  1. “Economic Man” in Cross-Cultural Perspective: Behavioral Experiments in 15 Small-Scale Societies.Joseph Henrich, Robert Boyd, Samuel Bowles, Colin Camerer, Ernst Fehr, Herbert Gintis, Richard McElreath, Michael Alvard, Abigail Barr, Jean Ensminger, Natalie Smith Henrich, Kim Hill, Francisco Gil-White, Michael Gurven, Frank W. Marlowe & John Q. Patton - 2005 - Behavioral and Brain Sciences 28 (6):795-815.
    Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of (...)

    Small-Scale Societies Exhibit Fundamental Variation in the Role of Intentions in Moral Judgment.H. Clark Barrett, Alexander Bolyanatz, Alyssa N. Crittenden, Daniel M. T. Fessler, Simon Fitzpatrick, Michael Gurven, Joseph Henrich, Martin Kanovsky, Geoff Kushnick, Anne Pisor, Brooke A. Scelza, Stephen Stich, Chris von Rueden, Wanying Zhao & Stephen Laurence - 2016 - Proceedings of the National Academy of Sciences 113 (17):4688–4693.
    Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Al- though these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence (...)

    To Give and to Give Not: The Behavioral Ecology of Human Food Transfers.Michael Gurven - 2004 - Behavioral and Brain Sciences 27 (4):543-559.
    The transfer of food among group members is a ubiquitous feature of small-scale forager and forager-agricultural populations. The uniqueness of pervasive sharing among humans, especially among unrelated individuals, has led researchers to evaluate numerous hypotheses about the adaptive functions and patterns of sharing in different ecologies. This article attempts to organize available cross-cultural evidence pertaining to several contentious evolutionary models: kin selection, reciprocal altruism, tolerated scrounging, and costly signaling. Debates about the relevance of these models focus primarily on the extent (...)

    Determinants of Time Allocation Across the Lifespan.Michael Gurven & Hillard Kaplan - 2006 - Human Nature 17 (1):1-49.
    This paper lays the groundwork for a theory of time allocation across the life course, based on the idea that strength and skill vary as a function of age, and that return rates for different activities vary as a function of the combination of strength and skills involved in performing those tasks. We apply the model to traditional human subsistence patterns. The model predicts that young children engage most heavily in low-strength/low-skill activities, middle-aged adults in high-strength/high-skill activities, and older adults (...)

    Models of Decision-Making and the Coevolution of Social Preferences.Joseph Henrich, Robert Boyd, Samuel Bowles, Colin Camerer, Ernst Fehr, Herbert Gintis, Richard McElreath, Michael Alvard, Abigail Barr, Jean Ensminger, Natalie Smith Henrich, Kim Hill, Francisco Gil-White, Michael Gurven, Frank W. Marlowe, John Q. Patton & David Tracer - 2005 - Behavioral and Brain Sciences 28 (6):838-855.
    We would like to thank the commentators for their generous comments, valuable insights and helpful suggestions. We begin this response by discussing the selfishness axiom and the importance of the preferences, beliefs, and constraints framework as a way of modeling some of the proximate influences on human behavior. Next, we broaden the discussion to ultimate-level (that is evolutionary) explanations, where we review and clarify gene-culture coevolutionary theory, and then tackle the possibility that evolutionary approaches that exclude culture might be sufficient (...)

    Reservation Food Sharing Among the Ache of Paraguay.Michael Gurven, Wesley Allen-Arave, Kim Hill & A. Magdalena Hurtado - 2001 - Human Nature 12 (4):273-297.
    We describe food transfer patterns among Ache Indians living on a permanent reservation. The social atmosphere at the reservation is characterized by a larger group size, a more predictable diet, and more privacy than the Ache typically experience in the forest while on temporary foraging treks. Although sharing patterns vary by resource type and package size, much of the food available at the reservation is given to members of just a few other families. We find significant positive correlations between amounts (...)

    A Bioeconomic Approach to Marriage and the Sexual Division of Labor.Michael Gurven, Jeffrey Winking, Hillard Kaplan, Christopher von Rueden & Lisa McAllister - 2009 - Human Nature 20 (2):151-183.
    Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other. We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This (...)

    When the Strong Punish: Why Net Costs of Punishment Are Often Negligible.Christopher R. von Rueden & Michael Gurven - 2012 - Behavioral and Brain Sciences 35 (1):43-44.
    In small-scale societies, punishment of adults is infrequent and employed when the anticipated cost-to-benefit ratio is low, such as when punishment is collectively justified and administered. In addition, benefits may exceed costs when punishers have relatively greater physical and social capital and gain more from cooperation. We provide examples from the Tsimane horticulturalists of Bolivia to support our claims.

    The Social Strategy Game.Stacey L. Rucas, Michael Gurven, Hillard Kaplan & Jeffrey Winking - 2010 - Human Nature 21 (1):1-18.
    This paper examines social determinants of resource competition among Tsimane Amerindian women of Bolivia. We introduce a semi-anonymous experiment (the Social Strategy Game) designed to simulate resource competition among women. Information concerning dyadic social relationships and demographic data were collected to identify variables influencing resource competition intensity, as measured by the number of beads one woman took from another. Relationship variables are used to test how the affiliative or competitive aspects of dyads affect the extent of prosociality in the game. (...)

    Tolerated Reciprocity, Reciprocal Scrounging, and Unrelated Kin: MaKing Sense of Multiple Models.Michael Gurven - 2004 - Behavioral and Brain Sciences 27 (4):572-579.
    Four models commonly employed in sharing analyses (reciprocal altruism [RA], tolerated scrounging [TS], costly signaling [CS], and kin selection [KS]) have common features which render rigorous testing of unique predictions difficult. Relaxed versions of these models are discussed in an attempt to understand how the underlying principles of delayed returns, avoiding costs, building reputation, and aiding biological kin interact in systems of sharing. Special attention is given to the interpretation of contingency measures that critically define some form of reciprocal altruism.

    An Evolutionary Perspective Can Help Unify Disparate Accounts of Grandparental Investment.Michael Gurven & Eric Schniter - 2010 - Behavioral and Brain Sciences 33 (1):25-26.
    Coall & Hertwig (C&H) bring attention to alternative accounts of grandparental investment from economics, evolutionary anthropology, psychology, and sociology, which have yet to be reconciled. We attempt to help integrate some of the disparate perspectives by expanding the scope of the evolutionary perspective, highlighting some gaps, and discussing problems with the authors' treatment of grandparents in traditional societies.
