ABSTRACTPossibly, the replication crisis constitutes the most important problem in psychology. It calls into question whether psychology is a science. Existing conceptualizations of replicability depend on effect sizes; the larger the population effect size, the greater the probability of replication. This is problematic and contributes to the replication crisis. A different conceptualization, not dependent on population effect sizes, is desirable. The proposed solution features the closeness of sample means to their corresponding population means, in both the original and replication experiments. (...) If the researcher has specified the sampling precision desired, it is possible to calculate the probability of replication, prior to data collection, and without dependence on the population effect size or expected population effect size. In addition, it is not necessary to know population means or standard deviations, nor sample means or standard deviations, to employ the proposed a priori way of thinking about... (shrink)

Psychologists take two propositions for granted. Specifically, empirical verification of predictions derived from a theory support that the theory is more likely to be true and support that additional predictions derived from the theory have an increased probability of being sustained if subjected to empirical testing. In contrast, I argue that both propositions depend strongly on whether auxiliary assumptions are taken into account. When auxiliary assumptions are not taken into account, the first proposition is valid but the second is not. (...) When auxiliary assumptions are taken into account, the first proposition is not valid, and the second proposition encounters additional problems. I use Venn diagrams and Bayesian principles to demonstrate these conclusions. (shrink)

Whether people possess free will has been a long-lasting philosophical debate. Recent attention in social psychology has been given to the behavioral consequences of believing in free will. Research has demonstrated that manipulating free will beliefs has implications for many social behaviors. For example, free will belief manipulations have been associated with cheating, aggressiveness, and prejudice. Despite this work, some of these findings have failed to replicate. Testing theoretical predictions, such as whether believing in free will influences behavior, depends on (...) theoretical, auxiliary, statistical, and inferential assumptions (TASI). In this paper we apply the TASI category of assumptions to the free will belief debate. In doing so we demonstrate why these assumptions should be considered when appraising the influence of free will belief manipulations on free will beliefs and behavior. To provide a nuanced view of free will beliefs, we believe researchers should pay careful attention to these critical assumptions. (shrink)

Both naïve and sophisticated falsification arguments depend upon using the logic of modus tollens to employ empirical defeats to conclude that the theory is not true or that t...

The notion of Socratic Note Taking is introduced to enhance students’ learning from assigned readings. SNT features students asking questions and answering their own questions while doing the readings. To test the effectiveness of SNT, half the students from two sections of a philosophy course were assigned SNT on alternating weeks. Quizzes each week alternated between the two classes as either high or low stakes in a counterbalanced format. The design was a 2 x 2 x 2 within-participants factorial. On (...) ten-point quizzes, SNT made an average difference of 1.22 points. Furthermore, the results indicate that SNT is particularly effective with weaker students, e.g., we found a nearly three-point increase on ten-point quizzes for the weakest students. (shrink)

Philosophers and scientists agree that an important characteristic of theories is their internal coherence. I propose that there is a particular type of internal coherence, termed “unit coherence,” that has received insufficient attention from psychologists. When psychologists theorize about the mechanisms that bring about human behavior, the units in which the variables are expressed need to be consistent throughout the theory; this is unit coherence. The theory of reasoned action is an example of a unit incoherent theory. I explain why (...) this is so and also show how the theory can be made to be unit coherent. I also include examples of unit coherent theories to demonstrate that they are possible to have in psychology. Although the concept of unit coherence is somewhat subtle, it has surprising and far-reaching consequences. (shrink)

Barbey & Sloman (B&S) present five models that account for performance in Bayesian inference tasks, and argue that the data disconfirm four of them but support one model. Contrary to B&S, I argue that the cited data fail to provide strong confirmation or disconfirmation for any of the models.

Consumer autonomy is a fundamental topic for marketing ethics scholars. Nonetheless, autonomy’s philosophical treatment may have compromised its conceptual clarity. After reviewing the relevant ethics literature on consumer autonomy, the benefits of formally defining consumer autonomy are illustrated, and a novel formalization is adapted from potential performance theory mathematics. The goal is to transfigure a hitherto amorphous topic via a mathematical formalization that defines true autonomy, actual autonomy, reliability of wills, and reliability of product choice. The crucial and surprising result: (...) an action that decreases true autonomy can increase actual autonomy if that action engenders a sufficient increase in one or both types of reliability. Relating the insights from the formalization to the long-standing debates in consumer autonomy suggests fruitful avenues for future research. (shrink)

Concerns about business ethics have led many business schools to integrate ethics into the curriculum, with mixed results (May, Luth, & Schwoerer 2014, Wang & Calvano 2015, Waples, Antes, Murphy, Connelly & Mumford 2009). This paper seeks to improve our understanding of business students’ ethics by looking into their identity, a cognitive lens by which students see themselves and interpret their environment (Triandis 1989) and that can be relatively malleable to priming and socializing processes (Vignoles, Schwartz, & Luyckx 2011, Ybarra (...) & Trafimow 1998). Results show that undergraduate students with higher individual and lower collective identities report lower intentions to behave ethically. Moreover, our results show that a business education has the power to influence students’ ethical intentions by altering their individual and collective identities. Our results suggest that business schools should consider the effects of their curriculum and pedagogies on the development of individual and collective identities to educate more ethical business students.

Oxford Philosophical Texts Series Editor: John Cottingham The Oxford Philosophical Texts series consists of authoritative teaching editions of canonical texts in the history of philosophy from the ancient world down to modern times. Each volume provides a clear, well laid out text together with a comprehensive introduction by a leading specialist, giving the student detailed critical guidance on the intellectual context of the work and the structure and philosophical importance of the main arguments. Endnotes are supplied which provide further commentary (...) on the arguments and explain unfamiliar references and terminology, and a full bibliography and index are also included. The series aims to build up a definitive corpus of key texts in the Western philosophical tradition, which will form a reliable and enduring resource for students and teachers alike. David Hume's aim in writing An Enquiry concerning Human Understanding was to introduce his philosophy to a European culture in which many educated people read original works of philosophy. He gives an elegant and accessible presentation of strikingly original and challenging views about the limited powers of human understanding, the attractions of scepticism, the compatibility of free will and determinism, and weaknesses in the foundations of religion. Hume's philosophy was highly controversial in the eighteenth century and remains so today. The text printed in this edition is that of the Clarendon critical edition of Hume's works. A substantial introduction by the editor explains the intellectual background to the work and surveys its main themes. The volume also includes detailed explanatory notes on the text, a glossary of terms, a full list of references, and a section of supplementary readings. (shrink)

David Lewis (1941-2001) was Class of 1943 University Professor of Philosophy at Princeton University. His contributions spanned philosophical logic, philosophy of language, philosophy of mind, philosophy of science, metaphysics, and epistemology. In On the Plurality of Worlds, he defended his challenging metaphysical position, "modal realism." He was also the author of the books Convention, Counterfactuals, Parts of Classes, and several volumes of collected papers.

In both radical and mainstream environmental discourses, anthropocentrism (human centredness) is inextricably linked to modern industrial society's drive to control and dominate nature and the generation of our current environmental crisis. Such environmental discourses frequently argue for a retreat from anthropocentrism and the establishment of a harmonious relationship with nature, often invoking the supposed ecological harmony of indigenous peoples and/or other small-scale societies. In particular, the beliefs and values of these societies vis-à-vis their natural environment are taken to be instrumental (...) in their low environmental impact. Here it is argued that, aside from the empirically problematic nature of such claims, the beliefs of small-scale societies have been seen through an ethnocentric discursive framework which bifurcates belief systems into anthropocentric and ecocentric. Taking a meta-theoretical approach informed by Strong Structuration Theory, it is argued that the beliefs of small-scale societies about their relationship with nature should be recognised as lying on a continuum of anthropocentrism and understood in the context of their attempts to establish ‘environmental ontological security’ in the face of natural uncertainty.

De l'Ethique à Nicomaque au Principe Responsabilité de Hans Jonas, les fins de l'homme - notamment la réalisation parfaite de soi, pour chaque être, l'humanité de l'homme, l'humanité raisonnable dans ses formes les plus achevées - s'instruisent universellement, selon l'espace public et politique des Etats, de ces catégories fondamentales de l'existence. La triade philosophie-démocratie-progrès débouche sur la thèse principale de Platon selon laquelle, l'Etat est injuste et il faut le réformer. Si Platon considère la vie terrestre comme une prison, sa (...) théorie de la participation, conduit au pluralisme des idées, au dialogue, à l'esprit de tolérance, à la paix perpétuelle, dit Kant, condition de la réalisation de la République et d'accomplissement de la démocratie dans un progrès allant inéluctablement à l'infini. Justice, liberté, dignité, égalité et nécessité d'un vouloir-vivre-ensemble se dégagent de cet ouvrage, mais avec le constat sévère d'une mimésis négro-africaine destructurante. Toute autocratie ne peut s'éterniser puisque la liberté est immanente à l'homme. Les textes présentés ici ont pour ambition de réinterroger le socle philosophique de l'éthique et de la politique, de tenter d'en dégager le sens, la finalité et d'en souligner l'actualité en ce début du XXIe siècle.

Various U.S. laws, such as the Clean Air Act and the Food Quality Protection Act, require additional protections for susceptible subpopulations who face greater environmental health risks. The main ethical rationale for providing these protections is to ensure that environmental health risks are distributed fairly. In this article, we (1) consider how several influential theories of justice deal with issues related to the distribution of environmental health risks; (2) show that these theories often fail to provide specific guidance concerning policy (...) choices; and (3) argue that an approach to public decision making known as accountability for reasonableness can complement theories of justice in establishing acceptable environmental health risks for the general population and susceptible subpopulations. Since accountability for reasonableness focuses on the fairness of the decision-making process, not the outcome, it does not guarantee that susceptible subpopulations will receive a maximum level of protection, regardless of costs or other morally relevant considerations.

This book is a defense of modal realism; the thesis that our world is but one of a plurality of worlds, and that the individuals that inhabit our world are only a few out of all the inhabitants of all the worlds. Lewis argues that the philosophical utility of modal realism is a good reason for believing that it is true.

Both individually and as a collection, these essays will promote understanding and provoke further debate amongst students and established scholars alike.

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.
