Research notes of Mark Pettinelli about cognitive science, cognitive psychology.

Doxastic voluntarism is the thesis that our beliefs are subject to voluntary control. While there’s some controversy as to what “voluntary control” amounts to (see 1.2), it’s often understood as direct control: the ability to bring about a state of affairs “just like that,” without having to do anything else. Most of us have direct control over, for instance, bringing to mind an image of a pine tree. Can one, in like fashion, voluntarily bring it about that one believes a (...) specific proposition? Doxastic voluntarists hold that, at least in some circumstances—such as when the evidence is ambiguous—we can. Doxastic involuntarists, in contrast, maintain that we cannot. Some involuntarists hold that the concept of belief itself precludes the possibility of believing voluntarily. Others hold that the impossibility of voluntary belief is a contingent psychological fact. Historically, the issue of doxastic voluntarism has been connected to how many think about religious commitment: a prominent view of faith is that it is a voluntary decision to believe. Furthermore, the issue of voluntarism has also been viewed as having bearing on fundamental questions in epistemology. For example, are epistemic norms duties to believe in certain ways? Are there practical or moral reasons to believe? If the answer to either question is “yes,” it seems some measure of voluntary doxastic control is required. -/- In section 1, we expand on the definition of doxastic voluntarism, and survey various kinds of control (e.g. direct, indirect, long-range) and the doxastic attitudes we might control (e.g. outright belief, withholding, credences). In section 2, we discuss a number of historical views on doxastic voluntarism. In section 3, we survey motivations for rejecting doxastic voluntarism. There are two general strategies: arguments that appeal to psychological considerations, and conceptual arguments regarding the nature of belief. In section 4, we survey five approaches to defending voluntarism: those that appeal to epistemic permissivism, doxastic compatibilism, skepticism, one-off considerations, and non-standard views of belief. In section 5, we cover empirical work on doxastic voluntarism. The last two sections discuss two implications of voluntarism. In section 6, we discuss voluntarism’s implications for the ethics of belief, and in section 7, we discuss issues at the intersection of voluntarism and religious faith. (shrink)

One justification for preregistering research hypotheses, methods, and analyses is that it improves the transparent evaluation of the severity of hypothesis tests. In this article, I consider two cases in which preregistration does not improve this evaluation. First, I argue that, although preregistration can facilitate the transparent evaluation of severity in Mayo’s error statistical philosophy of science, it does not facilitate this evaluation in Popper’s theory-centric approach. To illustrate, I show that associated concerns about Type I error rate inflation are (...) only relevant in the error statistical approach and not in a theory-centric approach. Second, I argue that a preregistered test procedure that allows deviations in its implementation does not provide a more transparent evaluation of Mayoian severity than a non-preregistered procedure. In particular, I argue that sample-based validity-enhancing deviations cause an unknown inflation of the test procedure’s Type I (familywise) error rate and, consequently, an unknown reduction in its capability to license inferences severely. I conclude that preregistration does not improve the transparent evaluation of severity in Popper’s philosophy of science or when deviations are allowed. (shrink)

This is an overview of the main themes and theses of _Reasons First_ for a book symposium, and intended to be read alongside the other contributions to that symposium.

The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p-hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view. I argue that questionable and other research practices do not usually inflate relevant Type I error rates. I begin (...) by introducing the concept of Type I error rates and distinguishing between statistical errors and theoretical errors. I then illustrate my argument with respect to model misspecification, multiple testing, selective inference, forking paths, exploratory analyses, p-hacking, optional stopping, double dipping, and HARKing. In each case, I demonstrate that relevant Type I error rates are not usually inflated above their nominal level, and in the rare cases that they are, the inflation is easily identified and resolved. I conclude that the replication crisis may be explained, at least in part, by researchers’ misinterpretation of statistical errors and their underestimation of theoretical errors. (shrink)

Next SectionIn a recent article in this journal, John Skorupski alleges that the expressivist view developed in Being For fails on its own terms. However, in order to set up his criticism of my book, he helps himself to the very assumption that it is the main contribution of my book to show how to reject. It is hardly a problem for me that you can re-create the problem I showed how to solve by making the very assumption that I (...) showed led to the problem. This article illustrates what might have led to Skorupski's confusion. (shrink)

The semantic theory of expressivism has been applied within metaethics to evaluative words like ‘good’ and ‘wrong’, within epistemology to words like ‘knows’, and within the philosophy of language, to words like ‘true’, to epistemic modals like ‘might’, ‘must’, and ‘probably’, and to indicative conditionals. For each topic, expressivism promises the advantage of giving us the resources to say what sentences involving these words mean by telling us what it is to believe these things, rather than by telling us what (...) it would be for them to be true. This, in turn, absolves these theories of the burden of holding that there is any general answer to what it is for these sentences to be true. However, expressivism is famously subject to a deep and general problem about how to account for the meanings of complex sentences – a problem variously known as the ‘Frege-Geach’ or ‘embedding’ problem. In this paper I will be interested in whether there are reasons to think that the embedding problem looks less difficult for some of these applications for expressivism, than for others. In particular, in this paper I will be interested in the prospects for expressivism about what I will call epistemics – a class which I take to include epistemic modals like ‘might’ and ‘must’, sentential adverbs like ‘probably’, adjectives like ‘likely’ and ‘improbable’, and so-called ‘open’ indicative conditionals like ‘if the Fed doesn’t intervene, then the economy will enter a deflationary spiral’. There are several reasons to be particularly interested in expressivism about epistemics, relating both to the philosophical payoffs of such a view, and relating to the technical prospects for making it work. In other work I’ve touched on the especially interesting philosophical payoffs which make expressivism about epistemics interesting; in this paper I will be interested primarily in evaluating the possibility that there are better prospects for making expressivism about epistemics work than there are for making expressivism work about other topics. There are two main reasons why one might suspect that expressivism about epistemics will have better prospects than expressivism about many other topics, including in metaethics.. (shrink)

The reading abilities of Filipino students have been a challenge for educators and policymakers alike. Despite government efforts to improve literacy rates in the Philippines, recent studies have shown that many students need help with reading comprehension, vocabulary development, and critical thinking skills. This research note examines the current state of reading abilities among Filipino students and potential areas for improvement. The poor reading abilities can be attributed to several factors, including a lack of resources and socioeconomic factors. However, there (...) are identified potential areas for improvement, such as promoting early literacy programs, investing in teacher training, and developing reading materials that are culturally relevant and engaging for Filipino students. These findings have important implications for education policies and practices in the Philippines and for educators and researchers seeking to improve reading abilities among Filipino students.

Quietist Moral Realists accept that there are moral facts and properties, while aiming to avoid many of the explanatory burdens thought to fall on traditional moral realists. This chapter examines the forms that Quietist Moral Realism has taken and the challenges it has faced, in order to better assess its prospects. The best hope, this chapter argues, lies in a pragmatist approach that distinguishes the different functions of diverse areas of discourse. This paves the way for a form of Quietism (...) that does not simply remain quiet about the explanatory demands of metaethics, but rather is able to diagnose where they go wrong. By combining a neopragmatic analysis of the discourse with an easy approach to ontology, , we can develop a form of Quietist Moral Realism that is far stronger than critics of quietism have appreciated.

Burgess (1997), building on Quine (1953), convincingly argued that claims in quantified modal logic cannot be understood as synonymous with or logically equivalent to claims about the analyticity of certain sentences. According to modal normativism, metaphysically necessary claims instead express or convey our actual semantic rules. In this paper, I show how the normativist can use Sidelle’s (1992a, 1995) neglected work on rigidity to account for two important phenomena in quantified modal logic: the necessity of identity and the substitutivity of (...) identicals into modal contexts.

Each truth has a truthmaker: an entity in virtue of whose existence that truth is true. So say truthmaker maximalists. Arguments for maximalism are hard to find, whereas those against are legion. Most accept that maximalism comes at a significant cost, which many judge to be too high. The scales would seem to be balanced against maximalism. Yet, as I show here, maximalism can be derived from an acceptable premise which many will pre-theoretically accept.

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to 0.025 (...) when testing H1,1 and H1,2, find a significant result for H1,1 (p < 0.025) and not for H1,2 (p > .0.025), and so claim support for H1,1 and not for H1,2. However, these separate individual inferences do not require an alpha adjustment. Only a statistical inference about the union alternative hypothesis “H1,1 or H1,2” requires an alpha adjustment because it is based on “at least one” significant result among the two tests, and so it refers to the familywise error rate. Hence, an inconsistent correction occurs when a researcher corrects their alpha level during multiple testing but does not make an inference about a union alternative hypothesis. In the present article, I discuss this inconsistent correction problem, including its reduction in statistical power for tests of individual hypotheses and its potential causes vis-à-vis error rate confusions and the alpha adjustment ritual. I also provide three illustrations of inconsistent corrections from recent psychology studies. I conclude that inconsistent corrections represent a symptom of statisticism, and I call for a more nuanced inference-based approach to multiple testing corrections. (shrink)

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We (...) Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Truthmaker semantics is a recent development in formal and philosophical semantics, with similar motivation and scope to possible worlds semantics. The technical background is rather different, however, and results in a more fine-grained hyperintensional notion of content, allowing us to distinguish between classically equivalent propositions. After briefly introducing the main ideas, this entry will describe the technical apparatus of state spaces and the central notions of content and partial content. It will then outline applications of truthmaker semantics in language, logic, (...) and other areas of philosophy. (shrink)

We can readily identify goal-directed systems and distinguish them from non-goal-directed systems. A woodpecker hunting for grubs is the first, a pendulum returning to rest is the second. But what is it to be a goal-directed system? Perhaps the dominant answer to this question, inspired by systems theories such as cybernetics, is that goal-directed systems are distinguished by their tendency to seek, aim at, or maintain some more-or-less easily identifiable goal. Cybernetics and the like would hold that physical systems subject (...) only to physical laws can exhibit such behavior. If sound, this systems approach to teleology would unify a diverse range of goal-directed phenomena and neatly side-step many traditional bogey-men of teleology, such as anthropomorphism and future causation. Goal-directed phenomena would be a normal feature of the natural causal world that could be described in purely descriptive and quantitative terms, and receive ordinary causal explanations. Thus, the systems approach promises to provide a naturalistic-cum-descriptive account of teleology suitable for use in naturalistic accounts of other phenomena, including the intentionality of mental states and even self-consciousness.

The growth of individuals and society heavily relies on education. Certain hindrances may prompt some students to halt their academic pursuits temporarily. This is known as "Balik-aral." The exploration of the quality of life, lived experiences, and challenges of grade 12 Balik-aral students was undertaken by the authors to break their silence and help them by developing recommendations that could be presented to the school's key stakeholders. A phenomenological approach was used to understand the phenomenon in a study involving five (...) grade 12 balik-aral students from different strands currently enrolled in a public school in Cebu City, Philippines. A structured interview was used to collect data, and significant themes emerged during data analysis using Colaizzi's method. The study revealed several sub-themes, including age disparities and pressure to obtain the diploma while maintaining quality of life. Additionally, key informants emphasized the sense of community and an immersive learning environment in their lived experiences as balik-aral students. Finally, competing priorities and scarcity of resources emerged as significant challenges for those involved in the study. Consequently, the investigation has determined that balik-aral students must be treated equitably to foster their engagement with their peers and enhance their self-assurance, ultimately leading to academic success.

This chapter puts to rest for all of eternity the self-undermining charge against conciliationism.

Stephen Yablo has argued that ascriptions of belief and knowledge are sensitive to _subject matter_ and that theorising in such terms may help resolve philosophical questions about the semantics of such ascriptions. _Truthmaker semantics_ offers a way of theorising about subject matters. My main aim in this paper is to investigate what a semantics for knowledge or belief ascriptions might look like within truthmaker semantics. I then discuss what the resulting account might have to say about the problem of logical (...) omniscience, the nature of concepts, and rational belief. (shrink)

Some objects we value because they afford a felt connection with people, events, or places connected with their past. Visiting Canterbury cathedral, you encounter the place where, in 1170, Archbishop Thomas Becket was murdered by four knights of Henry II. Knowing that you are standing in the very place where Becket’s blood was spilled gives the past event a sense of tangible reality. One feels ‘in touch with’ the past; history seems to ‘come alive’. In this paper, I propose an (...) explanation for the phenomenology of such experiences in terms of an imaginative activity that represents what an object is historically connected with as part of the object in the present. One imagines of the site of Becket’s murder Becket being murdered. According to my account, objects that embody their histories are representations in Kendall Walton’s sense: they have the function of serving as props in games of make-believe. (shrink)

What exactly is a philosophical intuition? And what makes such an intuition reliable, when it is reliable? This paper provides a terminological framework that is able answer to the first question, and then puts the framework to work developing an answer to the second question. More specifically, the paper argues that we can distinguish between two different "evidential roles" which intuitions can occupy: under certain conditions they can provide information about the representational structure of an intuitor's concept, and under different (...) conditions, they can provide information about whether or not a property is instantiated. The paper describes two principles intended to capture the difference between the two sets of conditions---that is, the paper offers a principle that explains when an intuition will be a reliable source of evidence about the representation structure of an intuitor's concept, and another principle that explains when an intuition will be a reliable source of evidence about whether or not a property is instantiated. The paper concludes by briefly arguing that, insofar as philosophers are interested using intuitions to determine whether or not some philosophically interesting property is instantiated by some scenario (for instance, whether knowledge is instantiated in a Gettier-case), the reliability of the intuition in question does not depend on whether or not the intuition is widely shared.

Many hold that aesthetic appreciation is sensitive to the authenticity or genuineness of an object. In a recent body of work, Carolyn Korsmeyer has defended the claim that genuineness itself is an aesthetic property. Korsmeyer’s aim is to explain our aesthetic appreciation of objects that afford a sense of being ‘in touch with the past’. In this paper, I argue that genuineness cannot explain our appreciation of these objects. There is no aesthetic experience of the genuine.

Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

It is an honor to receive such careful and attentive criticism. In this response, I attempt to put the criticisms of the reasons latesters into the context of my argumentative aims in the book and to point toward how they might be answered.

The purpose of this paper is to conceptualize and explore what I shall call the Common Subject Problem for ethics. The problem is that there seems to be no good answer to what property everyone who makes moral claims could be talking and thinking about. The Common Subject Problem is not a new problem; on the contrary, I will argue that it is one of the central animating concerns in the history of both metaethics and normative theory. But despite its (...) importance, the Common Subject Problem is essentially invisible on many contemporary ways of carving up the problems of metaethics and normative ethical theory. My aim, therefore, is to make progress – in part by naming the problem, but also by beginning to sketch out the contours of what gives the problem its force, by distinguishing between different paths of response to the problem and assessing some of their chief merits, and finally, by distinguishing the Common Subject Problem from another problem with which it has come to be conflated. This nearby problem is the Moral Twin Earth Problem. Whereas the Common Subject Problem is a problem about what property ‘wrong’ could refer to, the Moral Twin Earth Problem is a problem about how ‘wrong’ could refer to it. The upshot of the paper, therefore, is to rescue one of the historically significant problems in normative ethics and metaethics – a problem that is essentially about normative semantics – from the illusion that has persisted over the last twenty years that it is really, somehow, a problem about metasemantics. Once we have reclaimed this problem, we can see that it could still be a problem even if there are no distinctively metasemantic problems in metaethics at all, that it is a problem faced by a wider variety of views, and that the space of possible solutions is much wider and more interesting for normative theory, moral psychology, and moral epistemology.

Generic generalisations like ‘Opioids are highly addictive’ are very useful in scientific communication, but they can often be interpreted in many different ways. Although this is not a problem when all interpretations provide the same answer to the question under discussion, a problem arises when a generic generalisation is used to answer a question other than that originally intended. In such cases, some interpretations of the generalisation might answer the question in a way that the original speaker would not endorse. (...) Rather than excising generic generalisations from scientific communication, I recommend that scientific communicators carefully consider the kinds of questions their words might be taken to answer and try to avoid phrasing that might be taken to provide unintended answers.

Allow me to rehearse a familiar scenario. We all know that which ends you have has something to do with what you ought to do. If Ronnie is keen on dancing but Bradley can’t stand it, then the fact that there will be dancing at the party tonight affects what Ronnie and Bradley ought to do in different ways. In short, (HI) you ought, if you have the end, to take the means. But now trouble looms: what if you have (...) dreadful, murderous ends? Ought you to take the means to them? Seemingly not. But fortunately, an assumption made by deontic logics1 comes to the rescue. Since ‘‘ought’’, according to this assumption, is a sentential operator, HI must really be ambiguous. It could be read either as (Narrow) You have the end ! O(you take the means) or as (Wide) O(you have the end ! you take the means). Now if Narrow is true, then you really ought to take the means to your murderous ends. But this doesn’t follow from Wide. All that follows from Wide is that you ought to either take the means to these ends or else give them up. Conclusions: (1) Since HI is on some reading true, but Narrow isn’t, Wide is true. (2) Wide accounts for the relationship between your ends and what you ought to do. This elegant scenario repeats itself in many other domains in which it seems like something can have a bearing on what some particular agent ought to do. Does what you know affect what you ought to do? Do your beliefs about what you ought to do affect what you ought to do? Do your promises affect what you ought to do? Do your beliefs affect what you ought to believe? On each of these counts, the intuitive answer is ‘‘yes’’. And so each of these questions leaves something for the moral philosopher or the epistemologist to investigate. On each count, it seems that what we all know, is that (Account) you ought, if p, to do A. But on each count, the Narrow-scope reading of the ‘‘ought’’ in this claim yields unintuitive consequences. So since Account is true, it must be true on the Wide-scope reading.. (shrink)

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like attitude, with (...) world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)

This is a rough draft of a critical notice of Sergio Tenenbaum’s book, Appearances of the Good, for Social Theory and Practice.

Scientists often adjust their significance threshold during null hypothesis significance testing in order to take into account multiple testing and multiple comparisons. This alpha adjustment has become particularly relevant in the context of the replication crisis in science. The present article considers the conditions in which this alpha adjustment is appropriate and the conditions in which it is inappropriate. A distinction is drawn between three types of multiple testing: disjunction testing, conjunction testing, and individual testing. It is argued that alpha (...) adjustment is only appropriate in the case of disjunction testing, in which at least one test result must be significant in order to reject the associated joint null hypothesis. Alpha adjustment is inappropriate in the case of conjunction testing, in which all relevant results must be significant in order to reject the joint null hypothesis. Alpha adjustment is also inappropriate in the case of individual testing, in which each individual result must be significant in order to reject each associated individual null hypothesis. The conditions under which each of these three types of multiple testing is warranted are examined. It is concluded that researchers should not automatically assume that alpha adjustment is necessary during multiple testing. Illustrations are provided in relation to joint studywise hypotheses and joint multiway ANOVAwise hypotheses. (shrink)

Is PDP Connectionism compatible with Cognitive Linguistics? It is unfortunate that this question has not received the attention it deserves, since at stake is the very possibility of a unified "West Coast Cognitive Science" approach to language. Part I of this paper argues that a systematic approach to the question of compatibility must involve an enumeration and analysis of the general principles used by each research program in their linguistic explanations. This approach is carried out in Parts II and III, (...) and the conclusion is that the explanatory principles of PDP Connectionism are fundamentally data-driven, whereas those of Cognitive Linguistics rely essentially on structure that the mind contributes to language use. Part IV presents several computational models of metaphor and analogy as case studies of the practical difficulties involved in reconciling these two frameworks. Finally, Part V examines the philosophical foundations of their respective explanatory strategies in order to get a clearer view of the theoretical obstacles to a unified account. (shrink)

The debate over the meanings of indexical expressions has relied heavily on the method of counterexamples. This paper challenges that method by showing that purported counterexamples can often be explained away by appeal to perspective shifts. For these counterexamples to establish anything about indexical reference, we must identify the conditions under which theorists can legitimately appeal to perspective shifts. Some tests for semantic content are considered and it is argued that none of them can tell us when appeal to perspective (...) shift is admissible. The paper then considers how we should proceed if we become convinced that there is no way to identify the content of indexical expressions, offering reasons in favour of a nihilist conception of character over an epistemicist or pluralist conception.

In Taking Back Philosophy, Bryan Van Norden argues that members of philosophy departments in the United States should diversify their curricula to include more than just Anglo European thought. I concur with Van Norden that such diversification is a good worth realizing. Nonetheless, more needs to be said to derive substantive normative conclusions from this evaluative presupposition. I argue for the feasibility of responsibly teaching a more diverse philosophy curriculum, especially for those philosophy instructors who teach the bulk of philosophy (...) in undergraduate classrooms.

According to the Book of Common Prayer, we have sinned against God “in thought, word, and deed.” In this paper I’ll explore one way of understanding what it might mean to sin against God in thought—the idea that we can at least potentially wrong God by what we believe. I will be interested in the philosophical tenability of this idea, and particularly in its potential consequences for the epistemology of religious belief and the problem of evil.

Grounding is a powerful metaphysical concept; yet there is widespread scepticism about the intelligibility of the notion. In this paper, I propose an account of an entity’s nature or essence, which I then use to provide grounding conditions for that entity. I claim that an understanding of an entity’s nature, together with an account of how logically complex entities are grounded, provides all we need to understand how that entity is grounded. This approach not only allows us to say what (...) grounds what, it also sheds light on the formal features of the grounding relation. It provides a principled argument for the orthodox view that grounding is irreflexive, asymmetrical, and transitive; but it allows that it may not be well-founded. The resulting approach gives us a powerful framework for understanding nature, grounding, and the relationship between them. (shrink)

I develop and defend a truthmaker semantics for the relevant logic R. The approach begins with a simple philosophical idea and develops it in various directions, so as to build a technically adequate relevant semantics. The central philosophical idea is that truths are true in virtue of specific states. Developing the idea formally results in a semantics on which truthmakers are relevant to what they make true. A very natural notion of conditionality is added, giving us relevant implication. I then (...) investigate ways to add conjunction, disjunction, and negation; and I discuss how to justify contraposition and excluded middle within a truthmaker semantics. (shrink)

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests. In this article, we challenge this proposition and argue that there (...) are several advantages of exploratory hypothesis tests that can make their results more compelling than those of confirmatory hypothesis tests. We also consider some potential disadvantages of exploratory hypothesis tests and conclude that their advantages can outweigh the disadvantages. We conclude that exploratory hypothesis tests avoid researcher commitment and researcher prophecy biases, reduce the probability of data fraud, are more appropriate in the context of unplanned deviations, facilitate inference to the best explanation, and allow peer reviewers to make additional contributions at the data analysis stage. In contrast, confirmatory hypothesis tests may lead to an inappropriate level of confidence in research conclusions, less appropriate analyses in the context of unplanned deviations, and greater bias and errors in theoretical inferences.

This chapter lays out a case that with the proper perspective on the place of epistemology within normative inquiry more generally, it is possible to appreciate what was on the right track about some of the early approaches to the analysis of knowledge, and to improve on the obvious failures which led them to be rejected. Drawing on more general principles about reasons, their weight, and their relationship to justification, it offers answers to problems about defeat and the conditional fallacy (...) that plagued early defeasibility analyses of knowledge and offers a sketch of a contemporary alternative that is motivated by the idea that knowledge requires the right kind of “match” between objective and subjective factors.
