Study: Countering hate on social media
Santa Fe Institute

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.

The Rhythm of Change: What a Drum-Beat Experiment Reveals About Cultural Evolution
Santa Fe Institute

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.

Tiny worlds reveal fundamental drivers of abundance, diversity
Santa Fe Institute

Ecology is traditionally a data-poor discipline, but tiny microbial worlds offer the quantity of data needed to solve universal questions about abundance and diversity. New research in Nature Communications reveals the fundamental relationship between the environment and the species present in a microbial community and can be used as a starting point for investigating bigger systems.

New model shows how voting behavior can drive political parties apart
Santa Fe Institute

If voters gravitate toward the center of the political spectrum, why are the parties drifting farther apart? A new model reveals a mechanism for increased polarization in U.S. politics, guided by the idea of "satisficing"-- that people will settle for a candidate who is "good enough."

Leaving money on the table to stay in the game: New paper squares economic choice with evolutionary survival
Santa Fe Institute

Unlike businesses or governments, organisms can't go into evolutionary debt -- there is no borrowing one's way back from extinction. This can lead to seemingly irrational economic choices that suddenly make sense when viewed as a multiplicative, evolutionary process.

More ecosystem engineers create stability, preventing extinctions
Santa Fe Institute

Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of "ecosystem engineers" stabilizes the entire network against extinctions.

COVID-19 U.S. Employment Shocks Likely Larger Than Great Depression
Santa Fe Institute

The U.S. is likely to see a near-term 24% drop in employment, 17% percent drop in wages, and 22% drop in economic activity as a result of the COVID-19 crisis according to a new study. These impacts will be very unevenly distributed, with the bottom quarter of earners at risk of a 42% loss in employment and bearing a 30% share of total wage losses. In contrast, the study estimates the top quarter of earners only risk a 7% drop in employment and an 18% share of wage losses.

What is an individual? Information Theory may provide the answer
Santa Fe Institute

Despite the near-universal assumption of individuality in biology, there is little agreement about what individuals are and few rigorous quantitative methods for their identification. A new approach may solve the problem by defining individuals in terms of informational processes.

Complexity scientists available to discuss implications of COVID-19 pandemic
Santa Fe Institute

The COVID-19 pandemic is an example of complexity in action. Researchers who study complex systems are available to answer questions on topics such as why systems collapse, the nature of an evolving virus and its ecology, how networks spread disease and economic instability, the mathematics of modeling outbreaks, the way decision-making modifies disease spread, and other ideas that touch on the disease.

If cancer were easy, every cell would do it
Santa Fe Institute

A new paper puts an evolutionary twist on a classic question. Instead of asking why we get cancer, researchers at Osnabrück University and the Santa Fe Institute use signaling theory to explore how our bodies have evolved to keep us from getting more cancer.

‘Like a video game with health points,’ energy budgets explain evolutionary body size
Santa Fe Institute

Budgeting resources isn’t just a problem for humans preparing a holiday dinner, or squirrels storing up nuts for the winter. A new model of how animals budget their energy sheds light on how they live and explains why they tend to evolve toward larger body sizes. The research, published in PNAS, proposes that animal energy budgets are governed by a key mechanism: resource variation — a measure of how spread out or clumped up food and water are.

This ‘Fix’ for Economic Theory Changes Everything From Gambles to Inequality to Ponzi Schemes
Santa Fe Institute

Whether we decide to take out that insurance policy, buy Bitcoin, or switch jobs, many economic decisions boil down to a fundamental gamble about how to maximize our wealth over time. How we understand these decisions is the subject of a new perspective piece in Nature Physics that aims to correct a foundational mistake in economic theory.

The result of the 2016 US presidential election was, for many, a surprise lesson in social perception bias — peoples’ tendency to assume that others think as we do, and to underestimate the size and influence of a minority party. Long documented in psychological literature, a panoply of social perception biases play out differently in different contexts. Many psychologists attribute the source of these biases to faulty cognitive processes like “wishful thinking” or “social projection,” but according to a study published August 12 in Nature Human Behaviour, the structure of our social networks might offer a simpler explanation.

Researchers at the Max Planck Institute and the Santa Fe Institute have developed a new model to explain the evolutionary origins of empathy and other related phenomena, such as emotional contagion and contagious yawning. The model suggests that the origin of a broad range of empathetic responses lies in cognitive simulation. It shifts the theoretical focus from a top-down approach that begins with cooperation to one that begins with a single cognitive mechanism.
