I was delighted to be an invited speaker at the meeting on “Creativity: innovation, transmission, and motivation in animals, humans, and societies,” which took place at the Pontifical University of the Holy Cross in Rome. The meeting is part of an effort to strengthen the relationship between the Vatican and science.
I presented my research on “Cultural Evolution and Creativity in the Collective Brain”, including new work, my book, A Theory of Everyone, and previous work in these papers:

This event brought together an interdisciplinary array of scholars, priests, and researchers, and I am looking forward to continuing this important dialogue.
Ted Slingerland, M. Willis Monroe, and I were awarded a John Templeton Foundation grant for The Database of Religious History: “Exploring the Cultural Evolution of Religion Employing a Large-Scale, Quantitative-Qualitative Historical Database” ($4,792,151). The grant will take us through to 2023.
We will be hiring several new postdocs to expand the time depth, geographic range, and domains of data collection efforts. If you notice your area of expertise missing from our dataset, please reach out. Otherwise, stay tuned for job ads.
New paper on “Psychology as a historical science” in Annual Review of Psychology. Catalyzing the field of “historical psychology” by reviewing work on: origins of psychology and institutions today, psychology of the past (data from dead minds).
Our psychology is shaped by our societies, and our societies are shaped by their histories. We can do better than butterfly collecting–just measuring cross-cultural diffs. For psychology to develop a full theory of human behavior, we need historical psychology.
Psychology is shaped by millions of years of genetic evolution, thousands of years of cultural evolution, & a short lifetime of experience; yet, much of the field has focused on that short lifetime of experience. The WEIRD People Problem is not only about geography but history.
Past societies can be as culturally distant as distant societies. Cohort effects are a sliver of the cross-temporal variation we would expect in a culturally evolving species. History serves as a kind of psychological fossil record, a source of “data from dead minds”.
We (1) review work in historical psychology; (2) introduce methods including causal inference & how to extract data from dead minds; (3) explore the role of theory in mapping history to psychology; and (4) provide some conclusions concerning the future of this field.
E.g.s: Religious evolution & social psych. Some gods gained the ability to see into hearts & control an afterlife contingent on compliance. In many large-scale societies, these gods became omniscient, omnipotent, & omnibenevolent, coevolving with the scale of their societies.
This historical theory makes predictions not only about expected relationships in the historical record but also about expected contemporary cross-cultural diversity in religious beliefs and cognition. In doing so, the theory links historical psychology to cultural psychology.
WEIRD Psychology may have its origins in suppressing kin networks, changing family structures, & related via one particular religion: The Catholic Church
Institutions rest on invisible cultural and psychological pillars. E.g. a constitution’s proclamations are irrelevant without a belief in the rule of law, or norms of punishment for violations of this rule.
We discuss the importance of causal inference techniques in historical psychology: instrumental variables, difference-in-differences, regression discontinuity. Some e.g. use for slavery & trust in strangers; agriculture & sex diff, gender inequality, collectivism; personality.
Historical psychology includes the psychology of the past – data from dead minds, cognitive archeology. Historical databases are emerging. But sometimes the data is qualitative requiring tools like text analysis.
We discuss some examples of the importance of theory. A society has codependent norms, values, beliefs, behaviors, and institutions. If one takes an exploratory approach and looks for correlations in history, there are many to be found. Theory helps clarify causality.
Collaboration between psychologists, historians, and other humanities scholars is important (see religiondatabase.org for an e.g.). We discuss challenges & strategies.
Taking history seriously is a critical part of moving beyond the WEIRD people problem and making psychology a genuinely universal science of human cognition and behavior.
Keynote at Symposion Dürnstein on Heritages: Culture Nature Identity in the beautiful Dürnstein Abbey (Stift Dürnstein), Dürnstein, Austria. I discussed cultural evolution, the evolution of religion, and the challenges of multiculturalism.

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 chaired a symposium on “Understanding Religions: Integrating experimental, ethnographic and historical approaches” at the Society for Personality and Social Psychology (SPSP) conference in San Diego, CA.
Joe Henrich began by introducing the broader research agenda, describing the two puzzles of (1) the rise of societal complexity and large-scale cooperation and (2) the emergence and spread of particular religious elements, such as big, powerful, moralizing gods and ritual behavior.
Coren Apicella presented recent evidence of high levels of rule bending in the Hadza, a a minimally religious foraging population.
I then introduced the Database of Religious History and presented some preliminary analyses, showing the relationship between ritual and cooperative behavior. I also updated the audience on data collection and some of the directions we’re going in (such as measuring cultural distance–more soon!).
Finally, Ted Slingerland gave an overview of what the humanities can offer the psychology of religion, with an entertaining presentation of how a lack of deep understanding of history and culture can lead to misinterpretations (such as claims that Chinese don’t have religious beliefs, nor mind-body dualism).
