INFORMS PubsOnline. MIT Center for Collective Intelligence. Dewey, John [Internet Encyclopedia of Philosophy] John Dewey was a leading proponent of the American school of thought known as pragmatism, a view that rejected the dualistic epistemology and metaphysics of modern philosophy in favor of a naturalistic approach that viewed knowledge as arising from an active adaptation of the human organism to its environment.
On this view, inquiry should not be understood as consisting of a mind passively observing the world and drawing from this ideas that if true correspond to reality, but rather as a process which initiates with a check or obstacle to successful human action, proceeds to active manipulation of the environment to test hypotheses, and issues in a re-adaptation of organism to environment that allows once again for human action to proceed.
With this view as his starting point, Dewey developed a broad body of work encompassing virtually all of the main areas of philosophical concern in his day. Table of Contents 1. Life and Works 2. 3. Action-theory. Recma | Revue internationale de l'économie sociale. Revuedumauss.com.
Metamagical Themas: Sanity and Survival. Dilemmas for Superrational Thinkers, Leading Up to a Luring Lottery Post Scriptum Irrationality Is the Square Root of All Evil In my June column, I spelled out plainly, for all to see, the superrational argument that applies to the Platonia Dilemma, for rolling an N-sided die and entering only if it came up on the proper side. Here, a similar argument goes through. In the Platonia Dilemma, where more than one entry is fatal to all, the ideal die turned out to have N faces, where N is the number of [pg759] players - hence, with 10,000 players, a 10,000-sided die.
With 6,667 faces on the die, each superrational player’s chance of winning is not quite 1 in 10,000, but more like 1 in 13,000; this is because there is about a 22 percent chance that no one’s die will land right, so no one will send in any entry at all, and no one will win. [pg760] Curiously, many if not most of the people who submitted just one entry patted themselves on the back for being “cooperators”. Did I find this amusing? List of psychological research methods. A wide range of research methods are used in psychology. These methods vary by the sources of information that are drawn on, how that information is sampled, and the types of instruments that are used in data collection.
Methods also vary by whether they collect qualitative data, quantitative data or both. Qualitative psychological research is where the research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research is where the research findings result from mathematical modeling and statistical estimation or statistical inference. Since qualitative information can be handled as such statistically, the distinction relates to method, rather than the topic studied. There are three main types of psychological research: The following are common research designs and data collection methods: Research designs vary according to the period(s) of time over which data is collected: Stangor, Charles.

Social Contract Theory Social contract theory, nearly as old as philosophy itself, is the view that persons’ moral and/or political obligations are dependent upon a contract or agreement among them to form the society in which they live. Socrates uses something quite like a social contract argument to explain to Crito why he must remain in prison and accept the death penalty.
However, social contract theory is rightly associated with modern moral and political theory and is given its first full exposition and defense by Thomas Hobbes. After Hobbes, John Locke and Jean-Jacques Rousseau are the best known proponents of this enormously influential theory, which has been one of the most dominant theories within moral and political theory throughout the history of the modern West. In the twentieth century, moral and political theory regained philosophical momentum as a result of John Rawls’ Kantian version of social contract theory, and was followed by new analyses of the subject by David Gauthier and others. 1.
Sample Chapter for Camerer, C.F.: Behavioral Game Theory: Experiments in Strategic Interaction. This file is also available in Adobe Acrobat PDF format Introduction GAME THEORY IS ABOUT WHAT HAPPENS when people--or genes, or nations--interact. In all of these situations, a person (or firm) must anticipate what others will do and what others will infer from the person's own actions. A game is a mathematical x-ray of the crucial features of these situations. A game consists of the "strategies" each of several "players" have, with precise rules for the order in which players choose strategies, the information they have when they choose, and how they rate the desirability (or "utility") of resulting outcomes. An appendix to this chapter describes the basic mathematics of game theory and gives some references for further reading.
Game theory has a very clear paternity. In the past fifty years, game theory has gradually become a standard language in economics and is increasingly used in other social sciences (and in biology). It is important to distinguish games from game theory. Game Theory 101: The Prisoner's Dilemma. Théorie des jeux. La théorie des jeux est un domaine des mathématiques qui propose une description formelle d'interactions stratégiques entre agents (appelés « joueurs »)[1]. Les fondements mathématiques de la théorie moderne des jeux sont décrits autour des années 1920 par Ernst Zermelo dans l'article Über eine Anwendung der Mengenlehre auf die Theorie des Schachspiels[notes 1], et par Émile Borel dans l'article « La théorie du jeu et les équations intégrales à noyau symétrique ».
Ces idées sont ensuite développées par Oskar Morgenstern et John von Neumann en 1944 dans leur ouvrage Theory of Games and Economic Behavior[notes 2] qui est considéré comme le fondement de la théorie des jeux moderne. Il s'agissait de modéliser les jeux à somme nulle où la somme des gains entre les joueurs est toujours égale à zéro.
La théorie des jeux devient dès ce moment un outil théorique important de la microéconomie. Histoire[modifier | modifier le code] Interprétations[modifier | modifier le code] . , gain du joueur. Introduction to Game Theory. Game Theory might be better described as Strategy Theory, or Theory of Interactive Decision Making. A strategic situation involves two or more interacting players who make decisions while trying to anticipate the actions and reactions by others. Game theory studies the general principles that explain how people and organizations act in strategic situations. Game theory studies strategy mainly through the analysis of different "games".
A "game" in game theory is a fully explicit structure within which players (agents) act strategically to maximize personal Utility. Games provide a simplified world within which to study strategy (as opposed to the real world where complexities get in the way of developing general principles).

'Snowdrift' game tops 'Prisoner's Dilemma' in explaining cooperation. When it comes to explaining the evolution of human cooperation, researchers have traditionally looked to the iterated Prisoner’s Dilemma (IPD) game as the paradigm. However, the observed degree of cooperation among humans is generally higher than predicted by mathematical models using the IPD, leaving unanswered the question of why humans cooperate to the extent they do. A group of researchers from the University of Lausanne in Switzerland and the University of Edinburgh in the UK suggests that a different game, called the “iterated Snowdrift game” (ISD), may more realistically reflect social situations that humans face, compared with the IPD.
In experimental tests, the proportion of cooperative acts in the ISD game (48%) was significantly higher than those in the IPD (29%). The cause for this difference is due to the higher risks of being exploited in the IPD compared with the ISD, where the risk of being exploited by someone who doesn’t cooperate when you do is lower.
