Essay On The Value Of Sports And Games In Life (1)

So, do people's choices seem to reveal team-centredpreferences? Standard examples, including Bacharach's own, are drawnfrom team sports. Members of such teams are under considerable socialpressure to choose actions that maximize prospects for victory overactions that augment their personal statistics. The problem with theseexamples is that they embed difficult identification problems withrespect to the estimation of utility functions; a narrowlyself-interested player who wants to be popular with fans might behaveidentically to a team-centred player. Soldiers in battle conditionsprovide more persuasive examples. Though trying to convince soldiersto sacrifice their lives in the interests of their countries is oftenineffective, most soldiers can be induced to take extraordinary risksin defense of their buddies, or when enemies directly menace theirhome towns and families. It is easy to think of other kinds of teamswith which most people plausibly identify some or most of the time:project groups, small companies, local labor unions, clans andhouseholds. Strongly individualistic social theory tries to constructsuch teams as equilibria in games amongst individual people, but noassumption built into game theory (or, for that matter, mainstreameconomic theory) forces this perspective. We can instead suppose thatteams are often exogenously welded into being by complex interrelatedpsychological and institutional processes. This invites the gametheorist to conceive of a mathematical mission that consists not inmodeling team reasoning, but rather in modeling choice that isconditional on the existence of team dynamics.

The Tragedy of the Commons, by Garrett Hardin (1968)

This is not to suggest that the anthropological interpretation of theempirical results should be taken as uncontroversial. Binmore (, , , ) has argued for many years, based on a wide range of behavioral data,that when people play games with non-relatives they tend to learn toplay Nash equilibrium with respect to utility functions thatapproximately correspond to income functions. As he points out in , Henrich et al.'s data do not test this hypothesis for theirsmall-scale societies, because their subjects were not exposed to thetest games for the (quite long, in the case of the Ultimatum game)learning period that theoretical and computational models suggest arerequired for people to converge on NE. When people play unfamiliargames, they tend to model them by reference to games they are used toin everyday experience. In particular, they tend to play one-shotlaboratory games as though they were familiar repeated games,since one-shot games are rare in normal social life outside of specialinstitutional contexts. Many of the interpretive remarks made byHenrich et al. are consistent with this hypothesis concerningtheir subjects, though they nevertheless explicitly reject the hypothesisitself. What is controversial here—the issues of spin around‘orthodox' theory aside—is less about what theparticular subjects in this experiment were doing than about whattheir behavior should lead us to infer about human evolution.

We have now seen the first level at which neuroeconomics applies gametheory. A second level involves seeking conditioning variables inneural activity that might impact people's choices of strategies whenthey play games. This has typically involved repeating protocols fromthe behavioral game theory literature with research subjects who arelying in fMRI scanners during play. and have argued forskepticism about the value of work of this kind, which involvesvarious uncomfortably large leaps of inference in associating theobserved behavior with specific imputed neural responses. It can alsobe questioned whether much generalizable new knowledge is gained tothe extent that such associations can be successfullyidentified.

Requirement (b) as a constraint on game-theoretic modeling of generalhuman strategic dispositions is no longer very controversial —or, at least, is no more controversial than the generic adaptationismin evolutionary anthropology of which it is one expression. However,some commentators are skeptical of Gintis's suggestion that there wasa genetic discontinuity in the evolution of human sociality. (For acognitive-evolutionary anthropology that explicitly denies suchdiscontinuity, see .) Based partly on such skepticism (but more directly on behavioraldata) Binmore (, ) resists modeling people as having built-in preferences foregalitarianism. According to Binmore's (, , ) model,the basic class of strategic problems facing non-eusocialsocial animals are coordination games. Human communities evolvecultural norms to select equilibria in these games, and many of theseequilibria will be compatible with high levels of apparentlyaltruistic behavior in some (but not all) games. Binmore argues thatpeople adapt their conceptions of fairness to whatever happen to betheir locally prevailing equilibrium selection rules. However, hemaintains that the dynamic development of such norms must becompatible, in the long run, with bargaining equilibria amongself-regarding individuals. Indeed, he argues that as societies evolveinstitutions that encourage what Henrich et al. callaggregate market integration (discussed above), their utilityfunctions and social norms tend to converge on self-regarding economicrationality with respect to welfare. This does not mean that Binmoreis pessimistic about the prospects for egalitarianism: he develops amodel showing that societies of broadly self-interested bargainers can be pullednaturally along dynamically stable equilibrium paths towards norms ofdistribution corresponding to Rawlsian justice (). The principal barriers to such evolution, according to Binmore, areprecisely the kinds of other-regarding preferences that conservativesvalorize as a way of discouraging examination of more egalitarianbargaining equilibria that are within reach along societies'equilibrium paths.

Given the unresolved complex relationship between learning theory andgame theory, the reasoning above might seem to imply that game theorycan never be applied to situations involving human players that arenovel for them. Fortunately, however, we face no such impasse. In apair of influential papers in the mid-to-late 1990s, McKelvey andPalfrey (, )developed the solution concept of quantal responseequilibrium (QRE). QRE is not a refinement of NE, in the sense ofbeing a philosophically motivated effort to strengthen NE by referenceto normative standards of rationality. It is, rather, a method forcalculating the equilibrium properties of choices made by playerswhose conjectures about possible errors in the choices of otherplayers are uncertain. QRE is thus standard equipment in the toolkitof experimental economists who seek to estimate the distribution ofutility functions in populations of real people placed in situationsmodeled as games. QRE would not have been practically serviceable inthis way before the development of econometrics packages such as Stata(TM) allowed computation of QRE given adequately powerful observationrecords from interestingly complex games. QRE is rarely utilized bybehavioral economists, and is almost never used by psychologists, inanalyzing laboratory data. In consequence, many studies by researchersof these types make dramatic rhetorical points by‘discovering’ that real people often fail to converge onNE in experimental games. But NE, though it is a minimalist solutionconcept in one sense because it abstracts away from much informationalstructure, is simultaneously a demanding empirical expectation if itimposed categorically (that is, if players are expected to play as ifthey are all certain that all others are playing NEstrategies). Predicting play consistent with QRE is consistentwith—indeed, is motivated by—the view that NE captures thecore general concept of a strategic equilibrium. One way of framingthe philosophical relationship between NE and QRE is as follows. NEdefines a logical principle that is well adapted fordisciplining thought and for conceiving new strategies for genericmodeling of new classes of social phenomena. For purposes ofestimating real empirical data one needs to be able to defineequilibrium statistically. QRE represents one way of doingthis, consistently with the logic of NE.

Prior to the work of , situations of this sort were inherently baffling to analysts. This isbecause utility does not denote a hidden psychological variable suchas pleasure. As we discussed in , utility is merely a measure of relative behavioural dispositionsgiven certain consistency assumptions about relations betweenpreferences and choices. It therefore makes no sense to imaginecomparing our players' cardinal—that is,intensity-sensitive—preferences with one another's, since thereis no independent, interpersonally constant yardstick we coulduse. How, then, can we model games in which cardinal information isrelevant? After all, modeling games requires that all players'utilities be taken simultaneously into account, as we've seen.
