In a recent study in Physical Review Letters, SFI Complexity Postdoctoral Fellow Aanjaneya Kumar and colleagues show that the ...

Societies today face daunting challenges: population growth, rapid urbanization, ecological and environmental disturbances, and an unpredictable global marketplace. To address these complex and ...

We develop a unifying approach for complexity measures, based on the principle that complexity requires interactions at different scales of description. Complex systems are more than the sum of their ...

This paper formally defines tipping points as a discontinuity between current and future states of a system and introduces candidate measures of when a system tips based on changes in the probability ...

The Santa Fe Institute is an independent, nonprofit research and education center that leads global research in complexity science. SFI scientists seek the shared patterns and regularities across ...

How do people make judgments about characteristics of their peers? We investigate what cognitive strategies underlie peer judgments, what group-level patterns of judgments do these strategies produce, ...

Complex adaptive systems (CAS) consist of many interacting and adapting components. Echo is a computational CAS model in which evolving agents are situated in a resource-limited environment. Different ...

The adoption and diffusion of new technologies, including those associated with energy distribution and management, requires a deep appreciation of the properties and diversity of social systems.

Themes are institute-wide research topics that draw together large networks of researchers from the extended SFI network and beyond. Over the course of several years, researchers rigorously engage ...

We propose a theory of asset pricing based on heterogeneous agents who continually adapt their expectations to the market that these expectations aggregatively create. And we explore the implications ...

Polygyny is thought to be more prevalent where male wealth inequality is greater; however, the decline of polygyny in most of the world occurred with the emergence of capital-intensive farming with ...

Norris, J. Q.,Turcotte, D. L.,Moores, E. M.,Brodsky, E. E.,Rundle, J. B. Fracking is a popular term referring to hydraulic fracturing when it is used to extract hydrocarbons. We distinguish between ...
