Data from: Minority-group incubators and majority-group reservoirs for the diffusion of climate change adaptations

These data are part of a data portal that accompanies the special issue
'Climate change adaptation needs a science of culture,'
published in Philosophical Transactions of the Royal Society B in 2023. To
access the data portal, please visit 10.5061/dryad.bnzs7h4h4. This
repository contains code and supporting documentation for the agent-based
model analyzed in our paper, "Minority-group incubators and
majority-group reservoirs for climate change adaptation". We
performed and analyzed a suite of agent-based models that simulated the
spread of an adaptation, i.e., a beneficial behavior, in a population with
a minority and majority group, defined by group size and tendency to
interact with others from one's own group versus another group
(homophily). We ran 1000 trials per parameter setting, where parameters
were systematically varied to test different homophily levels in each
group, and the effect of whether the minority group, majority group, or
both groups start with one member knowing the adaptation. The adaptation
either spread from one agent in one or both groups to the rest of the
members of both groups in the case of adaptation success, or the
adaptation disappeared from the entire population (adaptation failure). We
then calculated the success rate across all 1000 trials. We also measured
the mean time to either adaptive success or failure.
