Markets and Prosociality
This entry explores the complex relationship between market interactions and prosocial behavior, examining how economic systems may both foster and inhibit cooperation, trust, and fairness from an evolutionary perspective. It investigates the psychological mechanisms that underpin prosociality in market contexts and the conditions under which markets might select for or against such traits.
The relationship between market exchange and prosocial behavior is a central topic in evolutionary psychology, as markets represent a pervasive form of human interaction that involves both cooperation and competition. Prosociality, broadly defined as behavior intended to benefit others, includes altruism, fairness, trust, and cooperation. Understanding how these traits manifest and are influenced within market settings provides insight into the co-evolution of human psychology and economic systems.
The Argument for Markets Fostering Prosociality
Several arguments suggest that market interactions can promote prosociality. One perspective, articulated by scholars like Henrich (2015), posits that participation in large-scale, anonymous markets requires and selects for generalized trust and fairness. In traditional small-scale societies, prosociality often operates through direct reciprocity or kin selection, where interactions are repeated and individuals know each other. However, modern markets involve transactions with strangers, often without immediate reputational consequences or kinship ties. For these systems to function efficiently, individuals must develop a generalized propensity to trust others and adhere to norms of fair exchange, even when defection might offer short-term gains. This is often framed as a form of indirect reciprocity or generalized reciprocity, where individuals behave prosocially because it maintains a reputation that benefits them in future, unknown interactions, or because they have internalized norms that facilitate market functioning.
Experimental economics provides some support for this view. Studies using games like the Ultimatum Game, Dictator Game, and Trust Game across diverse cultures have shown significant variation in prosocial behavior, with participants from societies with more extensive market integration often exhibiting higher levels of fairness and trust (Henrich et al., 2001). For example, groups with greater market integration tend to offer larger shares in the Ultimatum Game and demonstrate higher levels of trust in the Trust Game. This suggests that the cognitive and emotional adaptations for navigating complex, anonymous exchanges may involve an enhanced capacity for generalized prosociality.
Another mechanism is the development of institutions that enforce contracts and property rights. While not strictly a psychological adaptation, the existence of such institutions reduces the risk of defection and allows individuals to engage in more complex and beneficial exchanges. The institutional co-evolution hypothesis suggests that human psychological predispositions for cooperation and the development of formal and informal institutions are mutually reinforcing, leading to more robust market systems that can support larger populations (Richerson & Boyd, 2005).
The Argument for Markets Inhibiting Prosociality
Conversely, some evolutionary psychologists and economists argue that market environments can undermine certain forms of prosociality, particularly by emphasizing self-interest and competition. The classical economic model often assumes individuals are rational utility maximizers, acting solely to maximize their own gains. While this is a simplification, the homo economicus model can influence behavior by shaping expectations and social norms. When individuals perceive that self-interested behavior is expected or rewarded in market contexts, their own prosocial tendencies may be suppressed.

- The Moral AnimalRobert Wright · 1994Foundational text
This foundational book explores the evolutionary roots of human morality, cooperation, and social behavior, providing a broad framework for understanding how natural selection shaped our psychological predispositions, which are then expressed in various social contexts, including economic ones.
- A Cooperative SpeciesSamuel Bowles, Herbert Gintis · 2011Canonical academic monograph
This book offers a rigorous, interdisciplinary account of how humans evolved to be a cooperative species, integrating insights from economics, biology, and anthropology. It directly addresses how institutions and markets can shape and be shaped by our prosocial tendencies.
- The Secret of Our SuccessJoseph Henrich · 2016Recent synthesis
Henrich argues that culture, and particularly our capacity for cumulative cultural learning, is central to human success. He explores how institutions like markets foster generalized trust and cooperation, providing a direct link to the article's discussion of market-driven prosociality.
- The Evolution of CooperationRobert Axelrod · 1984Field-defining work
A classic in game theory, this book demonstrates how cooperation can emerge and persist even among self-interested individuals through repeated interactions. Its insights into reciprocity and reputation are crucial for understanding the dynamics of trust and fairness in market settings.

- Adaptationist Accounts of ReligionAdaptationist accounts of religion propose that religious beliefs and practices, or the psychological mechanisms that give rise to them, are adaptations that evolved due to their fitness benefits for individuals or groups. These theories contrast with by-product explanations, which view religion as an incidental outcome of cognitive architecture evolved for other purposes.
- Afterlife BeliefsAfterlife beliefs refer to the conviction that some aspect of an individual's consciousness or identity persists beyond physical death. Evolutionary psychology investigates the cognitive mechanisms and social functions that may have contributed to the widespread prevalence and persistence of such beliefs across diverse human cultures.
- Big Gods HypothesisThe Big Gods hypothesis proposes that belief in powerful, morally concerned, and omniscient deities evolved as a mechanism to foster large-scale cooperation and prosociality among genetically unrelated individuals, thereby facilitating the emergence and stability of complex societies. It suggests that such beliefs served to enforce moral norms and deter free-riding, particularly in contexts where direct monitoring was impractical.
- Born-Believers HypothesisThe born-believers hypothesis posits that humans possess innate cognitive biases and mechanisms that predispose them to religious belief, rather than religion being solely a product of cultural learning. This perspective suggests that certain aspects of religious thought emerge as byproducts of evolved cognitive architecture designed for other adaptive functions.
- By-product Accounts of ReligionBy-product accounts of religion propose that religious beliefs and practices are not direct adaptations for specific functions but rather emergent consequences of cognitive mechanisms that evolved for other, non-religious purposes. This perspective views religion as an incidental outcome of ordinary mental faculties operating in specific social and environmental contexts.
- Cooperation at ScaleCooperation at scale refers to the human capacity for large-group cooperation, extending beyond kin and reciprocal dyads, which is a distinctive feature of human societies. This phenomenon is central to understanding the evolution of complex social structures and institutions.
