Combining economic, social-psychological and sociological approaches to trust, this book provides a general theoretical framework to causally explain conditional and unconditional trust; it also presents an experimental test of the corresponding integrative model and its predictions. Broadly, it aims at advancing a cognitive turn in trust research by highlighting the importance of (1) an actor ́s context-dependent definition of the situation and (2) the flexible and dynamic degree of rationality involved. In essence, trust is as “multi-faceted” as there are cognitive routes that take us to the choice of a trusting act. Therefore, variable rationality has to be incorporated as an orthogonal dimension to the typological space of trust. The theory presents an analytically tractable model; the empirical test combines trust games, high- and low-incentive conditions, framing manipulations, and psychometric measurements, and is complemented by decision-time analyses.

Trusting Others, Trusting God is an investigation of the concepts of moral and religious trust. The question of why or how it is rational to trust anyone has been the typical focus of philosophers, with an underlying assumption that trust must be justified. In most cases, trust (even – or perhaps especially religious trust) is portrayed as irrational. Sheela Pawar argues that a grammatical investigation of the concept of trust can help rectify this mistreatment.

This book develops a concept of vulnerability in International Relations that allows for a profound rethinking of a core concept of international politics: means-ends rationality. It explores traditions that proffer a more complex and relational account of vulnerability.

Trust is central to our social lives. We know by trusting what others tell us. We act on that basis, and on the basis of trust in their promises and implicit commitments. So trust underpins both epistemic and practical cooperation and is key to philosophical debates on the conditions of its possibility. It is difficult to overstate the significance of these issues. On the practical side, discussions of cooperation address what makes society possible-of how it is that life is not a Hobbesian war of all against all. On the epistemic side, discussions of cooperation address what makes the pooling of knowledge possible-and so the edifice that is science. But trust is not merely central to our lives instrumentally; trusting relations are themselves of great value, and in trusting others, we realise distinctive forms of value. What are these forms of value, and how is trust central to our lives? These questions are explored and developed in this volume, which collects fifteen new essays on the philosophy of trust. They develop and extend existing philosophical discussion of trust and will provide a reference point for future work on trust.

This book provides an introduction, discussion, and formal-based modelling of trust theory and its applications in agent-based systems This book gives an accessible explanation of the importance of trust in human interaction and, in general, in autonomous cognitive agents including autonomous technologies. The authors explain the concepts of trust, and describe a principled, general theory of trust grounded on cognitive, cultural, institutional, technical, and normative solutions. This provides a strong base for the author’s discussion of role of trust in agent-based systems supporting human-computer interaction and distributed and virtual organizations or markets (multi-agent systems). Key Features: Provides an accessible introduction to trust, and its importance and applications in agent-based systems Proposes a principled, general theory of trust grounding on cognitive, cultural, institutional, technical, and normative solutions. Offers a clear, intuitive approach, and systematic integration of relevant issues Explains the dynamics of trust, and the relationship between trust and security Offers operational definitions and models directly applicable both in technical and experimental domains Includes a critical examination of trust models in economics, philosophy, psychology, sociology, and AI This book will be a valuable reference for researchers and advanced students focused on information and communication technologies (computer science, artificial intelligence, organizational sciences, and knowledge management etc.), as well as Web-site and robotics designers, and for scholars working on human, social, and cultural aspects of technology. Professionals of ecommerce systems and peer-to-peer systems will also find this text of interest.

A TIMES BOOK OF THE YEAR 2021 'Punchy, funny and invigorating ... Pinker is the high priest of rationalism' Sunday Times 'If you've ever considered taking drugs to make yourself smarter, read Rationality instead. It's cheaper, more entertaining, and more effective' Jonathan Haidt, author of The Righteous Mind In the twenty-first century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that discovered vaccines for Covid-19 in less than a year produce so much fake news, quack cures and conspiracy theorizing? In Rationality, Pinker rejects the cynical cliché that humans are simply an irrational species - cavemen out of time fatally cursed with biases, fallacies and illusions. After all, we discovered the laws of nature, lengthened and enriched our lives and set the benchmarks for rationality itself. Instead, he explains, we think in ways that suit the low-tech contexts in which we spend most of our lives, but fail to take advantage of the powerful tools of reasoning we have built up over millennia: logic, critical thinking, probability, causal inference, and decision-making under uncertainty. These tools are not a standard part of our educational curricula, and have never been presented clearly and entertainingly in a single book - until now. Rationality matters. It leads to better choices in our lives and in the public sphere, and is the ultimate driver of social justice and moral progress. Brimming with insight and humour, Rationality will enlighten, inspire and empower. 'A terrific book, much-needed for our time' Peter Singer

Trust is a core concept in International Relations (IR), representing a key ingredient in state relations. It was only relatively recently that IR scholars began to probe what trust really is, how it can be studied, and how it affects state relations. In the process three distinct ways of theorising trust in IR have emerged: trust as a rational choice calculation, as a social phenomenon or as a psychological dimension. Trust in International Relations explores trust through these different lenses using case studies to analyse the relative strengths and weaknesses of different approaches. The case studies cover relations between: United States and India ASEAN and Southeast Asian countries Finland and Sweden USA and Egypt The European Union and Russia Turkey’s relations with the West This book provides insights with real-world relevance in the fields of crisis and conflict management, and will be of great interest for students and scholars of IR, security studies and development studies who are looking to develop a more sophisticated understanding of how different theories of trust can be used in different situations.
