People not only form social networks, they construct mental maps of them. People think about the ties between other people, including ties among individuals to whom they are not themselves directly connected. These “cognitive social networks” have rarely been studied. 1/

in a sequential social learning scenario, a sequence of agents make binary decisions on the basis of their private signals and information available to them from past choices. information cascade in this scenario refers to discounting of new private information in favor of past public actions

You can bound Rényi divergences in terms of KL divergences for tilted distributions. This is useful e.g. for Gaussians, where tilting just corresponds to shifting the distribution.

Aumann's agreement theorem says that two Bayesians who share a common prior and have common knowledge of each other's posteriors must share the same posterior --- i.e. they cannot "agree to disagree". But people disagree all the time. What is your favorite hypothesis about how come?
