The title of this symposium, “Formal Simplicity as a Weight in the Acceptability of Scientific Theories,” to some people might seem to suggest that we are to be making positive proposals about how the concept of simplicity could be defined for formalized languages, defined so as to figure in a formalized theory of confirmation. I must confess at the start that I do not have any such ambitious object in view. I now feel, indeed, that premature formalizations have little power (...) to illuminate the philosophically interesting questions which cluster round the problem of the role of simplicity in scientific thinking. So in this short paper I wish merely to present some elementary considerations, not very novel ones, concerning the role which simplicity seems to me to play in our non-demonstrative reasoning about matters of empirical fact. Although many writers have sought to analyze the logical character of such reasoning, little unanimity has been attained in their over-all views; thus it is that though the considerations which I wish to present are elementary, they are not wholly uncontroversial. But because these matters are elementary in nature, I do feel it appropriate in discussing them to use homely examples of uncomplicated kinds, rather than elaborate examples drawn from the more sophisticated reaches of scientific theory; in doing so, I am taking it for granted that scientific inference as regards its logical character is fundamentally a refinement of everyday thinking, rather than a procedure of some essentially different nature.

It is argued that we need a richer version of Bayesian decision theory, admitting both subjective and objective probabilities and providing rational criteria for choice of our prior probabilities. We also need a theory of tentative acceptance of empirical hypotheses. There is a discussion of subjective and of objective probabilities and of the relationship between them, as well as a discussion of the criteria used in choosing our prior probabilities, such as the principles of indifference and of maximum (...) entropy, and the simplicity ranking of alternative hypotheses.

This paper takes part in the methodological debate concerning the nature and the justification of hypotheses about computational systems in software engineering by providing an epistemological analysis of Software Testing, the practice of observing the programs’ executions to examine whether they fulfil software requirements. Property specifications articulating such requirements are shown to involve falsifiable hypotheses about software systems that are evaluated by means of tests which are likely to falsify those hypotheses. Software Reliability metrics, used to measure (...) the growth of probability that given failures will occur at specified times as new executions are observed, is shown to involve a Bayesian confirmation of falsifiable hypotheses on programs. Coverage criteria, used to select those input values with which the system under test is to be launched, are understood as theory-laden principles guiding software tests, here compared to scientific experiments. Redundant computations, fault seeding models and formal methods used in software engineering to evaluate test results are taken to be instantiations of some epistemological strategies used in scientific experiments to distinguish between valid and non-valid experimental outcomes. The final part of the paper explores the problem, advanced in the context of the philosophy of technology, of defining the epistemological status of software engineering by conceiving it as a scientifically attested technology.

According to van Fraassen's constructive empiricism, the epistemological aim of scientific theories is "to save the phenomena". Theories which achieve this aim are said to be empirically adequate. In an earlier paper a likelihood analysis of the empirical adequacy of simple statistical hypotheses was given. The present paper extends that likelihood analysis of empirical adequacy to composite statistical hypotheses. It is argued that for composite hypotheses the notion of likelihood is ambiguous. This ambiguity leads to (...) a distinction between predictive adequacy, based upon a prior likelihood function, and descriptive adequacy, based upon a posterior likelihood function. (shrink)

Proponents of evolutionary debunking arguments aim to show that certain genealogical explanations of our moral faculties, if true, undermine our claim to moral knowledge. Criticisms of these arguments generally take the debunker’s genealogical explanation for granted. The task of the anti-debunker is thought to be that of reconciling the truth of this hypothesis with moral knowledge. In this paper, I shift the critical focus instead to the debunker’s empirical hypothesis and argue that the skeptical strength of an evolutionary debunking (...) argument is dependent upon the evidence for that hypothesis—evidence which, upon further inspection, proves far from compelling. Following that, however, I suggest that the same considerations which spell trouble for the empirical hypotheses of traditional debunking arguments can also be taken to give rise to an alternative—and better supported—style of debunking argument.

The possibility of empirical test is discussed with respect to three issues: (1) What is the ontological relationship between consciousness and the brain/physical world? (2) What physical characteristics are associated with the mind/brain interface? (3) Can consciousness act on the brain independently of any brain process?

Reconstructing the evolution of cognition requires maximal extraction of information from very sparse data. The role that archaeology plays in this process is important, but strong empirical tests of plausible hypotheses are absolutely critical. Quantitative measures of symmetry must be devised, a much deeper understanding of nonhuman primate spatial cognition is needed, and a better understanding of brain/behavior relationships across species is necessary to properly ground these hypotheses.

A number of differences between the dreams of schizophrenia patients and those of healthy participants have been linked to changes in waking life that schizophrenia may cause. This way, the “continuity hypothesis” has become a standard way to relate dreaming and waking experiences in schizophrenia. Nevertheless, some of the findings in dream literature are not compatible with the continuity hypothesis and suggest some other ways how dream content and waking experiences could interact. Conceptually, the continuity hypothesis could be sharpened into (...) the “waking-to-dreaming” and the “dreaming-to-waking” hypotheses, whereas a less explored type of “discontinuity” could embrace the “compensated waking” and the “compensated dreaming” hypotheses. A careful consideration and empirical testing of each of those hypotheses may reveal a multiplicity of the ways how dreaming and waking life interact in schizophrenia. (shrink)

Are there things that are objectively right, wrong, good, bad, etc.: moral properties that are had independently of what we ourselves, our culture, God or any other subjects think about them? Philosophers have traditionally addressed this question from the “armchair.” In recent years, however, more and more participants of the debate have begun to appeal to evidence from science as well. This thesis examines such novel approaches. In particular, it asks what the empirical sciences can contribute to the moral (...) realism/anti-realism debate. My first aim is to show that it is possible for scientific evidence to bear on the question of the existence of objective moral properties. To see whether such contributions are also likely, I will then consider various prominent particular realist and anti-realist arguments: arguments based on hypotheses about ordinary people’s moral experience, the prevalence and persistence of moral disagreement, the evolution of morality, the relation of moral judgements to emotions, and the projection of values. If true, some of these empirical hypotheses would have metaethical implications. The problem with the arguments is, however, that the available scientific evidence does not support, or even contradicts these hypotheses. Only in ways other than have been suggested so far does the evidence considered in this thesis allow for a substantial metaethical conclusion. Finally, I will show that the relation between the empirical sciences and the question of the reality of moral values is actually much closer than commonly assumed. Not only do scientific hypotheses bear on metaethics, metaethical issues bear on the investigation of scientific hypotheses about morality as well. In order to further increase our understanding of what morality is, philosophers and scientists should therefore join forces and work together more closely than they have done so far. (shrink)

Critics of Laudan's normative naturalism have questioned whether methodological rules can be regarded as empirical hypotheses about relations between means and ends. Drawing on Laudan's defense that rules of method are contingent on assumptions about the world, I argue that even if such rules can be shown to be analytic in principle, in practice the warrant for such rules will be empirical. Laudan's naturalism, however, acquires normative force only by construing both methods and epistemic goals as instrumental (...) to practical concerns, and issues only in context-specific and not general methodological principles.

The cognitive science of religions’ By-Product Theory contends that much religious thought and behavior can be explained in terms of the cultural activation of maturationally natural cognitive systems. Those systems address fundamental problems of human survival, encompassing such capacities as hazard precautions, agency detection, language processing, and theory of mind. Across cultures they typically arise effortlessly and unconsciously during early childhood. They are not taught and appear independent of general intelligence. Theory of mind undergirds an instantaneous and automatic intuitive understanding (...) of minds, mental representations, and their implications for agents’ actions. By-Product theorists hypothesize about a social cognition content bias, holding that mentalizing capacities inform participants’ implicit understanding of religious representations of agents with counter-intuitive properties. That hypothesis, in combination with Baron-Cohen’s account of Autistic Spectrum Disorder in terms of diminished theory of mind capacities, suggests an impaired religious understanding hypothesis. It proposes that people with ASD have substantial limitations in intuitive understanding of and creative inferences from such representations. Norenzayan argues for a mind-blind atheism hypothesis, which asserts that the truth of these first two hypotheses suggests that people with ASD have an increased probability, compared to the general population, of being atheists. Numerous empirical studies have explored these three hypotheses’ merits. After carefully pondering distinctions between intuitive versus reflective mentalizing and between explicit versus implicit measures and affective versus cognitive measures of mentalizing, the available empirical evidence provides substantial support for the first two hypotheses and non-trivial support for the third.

Are there objective moral truths, i.e. things that are morally right, wrong, good, or bad independently of what anybody thinks about them? To answer this question more and more scholars have recently turned to evidence from psychology, neuroscience, cultural anthropology, and evolutionary biology. This book investigates this novel scientific approach in a comprehensive, empirically-focused, and partly meta-theoretical way. It suggests that while it is possible for the empirical sciences to contribute to the moral realism/anti-realism debate, most arguments that have (...) so far been proposed fail (because they misrepresent, cherry-pick, or overlook the invalidity of (parts of) the available scientific evidence). The book’s main chapters address five prominent science-based arguments for or against the existence of objective moral truths: the argument from moral disagreement, the evolutionary debunking argument, the sentimentalist argument, the presumptive argument, and the projectivist argument. Thomas Pölzler investigates in which sense the underlying empirical hypotheses would have to be true in order for these arguments to work, and then shows how the available scientific evidence fails to support them. Finally, he makes suggestions as to how to test these hypotheses in a more valid way. Moral Reality and the Empirical Sciences is an important contribution to the moral realism/anti-realism debate that will appeal to philosophers and scientists interested in moral psychology and metaethics.

A proposed empirical criterion for task susceptibility to introspective awareness distinguishes cognitive processes of which one cannot be aware from those of which one can be aware. The empirical criterion for task susceptibility to awareness effects proposes that there are tasks which cannot be affected by awareness of the rules constituting the tasks. These criteria were applied to research programmes in rule-learning in which past studies in the area of learning without awareness were included as well as current (...) research in implicit learning. The principal question addressed in these studies is whether or not rule-learning can occur without awareness. An historical review showed that rule-learning occurred in tasks which were both susceptible and insusceptible to introspective awareness and to awareness effects. Accordingly, it has been proposed that rather than attempt to decide theoretically and empirically between the opposing hypotheses—that of “cognitive learning” on the one hand, which assumes that awareness is a necessary condition for rule-learning, and that of “automatic learning” on the other, which assumes direct, automatic and unconscious processes—efforts should rather be directed toward developing a theoretical approach which is based on both conscious and unconscious processes. However, an approach of this kind encounters severe problems, such as the generation of contradictory predictions, which result from the employment of several incongruent and irreconcilable models of explanation. The criteria for task susceptibility offer a way out of these difficulties. (shrink)

Graphical AbstractThe fungus Neurospora comprises a novel model for testing hypotheses involving the role of sex and reproduction in eukaryotic genome evolution. Its variation in reproductive mode, lack of sex-specific genotypes, availability of phylogenetic species, and young sex-regulating chromosomes make research in this genus complementary to animal and plant models.

In Chapter I, I discuss Buchdahl’s view that the possibility of empirical lawlikeness could not have been established in the Principles of the Critique given the differences between transcendental, metaphysical and empirical lawlikeness, and the connection between the faculty of Reason and empirical lawlikeness. I then discuss the general conditions for empirical hypotheses according to Kant, which include the justification of the method by which an empirical hypothesis is obtained and the establishment of the (...) general and specific constructability of the empirical concept. -/- *In Chapter II, I discuss the nature of the general construction of concepts which is treated in the Schematism of the Critique, surveying the views of Pippin, Allison, Bennett and Butts in an effort both to make sense of a difficult part of the Critique and to demonstrate that the Schematism is indeed where Kant demonstrates how the construction of empirical concepts in general is possible. -/- *In Chapter III, I discuss Brittan’s and Butts’ views on the nature of the specific construction of empirical concepts, defending Butts’ interpretation as compatible with Buchdahl’s view that gaps exist between kinds of lawlikeness for Kant and, because of its connection with an interpretation of how metaphysical lawlikeness figures in the Metaphysical Foundations of Natural Science, insofar as it helps us to establish the possibility of empirical lawlikeness and natural science.

Paleobiologists often provide simple narratives to explain complex, contingent episodes. These narratives are sometimes ‘one-shot hypotheses’ which are treated as being mutually exclusive with other possible explanations of the target episode, and are thus extended to accommodate as much about the episode as possible. I argue that a provisional preference for such hypotheses provides two kinds of productive scaffolding. First, they generate ‘hypothetical difference-makers’: one-shot hypotheses highlight and isolate empirically tractable dependencies between variables. Second, investigations of hypothetical (...) difference-makers provision explanatory resources, the ‘raw materials’ for constructing more complex—and likely more adequate—explanations. Provisional preferences for simple, one-shot hypotheses in historical science, then, is defeasibly justified on indirect—strategic—grounds. My argument is made in reference to recent developments regarding the K–Pg extinction. (shrink)

Empirical agreement is often used as an important criterion when assessing the validity of scientific models. However, it is by no means a sufficient criterion as a model can be so adjusted as to fit available data even though it is based on hypotheses whose plausibility is known to be questionable. Our aim in this paper is to investigate into the uses of empirical agreement within the process of model validation.

The aim of this study is to evaluate the level of select ethical issues in Visegrad Four (V4) countries (Czech republic, Slovakia, Poland, and Hungary) and quantify the differences in the attitudes of entrepreneurs in the field of business ethics in these countries. Empirical research was conducted in June 2022 in the V4 countries. Data collection was carried out by the renowned external company MNFORCE using "Computer Assisted Web Interviewing" (CAWI Research Method), according to the questionnaire created by the (...) research team. The total number of respondents was 1,398, of which 347 were from the Czech Republic, 322 from Slovakia, 381 from Poland, and 348 from Hungary. Statistical hypotheses were verified using descriptive statistics, chi-square, and Z-scores at a α = 5% significance level. The preliminary results of this study can be evaluated as follows: The ethical level of entrepreneurs in V4 countries is high because the dominant group showed a positive attitude towards the defined issues in the field of business ethics. The attitudes of these entrepreneurs showed that they not only perceived the importance of business ethics, but also implemented and promoted these practices in managerial decision-making. Moreover, they feel good when they behave ethically, which is a significant motivating factor. In this study, it was found that Hungarian SMEs presented the highest level of business ethics. In contrast, the Czech Republic presented the lowest level of perception and enforcement of business ethics. (shrink)

Technical hitches mar van Gelder's proposed map of the conceptual landscape, particularly with respect to descriptive levels and the trio of instantiation, realisation, and implementation.

The author considers the empirical component of physical theories. He studies the origin and development of the theory of physical experiment, the structure and gnoseological hypotheses of the measuring process, as well as the relativity principle concerning the measuring equipment. Examples of modern physical theories are used in order to demonstrate the influence of experimental facts on the formation and development, verification and accepting of these theories in the structure of scientific systems. The role of accidental experimental facts (...) in this process is also the subject. (shrink)

This study provides an additional partial test of the Hunt-Vitell theory [1986, Journal of Macro-marketing, 8, 5-16; 1993, 'The General Theory of Marketing Ethics: A Retrospective and Revision', in N. C. Smith and J. A. Quelch (eds.), Ethics in Marketing (Irwin Inc., Homewood), pp. 775-784], within the consumer ethics context. Using structural equation modeling, the relationships among an individual's personal values (conceptualized by the typology of Schwartz [1992, 'Universals in the Content and Structure of Values: Theoretical Advances and Empirical (...) Tests in 20 Countries', in M. P. Zanna (ed.), Advances in Experimental Social Psychology (Vol. 25, Academic Press, Orlando), pp. 1--65] ethical ideology and ethical beliefs are investigated. The validity of the model is assessed in a two-step procedure. First, a measurement model of constructs is tested for key validity dimensions. Next, the hypothesized causal relationships are examined in several path models, comparing no mediation, partial and complete mediation of ethical ideology. The empirical results indicate that individual differences in value priorities (resultant conservation and resultant self-enhancement) directly and indirectly (through idealism) influence the judgment of ethically questionable consumer practices. These findings may significantly contribute to the theoretical understanding of ethical decision-making. (shrink)

Although it is often said that economics is too much like physics, to a physicist economics is not at all like physics. The difference is in the scientific methods of the two fields: theoretical economics uses a top down approach in which hypothesis and mathematical rigor come first and empirical confirmation comes second. Physics, in contrast, embraces the bottom up ‘experimental philosophy’ of Newton, in which ‘hypotheses are inferred from phenomena, and afterward rendered general by induction’. Progress would (...) accelerates if economics were to truly make empirical verification the ultimate arbiter of theories, which would force it to open up to alternative approaches. (shrink)

I consider the error-statistical account as both a theory of evidence and as a theory of inference. I seek to show how inferences regarding the truth of hypotheses can be upheld by avoiding a certain kind of alternative hypothesis problem. In addition to the testing of assumptions behind the experimental model, I discuss the role of judgments of implausibility. A benefit of my analysis is that it reveals a continuity in the application of error-statistical assessment to low-level empirical (...) hypotheses and highly general theoretical principles. This last point is illustrated with a brief sketch of the issues involved in the parametric framework analysis of tests of physical theories such as General Relativity and of fundamental physical principles such as the Einstein Equivalence Principle.

In this paper, I present two ampliative adaptive logics: LA and LAk. LA is an adaptive logic for abduction that enables one to generate explanatory hypotheses from a set of observational statements and a set of background assumptions. LAk is based on LA and has the peculiar property that it selects those explanatory hypotheses that are empirically most successful. The aim of LAk is to capture the notion of empirical progress as studied by Theo Kuipers.

The underdetermination of theory by evidence must be distinguished from holism. The latter is a doctrine about the testing of scientific hypotheses; the former is a thesis about empirically adequate logically incompatible global theories or "systems of the world". The distinction is crucial for an adequate assessment of the underdetermination thesis. The paper shows how some treatments of underdetermination are vitiated by failure to observe this distinction, and identifies some necessary conditions for the existence of multiple empirically equivalent global (...) theories. We consider how empiricists should respond to the possibility of such systems of the world. (shrink)

The results of econometric modeling are fragile in the sense that minor changes in estimation techniques or sample can lead to statistical models that support inconsistent causal hypotheses. The fragility of econometric results undermines making conclusive inferences from the empirical literature. I argue that the program of evidential pluralism, which originated in the context of medicine and encapsulates to the normative reading of the Russo-Williamson Thesis that causal claims need the support of both difference-making and mechanistic evidence, offers (...) a ground for resolving empirical disagreements. I analyze a recent econometric controversy regarding the tax elasticity of cigarette consumption and smoking intensity. Both studies apply plausible estimation techniques but report inconsistent results. I show that mechanistic evidence allows for discriminating econometric models representing genuine causal relations from accidental dependencies in data. Furthermore, I discuss the differences between biological and social mechanisms and mechanistic evidence across the disciplines. I show that economists mainly rely on mathematical models to represent possible mechanisms. Still, claiming the actuality of the represented mechanisms requires establishing that crucial assumptions of these models are descriptively adequate. I exemplify my approach to assessing the quality of mechanistic evidence in economics with an analysis of two models of rational addiction. (shrink)

Frank Jackson has argued that only if we have a priori knowledge of the extension-fixers for many of our terms can we vindicate the methodological practice of relying on intuitions to decide between philosophical theories. While there has been much discussion of Jackson’s claim that we have such knowledge, there has been comparatively little discussion of this most powerful argument for that claim. Here I defend an alternative explanation of our intuitions about possible cases, one that does not rely on (...) a priori extension-fixers. This alternative explanation provides a vindication of our reliance on intuitions, while blocking Jackson’s abductive argument for a priori semantic knowledge. In brief, I argue that we should regard our armchair intuitions as providing an important, a priori source of evidence for hypotheses about the contents of our implicit referential policies with regard to our terms. But all such hypotheses have a potential falsifier that is only discoverable empirically. In other words, gold-standard evidence for such hypotheses is always empirical. (shrink)

Empirical philosophers of science aim to base their philosophical theories on observations of scientific practice. But since there is far too much science to observe it all, how can we form and test hypotheses about science that are sufficiently rigorous and broad in scope, while avoiding the pitfalls of bias and subjectivity in our methods? Part of the answer, we claim, lies in the computational tools of the digital humanities, which allow us to analyze large volumes of scientific (...) literature. Here we advocate for the use of these methods by addressing a number of large-scale, justificatory concerns—specifically, about the epistemic value of journal articles as evidence for what happens elsewhere in science, and about the ability of DH tools to extract this evidence. Far from ignoring the gap between scientific literature and the rest of scientific practice, effective use of DH tools requires critical reflection about these relationships. (shrink)

Damasio's somatic marker hypothesis (SMH) is a prominent neuroscientific hypothesis about the mechanisms implementing decision-making. This paper argues that, since its inception, the SMH has not been clearly formulated. It is possible to identify at least two different hypotheses, which make different predictions: SMH-G, which claims that somatic states generally implement preferences and are needed to make a decision; and SMH-S, which specifically claims that somatic states assist decision-making by anticipating the long-term outcomes of available options. This paper also (...) argues that neither hypothesis is adequately supported empirically; the task originally proposed to test SMH is not a good test for SMH-S, and its results do not support SMH-G either. In addition, it is not clear how SMH-G could be empirically invalidated, given its general formulation. Suggestions are made that could help provide evidence for SMH-S, and make SMH-G more specific. 1 Introduction 2 Two Hypotheses: Somatic Markers as Embodied Preferences, and as a Source of Farsightedness 3 Lack of Evidence for Somatic Farsightedness 4 Does Making Decisions Require Somatic Markers, and can it be Shown in the Laboratory? 5 Conclusion CiteULike Connotea Del.icio.us What's this?

This article contains reflections on the further structural transformation of the public sphere, building on the author’s widely-discussed social-historical study, The Structural Transformation of the Public Sphere, which originally appeared in German in 1962 (English translation 1989). The first three sections contain preliminary theoretical reflections on the relationship between normative and empirical theory, the deliberative understanding of democracy, and the demanding preconditions of the stability of democratic societies under conditions of capitalism. The fourth section turns to the implications of (...) digitalisation for the account of the role of the media in the public sphere developed in the original work, specifically to how it is leading to the expansion and fragmentation of the public sphere and is turning all participants into potential authors. The following section presents empirical data from German studies which shows that the rapid expansion of digital media is leading to a marked diminution of the role of the classical print media. The article concludes with observations on the threats that these developments pose for the traditional role of the public sphere in discursive opinion and will formation in democracies. (shrink)

Against the backdrop of frequent food safety problems, the importance of establishing food traceability systems has become increasingly important and urgent to address the contradiction between consumer information on safe food choices and the proliferation of problematic foods. The purpose of this study is to empirically study the influencing factors of Chinese consumers on the food traceability system in the food safety field. In this study, multiple models—push factor, pull factor, mooring factor, and switching intention—were integrated into the push-pulling-mooring theory (...) to form a conceptual PPM comprehensive model framework to study the switching intentions of two-dimensional code traceability technology for dairy products of Chinese consumers. By collecting the questionnaire survey, 305 valid questionnaires were collected from the consumers of middle- and high-end dairy products in China, and the influencing factors of thrust, pull, and mooring force were identified. The results showed that 10 of the 11 hypotheses were positive, but the impact of perceived risk on user satisfaction was negative. The important value of this study is to conduct a comprehensive empirical analysis of the key factors influencing consumer choice of traceable safe food through an integrated multi-model framework to help identify ways to establish and improve consumer willingness to use QR code traceable system products, to increase consumer confidence in the use of traceable and safe food choices.

In recent years an increasing number of political philosophers have begun to ground their arguments in empirical evidence. I investigate this novel approach by way of example.

Then I raise four worries about the application of his methodology that give rise to corresponding general recommendations for how to do empirical political philosophy. Proponents of this (...) approach should take care to (1) check for inappropriately narrow (and broad) samples, (2) verify studies’ relevance for their empirical hypotheses, (3) adjust their confidence to the available empirical evidence, and (4) properly integrate their hypotheses into their philosophical theorizing.

Chomsky has constructed an empirical theory about syntactic universals of natural language by defining a class of 'possible languages' which includes all natural languages (inter alia) as members, and claiming that all natural languages fall .within a specified proper subset of that class. I extend Chomsky's work to produce an empirical theory about natural4anguage semantic universals by showing that the semantic description of a language will incorporate a logical calculus, by defining a relatively wide class of 'possible calculi', (...) and by specifying a proper subset of that class which, I hypothesize, includes the calculi needed for the semantic description of any natural language. I argue that the special status, with respect to natural languages, of this particular type of logical calculus is an empirical finding which does not follow from any independently-known principles, and I conclude that the question why the laws of human thought have the structure they do is a biological rather than a logical question.

Since its origin, bioethics has attracted the collaboration of few social scientists, and social scientific methods of gathering empirical data have remained unfamiliar to ethicists. Recently, however, the clouded relations between the empirical and normative perspectives on bioethics appear to be changing. Three reasons explain why there was no easy and consistent input of empirical evidence into bioethics. Firstly, interdisciplinary dialogue runs the risk of communication problems and divergent objectives. Secondly, the social sciences were absent partners since (...) the beginning of bioethics. Thirdly, the meta‐ethical distinction between ‘is’ and ‘ought’ created a ‘natural’ border between the disciplines. Now, bioethics tends to accommodate more empirical research. Three hypotheses explain this emergence. Firstly, dissatisfaction with a foundationalist interpretation of applied ethics created a stimulus to incorporate empirical research in bioethics. Secondly, clinical ethicists became engaged in empirical research due to their strong integration in the medical setting. Thirdly, the rise of the evidence‐based paradigm had an influence on the practice of bioethics. However, a problematic relationship cannot simply and easily evolve into a perfect interaction. A new and positive climate for empirical approaches has arisen, but the original difficulties have not disappeared. (shrink)

Philosophers and psychologists generally hold that, in light of the empirical data, a subject lacks infallible access to her own mental states. However, while subjects certainly are fallible in some ways, I show that the data fails to discredit that a subject has infallible access to her own occurrent thoughts and judgments. This is argued, first, by revisiting the empirical studies, and carefully scrutinizing what is shown exactly. Second, I argue that if the data were interpreted to rule (...) out all such infallibility, the relevant psychological studies would be self-effacing. For they adopt a methodology where a subject is simply presumed to know her own second-order thoughts and judgments--as if she were infallible about them. After all, what she expresses as her second-order judgment is trusted as accurate without independent evidence — even though such judgments often misrepresent the subject’s first-order states. The upshot is that such studies do not discredit all infallibility hypotheses regarding self-attributions of occurrent states. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Empirical Questions Deserve Empirical AnswersColin MartindaleWhat is wrong with the current state of humanistic literary studies? On the theoretical level, we find various types of postmodernism, none of which makes much sense. On the other hand, there are approaches such as Marxism, Feminism, and the New Historicism. One can at least understand the contentions of such theorists, but these contentions are generally quite implausible. If poetry were (...) an effective means of maintaining the status quo or of oppressing anyone, one wonders why this was never noticed by politicians or generals. Now that the fact has been “discovered,” one wonders why it is not put to use by the power elite. What has led literary theory to stray onto such strange grounds? I believe that the faulty methods used by many literary theorists offer us at least part of an answer.Humanistic critics have no reasonable way of deciding among alternative answers if theorists happen to ask a question that is answerable—i.e., if they propose an empirical investigation. Their only method is one of producing examples and trying to persuade the reader. 1 Can a scientific approach provide something better? Certainly it can. First, the scientist does not pose unanswerable questions. Second, science provides methods for resolving disputes, for answering questions that are answerable. These methods are the scientific apparatus of counting, measuring, experimenting, and so on. Humanistic inquiry is simply not as effective as scientific inquiry. If a question is meaningful, it is by definition an empirical question. Science is the only method to us available for answering such questions. Humanism has no decision-making methods, no objective methods of choosing amongst competing hypotheses. [End Page 347]To paraphrase Plato, literary critics hypothesize many fine things but know nothing of how to test them. Science already has the methods. We merely need to apply them. To give an example from my own research, Raymond and a number of other literary scholars tried to say that across the course of the nineteenth century, the content of French poetry became more primary process (Freud), dedifferentiated (Werner), associative (Wundt), or mythic (Cassirer) in its content. 2 Unless one can translate Raymond’s comments into these theoretical terms, it is difficult to understand what in the world he is talking about, let alone to test his contention. Because literary critics usually make up their psychology as they go along, it is difficult to understand what they say. Because they have only a proof-by-example method, it is difficult to believe what they say. If we do make the translation and develop a metric to measure the degree to which poetic content is primary process, we can test Raymond’s hypothesis and find out if it is correct. 3 We can not only find out if it is correct. We can fit curves to the data, compute rates of change, relate rates of change to other variables, and so on. One cannot fit curves to what Lotman aptly called “literary chit-chat.” 4 Without such an objective measure of primary process content, one would no doubt assert that twentieth-century poetry is even more mythic in its content, because the poets themselves have said so. 5 In fact, the metric confirms Plato’s warning that poets lie.Some literary theorists, of course, do things that are at least close to science. Numbers would be of great help to such theorists if only as mnemonic devices. Given that people cannot hold more than about seven things in mind at once, the task of sorting out and comparing hundreds of texts is very difficult unless some counting is done. 6 Humanists can count, but they seem not to realize the value of this ability. Lévi-Strauss and the structuralists were doing what might be called zero-degree science. 7 It is reasonable to segment texts and look for regularities. It is not reasonable to look for regularities before one has determined the reliability of the segmentations: that is, before one has determined whether people agree as to how to segment texts. To compute a reliability coefficient, one has to use numbers, and one has to know the formula. Humanists don’t... (shrink)

Some desiderata for scientific confirmation are formulated in the light of a tentative scientific world view. Bayesian confirmation theories generically satisfy most of these desiderata, but one of them, "the strategy of ascent," fits best in a tempered personalist version of Bayesianism. There are both empirical and rational components, dialectically combined, in tempered personalism. The question of explanation vs. prediction is treated in a Bayesian manner, and it is found that both operations are susceptible to characteristic systematic errors. If (...) these are eliminated, however, then explanation and prediction provide equally good evidential support for hypotheses. (shrink)

Early modern experimental philosophers often appear to commit to and utilise corpuscular and mechanical hypotheses. This is somewhat mysterious, for such hypotheses frequently appear to be simply assumed, which is odd for a research program which emphasises the careful experimental accumulation of facts. Isaac Newton was one such experimental philosopher, and his optical work is considered a clear example of the experimental method. Focusing on his optical investigations, Walsh identifies three roles for hypotheses. First, Newton introduces a (...) hypothesis to explicate his abstract theory. The purpose here is primarily to improve understanding or uptake of the theory. Second, he uses a hypothesis as a platform from which to generate some crucial experiments to decide between competing accounts. The purpose here is to suggest experiments in order to bring a dispute to empirical resolution. Third, he uses a hypothesis to suggest an underlying physical cause, which he then operationalises and represents abstractly in his formal theory. The second and third roles are related in that they are both cases of scaffolding: hypotheses provide a temporary platform from which further experimental work and/or theorising can be carried out. In short, the entities and processes included in Newton’s optical hypothesis are not simply assumed hypothetical posits. Rather, they play instrumental roles in Newton’s experimental philosophy.

One of the major problems (or sometimes pseudo-problems) that archaeologists and historians encounter in the study of ancient cultures is the need to differentiate and to identify the sources of the various concepts, techniques, institutions, forms, designs, motifs, etc., that, at any given moment of time, form the constituent elements of the culture or cultural product to which they have turned their attention; or—to pose the question in its proper framework—to analyse the process of cultural formation inherent in the subject (...) of their study. Such considerations have a special significance for archaeologists, whose essential concern is with the often incomplete assemblages of material remains left behind by the cultures and civilizations of the past, and whose central task is to enumerate and reconstitute the structures and processes that were operative in the societies in question. The study of acculturation—culture change, cultural diffusion, “stimulus diffusion,” culture contact, etc.—has been part of the theoretical and empirical concerns of anthropologists and sociologists since some decades ago, and the subject of an old and now almost abandoned debate. While the terminology of the social sciences concerned with living societies can also be found in archaeological and historical discussion, such concerns have had inadequate application in the fields of archaeological and historical practice. What has dominated and, to a great extent, continues to dominate historical studies is what we might call “the ‘theory’ of influence” and its corollary, “the migration hypothesis.” Thus, it would not be an exaggeration to say that one of the leading aspects of the study of a past society or culture is the concern with the “parent” culture(s) which influenced it, or the search for the location of its “migratory origins.” While this is especially true of studies relating to the societies of the Third World, it is not exclusively so—as we see, for instance, in the case of European prehistory. The immediate epistemological sources of such approaches are not difficult to identify, being principally located in 19th century diffusionism and, as we shall see shortly, in colonial ideology.

The study examines the research methodology of more than 200 empirical investigations of ethics in personal selling and sales management between 1980 and 2010. The review discusses the sources and authorship of the sales ethics research. To better understand the drivers of empirical sales ethics research, the foundations used in business, marketing, and sales ethics are compared. The use of hypotheses, operationalization, measurement, population and sampling decisions, research design, and statistical analysis techniques were examined as part of (...) theory development and testing. The review establishes a benchmark, assesses the status and direction of the sales ethics research methodology, and helps inform researchers who need to deal with increasing amounts of empirical research. The investigation identified changing sources of publication with the Journal of Business Ethics and the Journal of Personal Selling & Sales Management maintaining their position as the main conduit of high quality empirical sales ethics research. The results suggest that despite the use of theoretical models for empirical testing, a greater variety of moral frameworks and wider use of marketing exchange theory is needed. The review highlights many sound aspects about the empirical sales ethics research statistical methodology but also raises concerns about several areas. Ways in which these concerns might be addressed and recommendations for researchers are provided. (shrink)

This article explores some open questions related to the problem of verification of theories in the context of empirical sciences by contrasting three epistemological frameworks. Each of these epistemological frameworks is based on a corresponding central metaphor, namely: (a) Neo-empiricism and the gambling metaphor; (b) Popperian falsificationism and the scientific tribunal metaphor; (c) Cognitive constructivism and the object as eigen-solution metaphor. Each of one of these epistemological frameworks has also historically co-evolved with a certain statistical theory and method for (...) testing scientific hypotheses, respectively: (a) Decision theoretic Bayesian statistics and Bayes factors; (b) Frequentist statistics and p-values; (c) Constructive Bayesian statistics and e-values. This article examines with special care the Zero Probability Paradox (ZPP), related to the verification of sharp or precise hypotheses. Finally, this article makes some remarks on Lakatos’ view of mathematics as a quasi-empirical science. (shrink)
