> Contemporary societies are often “polarized”, in the sense that sub-groups
> within these societies hold stably opposing beliefs, even when there is a
> fact of the matter. Extant models of polarization do not capture the idea
> that some beliefs are true and others false. Here we present a model, based
> on the network epistemology framework of Bala and Goyal (Learning from
> neighbors, Rev. Econ. Stud. 65(3), 784–811 1998), in which polarization
> emerges even though agents gather evidence about their beliefs, and true
> belief yields a pay-off advantage. As we discuss, these results are
> especially relevant to polarization in scientific communities, for these
> reasons. The key mechanism that generates polarization involves treating
> evidence generated by other agents as uncertain when their beliefs are
> relatively different from one’s own.
