The author examines the character of the changes taking place in contemporary Serbian society. He emphasizes at the same time that contemporary Serbian philosophy is facing these crucial questions as well, which without it cannot be even addressed, let alone solved. The key difference between modern West European and contemporary Serbian societies, seen from the perspective of philosophy, is demonstrated most clearly in the manner of constituting institutions and transforming the modern Serbian society. In the process of building modern institutions philosophy, not just in our country but throughout the Slavic East, has not had the role it played in Europe. Here lies the explanation why natural consciousness and an original ethos, though considerably modified, still remain unadapted and today represent a major obstacle to the establishment of the rule of European law. Without a change in the sense of justice and respect for the law it is impossible to accomplish the transformation of the society in which the law recognized by a democratic state could not be super ordinate to any reason. The crucial role of philosophy in this process is seen by the author not only in establishing modern European institutions and acceptance of the principle of European legislation, but above all in its influence on the transformation of the original ethos and establishment of new criteria on which the reflection, decision making and action of any individual would be based. .

We propose conviction narrative theory (CNT) to broaden decision-making theory in order to better understand and analyse how subjectively means–end rational actors cope in contexts in which the traditional assumptions in decision-making models fail to hold. Conviction narratives enable actors to draw on their beliefs, causal models, and rules of thumb to identify opportunities worth acting on, to simulate the future outcome of their actions, and to feel sufficiently convinced to act. The framework focuses on how narrative and emotion combine to allow actors to deliberate and to select actions that they think will produce the outcomes they desire. It specifies connections between particular emotions and deliberative thought, hypothesising that approach and avoidance emotions evoked during narrative simulation play a crucial role. Two mental states, Divided and Integrated, in which narratives can be formed or updated, are introduced and used to explain some familiar problems that traditional models cannot.

ABSTRACT: This paper investigates business unit (BU) controllers’ inclination to engage in the creation of budgetary slack. In particular, we explore whether controllers who are involved in BU decision making are more susceptible to social pressure to engage in slack creation than controllers who are not. We expect, and find, a crucial role of the controller’s personality. Results from an experiment among 136 management accountants suggest that the personality construct Machiavellianism interacts with involvement to explain controllers’ responses to social pressure to create budgetary slack. Controllers scoring high on Machiavellianism are more likely to give in to pressure by BU management to create budgetary slack when they have been involved in decision making. In contrast, controllers scoring low on Machiavellianism are less likely to give in to pressure to create slack when they have been involved in decision making.

AbstractLearning the transition structure of the environment – the probabilities of transitioning from one environmental state to another – is a key prerequisite for goal-directed planning and model-based decision making. To investigate the role of the orbitofrontal cortex (OFC) in goal-directed planning and decision making, we used fMRI to assess univariate and multivariate activity in the OFC while humans experienced state transitions that varied in degree of surprise. In convergence with recent evidence, we found that OFC activity was related to greater learning about transition structure, both across subjects and on a trial-by-trial basis. However, this relationship was inconsistent with a straightforward interpretation of OFC activity as representing a state prediction error that would facilitate learning of transitions via error-correcting mechanisms. The state prediction error hypothesis predicts that OFC activity at the time of observing an outcome should increase expectation of that observed outcome on subsequent trials. Instead, our results showed that OFC activity was associated with increased expectation of the more probable outcome; that is, with more optimal predictions. Our findings add to the evidence of OFC involvement in learning state-to-state transition structure, while providing new constraints for algorithmic hypotheses regarding how these transitions are learned.Significance StatementThe orbitofrontal cortex (OFC) has been implicated in model-based decision making—the kind of decisions that result from planning using an “environment model” of how current actions affect our future states. However, the widely suggested role of the OFC in representing expected values of future states is not sufficient to explain why the OFC would be critical for planning in particular. A new line of evidence implicates the OFC in learning about transition structure of the environment – a key component of the “environment model” used for planning. We investigate this function, adding to the growing literature on the role of the OFC in learning and decision making, while unveiling new questions about the algorithmic role of OFC in goal-directed planning.

New continuous and stochastic extensions of the Minority Game, devised as a fundamental model for a market of competitive agents, are introduced and studied in the context of statistical physics. The new formulation reproduces the key features of the original model, without the need for some of its special assumptions and, most importantly, it demonstrates the crucial role of stochastic decision-making. Furthermore, this formulation provides the exact but novel nonlinear equations for the dynamics of the system.

Abstract In several civil law systems of justice, the judiciary’s role traditionally gives rise to an institutional debate due to the absence of precedent as a source of formal law. The courts’ ability to operate thus depends, among other matters, upon public acceptance of their function. However, in the U.S. system, Justice Ginsburg, as a “judge’s judge,” properly sustained the role of the judiciary’s legitimacy by defining her considerations of “substitutes of consent”: deference to precedent, judicial restraint, collegiality, judicial interdependence, and procedural accountability. Among these factors, deference to precedent played a crucial role that emerged from Ginsburg’s “measured motion” of decision-making. Should her values framework thus have an impact on civil law systems of justice? To answer this question, we will examine two civil law procedure institutions, along with their jurisprudence, through the lens of Justice’s Ginsburg judicial philosophy. The results show how the traditional debate concerning these institutions must move from the institutions themselves to the judiciary’s role and its “motions”, following the path traced by Ginsburg’s judicial voice. Thus, her judicial philosophy now represents an international guideline to delineate those “substitutes of consent” and the courts’ decision-making approach to enhance the courts’ judicial legitimacy.

The alignment of habits with model-free reinforcement learning (MF RL) is a success story for computational models of decision making, and MF RL has been applied to explain phasic dopamine responses, working memory gating, drug addiction, moral intuitions, and more. Yet, the role of MF RL has recently been challenged by an alternate model---model-based selection of chained action sequences---that produces similar behavioral and neural patterns. Here, we present two experiments that dissociate MF RL from this prominent alternative, and present unconfounded empirical support for the role of MF RL in human decision making. Our results also demonstrate that people are simultaneously using model-based selection of action sequences, thus demonstrating two distinct mechanisms of habitual control in a common experimental paradigm. These findings clarify the nature of habits and help solidify MF RL's central position in models of human behavior.
