Tenth international online seminar "Artificial Societies and Information Technologies"

On 02.04.2021, a meeting of the international online seminar "Artificial Societies and Information Technologies" was held, dedicated to the report of Guillaume Deffuan (National Institute of Agronomic Research, Paris, France).

Presentation topic: Reducing perceived inequality leads to an increase in the average opinion of each other

Abstract:

We are looking at a recently published model in which agents hold opinions of each other and influence each other's opinions during random pairwise interactions. This model exhibits striking patterns: no gossip, initialized to 0, mean opinion increases until it stabilizes at a significant positive value; with gossip, the average opinion hovers around a negative value. We derive a mean noise effect model that explains these patterns as a result of competition between negative and positive biases. It also explains why the negative effect of gossip only occurs when the reputation of agents is very unequal and affects agents with a lower reputation more strongly.
