The Evolution of Reputation-Based Cooperation


Book Description

Gossiping and its reputation effects are viewed as the most powerful mechanism to sustain cooperation without the intervention of formal authorities. Being virtually costless, gossiping is highly effective in monitoring and sanctioning norm violators. Rational individuals cooperate in order to avoid negative reputations. But this narrative is incomplete and often leads to wrong predictions. Goal Framing Theory, a cognitive-behavioral approach anchored in evolutionary research, provides a better explanatory framework. Three overarching goal frames (hedonic, gain, and normative) constantly compete for being in our cognitive foreground. This Element argues that for gossip to have reputation effects, a salient normative goal frame is required. But since the hedonic mindset usually trumps gain and normative concerns, most gossip will be driven by hedonic motives and therefore not have strong reputation effects. Propositions on cultural, structural, dispositional, situational, and technological gossip antecedents and consequences are developed and illustrated with evidence from the empirical record.




The Oxford Handbook of Gossip and Reputation


Book Description

Gossip and reputation are core processes in societies and have substantial consequences for individuals, groups, communities, organizations, and markets.. Academic studies have found that gossip and reputation have the power to enforce social norms, facilitate cooperation, and act as a means of social control. The key mechanism for the creation, maintenance, and destruction of reputations in everyday life is gossip - evaluative talk about absent third parties. Reputation and gossip are inseparably intertwined, but up until now have been mostly studied in isolation. The Oxford Handbook of Gossip and Reputation fills this intellectual gap, providing an integrated understanding of the foundations of gossip and reputation, as well as outlining a potential framework for future research. Volume editors Francesca Giardini and Rafael Wittek bring together a diverse group of researchers to analyze gossip and reputation from different disciplines, social domains, and levels of analysis. Being the first integrated and comprehensive collection of studies on both phenomena, each of the 25 chapters explores the current research on the antecedents, processes, and outcomes of the gossip-reputation link in contexts as diverse as online markets, non-industrial societies, organizations, social networks, or schools. International in scope, the volume is organized into seven sections devoted to the exploration of a different facet of gossip and reputation. Contributions from eminent experts on gossip and reputation not only help us better understand the complex interplay between two delicate social mechanisms, but also sketch the contours of a long term research agenda by pointing to new problems and newly emerging cross-disciplinary solutions.




The Evolution of Cooperation


Book Description

A famed political scientist's classic argument for a more cooperative world We assume that, in a world ruled by natural selection, selfishness pays. So why cooperate? In The Evolution of Cooperation, political scientist Robert Axelrod seeks to answer this question. In 1980, he organized the famed Computer Prisoners Dilemma Tournament, which sought to find the optimal strategy for survival in a particular game. Over and over, the simplest strategy, a cooperative program called Tit for Tat, shut out the competition. In other words, cooperation, not unfettered competition, turns out to be our best chance for survival. A vital book for leaders and decision makers, The Evolution of Cooperation reveals how cooperative principles help us think better about everything from military strategy, to political elections, to family dynamics.

Game Theory Evolving


Book Description

The study of strategic action (game theory) is moving from a formal science of rational behavior to an evolutionary tool kit for studying behavior in a broad array of social settings. In this problem-oriented introduction to the field, Herbert Gintis exposes students to the techniques and applications of game theory through a wealth of sophisticated and surprisingly fun-to-solve problems involving human (and even animal) behavior. Game Theory Evolving is innovative in several ways. First, it reflects game theory's expansion into such areas as cooperation in teams, networks, the evolution and diffusion of preferences, the connection between biology and economics, artificial life simulations, and experimental economics. Second, the book--recognizing that students learn by doing and that most game theory texts are weak on problems--is organized around problems, and introduces principles through practice. Finally, the quality of the problems is simply unsurpassed, and each chapter provides a study plan for instructors interested in teaching evolutionary game theory. Reflecting the growing consensus that in many important contexts outside of anonymous markets, human behavior is not well described by classical "rationality," Gintis shows students how to apply game theory to model how people behave in ways that reflect the special nature of human sociality and individuality. This book is perfect for upper undergraduate and graduate economics courses as well as a terrific introduction for ambitious do-it-yourselfers throughout the behavioral sciences.

In addition, the book addresses fundamental concepts and studies in the development of GNC, making it a valuable resource for both beginners and researchers wanting to further their understanding of guidance, navigation, and control.




The Calculus of Selfishness


Book Description

A pioneer in evolutionary game theory looks at selfishness and cooperation How does cooperation emerge among selfish individuals? When do people share resources, punish those they consider unfair, and engage in joint enterprises? These questions fascinate philosophers, biologists, and economists alike, for the "invisible hand" that should turn selfish efforts into public benefit is not always at work. The Calculus of Selfishness looks at social dilemmas where cooperative motivations are subverted and self-interest becomes self-defeating. Karl Sigmund, a pioneer in evolutionary game theory, uses simple and well-known game theory models to examine the foundations of collective action and the effects of reciprocity and reputation. Focusing on some of the best-known social and economic experiments, including games such as the Prisoner's Dilemma, Trust, Ultimatum, Snowdrift, and Public Good, Sigmund explores the conditions leading to cooperative strategies. His approach is based on evolutionary game dynamics, applied to deterministic and probabilistic models of economic interactions. Exploring basic strategic interactions among individuals guided by self-interest and caught in social traps, The Calculus of Selfishness analyzes to what extent one key facet of human nature—selfishness—can lead to cooperation.




Early Evolution of Human Memory


Book Description

This work examines the cognitive capacity of great apes in order to better understand early man and the importance of memory in the evolutionary process. It synthesizes research from comparative cognition, neuroscience, primatology as well as lithic archaeology, reviewing findings on the cognitive ability of great apes to recognize the physical properties of an object and then determine the most effective way in which to manipulate it as a tool to achieve a specific goal. The authors argue that apes (Hominoidea) lack the human cognitive ability of imagining how to blend reality, which requires drawing on memory in order to envisage alternative future situations, and thereby modifying behavior determined by procedural memory. This book reviews neuroscientific findings on short-term working memory, long-term procedural memory, prospective memory, and imaginative forward thinking in relation to manual behavior. Since the manipulation of objects by Hominoidea in the wild (particularly in order to obtain food) is regarded as underlying the evolution of behavior in early Hominids, contrasts are highlighted between the former and the latter, especially the cognitive implications of ancient stone-tool preparation.




The Evolution of Social Behaviour


Book Description

How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.
