Correlation between the initial number of susceptible individuals and the popularity of each belief, given the same final distribution of adoption between conditions; detail shows t = 9 popularity vs. number of individuals initially susceptible. C. Correlation between the popularity of each belief and the popularity of the most popular belief it shares a ’node’ with; sample t = 9 popularity of each belief overlaid on the knowledge graph. D. Clustering coefficient of a hypothetical knowledge graph made up of the most popular 10% of all beliefs; sample t = 9 network filtered on popularity.

By contrast, under interdependent diffusion each belief has a particular likelihood of adoption...
