Using randomly generated sequences of binary events we asked participants to make predictions about the next event. It turned out that while predicting uncertain events, people do not behave unsystematically. Our research identifies four types of relatively consistent strategies for predicting uncertain binary events: a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run majority events, hereafter called the long-run momentum strategy ; a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run (...) minority events, called the long-run contrarian strategy ; a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run majority events, called the short-run momentum strategy ; and a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run minority events, called the short-run contrarian strategy . When the character of events remains unknown, the most common strategy is the short-run momentum strategy. With the increase of a perceived randomness of the situation, people tend more often to use the short-run contrarian strategy. People differ in their general beliefs about the continuation or reversal of a trend in various natural and social processes. Trend believers, when facing sequences of binary events commonly perceived as random, tend to use momentum strategies, whereas those who believe in the trend's reversal tend to use contrarian strategies.

This paper provides a model of the transition from hegemonic trade to contemporary (or fair) trade. Hegemonic trade is an instance of the two player game called Bully (Poundstone 1992) and Called Bluff (Snyder and Diesing 1977); contemporary trade is an instance of Prisoner's Dilemma (Krugman and Obstfeld 1991). In this paper, I show that a nation under the thumb of a hegemon, called the conciliatory nation, can induce fair trade. Further, I show that to induce fair trade, the conciliatory (...) nation must not be timied. (shrink)

This paper presents a theory of conclusions based upon the suggestions of Tukey [21]. The logic offered here is based upon two rules of detachment that occur naturally in probabilistic inference, a traditional rule of acceptance, and a rule of rejection. The rules of detachment provide flexibility: the theory of conclusions can account for both statistical and deductive arguments. The rule of acceptance governs the acceptance of new conclusions, is a variant of the rule of high probability, and is a (...) limiting case of a decision-theoretic rule of acceptance. The rule of rejection governs the removal of previously accepted conclusions on the basis of new evidence. The resulting theory of conclusions is not a decision-theoretic logic but does, through the aforementioned limiting property, provide a line of demarcation between decision and conclusion (i.e., nondecision) logics of acceptance. The theory of conclusions therefore complements decision-theoretic inference. The theory of conclusions presented here satisfies Tukey's desiderata, specifically: (1) conclusions are statements which are accepted on the basis of unusually strong evidence; (2) conclusions are to remain accepted unless and until unusually strong evidence to the contrary arises; (3) conclusions are subject to future rejection, when and if the evidence against them becomes strong enough. Finally, the proferred theory of conclusions has a strong conservative bias, reflecting Tukey's aims. (shrink)

In hisStudy of War, Q. Wright considered a model for the probability of warP during a period ofn crises, and proposed the equationP=1– n, wherep is the probability of war escalating at each individual crisis. This probability measure was formally derived recently by Cioffi -Revilla, using the general theory of political reliability and an interpretation of the n-crises problem as a branching process. Two new, alternate solutions are presented here, one using D. Bernoulli''s St. Petersburg Paradox as an analogue, the (...) other based on the logic of conditional probabilities. Analysis shows that, while Wright''s solution is robust with regard to the general overall behavior ofp andn, some significant qualitative and quantitative differences emerge from the alternative solutions. In particular,P converges to 1 only in a special case and not generally. (shrink)

Bicchieri (The grammar of society: The nature and dynamics of norms, 2006, xi) presents a formal analysis of norms that answers the questions of "when, how, and to what degree" norms affect human behavior in the play of games. The purpose of this paper is to apply a variation of the Bicchieri norms analysis to generate a model of norms-based play of the traditional deterrence game (Zagare and Kilgour, Int Stud Q 37: 1-27, 1993; Morrow, Game theory for political scientists, (...) 1994), the paradigmatic model of conflict initiation in International Relations. The deterrence game is modeled here as a sequential decision problem. As such, our analysis is an adaptation of Bicchieri's game-theoretic formalization of norms to what we will call the norms account of the game. We find that the standard account of the traditional deterrence game is a special case of the norms account of the game. We also show that the adaptation of Bicchieri's analysis of social norms yields new and interesting claims regarding when, how, and to what degree norms operate as a constraint on risk-related behavior in the traditional deterrence game. Moreover, we discuss how the results of the model provide testable propositions of relevance to the role of norms in international interactions. (shrink)

Time's mysteries seem to resist comprehension and what remains, once the familiar metaphors are stripped away, can stretch even the most profound philosopher. In Of Time and Lamentation, Raymond Tallis rises to this challenge and explores the nature and meaning of time and how best to understand it. The culmination of some twenty years of thinking, writing and wondering about (and within) time, it is a bold, original, and thought-provoking work. With characteristic fearlessness, Tallis seeks to reclaim time from (...) the jaws of physics. For most of us, time is composed of mornings, afternoons, and evenings and expressed in hurry, hope, longing, waiting, enduring, planning, joyful expectation, and grief. Thinking about it is to meditate on our own mortality. Yet, physics has little or nothing to say about this time, the time as it is lived. The story told by caesium clocks, quantum theory, and Lorentz coordinates, Tallis argues, needs to be supplemented by one of moss on rocks, tears on faces, and the long narratives of our human journey. Our temporal lives deserve a richer attention than is afforded by the equations of mathematical physics.The first part of the book, "Killing Time" is a formidable critique of the spatialized and mathematized account of time arising from physical science. Part 2, "Human Time" examines tensed time, the reality of time as it is lived: what we mean by "now", how we make sense of past and future events, and the idea of eternity. (shrink)

Association dominated theorizing about the mind in the English-speaking world from the early eighteenth century through the mid-twentieth and remained an important concept into the twenty-first. This endurance across centuries and intellectual traditions means that it has manifested in many different ways in different views of mind. This article traces associationist themes as they developed over the years by presenting the views of central historical figures in each era, focusing specifically on their conception of the associative relation and how it (...) operates in the mind.

Malgré un titre qui peut paraître imposant et intimider, le lecteur trouvera dans ce livre le condensé, particulièrement clair et élégant, que Raymond Ruyer voulut donner de sa pensée au soir de sa vie, en un ultime effort de présentation et d'actualisation. L'ouvrage, entièrement achevé, était jusqu'à ce jour inédit, ce qui fait de sa publication un événement. La pensée de Ruyer a retenu l'attention de nombre des penseurs les plus importants de la seconde moitié du XXe siècle (comme (...) Merleau-Ponty, Canguilhem, Deleuze ou Lacan), qui n'hésitaient pas à la placer au plus haut. La publication du dernier manuscrit philosophique de Ruyer représente l'occasion de se familiariser avec sa pensée et de lui accorder enfin la place qu'elle mérite. L'objectif du philosophe de Nancy a consisté à construire un système métaphysique ajusté aux découvertes de la science contemporaine. S'il est bien question ici de "Dieu", ce n'est pas dans la perspective d'une révélation : le Dieu de Ruyer est un Dieu spéculatif, comme celui d'Aristote ou de Whitehead, et nous sommes loin des considérations sur "le savant et la foi". D'autre part, "l'embryogenèse du monde" n'est pas une rêverie incontrôlée sur quelque Oeuf primordial, mais une tentative argumentée de constituer un panpsychisme à la manière de Leibniz, selon ce que Ruyer appelle lui-même une "monadologie corrigée".

Between people who unabashedly support eating meat and those who adopt moral vegetarianism, lie a number of people who are uncomfortably carnivorous and vaguely wish they could be vegetarians. Opposing animal suffering in principle, they can ignore it in practice, relying on the visual disconnect between supermarket meat and slaughterhouse practices not to trigger their moral emotions. But what if we could have the best of both worlds in reality—eat meat and not harm animals? The nascent biotechnology of tissue culture, (...) originally researched for medical applications, holds out just such a promise. Meat could be grown in vitro without killing animals. In fact, this technology may not just be an intriguing option, but might be our moral obligation to develop. (shrink)

Professor Raymond Wacks breaks down the leading theories of justice and illustrates how present-day challenges, like terrorism and migration, affect our fundamental notions of fairness and democratic freedoms.

What is law? Does it have a purpose? What is its relationship with justice? Do we have a moral duty to obey the law? These sorts of questions lie at the heart of jurisprudence. Moreover, every substantive or 'black letter' branch of the law raises questions about its own meaning and function. The law of contract cannot be properly understood without an appreciation of the concepts of rights and duties. The law of tort is directly related to several economic theories (...) of compensation. The criminal law is inextricably linked to philosophies of punishment? Understanding Jurisprudence explores these problems and provides an engaging introduction to the central issues of legal theory. The book navigates the reader through legal philosophy's fundamental concepts, concerns, and controversies. An experienced teacher of jurisprudence and distinguished writer in the field, Professor Wacks adopts an approach that is easy to follow and understand without avoiding the complexities and subtleties of the subject. Students of law, politics, philosophy, and other social sciences will find this an ideal guide to the essential themes of contemporary jurisprudence. Online Resource Centre A free online resource accompanies the book and provides the following resources: Analysis of current controversies of a jurisprudential nature such as current legal and moral controversies and political debates An additional chapter providing guidance and advice on the study of jurisprudence An interactive glossary of key terms relating to legal theory Further reading, including links to full text journal articles Questions and answers Useful Web links to support learning.

In Seeing Ourselves, philosopher and neuroscientist Raymond Tallis goes in search of what kind of beings we are, and where we might find meaning in our lives. Showcasing a remarkably detailed engagement with a huge range of disciplines, Tallis shows the unique nature of human consciousness.

Qu'entend-on par enchantement et désenchantement du monde? Quelles seraient les voies à suivre pour susciter un réenchantement du monde qui sera le fait de l’humain lui-même? La raison et la rationalité sont-elles les causes des maux de nos errements ou des outils pour les contrer? Suffira-t-il d’avoir « foi en la raison » pour surmonter les défis que l’humanité s’est elle-même imposés par négligence et irresponsabilité.
