I presented work on “Corruption, Cooperation, & the Evolution of Prosocial Institutions”, including some new work on the evolution of evil eye belief and related behaviors at the CIFAR Institutions, Organizations, and Growth program’s annual meeting.
Part of this work was based on a recent paper published in Nature Human Behaviour, with some context published in Evonomics and ProMarket (pre-print). The other part was work in progress on understanding the evolution of evil eye.
I also discussed the general approach to understanding corruption using cultural evolution and the science of cooperation – corruption is one scale of cooperation undermining another. For example, nepotism is cooperation at the scale of kin, well explained by inclusive fitness, undermining cooperation at the scale of the formal institution. More on this framework can be found at ProMarket or Evonomics. Finally, I presented some work in progress based on this approach, including some work by my students.
I gave a keynote presentation at the Lorentz Center conference on “Trusting and the Law“. This was my first legal conference. The audience included judges, lawyers, and legal scholars. I presented a talk on “Economic Psychology and the Science of Cultural Evolution”, where I discussed some of the “invisible cultural pillars” that uphold legal institutions. It was fascinating to discuss differences in the approach to “evidence” in science and the law.
I was invited to present my work on innovation and cultural evolution at the “Cultural Transmission and Social Norms Workshop” hosted by the School of Economics at The University of East Anglia, UK. I presented “Innovation in the Collective Brain: The Transmission and Evolution of Norms and Culture”, beginning with an introduction to cultural evolution for the audience of primarily economists. I then discussed innovation as a product of our “collective brains“.
I was invited to present my work on human evolution and the evolution of brains at the “Evolution of cognition and longevity: Adaptation to a new technological environment” meeting at the Grande Galerie de l’Evolution, National Museum of Natural History in Paris, France. I presented “The Cultural Brain Hypothesis & Information Grandmother Hypothesis: How culture drives brain expansion and alters life history”, where I discussed the Cultural Brain Hypothesis (my dissertation; paper currently under review). I also presented some work in progress on the Information Grandmother Hypothesis.
The Cultural Brain Hypothesis is a more parsimonious explanation for the relationships that have been shown between brain size, group size, adaptive knowledge, social learning, and aspects of life history. The Cumulative Cultural Brain Hypothesis is a set of predictions derived from the evolutionary processes that lead to these relationships for the conditions that lead to an autocatalytic take-off between brain size and adaptive knowledge – the uniquely human pathway. The Information Grandmother Hypothesis extends this theory to explain the evolution of menopause and lifespan.
Speakers were biologists of all kinds. Speakers included:
I spent the last week back at Harvard University discussing research on cultural evolution and innovation with the Learning Innovations Laboratory (LILA), part of Project Zero at the Harvard Graduate School of Education. The LILA group include people from industry and the military. Every year the group invites two academics to discuss their research and how it might be applied to problems faced by members of the group. This year, Mary Ann Glynn and I were invited. It was an intellectually enriching opportunity to apply my work to current challenges in corporations and other organizations.
The ideas presented in my two talks were beautifully captured in the graphics below:
The Science of Cultural Evolution: What Makes Humans So Different
Sources of Innovation: The Secret of Human Success
I spent the weekend at a productive interdisciplinary workshop on “Religion, Ritual, Conflict, and Cooperation: Archaeological and Historical Approaches” at the Center for Advanced Study in the Behavioral Sciences (CASBS) at Stanford University. CASBS is located on the top of one of the beautiful hills around Stanford.
We discussed the challenges and successes in inferring religious belief and practice from the archeological and historical record and new theoretical models and tools for exploring religious history, including the Database of Religious History (DRH).
I was invited to present the Database of Religious History at the Department of Statistics Seminar Series. Nancy Heckman, Head of the Statistics Department, watched our award winning video on the database and was interested in possible connections with researchers in statistics. I presented some of the technical design aspects of the database as well as our statistical approach to analyzing the data.
Afterwards, I had lunch with several members of the department, including Nancy Heckman, Ruben Zamar, Cindy Greenwood, and Davor Cubranic, as well as with Andrew Trites, Director of the Marine Mammal Research Unit and North Pacific Universities Marine Mammal Research Consortium and Fisheries Centre Co-Director. I hope that collaborations with the Department of Statistics will allow us to find new ways to share and analyze our rapidly growing data.
The Cultural Brain Hypothesis (in prep; co-authored with Maciek Chudek and Joe Henrich) describes the evolution of large brains and parsimoniously explains several empirical relationships between brain size, group size, social learning, mating structures, culture, and the juvenile period. The model also describes the selection pressures that may have led humans into the realm of cumulative cultural evolution, further driving up the human brain size.

Sociality Influences Cultural Complexity (2014; co-authored with Ben Shulman, Vlad Vasilescu, and Joe Henrich) on the relationship between sociality and cultural complexity.
This week I visited the University of St Andrews, Scotland. Kevin Laland invited me to present my paper (in prep) on the Cultural Brain Hypothesis and the Cumulative Cultural Brain Hypothesis. The paper, co-authored with Maciek Chudek and Joe Henrich, describes an evolutionary model of the evolution of brains and parsimoniously explains several empirical relationships between brain size, group size, social learning, mating structures, culture, and the juvenile period. The model also describes the selection pressures that may have led humans into the realm of cumulative cultural evolution, further driving up the human brain size. I presented the research to Kevin’s lab and to Andy Whiten’s lab. I will also be presenting the paper early next month at the 26th Annual Meeting of Human Behavior and Evolution Society (HBES) in Natal, Brazil.
I was invited by the Social Sciences and Humanities Research Council to elaborate on the vision and achievements of the Database of Religious History, complementing the winning video, which you can watch below:
The panel of 4 judges included Shari Graydon, author, journalist and founder of Informed Opinions; Antonia Maioni, president of the Federation for the Humanities and Social Sciences; Pierre Normand, Vice-President, External Relations and Communications at the Canada Foundation for Innovation; and Bruce Wallace, editor of Policy Options magazine and former foreign editor for the Los Angeles Times.
I will be presenting the same talk to a VIP audience at SSHRC’s 2014 Impact Awards ceremony in early November.
