Altruistic behavior often comes at a personal cost, but there are also benefits. The person you help might return the favor directly — tit-for-tat. Or, people might talk about your good deeds, and reciprocity could come via a third party.  In a recent paper in Evolution and Human Behavior, SFI Graduate Fellow Victor Odouard and former Applied Complexity Fellow Michael Price explore the communication systems necessary to sustain indirect reciprocity.

When COVID-19 hit, SFI External Professor J. Doyne Farmer (University of Oxford) wanted to use his expertise to help predict how the economy would respond to the emerging pandemic. But the realities of COVID-19 — like so many of the concerns humanity currently faces — didn’t fit neatly into standard economic theory. It meant that he and his colleagues had to build new models based on “complexity economics” to make those predictions.

SFI hosted its first public conference-style event June 20-22 at the La Fonda Hotel in Santa Fe, New Mexico. The event, which focused on the foundations of collective intelligence and was a combined symposium and short course, drew over 200 in-person attendees and about 150 virtual participants from around the world. 

The British Academy announced its list of Fellows for 2023, which included SFI External Professor Wendy Carlin. She was among 52 other distinguished individuals recognized for their significant contributions to research in the humanities and social sciences.

In a new study published in the Proceedings of the National Academy of Sciences, authors Gabriel Gellner and Kevin McCann from the University of Guelph and SFI External Professor Alan Hastings (UC Davis) invert a classical approach to modeling food webs. Instead of trying to replicate stable, complex ecosystems using simplistic representations of species interactions, the authors’ novel inverse method assumes the ecosystems exist and works backward to characterize food webs that support that assumption.

The Network Science Society announced SFI External Professors Aaron Clauset and Tina Eliassi-Rad as two of their 2023 Fellows in recognition for their contributions in network science. The ceremony was held in Vienna, Austria as part of the International Conference on Network Science. 

There’s a debate among insect-cognition researchers, but the two camps have been arguing for so many decades that many onlookers are no longer sure what they are arguing about. SFI Postdoctoral Fellow Kelle Dhein, a philosopher and historian, published a paper in Studies in History and Philosophy of Science on February 28, 2023, clarifying the debate, with lessons for philosophers, historians, and scientists alike.

By using knowledge of phase transitions in physical systems, researchers can gain new insights into more efficient ways to answer questions about patterns and structures in sprawling datasets. SFI Professor Cris Moore recently organized a working group, held July 17–21 at SFI, that brought together experts from computer science, physics, and mathematics to explore connections between theoretical computer science and spin-glass theory, which is a framework for understanding phase transitions in complex materials. 

In the sprawling high-desert landscape between Santa Fe and Eldorado, nine of SFI’s postdocs gathered in late May at a quiet rental for 72 Hours of Science — an intense annual three-day retreat of community-building, creativity, and mad-dash research. 

Prediction is a key part of complex systems, in a wide variety of fields. Physicists and mathematicians use prediction performance to evaluate their models of mechanical systems; engineering prediction algorithms can inform the design of complicated devices. Prediction is also integral in artificial intelligence, in large language models like ChatGPT, which are designed to predict a word or words that follow from a prompt. A July 10–14 workshop at SFI called “Sensory Prediction: Engineered and Evolved” met to discuss how to build better models of prediction in living organisms.

SFI External Professor Tina Eliassi-Rad won the 2023 Lagrange Prize. The LaGrange Prize recognizes researchers and scientists for their excellence in the study of complexity. The award ceremony was held in Turin, Italy.  

Graduate students and early-career scholars, as well as change-makers in civil society and industry, based in South Asia and Africa are invited to apply for the first Complexity Global School (CGS) for Emerging Political Economies. CGS will run two concurrent schools — one in South Africa and one in India — December 3–15, 2023. All accepted participants will receive full scholarships, and travel stipends where applicable.

The Santa Fe Institute’s Board of Trustees welcomed Dan Tierney as a new member during the May 2023 Science Board & Board of Trustees Symposium. Tierney, an investor and the founder of Wicklow Capital, describes himself as a systems thinker, innately drawn to interdisciplinary approaches and innovation.

A June 13-15 workshop met to explore optimal regulations in diverse fields, ranging from biology and physics to corporate management.

Cormac McCarthy, a trustee of the Santa Fe Institute and one of the greatest American novelists, passed away on Tuesday, June 12, at his home in Santa Fe. He was 89 years old.

SFI External Professor France Córdova received an honorary doctorate from Yale University during its 2023 commencement ceremony in May. Granted the degree of Doctor of Science, Córdova was one of nine honorary graduates.

SFI Fractal Faculty member Kyle Harper, who joined SFI in August 2022, takes an unconventional approach to his studies of Roman history at the University of Oklahoma. With a long-held interest in physics, Harper brings a complex-systems lens to the study of the human past as he explores the rise of technologies, environmental change and constraints, and the spread of diseases. In July 2022, Harper sat down to talk with SFI President David Krakauer about his work. Here are clips from their conversation.

In a new study published in PNAS, External Professor and UC Davis professor emeritus Alan Hastings and colleagues analyzed a case of social contagion in Adouin's gulls in Spain.

SFI's David Wolpert's No-free-lunch theorems have stirred up many opinions over the past few decades. Wolpert chimes in on the conversation in a new piece in the Journal for General Philosophy of Science.

James Hartle, External Professor at the Santa Fe Institute and Professor of Physics Emeritus at the University of California, Santa Barbara, passed away on May 17 in Switzerland at the age of 83. A longtime familiar face at SFI, Jim offered profound insights into conversations in a characteristically gentle manner. He will be missed immensely.
