Using evolutionary dynamics and game theory to understand personal relations
When we ask friends if we can stay at their place, we prefer them to say yes without asking details such as for how long. Yet, if the answer is going to be no, then we often prefer them to seek more information from us first. At first glance, this situation seems very different from how we react when we are in an exclusive relationship and our partner flirts with someone else. However, a probability-based analysis with Bayesian game theory shows that each involves differing degrees of manipulation and preferential interaction, MIT researchers report in a recent paper. MIT postdoc Alfonso Pérez-Escudero and colleagues analyzed how these manipulation and preferential interaction mechanisms play out in “the envelope game,” a framework developed by Harvard University researchers Martin Nowak, Erez Yoeli, and Moshe Hoffman. “These are two situations that, in principle, I wouldn’t put together, and thanks to the framework that these researchers developed,...
