According to John Searle's theory of human ontology, intentional mental states such as beliefs and wants rely on non-intentional, Background, dispositions to produce rational behaviour. The distinction between intentional and non-intentional states is used as the basis on which to understand the various conceptions of human agency to be found in behavioural finance. The agent of behavioural finance is characterized in terms of three sets of psychological traits: prospect theory, heuristics and mental accounting. These are examined from a Searlean perspective (...) and shown to rely on the interplay between various reflected upon and non-reflected upon elements, in keeping with the Searlean human ontology previously considered. A number of implications are drawn from these findings. (shrink)

In the recent literature at the interface between economics, biology and neuroscience, several authors argue that by adopting an interdisciplinary approach to the analysis of decision making, economists will be able to construct predictively and explanatorily superior models. However, most economists remain quite reluctant to import biological or neural insights into their account of choice behaviour. In this paper, I reconstruct and critique one of the main arguments by means of which economists attempt to vindicate their conservative position. Furthermore, I (...) develop an alternative defense of the thesis that economists justifiably rely on a methodologically distinctive approach to the modelling of choice behaviour. (shrink)

The recent advancements at the interface between economics and neuroscience have encouraged neuroeconomists to raise several criticisms concerning the economic theory of choice. At present, however, there is little agreement with regard to the theoretical presuppositions and the explanatory aims of neuroeconomics. In this paper, I assess the scope and the significance of neuroeconomists' divergences, casting doubt on their attempts to provide a unified theoretical framework for analysing human choice behaviour. Moreover, I highlight some respects in which methodologically informed considerations (...) can promote the consolidation of the neuroeconomic enterprise. (shrink)

Abstract A number of empirical literatures in economics display the following pattern of results. First, evidence accumulates to support an empirical result. As time passes, however, contrary results emerge that challenge that initial result. This phenomenon raises important issues about (i) what part empirical findings play in how economists come to believe things; and (ii) how believable inferences are to be made from literatures displaying such contrary results. This paper documents this ?emerging contrary result? phenomenon, and investigates the factors causing (...) it. It considerably expands the list of emerging contrary results contained in my 1995 JEM paper. Of more importance, this paper identifies alternative explanations for these instances, and explores whether particular explanations can be plausibly assigned to the 26 examples in this paper.

Analytical philosophy has been challenged by experimental approaches that make use of, among other things, cognitive science methods. In this paper we illustrate the benefits of merging philosophy with neuroscience, using an example of research in the foundations of social science. We argue that designing novel experiments to answer specific philosophical questions has several advantages compared to relying passively on neuroscientists' data. In this particular case, the data redirect attention towards topics ? such as inductive reasoning ? that are relatively (...) overlooked by mainstream social neuroscience. (shrink)

We critically review the methodological practices of two research programs which are jointly called ?neuroeconomics?. We defend the first of these, termed ?neurocellular economics? (NE) by Ross (2008), from an attack on its relevance by Gul and Pesendorfer (2008) (GP). This attack arbitrarily singles out some but not all processing variables as unimportant to economics, is insensitive to the realities of empirical theory testing, and ignores the central importance to economics of ?ecological rationality? (Smith 2007). GP ironically share this (...) last attitude with advocates of ?behavioral economics in the scanner? (BES), the other, and better known, branch of neuroeconomics. We consider grounds for skepticism about the accomplishments of this research program to date, based on its methodological individualism, its ad hoc econometrics, its tolerance for invalid reverse inference, and its inattention to the difficulties involved in extracting temporally lagged data if people's anticipation of reward causes pre-emptive blood flow.

Many of the arguments for neuroeconomics rely on mistaken assumptions about criteria of explanatory relevance across disciplinary boundaries and fail to distinguish between evidential and explanatory relevance. Building on recent philosophical work on mechanistic research programmes and the contrastive counterfactual theory of explanation, we argue that explaining an explanatory presupposition or providing a lower-level explanation does not necessarily constitute explanatory improvement. Neuroscientific findings have explanatory relevance only when they inform a causal and explanatory account of the psychology of human decision-making.

In this paper I examine Don Ross’s application of unificationism as a methodological criterion of theory appraisal in economics and cognitive science. Against Ross’s critique that explanations of the preference reversal phenomenon by the ‘heuristics and biases’ programme is ad hoc or ‘Ptolemaic’, I argue that the compatibility hypothesis, one of the explanations offerd by this programme, is theoretically and empirically well-motivated. A careful examination of this hypothesis suggests several strengths of a procedural approach to modelling cognitive processes underlying individual (...) decision making, compared to a multiple-agent approach which Ross promotes. I argue that the debate between economists and psychologists are both theoretical and empirical, but cannot be resolved by appealing to the ideal of unification. (shrink)

I discuss the role of economics in the study of social cognition. A currently popular view is that microeconomics should collapse into psychology partly because cognitive science has shown that valuation is constitutively social, whereas non-psychological economics insists that it is not. In the paper I resist this view, partly by reference to the relevant history of economic theory, and partly by reference to an alternative model of the way in which that theory complements, without reducing to, psychological accounts of (...) social cognition.

Three recent book-length studies in the philosophy of economics (Mirowski 2002, Davis 2003, Ross 2005) have drawn attention to the fact that mainstream economic theory has consistently avoided commitment to any particular model of the person. This is the most significant respect in which economics has kept aloof from part of psychology. The widespread belief, on the other hand, that economists’ attentiveness to the psychology of choice and decision had to wait for the Allais challenge and then for Kahneman and (...) Tversky is a myth. It is true that for a brief period after World War II economists led by Samuelson tried to operationalize choice as analytically derivative from observed consumer demand. This was a minor episode in the history of theory. Ross (2005) argues that, if anything, mainstream microeconomics has been more sensitive to theoretical fashions in the psychology of choice than has been good for it. (shrink)

This paper argues that the most common reading of Robbins’s Essay on the Nature and Significance of Economic Science in the methodology literature, according to which it was an historical foil for subsequent positivist-empiricist ideas, underestimates its contemporary relevance. In light of recent scholarship on 1930s positivism in philosophy, Robbins’s Essay is better interpreted as representing an attitude I call ‘broad positivism’, which remains a live option in contemporary philosophy of science. In consequence, the basis of Robbins’s preference for clear (...) demarcation between economics and psychology should be regarded as not merely historical in interest, but as raising valid considerations against the widespread current trend towards ‘correcting’ aspects of economic theory by reference to psychological experiments.

Critics of mainstream economics typically rest important weight on the differences between people and the 'agents' that populate economic theory and economic models. Hollis and Nell (1975) is both representative of and ancestral to many more recent variations on the theme. Lately, the upgraded status of behavioral economics (BE) within the discipline's mainstream has encouraged a number of writers to use revolutionary rhetoric in promotion of a 'paradigm shift' that includes the rejection of 'rational economic man' (Ormerod 1994, Heilbroner and (...) Milburg 1995, Fullbrook 2003). The current leading developers of BE are generally more circumspect, claiming that their approach complements standard theory rather than promising to supplant it (Camerer and Loewenstein 2004, Angner and Loewenstein this volume). However, they generally join the more florid critics in supposing that microeconomics is bound to improve its empirical relevance to the extent that it substitutes the study of people for that of abstract economic agents. Another body of thought that promotes this view stems from Sen's (1977) attack on standard economic agents as 'rational fools', amplified in Davis's (2003) argument that since economic agents lack some essential properties of human individuals, economic theory requires fundamental reform if it is to make progress in explaining human behavior.
