Local majority acceptance model of gossip dynamics
Abstract
We quantify the tendency of an individual to copy its local majority in a social network. Employing the majority rule leads to global consensus while opposing the majority leads to global polarization until some majority acceptance threshold at around 0.7–0.8. The density and distribution of connections strongly promote consensus while copying randomly from one's local neighborhood slightly diffuses it. The optimal strategy depends on the particular context and on the extent of majority acceptance, particularly for social systems. This study has applications for decision making processes and social organizations.
