There is a long-standing debate in the philosophy of mind and philosophy of science regarding how best to interpret the relationship between neuroscience and psychology. It has traditionally been argued that either the two domains will evolve and change over time until they converge on a single unified account of human behaviour, or else that they will continue to work in isolation given that they identify properties and states that exist autonomously from one another (due to the multiple-realizability of psychological (...) states). In this paper, I argue that progress in psychology and neuroscience is contingent on the fact that both of these positions are false. Contra the convergence position, I argue that the theories of psychology and the theories of neuroscience are scientifically valuable as representational tools precisely because they cannot be integrated into a single account. However, contra the autonomy position, I propose that the theories of psychology and neuroscience are deeply dependent on one another for further refinement and improvement. In this respect, there is an irreconcilable codependence between psychology and neuroscience that is necessary for both domains to improve and progress. The two domains are forever linked while simultaneously being unable to integrate. (shrink)

In robustness analysis, hypotheses are supported to the extent that a result proves robust, and a result is robust to the extent that we detect it in diverse ways. But what precise sense of diversity is at work here? In this paper, I show that the formal explications of evidential diversity most often appealed to in work on robustness – which all draw in one way or another on probabilistic independence – fail to shed light on the notion of diversity (...) relevant to robustness analysis. I close by briefly outlining a promising alternative approach inspired by Horwich’s (1982) eliminative account of evidential diversity. (shrink)

In an effort to carve a distinct place for social facts without lapsing into a holistic ontology, John Greenwood has sought to define social phenomena solely in terms of the attitudes held by the actor in question. I argue that his proposal allows for the possibility of a “lone collectivity” that is unpalatable in its own right and incompatible with the claim that sociology is autonomous from psychology. As such, I conclude that the relevant beliefs need to be held by (...) more than one person. (shrink)

Rational choice theory enjoys unprecedented popularity and influence in the behavioral and social sciences, but it generates intractable problems when applied to socially interactive decisions. In individual decisions, instrumental rationality is defined in terms of expected utility maximization. This becomes problematic in interactive decisions, when individuals have only partial control over the outcomes, because expected utility maximization is undefined in the absence of assumptions about how the other participants will behave. Game theory therefore incorporates not only rationality but also common (...) knowledge assumptions, enabling players to anticipate their co-players' strategies. Under these assumptions, disparate anomalies emerge. Instrumental rationality, conventionally interpreted, fails to explain intuitively obvious features of human interaction, yields predictions starkly at variance with experimental findings, and breaks down completely in certain cases. In particular, focal point selection in pure coordination games is inexplicable, though it is easily achieved in practice; the intuitively compelling payoff-dominance principle lacks rational justification; rationality in social dilemmas is self-defeating; a key solution concept for cooperative coalition games is frequently inapplicable; and rational choice in certain sequential games generates contradictions. In experiments, human players behave more cooperatively and receive higher payoffs than strict rationality would permit. Orthodox conceptions of rationality are evidently internally deficient and inadequate for explaining human interaction. Psychological game theory, based on nonstandard assumptions, is required to solve these problems, and some suggestions along these lines have already been put forward. Key Words: backward induction; Centipede game; common knowledge; cooperation; epistemic reasoning; game theory; payoff dominance; pure coordination game; rational choice theory; social dilemma.

This paper written as a dialogue between two interlocutors, Julie and a Student, deals with Understanding and its role in the social sciences. The fictional dialogue takes place in Hannover, Germany, and the interlocutors are exchanging arguments about Verstehen and how it should be conceptualized in the philosophy of the social sciences. A range of different approaches is discussed and a naturalistic strategy emerges as a defensible alternative.

Nous tentons, dans cet article, de déterminer la place des comportements non conséquentialistes, notamment le respect des valeurs et des normes, dans la théorie du choix rationnel. Au départ, il n’y a pas de limites à ce qui peut constituer une préférence ou une valeur d’utilité; tout comportement non conséquentialiste peut être réduit à un comportement conséquentialiste. Un bref examen de certains modèles rationnels des normes sociales nous montre, d’une part, que la réduction conséquentialiste du conformisme laisse inexpliqués certains phénomènes (...) importants, et d’autre part, que l’emploi d’utilités autres qu’instrumentales pose de sérieux problèmes à la théorie. Pour terminer, nous discutons de deux autres approches de la théorie du choix rationnel faisant une large part aux comportements non conséquentialistes. Nous concluons que si, pour une même action, le type de motivation influence en soi les résultats de l’action collective, alors il nous faut dans ce cas sortir du cadre de la rationalité, sans toutefois complètement l’abandonner.In this paper, we attempt to find the place of non-consequentialist behavior, like respect of norms and values, in rational-choice theory. At the onset, there is no limit as to what can constitute a preference or a utility value; any non-consequentialist behavior can be reduced to a consequentialist one. A brief survey of several rational models of social norms shows us, on one hand, that consequentialist reduction of conformity leaves some important phenomena unexplained, and, on the other hand, that recourse to non-instrumental utilities generates serious problems within the theory. We end with a discussion of two alternative approaches to rational-choice theory that leave a large place for non-consequentialist behavior. We conclude by saying that if, for the same action, the type of motivation behind it has by itself an influence on the outcome of collective action, then in such cases we have to step out of rational-choice theory, without however abandoning it.

In discussions of practical reason we often encounter the view that a fact is a reason for an agent to act only if the fact is capable of moving the agent to act. This view figures centrally in many philosophical controversies, and while taken for granted by some, it is vigorously disputed by others. In this essay I show that if the disputed position is correctly interpreted, it is well armored against stock objections and implied by a premise that is (...) not only plausible, but generally accepted by the position's critics.

This commentary focuses on the parts of psychological game theory dealing with preference, as illustrated by team reasoning, and supports the conclusion that these theoretical notions do not contribute above and beyond existing theory in understanding social interaction. In particular, psychology and games are already bridged by a comprehensive, formal, and inherently psychological theory, interdependence theory (Kelley & Thibaut 1978; Kelley et al. 2003), which has been demonstrated to account for a wide variety of social interaction phenomena.

A traditional objection to coherentism is that there may be incompatible though equally coherent sets of beliefs. The purpose of the paper is to assess this objection. It is argued that the better a belief "p" coheres with the system of a person, the less likely it is that the negation of the belief coheres equally well with someone else's system, or even that there is someone else who believes the negation of "p". The arguments are based on two plausible (...) assumptions about coherence, and some more controversial assumptions concerning meaning and interpretation. (shrink)

This article examines two empirical research traditions—experimental economics and the social identity approach in social psychology—that may be seen as attempts to falsify and verify the theory of collective intentionality, respectively. The article argues that both approaches fail to settle the issue. However, this is not necessarily due to the alleged immaturity of the social sciences but, possibly, to the philosophical nature of intentionality and intentional action. The article shows how broadly Davidsonian action theory, including Hacking’s notion of the looping (...) effect of the human sciences, can be developed into an argument for the view that there is no theory-independent true nature of intentional action. If the Davidsonian line of thought is correct, the theory of collective intentionality is, in a sense, true if we accept the theory. Key Words: collective intentionality • experimental economics • social identity theory • Donald Davidson • Ian Hacking • constructivism • action • agency • philosophy of the social sciences.

A key assumption in the person-oriented approach is that a person must be understood as a complex, integrated system, represented by patterns of within-person variation rather than scores on separate variables. The term ‘system’ does, however, have multiple meanings, which are not clearly distinguished in the person-oriented literature. I try to disentangle causal interactionism, which describes the psychological consequences and functions of each component of the system as dependent upon its causal interaction with other system components, from content holism, which (...) describes the system components as in part constituted by their relations to each other and the system as a whole. Although the terms ‘interactionism’ and ‘holism’ are often treated as combinable and interchangeable, causal interactionism and content holism pertain to distinct kinds of research problems. Causal interactionism construes the person in terms of the hierarchically structured mechanistic systems that underpin his or her attributes and shape them over time, and can be exemplified in terms of Magnusson’s developmental approach, whereas content holism is integral to our understanding of the person as an intentional system, whose mental states and actions are interweaved through principles or logic and rationality rather than material causality, and can be exemplified in terms of Stephenson’s Q-methodological approach.

The article raises objections to some fundamental assumptions of ?normative naturalism? as put forth by Larry Laudan. It contests the view that matters of rationality are strictly to be separated from matters of (normative) methodology and progress of knowledge. Thus a modified version of what Laudan calls the ?historicist's meta?methodology thesis? is suggested. In particular, it is argued that methodological rules should not initially be taken as elliptical for hypothetical means?end relations. Assuming that they are taken as such, it is (...) argued that naturalized methodology becomes untestable, since methodological rules (norms) turn out to be either vacuous or not lawlike. It is suggested that methodological norms have a status which has much in common with social norms. Instead of starting with methodological instrumentalities, a view of methodology is sketched in which the traditional idea of rational reconstruction is utilized. Yet the history of science may still serve as a major warrant for normative methodological claims. This becomes possible once we accept John Rawls's justificationary strategy of a ?reflective equilibrium?. Finally, it is claimed that Laudan's misconception of methodology is in part due to an inadequate notion of (scientific) progress. (shrink)
