Emergence of Social Badges — •Gorm Gruner Jensen and Stefan Bornholdt — Universität Bremen, Bremen, Deutschland

Social badges, easily detectable physical traits that strongly correlate with social status, are found in a wide variety of biological species. It is usually assumed that such badges signal an intrinsic strength, warning potential competitors to stay away and attracting potential mates. Under this assumption it is generally understood, that the correlation between badge and intrinsic strength must be strong in order for the receiver to benefit from reacting to it, and the badge must come at a cost in order to avoid false replicas.

We will present a different view, by introducing a minimalistic model in which the badge precedes any intrinsic property. The correlation between badge and social status emerges as a self-organized property due to the collective behavior of individual agents whose strength is affected by their self esteem, and whose self esteem is faithfully inferred from previous experience.
