Echo Chambers in the Ising Model

Synopsis

The echo-chamber effect is a common term in opinion dynamic modeling to describe how a person’s opinion might be artificially enhanced as it is reflected back at her through social interactions. In the talk I will discuss the existence of this effect in statistical mechanics models, which are commonly used to study opinion dynamics.I will show that the Ising model does not exhibit echo-chambers, but this result is a consequence of a special symmetry, which is not very common in other models.
