In the 90s Robert Axelrod has proposed a canonical model of social interactions explaining one of the possible and important mechanisms of the dissemination of culture. His idea started with a question: if peopletend to become more similar during an interaction, why don't all the differences eventually disappear? The model was very fruitful and managed to explain the issue. He has found that depending on initial conditions the system can end up in one of two states: ordered with global culture or disordered with many small subcultures. Others have studied the model deeper on complex networks and discovered that the structure has a crucial influence on the system. Despite this development, there was still a great unsolved issue - the model wascontradictory to empirical data considering language diversity. In mytalk, I will cover the most important publications on the model of socialinteractions and describe modifications necessary in order to make itconsistent with the empirical data.
