Social learning with complex contagion — new work by Hiroaki Chiba-Okabe.

We introduce a framework that combines payoff-based imitation with conformity or anti-conformity biases, and we study long-term behavioral outcomes in a population.

How to judge someone when we have lots of info about their behavior? Our study shows that "looking twice and forgiving once" builds informative reputations that sustain cooperation—no complex norms or public institutions needed🧵👇

"Look twice, forgive once" – a simple and effective way of judging each other's social behavior....

...thanks to new work from Sebastián Michel-Mata et al.

[City of Philadelphia @PhiladelphiaGov]

The City of Philadelphia is committed to improving the region’s trail network for pedestrians and cyclists.

The Christian to Crescent trail segment will connect the existing Schuylkill River Trail, which ends at Christian Street, to the Grays Ferry Crescent Trail.

@al_cibiades @IULuddy Very happy to have you stateside. Congrats. (Although I’ll miss the golf carts)

We work to provide a systematic account of how risk preferences modulate, and even coevolve with, behavior in an uncertain social world.

Hopefully this framework will help us understand complex dynamics that arise from the interplay of strategic imitation and risk tolerances.

[Joshua B. Plotkin @jplotkin]

When individuals update their risk preferences along with their strategic behaviors, a population can oscillate between periods dominated by risk-averse cooperators and periods of risk-seeking defectors.

[Joshua B. Plotkin @jplotkin]

We extend evolutionary game theory to incorporate noise in payoff observation and variation in attitudes towards risk. Different risk preference can substantially alter long-term behavioral outcomes, such as promoting cooperation that would otherwise be dominated by defection.

The evolution of social behaviors and risk preferences in settings with uncertainty.

New work from Guocheng Wang et al, where we study behavioral evolution when payoff observations are noisy.

I am excited to share that I will be starting a lab at @EmoryUniversity this September. We will aim to understand evolution by studying genomes of things ranging from viruses to humans. Looking for talented students and postdocs to do computational genomics. Get in touch! 1/2
