In this response, we clarify several misunderstandings of the understanding/acceptance principle and defend our specific operationalization of that principle. We reiterate the importance of addressing the problem of rational task construal and we elaborate the notion of computational limitations contained in our target article. Our concept of thinking dispositions as variable intentional-level styles of epistemic and behavioral regulation is explained, as is its relation to the rationality debate. Many of the suggestions of the commentators for elaborating two-process models are easily (...) integrated into our generic dual-process account. We further explicate how we view the relation between System 1 and System 2 and evolutionary and normative rationality. We clarify our attempt to fuse the contributions of the cognitive ecologists with the insights of the original heuristics and biases researchers. (shrink)

This paper reviews the largely psychological literature surrounding apparent failures of human rationality (sometimes referred to as 'the Rationality Wars') and locates it with respect to concepts and issues within more traditional epistemological inquiry. The goal is to bridge the gap between these two large and typically disconnected literatures – concerning rationality and the psychology of human reasoning, on the one hand, and epistemological theories of justified or rational belief, on the other – and to do so in such as (...) way as to expose interesting points of contact and convergence between them.

How ought we to go about forming and revising our beliefs, arguing and debating our reasons, and investigating our world? If those questions constitute normative epistemology, then I am interested here in normative metaepistemology: the investigation into how we ought to go about forming and revising our beliefs about how we ought to go about forming and revising our beliefs -- how we ought to argue about how we ought to argue. Such investigations have become urgent of late, for the (...) methodology of epistemology has reached something of a crisis. For analytic epistemology of the last half-century has relied overwhelmingly on intuitions,1 and a growing set of arguments and data has begun to call this reliance on intuition seriously into question (e.g., Weinberg, Nichols, and Stich 2001; Nichols, Stich, and Weinberg 2003; Cummins 1998). Although that method has not been entirely without defenders (BonJour 1998; Bealer 1996; Jackson 1998; Sosa forthcoming; Weatherson 2003), these defenses have not generally risen to the specific challenges leveled by the anti-intuitionist critics. In particular, the critics have attacked specific ways of deploying intuitions, and the defenders have overwhelmingly responded with in-principle defenses of the cogency of appealing to intuition. An analogy here would be someone’s responding to arguments alleging systematic.. (shrink)

In recent years evolutionary psychologists have developed and defended the Massive Modularity Hypothesis, which maintains that our cognitive architecture—including the part that subserves ‘central processing’ —is largely or perhaps even entirely composed of innate, domain-specific computational mechanisms or ‘modules’. In this paper I argue for two claims. First, I show that the two main arguments that evolutionary psychologists have offered for this general architectural thesis fail to provide us with any reason to prefer it to a competing picture of the (...) mind which I call the Library Model of Cognition. Second, I argue that this alternative model is compatible with the central theoretical and methodological commitments of evolutionary psychology. Thus I argue that, at present, the endorsement of the Massive Modularity Hypothesis by evolutionary psychologists is both unwarranted and unmotivated. (shrink)

Research from ethology and evolutionary biology indicates the following about the evolution of reasoning capacity. First, solving problems of social competition and cooperation have direct impact on survival rates and reproductive success. Second, the social structure that evolved from this pressure is the dominance hierarchy. Third, primates that live in large groups with complex dominance hierarchies also show greater neocortical development, and concomitantly greater cognitive capacity. These facts suggest that the necessity of reasoning effectively about dominance hierarchies left an indelible (...) mark on primate reasoning architectures, including that of humans. In order to survive in a dominance hierarchy, an individual must be capable of (a) making rank discriminations, (b) recognizing what is forbidden and what is permitted based one's rank, and (c) deciding whether to engage in or refriin from activities that will allow one to move up in rank. The first problem is closely tied to the capacity for transitive reasoning, while the second and third are intimately related to the capacity for deontic reasoning. I argue that the human capacity for these types of reasoning have evolutionary roots that reach deeper into our ancestral past than the emergence of the hominid line, and the operation of these evolutionarily primitive reasoning systems can be seen in the development of human reasoning and domain-specific effects in adult reasoning.

The 20 sup > th /sup > century has been a tumultuous time in psychology -- a century in which the discipline struggled with basic questions about its intellectual identity, but nonetheless managed to achieve spectacular growth and maturation. It’s not surprising, then, that psychology has attracted sustained philosophical attention and stimulated rich philosophical debate. Some of this debate was aimed at understanding, and sometimes criticizing, the assumptions, concepts and explanatory strategies prevailing in the psychology of the time. But much (...) philosophical work has also been devoted to exploring the implications of psychological findings and theories for broader philosophical questions like: Are humans really rational animals? How malleable is human nature? and Do we have any innate knowledge or innate ideas? One particularly noteworthy fact about philosophy of psychology in the 20 sup > th /sup > century is that, in the last quarter of the century, the distinction between psychology and the philosophy of psychology began to dissolve as philosophers played an increasingly active role in articulating and testing empirical theories about the mind and psychologists became increasingly interested in the philosophical underpinnings and implications of their work. Our survey is divided into five sections, each focusing on an important theme in 20 sup > th /sup > century psychology which has been the focus of philosophical attention and has benefited from philosophical scrutiny.

The mental model theory postulates that reasoners build models of the situations described in premises, and that these models normally represent only what is true. The theory has an unexpected consequence. It predicts the existence ofillusions in inferences. Certain inferences should have compelling but erroneous conclusions. Two experiments corroborated the occurrence of such illusions in inferences about what is possible from disjunctions of quantified assertions, such as, “at least some of the plastic beads are not red.” Experiment 1 showed that (...) participants erroneously inferred that impossible situations were possible, and that possible situations were impossible, but that they performed well with control problems based on the same premises. Experiment 2 corroborated these findings in inferences from assertions based on dyadic relations, such as, “all the boys played with the girls.”. (shrink)

In evolutionary biology, a trait is said to be optimal if it maximizes the fitness of the organism, that is, if the trait allows the organism to survive and reproduce better than any other competing trait would. In engineering, a design is said to be optimal if it complies with its functional requirements as well as possible. Cognitive science is both a biological and engineering discipline and hence it uses both notions of optimality. Unfortunately, the lack of a clear methodological (...) stance on this tissue has made it common for researchers to conflate these two kinds of optimality. In this paper, I argue that a strict distinction must kept in order to avoid inaccurate assumptions. (shrink)

Should we welcome social robots into interpersonal relationships? In this paper I show that an adequate answer to this question must take three factors into consideration: (1) the psychological vulnerability that characterizes ordinary interpersonal relationships, (2) the normative significance that humans attach to other people’s attitudes in such relationships, and (3) the tendency of humans to anthropomorphize and “mentalize” artificial agents, often beyond their actual capacities. I argue that we should welcome social robots into interpersonal relationships only if they are (...) endowed with a social capacity that is functionally similar to our own capacity for social norms. Drawing on an interdisciplinary body of research on norm psychology, I explain why this capacity is importantly different from pre-programmed, top-down conformity to rules, in that it involves an open-ended responsiveness to social corrective feedback, such as that which humans provide to each other in expressions of praise and blame.

In their recent and influential book Rethinking Innateness, Jeffrey Elman and his co‐authors argue that evidence from neurobiology provides us with grounds to reject representational nativism (RN). I argue that Elman et al.’s argument fails because it makes a series of unwarranted assumptions about RN and about the extent to which neurobiological data constrain claims about the innateness of mental rep‐resentations. Moreover, I briefly discuss how we ought to understand RN and argue that on two prima facie plausible approaches, far (...) from refuting nativism, the evidence from neurobiology may not even be relevant to the question of whether or not RN is true.

Samuels and Stich explore the debate over the extent to which ordinary human reasoning and decision making is rational. One prominent cluster of views, often associated with the heuristics and biases tradition in psychology, maintains that human reasoning is, in important respects, normatively problematic or irrational. Samuels and Stich start by sketching some key experimental findings from this tradition and describe a range of pessimistic claims about the rationality of ordinary people that these and related findings are sometimes taken to (...) support. Such pessimistic interpretations of the experimental findings have not gone unchallenged however: Samuels and Stich outline some of the research on reasoning that has been done by evolutionary psychologists and sketch a cluster of more optimistic theses about ordinary reasoning that such psychologists defend. Although Samuels and Stich think that the most dire pronouncements made by writers in the heuristics and biases tradition are unwarranted, they also maintain that the situation is rather more pessimistic than sometimes suggested by evolutionary psychologists. They conclude by defending this “middle way” and sketch a family of “dual processing” theories of reasoning which, they argue, offer some support for the moderate interpretation they advocate.

It is an old and venerable idea in philosophy that morality is built into us, and this nativist view has seen a resurgence of late. Indeed, the prevailing systematic account of how we acquire complex moral representations is a nativist view inspired by arguments in Chomskyan linguistics. In this article, I review the leading argument for moral nativism – the poverty of the moral stimulus. I defend a systematic empiricist alternative that draws on the resources of statistical learning. Such an (...) empiricist account, I argue, promises to explain much of the complexity of people’s moral and other normative attitudes. (shrink)

Cummins (this issue) puts the case for an innate module for deontic reasoning. We argue that this case is not persuasive. First, we claim that Cummins’evolutionary arguments are neutral regarding whether deontic reasoning is learned or innate. Second, we argue that task differences between deontic and indicative reasoning explain many of the phenomena that Cummins takes as evidence for a deontic module. Third, we argue against the suggestion that deontic reasoning is superior to indicative reasoning, either in adults or children. (...) Finally, we re‐evaluate Cummins’interpretation of differences in children's performance on deontic and indicative versions of Wason's selection task. (shrink)

La teoría de los contratos sociales es un enfoque cognitivo que apareció décadas atrás y que defiende que la mente humana se encuentra dotada con sistemas neurocognitivos evolutivos. Estos sistemas regulan diferentes situaciones sociales, por ejemplo, los intercambios y las negociaciones, y nos permiten detectar infractores de reglas o individuos que no cumplen acuerdos. En este trabajo, revisamos críticamente las tesis de este enfoque a partir de los argumentos lingüísticos de Moldovan sobre la perfección del condicional. Nuestra conclusión apunta a (...) que, si trasladamos los planteamientos de Moldovan a un plano más psicológico, podemos explicar los resultados de los experimentos que apoyan la teoría de los contratos sociales a partir del procesamiento de la información realizado por los participantes, sin necesidad de suponer sistema neurocognitivo evolutivo alguno.Social contracts theory is a cognitive approach that emerged decades ago and holds that human mind has evolved neurocognitive systems. These systems regulate different social situations, for example, exchanges and contracts, and allow detecting offenders and individuals that do not fulfill agreements. In this paper, I check critically the theses of this approach by means of the Moldovan’s linguistic arguments about conditional perfection. In this way, I conclude that, if we apply the Moldovan’s approach in a more psychological level, we can explain the outcomes of the experiments that support social contracts theory by means of the information processing made by the participants and we do not need to suppose that there are evolved neurocognitive systems.

The epistemic poverty objection is commonly levelled by externalists against deontological conceptions of epistemic justification. This is that an “oughts” based account of epistemic justification together with “ought” implies “can” must lead us to hold to be justified, epistemic agents who are objectively not truth-conducive cognizers. The epistemic poverty objection has led to a common response from deontologists, namely to embrace accounts of bounded rationality—subjective, practical or regulative accounts rather than objective, absolute or theoretical accounts. But the bounds deontological epistemologists (...) and their opponents entertain rarely include cultural limitations. This paper considers neo-Vygotskian arguments that we must consider such cultural limits in defending deontologism, and thus that any deontologically motivated perspectivism must be in part a cultural perspectivism. The dangers of strong relativism are flagged and an attempt is made to steer a.. (shrink)

Evolutionary debunking arguments purport to undercut the justification of our moral judgments by showing why a tendency to make moral judgments would evolve regardless of the truth of those judgments. Machery and Mallon (2010. Evolution of morality. In J.M. Doris and The Moral Psychology Research Group (Eds.), The Moral Psychology Handbook (pp. 3-46). Oxford: Oxford University Press) have recently tried to disarm these arguments by showing that moral cognition – in the sense that is relevant to debunking – is not (...) the product of natural selection. Specifically, they present a barrage of increasingly influential challenges against reciprocity-based approaches to moral nativism. In the present paper I defend the nativist account of moral cognition against these criticisms, thereby bolstering the skeptical conclusions of evolutionary debunking arguments. However, Machery and Mallon's critique does successfully highlight several vulnerabilities in Richard Joyce's approach to debunking, suggesting several ways in which it can be revised toward generating a more robust version of the argument.

A psychologically plausible analysis of the way we assign illocutionary forces to utterances is formulated using a 'contextualist' analysis of what is said. The account offered makes use of J. L. Austin's distinction between phatic acts (sentence meaning), locutionary acts (contextually determined what is said), illocutionary acts, and perolocutionary acts. In order to avoid the conflation between illocutionary and perlocutionary levels, assertive, directive and commissive illocutionary forces are defined in terms of inferential potential with respect to the common ground. Illocutionary (...) forces are conceived as automatic but optional components of the process of interpretation. (shrink)

Given the complexity of human social life, it is astonishing to observe how quickly children adapt to their social environment. To be accepted by the other members, it is crucial to understand and follow the rules and norms shared by the group. How and from whom do young children learn these social rules? In the experiments, based on the crucial role of affective social learning and dominance hierarchies in simple rule understanding, we showed 15-to-23-month-olds and 3-to-5-year-old children videos where the (...) agents’ body size and affective cues were manipulated. In the dominant rule-maker condition, when a smaller protagonist puts an object in one location, a bigger agent reacts with a positive reaction; on the contrary, when the smaller protagonist puts an object in another location, the bigger agent displays a negative reaction. In the subordinate rule-maker condition, the roles are shifted but the agents differ. Toddlers expect the protagonist to follow the rules (based on anticipatory looks), independent of the dominant status of the rule-making agent. Three-to-five-year-old pre-schoolers overall perform at the chance level but expect the protagonist to disobey a rule in the first trial, and obey the rule in the second trial if the rule-maker is dominant.

The “welcome return” to “substantive political philosophy” that Rawls'sA Theory of Justicewas said to herald has resulted in forty years of proposals seeking to show that philosophical reflection leads to the demonstrable truth of almost every and any conceivable view of the justice of property rights. Select any view—from the justice of unregulated capitalist markets to the most extreme forms of egalitarianism—and one will find that some philosophers have proclaimed that rational reflection uniquely leads to its justice. This is, I (...) believe, a sort of ideological thinking masquerading as philosophizing. In this paper, using some tools from game theory as well as experimental findings, I seek to sketch a non-ideological approach to the question of the justification of property rights. On this approach the aim of political philosophy is, first and foremost, to reflect on whether our social rules of property are within the “optimal eligible set” of rules acceptable to all. (shrink)

Abstract:When people reason on the basis of moral rules, do they suppose that in the absence of a prohibitory rule they are free to act, or do they suppose that morality always requires a justification establishing a permission to act? In this essay we present a series of learning experiments that indicate when learners tend to close their system on the basis of natural liberty and when on the principle of residual prohibition. Those who are taught prohibitory rules tend to (...) infer natural liberty while those taught permission rules tend to infer residual prohibition. In mixed cases, where learners are taught both types of rules, there is some tendency to suppose that natural liberty is the default. Both natural liberty and its denial can be learned; is there a reason to adopt one system of moral rules or the other? We argue that systems of social morality based on a principle of natural liberty have a striking advantage over their competitors: they are well adapted to effectively exploring the constant novel circumstances that arise in open, dynamic, societies.

From Mill to, most recently, Bryan Caplan, political and economic elites have been seen as the solution to the public’s ignorance and incompetence. In order to show that elites are actually more competent than the public, however, we would have to find out what type of knowledge is necessary to enact good public policy. The empirical evidence shows that economic experts have a slight advantage over the general public in knowledge of how to achieve policy goals. But, contrary to Caplan, (...) the evidence indicates that economists don’t possess significant predictive knowledge, and that general economic laws are of little help in predicting the magnitude of the effects of a specific policy in a multi‐variable, complex world. When we adopt a more complex understanding of the reasons behind policy choice, and consider rules and principles in addition to goal pursuit, the slight edge of economic experts evaporates.

These brief remarks highlight three aspects of Christian List and Philip Pettit's Group Agency: The Possibility, Design, and Status of Corporate Agents that illustrate its constructivist nature: its stress on the discursive dilemma as a primary challenge to group rationality and reasoning; its general though qualified support for premise-based decision-making as the preferred way to cope with the problems of judgment aggregation; and its account of rational agency and moral responsibility. The essay contrasts List and Pettit's constructivist analysis of group (...) rationality with an ecological approach, inspired by social theorists such as F A. Hayek, Vernon L.

Deontic reasoning is reasoning about permission and obligation: what one may do and what one must do, respectively. Conceivably, people could reason about deontic matters using a purely formal deontic calculus. I review evidence from a range of psychological experiments suggesting that this is not the case. Instead, I argue that deontic reasoning is supported by a collection of dissociable cognitive adaptations for solving adaptive problems that likely would have confronted ancestral humans.

Individual differences in performance on a variety of selection tasks were examined in three studies employing over 800 participants. Nondeontic tasks were solved disproportionately by individuals of higher cognitive ability. In contrast, responses on two deontic tasks that have shown robust performance facilitationthe Drinking-age Problem and the Sears Problem-were unrelated to cognitive ability. Performance on deontic and nondeontic tasks was consistently associated. Individuals in the correct/correct cell of the bivariate performance matrix were over-represented. That is, individuals giving the modal response (...) on a nondeontic task (P and Q) were significantly less likely to give the modal response on a deontic task (P and not-Q) than were individuals who made the non-modal P and not-Q selection on nondeontic problems. The implications of the results are discussed within the heuristic-analytic framework of Evans (1996; Evans & Over, 1996) and the optimal data selection model of Oaksford and Chater (1994). (shrink)

Aristotle thought we are by nature political animals, but the state-of-nature tradition sees political society not as natural but as an artifice. For this tradition, political society can usefully be conceived as emerging from a pre-political state of nature by the exercise of innate normative powers. Those powers, together with the rest of our native normative endowment, both make possible the construction of the state, and place sharp limits on the state's just powers and prerogatives. A state-of-nature theory has three (...) components. One is an account of the native normative endowment, or “NNE.” Two is an account of how the state is constructed using the tools included in the NNE. Three is an account of the state's resulting normative endowment, which includes a (purported) moral power to impose duties of obedience. State-of-nature theories disagree about the NNE. For Locke, it included a “natural executive right” to punish wrongdoing. Recent social scientific findings suggest a quite different NNE. Contrary to Locke, people do not behave in experimental settings as one would predict if they possessed a “natural executive right” to punish wrongdoing. Moral reproof is subject to standing norms. These norms limit the range of eligible reprovers. The social science can support two claims. One, is that the NNE is (as Aristotle held) already political. The other is that political authority can be re-conceived as a matter of standing—that is, as the state's unique moral permission coercively to enforce moral norms, rather than as a moral power to impose freestanding duties of obedience.

It is commonly supposed that evolutionary explanations of cognitive phenomena involve the assumption that the capacities to be explained are both innate and modular. This is understandable: independent selection of a trait requires that it be both heritable and largely decoupled from other ”nearby’ traits. Cognitive capacities realized as innate modules would certainly satisfy these contraints. A viable evolutionary cognitive psychology, however, requires neither extreme nativism nor modularity, though it is consistent with both. In this paper, we seek to show (...) that rather weak assumptions about innateness and modularity are consistent with evolutionary explanations of cognitive capacities. Evolutionary pressures can affect the degree to which the development of a capacity is canalized by biasing acquisition/learning in ways that favor development of concepts and capacities that proved adaptive to an organism’s ancestors.

Dominance hierarchies are ubiquitous in the societies of human and non-human animals. Evidence from comparative, developmental, and cognitive psychological investigations is presented that show how social dominance hierarchies shaped the evolution of the human mind, and hence, human social institutions. It is argued that the pressures that arise from living in hierarchical social groups laid a foundation of fundamental concepts and cognitive strategies that are crucial to surviving in social dominance hierarchies. These include recognizing and reasoning transitively about dominance relations, (...) fast-track learning of social norms (permissions, prohibitions, and obligations), detecting violations of social norms (cheating), monitoring reciprocal obligations, and reading the intentions of others.

This paper starts from an assumption defended in the author's previous work. This is that distinctivelyhuman flexible and creative theoretical thinking can be explained in terms of the interactions of a variety of modular systems, with the addition of just a few amodular components and dispositions. On the basis of that assumption it is argued that distinctively human practical reasoning, too, can be understood in modular terms. The upshot is that there is nothing in the human psyche that requires any (...) significant retreat from a thesis of massively modular mental organization. (shrink)

Prominent evolutionary psychologists have argued that our innate psychological endowment consists of numerous domainspecific cognitive resources, rather than a few domaingeneral ones. In the light of some conceptual clarification, we examine the central inprinciple arguments that evolutionary psychologists mount against domaingeneral cognition. We conclude (a) that the fundamental logic of Darwinism, as advanced within evolutionary psychology, does not entail that the innate mind consists exclusively, or even massively, of domainspecific features, and (b) that a mixed innate cognitive economy of domainspecific (...) and domaingeneral resources remains a genuine conceptual possibility. However, an examination of evolutionary psychology's 'grain problem' reveals that there is no way of establishing a principled and robust distinction between domainspecific and domaingeneral features. Nevertheless, we show that evolutionary psychologists can and do live with this grain problem without their whole enterprise being undermined. (shrink)

If you put chimpanzees from different communities together you can expect mayhem - they are not keen on treating each other nicely. There is closely related species of apes, however, whose members have countless encounters with unrelated specimen on a daily basis and yet almost all get through the day in one piece - that species is us, homo sapiens. But what makes us get along, most of the time? Morality as such is, perhaps surprisingly, not a mainstream research topic (...) in social psychology. Most textbooks in the field do not even mention the term morality at all (and focus on 'prosociality' instead). This relative lack of 'coverage' might have to do with the difficulty of operationalising 'morality' in a fitting way (more on this below). However, morality certainly is a social phenomenon and therefore the collection of Fargas, Jussim, and Van Lange is certainly a step in the right direction; it offers an extensive overview of the field and is suggestive of the vast potential of studying morality through the lens of social psychology.

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

Over the past few decades, reasoning and rationality have been the focus of enormous interdisciplinary attention, attracting interest from philosophers, psychologists, economists, statisticians and anthropologists, among others. The widespread interest in the topic reflects the central status of reasoning in human affairs. But it also suggests that there are many different though related projects and tasks which need to be addressed if we are to attain a comprehensive understanding of reasoning.

A basic question for virtue epistemology is whether it represents a ‘third force’ – a different source of normativity to that offered by internalism and externalism. It is argued that virtue epistemology does not offer us a distinct source of normativity. It is also argued that virtue theories offer us nothing that can unify the internalist and externalist sub-components of their preferred state of ‘virtue’. Claims that phronesis can unify a virtues-based axiology are specifically opposed.

One of the distinctive features of Gerald Gaus’s public justification theory is his extensive use of the empirical data from the social sciences to support his normative claims. One such claim which stands out for its importance, within the context of Gaus’s theory, is the evolution of strong reciprocity: over time, members of large societies develop a tendency to follow social rules and punish defectors. This claim, in turn, is supported by several studies in experimental economics involving mixed motive games, (...) which show how subjects are inclined to punish, even at a net cost for themselves, any perceived violation of social norms such as fairness. While critics of Gaus’s theory focused mainly on whether the use of empirical evidence in a normative theory is prima facie admissible, in this paper I address two different issues. The first concerns the accuracy of the empirical evidence used by Gaus’s theory, and whether the conclusions advanced by the social scientists on the grounds of this evidence are actually sound. The second issue, on the other hand, concerns the consistency between the empirical assumptions underlying these experiments and the claims of Gaus’s theory. I argue that both concerns are warranted. On the one hand, there is empirical evidence that the rule-following behavior observed in experiments involving mixed motive games is context dependent: the tendency of subjects to follow rules and punish defectors is strongly correlated to the epistemic constraints, such as anonymity, commonly imposed during the experiments. On the other hand, these constraints hardly reflect the circumstances of life in modern societies, which is the context assumed by Gaus’s justificatory theory. I conclude that Gaus’s account of rule-following punishers is not altogether invalidated, but the empirical evidence from experimental economics is insufficient to support it. (shrink)
