    The Origin of Prosociality Toward Strangers
    (2013) Tan, Jingzhi

    Humans are champions of prosociality. Across different cultures and early in life, humans routinely engage in prosocial behaviors that benefit others. Perhaps most strikingly, humans are even prosocial toward strangers (i.e. xenophilic). This is an evolutionary puzzle because it cannot be explained by kinship theory, reciprocal altruism or reputation. The parochialism hypothesis proposes that this extreme prosociality is unique to humans, is motivated by unselfish motivation and evolved through group selection made possible by human culture and warfare. The first impression hypothesis, on the other hand, proposes that xenophilia can evolve to promote the selfish benefits that accrue from extending one's social network. It predicts that 1) nonhuman species can evolve prosociality toward strangers when the benefit of forming new relations is higher than the cost, 2) the motivation for prosociality can be selfish, and 3) encounters with strangers can be a positive social event since strangers represent potential social partners. This dissertation presents three sets of experiments designed to test these predictions with bonobos (Pan paniscus), a species known for reduced xenophobia. These experiments showed, first, that bonobos voluntarily shared monopolizable food with a stranger and helped the stranger to obtain out-of-reach food. Second, the observed prosociality was driven by a selfish motivation to initiate an interaction with the stranger in close proximity and an other-regarding motivation to benefit the stranger. Third, an involuntary yawning task and a voluntary choice task show converging results that bonobos attribute positive valence to completely unknown strangers by default. These experiments support the three core predictions of the first impression hypothesis and challenge the view that intergroup competition is crucial to the origin of prosociality toward strangers in our species. Instead, the first impression hypothesis proposes that xenophilia in bonobos is probably an adaptation to initiating non-kin cooperation. Because female bonobos are highly cooperative even though they are the dispersing sex, xenophilia might function to quickly establish cooperative relationships with new immigrants. This suggests that xenophilia and reciprocity are likely two complementary aspects of non-kin cooperation: the former explains its initiation while the latter explains its maintenance. Similarly, xenophilia in humans is likely a result of the increasing need for cooperation among non-kin due to enhanced fission-fusion dynamics, population expansion, obligate cooperative foraging and greater dependence on cultural knowledge.

    Topics in Rational Choice Theory
    (2008-04-29) Akhtar, Sahar Z
    Rational Choice theory includes a broad body of research that attempts to account for how people act in a variety of contexts, including economic, political and even moral situations. By proposing, most generally, that individuals rationally pursue their self-interests regardless of the context, rational choice has had extensive theoretical and empirical success, on the one hand, and has also faced wide criticism when applied in a variety of disciplines, on the other hand. While there is disagreement over what the defining assumptions of rational choice theory are, in this dissertation I focus on three on which there is widespread agreement. These three features of rational choice theory are: its assumption of egoism or self-interest as the central motivation of individuals; its reliance on consequences as part of a comparative decision-making framework; and finally, its focus on the individual and not on groups as the methodological and normative unit of analysis. In correspondence to these three features, my dissertation is divided into three parts and explores the separate topics of (I) egoism and altruism; (II) consequentialism and ethical decision-making; and, (III) individualism and group identity. The dissertation is not an exercise in showing the extensive problems of rational choice theory, although there are many. The dissertation rather engages these three topics with differing results, some of which in fact attempts to revitalize rational choice, or at least features of rational choice. For the part on altruism, my goal is to demonstrate why the central assumption of egoism in rational choice theory is problematic. More broadly, I argue for a different way of defining genuine altruistic motivation. A result of my analysis there is that altruism appears to be more widespread than has been traditionally assumed and is more amenable to empirical examination. For my discussion on consequentialism, my aim is to re-characterize rational choice as a mode of moral decision-making. I argue that the moral agent is one who frequently compares her particular moral ends in a stable fashion and for this reason cost-benefit analysis is a fully moral framework, one that encourages the agent to genuinely care for her ends and values. For the topic of individualism and group identity, my objective is to show how a previously dismissed topic, once unpacked, is fully consistent with rational choice theory and ought to be of interest to the rational choice theorist. I show that if the liberal political theorist, including the rational choice theorist, is to value group identity, the commitment is only limited to valuing a form of group identity--particularized identity--that is individualist in character.
