In social networks, group boundaries promote the spread of ideas, study finds

Social influence how ideas and beliefs can spread around a society. In this study, the University of Pennsylvania’s Damon Centola shows that networks that are very diffuse (left) make it hard for ideas to catch on, while networks with very strong group boundaries (right) make it almost impossible for ideas to spread. A network that was moderately “grouped,” however, was most conducive to spreading complex ideas.
