Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about (...) fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

Case-based instruction is a stable feature of ethics education, however, little is known about the attributes of the cases that make them effective. Emotions are an inherent part of ethical decision-making and one source of information actively stored in case-based knowledge, making them an attribute of cases that likely facilitates case-based learning. Emotions also make cases more realistic, an essential component for effective case-based instruction. The purpose of this study was to investigate the influence of emotional case content, and complementary (...) socio-relational case content, on case-based knowledge acquisition and transfer on future ethical decision-making tasks. Study findings suggest that emotional case content stimulates retention of cases and facilitates transfer of ethical decision-making principles demonstrated in cases. (shrink)

During the past decade scientists, public policy analysts, politicians, and laypeople, have become increasingly aware of the importance of ethical conduct in scientific research. In this timely book, David B. Resnik introduces the reader to the ethical dilemmas and questions that arise in scientific research. Some of the issues addressed in the book include ethical decision-making, the goals and methods of science, and misconduct in science. The Ethics of Science also discusses significant case studies such as human and animal cloning, (...) the Challenger accident and Tobacco research. This is essential reading for anyone who wishes to understand the importance of ethics in science. (shrink)

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We Live (...) By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

Thomas S. Kuhn's classic book is now available with a new index.

Overview of the main issues about value pluralism.

Moral psychology investigates human functioning in moral contexts, and asks how these results may impact debate in ethical theory. This work is necessarily interdisciplinary, drawing on both the empirical resources of the human sciences and the conceptual resources of philosophical ethics. The present article discusses several topics that illustrate this type of inquiry: thought experiments, responsibility, character, egoism v . altruism, and moral disagreement.

The thirty-five chapters in this book describe various judgmental heuristics and the biases they produce, not only in laboratory experiments but in important...

The renowned philosopher John Searle reveals the fundamental nature of social reality. What kinds of things are money, property, governments, nations, marriages, cocktail parties, and football games? Searle explains the key role played by language in the creation, constitution, and maintenance of social reality. We make statements about social facts that are completely objective, for example: Barack Obama is President of the United States, the piece of paper in my hand is a twenty-dollar bill, I got married in London, etc. (...) And yet these facts only exist because we think they exist. How is it possible that we can have factual objective knowledge of a reality that is created by subjective opinions? This is part of a much larger question: How can we give an account of ourselves, with our peculiar human traits DS mind, reason, freedom, society - in a world that we know independently consists of mindless, meaningless particles? How can we account for our social and mental existence in a realm of brute physical facts? In answering this question, Searle avoids postulating different realms of being, a mental and a physical, or worse yet, a mental, a physical, and a social. There is just one reality: Searle shows how the human reality fits into that one reality. Mind, language, and civilization are natural products of the basic facts of the physical world described by physics, chemistry and biology. Searle explains how language creates and maintains the elaborate structures of human social institutions. These institutions serve to create and distribute power relations that are pervasive and often invisible. These power relations motivate human actions in a way that provides the glue that holds human civilization together. Searle shows how this account illuminates human rationality, free will, political power, and human rights. Our social world is a world created and maintained by language. (shrink)

We all have beliefs, even strong convictions, about what is just and fair in our social arrangements. How should these beliefs and the theories of justice that incorporate them guide our thinking about practical matters of justice? This wide-ranging collection of essays by one of the foremost medical ethicists in the USA explores the claim that justification in ethics, whether of matters of theory or practice, involves achieving coherence between our moral and non-moral beliefs. Amongst the practical issues addressed in (...) the volume are the design of health-care institutions, the distribution of goods between the old and the young, and fairness in hiring and firing. In combining ethical theory and practical ethics this volume will prove especially valuable to philosophers concerned with ethics and applied ethics, political theorists, bioethicists, and others involved in the study of public policy.

This book offers a philosophy for error-prone humans trying to understand messy systems in the real world.

With respect to questions of fact, people use heuristics – mental short-cuts, or rules of thumb, that generally work well, but that also lead to systematic errors. People use moral heuristics too – moral short-cuts, or rules of thumb, that lead to mistaken and even absurd moral judgments. These judgments are highly relevant not only to morality, but to law and politics as well. Examples are given from a number of domains, including risk regulation, punishment, reproduction and sexuality, and the (...) act/omission distinction. In all of these contexts, rapid, intuitive judgments make a great deal of sense, but sometimes produce moral mistakes that are replicated in law and policy. One implication is that moral assessments ought not to be made by appealing to intuitions about exotic cases and problems; those intuitions are particularly unlikely to be reliable. Another implication is that some deeply held moral judgments are unsound if they are products of moral heuristics. The idea of error-prone heuristics is especially controversial in the moral domain, where agreement on the correct answer may be hard to elicit; but in many contexts, heuristics are at work and they do real damage. Moral framing effects, including those in the context of obligations to future generations, are also discussed. (shrink)

This volume brings together Nussbaum's published papers on the relationship between literature and philosophy, especially moral philosophy. The papers, many of them previously inaccessible to non-specialist readers, explore such fundamental issues as the relationship between style and content in the exploration of ethical issues; the nature of ethical attention and ethical knowledge and their relationship to written forms and styles; and the role of the emotions in deliberation and self-knowledge. Nussbaum investigates and defends a conception of ethical understanding which involves (...) emotional as well as intellectual activity, and which gives a certain type of priority to the perception of particular people and situations rather than to abstract rules. She argues that this ethical conception cannot be completely and appropriately stated without turning to forms of writing usually considered literary rather than philosophical. It is consequently necessary to broaden our conception of moral philosophy in order to include these forms. Featuring two new essays and revised versions of several previously published essays, this collection attempts to articulate the relationship, within such a broader ethical inquiry, between literary and more abstractly theoretical elements.

Despite the increasing recognition that heuristics may be involved in myriad scientific activities, much about how to use them prudently remains obscure. As typically defined, heuristics are efficient rules or procedures for converting complex problems into simpler ones. But this increased efficiency and problem-solving power comes at the cost of a systematic bias. As Wimsatt showed, biased modelling heuristics can conceal errors, leading to poor decisions or inaccurate models. This liability to produce errors presents a fundamental challenge to the philosophical (...) value of heuristic analyses. Heuristics may be powerful and efficient procedures, but their practical value for science and epistemology is significantly mitigated if we do not have a principled methodology for knowing how to use them wisely. In this essay, I extend Wimsatt’s analyses to argue that this challenge for a heuristic methodology can be met by appealing to second-order, or meta-, heuristics—that is, practical guidelines that prescribe the appropriate conditions for a first-order heuristic’s use. 1 Introduction2 Background3 Heuristics and Meta-heuristics4 A Hierarchical Model and Three Applications4.1 Decision making in emergency medicine4.2 Mathematical explanation in physics4.3 Resilience in ecological management5 Conclusion.

Research ethics, once a platform for declaring intent, discussing moral issues and providing advice and guidance to researchers, has developed over time into an extra-legal regulatory system, complete with steering documents (ethics guidelines), overseeing bodies (research ethics committees) and formal procedures (informed consent). The process of institutionalizing distrust is usually motivated by reference to past atrocities committed in the name of research and the need to secure the trustworthiness of the research system. This article examines some limitations of this approach. (...) First, past atrocities cannot provide the necessary justification unless institutionalized distrust is a necessary or efficient means to prevent future ones – and there are several reasons to doubt this. Second, the efficacy of ethics review in safeguarding morally acceptable research depends on the moral competence and integrity of individual researchers – the very qualities that institutionalized distrust calls into question. Third, ethics guidelines cannot, as is sometimes assumed, educate or guide researchers in moral behaviour unless they already possess considerable capacity for moral judgment. Fourth, institutionalized distrust is a potential threat to the moral competence and integrity of researchers by encouraging a blinkered view of ethical issues, inducing moral heteronomy through incentives, and alienating them to research ethics. We conclude that the moral problem posed by inappropriate short-term behaviour on behalf of researchers is dwarfed by the potential long-term consequences if their moral competence is allowed to deteriorate. Measures must therefore be taken to ensure that researchers are equipped to take their individual responsibility and are not obstructed from so doing. (shrink)

Competition among scientists for funding, positions and prestige, among other things, is often seen as a salutary driving force in U.S. science. Its effects on scientists, their work and their relationships are seldom considered. Focus-group discussions with 51 mid- and early-career scientists, on which this study is based, reveal a dark side of competition in science. According to these scientists, competition contributes to strategic game-playing in science, a decline in free and open sharing of information and methods, sabotage of others’ (...) ability to use one’s work, interference with peer-review processes, deformation of relationships, and careless or questionable research conduct. When competition is pervasive, such effects may jeopardize the progress, efficiency and integrity of science. (shrink)

Research in psychology indicates that situations powerfully impact human behavior. Often, it seems, features of situations drive our behavior even when we remain unaware of these features or their influence. One response to this research is pessimism about human agency: human agents have little conscious control over their own behavior, and little insight into why they do what they do. In this paper we review classic and more recent studies indicating “the power of the situation,” and argue for a more (...) optimistic response. In our view, though psychological research indicates situational influence, it also indicates that knowledge about the impact of situations on behavior can boost agents’ power to counteract harmful situational effects.

Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits (...) of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.

There is a growing interest in ethical competence-building within nursing and health care practising. This tendency is accompanied by a remarkable growth of ethical guidelines. Ethical demands have also been laid down in laws. Present-day practitioners and researchers in health care are thereby left in a virtual cross-fire of various legislations, codes, and recommendations, all intended to guide behaviour. The aim of this paper was to investigate the role of ethical guidelines in the process of ethical competence-building within health care (...) practice and medical research. A conceptual and critical philosophical analysis of some paragraphs of the Helsinki Declaration and of relevant literature was performed. Three major problems related to ethical guidelines were identified, namely, the interpretation problem (there is always a gap between the rule and the practice, which implies that ethical competence is needed for those who are to implement the guidelines); the multiplicity problem (the great number of codes, declarations, and laws might pull in different directions, which may confuse the health care providers who are to follow them); and the legalisation problem (ethics concerns may take on a legal form, where ethical reflection is replaced by a procedure of legal interpretations). Virtue ethics might be an alternative to a rule based approach. This position, however, can turn ethics into a tacit knowledge, leading to poorly reflected and inconsistent ethical decisions. Ethical competence must consist of both being (virtues) and doing (rules and principles), but also of knowing (critical reflection), and therefore a communicative based model is suggested. (shrink)

The empirical basis for this article is threeyears of experience with ethical rounds atUppsala University Hospital. Three standardapproaches of ethical reasoning are examined aspotential explanations of what actually occursduring the ethical rounds. For reasons given,these are not found to be satisfyingexplanations. An approach called ``imaginativeethics'', is suggested as a more satisfactoryaccount of this kind of ethical reasoning. Theparticipants in the ethical rounds seem to drawon a kind of moral competence based on personallife experience and professional competence andexperience. By listening to (...) other perspectivesand other experiences related to one particularpatient story, the participants imaginealternative horizons of moral experience andexplore a multitude of values related toclinical practice that might be at stake. Inhis systematic treatment of aesthetics in theCritique of Judgement, Kant made use ofan operation of thought that, if applied toethics, will enable us to be more sensitive tothe particulars of each moral situation. Basedon this reading of Kant, an account ofimaginative ethics is developed in order tobring the ethical praxis of doctors and nursesinto sharper relief. The Hebraic and theHellenic traditions of imagination are used inorder to illuminate some of the experiences ofethical rounds. In conclusion, it is arguedthat imaginative ethics and principle-basedethics should be seen as complementary in orderto endow a moral discourse with ethicalauthority. Kantian ethics will do the job if itis remembered that Kant suggested only amodest, negative role of principle-baseddeliberation. (shrink)
