Rationality is a fundamental concept in economics. Most researchers will accept that human beings are not fully rational. Herbert Simon suggested that we are “bounded rational”. However, it is very difficult to quantify “bounded rationality”, and therefore it is difficult to pinpoint its impact to all those economic theories that depend on the assumption of full rationality. Ariel Rubinstein pr...

Most IS research takes for granted the assumption that IS practice and associated organizational change can be effectively understood as a process of technical reasoning and acting governed by a mix of concerns about software construction, administrative control and economic gain. Its mission has been to empower managers, IS engineers, and ICT users with knowledge and techniques for effective d...

in recent decades, rationality has become one of the important and controversial issues in the intellectual circles. there are many philosophers who have put (and still put) under question the status of reason and human rationality. among those who believe in human reason is popper. to show reason's ability, he rejects positivism and justifying approaches totally; and, designing falsificat...

The pace of organisational change within the National Health Service over the last two decades has been bewildering. Yet for all that, the rituals and routines of day-today general practice have seemed to endure without significant alteration. By contrast, the impact of the Quality and Outcomes Framework (QOF) has, arguably, exceeded that of any other policy development since the Family Doctors...

D and normative modeling of decision making under risk and uncertainty have grown apart over the past decade. Psychological models attempt to accommodate the numerous violations of rationality axioms, including independence and transitivity. Meanwhile, normatively oriented decision analysts continue to insist on the applied usefulness of the subjective expected utility (SEU) model. As this gap ...

The introduction of a small amount of bounded rationality into a model sometimes has little effect, and sometimes has a dramatic impact on predicted behavior. We call a model robust to bounded rationality if small deviations from rationality result only in small changes in the equilibrium set. We also say that a model is structurally stable if the equilibrium set (given fully rational agents) v...

According to one view about the rationality of belief, such rationality is ultimately nothing other than the rationality that one exhibits in taking the means to one’s ends. On this view, epistemic rationality is really a species or special case of instrumental rationality. In particular, epistemic rationality is instrumental rationality in the service of one’s distinctively cognitive or episte...

My aim in this paper is to explore the relationship between epistemic rationality and instrumental rationality. By epistemic rationality, I mean, roughly, the kind of rationality which one displays when one believes propositions that are strongly supported by one's evidence and refrains from believing propositions that are improbable given one's evidence. Prominent epistemologists frequently em...

Recent research in group cognition points towards the existence of collective cognitive competencies that transcend individual group members' cognitive competencies. Since rationality is a key cognitive competence for group decision making, and group cognition emerges from the coordination of individual cognition during social interactions, this study tests the extent to which collaborative and...
