“Rationality” has played a central role in shaping and establishing the hegemony of contemporary mainstream economics. As the specific claims of robust neoclassicism fade into the history of economic thought, an orientation toward situating explanations of economic phenomena in relation to rationality has increasingly become the touchstone by which mainstream economists identify themselves and ...

Given that the assumption of perfect rationality is rarely met in the real world, we explore a graded notion of rationality in socioecological systems of networked actors. We parametrize an actors' rationality via their place in a social network and quantify system rationality via the average Jensen-Shannon divergence between the games Nash and logit quantal response equilibria. Previous work h...

This paper investigates learning in the Santa Fe (El Farol) bar problem (sfbp). It is argued that rationality together with belief-based learning (e.g., Bayesian updating) yields unstable behavior in this game. More specifically, two conditions normally sufficient for convergence to Nash equilibrium, namely rationality and predictivity, are shown to be incompatible. Low-rationality learning alg...

We show how standard learning rules can be interpreted as small departures from rationality in the context of an asset pricing model. We propose a distinction between ‘internal rationality’, as agents that maximize discounted expected utility under uncertainty given consistent beliefs about the future, and ‘external rationality’as agents that know perfectly the true stochastic process for funda...

In the first part of the paper (sec. 1-4), I argue that Elqayam and Evan's (2011) distinction between normative and instrumental conceptions of cognitive rationality corresponds to deontological vs. teleological accounts in meta-ethics. I suggest that Elqayam and Evans' distinction be replaced by the distinction between a-priori intuition-based vs. a-posteriori success-based accounts of cogniti...

Socio-ecological systems are increasingly modelled by games played on complex networks. While the concept of Nash equilibrium assumes perfect rationality, in reality players display heterogeneous bounded rationality. Here we present a topological model of bounded rationality in socio-ecological systems, using the rationality parameter of the Quantal Response Equilibrium. We argue that system ra...

the paper deals with kant's conception of moral judgment. i start by criticizing a dominant interpretation of kant's practical rationality in its assertion that choosing, i.e. exercising judgment consists in adopting a maxim; and adopting a maxim is equivalent to acting on a principle, giving oneself the moral law (korsgaard). according to this view, the logical inescapability of choo...

there are few  shiite poets or authors who have defended the holy prophet(pbuh& hp) and his household and have not been under various accusations. this paper examines the contradictory views of historians in introducing shiite   poets, among which de'bel kazaee (martyred 246 lunar) is selected. the paper tries to answer  the following questions: considering all these contradictions can one...
