Standard economic theory says that the rational approach to a decision is to weigh all alternatives on all relevant dimensions and then to select the one with the highest weight. Such a procedure would maximize subjective expected utility. But, because of constraints on time and available information, people and other animals often bypass this process by using “fast and frugal” heuristics to make decisions. Rationality is thus said to be “bounded” by time and information constraints. The articles in this book describe and organize common heuristics. They show that use of such heuristics is generally the best approach to many real world problems and therefore not irrational. Heuristics evolved, they say, not as deviations from rationality but as aids to rationality in cases where the standard model would have proved to be too slow or inefficient. Although the approach of almost all of the authors of these papers is that of cognitive psychology—a focus on internal cognitive mechanisms—their findings and even their theories may be interpreted in terms of reinforcement and punishment acting on behavioral patterns.  相似文献

We conducted focus groups to assess patient attitudes toward research on medical practices in the context of usual care. We found that patients focus on the implications of this research for their relationship with and trust in their physicians. Patients view research on medical practices as separate from usual care, demanding dissemination of information and in most cases, individual consent. Patients expect information about this research to come through their physician, whom they rely on to identify and filter associated risks. In general, patients support this research, but worry that participation in research involving randomization may undermine individualized care that acknowledges their unique medical histories. These findings suggest the need for public education on variation in practice among physicians and the need for a collaborative approach to the governance of research on medical practices that addresses core values of trust, transparency, and partnership.  相似文献

We introduce the Decision Making Tendency Inventory (DMTI), a new scale for measuring the decision-making tendencies to maximize, to satisfice, and to minimize. The scale has promising psychometric properties. Our findings show that the revealed tendencies are independent from each other and from the specific decision-making domain. Each factor is differently related to a set of indices of well-being and functioning, suggesting intriguing considerations regarding the distinctive characteristics of maximizing, satisficing, and minimizing. The DMTI extends previous research on maximizing and might contribute to explain the inconsistent results in the literature. Directions for future research are suggested.  相似文献

This final collection of Skinner's papers was intended for the professional, although other readers will find much of interest. The first five chapters are devoted to what Skinner called “theoretical issues” and include clear presentations of his positions on “feelings” and on the “self” as an apparent agent of volition. Skinner skillfully discusses thinking, the origins of cognitive-mediational theories, and a favorite topic: the similarity of processes occurring in the histories of species and of individuals. The next four chapters cover what he called “professional issues,” including the often-misunderstood philosophy known as radical behaviorism as well as the operant aspects of behavior therapy and attempts to influence educational practices. He seemed disappointed in the lack of acceptance of programmed learning methods and pessimistic about the possibility of improving education practices. This pessimism was evident in the final section, “personal issues,” in which he expressed doubt that the powerful and self-serving forces of government, business, and religion will ever permit the changes that could be wrought by the application of behavior analysis to the great problems of society. Two other chapters in the last section will be useful to historians who are curious about the influence of logical positivism on Skinner's thinking (apparently there was not much influence) and to sophisticated readers who are interested in Skinner's retrospective consideration of his work.  相似文献

In an attempt to explain the stability of hierarchy, we focus on the perspective of the powerless and how a subjective sense of dependence leads them to imbue the system and its authorities with legitimacy. In Study 1, we found in a nationally representative sample of U.S. employees that financial dependence on one's job was positively associated with the perceived legitimacy of one's supervisor. In Study 2, we observed that a general sense of powerlessness was positively correlated with the perceived legitimacy of the economic system. In Studies 3 and 4, priming experimental participants with feelings of powerlessness increased their justification of the social system, even when they were presented with system‐challenging explanations for race, class, and gender disparities. In Study 5, we demonstrated that the experience of powerlessness increased legitimation of governmental authorities (relative to baseline conditions). The processes we identify are likely to perpetuate inequality insofar as the powerless justify rather than strive to change the hierarchical structures that disadvantage them.  相似文献

This collection maintains a dialogue between the analytic and continental traditions, while aspiring to situate itself beyond the analytic-continental divide. It divides into four parts, (1) Methodologies, (2) Truth and Meaning, (3) Metaphysics and Ontology, and (4) Values, Personhood and Agency, though there is considerable overlap among the categories. History and temporality are recurrent themes, but there is a lot of metaphysics generally, with some philosophy of language, philosophy of social science, ethics, political philosophy and epistemology. Less prominent is a pragmatic, deflationary attitude, and at a number of points I argue for the virtues of such an approach.  相似文献
