Wood USA Edith Cowan University, Australia xi TWO RELATIONAL CONCEPTIONS OF INDIVIDUALS: TEAMS AND NEUROECONOMICS John B. Davis I have argued that taking atomistic individuals to be interactive beings in some way or another does not produce an adequate conception of the individual, because the subjectivism of these approaches does not permit interaction to overcome the deep problems in the atomistic conception (Davis,2003).Suppose,then,thatindividualsaredefinedfromtheoutsetas interactive beings, rather than as atomistic individuals who are secondarily interactive.

DAVIS accounts encounter concerns the re-identification problem or how you re- identify a person shown to be individual across change in that individual’s characteristics. Internalist accounts of the individual do not even get to this problem, because they cannot individuate persons in the first place. For externalist relational accounts, re-identification is a problem if persons are individuated narrowly in terms of particular social relationships that are transitory. Persons who are individuated in terms of one set of social relationships may not be in terms of another set; that is, those social relationships that are individuating may not be long-lasting. Thus, relational conceptionscanovercomesomeofthedifficultiesoftheatomisticconception but end up still not being adequate to our ordinary view of individuals as enduring beings. In part, the recent relational approaches to the individual have been inspired by problems in standard decision theory and associated doubts about the atomistic individual conception. But there is also an empirical foundation for these alternative approaches in the Easterlin paradox and thevoluminousliteraturethathasfollowedinthepastthreedecades.Using individuals’ subjective self-evaluations of happiness, Richard Easterlin argued that cross-sectional country data and within-country time-series showthatthereisnoclearrelationbetweenwealthandhappiness(Easterlin, 1974,2001).Ashasbeendemonstratedmanytimessince,happinessappears to rise with income and wealth until basic needs are met, and thereafter greater income and wealth appear to have little or diminishing effect on happiness (Layard, 2005). But more important, not only are ‘‘the effects of wealth are not large ... [but] they are dwarfed by other influences, such as those of personality and social relationships’’ (Diener & Seligman, 2003, p. 10). Indeed, Easterlin originally attempted to explain his results as James Duesenberry(1949)hadusingarelativeincomehypothesis,andothershave proposed relative consumption hypotheses, both of which emphasize the role of social relationships (Scitovsky, 1976; Hirsch, 1977; Frank, 2005). Happiness or being happy, of course, is not the same thing as being an individual, but as happiness surveys are the product of individuals’ subjective self-evaluations of happiness, happiness is closely connected to one’s sense of being an individual. Thus, since social relationships are an important source of happiness, we have good reason to investigate individuals from a relational perspective. But what does a relational conception of individuals involve? Outside of being a departure from the atomistic conception, there is obviously considerable ambiguity regarding what ‘‘relational’’ can mean, though one thing is clearly that it bases the account of the individual on social Two Relational Conceptionsof Individuals 3 interaction. Accordingly, this chapter seeks to examine two representative views within this general framework. In the first section, I begin with theoriesofteamsandteamreasoningthatusesocialidentitytheoryandare developedwithinagame-theoreticframework.Thesecondsectionmoveson to game-theoretic neuroeconomic accounts of the individual and distin- guishestwodifferenttypesofrelationalconceptionoftheindividual.Abrief conclusion closes the paper. TEAMS AND TEAM REASONING Recentworkonthetheoryofteamsandteamreasoningingameinteractive settingsisdueprincipallytothelateMichaelBacharach(Bacharach,2006), who offers a conception of the individual as a team member, and also to Martin Hollis (1998) and Robert Sugden and Natalie Gold (Sugden, 2000; Gold & Sugden, 2007), and is motivated by the conflict between what ordinary experience suggests people often to do and what rationality pre- scribesforthem,suchasinprisoner’sdilemmagameswhereindividualscan choosetocooperateordefect.Thesourceoftheconflict,theysuggest,isan ambiguityinthesyntaxofstandardgametheory,whichistakentoposethe question individuals in games ask themselves as, ‘‘what should I do?,’’ but which might be taken to pose the question, particularly when individuals are working together with others as, ‘‘what should we do?’’ When taken in thelatterway,eachindividualchoosesaccordingtowhatbestpromotesthe team’sobjectiveandthenperformstheroleappropriateasamemberofthat team or group. Bacharach understood this change in focus in terms of the different possible cognitive frames that individuals use to think about the world and developed a variable frame theory for rational play in games in which the frame adopted fora decision problem determines what counts as rational play (Janssen, 2001; Casajus, 2001).
