationally impermissible. This paper shows that, under plausible assumptions, a minimal version of ratificationist causal decision theory, known as principled ratificationism, fares better in (...) this respect, for it never labels symptomatic acts of learning cost-free evidence as rationally impermissible.

A "symptomatic act" is an act that is evidence for a state that it has no tendency to cause. In this paper I show that when the evidential value of a symptomatic act might influence subsequent choices, causal decision theory may initially recommend against its own use for those subsequent choices. And if one knows that one will nevertheless use causal decision theory to make those subsequent choices, causal decision theory may favor the one-box solution in Newcomb's problem, (...) and may recommend against making cost-free observations. But if one can control one's future choices, then causal decision theory never recommends against cost-free observation. (shrink)

To say that evidence is normative is to say that what evidence one possesses, and how this evidence relates to any proposition, determines which attitude among believing, disbelieving and withholding one ought to take toward this proposition if one deliberates about whether to believe it. It has been suggested by McHugh that this view can be vindicated by resting on the premise that truth is epistemically valuable. In this paper, I modify the strategy sketched by McHugh so (...) as to overcome the initial difficulty that it is unable to vindicate the claim that on counterbalanced evidence with respect to P one ought to conclude deliberation by withholding on P. However, I describe the more serious difficulty that this strategy rests on principles whose acceptance commits one to acknowledging non-evidential reasons for believing. A way to overcome this second difficulty, against the evidentialists who deny this, is to show that we sometimes manage to believe on the basis of non-epistemic considerations. If this is so, one fundamental motivation behind the evidentialist idea that non-epistemic considerations could not enter as reason in deliberation would lose its force. In the second part of this paper I address several strategies proposed in the attempt to show that we sometimes manage to believe on the basis of non-epistemic considerations and show that they all fail. So, I conclude that the strategy inspired by McHugh to ground the normativity of evidence on the value of truth ultimately fails. (shrink)

This paper proposes an extended version of the interventionist account for causal inference in the practical context of biological mechanism research. This paper studies the details of biological mechanism researchers’ practices of assessing the evidential legitimacy of experimental data, arguing why quantity and variety are two important criteria for this assessment. Because of the nature of biological mechanism research, the epistemic values of these two criteria result from the independence both between the causation of data generation and the causation in (...) question and between different interventions, not techniques. The former independence ensures that the interventions in the causation in question are not affected by the causation that is responsible for data generation. The latter independence ensures the reliability of the final mechanisms not only in the empirical but also the formal aspects. This paper first explores how the researchers use quantity to check the effectiveness of interventions, where they at the same time determine the validity of the difference-making revealed by the results of interventions. Then, this paper draws a distinction between experimental interventions and experimental techniques, so that the reliability of mechanisms, as supported by the variety of evidence, can be safely ensured in the probabilistic sense. The latter process is where the researchers establish evidence of the mechanisms connecting the events of interest. By using case studies, this paper proposes to use ‘intervention’ as the fruitful connecting point of literature between evidence and mechanisms. (shrink)

Legal scholarship exploring the nature of evidence and the process of juridical proof has had a complex relationship with formal modeling. As evident in so many fields of knowledge, algorithmic approaches to evidence have the theoretical potential to increase the accuracy of fact finding, a tremendously important goal of the legal system. The hope that knowledge could be formalized within the evidentiary realm generated a spate of articles attempting to put probability theory to this purpose. This literature was (...) both insightful and frustrating. Much light was shed on the legal system, but it also quickly became evident that the tools of probability theory were in many ways ill-constructed for the task. Fundamental incompatibilities between the structure of legal decision making and the extant formal tools were identified, and it became evident that many of the purported explanations of legal phenomena were internally inconsistent. As a consequence, interest in this type of formal modeling declined, and attention was directed toward different kinds of explanations of the phenomena. Perhaps under the influence of a recent trend toward various types of formal modeling in legal scholarship, a recent burst of articles, rather than attempting to explain the macro structure of trials, which was the previous object of interest, attempts to quantify the probative value of various items of evidence in ways consistent with the formal features of various probability theories, and then to study decision making from that perspective. For example, the value of evidence is often purported to be its likelihood ratio, that is, the probability of discovering or receiving the evidence given a hypothesis (e.g., the defendant did it) divided by the probability of discovering or receiving the evidence given the negation of the hypothesis (the defendant didn't do it). Alternatively, the value of evidence is purported (more contextually) to be the information gain it provides, defined as the increase in probability it provides for a hypothesis above the probability of the hypothesis based on the other available evidence. Both conceptions then assume that all of the various probability assessments conform or ought to conform to the dictates of Bayes' theorem (that maintains consistency among such assessments); empirical studies are then done testing the extent to which this is so and proposing how the law can increase the probability that it is so. The general criticisms of using Bayes' theorem as a formal model of juridical proof are well known and were integral to the last wave of interest in formal modeling of the evidentiary process. This paper thus for the most part puts aside that more general issue, and focuses specifically on mathematical modeling of the value of particular items of evidence. The paper demonstrates that formal modeling has only limited value in explaining the value of legal evidence, much more limited than those constructing and discussing the models assume, and thus that the conclusions they draw about the value of evidence are unwarranted. This is done through a discussion of four recent examples that attempt to quantify evidence relating to, respectively, carpet fibers, infidelity, DNA random-match evidence, and character evidence used to impeach a witness. This article thus makes two contributions. First, and most importantly, it is another demonstration of the complex relationship between algorithmic tools and legal decision making. Second, at a minimum it points out serious pitfalls for analytical or empirical studies of juridical proof. (shrink)

We explore the question of whether cost-free uncertain evidence is worth waiting for in advance of making a decision. A classical result in Bayesian decision theory, known as the value of evidence theorem, says that, under certain conditions, when you update your credences by conditionalizing on some cost-free and certain evidence, the subjective expected utility of obtaining this evidence is never less than the subjective expected utility of not obtaining it. We extend this result to (...) a type of update method, a variant of Judea Pearl’s virtual conditionalization, where uncertain evidence is represented as a set of likelihood ratios. Moreover, we argue that focusing on this method rather than on the widely accepted Jeffrey conditionalization enables us to show that, under a fairly plausible assumption, gathering uncertain evidence not only maximizes expected pragmatic utility, but also minimizes expected epistemic disutility.

Evidence-based medicine has always required integration of patient values with ‘best’ clinical evidence. It is widely recognized that scientific practices and discoveries, including those of EBM, are value-laden. But to date, the science of EBM has focused primarily on methods for reducing bias in the evidence, while the role of values in the different aspects of the EBM process has been almost completely ignored.

Evidence-based practice in education involves basing decisions about what to do on evidence about the relative effectiveness of available interventions (e.g. programmes, products, practices). This article considers two influential critiques of evidence-based education (EBE) pertaining to its treatment of values. The ‘general critique’ condemns EBE for excluding values from decisions about what to do in education. The ‘specific critique’ condemns EBE for relying on a deterministic view of causality in education which disregards the complex, value-laden nature (...) of educational contexts. I argue that virtually all versions of EBE escape the general critique, including the dominant intervention-centred approach that relies on experimental research to discover ‘what works’, because the predictions EBE aims to support are only one premise in a broader normative argument. Further, intervention-centred EBE can avoid much of the specific values-based critique because it is consistent with a probabilistic, rather than deterministic, understanding of causality. However, I argue that only a context-centred approach to EBE that relies on evidence about the specific target setting from local sources in addition to evidence from theory and mixed methods research can fully address the specific critique by accommodating critics’ descriptive claims about the nature of educational contexts.

Judges were never bound by law to convict a defendant unless they considered him guilty. Yet, they could be prohibited by law from convicting a person they consider guilty due to the absence of legally prescribed or the presence of legally prohibited evidence.Evaluation of Evidence addresses the question: should the law restrict the freedom of judges in assessing the probative value of evidence in the criminal process? Tracing the treatment of evidence from pre-modern to modern (...) times, Mirjan Damaška argues that there has always been some understanding about rules regarding the use and treatment of evidence, and these rules should not be looked askance as a departure from ideal arrangements. In a time when science and technology have the ability to contribute to factual inquiry, there needs to be acceptance of rules that expand or corroborate evidence produced by our native sensory apparatus.

We call attention to an underappreciated way in which non-epistemic values influence evidence evaluation in science. Our argument draws upon some well-known features of scientific modeling. We show that, when scientific models stand in for background knowledge in Bayesian and other probabilistic methods for evidence evaluation, conclusions can be influenced by the non-epistemic values that shaped the setting of priorities in model development. Moreover, it is often infeasible to correct for this influence. We further suggest that, while this (...) value influence is not particularly prone to the problem of wishful thinking, it could have problematic non-epistemic consequences in some cases. (shrink)

Using a worldwide sample, we examine whether corporate social responsibility performance has an impact on the value of cash holdings. We find that investors assign a higher value to cash held by firms that have a high CSR rating. This result is consistent with the idea that CSR policies are a means for managers to act in the shareholders’ interests by mitigating conflicts with stakeholders. Finally, we reveal that CSR performance has a positive impact on the value (...) of cash holdings only for firms which operate in countries where shareholders are well protected from expropriation by managers and in countries where the institutional quality is high.

It is well known that Bayes’ theorem (with likelihood ratios) can be used to calculate the impact of evidence, such as a ‘match’ of some feature of a person. Typically the feature of interest is the DNA profile, but the method applies in principle to any feature of a person or object, including not just DNA, fingerprints, or footprints, but also more basic features such as skin colour, height, hair colour or even name. Notwithstanding concerns about the extensiveness of (...) databases of such features, a serious challenge to the use of Bayes in such legal contexts is that its standard formulaic representations are not readily understandable to non-statisticians. Attempts to get round this problem usually involve representations based around some variation of an event tree. While this approach works well in explaining the most trivial instance of Bayes’ theorem (involving a single hypothesis and a single piece of evidence) it does not scale up to realistic situations. In particular, even with a single piece of match evidence, if we wish to incorporate the possibility that there are potential errors (both false positives and false negatives) introduced at any stage in the investigative process, matters become very complex. As a result we have observed expert witnesses (in different areas of speciality) routinely ignore the possibility of errors when presenting their evidence. To counter this, we produce what we believe is the first full probabilistic solution of the simple case of generic match evidence incorporating both classes of testing errors. Unfortunately, the resultant event tree solution is too complex for intuitive comprehension. And, crucially, the event tree also fails to represent the causal information that underpins the argument. In contrast, we also present a simple-to-construct graphical Bayesian Network (BN) solution that automatically performs the calculations and may also be intuitively simpler to understand. Although there have been multiple previous applications of BNs for analysing forensic evidence—including very detailed models for the DNA matching problem, these models have not widely penetrated the expert witness community. Nor have they addressed the basic generic match problem incorporating the two types of testing error. Hence we believe our basic BN solution provides an important mechanism for convincing experts—and eventually the legal community—that it is possible to rigorously analyse and communicate the full impact of match evidence on a case, in the presence of possible errors.

Credible and well-functioning governance is crucial for the value creation of firms. Recently, private sectors have undergone substantial changes by focusing on good governance as a tool to enhance value, reputation, and image. The primary features of firms with good governance include greater emphasis on accountability practices, proper implementation of a corporate integrity system, and sound internal controls in place to avoid risk and to ensure policy and procedures that are complied. Government linked companies (GLCs) as the backbone (...) of the Malaysian Government have been harshly criticised for not being able to create value(s) despite receiving high priority in the process of getting government projects. Therefore, this study aims to examine the role of good governance systems, which are reflected through accountability systems, corporate integrity systems, and internal control systems towards value creation of Malaysian GLCs. This study collected primary data based on a set of questionnaire survey among 100 GLCs in Malaysia. Based on the regression analysis, this study found that corporate integrity systems and internal control systems were vital elements in ensuring value creation in GLCs. (shrink)

Ever since environmental ethics began to emerge as a philosophical discipline in the 1970s, one of the most common projects of environmental ethicists has been to formulate theories according to which nature (or some non-human natural entities) possesses intrinsic value. However, from time to time we have seen efforts to refute this project, the claim being that not only are the particular theories suggested flawed, but the very idea of intrinsic value in nature—at least in some allegedly important (...) sense of “intrinsic value”—is in principle indefensible (e.g. Norton 1984; Thompson 1990; Regan 1992; Jamieson 1998). In previous work I have criticized several of these alleged refutations of the view that nature .. (shrink)

The value of varied evidence, I propose, lies in the fact that more varied evidence is less coherent on the assumption of the negation of the hypothesis under consideration than less varied evidence. I contrast my own analysis with several other Bayesian analyses of the value of evidential diversity and show how my account explains cases where it seems intuitively that evidential variety is valuable for confirmation.

The law views with suspicion statistical evidence, even evidence that is probabilistically on a par with direct, individual evidence that the law is in no way suspicious of. But it has proved remarkably hard to either justify this suspicion, or to debunk it. In this paper, we connect the discussion of statistical evidence to broader epistemological discussions of similar phenomena. We highlight Sensitivity – the requirement that a belief be counterfactually sensitive to the truth in a (...) specific way – as a way of epistemically explaining the legal suspicion towards statistical evidence. Still, we do not think of this as a satisfactory vindication of the reluctance to rely on statistical evidence. Knowledge – and Sensitivity, and indeed epistemology in general – are of little, if any, legal value. Instead, we tell an incentive-based story vindicating the suspicion towards statistical evidence. We conclude by showing that the epistemological story and the incentive-based story are closely and interestingly related, and by offering initial thoughts about the role of statistical evidence in morality.

In a recent essay (1995), Andrew Wayne charges that Bayesian attempts to account for the rule that, ceteris paribus, diverse evidence confirms better than narrow evidence are inadequate. I reply to these criticisms and argue that, on the contrary, one of the Bayesian approaches considered by Wayne does an excellent job of explaining why, and under what circumstances, diverse evidence is valuable.

Next SectionEvidence based medicine is rightly at the core of current medicine. If patients and society put trust in medical professional competency, and on the basis of that competency delegate all kinds of responsibilities to the medical profession, medical professionals had better make sure their competency is state of the art medical science. What goes for the ethics of clinical trials goes for the ethics of medicine as a whole: anything that is scientifically doubtful is, other things being equal, ethically (...) unacceptable. This particularly applies to so called orphaned fields of medicine, those areas where medical research is weak and diverse, where financial incentives are lacking, and where the evidence regarding the aetiology and treatment of disease is much less clear than in laboratory and hospital based medicine. Examples of such orphaned fields are physiotherapy, psychotherapy, medical psychology, and occupational health, which investigate complex syndromes such as RSI, whiplash, chronic low back pain, and chronic fatigue syndrome. It appears that the primary ethical problem in this context is the lack of attention to the orphaned fields. Although we agree that this issue deserves more attention as a matter of potential injustice, we want to argue that, in order to do justice to the interplay of heterogeneous factors that is so typical of the orphaned fields, other ethical models than justice are required. We propose the coordination model as a window through which to view the important ethical issues which relate to the communication and interaction of scientists, health care workers, and patients.

It is commonly argued that values “fill the logical gap” of underdetermination of theory by evidence, namely, values affect our choice between two or more theories that fit the same evidence. The underdetermination model, however, does not exhaust the roles values play in evidential reasoning. I introduce WAVE – a novel account of the logical relations between values and evidence. WAVE states that values influence evidential reasoning by adjusting evidential weights. I argue that the weight-adjusting role of (...) values is distinct from their underdetermination gap-filling role. Values adjust weights in three ways. First, values affect our trust in the testimony of others. Second, values influence the evidential thresholds required for justified epistemic judgments. Third, values influence the relative weight of a certain type of evidence within a body of multimodal discordant evidence. WAVE explains, from an epistemic perspective, rather than psychological, how smokers, for example, can find the same evidence about the dangers of smoking less persuasive than non-smokers. WAVE allows for a wider effect of values on our accepted scientific theories and beliefs than the effect for which the underdetermination model allows alone; therefore, science studies scholars must consider WAVE in their research and analysis of evidential case studies.

With twentieth- and twenty-first-century philosophy of science’s unfolding acceptance of the nature of scientific inquiry being value-laden, the persistent worry has been that there are no means for legitimate negotiation of the social or non-epistemic values that enter into science. The rejection of the value-free ideal in science has thereby been coupled with the spectres of indiscriminate relativism and bias in scientific inquiry. I challenge this view in the context of recently expressed concerns regarding Canada's death of (...) class='Hi'>evidence controversy. The worry, raised by Stathis Psillos, is that as constructivist accounts of science demoted the previously secure status of evidence for drawing justified conclusions in science, we were left with no rational delineation between the right and wrong values for science. The implication for the death of evidence controversy is that we may have no rational grounds for claiming that the Canadian Government is wrong to interfere with scientific enterprise. But he does offer another avenue for reaching the conclusion that the wrong social values are directing the current stifling of some sectors of Canadian science. Psillos draws from standpoint epistemologies to devise a salient defence of ‘valuing evidence’ as a universalizable social value. That is, government bodies ought to enable scientific research via adequate funding as well as political non-interference. In this paper, I counter that non-epistemic values can be rationally evaluated and that standpoint epistemology’s universalizable standpoint provides an inadequate framework for negotiating social values in science. Regarding, I draw from the evidence-based medicine debate in philosophy of medicine and from feminist empiricist investigations into the science–values relationship in order to make the argument for empirically driven value arbitration. If social values can be rationally chosen in the context of justification, then we can have grounds for charging the Canadian leadership with being ‘at war with science’. I further argue that my recommended empiricist methodology is preferable to Psillos’s search for universalizable perspectives for negotiating social values in science because the latter method permits little more than the trivial conclusion that evidence is valuable to science.

Traditionally, cognitive values have been thought of as a collective pool of considerations in science that frequently trade against each other. I argue here that a finer-grained account of the value of cognitive values can help reduce such tensions. I separate the values into groups, minimal epistemic criteria, pragmatic considerations, and genuine epistemic assurance, based in part on the distinction between values that describe theories per se and values that describe theory-evidence relationships. This allows us to clarify why (...) these values are central to science and what role they should play, while reducing the tensions among them. (shrink)

In this article, I cast doubt on an apparent truism, namely, that if evidence is available for gathering and use at a negligible cost, then it’s always instrumentally rational for us to gather that evidence and use it for making decisions. Call this ‘value of information’ (VOI). I show that VOI conflicts with two other plausible theses. The first is the view that an agent’s evidence can entail non-trivial propositions about the external world. The second is (...) the view that epistemic rationality requires us to update our credences by conditionalization. These two theses, given some plausible assumptions, make room for rationally biased inquiries where VOI fails. I go on to argue that this is bad news for defenders of VOI. (shrink)

Epistemic peer disagreement raises interesting questions, both in epistemology and in philosophy of science. When is it reasonable to defer to the opinion of others, and when should we hold fast to our original beliefs? What can we learn from the fact that an epistemic peer disagrees with us? A question that has received relatively little attention in these debates is the value of epistemic peer disagreement—can it help us to further epistemic goals, and, if so, how? We investigate (...) this through a recent case in paleoanthropology: the debate on the taxonomic status of Homo floresiensis remains unresolved, with some authors arguing the fossils represent a novel hominin species, and others claiming that they are Homo sapiens with congenital growth disorders. Our examination of this case in the recent history of science provides insights into the value of peer disagreement, indicating that it is especially valuable if one does not straightaway defer to a peer’s conclusions, but nevertheless remains open to a peer’s evidence and arguments.

This paper considers a puzzling conflict between two positions that are each compelling: it is irrational for an agent to pay to avoid `free' evidence before making a decision, and rational agents may have imprecise beliefs and/or desires. Indeed, we show that Good's theorem concerning the invariable choice-worthiness of free evidence does not generalise to the imprecise realm, given the plausible existing decision theories for handling imprecision. A key ingredient in the analysis, and a potential source of controversy, (...) is the general approach taken for resolving sequential decision problems { we make explicit what the key alternatives are and defend our own approach. Furthermore, we endorse a resolution of the aforementioned puzzle { we privilege decision theories that merely permit avoiding free evidence over decision theories for which avoiding free evidence is uniquely admissible. Finally, we situate this particular result about free evidence within the broader `dynamic-coherence' literature. (shrink)

The position of some environmental ethicists that some non-humans have intrinsic value as a mind-independent property is seriously flawed. This is because human beings lack any evidence for this position and hence are unjustified in holding it. For any possible world that is alleged to have this kind of intrinsic value, it is possible to conceive an observationally identical world that lacks intrinsic value. Hence, one is not justified in inferring the intrinsic value of some (...) non-human from any set of observable properties, since that same set of properties could just as well exist in a world that lacks intrinsic value. However, since human beings do not have a faculty of intuition that would allow them to .. (shrink)

Feminist epistemologies consider ways in which gender influences knowledge. In this article, I want to consider a particular kind of feminist empiricism that has been called feminist radical empiricism. I am particularly interested in this view's treatment of values as empirical, and consequently up for revision on the basis of empirical evidence. Proponents of this view cite the fact that it allows us to talk about certain things such as racial and gender equality as objective facts: not just whether (...) we have achieved said equality in our society, but whether we are, in fact, all equal. I will raise the concern that the way in which they model the role of values in epistemology may be a problematic idealization of the open-mindedness of human agents. In some cases, resistance to value-change cannot be diagnosed as a failure to respond adequately to evidence. If so, the strategy of empirically testing our values that some feminist radical empiricists suggest may not be as useful a tool for social change as they think. (shrink)

It is now commonly held that values play a role in scientific judgment, but many arguments for that conclusion are limited. First, many arguments do not show that values are, strictly speaking, indispensable. The role of values could in principle be filled by a random or arbitrary decision. Second, many arguments concern scientific theories and concepts which have obvious practical consequences, thus suggesting or at least leaving open the possibility that abstruse sciences without such a connection could be value-free. (...) Third, many arguments concern the role values play in inferring from evidence, thus taking evidence as given. This paper argues that these limitations do not hold in general. There are values involved in every scientific judgment. They cannot even conceivably be replaced by a coin toss, they arise as much for exotic as for practical sciences, and they are at issue as much for observation as for explicit inference. (shrink)

The Meno problem, asking for the surplus value of knowledge beyond the value of true justified belief, was recently much treated within reliabilist and virtue epistemologies. The answers from formal epistemology, by contrast, are quite poor. This paper attempts to improve the score of formal epistemology by precisely explicating Timothy Williamson's suggestion that ‘present knowledge is less vulnerable than mere present true belief to rational undermining by future evidence’. It does so by combining Nozick's sensitivity analysis of (...) knowledge with Spohn's fact‐asserting epistemic interpretation of conditionals. Accordingly, the surplus value of knowledge lies in a specific kind of stability of knowledge, which differs, though, from that claimed by other so‐called stability analyses of knowledge. (shrink)

Can it be better or worse for a person to exist than not to exist at all? This old and challenging existential question has been raised anew in contemporary moral philosophy, mainly for two reasons. First, traditional “impersonal” ethical theories, such as utilitarianism, have counterintuitive implications in population ethics, for example, the repugnant conclusion. Second, it has seemed evident to many that an outcome can be better than another only if it is better for someone, and that only moral theories (...) that are in this sense “person affecting” can be correct. The implications of this Person-Affecting Restriction will differ radically, however, depending on which answer one gives to the existential question. The negative answer, which we argue against, would make the restriction quite untenable. Hence, many of the problems regarding our moral duties to future generations turn around the issue at hand.

In China, many firms advertise that they follow environmentally friendly practices to cover their true activities, a practice called greenwashing, which can cause the public to doubt the sincerity of greenization messages. In this study, I investigate how the market values greenwashing and further examine whether corporate environmental performance can explain different and asymmetric market reactions to environmentally friendly and unfriendly firms. Using a sample from the Chinese stock market, I provide strong evidence to show that greenwashing is significantly (...) negatively associated with cumulative abnormal returns around the exposure of greenwashing. In addition, corporate environmental performance is significantly positively associated with CAR around the exposure of greenwashing. Furthermore, my findings suggest that corporate environmental performance has two distinct effects on CAR around the exposure of greenwashing: the competitive effect for environmentally friendly firms and the contagious effect for potential environmental wrongdoers, respectively. The results are robust to various sensitivity tests. (shrink)

The main aim of this paper is to introduce the logics of evidence and truth $$LET_{K}^+$$ and $$LET_{F}^+$$ together with sound, complete, and decidable six-valued deterministic semantics for them. These logics extend the logics $$LET_{K}$$ and $$LET_{F}^-$$ with rules of propagation of classicality, which are inferences that express how the classicality operator $${\circ }$$ is transmitted from less complex to more complex sentences, and vice-versa. The six-valued semantics here proposed extends the 4 values of Belnap-Dunn logic with 2 more (...) values that intend to represent (positive and negative) reliable information. A six-valued non-deterministic semantics for $$LET_{K}$$ is obtained by means of Nmatrices based on swap structures, and the six-valued semantics for $$LET_{K}^+$$ is then obtained by imposing restrictions on the semantics of $$LET_{K}$$. These restrictions correspond exactly to the rules of propagation of classicality that extend $$LET_{K}$$. The logic $$LET_{F}^+$$ is obtained as the implication-free fragment of $$LET_{K}^+$$. We also show that the 6 values of $$LET_{K}^+$$ and $$LET_{F}^+$$ define a lattice structure that extends the lattice L4 defined by the Belnap-Dunn four-valued logic with the 2 additional values mentioned above, intuitively interpreted as positive and negative reliable information. Finally, we also show that $$LET_{K}^+$$ is Blok-Pigozzi algebraizable and that its implication-free fragment $$LET_{F}^+$$ coincides with the degree-preserving logic of the involutive Stone algebras.

Science is widely regarded as the most reliable epistemic source of providing knowledge about the world. Policymakers intend to make purposeful changes in the world. The practice of policymakers relying on scientific experts to make informed decisions about which policies to implement is called Evidence Based Policymaking. This thesis provides a perspective from the philosophy of science in order to discuss the justifiability of Evidence Based Policymaking (EBP) with respect to broadly democratic and liberal values. Justifying EBP with (...) broadly democratic and liberal values entails that the practices of EBP promote, or at least are in harmony with, values such as democratic governance and enhancement of people’s freedom and autonomy. Identifying the conditions under which practices of EBP meet such desiderata minimally requires an understanding of how sciences and scientific experts are instrumental in realizing the public’s values, needs, interests, and pursuit of freedom. In order to approach this project, the thesis adopts a philosophical perspective to conceptualize how sciences are supposed to be guided by or promote society’s values, needs, and interests. Specifically, it adopts a perspective from the philosophy of science that focuses on the relationship between science and (societal) values. The kind of philosophy of science perspective on “values in science” that this thesis adopts has two overarching pursuits relevant for the project of the thesis. Firstly, it seeks to inform the debates about which values and non-epistemic considerations are supposed to inform scientific research. For instance, it discusses the proper sources/owners of the non-epistemic desiderata that inform scientific research and the proper social mechanisms to identify these non-epistemic desiderata (e.g. Kourany, 2010; Kitcher, 2011). Second, it offers theories of the non-epistemic values’ proper roles in scientific reasoning and research that specify how their involvement in science does not unduly compromise the epistemic pursuits of science. The values-in-science perspective thereby seeks to balance the instrumental value of science (i.e., its use to pursue certain societal projects and values) with its epistemic authority (i.e., its objectivity, non-dogmatism, and reliability). The thesis advances an understanding of EBP from the perspective of the values in science by addressing issues that come to the fore when EBP is acknowledged as a value-laden practice of informed decision-making.

The current literature on the value of knowledge is marred by two unwarranted presumptions, which together distort the debate and conceal what is perhaps the most basic value of knowledge, as distinct from mere true belief. These presumptions are the Synchronic Presumption, which confines philosophical attention to the present snapshot in time; and the Analytical Presumption, which has people look for the value of knowledge in some kind of warrant. Together these presumptions conceal that the value (...) of knowledge might inhere not in a necessary condition, but simply in a property that most knowledge possesses; and, in particular, that it might inhere, as I argue it does, in a certain property of 'resilience': the tendency to survive misleading counter-evidence over time owing to the subject's being in a position to weight it against evidence already possessed.

I have argued that political values are beliefs informed, more or less well, by the evidence of experience and that, where relevant and well-supported by evidence, the inclusion of political values in scientific theorizing can increase the objectivity of research. The position I endorse has been called the “values-as-evidence” approach. In this essay I respond to three kinds of resistance to this approach, using examples of feminist political values. Solomon questions whether values are beliefs that can be (...) tested, Alcoff argues that even if our values are beliefs that can be tested, testing them might not be desirable because doing so assigns these important values a contingency that weakens their normative force, and Yap argues that the approach is too idealistic in its articulation of the role of evidence in our political deliberations. In response, I discuss the ways that values can be tested, I analyze the evidential strength of feminist values in science, and I argue that the evidence-based nature of these values is neither a weakness nor an idealization. Problems with political values affecting science properly concern the dogmatic ways that evaluative beliefs are sometimes held—a problem that arises with dogmatism toward descriptive beliefs as well. I conclude that scientists, as with the rest of us, ought to adopt a pragmatically-inclined appreciation of the fallible, inductive process by which we gather evidence in support of any of our beliefs, whether they are described as evaluative or descriptive.

There was a time when Greco-Roman culture recognized faith as an indispensable social good. More recently, however, the value of faith has been called into question, particularly in connection with religious commitment. What, if anything, is valuable about faith—in the context of ordinary human relations or as a distinctive stance people might take in relation to God? I approach this question by examining the role that faith talk played both in ancient Jewish and Christian communities and in the larger (...) Greco-Roman culture in which Christian faith talk evolved. I locate the value of faith and faithfulness in the context of relationships involving trust and loyalty and argue that what is most distinctively valuable about faith is the function it plays in sustaining relationships through various kinds of challenges, including through evidentially unfavorable circumstances and significant periods of doubt. In light of this discussion, I set out a view of relational faith and, taking Mother Teresa as an exemplar, argue for two further conclusions. First, faith can play the valuable role that it plays in sustaining relationships even without belief of the salient propositions. Second, in at least some circumstances, in order for faith to play this valuable role in a way that does not require epistemic opinions that fail to fit one’s evidence, it is important that faith does not require such belief.

Proponents of evidence-based policy (EBP) call for public policy to be informed by high-quality evidence from randomized controlled trials. This methodological preference aims to promote several epistemic values, e.g. rigor, unbiasedness, precision, and the ability to obtain causal conclusions. I argue that there is a trade-off between these epistemic values and several non-epistemic, moral and political values. This is because the evidence afforded by preferred EBP methods is differentially useful for pursuing different moral and political values. I (...) expand on how this challenges ideals of value-freedom and -neutrality in EBP, and offer suggestions for how EBP methodology might be revised. (shrink)

We explore the relationship between corporate sustainability, reputation, and firm value by asking whether signaling sustainability leadership through membership on a recognized sustainability index is value generating. Increasingly, stakeholders are demanding that firms demonstrate their commitment to sustainability. One signal that companies can send to stakeholders to indicate that they are sustainability leaders is membership on a recognized “best in class” sustainability index. This article explores both the short-term and the intermediary impact on North American firms of being (...) included or removed from the Dow Jones Sustainability World Index (DJSI). Our results provide evidence that being added to the DJSI results in a sustained increase in a firm’s share price, suggesting that the benefits of being included on the DJSI outweigh the costs associated with applying. This article also notes a temporary decrease in the value of firms for the first 10 days after their removal from the DJSI; however, this effect is eliminated within the next ten trading days.

A frequent criticism of the neuroscientific approach to consciousness is that its theories describe only 'correlates' or 'analogues' of consciousness, and so fail to address the nature of consciousness itself. Despite its apparent logical simplicity, this criticism in fact relies on some substantive assumptions about the nature and evolution of scientific explanations. In particular, it is usually assumed that, in expressing correlations, neural correlate of consciousness (NCC) theories must fail to capture the causal structure relating brain and mind. Drawing on (...) work in the history and philosophy of science, I argue that this assumption - along with the related claim that even a correct NCC theory would fail to explain consciousness - is grounded in an inadequate conception of the way in which scientific explanations develop. Examination of parallel developments in 20th century biology reveals that, under the right circumstances, seemingly crude correspondences can play an essential role in scientific discovery and can sometimes become central to our everyday understanding of the phenomena in question. A proper understanding of this process clarifies the value of NCC theories and sheds light on the standards by which they should be evaluated. In closing, I describe two specific criteria for evaluating NCC proposals: intertheoretic bridge potential and detailed mapping. (shrink)

Since its introduction just over two decades ago, evidence-based medicine (EBM) has come to dominate medical practice, teaching, and policy. There are a growing number of textbooks, journals, and websites dedicated to EBM research, teaching, and evidence dissemination. EBM was most recently defined as a method that integrates best research evidence with clinical expertise and patient values and circumstances in the treatment of patients. There have been debates throughout the early 21st century about what counts as good (...) research evidence between EBM proponents and philosophical critics and even within the EBM community itself. Similar controversy arises about the relative worth of patient values and clinical expertise (and how these can be integrated). EBM has also evolved in ways that have come under scrutiny. Specifically, policymakers have used EBM research methodology to increase the relative importance of clinical guidelines that some clinicians have argued are tyrannical. Philosophers have addressed all of these controversies, and with very few exceptions have been critical of EBM. In addition most philosophical attention has been on the epistemic role of Randomization and evidence hierarchies, with relatively little attention being paid to the role of Diagnosis, expertise, patient values, and Systematic Reviews within EBM.

In a crisis, managers are confronted with a dilemma between their ethical responsibility to respond to victims and their fiduciary responsibility to protect shareholder value. In this study, we use a unique and comprehensive dataset of 223 non-financial crises between 1983 and 2013 to investigate how corporate apologies affect stock prices. Our empirical evidence shows that the stock price response from apologizing depends on the firm’s level of responsibility for the crisis. We find that to protect shareholder (...) class='Hi'>value, management needs to match its formal response strategy with the degree of its responsibility for the crisis. Further, failing to match the proper response is harmful to shareholders: Both apologizing when the firm is not directly responsible for the crisis and failing to apologize when the firm is directly responsible reduce shareholder wealth. However, apologizing for a crisis when the firm is directly responsible mitigates losses to shareholder value that arise because of the crisis, as does refraining from apologizing when the firm is not directly responsible.

Objective:To describe the professional values of the nurse lectures according to 241 nursing students, who participated voluntarily, in three different universities of Bogotá.Methodology:This is a quantitative, descriptive cross-sectional study that applied the Nurses Professional Values Scale—permission secured—Spanish; three dimensions of values were applied: ethics, commitment, and professional knowledge.Ethical consideration:Project had ethical review and approval from an ethics committee and participants were given information sheets to read before they agreed to participate in the project.Findings:It was concluded that nursing students, in general, (...) do perceive these values in their professors, and they give priority to the dimension of ethics, followed by the knowledge dimension, and finally, commitment.Discussion:It is evident that professional values are transmitted by professors and students place importance to such values. Values related to the other’s care are paramount in nursing training in Colombia as well as in other countries.Conclusion:It was found that participating students observed professors directly in relation to values focused on direct patient care, respect for privacy, respect for life, while matters related to professional improvement, participation in unions were not actually analyzed may be due to poor promotion activities and unions during undergraduate studies. The results obtained are primary approach to the study of values related to nursing, a topic which needs to be researched, something vital to all the country offering nursing training programs.
