Transmission T-035: Amos Golan on info-metrics for modeling and inference with complex and uncertain pandemic information
We must use a modeling approach to COVID-19 data that will yield the least biased inference and prediction.
When thinking about reopening schools, an important factor to consider is the rate of community transmission.
Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research by former Omidyar Fellow Justin Yeakel, which finds that increasing the number of "ecosystem engineers" stabilizes the entire network against extinctions.
Human cognition and cultural norms have changed the composition of human portraits, according to a new analysis of European paintings from the 15th to the 20th century. The study, led by SFI Omidyar Fellow Helena Miton, examined "bias" in 1831 paintings by 582 unique European painters.
Our thoughts are with the many victims of disease, abuse, injustice, and exclusion. Black lives and Native lives matter. Our community of complexity researchers are aligned with all who are committed to freedom, justice, diversity, opportunity, and empiricism. We stand with those who strive to provide the most powerful ideas, methods, and tools pursuant to a civil and equitable society. We add our voice to the moment, defend freedom of expression, and offer all that we can in pursuit of a safer and fairer world.
Swing voters, swing stocks, swing users: Scientists develop a general technique for identifying swing components
A new technique could help identify prime candidates for changing election outcomes, or lead to a better understanding of how institutional and environmental factors shape the emergence of social structure.
Well-mixed models do not protect the vulnerable in segregated societies.
Transmission T-033: Brian Enquist on how pandemics rapidly reshape the evolutionary & ecological landscape
Pandemics rapidly reshape the evolutionary and ecological landscape and have cascading social, economic, and other system-level effects.
The countervailing pressures of economic pain and disease containment are keeping the COVID-19 pandemic at a noisy equilibrium.
The COVID-19 pandemic offers an opportunity to out-evolve the virus by evolving our own scientific ingenuity and social practices.
External Professor Emeritus Constantino Tsallis and his colleague describe a single function that accurately describes all existing available data on active COVID-19 cases and deaths—and aims to predict forthcoming peaks.
For students who participate in SFI’s Undergraduate Complexity Research program, the 10-week residential opportunity not only develops their research skills, it opens their minds to new concepts and builds lasting relationships. We recently caught up with two students who attended the 2019 session.
SFI Trustee Katherine Collins and ACtioN member Putnam Investments are co-hosting a Virtual Topical Meeting May 27-28 to explore how complexity science can inform sustainable investing. The meeting will bring investors together with leading climate and complexity scientists to discuss “The Complexity of Sustainability and Investing.”
On April 15, SFI hosted a flash discussion that focused on human behavior, incentives, and beliefs. The overarching message was that the financial and social fallout of the pandemic, while difficult to predict, will largely depend on actions at individual, community, and institutional levels.
Study: ‘Near-unliveable’ heat for one-third of humans within 50 years if greenhouse gas emissions are not cut
Areas of the planet home to one-third of humans will become as hot as the hottest parts of the Sahara within 50 years, unless greenhouse gas emissions fall, according to research by an international research team of archaeologists, ecologists, and climate scientists. The study, which was published in the Proceedings of the National Academy of Sciences this week, resulted from a 2018 SFI working group on climate change and the human "niche." It finds that rapid heating would mean that 3.5 billion people would live outside the temperature and humidity combinations in which humans have thrived for 6,000 years.
SFI welcomes Omidyar Fellow Anjali Bhatt, who holds an AB in physics from Harvard University and is completing a PhD in organizational behavior at Stanford Graduate School of Business, and blends organizational and cultural theories, which are grounded in sociology, with the mathematical models of evolutionary biology and the quantitative tools of computational linguistics.
SFI welcomes Progam Postdoctoral Fellow Jonas Dalege, who holds a PhD in psychology as well as a BSc and MSc from the University of Amsterdam and will work with SFI Professor Mirta Galesic and External Professor Henrik Olsson to develop a unifying theoretical framework that integrates two approaches to understanding our ability to develop and maintain beliefs.
