Emergence and Decline of Scientific Paradigms in a Two-Group System

Idea spreading is an important process in science and society. In this work, we study this spreading process in a population consisting of two groups based on a recent model proposed by Bornholdt et al. We consider two types of division in the population: regular and random division. We find some interesting phenomena, for example, the exchange of dominant ideas between the two groups in the cases of regular and the random division, and the appearance of a novel stage in which a few ideas interact strongly to seek a balance.
