Information spreading and multi-stability in social systems — •Kim Sneppen — Niels Bohr Institute, Copenhagen, Denmark

Information spreading and “winner takes all" competition are ingredients in social system formation. Using word spreading and language competition as model systems, I will discuss [1] a simple model for word spreading, that emphasize information age as a selection principle, [2] a simple model for idea spreading, that emphasize the effect of social thresholds and [3] a model for preservation of diversity when multiple languages/opinions compete for dominance. Finally, I will briefly discuss implications for scale free versus modular structures of social networks [4].
