It’s widely assumed within the evolutionary biology field that weak selection provides an advantage to an organism’s ability to evolve. But new research, published in the journal Science, may offer the first experimental proof that strong selection pressure enhances an organism's evolvability, by boosting robustness.
In a new paper published in the journal Social Cognition, SFI Postdoctoral Fellow Jonas Dalege and co-author Han L. J. van der Maas use their network theory of attitudes to model implicit measures.
New book: Complexity Economics explores paradigm-busting influence of complex systems science on economics
In a new book published by the SFI Press, editors W. Brian Arthur, Eric Beinhocker, and Allison Stanger explore the paradigm-busting influence of complex systems science on economics.
In their op-ed for Nautilus, SFI External Professor Melanie Moses (University of New Mexico) and her colleague Kathy L. Powers (University of New Mexico), argue that if scientists are to help public health policymakers meet their stated goal of protecting the most vulnerable, they must refine their methods to focus on the complex systems that govern communities that are most at risk.
The rise of online hate speech is a disturbing, growing trend in countries around the world, with serious psychological consequences and the potential to impact, and even contribute to, real-world violence. A new paper offers a framework for studying the dynamics of online hate and counter speech, and offers the first large-scale classification of millions of instances such interactions on Twitter.
In a post-election op-ed for The Conversation, SFI Professor Mirta Galesic and Wändi Bruine de Bruin at USC Dornsife describe their polling research with colleagues Henrik Olssen, SFI External Professor, and Drazen Prelec at MIT. The team found that if polls start to ask questions about how people think members of their social circle or state will vote, they tend to predict results with far greater accuracy.
Until now, systems far from thermal equilibrium couldn’t be analyzed with conventional thermodynamics and statistical physics. In a paper published in Physical Review Letters, David Wolpert presents a new hybrid formalism to overcome these limitations.
One characteristic shared by most human civilzations in the last 10,000 years was a reliance on innovations in collective information processing to grow beyond a certain size and scale, according to research published in Nature Communications by Santa Fe Institute Professor David Wolpert, External Professor Tim Kohler (Washington State University), and other SFI collaborators.
It takes patience and plenty of good-will to transform a dynamic and intensive in-person summer program into a virtual experience that offers genuine and impactful connections. With the support of SFI Professor and Program Director Chris Kempes and Education Program Manager Carla Shedivy, ten students around the U.S. and 11 SFI researcher-mentors proved up to the task.
Living organisms aren’t the only things that evolve over time. Cultural practices change, too, and in recent years social scientists have taken a keen interest in understanding this cultural evolution. A new experiment used drum-beats to investigate the role that environment plays on cultural shifts, confirming that different environments do indeed give rise to different cultural patterns.
How to reach emissions reduction targets while simultaneously growing New Mexico’s economy is the subject of a new report from a Santa Fe Institute workshop, which describes opportunities for New Mexico to fuel job growth and take a leading role in the Southwest region as it moves toward decarbonization.
In a special presentation for the online ScienceWriters2020 conference in October, SFI’s Joshua Garland and Mirta Galesic will present the first large-scale analysis of tens of millions of instances of hate and counter-hate speech on Twitter.
If voters gravitate toward the center of the political spectrum, why are the parties drifting farther apart? At the latest meeting of SFI’s Virtual Science Club on Sept. 16, Vicky Chuqiao Yang, an SFI Omidyar Fellow and Peters Hurst Scholar, showed 40 attendees how dynamic mathematical models can help us make sense of this and other puzzles of politics and voting
A new video mini-series, “Andromeda Strain and the Meaning of Life,” will explore major questions around astrobiology and life’s origins through imaginative conversations between six leading researchers in the field.
