A general model of human mate choice in which agents are localized in space, interact with close neighbors, and tend to range either near or far. At the individual level, our model uses two oft-used but incompletely understood decision rules: one based on preferences for similar partners, the other for maximally attractive partners.
We develop a spatial, evolutionary model of the endogenous formation and dissolution of groups using a renewable common pool resource. We use this foundation to measure the evolutionary pressures at different organizational levels.
A spatial prisoner’s dilemma model with mobile agents, de-coupled birth-death events, and harsh environments.
We consider scientific communities where each scientist employs one of two characteristic methods: an “all right” method (A) and a “better method” (B). The quality of methodology is relevant to the epistemic products of these scientists, and generate credit for their users. Higher-credit methods tend to be imitated, allowing to explore whether communities will adopt one method or the other. We use the model to examine the effects of (1) bias for existing methods, (2) competence to assess relative value of competing methods, and (3) interdisciplinarity: the tendency for members of a scientific community to receive meaningful credit assignment from those outside their community.
