  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 (...)

    Interethnic Interaction, Strategic Bargaining Power, and the Dynamics of Cultural Norms.John Andrew Bunce & Richard McElreath - 2017 - Human Nature 28 (4):434-456.
    Ethnic groups are universal and unique to human societies. Such groups sometimes have norms of behavior that are adaptively linked to their social and ecological circumstances, and ethnic boundaries may function to protect that variation from erosion by interethnic interaction. However, such interaction is often frequent and voluntary, suggesting that individuals may be able to strategically reduce its costs, allowing adaptive cultural variation to persist in spite of interaction with out-groups with different norms. We examine five mechanisms influencing the dynamics (...)

  3. 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 (...)

    Ontogeny of prosocial behavior across diverse societies.Bailey R. House, Joan B. Silk, Joseph Henrich, H. Clark Barrett, Brooke A. Scelza, Adam H. Boyette, Barry S. Hewlett, Richard McElreath & Stephen Laurence - 2013 - Proceedings of the National Academy of Sciences of the United States of America 110 (36):14586-14591.
    Humans are an exceptionally cooperative species, but there is substantial variation in the extent of cooperation across societies. Understanding the sources of this variability may provide insights about the forces that sustain cooperation. We examined the ontogeny of prosocial behavior by studying 326 children 3–14 y of age and 120 adults from six societies (age distributions varied across societies). These six societies span a wide range of extant human variation in culture, geography, and subsistence strategies, including foragers, herders, horticulturalists, and (...)

    Using Multilevel Models to Estimate Variation in Foraging Returns.Richard McElreath & Jeremy Koster - 2014 - Human Nature 25 (1):100-120.
    Distributions of human foraging success across age have implications for many aspects of human evolution. Estimating the distribution of foraging returns is complicated by (1) the zero-inflated nature of hunting returns, as many if not most trips fail, and (2) the substantial variation among hunters, independent of age. We develop a multilevel mixture analysis of human foraging data to address these difficulties. Using a previously published 20-year record of hunts by 147 individual Aché hunters in eastern Paraguay, we estimate returns-by-age (...)

    Strategies for advice taking: The role of epistemic social information.Annika Wallin & Richard McElreath - 2015 - Economics and Philosophy 31 (1):67-91.
    How does an individual decision maker update his or her beliefs in the light of others’ beliefs? We present an empirical investigation that varies decision makers’ access to other peoples’ beliefs: whether they know what course of action others have taken and whether they know why this course of action was taken.We propose a number of process models of advice taking that do and do not accommodate the reasons given for belief, and evaluate which is used through model comparison techniques.

    The evolutionary rationality of social learning.Richard McElreath, Annika Wallin & Barbara Fasolo - 2013 - In Ralph Hertwig & Ulrich Hoffrage (eds.), Simple Heuristics in a Social World. Oxford University Press.
    We have analyzed the long-term success of various social learning heuristics. Specifically, we have examined their ability to persist and to replace other heuristics, and we have done this in two broadly different kinds of environments: environments in which the optimal behavior varies across space, or through time. Because each social learning heuristic also shapes its environment as individuals use it, our analysis has been at the same time ecological, game-theoretic, and evolutionary: The performance of each social learning heuristic depends (...)

    The only thing that can stop bad causal inference is good causal inference.Julia M. Rohrer, Stefan C. Schmukle & Richard McElreath - 2022 - Behavioral and Brain Sciences 45.
    In psychology, causal inference – both the transport from lab estimates to the real world and estimation on the basis of observational data – is often pursued in a casual manner. Underlying assumptions remain unarticulated; potential pitfalls are compiled in post-hoc lists of flaws. The field should move on to coherent frameworks of causal inference and generalizability that have been developed elsewhere.
