Dora Costa, Matthew Kahn – Heroes, Cowards, and Beyond

Dora Costa, Matthew Kahn: UCLAIn Heroes and Cowards: The Social Face of War we used the life histories of more than forty thousand Civil War soldiers to discover when people are willing to sacrifice for the common good, what are the benefits of friendship, and what are the costs and benefits of being in a […]

Alyssa Crittenden – The ontogeny of prosocial behavior: foraging and food sharing among Hadza hunter-gatherer children

Alyssa Crittenden: UNLVHuman prosociality is one of the defining characteristics of our species, yet the developmental origins of altruistic behavior remain little understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing […]

Andrew Shtulman – Cognitive constraints on the understanding and acceptance of evolution

Andrew Shtulman: OccidentalEvolution by natural selection is a theory that has unified the biological sciences but divided the general public. In this talk, I shall discuss how early-emerging, essentialist constraints on the conceptualization of biological kinds impedes learning about population-level phenomena like evolution and natural selection. Data from cognitive studies (Shtulman, 2006), developmental studies (Shtulman […]

Robin Nelson – Contextualizing Kinship: A Bio-cultural Study of Families and Health in Jamaica

Robin Nelson: UCRIn this talk, I will explore the extent to which variability in the quality of familial and social relationships is correlated to the phenotypic expression of biological indicators of health status for adults and children. This research applies theories popularized in evolutionary ecology to a study of sociality and health in Manchester Parish, […]

William Harbaugh – Competitive preferences across age and gender

William Harbaugh: U of OregonOne potential explanation for some of the differences in incomes between men and women is a difference in preferences for economic competition. In experiments with real effort and cash payoffs men are more likely to select into winner-take-all tournaments, while women tend to choose individual piece-rate pay or equal payments based […]

Simone Schnall – Emotions, Intuitions, and Morality

Simone Schnall: CambridgeHow do people tell right from wrong? It used to be assumed that moral decisions are based on rational thought, such that people determine on objective facts and logical analysis what is morally acceptable behaviour. More recently, however, empirical findings suggest that decisions about morality and ethical behaviour are far from rational, but […]

James Andreoni – Accidental Altruism: Economic Research on the Social Aspects of Giving.

James Andreoni: UCSDGiving to those in need is inherently a social act. First, altruistic giving requires empathy for, or perhaps simply awareness of, those who are needy. Second, giving nearly always involves a social interaction between the donor and someone seeking a donation. Third, those who are generous tend to be admired by others, and […]

Joel Sachs – Evolutionary origins and stability of bacterial symbioses

Joel Sachs: UCRBeneficial bacteria improve our health and are crucial to crops plants and fodder animals. However, symbiosis is evolutionarily unstable: harmful mutants can invade symbiont populations and cause cooperation to collapse. My research encompasses both theoretical and empirical work on the evolution and maintenance of bacterial symbioses with eukaryotes. My theoretical work seeks to […]
